Problems solved by technology

However, in the feed preparation process of this invention, solvent extraction is used to remove residual oil, although the oil content is reduced, but it will inevitably lead to solvent residue; at the same time, the active substances in the raw materials are almost completely lost during the processing.

Embodiment 1

[0023] A method for preparing breeding feed using kitchen waste, comprising the following steps:

[0024] (1) Removal of impurities: Manually remove plastic, toothpicks, chopsticks, and metal impurities from the recycled kitchen waste, and set aside;

[0025] (2) Centrifugation: centrifuge the food waste after removing impurities in step (1) in a 3000r / min centrifuge for 10min;

[0026] (3) Water washing: add drinking water according to the material-to-liquid ratio of 1:2, rinse the kitchen waste in step (2), centrifuge at 3000r / min for 10min after washing, wash twice, and obtain the washed kitchen raw materials after centrifugation, for subsequent use;

[0027] (4) Squeeze: use a twin-screw squeeze dehydrator to remove the moisture in the kitchen raw materials after washing, so that the final moisture content of the material is less than 60%;

[0028] (5) High-temperature sterilization: put the squeezed material into a cooking pot and heat it to 100°C, and boil it for 25 min...

Abstract

The invention belongs to the technical field of treatment of kitchen wastes and in particular relates to a method for preparing breeding feed by utilizing kitchen wastes. The breeding feed is prepared by the following steps: removing impurities, centrifuging, washing, squeezing, performing high-temperature sterilization, mixing and blending, cooking and sterilizing, fermenting, performing microwave pretreatment, low-temperature drying, grinding and screening. The kitchen wastes are taken as raw materials and are mixed with broken corn and rice bran, and the content of nutritional ingredients in the feed is increased. In the fermentation process, aspergillus niger, saccharomycetes, bacillus natto and bacillus subtilis are selected as microbial fermentation strains, multiple enzymes such as cellulase, xylanase, beta-dextranase, amylase and protease produced by microbes are fully utilized, the enzyme system in the animals is obviously improved, endogenous enzyme insufficiency is overcome, the gastrointestinal functions are improved, and the digestive absorption capacity is enhanced. A method for combining microwave drying with low-temperature low-humidity drying is adopted in the drying process, and the activity of each kind of nutrition in the feed is guaranteed in the drying process, so that the final product is high in biological activity and content.

Description

technical field [0001] The invention belongs to the technical field of catering waste treatment, and relates to a method for processing aquaculture feed, in particular to a method for preparing aquaculture feed with kitchen waste. Background technique [0002] Kitchen waste, commonly known as swill, is the domestic waste formed by residents in the process of living consumption. It is easy to rot and deteriorate, emits foul smell, and spreads bacteria and viruses. The main components of food waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc. From the perspective of chemical composition, they are rich in organic matter, including starch, cellulose, protein, lipids and inorganic salts. Its main features are rich in organic matter, high in moisture content, and perishable. Its properties and odor will have a bad impact on environmental sanitation, and it is easy to breed harmful substances such as pathogenic microorganisms and...
