Embodiment 1

[0026] refer to Figure 1-5 , a flaxseed peeling process is characterized in that comprising the following steps:

[0027] A. Place the flaxseed in the frying pan 1, heat to 105°C, and stir evenly for 20 minutes;

[0028] B. The frying pan 1 is connected to the peeling mechanism 3 through the conveying pipe 2, and the flaxseed is transported to the peeling mechanism 3 through the conveying pipe 2, and the peeling mechanism 3 performs peeling treatment on the flaxseed, and uses dry ice to cool the flaxseed during the process;

[0029] C, a vibrating screen 4 is arranged below the peeling mechanism 3, a heating wire 5 is arranged in the vibrating screen 4, a filter screen 6 is arranged below the vibrating screen 4, and a negative pressure fan 7 is connected to the outside of the filter screen 6; flaxseed passes through the peeling mechanism 3 After treatment, it falls onto the vibrating screen 4, and the vibrating screen 4 is heated to 75°C to separate the linseed kernels and l...

Embodiment 2

[0037] refer to Image 6 , This embodiment is improved on the basis of Embodiment 1. Bearings 33 are movably installed on both sides of the installation groove 20 through springs 32 , and the rotating shaft 21 is installed in the bearings 33 . The up and down movement of the pressure roller 22 can be realized by movably installing the rotating shaft 21 . Therefore, the arc-shaped groove 23 on the surface of the pressing roller 22 can make the linseed enter into the gap between the pressing roller 22 and the installation groove 20 to be squeezed and crushed, thereby further improving the peeling rate of the linseed. Use the flaxseed identical with embodiment 1 to carry out comparative test:

[0039]

Embodiment 3

[0041]This embodiment is improved on the basis of embodiment 2, and the air output of the negative pressure fan is controlled at 90% of the air intake of the compressed air pipe. Through this setting, the vibrating screen 4 can be in a positive pressure state, and the turbulence of the air flow can be used to improve the floating separation effect of the linseed skin, thereby improving the separation efficiency of the husk and kernel. Use the flaxseed identical with embodiment 2 to carry out comparative test:

Abstract

The invention discloses a linseed dehulling process. The linseed dehulling process comprises the following steps that A, linseeds are put into a wok, heated to 100-105 DEG C and evenly mixed for 20 min; B, the wok is connected to a dehulling mechanism through a delivery pipe, the linseeds are conveyed to the dehulling mechanism through the delivery pipe, and the linseeds are subjected to dehullingtreatment through the dehulling mechanism and are cooled through dry ice in the treatment process; C, a vibrating screen is arranged below the dehulling mechanism, a heating wire is arranged in the vibrating screen, a filter screen is arranged below the vibrating screen, and the outer side of the filter screen is connected with a negative-pressure fan; the linseeds fall onto the vibrating screenafter being treated through the dehulling mechanism, the vibrating screen is heated to 70-80 DEG C, linseed kernels and linseed hulls are separated, the linseed kernels are retained on the vibrating screen, and the linseed hulls pass through the vibrating screen under the suction action of the negative-pressure fan and are finally gathered onto the filter screen. Through the linseed dehulling process, the defects in the prior art can be overcome, and the separation degree of linseed hulls and kernels is further improved.

Description

technical field [0001] The invention relates to the technical field of linseed finishing, in particular to a linseed peeling process. Background technique [0002] Studies have shown that flaxseed contains a variety of large amounts of nutrients or active ingredients, such as linolenic acid, flax gum, lignans, flax protein, dietary fiber, etc. Then, most of the ingredients are distributed in the linseed kernel or linseed husk. The traditional production method is to extract oil from linseed, and then use the linseed cake after oil extraction as animal feed or to extract other substances. The advantage of this process is that it is easy to operate, but the disadvantage is that a lot of active ingredients are wasted, which increases the difficulty of extraction. and cost. Therefore, for many years, in order to change the traditional raw tea process and improve the value of comprehensive utilization of flax, many people have tried to separate the kernel and skin of flaxseed. ...
