Feed formula capable of promoting growth of fishes and shrimps as well as production process and equipment

Abstract

The invention relates to the technical field of fish and shrimp feed production, and particularly discloses a feed formula capable of promoting fish and shrimp growth and a production process and equipment. The feed formula comprises the following components in parts by weight: 150-165 parts of soybean meal, 26-30 parts of corn flour, 20-25 parts of rapeseed meal, 18-25 parts of bone meal, 12-18 parts of fish meal, 8-12 parts of earthworm powder, 4-6 parts of Chinese herbal medicine powder, 2-4 parts of beer yeast and 2-5 parts of a compound vitamin premix; the preparation equipment comprises a rack, a steam generation device, a steam conditioner and an extrusion granulator. According to the feed disclosed by the invention, various feed raw materials which are reasonable in proportion and balanced in nutrition are adopted, and then the feed raw materials are steamed by the steam conditioner before extrusion granulation, so that nutritional ingredients in the feed raw materials are cooked, the utilization rate of the feed by fishes and shrimps is greatly increased, and rapid growth of the fishes and shrimps is effectively ensured; the whole preparation equipment has novel structural design, excellent steam conditioning effect on the feed and high practicability.

Description

technical field [0001] The invention relates to the technical field of fish and shrimp feed production, and specifically discloses a feed formula capable of promoting the growth of fish and shrimp, a production process and equipment. Background technique [0002] Fish and shrimp are the most common aquatic products in our country. During the breeding process of fish and shrimp, feed needs to be put in. On the one hand, the feed can promote the growth of fish and shrimp, and on the other hand, it can improve the immunity of fish and shrimp. However, most of the feeds currently on the market are uniformly composed of soybean meal, bone meal and other components. Although the nutritional content is relatively excellent, the production process of the feed is insufficient, resulting in a low feed utilization rate and slow production of fish and shrimp. [0003] For example, the invention patent with the application number 2017114699903 discloses a high-nutrition fish and shrimp f...

Problems solved by technology

However, most of the feeds currently on the market are composed of soybean meal, bone meal and other components. Although the nutritional content is relatively excellent, the production process of the feed is insufficient, resulting in a low feed utilization rate and slow production of fish and shrimp.

[0003] For example, the invention patent with the application number 2017114699903 discloses a high-nutrition fish and shrimp feed, which contains: bone meal 40-60%, soybean meal 10-15%, brewer’s yeast 2-8%, cornstarch 10-15%, Spirulina powder 6-10%, kelp powder 8-15%, mugwort leaf powder 1-2%, multivitamin premix 1-3%, mineral premix 1-3%; A variety of balanced feed materials are processed through crushing, premixing, granulation, oiling, drying, cooling and other steps. The preparation cost is low, but the soybean meal and rice starch in the feed are not overcooked. Lead to low utilization rate of nutrients in fish and shrimp during eating

[0004] In addition, there are many feed steam conditioners in the market at present, but the steam nozzle of this type of steam conditioner is easy to be blocked when the feed material is steamed
