Embodiment 1

[0017] A method for preparing protein feed using catering waste, which includes: 1. Pretreatment of catering waste: removing impurities and a large amount of water; 2. Heat and sterilize the pretreated catering waste, that is, boil for 30 minutes; 3. Add the catering waste obtained after sterilization to ferment with strains at a temperature of 35°C for 2 days, and stir from time to time. The strains are lactic acid bacteria; 4. Filter the catering waste obtained after fermentation, and take the filter residue to dry to obtain protein feed . Add other nutrients to protein feed to make compound feed.

Embodiment 2

[0019] A method for preparing protein feed using catering waste, which includes: 1. Pretreatment of catering waste: removing impurities and a large amount of water; 2. Heat and sterilize the pretreated catering waste, that is, boiling for 45 minutes; 3. Add the catering waste obtained after sterilization to ferment with strains, ferment at 38°C for 3 days, and stir from time to time, the strain is yeast; 4. Filter the catering waste obtained after fermentation, take the filter residue and dry to obtain protein feed. Add other nutrients to protein feed to make compound feed.

Embodiment 3

[0021] A method for preparing protein feed using catering waste, which includes: 1. Pretreatment of catering waste: removing impurities and a large amount of water; 2. Heat and sterilize the pretreated catering waste, that is, boil for 35 minutes; 3. Add the catering waste obtained after sterilization to ferment with strains at a temperature of 7°C for 2.5 days, and stir from time to time. The strains are lactic acid bacteria and yeast; 4. Filter the catering waste obtained after fermentation, and take the filter residue to dry. That is protein feed. Add other nutrients to protein feed to make compound feed.

Abstract

The invention relates to the field of fodder, in particular to a method for preparing protein fodder by using catering waste materials. The method comprises the following steps: 1, pretreating the catering waste materials: removing impurities and a great amount of moisture; 2, allowing catering waste materials already subjected to pretreatment to be subjected to heating and sterilization; 3, adding a strain in the sterilized catering waste materials for fermentation; 4, filtering the fermented catering waste materials, and drying filter residues to obtain the protein fodder, wherein the strain is one or a combination of lactic acid bacteria or saccharomycetes; during the process of heating and sterilization, the catering waste materials are boiled for 30-45 min; the fermentation conditions include that the temperature is 35-38 DEG C, the time is 2-3 d, and stirring is performed from time to time. The method has the benefits that the catering waste materials are made into the fodder by adding the strain for fermentation, thereby turning waste into wealth to avoid illegal cooking oil being used again to affect people health. On the other hand, as the catering waste materials are low in cost, the method is simple and feasible, and has no high requirements on equipment. Moreover, the required protein fodder prepared is low in cost.

Description

technical field [0001] The invention relates to the field of feed, in particular to a method for preparing protein feed from catering waste. Background technique [0002] my country's swill resources are very rich, and large collective catering units such as restaurants, hotels, schools, and government agencies in cities have a large amount of swill mixed with leftover meals every day, and its quantity is large and concentrated. If these kitchen wastes are not disposed of in time, they will rot and deteriorate, producing a large number of bacteria and harmful gases (especially in hot summer), causing pollution to environmental sanitation. [0003] Although the catering waste has high water content and low nutrient concentration, its dry matter contains high fat content, among which crude fat reaches 14.26%. The total energy level is up to 20MJ / Kg, the crude protein is about 20%, the carbohydrate is about 60%, and the organic matter is about 90%. In addition to conventional...
