Embodiment
[0049] see figure 1 , a preparation process of net bag type fish feed, comprising the following steps:
[0050] S1. Weigh fish feed raw materials: rice bran 35%-45%, bran 32%-42%, bean cake 5%-10%, fish meal 5%-15%, yeast powder 1%-3%, vitamin 0.5-1.5% ;
[0051] S2. Grinding and fully mixing the above-mentioned fish feed raw materials, sending the pulverized raw materials into a granulator to granulate to obtain granular fish feed;
[0052] S3. Add the screened irregular gravel-like closed-cell ceramic particles to the pelleted fish feed in a certain proportion, and mix them uniformly to obtain pelleted feed;
[0053] S4. After drying the grain-mixed feed, it is injected into a plurality of bag-mouth net bags respectively, that is, divided into net packaging, and the bag-mouth net bags are sealed to form the final net bag feed.
[0054] The diameter of the net bag feed in step S1 is 2cm-6cm.
[0055] In step S3, the particle size of the closed-cell ceramic particles is 1 ...

Abstract
The invention discloses a preparation process of a net-wrapped fish feed, and belongs to the field of fish feeds. Irregular gravel-shaped closed-cell ceramic particles are doped into a granular fish feed, so that on one hand, the gap between the granular fish feeds can be increased, the filling power of the feed can be improved, and the internal moisture of the feed can be conveniently dissipated; on the other hand, the granular fish feed doped with the closed-cell ceramic particles is injected into a net bag with an opening to form the net-wrapped feed; when the net-wrapped fish feed is put into use, the rate of the granular fish feed sinking into the water bottom can be reduced through the common buoyancy of the closed-cell ceramic particles and the net bag with the opening, the flowing time of the granular fish feed is prolonged, and the large-area diffusion degree of the granular fish feed in water is improved; and moreover, after most of the granular fish feed is diffused, the net bag with the opening can drive the closed-cell ceramic particles and the residual fish feed to float upwards, thus, the circumstance that the fish feed sinks to the bottom is effectively reduced, and meanwhile, on the basis that impurity pollution is not caused to a water body, the closed-cell ceramic particles and the net bag with the opening are collected and recycled.
Description
technical field [0001] The invention relates to the field of fish feed, and more specifically, relates to a preparation process of net bag type fish feed. Background technique [0002] Fish feed, as the name suggests, is feed for fish. Its main components are protein, fat, vitamins and minerals. Protein is an important nutrient for the survival of fish and shrimp, and an important component of the cells, tissues and organs of the body. [0003] The diameter of fish pellet feed is usually 2.5-8.0mm, and the length is 5-10mm, which can be directly sprinkled and fed. If the feed is damp, do not feed it directly. It should be dried or dried before feeding. [0004] When feeding a large amount of fish feed in fish ponds, it is easy to cause a large amount of fish feed to sink to the bottom, and it is easy to make insufficient use of the feed, accumulate in large quantities for a long time, and easily pollute the water quality. Contents of the invention [0005] 1. Technical...
