Embodiment 1

[0014] The raw material components are proportioned by weight: 39kg of fish meal, 20kg of soybean meal, 11kg of wheat, 2.8kg of fish oil, 10kg of cottonseed meal, 5.1kg of multidimensional multimineral premix, and 4.2kg of bread flour.

[0015] The production method is:

[0016] ①. The ingredients are pulverized and mixed. Weigh each raw material according to the weight ratio. First put the soybean meal, wheat and cottonseed meal into the pulverizer to crush them into 60-mesh raw material powder, and then add other raw materials into the mixing tank to stir and mix evenly to become a raw material mixed powder ;

[0017] ②. Extrusion and puffing to produce products, mix the above raw materials into full powder and put them into a fully cooked puffing extruder, and after conditioning for 300 seconds at a relative humidity of 22% and a temperature of 95°C, at the curing temperature of 110°C and the pressure of the puffing machine cavity Under the condition of 3.5MPa, aging for 1...

Embodiment 2

[0019] The proportion of each raw material is as follows: fish meal: 42kg, soybean meal 19kg, wheat 10kg, fish oil 2.6kg, cottonseed meal 11kg, multidimensional multimineral premix 4.8kg, bread flour 5.3kg, shrimp meal 16kg, squid meal 15kg, 9.5kg of puffed soybeans.

[0020] The production method is:

[0021] ①. The ingredients are pulverized and mixed. Weigh each raw material according to the weight ratio. First put the soybean meal, wheat, cottonseed meal, and puffed soybean into the pulverizer to crush them into 70-mesh raw material powder, and then add other raw materials into the mixing tank and mix them evenly to form a raw material mixture. whole powder;

[0022] ②. Extrusion and puffing to produce products, mix the above raw materials into full powder and put them into a full-cooked puffing extruder. Under the condition of 3.4MPa, aging for 130 seconds, the slow-settling semi-suspension granular fish feed product II was obtained, and the measurement results showed t...

Embodiment 3

[0024] The proportion of each raw material is as follows: fish meal 46kg, soybean meal 23kg, wheat 13kg, fish oil 3.5kg, cottonseed meal 12kg, multidimensional multimineral premix 5.4kg, bread flour 5.3kg, shrimp meal 13kg, hemoglobulin powder 15kg .

[0025] The production method is:

[0026] ①. The ingredients are pulverized and mixed, and the raw materials are weighed according to the weight ratio. First, the soybean meal, wheat, and cottonseed meal are crushed into a 80-mesh raw material powder, and then other raw materials are added into the mixing tank and mixed evenly to become a raw material mixed powder;

[0027] ②. Extrusion and puffing to produce products, mix the above raw materials and put them into a full-cooked puffing extruder. Under the condition of 3.4MPa, aging for 150 seconds, the slow-settling semi-suspension granular fish feed product III was obtained, and the measurement results showed that the density was 0.93 and the stability in seawater was 13.5 hou...

Abstract

The invention provides slow sinking suspension type fish feed and a preparation method thereof and belongs to the technical field of feeds, and the slow sinking suspension type fish feed is used for solving the problems of high feed coefficient, low feed utilization rate and water quality pollution of the current fish feed. The slow sinking suspension type fish feed is composed of the following ingredients in weight ratio: 370.-48.0 parts of fish meal, 17.0-25.0 parts of bean pulp, 8-14 parts of wheat, 2.3-3.7 parts of fish oil, 8.6-12.5 parts of rapeseed dregs, 4.3-5.8 parts of multi-dimensional mineral premix and 3.8-5.6 parts of bread flour. The fish feed is prepared by weighing, crushing, mixing, expanding and extruding the raw materials, the feed coefficient of the slow sinking suspension type fish feed is 0.9-1.0, and the water stability of the shrimp feed is larger than 12 hours. The fish feed is suspended underwater for about 30-200cm underwater or deeper, namely, being located at a semi-suspension state after being scattered in the water, and the preparation method is simple, so that the slow sinking suspension type fish feed is suitable for breeding freshwater fish and marine fish.

Description

technical field [0001] The invention belongs to the technical field of feed, a feed for feeding fish in the aquaculture industry and a preparation method thereof. Background technique [0002] With the increasing development of the aquaculture industry and the rapid advancement of science and technology, the technical requirements for feeding fish feed in the aquaculture industry are also getting higher and higher. In the known technology, the existing fish feed is mainly divided into two categories, one is hard particles combined with sinking feed, the feed coefficient is above 1.1, sinks into the breeding pond, the feed utilization rate is low, and pollutes the water quality; the other The first type is floating fish feed, which mainly includes fish meal, wheat, flour, fish oil, yeast powder, mineral premix, vitamin premix and soybean meal, cottonseed meal, peanut meal, rapeseed meal and other meals. Pellet feed made by extrusion extruder, but limited by its components an...
