Embodiment Construction

[0019] The invention discloses a soft granular feed and a preparation method thereof, comprising the following steps: S1 raw material, S2 freezing, S3 cutting into pieces, S4 preparation of embedding agent, S5 adding attractant, S6 embedding, and S7 packaging.

[0020] The raw materials of step S1 are chilled surimi and chilled fish.

[0021] Step S2 Freezing: The frozen product tray containing fresh surimi and fresh fish to be frozen enters the quick-freezing chamber through the quick-freezing inlet and moves step by step toward the outlet. Heat exchange is realized during the moving process to achieve rapid cooling and freezing.

[0022] Step S3 dicing: dicing the frozen surimi and chilled fish into granules.

[0023] Step S4 preparation of embedding agent: heating the embedding agent with distilled water to make liquid.

[0024] Step S5 Adding the attractant: Add the attractant to the liquid embedding agent and stir evenly.

[0025] Step S6 Embedding: Embedding the partic...

Abstract

The invention discloses a soft granulated feed and a preparation method thereof. The soft granulated feed comprises the following steps: S1. preparing raw materials; S2. freezing; S3. dicing; S4. preparing an embedding agent; S5. adding a feed inducing agent; S6. embedding; and S7. packaging. The soft granulated feed provided by the invention is convenient in production process, sufficient in raw materials, low in cost, long in time of retention in water, low in dissolved rate, high in demand and favorable for large-scale production; the feeding of aquatic animals is not influenced after the food inducing agent is added.

Description

technical field [0001] The invention relates to a granular feed for aquatic products and a preparation method thereof, in particular to a soft granular feed and a preparation method thereof. Background technique [0002] In river crab culture, as growth conditions, living space and nutrition are two basic elements. As a production process, it is the goal of aquaculture to obtain continuous production of aquatic products through material circulation. Organic pollutants are the biggest obstacle to the normal circulation of substances in the crab culture ecosystem, and artificial compound bait is the largest source of organic pollutants in aquaculture. The quality of artificial compound bait has an important impact on aquaculture production and aquaculture environment. Traditional artificial bait development is aimed at the pursuit of maximum weight gain or growth rate. The bait contains a lot of phosphorus and is often overfed. Such bait and feeding methods often cause water q...
