Problems solved by technology

[0003] Although biogas residues are used as raw materials for preparing fish feed at this stage, most of the research and development technical solutions are aimed at exploiting the feeding value of biogas residues and realizing the rational utilization of resources, which are not based on the quality, flavor and nutritional value of fish feed , so that the fish feed prepared at this stage cannot well meet the needs of users in aquaculture

Embodiment 1

[0043] A method for preparing ecological fish feed by enzymatic hydrolysis of biogas residues, specifically comprising the following steps:

[0044](1) After mixing biogas residue, fulvic acid, and peanut seedlings (1 to 3 cm in length) according to the mass percentage of 85:7:8, add yeast and Bacillus subtilis mixed according to the mass ratio of 3:1. Composite enzymatic hydrolysis bacteria agent, piled up and compacted after stirring evenly, sealed and fermented at room temperature (18-27°C) for 45 days to obtain enzymolyzed material; the crushing machine used is "Yunbang 2500 large pulverizer (purchased in Taobao Mall) , The biogas residue was obtained from Zhejiang Yijing Ecological Animal Husbandry Co., Ltd., which was the cow dung and biogas residue after drying in its biogas residue drying cylinder. The initial drying temperature of the drying cylinder was 387 ° C. After drying, the fibers of the biogas residue The element content is 68.78%, and the moisture content of ...

Embodiment 2

[0049] A method for preparing ecological fish feed by enzymatic hydrolysis of biogas residues, specifically comprising the following steps:

[0050] The only difference from the method disclosed in Example 1 is that in the anaerobic fermentation enzymolysis process, the biogas residue, fulvic acid, and peanut seedlings are mixed evenly according to the mass ratio of 80:5:15, and the enzyme is packaged and sealed at 22°C to 36°C Solution 50 days, all the other processing steps and parameters are identical with embodiment 1.

Embodiment 3

[0052] A method for preparing ecological fish feed by enzymatic hydrolysis of biogas residues, specifically comprising the following steps:

[0053] The only difference from the method disclosed in Example 1 is that in the anaerobic fermentation enzymolysis process, the biogas residue, fulvic acid, and peanut seedlings are mixed evenly according to the mass ratio of 82:7:11, and packed at 22°C to 43°C Sealed enzymatic hydrolysis for 50 days, and the rest of the process steps and parameters were the same as in Example 1.

Abstract

The invention discloses a method for preparing ecological fish feed through biogas residue enzymolysis, and relates to the technical field of waste resource utilization and aquaculture. The method comprises the following steps: uniformly mixing biogas residues with fulvic acid and peanut vines, adding a composite enzymatic hydrolysis bacterium preparation, carrying out sealed enzymatic hydrolysis to obtain an enzymatic hydrolysis fermentation material, uniformly mixing the fermentation material with dried orange peel, haws and sesame-seed cakes, carrying out crushing to obtain powder, adding brown sugar, corn starch, soybean meal, calcium powder and tea polyphenols into the powder to form a dough, carrying out steaming, drying and kneading to obtain particle powder, and finally, mixing boiled oil and edible spice, and spraying the mixture on the surface of the particle powder to obtain the fish feed finished product. According to the invention, a biogas residue enzymolysis technology is created, and the granulated particles are sprayed with oil, so that the floating performance of the fish feed particles in water is increased, the fish feed particles are convenient to eat by fishes, the dissolution of the fish feed particles in water is slowed down, and the utilization rate is increased; and in addition, the addition of the dried orange peel, the haws, the sesame-seed cakes and other substances can improve the flavor and nutrition of the product, and the method is suitable for market promotion.

Description

technical field [0001] The invention relates to the technical field of waste resource utilization and aquaculture, in particular to a method for preparing ecological fish feed by enzymolysis of biogas residue. Background technique [0002] With the growth of my country's population and the development of animal husbandry, environmental problems have become increasingly prominent, and the pollution of human and animal manure has become increasingly serious. If it is not treated harmlessly, it will further pollute the soil, water and air, and even spread pathogenic bacteria. It poses a huge threat to the health and life safety of people and animals. At present, the use of biogas anaerobic fermentation technology to treat manure is an effective measure to realize the harmless treatment of manure. The biogas produced by manure treated by biogas anaerobic fermentation technology can be used as energy for production and life after desulfurization treatment, and the biogas slurry pr...
