Problems solved by technology

[0002] Most of the vegetable gums and / or vegetable oils needed in modern industry, especially the food industry, come from plant seeds, and the methods for their preparation mostly use water extraction or organic solvent extraction, but the production cost is high and the process is complicated
The existing technology is to separate the shell from the nucleolus by a physical mechanical method. This method causes a lot of loss of the nucleolus and the purity of the colloid is not high
The process of chemically treating shelled plant seeds combined with physical methods to separate shells and seeds has not been found in the literature

Embodiment 1

[0016] Pretreatment of artemisia seeds:

[0017] The Artemisia annua seeds are first aired and screened with a commercially available combined seed cleaning machine, and then further selected with a commercially available grading specific gravity destoner to remove the small stones in the Artemisia annua seeds, and then polished to remove them. The dust machine removes the dust on the surface of Artemisia annua seeds to form Artemisia annua seeds with a purity of 99%, and finally put the Artemisia artemisia seeds with a purity of 99% into a 50-mesh sieve basket, and use ethanol with a volume percentage of 95% as the eluent. Artemisia artemisiae seeds are rinsed, and the amount of the used eluent is 100% of the weight of Artemisia artemisiae seeds, and the artemisia artemisiae seeds after rinsing are centrifugally dried, so that the impurities adhered on the Artemisia artemisiae seeds are removed to form Artemisia seeds with a purity of 99.9%.

Embodiment 2

[0020] Its method of operation and equipment are basically the same as in Example 1, except that 100 kilograms of pretreated linseeds are mixed with 98 percent by volume ethanol of 95 percent by weight and 98 percent by volume of hydrogen peroxide with a concentration of 30 percent by weight. The soaking liquid formed with a percentage of 2% was soaked at 25°C for 30 minutes, and the amount of the soaking liquid used was 150% of the volume of the linseed. Feed 90 DEG C of dry hot air into the fluidized bed drier for 15 minutes to dry the linseed completely, then use a commercially available seed sheller to separate 38 kg of seed shells and 62 kg of seed kernels.

Embodiment 3

[0022] Its method of operation and equipment are basically the same as in Example 1, except that the soaking solution that accounts for 98% by volume of ethanol with a concentration of 90% by weight and 2% by volume of hydrogen peroxide with a concentration of 10% by weight is used at 10° C. Soak for 60 minutes, the amount of soaking liquid used is 100% of the volume of Artemisia annua seeds, and dry hot air at 50° C. is fed for 30 minutes.

Abstract

A process for stripping the shell of plant seed (flax seed or sand artemisia seed) includes pretreating, immersing in liquid, dripdrying, backing by hot air at 50-90 deg.C and physically separating shell from kernel. Its advantages are less loss of kernel, and no environmental pollution.

Description

(1) Technical field [0001] The invention relates to a method for shelling plant seeds, more specifically a method for shelling linseeds and artemisia seeds. In this way, the seed shell is separated from the nucleolus (also known as the seed kernel) to obtain pure nucleolus. Facilitate the next step of extracting the vegetable gums and / or vegetable oils contained in these seeds. (2) Background technology [0002] Most of the vegetable gums and / or vegetable oils needed in modern industry, especially in the food industry, come from plant seeds, and the methods for their preparation mostly use water extraction or organic solvent extraction, but the production cost is high and the process is complicated. In the prior art, the shell and the nucleolus are separated by a physical mechanical method. This method causes a large loss of the nucleolus and the purity of the colloid is not high. The process of chemically treating shelled plant seeds combined with physical methods to sepa...
