Method and device for dehulling separation of flax seed

Abstract

Disclosed is a method for flax seeds decortication and separation, comprising dehydrading flax seeds to a moisture percentage of 2-4%; feeding same into a rotary centrifugal decortication machine continuously, decorticating the flax seeds to form a mixture of shells and kernels; and separating the shells and kernels mixture through an electrostatic field. An apparatus realizing said method comprises a centrifugal decortication machine, screen means mounted on the discharge side of the centrifugal decortication machine, a convey belt mounted on the discharge side of the screen, and electrostatic absorption means mounted over the discharge terminal of the convey belt front part. The method is provided with continuously industrialization production for large amounts of product, complete seperation of shells and kernels, and high production efficiency to shorten the art time from the flax seeds feeding, decorticating to discharging by 80%, decrease full cost by 50%, and produce no environmental waste materials.

Description

technical field [0001] The invention relates to a method and related equipment for peeling and separating seeds and skins of crop fruits, which are applicable to the peeling of linseed or similar crop fruits and the method and equipment for separating kernels and skins. Background technique [0002] Flaxseed is the fruit of an oil crop. The oil content in the grain is very high, and the oil contains about 48% σ-linolenic acid, which has the highest α-linolenic acid content in bulk oil crops. Containing about 10% linseed gum in the hull, it is the only vegetable gum resource available in oil crops. Flax bark contains a large amount of flax lignans, as a kind of phytoestrogens, its content is about 800 times that of other crops. So far, the processing and utilization of the above-mentioned beneficial ingredients have all been carried out without peeling or effective separation of seeds and skins. Therefore, the yield of above-mentioned various beneficial ingredients is very...

AI Technical Summary

Problems solved by technology

This method of separation is too complex and difficult to control

First of all, flaxseeds are constantly rubbed and squeezed in the separation chamber, and the oil in the husked kernels will overflow, causing adhesion between the husks or between the husks and the kernels, making it difficult to separate further

In addition, it is difficult to control the flow rate of flaxseed in the separation chamber by sending air into the separation chamber, especially in the case of oil adhesion.

Third, the separation purity is not high by using screen plus gravity separation, and further separation measures are usually required

Fourth, due to the use of the above more complicated method, the separation equipment is also more complicated
