Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of corn seed machining production line as shown in Figure 1; comprise drying plant connected successively, thresing machine, air-and-screen cleaner, proportion type cleaning plant, dressing drying integral machine, film forming storehouse and weighing and bagging machine; it is characterized in that; also be provided with pre-heating cabin between described proportion type cleaning plant and dressing drying integral machine, described drying plant is solar drying device.As shown in Figure 2, solar drying device comprises the closed circulation pipeline of solar energy heating unit 11, storage heater 12, delivery pump 15, warehouse for drying 14 and heat exchanger 13 composition connected by pipeline; Liquid heat transfer medium is filled with in storage heater 12; The main air duct that warehouse for drying 14 comprises its inside and point air channel be communicated with main air duct; Main air duct is provided with dries blower fan 17; Heat exchanger 13 is arranged on main air duct; The outside side of warehouse for drying 14 is provided with exhaust outlet, and opposite side is provided with air inlet, is provided with U-shaped material transport mechanism 16 in warehouse for drying 14.Solar energy heating unit 11 is made up of some solar thermal collectors be connected in parallel.Material transport mechanism 16 is conveyer belt or transfer roller, and this conveyer belt or transfer roller are through main air duct 41 and divide air channel 42, to form tunnel type drying line.The line track body of this material transport mechanism is U-rail, connects, stable and reliable operation with flange plate and screw.If power set, tensioning apparatus, anti-skidding adhesive tape, driven gear, connect lubricating cup, hook etc., stable, speed 0.5-3m/min is adjustable.Dehydrating unit and attemperating unit is also provided with in baking room.As shown in Figure 3, pre-heating cabin comprises the warehouse 23 be arranged in frame 21, and warehouse 23 top is provided with charging aperture 25, and bottom is provided with discharging opening 22, warehouse 23 outer circumferential walls is provided with many hot blast manifolds 24 passing into warehouse 23 inside, and be interconnected between each hot blast manifold 24 hot-blast main 26; Hot-blast main 26 inside is provided with many group electric heaters 27, and its bottom is connected with the air outlet of air blast 28; Warehouse 23 center of inside is provided with agitating device 29.Wherein electric heater 27 is preferably dry combustion method electrothermal tube, has three groups at least; Heat insulation protection cover is provided with between this electric heater 27 and pipeline.Warehouse 23 inwall is provided with Anti-Adherence Coating of Polytetrafluoroethylene, prevents material sticks within it on wall.
The course of work of the present utility model is: corn first carries out drying by drying plant, enters the corn seed particle that thresing machine threshing obtains.Corn seed particle through air-and-screen cleaner and proportion type cleaning plant clean classification after enter preheating in pre-heating cabin, after preheating in dressing drying integral machine dressing, enter the film forming storage of film forming storehouse after dressing completes, enter weighing and bagging machine after film forming completes and obtain final product.When use solar drying device corn is dried time, as shown in Figure 2, the liquid thermal conductivity media in solar energy heating unit 11 pairs of pipelines heats, delivery pump 15 work make heat-conducting medium by Pipeline transport to heat exchanger 13 for hyperthermia drying.Exhaustless heat-conducting medium is got up to storage heater 12 li of deposits by Pipeline transport, in sun deficiency or when working at night, heat-conducting medium for subsequent use in recycling fluid reservoir, if now the heat-conducting medium temperature of 12 li, storage heater does not reach necessary requirement, assisted heating device is started by control device, post bake is carried out to heat-conducting medium, finally reaches baking needed temperature.During drying work, when corn to be dried is after entering warehouse for drying 14 by driving-belt, advance with the speed of 0.5-3m/min, corn is carried out twice oven dry back and forth with the temperature of setting.Specifically: cold wind enters from air inlet, dry blower fan 17 transporting cold wind and carry out heat exchange from main air duct through heat exchanger 13, heat exchanger 13 is heated to the air flowed through, make it to become dry hot blast, hot blast is diverted to crisscross point air channel from main air duct again, and in warehouse for drying 14, the corn material on conveyer belt is dried, hot blast after oven dry is discharged by exhaust outlet, completes the process of Hot-blast Heating circulation.Before seed pelleting, pre-heating cabin is utilized to carry out preheating, as shown in Figure 3, open air blast 28 and electric heater 27, hot blast is carried out drying by material gap along hot-blast main 26 and each hot blast manifold 24 and heats up by the heat that electric heater 27 produces, make the moving air having higher temperature in warehouse 23, by the impact of this hot-air, in warehouse 23, the temperature of corn seed raises, start agitating device 29 simultaneously to the heating of material limit, limit is stirred, and all seeds are contacted with thermal current simultaneously, prevent seed to be sticked together, pre-heat effect is better.After material moisture drying by discharging opening discharge for.This seed flowed out from warehouse 23 enters seed-coating machine when carrying out dressing, and coating agent just can be attached to heating seed surface better, thus substantially increases coating effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
