Description

A kind of method and apparatus of wet concentration washing rapeseed

One, technical field: the invention belongs to the foodstuff processing technology field, particularly a kind of method and apparatus that is used for the wet concentration washing rapeseed of rapeseed processing.

Two, technical background: at present in the processing of rapeseed, the rapeseed after main employing will gather in the crops is carried out direct method for processing oil expression, and contains a large amount of rotten, immature rapeseed and impurity such as sandy soil and stalk of going mouldy inside these rapeseed; Test after deliberation; These content that go mouldy rotten, immature rapeseed and impurity such as sandy soil and stalk account for the 15-25% of rapeseed total amount, and they are not removed when oil expression and extract oil in the lump with rapeseed, like this; It will reduce the quality and the quality of rapeseed oil widely; The edible low rapeseed oil of these qualities of people can have a strong impact on people's health, and so, why not people handle these rapeseed; Its reason is: the one, and the processor is in order to save trouble; Be reluctant that infusion of financial resources carries out scientific research and deal with problems, people are edible for a long time and forms the habit, and people are not enough to its recognizing dangers; The 2nd, these contain and also become rapeseed cake after go mouldy rotten, immature rapeseed and impurity such as sandy soil and stalk are extracted oil, and can also sell for money.Therefore in the processing of rapeseed, how removing these go mouldy rotten, immature rapeseed and impurity such as sandy soil and stalk is people's difficult problems anxious to be solved.

Three, summary of the invention:

The objective of the invention is to the above-mentioned deficiency that exists in the prior art, and develop the method and apparatus that a kind of wet concentration is washed rapeseed, the method and apparatus of this wet concentration washing rapeseed can effectively overcome the deficiency of prior art; It has easy to use, and floor space is little, can effectively remove go mouldy rotten, immature rapeseed and impurity such as sandy soil and stalk in the rapeseed; Can improve the quality and the quality of rapeseed oil greatly; Its equipment design is ingenious, and cost is low, installation, use, easy to maintenance; Can the water consumption consumption lack, have good economic and social benefit.

Technical scheme of the present invention is: the technical characterictic of the method for wet concentration washing rapeseed of the present invention is; Adopting water to the rapeseed of oil expression to be processed is that medium carries out wet concentration; With going mouldy of removing that rapeseed the inside contains rotten, immature rapeseed and stalk impurity; Adopting water to the rapeseed of oil expression to be processed is that medium is washed, and to remove sandy soil and the water-soluble impurity that the rapeseed the inside is contained, wet concentration washing rapeseed adopts the method for machinery to realize.Water should be the water of clean cleaning, and water has on earth everywhere, and distributed pole is wide, and it is good and cheap, uses it can reduce the processing charges of rapeseed greatly as medium.The go mouldy proportion of rotten, immature rapeseed and stalk impurity is little because rapeseed the inside is contained; It is bubbled through the water column when wet concentration; Adopt machinery to be easy to remove; And sandy soil and water-soluble impurity that the rapeseed the inside is contained all can adopt the mode of washing to remove, and this water-washing method adopts machinery also to realize easily.

The technical characterictic of the equipment of wet concentration washing rapeseed of the present invention is; This equipment by shell body, laterally wash spiral agitator, vertically wash discharging spiral agitator, discharging screen drum, grains of sand spiral remover five parts and form; Laterally the washing spiral agitator is made up of motor and deceleration component, spiral agitator two parts; Vertically washing discharging spiral agitator is made up of motor and deceleration component, helical stir parts two parts; Also be provided with charging aperture, vegetable seed outlet, regulating water level mouth, grains of sand outlet, the additional mouth of clean water on the shell body; Laterally the assembly of washing spiral agitator, grains of sand spiral remover, discharging screen drum three parts is packed on the shell body, and the assembly that vertically washs the discharging spiral agitator is packed on the shell body, and its helical stir parts place in the discharging screen drum.Shell body is the casing of wet concentration washing rapeseed equipment, and it is the place of wet concentration washing, is again the element that installs each parts.Laterally the washing spiral agitator is that the rapeseed of treating the wet concentration washing is stirred the device of wet concentration washing; It is made up of motor and deceleration component, spiral agitator two parts; Can establish a spiral agitator in every equipment; Also can establish two or more spiral agitators, the power of spiral agitator is provided by motor and deceleration component.Vertically washing discharging spiral agitator is with the device that carries out separating and dehydrating that laterally washs after spiral agitator carries out the wet concentration washing; It is made up of motor and deceleration component, helical stir parts two parts, and the power of helical stir parts is provided by motor and deceleration component.The discharging screen drum is under the effect of helical stir parts, to make water and rapeseed carry out the separating and dehydrating parts, has been covered with sieve aperture around it, and sieve aperture can leach water outside the discharging screen drum, and rapeseed is then stayed in the discharging screen drum.Grains of sand spiral remover is located at the bottom in the shell body, and the grains of sand after will wash in the use carry out the device regularly cleared up, and it can adopt mechanical system, also can adopt the structure of manual mode.

In the use; The rapeseed of treating the wet concentration washing gets into from charging aperture; Clean water is replenished mouth from clean water and is input in the shell body and mixes with the rapeseed of treating the wet concentration washing, and water and rapeseed are rotated under the stirring at the horizontal spiral agitator of washing spiral agitator and carried out wet concentration and washing, and rotten going mouldy in the wet concentration, immature rapeseed and stalk impurity are removed from the regulating water level mouth; Remove sandy soil and water-soluble impurity again in the washing; Sewage after the washing also can be recycled, and the rapeseed after the wet concentration washing is pulled to the bottom of discharging screen drum and piles up under the spiral agitator rotation is stirred, upwards be promoted to the vegetable seed exit by the rotation of the helical stir parts in the discharging screen drum again and discharge the clean oil vegetable seed that obtains containing certain moisture; These clean oil vegetable seed just can be processed oil expression, just can improve the quality of rapeseed oil greatly.

The present invention has following advantage:

(1) method of wet concentration washing rapeseed of the present invention can effectively overcome the deficiency of prior art; It has easy to use; Floor space is little, can effectively remove go mouldy rotten, immature rapeseed and impurity such as sandy soil and stalk in the rapeseed, can improve the quality and the quality of rapeseed oil greatly.

(2) equipment design provided by the invention is ingenious, and cost is low, and installation, use, easy to maintenance can the water consumption consumption be lacked, and have good economic and social benefit.
