Description

A kind of preparation method with powdered oil feed of whey powder
Technical field
The present invention relates to a kind of feed, especially relate to a kind of preparation method with powdered oil feed of whey powder.
Background technology
Albumen, whey powder, grease are the nutrient raw material of commonly using, but at present in complete feed, they are simple mix and blends, shortcoming is that animal is low to its grease, proteopepsis utilization rate, unhygienic (because albumen, whey powder, grease all portable bacterial virus), period of storage short (because easily oxidation of fat, whey powder easily lumps) etc.
In fat powder for feed (or feed oil-bound distemper), newer technology is to do carrier with albumen at present, and grease and albumen is through Over emulsfication, homogeneous, more spray-dried, becomes pressed powder.Its shortcoming is coated not exclusively to cause that material viscous easily lumps, and is not smooth; The hypotrophy face is especially for brood (as the wean sucking pig).
Summary of the invention
The present invention is to provide a kind of preparation method with powdered oil feed of whey powder, it is mainly that in the existing feed of solution prior art, albumen, whey powder, grease are simple mix and blends, animal is low to its grease, proteopepsis utilization rate, albumen, whey powder, grease be portable bacterial virus all, cause unhygienic, the technical problem of the short grade of period of storage.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of preparation method with powdered oil feed of whey powder of the present invention is characterized in that described method comprises:
A. be 1-40% whey powder, 0-60% vegetable protein, 0-60% animal protein with mass percent, 0-60% animal fat, 0-60% vegetable fat mix in proportion; In the present invention, the indication vegetable protein refers to the albumen that itself contains in all plant products and the albumen that extracts.Animal protein refers to the albumen that itself contains in all animal products and the albumen that extracts.Vegetable fat refers to the grease that itself contains in all plant products and the grease that extracts.Animal fat refers to the grease that itself contains in all animal products and the grease that extracts.
B. the raw material of working good is added to the water, adding mass percent after heating is 0.1-4% emulsifying agent, fully stir, then entering mulser processes, the pressure of mulser charging aperture and discharging opening is 0.1-0.3MPa, by the stator of three groups of High Rotation Speeds, the material particular diameter shearing is about the 0.2-2 micron; Except this model mulser, also comprise the emulsification machinery that other has emulsification function.
C. the product after emulsification is processed by the homogenizer homogeneous, this moment, temperature of charge was less than 90 ℃, the charging of homogenizer self-suction, by low pressure handle and high pressure handle, homogenizer pressure is transferred to 3.4-35MPa, under high pressure produce powerful shearing, shock and cavitation, make material homogeneous and further ultra micro refinement, with the particle diameter homogeneous shear below 0.2 micron;
D. the product after homogeneous carries out spray-drying by the spray-dried tower of frequency conversion dry technology, 195-400 ℃ of tower intake air temperature. 92-120 ℃ of air outlet temperature, material is to become droplet in 13000-18000 rev/min of high speed centrifugal atomization device by rotating speed, perhaps become droplet by high-pressure atomizer, the contact area of feed liquid and hot-air is increased greatly, moisture content evaporates rapidly, becomes powder; Safety and sanitation of the present invention, secret worry is few.The portable bacterial virus of whey powder in the present invention.But by after the spray-drying more than 195 ℃, the whole deactivations of these bacterial viruses.The present invention clips to material particular diameter below 0.2 micron by emulsification shearing, homogeneous twice technique, makes the infull brood of gastrointestinal development carry out accessible absorption to its nutrition.Especially the particle diameter of whey powder, fat, albumen is equally little, so its absorption is more comprehensive, nutrition is more balanced.
E. dried mixture, namely go out a kind of powdered oil feed with whey powder of finished product after sieving, measuring, pack.
primary raw material of the present invention: whey powder, vegetable protein (pea protein, wheat gluten, large aleuronat, the avenin FSPC, soybean protein isolate, textured soybean protein, dregs of beans, peanut protein etc.), animal fat (lard, chicken fat, duck oil, butter, cream etc.), animal protein (fish meal, plasma protein, hyperglobulinemia etc.), vegetable fat (soybean oil, coconut oil, olive oil, rice bran oil, sesame oil, sunflower oil, safflower oil, palm oil, rape oil, peanut oil, cotton oil etc.), emulsifying agent (acetic acid and fatty glyceride, cholic acid, lecithin, other food and feeds emulsifying agent such as polysorbate).
The present invention can improve the integrality of fatty powder coating, improves the fluency of material, prevents caking.
Because whey powder itself has the coating function, add that itself contains casein, casein has emulsification function, so after adding whey powder, can improve the fluency of fatty powder, prevents caking.
The present invention can reduce the emulsifying agent addition, and whey powder itself has the coating function, adds that itself contains the casein of emulsification function, so the whey powder addition is in the words more than 10%, the addition of emulsifying agent can be reduced, because emulsifying agent is expensive, so just cost can be saved.
The easy moisture absorption caking of whey powder goes common emulsification if it is added in fatty powder, coated with albumen, due to the resistance to water soak of fat and albumen.Can prevent like this moisture absorption caking of whey powder, extend the holding time.
Whey powder can cause the reduction of palatability and utilization rate in hot and humid lower storage; With whey powder emulsification, coated with albumen, this problem just can solve the problem of whey powder quality variation in storage process in processing method.
In sum, adding whey powder in fatty powder, both can improve the performance of fatty powder, can improve again the performance of whey powder, is a good method of achieving many things at one stroke.
Add whey powder in fatty powder, making it becomes the product that the most suitable cub is used, and in cub, because digestive system development is incomplete, except lactose, other carbohydrate can not digest.Lactose in whey powder is its best energy source.So this product has whey powder, albumen, three kinds of nutrient sources that animal needs most of fat, all through after emulsification treatment, become a kind of health, comprehensive nutrition, extremely digestible food sources, not only itself has high-absorbility, can also form the good ecology of digesting and assimilating with other albumen, carbohydrate, vitamin, trace element in enteron aisle, to improve gastrointestinal tract environment.Repair the damage of sucking pig wean rear intestinal.Increase intestinal absorption area, protection microvillose membrane, in each microbial toxin, suppress sex pheromone.Can reduce diarrhoea, when palindromia, provide the cub immunologic function in good time, shorten smelting and treat process, promote the cub growth.
The present invention with whey powder and fatty powder mixing and emulsifying drying after, its result of use is far superior to fatty powder and whey powder adds separately.We have done a test on the pig farm, Zhejiang to sucking pig.Every group 50, test group is for adding this product, and control group is that fatty powder is with whey powder, its product composition is the same with addition, and result shows: the test group daily gain improves 12% left and right than control group, and 6.5% left and right falls in feedstuff-meat ratio, 18% left and right falls in the diarrhoea number of times, and feed intake increases by 8%.
As preferably, the temperature that heats up in described step b is controlled at 50-100 ℃, and the rotating speed of stator is 2900 rev/mins.
As preferably, in described step c, the frequency conversion drying is the moment frequency conversion.
As preferably, described mulser includes the mulser frame, and the mulser frame is provided with motor, motor is connected with rotating shaft, rotating shaft is passed in housing and is connected with three groups of stators, and the outer end of housing is provided with the mulser material inlet, and the top of housing is provided with the mulser material outlet.
