Abstract
DL-cysteine products produced by a novel DL-cysteine production device are widely used in the pharmaceutical field, the food field and the daily chemical product field. In the prior art, most DL-cysteine products are produced by adopting cystine or L-cysteine crystals as the raw material, but the process is complex. Aiming to correct the deficiency, the utility model provides a production device using DL-cysteine hydrochloride as the raw material to produce DL-cysteine; and the device has the advantages of simple structure, little working procedure and high efficiency, and can produce DL-cysteine products of high quality. The novel DL-cysteine production device comprises a chemical reaction kettle, a filter, a concentration and crystallization tank, and a baking oven.
Description
Affiliated technical field:
The utility model relates to a kind of DL-cysteine production equipment, specifically is a kind of production equipment that uses the DL-cysteine hydrochloride to come the production DL-cysteine as raw material.
Background technology:
DL-cysteine is the human body non-essential amino acid.It with the difference of L-halfcystine is: in the amino acid with carbon atom that carboxyl directly links to each other on have amino, group on this carbon atom or atom are all different, claim chiral carbon atom, when a branch of polarized light passes through them, the polarisation of light direction will be rotated, being divided into left-handed and dextrorotation according to the direction of rotation is D system and L system, and the L-halfcystine has only L system, and the then existing L of DL-cysteine system has D to be.Just because of the existing L of DL-cysteine system D system is arranged again, and make its performance of all respects both close with the L-halfcystine, be better than the L-halfcystine again slightly, it is the upgrading products of L-halfcystine.DL-cysteine has purposes widely, and aspect medical: DL-cysteine mainly as the intermediate of medicine and the production of bulk drug, can be used for the liver medicine, toxicide, pharmaceuticals such as expectorant; For liver poisoning detoxifcation, antipyretic-antalgic, eliminate the phlegm, treat bronchitis, reduce phlegm, ulcer treatment, fatigue recovery etc. have curative effect preferably.Aspect food: can be used as foodstuff additive, bread fermentation promotor, preservation agent, also can be used for fodder additives.Aspect household chemicals, be the important materials of dyestuff, pigment and intermediate, can be used for producing hair-waving essence, sunscreen, perfume, hair care essence etc.DL-cysteine is colourless crystallization shape material, and is little smelly, flavor acid, and soluble in water, acetate, ammoniacal liquor and ethanol are insoluble to ether, benzene, acetone, ethyl acetate, dithiocarbonic anhydride and tetracol phenixin; In neutrality or micro alkaline solution, easily be oxidized to Gelucystine, but trace iron and heavy metal ion promotes oxidn, can stable existence in acid.Production DL-cysteine now is many to be that raw material comes production DL-cysteine product with Gelucystine or L-halfcystine xln, but technology shows complexity slightly.
Summary of the invention:
In order to overcome above-mentioned defective, it is the production equipment that raw material comes the production DL-cysteine with the DL-cysteine hydrochloride that the utility model provides a kind of, and this apparatus structure is simple, and operation is few, and the efficient height can be produced high-quality DL-cysteine product.
The technical scheme that the utility model adopts for the problem that solves original technology existence is:
A kind of novel DL-cysteine production equipment comprises chemical reaction kettle, strainer, condensing crystal jar, baking oven.Chemical reaction kettle is to being provided with first Ordinary Centrifugal Pumps and pipeline between strainer; Strainer is provided with second Ordinary Centrifugal Pumps and pipeline between the condensing crystal jar; The condensing crystal jar is provided with transfer roller between baking oven.
Further technical scheme of the present utility model is:
Described chemical reaction kettle inner bag is the acid proof enamel material.
Described whole pipeline is a pvc pipe.
The beneficial effects of the utility model are: the production equipment of this novel DL-cysteine provides a kind of industrial production device efficiently rationally, and this apparatus structure is reasonable, and technology is simple, the efficient height, and cost is low, can produce high-quality DL-cysteine finished product.
Description of drawings:
As figure is the utility model principle schematic.
Embodiment
Embodiment: a kind of novel DL-cysteine production equipment comprises chemical reaction kettle 1, strainer 2, condensing crystal jar 3, baking oven 4.Chemical reaction kettle is to being provided with first Ordinary Centrifugal Pumps and pipeline 5 between strainer; Strainer is to being provided with second Ordinary Centrifugal Pumps and pipeline 6 between the condensing crystal jar; The condensing crystal jar is to being provided with transfer roller 7 between baking oven.
Described chemical reaction kettle inner bag is the acid proof enamel material.
Described whole pipeline is a pvc pipe.
Use the method for this novel DL-cysteine production equipment production DL-cysteine as follows:
One, will add quantitative water in the chemical reaction kettle, be warming up to 45 degree Celsius then, start stirrer, add quantitative DL-cysteine crystal of hydrochloride body, stir, add quantitative alkali then and carry out neutralization reaction.
Two, reacted liquid is sent into strainer 2 by 5 and filter elimination impurity.
Three, the liquid after will filtering is sent into condensing crystal jar 3 by 6, carries out condensing crystal.
Four, the semisolid behind the condensing crystal is sent into baking oven by 7.Obtain the DL-cysteine xln after the drying.
