Preparation method and preparation device of eel compound feed

Abstract

The invention discloses a preparation method and a preparation device of an eel compound feed, and relates to the technical field of feed preparation. The preparation method of the eel compound feed comprises the following raw materials in parts by weight: 60-70 parts of white fish meal, 10-15 parts of shrimp meal, 10-15 parts of corn flour, 8-10 parts of wheat gluten flour, 10-12 parts of fermented soybean meal, 3-5 parts of saccharomyces cerevisiae, 1-3 parts of an eel vitamin additive, 1-3 parts of an eel mineral additive, 3-5 parts of a traditional Chinese medicine herb extracting solution and purified water. The preparation method comprises the following steps of preparing the raw materials, performing drying and performing granulation. According to the preparation method of the eel compound feed, the produced eel compound feed can effectively prevent the problem of eel enteritis, promote absorption and conversion of the feed by eels, meet requirements of the eels for various nutrient components, promote the conversion rate of the feed, effectively increase the food intake of the eels, and further increase the growth speed of the eels.

Description

technical field [0001] The invention relates to the technical field of feed production, in particular to a preparation method and a preparation device of eel compound feed. Background technique [0002] Eel is a kind of fish belonging to the eel family Eelidae. Most of the eels on the market are cultured eels. In the process of eel cultivation, the feed determines the taste of the eels. For example, the patent publication number is CN104522373A, in which the feed energy produced is high. , can ensure the growth needs of eels, but there is a problem that eels are likely to cause enteritis in the process of eating, which leads to low feed absorption and conversion rate. Therefore, it cannot be accepted by the majority of farmers, and it is not easy to promote. In the process, the raw materials need to be mixed and pulverized. Some preparation devices have incomplete pulverization when they are screened after pulverization. The screens are often blocked due to incomplete pulver...

[0002] Eel is a kind of fish belonging to the eel family Eelidae. Most of the eels on the market are cultured eels. In the process of eel cultivation, the feed determines the taste of the eels. For example, the patent publication number is CN104522373A, in which the feed energy produced is high. , can ensure the growth needs of eels, but there is a problem that eels are likely to cause enteritis in the process of eating, which leads to low feed absorption and conversion rate. Therefore, it cannot be accepted by the majority of farmers, and it is not easy to promote. In the process, the raw materials need to be mixed and pulverized. Some preparation devices have incomplete pulverization when they are screened after pulverization, and the screens are often blocked due to incomplete pulverization, which affects the efficiency of raw material pulverization, which in turn affects the efficiency of feed preparation.
