Problems solved by technology

[0004] However, the raising of shrimps is generally carried out in the breeding ponds, and the shrimps generally prey along the walls of the breeding ponds, and the density of the shrimp feed is reduced after the puffing treatment, and it is easy to float in the water, and the puffed shrimp feed is easy to float to the The various positions of the feeding pond are not convenient for shrimps to concentrate on predation along the wall of the feeding pond, which reduces the utilization rate of shrimp feed to a certain extent

Embodiment 1

[0037] Embodiment 1: a kind of shrimp feed preparation technology, comprises the steps:

[0038] S1 Mixing: Weigh 12kg soybean flour, add 10kg corn flour, 10kg wheat flour, 7kg soybean meal, 6kg peanut meal, 2kg squid paste, 1.8kg citric acid, 1.5kg acetate starch, 2.5kg konjac flour, 1.5kg soybean dietary fiber and 1.2kg of calcium hydrogen phosphate, mixed evenly, pulverized with a pulverizer, sieved with a sieve with a pore size of 120 μm, and the particles with a particle size greater than 120 μm were continuously pulverized until the particle size was not greater than 120 μm to obtain a mixture.

[0039] S2 puffing: transfer the mixed material to the conditioner at 150°C, pass water steam into the conditioner for 5 minutes, adjust the amount of water vapor introduced so that the water content of the mixed material is 32%, and prepare the tempered material; The conditioning material is extruded and cut with a twin-screw extruder to obtain extruded granules;

[0040] S3 De...

Embodiment 2

[0043] The difference between embodiment 2 and embodiment 1 is that embodiment 2 does not add soybean dietary fiber, and others are consistent with embodiment 1.

Embodiment 3

[0045]The difference between embodiment 3 and embodiment 1 is that embodiment 3 does not add calcium hydrogen phosphate, and others are all consistent with embodiment 1.

Abstract

The invention discloses a preparation process of a shrimp feed and the shrimp feed prepared by the preparation process and relates to the technical field of shrimp feeds. The preparation process of the shrimp feed comprises the following steps of: S1, material mixing: weighing raw materials of a shrimp feed, mixing the raw materials evenly and crushing the raw materials to prepare a mixture; S2, extrusion: introducing water vapor into the mixture for performing tempering for 3-8 minutes under the condition that the tempering temperature is 145-160 DEG C to prepare a tempered material, and extruding and cutting the tempered material by using an extruder to prepare extruded granules; S3, density control: transferring the extruded granules into a density controller, reducing the volume of theextruded granules by air pressurization, pressing the extruded granules until the density is not smaller than 1.02 g / ml to prepare a heavy material; and S4, drying: drying the heavy material at 120-140 DEG C for 35-50 minutes to prepare a shrimp feed. The preparation process of the shrimp feed has the advantage that the utilization rate of the shrimp feed is improved; and the shrimp feed preparedby the preparation process of the shrimp feed has the advantage that predation of shrimp animals is facilitated.

Description

technical field [0001] The invention relates to the technical field of shrimp feed, in particular to a preparation process of shrimp feed and the prepared shrimp feed. Background technique [0002] Freshwater prawns, river prawns, grass prawns, prawns, prawns, crayfish and other shrimps are rich in nutrients such as protein and calcium, and have high therapeutic nutritional effects. With the improvement of people's living standards, crayfish and other shrimp The aquaculture industry of aquatic products has developed rapidly. In order to improve the feeding efficiency of shrimp animals, it is generally necessary to use shrimp feed when raising shrimp animals. Feed material expansion treatment can reduce bacteria and improve feed safety, and feed material expansion treatment also facilitates the absorption and digestion of shrimp feed by shrimp animals. Therefore, the existing shrimp feed preparation process is generally to make shrimp feed raw materials into puffed feed. ...
