Abstract

The invention relates to a method for producing a protein feed by using food and drink waste, which comprises the following steps: 1) pretreating food and drink wastes, removing foreign matter and impurity, such as metal and stone, 2)adding 15-30% of wheat bran as an ingredient for beating, controlling the moisture content at 40-50% after beating; 3)disinfecting; 4)inoculating one or more of candida utilis, brewers yeast and plant lactobacillus, fermenting for 24-30 hours at 30-35 DEG C; 5)drying at 60-70 DEG C, wherein the moisture content at drying point is 10-15%; 6) forming to obtain the long particles with 1-2 cm; and 7) packaging. The method has the beneficial effects that the protein feed is produced by the food and drink waste, the food and drink wastes can be fully used, so that waste is changed into valuables, and the protein demand pressure is reduced. The method has the advantages of mild reaction condition, low equipment requirement, and convenient and feasible operation.

Description

technical field [0001] The invention relates to the field of energy reuse, in particular to a method for producing protein feed by using catering waste. Background technique [0002] The shortage of protein resources is a major issue facing the world. According to the estimates of the Food and Agriculture Organization of the United Nations, the human demand for protein will be more than 200 million tons per year in the first ten to twenty years of this century. Domestically, with the rapid development of the aquaculture industry, there is a shortage of protein feed, and the contradiction between humans and animals competing for food has become increasingly prominent. In 2005, the import of fishmeal alone reached 1.6 million tons, costing 1.2 billion US dollars in foreign exchange. [0003] Catering waste belongs to special garbage, which contains a lot of nutrients, and the main components are starch, protein and oil. Because of its rich nutrition, untreated catering waste...
