preparation example Construction

[0023] A method for preparing organic feed using kitchen waste as raw material, comprising the following steps in sequence:

[0024] Preparation of microbial fermentation composition: first mix the combined enzyme agent, microbial mixed bacterial agent and water according to the required ratio to form a degradation liquid, then add food waste to the degradation liquid and mix to obtain a mixed material, and then in 25- Aerobic fermentation at 50°C for 8-12 hours to obtain the microbial fermentation composition;

[0025] The preparation of the organic feed: first crush the microbial fermentation composition, and then mix it with soybean powder and calcium hydrogen phosphate according to the required ratio.

[0026] The fermentation temperature is maintained at 35-45°C.

[0027] During the whole aerobic fermentation process, the air with an oxygen concentration of 10%-20% is continuously introduced from the bottom of the mixed material.

[0028] The preparation method also inc...

Embodiment 1

[0042] An organic feed using kitchen waste as raw material, its raw material composition and weight ratio are: soybean powder 15, microbial fermentation composition 50, calcium hydrogen phosphate 0.5, wherein, the raw material composition and weight of the microbial fermentation composition The ratio of parts is: 0.5 of microbial mixed bacterial agent, 1 combined enzyme agent, 100 of kitchen waste, and 20 of water. For Aspergillus niger and Aspergillus oryzae, the inoculation amount of each bacterium is 0.2% of the weight of kitchen waste, and the combined enzyme agent is 5000U / g protease, 1000U / g cellulase, 3000U / g glucanase, 2000U / g A mixture of pectinase and 10000U / g lipase.

[0043] The preparation method of above-mentioned organic feed carries out according to the following steps successively:

[0044] The pre-treatment of food waste is: using a solid-liquid separator to squeeze and dehydrate the food waste;

[0045] Preparation of microbial fermentation composition: fi...

Embodiment 2

[0048] The difference with Example 1 is:

[0049] The raw material composition and weight ratio of the bio-organic fertilizer are: soybean powder 25, microbial fermentation composition 65, calcium hydrogen phosphate 1, wherein, the raw material composition and weight ratio of the microbial fermentation composition are: microbial mixed bacteria Agent 0.8, combined enzyme agent 0.6, kitchen garbage 100, water 23, the inoculum size of each strain in the described microbial mixed bacterial agent is 0.3% of the food garbage weight, and described combined enzyme agent is 6000U / g protease, A mixture of 2000U / g cellulase, 5000U / g glucanase, 4000U / g pectinase and 12000U / g lipase.

[0050] In the preparation step of the microbial fermentation composition, the aerobic fermentation temperature is kept at 35-45° C., and the fermentation time is 8 hours.

Abstract

The invention relates to an organic feed taking kitchen waste as a raw material. The feed comprises the following raw materials in parts by weight: 15-30 parts of bean powder, 50-80 parts of a microbial fermentation composition and 0.5-1 part of calcium hydrophosphate. The microbial fermentation composition is obtained by performing aerobic fermentation on a microbial mixed agent, a combined enzyme agent, kitchen waste and water at a weight ratio of (0.5-1):(0.5-1):100:(20-30) at 25-50 DEG C for 8-12h. The microbial mixed agent comprises the following raw materials: bacillus subtilis, bacillusmegaterium, bacillus cereus, bacillus licheniformis, aspergillus niger and aspergillus oryzae; and the combined enzyme agent is a mixture of protease, cellulase, glucanase, pectinase and lipase. Thedesign not only realizes the deep degradation of organic matters, is beneficial to improving the immune function in animals, but also has short fermentation period, and does not generate stink.

Description

technical field [0001] The invention belongs to the field of organic feed, and in particular relates to an organic feed using kitchen waste as a raw material and a preparation method thereof. Background technique [0002] As an important part of biomass, food waste is rich in protein, fat and various trace elements, which fully meets the basic requirements of it as a feed raw material, and it is relatively concentrated, so it is easier to treat it as a centralized resource. Food waste is generally produced in the canteens of families, schools, and units, as well as the catering industry. According to the survey, there are about 4.7 million large and small restaurants in my country at present, and the total monthly output of kitchen waste reaches 134,000 tons, which is a huge amount. Therefore, the resource utilization of kitchen waste can not only make up for the resource gap in our country to a certain extent, but also improve the increasingly serious environmental sanitat...
