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
The present invention relates to the method that plant seed shells, the method for peeling off of the linseed oil of more specifically saying so, sand sagebrush (Artemisia filifolia) seed.Kind of shell is separated with kernel (being kind of a benevolence again), obtain purified kernel.Be convenient to next step and extract vegetable jelly contained in these seeds and/or vegetables oil.
(2) background technology
How needed vegetable jelly and/or vegetables oil are from plant seed in the modern industry, particularly foodstuffs industry, and its method of producing adopts water extraction or organic solvent extraction more, but production cost is higher, complex process.Prior art is that the mechanical means of physics separates shell with kernel, and this method makes the kernel loss more, and colloid purity is not high.Do not see in the document as yet with the plant seed of chemical treatment band shell technology in conjunction with physical method separating husk and seed.
(3) summary of the invention
Purpose of the present invention just is to work out a kind of suitability for industrialized production that adapts to, simple, the plant seed of being convenient to grasp is the method for stripping shell of linseed oil, sand sagebrush (Artemisia filifolia) seed for example, peels off in this way to obtain producing the high-quality raw material of vegetable jelly and/or vegetables oil.
The method for stripping shell of a kind of plant seed of the present invention, with the plant seed through pretreated band shell is raw material, under 10-60 ℃ of temperature, will be immersed in the soak solution that organic solvent and oxygenant form after 1-60 minute with the plant seed of shell, emit soak solution, or under 10-60 ℃ of temperature, it is carried out 1-40 minute spray, the plant seed control of band shell is done, with 50-90 ℃ dry-heat air the plant seed baking of band shell is blown, make its drying, peel off with the mechanical means of physics again, will be with the shell of the plant seed of shell to separate with kernel.
The plant seed of said band shell with linseed oil, a sand sagebrush (Artemisia filifolia) seed seed wherein for well.Said pre-treatment is exactly that for example linseed oil, sand sagebrush (Artemisia filifolia) seed carry out pneumatic jig choosing to the plant seed of band shell with commercially available built-up type seed cleaner, use commercially available specific-gravity stoner (being the classification stone remover again) to carry out further selected then, remove the handstone in the seed, to form purity be that the seed of 98-99% is as raw material to the dust of removing the surface with commercially available polishing dusting machine again.For as the band shell plant seed of raw material for example the purity of linseed oil, sand sagebrush (Artemisia filifolia) seed further improve, for example linseed oil, sand sagebrush (Artemisia filifolia) seed are put into 40-60 purpose basket with the band shell plant seed of purity 98-99%, aqueous ethanolic solution with percent by volume 90-95% carries out drip washing as leacheate, the amount of the aqueous ethanolic solution of used leacheate percent by volume 90-95% be as the vegetation zone shell seed of raw material for example linseed oil, sand sagebrush (Artemisia filifolia) seed 50～100%.Like this, can further remove the dust impurity that sticks on the seed.Centrifuge dripping after the drip washing forms the linseed oil of purity more than 99.9%, sand sagebrush (Artemisia filifolia) seed as raw material.The oil of making as raw material with the linseed oil of high purity, sand sagebrush (Artemisia filifolia) seed and/or the purity height of glue.The exhausted leacheate can reclaim purification, uses again.
Will be under 10-60 ℃ temperature through pretreated linseed oil, sand sagebrush (Artemisia filifolia) seed, in the soak solution that organic solvent and oxygenant are formed, soaked 1-60 minute, again to soak 5-30 minute for well, the time of its immersion changes with the temperature of soaking, the temperature height of immersion, and the time of immersion just can shorten, the temperature of soaking is low, and the time of immersion will prolong.
Can also be to linseed oil, sand sagebrush (Artemisia filifolia) seed at 10-60 ℃ of spray that carries out 1-40 minute.Said spray is exactly in reactor or on the travelling belt, its seed is carried out 1-40 minute spray under 10-60 ℃ temperature, and spray plays the effect of immersion equally.The effect of soaking or spraying is that seed absorbs soak solution or spray liquid, carry out preliminary chemical reaction, realize the reactions change of seed internal structure, the consumption of soak solution or spray liquid is for being with for example 100-200% of linseed oil, sand sagebrush (Artemisia filifolia) seed volume of shell plant seed volume when soaking or spray, and exhausted soak solution or spray liquid can recycling uses.
Said soak solution or spray liquid are made up of organic solvent and oxygenant.Said organic solvent is wherein a kind of of ethanol, ethylene glycol, acetone, sherwood oil, is good with ethanol again.Said oxygenant is wherein a kind of of hydrogen peroxide, hypochlorous acid, is advisable with hydrogen peroxide again.Soak solution or spray liquid more account for percent by volume the best that 2-10% is consisted of with the hydrogen peroxide that the ethanol of concentration 90-95% weight percentage accounts for percent by volume 90-98% and concentration 10-30% weight percentage.
After for example linseed oil, the control of sand sagebrush (Artemisia filifolia) seed were done with the plant seed of band shell, the band shell plant seed that control is done for example linseed oil, sand sagebrush (Artemisia filifolia) seed dried by the fire the plant seed of band shell with 50-90 ℃ dry-heat air and to blow 5-30 minute in fluidized bed dryer or other moisture eliminator.This process is the inner process that produces chemical reaction of seed, the inner gas that produces of seed in this process makes seed be expanded to about a times of original volume, and the seed of this moment still is kept perfectly, separate fully with kernel (being kind of a benevolence again) but plant shell, form a cavity.Baking dry up dry after, plant shell and become fragile, again with the mechanical means of physics for example physical mechanical methods such as seed decorticator, rice milling machine, vibrating pulverizer peel off, finish thorough separation of seed shell and kernel (kind benevolence), and kernel is kept perfectly.
The advantage of the method for stripping shell of a kind of plant seed of the present invention just is:
1. the technology of peeling off of seed that contains glue and/or oil of the present invention is simple, easy handling, and production cost is low, can reduce the production cost of later stage product (oil and/or glue) again, improved the quality of later stage product, the loss of kernel (kind benevolence) is few, is a kind of brand-new technology.
2. method facility investment of the present invention is few, the saving of labor, saves time production efficiency height, method uniqueness.
3. method of the present invention no waste discharging in process of production, free from environmental pollution, have good social benefit.
