Embodiment 1

[0027] Embodiment 1 200 kilograms of flax seeds are dried to a moisture content of 4%, and are sent into a centrifugal peeling machine at a speed of 2 kilograms per minute. The radius of the accelerating drum 4 is 15 cm, and the height is 50 cm. A circular hole with a diameter of 12mm, and the rotating speed of the drum is 2500 rpm. The shell radius of centrifugal peeling machine is 50cm. The peeling rate reaches 60%. The upper screen of the screen equipment is 12 mesh, and the lower screen is 36 mesh. Electrostatic roller voltage 8000 volts. The separation rate of shell skin and kernel is 97%.

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 σ-linolenic acid content in bulk oil crops. The husk contains about 8% flax glue, which is the only vegetable glue resource available in oil crops. Flax cake 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 low...
