Compared with the prior art, the rumen bypass methionine product is low in production cost, simple un process and easy to produce continuously, and is free of organic reagent, non-pollution to the environment, regular in shape, and narrow in particle size distribution, adding and premixing are easy, and the product qualification rate is high.
Description
Technical field
The present invention relates to a kind of amino acid whose preparation technology, especially relate to a kind of technique preparing rumen bypass methionine.
Background technology
Rumen bypass methionine production technology common at present has chemic modified method and bag by method.Wrapping by method general step is first in methionine, add some auxiliary materials (as glucose, lecithin, kaolin) and carry out granulation process, and re-using some, to carry out bag at the lower wall material (as lipid, high molecular polymer) of Rumen Degradation to methionine processed; Generally for and reach good rumen bypass effect and need to carry out multiple coatings to product, production technology relative complex and discontinuous, consuming time longer, energy consumption is higher, meanwhile, needs cost higher.
The general principle of spray cooling is that core material is suspended, is scattered in the wall material of melting state, then is sprayed to by heated nozzle and keep spraying in the hothouse of low temperature, makes wall material solidify to form the technology of microcapsules.During this technology uses usually, the lipid of low melting point or wax are wall material, and product is the globule of larger particles, have technique simple (product can one-shot forming), advantage that economical and energy saving, product percent of pass are high.The low melting point such as palm oil, stearic acid grease does not decompose in ruminant tumor gastric, and decomposes in small intestine, therefore with low melting point grease for wall material, use spray cooling microencapsulation process is carried out to methionine, the preparation of rumen bypass methionine can be realized.
Application number be 200910093813.9 Chinese patent disclose rumen protected methionine and production method thereof, the rumen protected methionine of preparation is made up of core and shell two parts, and shell is rumen-undegraded fat powder, and the active component of core is methionine.In contrast, 1. this patent technology used is spray cooling, is not packaging technique, and product is embedding type microcapsules; 2. this patent wall material used is HPO, and cost of material is cheaply easy to get, and above-mentioned patent wall used material is special rumen-undegraded fat powder, needs to buy through particular vendors; 3. the art of this patent simplifies technique, and product can one-shot forming.Above-mentioned patent needs to carry out granulation process to methionine in advance, then carries out Cotton seeds, in this patent, does not need granulation treatment product to get final product one-shot forming.4. the art of this patent can accomplish continuous prodution, and above-mentioned patented technology then can not.5. bag is by effect in order to reach preferably for art for coating, and need long time, energy consumption is corresponding also can be very high, and this technique preparing product spended time is shorter, and energy consumption is low.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and provide a kind of simple to operate be easy to simultaneously produce serialization, the technique preparing rumen bypass methionine of environmentally safe.
Object of the present invention can be achieved through the following technical solutions:
Prepare a technique for rumen bypass methionine, methionine is scattered in the grease of 80-90 DEG C, homogeneous 2-3h, then controlled cooling model room temperature is 8-10 DEG C, sprays, and namely obtains rumen bypass methionine after sieving.
The technique preparing rumen bypass methionine specifically adopts following steps:
(1) melt wall material and drop into core
Heat to melting pot, temperature controls at 80-90 DEG C, and then drop into the grease accounting for system gross mass 40-60%, turn on agitator, is stirred to grease and all melts, under agitation slowly add methionine;
(2) homogeneous
Feed intake after terminating, arranging homogenizer rotating speed is 1300r/min-1500r/min, processes the material obtained carry out stirring homogeneous 2-3h to step (1);
(3) spray
Before spraying, 5min opens refrigeration machine, and arranging cooling chamber temperature is 8-10 DEG C, and controlling atomizer rotating speed is 30-40Hz, carries out spraying process to homogenous mass;
(4) sieve, measure, pack
Utilize vibratory sieve to collect interlayer product and carry out metering packing, namely obtain rumen bypass methionine.
As preferred embodiment, grease adopts low melting point grease.
As the embodiment be more preferably, low melting point grease is stearic acid, hydrogenated oil and fat or palm oil.
In homogenizing process, adopt steam to carry out preheating to material conveying pipe.
In spray process, homogenizer and mixer continue maintenance work.
Described vibratory sieve is 18 order-60 object vibratory sieves.
Compared with prior art, the present invention has the following advantages:
(1) rumen bypass methionine utilizing production technology of the present invention to prepare, production cost is lower, the serialization being simultaneously easy to produce simple to operate, and does not use organic reagent, environmentally safe;
(2) the rumen bypass methionine shape of product rule, the narrower particle size distribution that utilize production technology of the present invention to prepare, be easy to add and premix, and product percent of pass is higher.
(3) technology of the present invention is utilized, product can one-shot forming, energy consumption is low, technique is simple, overcome that the wall material cost that bag existed for rumen bypass methionine at present by legal system is high, complex process, production technology is discontinuous, longer, problem that energy consumption is higher consuming time, thus reaches the object efficiently preparing rumen bypass methionine.
