Problems solved by technology

[0005] 1. The pretreatment process of traditional rapeseed oil production and the current pretreatment process of rapeseed extrusion puffing oil at home and abroad are relatively complicated and require more equipment
[0006] 2. The steaming and extrusion temperature of rapeseed oil pretreatment process is relatively high (100°C-160°C), and the degree of protein denaturation is relatively large, which reduces the later utilization value of protein in rapeseed meal
[0007] 3. At present, the sleeves and press cages of the extruding devices with high oil content (such as rapeseed) at home and abroad are integral structures. The disadvantage is that the screws and sleeves inside the extruder are not clean, adjusted, and convenient

Embodiment Construction

[0016] specific implementation

[0017] Embodiments of the present invention: Below in conjunction with the accompanying drawings, the implementation of the present invention will be further described.

[0018]After the rapeseed is cleaned, if its water content is higher than 10%, it is dried at low temperature to make its water content ≤ 10%, and then crushed or shelled with shells to obtain rapeseed kernels with a shell content of ≤ 5%. Crushed shells (with a particle size of 0.6mm~1.0mm) or shelled rapeseed kernels enter the extrusion device through the feeding port 3 (see the attached picture). The outer surface of the three-section screw 8, the fourth-section screw 13 and the first sleeve 2, the second sleeve 4, the third sleeve 5, the first squeeze cage 7, the second squeeze cage 9, the first squeeze cage In the extrusion chamber formed by the inner surface of the four-section sleeve 10, the main shaft 22, the first section screw 1, the second section screw 6, the third...

Abstract

The invention relates to rape seed making oil technical field, which is a rape seed extruding processing method and equipment in the procession of making oil. Its main technical characteristic is that the best parameters of rape seed extruding device and press processing system are supplied, making the remainder rate is not larger then 1.3%, without the steps and equipments of softening, squeezing and cooking in conventional processing technique, the steps and equipments of softening, squeezing, injecting steam and cooling water into the extruded material and drying in the preprocessing technique of extruding in nation and abroad, and that of cold squeezing and injecting steam into the extruded material, which makes rape seed stay shorter in pressing cavity, the pressing temperature is not higher then 80-110deg.C, the level of protein degeneration is low, the quality of oil is grad, the an of protein in rape seed is high and each sleeve and of extruding device can be separated along the animal direction.

Description

technical field [0001] The invention belongs to the technical field of a rapeseed processing method and a processing device in the pretreatment process of extracting rapeseed oil. technical background [0002] The pretreatment process of traditional rapeseed oil production is: rapeseed cleaning - softening - pressing germ - steaming - pressing or pre-pressing, leaching. At present, the pretreatment process of rapeseed extruded puffed soaking oil at home and abroad is: rapeseed cleaning - (drying - cooling) - peeling (or not peeling) - softening - pressing germ - steaming - puffing - leaching (Lusas E.W and Watkins L.R. .Oilseed Extrusion for SolventExtraction.
