Abstract

The invention relates to the field of pelteobagrusfulvidraco feed production, especially discloses a production method for pelteobagrusfulvidraco puffed mixed feed, and the production method is high in protein content and low in production cost. The production method comprises: first step, burdening, storing raw materials with large ratios in corresponding batch bins by an elevator; second step, pouring the raw materials into a mixer after the raw materials are auto-weighed by a batching scale, stirring for 5-10 min; third step, storing the uniformly mixed raw materials in a to-be smashed bin for superfine smashing; forth step, adding small-ratio raw materials and performing secondary mixing; fifth step, granulating and puffing; sixth step, spraying grease externally; seventh step, performing countercurrent cooling by a high-pressure blower and sending into a finished product bin, sieving to remove non-standard particles and powder; and eighth step, checking out, weighing, packaging, marking and warehousing. According to the production method for the pelteobagrusfulvidraco puffed mixed feed, the prepared pelteobagrusfulvidraco puffed mixed feed has a feed coefficient of 1.3-1.5, has a crude protein content of 45-52%, is improved in nutritional components and helps to promote growth of pelteobagrusfulvidraco.

Description

The production method of Pseudobagrus fulvidraco puffed formulated feedstuff

Technical field

The present invention relates to yellow-head catfish feed production field, especially a kind of production method of Pseudobagrus fulvidraco puffed formulated feedstuff.

Background technology

The whole world increases year by year to the consumption of aquatic products, and diet structure changes.And that global ocean is fished for is limited, it is main that aquaculture product is given in the confession of aquatic products.China is the maximum aquaculture big country in the whole world, and aquatic products total output accounts for 35% of the whole world, and wherein aquaculture product output accounts for 70% of the whole world.In Aquatic products consumption demand rapid growth, the aquaculture water resource of China is on a declining curve.And to meet the growth of aquatic products demand, inevitable take propagate artificially as main, thereby more effectively existing aquaculture water resource is used.Propagate artificially and depend on feed, strengthened the demand to the quality and quantity of aquatic feeds.

Summary of the invention

The object of the invention is to provide in order to solve the deficiency of above-mentioned technology the production method of the Pseudobagrus fulvidraco puffed formulated feedstuff that a kind of protein content is high, production cost is low.

In order to achieve the above object, the production method of the Pseudobagrus fulvidraco puffed formulated feedstuff that the present invention is designed, formula rate is: 60 albumen fish meal 8%, 62 albumen fish meal 20%, 66 albumen fish meal 5%, dehulled soybean meal 35%, corn protein powder 5%, Strong flour 20%, liquid phosphatidase 11 %, the mixture 3% of soya-bean oil and fish oil, calcium dihydrogen phosphate 1.5%, salt 0.2%, Choline Chloride 0.3%, 925 premix 2%; Wherein the ratio of soya-bean oil and fish oil is 3:1; The first step: batching, by vast scale raw material: 60 albumen fish meal, 62 albumen fish meal, 66 albumen fish meal, dehulled soybean meal, corn protein powder and Strong flour are stored in corresponding batch bin by sample through elevator, middle control arranges each raw material quantitative proportion, second step: raw material drops into mixer after burden balance automatic gauge, stir 5-10 minute, assurance fineness 90% is crossed 80 mesh sieves; The 3rd step: the raw material mixing leaves in treats crushing bin, carries out ultramicro grinding, assurance fineness 98% is crossed 80 mesh sieves; The 4th step: the material after ultramicro grinding enters two mixed machines through elevator, high pressure positive blower, pulse dust collector, carries out secondary mixing after liquid phosphatide, calcium dihydrogen phosphate, salt, Choline Chloride and 925 premixes are added, and mixes; The 5th step: granulate expanded, use 1.2 aperture ring moulds of corresponding requirements, adjust granulation speed, inside add water vapour, cavity temperature reaches 120 degrees Celsius, slaking and sterilization; The 6th step: outer oil spout fat, grease is the mixture of soya-bean oil and fish oil, grease heats more than 85 degrees Celsius, through flowmeter, by formula ratio, sets outer spray, makes feed granules outward appearance reach color and luster even, the smooth full requirement of particle; The 7th step: enter finished bin after high pressure positive blower adverse current is cooling, sieve and screen out nonstandard particle and powder; The 8th step: be up to the standards, the packing of weighing, mark warehouse-in.

The production method of the resulting Pseudobagrus fulvidraco puffed formulated feedstuff of the present invention, its feed coefficient of whitefish expanding compound feed making by the method can reach 1.3-1.5, and the crude protein content in feed can reach 45-52%, improved the nutrition of feed, promote the growth of fish.
