微波烘干的干燥控制方法、系统、设备、仿真优化及应用Drying control method, system, equipment, simulation optimization and application of microwave drying

技术领域technical field

本发明属于微波烘干技术领域，尤其涉及一种微波烘干的干燥控制方法、系统、设备、仿真优化及应用。The invention belongs to the technical field of microwave drying, and in particular relates to a drying control method, system, equipment, simulation optimization and application of microwave drying.

背景技术Background technique

目前：水性漆涂装分为机器喷涂和人工喷涂两种：机器喷涂现在市场上较成熟的有往复机、五轴机、喷淋机、真空喷涂机等，这种设备投入成本较大，且须有一定的产量支持；还有一种是人工喷涂。传统喷枪加隔膜泵喷涂不用改造，节省费用，但出枪的流畅性较差。传统喷枪加供油压力桶用压力压送油漆出枪，适量减少空气压，减少油漆的反弹。节约油漆成本、设备投入小。科姆林高压泵浦配套高压枪，漆膜雾化好，涂料利用率高，成本加大。因水性漆粘度较高而喷涂流畅较差，所以人工喷涂建议增加压力桶或使用克姆林喷枪(混气喷涂)。At present: water-based paint coating is divided into two types: machine spraying and manual spraying: machine spraying is now more mature in the market, such as reciprocating machine, five-axis machine, sprayer, vacuum sprayer, etc. This equipment has a large investment cost, and There must be a certain amount of production support; another is manual spraying. The traditional spray gun and diaphragm pump do not need to be modified for spraying, which saves costs, but the smoothness of the gun is poor. The traditional spray gun and the oil supply pressure barrel use pressure to send the paint out of the gun, reduce the air pressure in an appropriate amount, and reduce the rebound of the paint. Save paint cost and equipment investment is small. Comlin's high-pressure pump is equipped with a high-pressure gun, which has good paint film atomization, high paint utilization, and increased cost. Due to the high viscosity of water-based paint, the spraying flow is poor, so it is recommended to increase the pressure bucket or use a Kemlin spray gun (air-mixing spraying) for manual spraying.

水性漆是一种以水为介质的环保型无公害涂料，如何提高水性漆家具的烘干时间并保持被涂装板料的品质，是水性漆家具生产加工的一大难题。Water-based paint is an environmentally friendly and pollution-free paint with water as the medium. How to improve the drying time of water-based paint furniture and maintain the quality of the coated sheet is a major problem in the production and processing of water-based paint furniture.

目前国内水性漆涂装行业的兴起，传统的烘干方式已经不足以满足国内市场需求以及环保要求为背景，微波借助高频电磁振荡使水性漆中的极性水分子运动和相互摩擦，产生热量，是一种很有应用前景加热方式，具有加热快、穿透强的优势，从而可以提升水性漆涂装物料的干燥效率，提高产业效能。据统计，美国人均年消费家具236美元、德国人年均消费家具371美元，日本人均年消费家具255美元，而我国大约在12美元左右，仅仅是欧美等发达国家的5％都不到。尤其是二三线市场、广大农村市场家具的占有率则更低。中国人真正买成套家具和坐上沙发的人不到4个亿，这说明还有2/3的人还没有用上现代家具。这为家具行业进一步发展带来巨大的契机，也使得涂料行业的前景巨大。而油漆挥发的VOC中，包含苯、酯、醛等，这些对人体危害严重，吸入过量会引发头晕、胸闷、咳嗽等症状，甚至会导致胸膜炎、癌症、白血病等病症的发生。来自国家环境监测中心公布的数字显示，每年因接触油漆而发生的中毒死亡人数多达11万人，平均每天约为304人。水性涂料替代油漆是趋势。传统的家具水性漆干燥主要有4种方式：自然干燥、紫外线干燥、红外线干燥、热空气干燥。这些干燥方式干燥速度慢、成膜质量差、对外界环境因素要求高以及成本高。微波干燥水性漆与传统的干燥方式相比较，其优点在于：1)干燥速度特别快；2)不同的物质对于微波具有选择性吸收，对于被干燥物件没有形状要求；3)对于涂膜的加热很平均，不存在温度梯度，可以干燥厚膜；4)能源的利用率高，用传统的烘干设备，其能源的利用率不足50％，而用微波作为能源的利用率可达75％以上，较传统烘干设备能耗降低25％以上；5)提高工作效率，微波能够大幅加快水性漆中水分的挥发，从而避免不同气候、不同空气湿度对家具表面施工的影响。6)微波干燥后的涂膜可以立即打磨和包装处理，从而大幅缩短每道工艺所需要的时间，极大地提高了生产效率；7)安全卫生、环保，微波烘干设备无噪音、无污染、更不会产生“三废”问题。因而微波干燥更加符合需求。At present, with the rise of the domestic water-based paint coating industry, the traditional drying method is no longer enough to meet the domestic market demand and environmental protection requirements. The microwave uses high-frequency electromagnetic oscillation to make the polar water molecules in the water-based paint move and rub against each other to generate heat. , is a very promising heating method, with the advantages of fast heating and strong penetration, which can improve the drying efficiency of water-based paint coating materials and improve industrial efficiency. According to statistics, the average annual consumption of furniture in the United States is 236 US dollars, the average annual consumption of furniture in Germany is 371 US dollars, and the average annual consumption of furniture in Japan is 255 US dollars. In particular, the second- and third-tier markets and the majority of rural markets have a lower share of furniture. Chinese people who actually buy complete sets of furniture and sit on sofas are less than 400 million, which means that 2/3 of the people have not used modern furniture. This brings a huge opportunity for the further development of the furniture industry, and also makes the paint industry have great prospects. The VOCs volatile from paints include benzene, esters, aldehydes, etc., which are seriously harmful to the human body. Excessive inhalation can cause symptoms such as dizziness, chest tightness, cough, and even pleurisy, cancer, leukemia and other diseases. Figures released by the National Environmental Monitoring Center show that as many as 110,000 people die from paint poisoning each year, or an average of 304 people per day. Replacing paint with water-based paint is the trend. There are four main ways to dry traditional furniture water-based paint: natural drying, ultraviolet drying, infrared drying, and hot air drying. These drying methods have slow drying speed, poor film formation quality, high requirements on external environmental factors and high cost. Compared with traditional drying methods, microwave drying water-based paint has the following advantages: 1) The drying speed is particularly fast; 2) Different substances have selective absorption for microwaves, and there is no shape requirement for the objects to be dried; 3) Heating of the coating film Very average, there is no temperature gradient, and thick films can be dried; 4) The utilization rate of energy is high, with traditional drying equipment, the utilization rate of energy is less than 50%, while the utilization rate of microwave energy can reach more than 75% Compared with traditional drying equipment, the energy consumption is reduced by more than 25%; 5) to improve work efficiency, microwave can greatly accelerate the volatilization of water in water-based paint, thereby avoiding the impact of different climates and different air humidity on furniture surface construction. 6) The coating film after microwave drying can be polished and packaged immediately, which greatly shortens the time required for each process and greatly improves the production efficiency; 7) It is safe, hygienic and environmentally friendly. There will be no "three wastes" problem. Therefore, microwave drying is more in line with the demand.

通过上述分析，现有技术存在的问题及缺陷为：Through the above analysis, the existing problems and defects in the prior art are:

(1)目前国内水性漆涂装行业的兴起，传统的烘干方式已经不足以满足国内市场需求以及环保要求。(1) At present, with the rise of the domestic water-based paint coating industry, the traditional drying method is no longer sufficient to meet the domestic market demand and environmental protection requirements.

(2)目前国内高效环保型微波烘干设备在家具水性漆行业运用成功的案例还非常少，装机成功率非常低，采用微波干燥水性漆缺乏足够的理论指导，干燥工艺有待优化；要求水性漆微波烘干具有缜密高效的工业化流程和控制方法，以及如何去尽可能地提高干燥效率。(2) At present, there are very few successful cases of domestic high-efficiency and environmentally friendly microwave drying equipment in the furniture water-based paint industry, and the success rate of installation is very low. The use of microwave drying water-based paint lacks sufficient theoretical guidance, and the drying process needs to be optimized; water-based paint is required. Microwave drying has meticulous and efficient industrial processes and control methods, and how to improve drying efficiency as much as possible.

解决以上问题及缺陷的难度为：就目前水性漆烘干产业的起步，缺乏高效整体的烘干流程和控制系统。其水性漆微波烘干缺乏足够的理论指导，干燥工艺有待优化。The difficulty of solving the above problems and defects is: as for the current water-based paint drying industry, there is a lack of efficient and overall drying process and control system. The microwave drying of its water-based paint lacks sufficient theoretical guidance, and the drying process needs to be optimized.

解决以上问题及缺陷的意义为：The significance of solving the above problems and defects is:

(1)环境效益分析，随着环保政策的执行，以及消费者环保意识的不断提升，尤其全国各地省市出台了VOC排放限量标准，鼓励使用非溶剂型涂料，给水性漆等环保涂料的发展带来了机遇。据有关数据资料显示，2014年全国七大涂装工业重点行业所产生的VOCs总量为300万吨左右，由溶剂型木器涂料所产生的VOCs最多，达到100万吨，占七大重点行业总量的1/3。虽然目前我国木器涂料中，水性涂料比例不足10％，但从方案的要求看，这部分产品的增长在2020年之前将要求至少超过一倍。如果有50％家具企业“油改水”，可以减少44万吨VOCs排放，相当于减少了整个汽车行业的VOCs排放，而这其中包括原厂漆和修补漆。换言之整个汽车行业需要100％改用水性，才能达到50％家具企业改水的减排效果。如果有30％家具企业“油改水”，可以减少27万吨VOCs排放，等于整个汽车制造用的原厂漆100％水性化。另据中国水漆研究院统计，以2018年全国涂装市场2000万吨左右的销量计算，占比约60％的工业漆全部改用水漆，可以减少VOC排放960万吨，相当于节约1920万吨石油的消耗。(1) Analysis of environmental benefits, with the implementation of environmental protection policies and the continuous improvement of consumers' awareness of environmental protection, in particular, provinces and cities across the country have issued VOC emission limit standards to encourage the use of non-solvent coatings, water-based paints and other environmentally friendly coatings. brought opportunities. According to relevant data, in 2014, the total amount of VOCs produced by the seven key industries of the national coating industry was about 3 million tons, and the VOCs produced by solvent-based wood coatings was the largest, reaching 1 million tons, accounting for the total of the seven key industries. 1/3 of the amount. Although the proportion of water-based coatings in my country's wood coatings is less than 10%, from the requirements of the plan, the growth of this part of products will be required to at least double before 2020. If 50% of furniture companies "change oil to water", 440,000 tons of VOCs emissions can be reduced, which is equivalent to reducing the VOCs emissions of the entire automotive industry, including original paint and refinish paint. In other words, the entire automobile industry needs to be 100% water-based in order to achieve the emission reduction effect of 50% of the furniture enterprises. If 30% of furniture enterprises "change oil to water", 270,000 tons of VOCs emissions can be reduced, which is equivalent to 100% water-based original paint used in the entire automobile manufacturing. According to the statistics of China Water Paint Research Institute, based on the sales volume of about 20 million tons in the national coating market in 2018, about 60% of the industrial paints are all converted to water paint, which can reduce 9.6 million tons of VOC emissions, which is equivalent to saving 19.2 million tons. million tons of oil consumption.

(2)时间成本效益，以枫木合成板橱柜作为试验基材为例，枫木合成板橱柜整个涂层工艺流程的干燥时间，室温自然干燥时间约为5d，烘箱加热干燥时间约为9h，而使用微波加热干燥时间仅为20min，效率提高几十倍甚至几百倍。如果按烘箱加热功率40kW，每天工作8小时计算，每年工作300天，年可节省耗电约100000度/台，相当于每年减少75吨/台二氧化碳排放。同时，微波加热干燥每道工序排出的水分更多，甚至可以把前几道工序未排尽的水分排出，出现超出100％的数据，从而更能保证家具表面涂料干燥的要求。从家具表面涂料的喷涂效果也可以看出，微波干燥在快速脱水的同时并没有影响到水性漆乳液颗粒的融合、成膜，最终涂膜的性能没有受到任何影响。(2) Time and cost-effectiveness. Taking maple composite board cabinets as the test substrate as an example, the drying time of the entire coating process of maple composite board cabinets is about 5d at room temperature, and about 9h by oven heating. The drying time using microwave heating is only 20 minutes, and the efficiency is increased by dozens or even hundreds of times. If the heating power of the oven is 40kW, and it works 8 hours a day, it can work 300 days a year, and the annual power consumption can be saved by about 100,000 kWh/unit, which is equivalent to reducing carbon dioxide emissions by 75 tons/unit per year. At the same time, each process of microwave heating and drying discharges more water, and even the water that has not been exhausted in the previous processes can be discharged, and the data exceeds 100%, which can better ensure the drying requirements of furniture surface coatings. It can also be seen from the spraying effect of furniture surface coatings that microwave drying does not affect the fusion and film formation of water-based paint emulsion particles while rapidly dehydrating, and the performance of the final coating film is not affected in any way.

表1实验干燥效果对比(枫木合成板橱柜作为试验基材)Table 1 Experimental drying effect comparison (maple composite board cabinet is used as the test substrate)

由表1可以得出枫木合成板橱柜整个涂层工艺流程的干燥时间，室温自然干燥时间约为5d，烘箱加热干燥时间约为9h，而使用微波加热干燥时间仅为20min，效率提高几十倍甚至几百倍。如果按烘箱加热功率40kW，每天工作8小时计算，每年工作300天，年可节省耗电约100000度/台，相当于每年减少75吨/台二氧化碳排放。同时，微波加热干燥每道工序排出的水分更多，甚至可以把前几道工序未排尽的水分排出，出现超出100％的数据，从而更能保证家具表面涂料干燥的要求。从家具表面涂料的喷涂效果也可以看出，微波干燥在快速脱水的同时并没有影响到水性漆乳液颗粒的融合、成膜，最终涂膜的性能没有受到任何影响。From Table 1, it can be concluded that the drying time of the whole coating process of the maple composite board cabinet is about 5d at room temperature, about 9h by oven heating, and only 20min by microwave heating, and the efficiency is improved by dozens of times. times or even hundreds of times. If the heating power of the oven is 40kW, and it works 8 hours a day, it can work 300 days a year, and the annual power consumption can be saved by about 100,000 kWh/unit, which is equivalent to reducing carbon dioxide emissions by 75 tons/unit per year. At the same time, each process of microwave heating and drying discharges more water, and even the water that has not been exhausted in the previous processes can be discharged, and the data exceeds 100%, which can better ensure the drying requirements of furniture surface coatings. It can also be seen from the spraying effect of furniture surface coatings that microwave drying does not affect the fusion and film formation of water-based paint emulsion particles while rapidly dehydrating, and the performance of the final coating film is not affected in any way.

下面结合附图对本发明的技术方案作进一步的描述。The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

一、本发明的仿真方法：微波烘干是一个复杂的多物理场耦合过程，需要考虑的物理效应包含电磁场分布、流体流动、多孔介质传热以及水的蒸发，而这几种效应都是强耦合的。此模型描述了在电磁热的作用下，层流干燥气流流经含有液态水和水蒸气的多孔介质的过程，通过后处理实现对温度以及含水量变化的可视化。1. Simulation method of the present invention: Microwave drying is a complex multi-physical field coupling process, and the physical effects to be considered include electromagnetic field distribution, fluid flow, heat transfer in porous media and water evaporation, and these effects are strong coupled. This model describes the process of laminar dry air flowing through a porous medium containing liquid water and water vapor under the action of electromagnetic heat, and visualizes temperature and water content changes through post-processing.

1、在COMSOL软件，搭建图3的三维模型，模型中包含环绕放置的矩形波导、厚度为5mm正方形板材、加热腔体和进出风口四个部分。1. In the COMSOL software, build the three-dimensional model shown in Figure 3. The model includes four parts: a rectangular waveguide placed around, a square plate with a thickness of 5mm, a heating cavity and an air inlet and outlet.

2、依次添加“电磁热”中的“微波加热”(模拟空间中电场及温度场的分布)；“非等温流动”中的“层流”(模拟空间中流动场，探究流体流动对自由流动域中的温度传递)和两个“化学物质传递”中的“稀物质传递”模块(模拟液态水的蒸发过程，实现两相之间质的传递，从而研究含水量的变化)。2. Add "Microwave Heating" in "Electromagnetic Heat" (simulate the distribution of electric field and temperature field in space); "Laminar Flow" in "Non-isothermal Flow" (simulate the flow field in space, explore the effect of fluid flow on free flow) Temperature Transfer in the Domain) and two "Transport of Diluted Species" modules in "Transport of Chemical Species" (simulate the evaporation process of liquid water, realize the transfer of mass between two phases, and thus study the change of water content).

3、在多孔板材中，液相与气相同时存在，为了对多孔介质域的流体进行更好的描述，手动定义包含湿空气在内的材料属性属性。涂装板材往往呈现出外湿内干的分布，为了精确描述板材初始含水量，将板材的初始含水量设置为有关坐标的函数。以原点(0,0,0)为中心的a*a*a的板材为例，若表层含水量由内向外呈现指数变化，距表层t以下的含水量假定恒定，则含水量g可以描述为：3. In the porous plate, the liquid phase and the gas phase coexist. In order to better describe the fluid in the porous media domain, the material properties including moist air are manually defined. Coated plates often show the distribution of wet outside and dry inside. In order to accurately describe the initial water content of the plate, the initial water content of the plate is set as a function of the relevant coordinates. Taking the a*a*a plate with the origin (0,0,0) as the center as an example, if the surface water content changes exponentially from the inside to the outside, and the water content below the surface t is assumed to be constant, the water content g can be described as :

4、如图4所示，对模型域进行自由四面体网格剖分，剖分精度视模型大小而定。为了更加精确的描述涂装板材的含水量变化，对板材添加边界层，提高计算精度。4. As shown in Figure 4, perform free tetrahedral mesh division on the model domain, and the division accuracy depends on the size of the model. In order to describe the change of water content of the coated sheet more accurately, a boundary layer is added to the sheet to improve the calculation accuracy.

5、微波加热速度快、效率高，为了避免微波加热温度过高，采用间歇加热的方式，而在此过程中风机一直处于工作状态，因而采用以下计算方法来搭建整个间歇加热流程：①：研究一：选择研究步骤“频域”，频率选择2.45GHz，勾选“电磁波，频域”接口，计算空间中电磁场的分布。②：研究二：选择研究步骤“稳态”，勾选“层流”接口，计算空间中流场的速度分布。③：研究三(计算波导工作时的温度及含水量变化)：选择研究步骤“瞬态”，时间步设置为“range(0,1,60)”，勾选“固体传热”“流体传热”两个“稀物质传递”接口，求解变量的初始值采用研究一的解。④：研究四(计算波导非工作状态下温度及含水量的变化)：选择研究步骤“瞬态”，时间步设置为“range(60,1,360)”，勾选“流体传热”和两个“稀物质传递”接口，求解变量的初始值采用研究三的60s时刻的解。5. The microwave heating speed is fast and the efficiency is high. In order to avoid the microwave heating temperature being too high, the intermittent heating method is adopted. During this process, the fan is always working. Therefore, the following calculation methods are used to build the entire intermittent heating process: ①: Research 1: Select the research step "Frequency Domain", select 2.45GHz as the frequency, check the "Electromagnetic Wave, Frequency Domain" interface, and calculate the distribution of the electromagnetic field in space. ②: Study 2: Select the study step "Steady State", check the "Laminar Flow" interface, and calculate the velocity distribution of the flow field in space. ③: Study 3 (Calculate the temperature and water content changes when the waveguide is working): Select the study step "Transient", the time step is set to "range(0,1,60)", check "Solid Heat Transfer" and "Fluid Transfer". Heat" two "Transport of Diluted Species" interfaces, the initial values of the solution variables are the solutions fromStudy 1. ④: Study 4 (calculate the change of temperature and water content in the non-working state of the waveguide): select the study step "transient", the time step is set to "range(60,1,360)", check "fluid heat transfer" and two In the "Transport of Diluted Species" interface, the initial value of the solution variable adopts the solution at the time of 60s in study three.

6、结果后处理。通过添加三维绘图组可以很容易的看出温度的分布状态；而含水量可以通过W＝Mn_l*cl/rho_p来描述，其中Mn_l为每摩尔液态水的分子量、cl为多孔介质板材中液态水的浓度、rho_p为多孔板材基体的密度。温度跟含水量随时间的变化曲线通过添加派生值(体平均值)方法来进行绘制。0-50s内板材表面的温度分布状态：如图5(a)-图5(f)。流场的速度分布，如图6所示。6. Post-processing of results. The temperature distribution can be easily seen by adding a three-dimensional drawing group; and the water content can be described by W=Mn_l*cl/rho_p, where Mn_l is the molecular weight per mole of liquid water, and cl is the liquid water in the porous media plate. The concentration and rho_p are the density of the porous plate matrix. The curve of temperature versus water content over time was plotted by adding a derived value (volume average) method. The temperature distribution state of the plate surface within 0-50s: as shown in Figure 5(a)-Figure 5(f). The velocity distribution of the flow field is shown in Figure 6.

二、优化方法：2. Optimization method:

1、网格的剖分：对于涂装产品而言，被烘干物件的内外含水量是有明显差异的，烘干最剧烈的部位往往发生在物料的外表面，因而，为了提高仿真精度，需对物料的外表面进行高精度的网格剖分：以厚度为5mm的正方形板料为例，在网格剖分的基础上，添加边界层网格，边界层的厚度根据实际外表含水层情况而定，边界层应当略厚与实际外部涂装含水层。如图7所示。1. Mesh division: For coated products, the moisture content inside and outside the object to be dried is obviously different, and the most severe drying part often occurs on the outer surface of the material. Therefore, in order to improve the simulation accuracy, It is necessary to perform high-precision mesh division on the outer surface of the material: take a square sheet with a thickness of 5mm as an example, on the basis of mesh division, add a boundary layer mesh, and the thickness of the boundary layer is based on the actual surface aquifer. Depending on the situation, the boundary layer should be slightly thicker than the actual outer coated aquifer. As shown in Figure 7.

2、波导管的位置优化：2. Position optimization of waveguide:

微波加热具有加热不均匀的缺陷，这是由于分布在空间中的电场不均匀所致，而这种不均匀的特性从根本上是无法消除的，只能通过各种方式进行缓解。对于多溃口激励的微波谐振腔体，溃口位置对电场分布有很大的影响。通过调整波导管的位置可以在很大程度上缓解空间中电场的不均匀特性。如图8(a)-图8(d)。Microwave heating has the defect of non-uniform heating, which is caused by the non-uniform electric field distributed in the space, and this non-uniform characteristic cannot be eliminated fundamentally, and can only be alleviated in various ways. For a microwave resonator cavity excited by multiple fractures, the position of the fractures has a great influence on the electric field distribution. The non-uniformity of the electric field in space can be largely alleviated by adjusting the position of the waveguide. Figure 8(a)-Figure 8(d).

在上述的对比仿真中不难发现，在空间中呈中心旋转对称的波导放置方法，并且错开相对的波导方向，会在很大程度上改善电场的不均匀性。In the above comparative simulation, it is not difficult to find that the waveguide placement method that is rotationally symmetric in the space and staggers the relative waveguide directions will greatly improve the non-uniformity of the electric field.

3、波导功率及间歇时间的改善。不同物料的材料属性不同，耐热性能是不一样的，过高的温度会导致被加热物产生翘边等现象，因此需对不同的加热物设置不同的功率相应的间歇时间来及时散热，并通过流体流动带走箱体内部的湿空气。3. Improvement of waveguide power and intermittent time. The material properties of different materials are different, and the heat resistance performance is different. Excessive temperature will cause the heated object to warp and other phenomena. Therefore, it is necessary to set different power and corresponding intermittent time for different heating objects to dissipate heat in time. The moist air inside the box is carried away by the fluid flow.

选取物料加热时间为设计变量，物料烘干的优化模型为：The material heating time is selected as the design variable, and the optimization model of material drying is:

Min.g(含水量)Min.g (water content)

s.t. T(max)<A，T(end)<Bs.t. T(max)<A, T(end)<B

Time(总)＝CTime(Total)=C

优化目标是在C时间段内，保证物料最高温度不超过A，最终冷却温度不高于B的情况下，通过调整加热时间，使得物料的含水量g最小。如图9所示。The optimization goal is to ensure that the maximum temperature of the material does not exceed A and the final cooling temperature is not higher than B within the C period, and the water content g of the material can be minimized by adjusting the heating time. As shown in Figure 9.

以被加热板材不被破坏可承受的最高温度为95℃，冷却后温度不高于70℃，总时间为350s为例，如图10所示。Take the maximum temperature that the heated sheet can withstand without being damaged as 95°C, the temperature after cooling is not higher than 70°C, and the total time is 350s, as shown in Figure 10.

表1Table 1

加热时间(s)Heating time (s)30303535404045455050最高温度(℃)Maximum temperature (℃)68.368.374.574.581.681.685.985.994.794.7冷却后的温度(℃)Temperature after cooling (℃)41.341.353.153.162.662.672.472.483.783.7含水量(％)Moisture content (%)24.524.524.1524.1523.8523.8523.423.423twenty three

可以看出，在满足工艺T(max)<A，T(end)<B的情况下，加热40s的效果最好。It can be seen that under the condition that the process T(max)<A and T(end)<B are satisfied, the effect of heating for 40s is the best.
