Problems solved by technology

[0002] With the rapid development of the aquaculture industry, traditional breeding methods are far from meeting people's needs. The requirements for aquatic feed are not only balanced nutrition, good stability of feed in water, etc., but also the environment in which animals live.

Embodiment Construction

[0010] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0011] An extrusion and extruding process for aquatic feed, comprising the steps of:

[0012] (1) Raw materials for puffing are crushed by a hammer mill with a sieve aperture of 1.5-2.0 mm, and the particle size of the raw materials is controlled at 0.5-1.4 mm.

[0013] (2) Send the pulverized and mixed materials to the conditioner to give a certain amount of moisture and temperature. The temperature and humidity of the material are often injected with steam or hot water. The temperature of the material is controlled at 60-90°C, and the moisture on a wet basis is 20-30%.

[0014] (3) In the tempering process, liquids such as flavoring agents, pigments, oils, and meat pulp can also be added. The amount of grease added is 1 to 5%, and the rest should be sprayed on the particles in the post-processing.

[0015] (4) The mixed material after quenchi...

Abstract

The invention discloses an extrude-puffing processing technology of aquatic feed. The extrude-puffing processing technology of aquatic feed especially comprises the following steps: crushing the raw materials by a paddle mill and fully mixing the crushed materials in a mixer; sending the crushed and mixed materials into a conditioner and providing appropriate moisture and temperature to the crushed and mixed materials, so that the temperature is controlled at 60-90 DEG C and the wet-base moisture is controlled at 20-30%, and seasoning agents, pigments, fat as well as liquids such as meat pulp and the like can also be added during the conditioning process; sending the conditioned mixture into a puffing chamber, so that the mixture is pushed by a high-speed rotating screw rod into different areas; suddenly reducing the pressure when the mixture enters into the atmosphere through the circular mould hole, so that the mixture expands impetuously due to rapid escape of the steam; and then, treating the expanded mixture in a drying, cooling and spray-coating post-treatment system after the expanded mixture is shaped by expansion-molding by a molding template.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to an extrusion and puffing process of aquatic feed. Background technique [0002] With the rapid development of the aquaculture industry, traditional farming methods are far from meeting people's needs. The requirements for aquatic feed are not only balanced nutrition, good stability of feed in water, etc., but also the environment in which animals live. The quality of the water body puts forward stricter requirements. The production process of aquatic extruded feed is very different from that of traditional livestock and poultry feed. [0003] According to the characteristics of many varieties of aquatic feed, large changes in raw materials, high requirements for crushing fineness, and poor fluidity of materials, the production process generally adopts secondary crushing and secondary ingredient mixing, and then undergoes puffing, drying, external spraying, coo...
