Abstract
The present invention relates to a coated (laminated) choline hydroxide or salt thereof and coating technology, which belongs to choline hydroxide as a chemical product or salt thereof and post-treatment technology for the choline hydroxide or salt thereof. Choline hydroxide or salt thereof is laminated and coated to form coated and laminated choline hydroxide or salt thereof. Film forming technology comprises: firstly, after being weighed, choline hydroxide or salt thereof is poured into a laminating machine, and the material temperature is controlled to be from 40 to 70 DEG C; secondly, an air compressor is started, pressure is controlled, and a high pressure spray gun is utilized to spray film forming agents on the crystal surfaces of the choline hydroxide or the salt thereof; the material temperature is controlled, and the material is continuously heated to be dried by hot air; after 30 minutes, the air compressor is stopped, and the material is discharged, sieved and packaged; thirdly, the film forming agent is prepared by that nontoxic film material is dissolved in solvent to obtain uniform film liquid, and the concentration is from 1% to 10%; finally, after being coated, the weights of products are increased by 0.5% to 5% according to different requirements of different products. The technology is suitable for coating and laminating choline hydroxide or salt thereof.
Description
Affiliated field
The present invention relates to Chemicals choline or its salt, and the post-processed technology of choline or its salt.
Background technology
Choline belongs to vitamin B group, has the promotion growth of animal, keeps metabolism of fat and liver function normally to wait effect.The kind of its salt has choline chloride 60, choline bitartrate, dihydrogen citrate choline, ironic citrate choline etc. multiple, is mainly used in industries such as medicine, foodstuff additive, fodder additives, makeup.
The choline method for making is to carry out condensation reaction with Trimethylamine 99, oxyethane in water or methyl alcohol, through chloroform extraction, evaporate to dryness, in ethanol recrystallization, drying under reduced pressure and get.Its salt is to be carried out salify and got by the aqueous solution of choline and corresponding acid.At present, China and external choline or its salt of producing all are not coated products, there are some defectives and deficiency to some extent, all very easily water-soluble, very easily absorb airborne moisture and dissolve, especially choline chloride 60 in use (production of vitamin complex) destroy other VITAMIN easily.
Summary of the invention
For solving the above-mentioned defective that choline and salt thereof exist, the invention provides a kind of dressing (overlay film) choline or its salt, and the dressing of choline or its salt (overlay film) technology.
Technical scheme of the present invention is: this kind dressing (overlay film) choline or its salt is characterized in that the salt of choline or choline is carried out choline or its salt that the overlay film dressing forms coating.
Above-mentioned dressing (overlay film) choline or its salt, its film-forming process is:
1), pour in the laminating machine after choline or its salt weighed, temperature of charge is controlled at 40 ℃-70 ℃;
2), open air compressor machine, pressure-controlling mixes up the spray gun position at 0.3-0.6mpa, open spray gun, utilize the high-pressure spray gun spraying that membrane-forming agent is sprayed on choline or its salt plane of crystal, the control temperature of charge is at 40 ℃-70 ℃, stop hydrojet during 40 ℃ of material temperature, stop heating during material temperature rise to 70 ℃; It is air-dry dry to continue heating, 30min shutdown, discharging, sieves, packs; Described membrane-forming agent is for to make uniform film liquid with the nontoxic film material of dissolution with solvents, and the weight ratio concentration that the film material accounts for mould liquid is 1%-10%; The coated back of product is controlled at 0.5-5% by the different requirement weightening finish of variant production.
In the aforementioned technology, described solvent can be selected dehydrated alcohol, 95% ethanol, acetone or ethyl acetate; The film material can be selected ethyl cellulose, Vltra tears, polyvinyl butyral or Xylo-Mucine.
Dressing film forming principle is in laminating machine, control certain temperature of charge and spraying pressure, utilize high-pressure spray gun spraying that membrane-forming agent is sprayed on choline or its salt plane of crystal, the solvent instant evaporation membranes material that is heated forms face attached to plane of crystal, promptly obtains a kind of dressing (overlay film) choline or its salt.
The invention has the beneficial effects as follows:
1), after choline or its salt coated (overlay film), epigranular, good fluidity fully is mixed with other material in the process easy to use.
2), after choline or its salt coated (overlay film), the film material makes product and air insulated, has reduced the water absorbability of product greatly, improved the stability of product, prolonged the validity period and the value preserving phase of product, be convenient to packing simultaneously, available general PVC material replaces expensive aluminum platinum material.
3), after choline or its salt coated (overlay film), in use avoided contacting, controlled destruction effectively, improved the stability of compound product greatly other products with the direct of other products.
