Embodiment 1

[0037] according to figure 1 Shown, a kind of method for the biomodification production feed of restaurant kitchen residue, its steps are as follows:

[0038] (1) Biological preservation of kitchen waste: add 1 kg of Lactobacillus plantarum agent to a kitchen waste collector with a volume of 100 liters. Once kitchen waste is produced, pour it into the collector in time and stir quickly Evenly, and then keep it in a static state until the collector is full; after that, the food waste in the collector is sent to the biological fermentation plant for dehydration and next biological treatment;

[0039] (2), raw material preparation: the preparation raw material is 400 kilograms of water content and be 60% the food and drink of the fresh dining hall (dry food and eating hall kitchen waste is 160 kilograms), be 50% through dehydration water content, be 320 kilograms of water-containing food and drink Canteen kitchen waste, auxiliary material is cotton meal;

[0040] (3), mixed ino...

Embodiment 2

[0048] according to figure 1 Shown, a kind of method for the biomodification production feed of restaurant kitchen residue, its steps are as follows:

[0049] (1) Biological preservation of kitchen waste: add 0.1 kg of compound lactic acid bacteria agent (a mixture of plant Lactobacillus and acidophilus in any proportion) into a kitchen waste collector with a volume of 50 liters. If the residue is generated, pour it into the collector in time and stir it quickly, then keep it in a static state until the collector is full; after that, send the food residue in the collector to the biological fermentation plant for dehydration and drying;

[0050] (2), raw material preparation: the raw material is 200 kilograms of dry food kitchen waste, and the auxiliary material is rapeseed meal;

[0051] (3), mixed inoculation with raw materials and auxiliary materials:

[0052] a, take by weighing 10% of raw material dry weight, namely 20 kilograms of auxiliary material rapeseed meal for su...

Embodiment 3

[0059] according to figure 1 Shown, a kind of method for the biomodification production feed of restaurant kitchen residue, its steps are as follows:

[0060] (1) Biological preservation of kitchen waste: Add 0.5 kg of Lactobacillus acidophilus bacteria agent into a kitchen waste collector with a volume of 150 liters. Once there is food waste, pour it into the collector in time and quickly Stir well, and then keep it in a static state until the collector is full; after that, the food waste in the collector is sent to the biological fermentation plant for dehydration and next biological treatment;

[0061] (2), raw material preparation: prepare raw material to be 1500 kilograms of water content and be 80% catering kitchen waste (300 kilograms of dry meal catering kitchen food), dehydration to water content is 70%, be 1000 kilograms of water-containing food canteen Kitchen waste, auxiliary materials are cotton meal and soybean meal;

[0062] (3) Mixed inoculation of raw materi...

Abstract

The invention relates to a method for producing feeds by modifying kitchen residues of a catering canteen, comprising the following steps of: (1) retaining the freshness of kitchen residue creatures; (2) preparing materials; (3) mixing and inoculating raw materials and auxiliary materials; (4) fermenting; and (5) drying, and processing. The invention ensures the safety of the feeds produced by the kitchen residues, obviously enhances the utilization of the nutritive value of the kitchen residues of the catering canteen, especially enables the protein content to be increased and the amino acid composition to tend to be reasonable, improves the water content of the materials during fermentation and ventilating and radiating functions and ensures that the fermentation is smoothly carried out.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a method for producing feed through biological modification of kitchen waste from restaurants. Background technique [0002] Kitchen waste is a general term for leftovers discarded by families and catering units, and is an important part of urban domestic waste. According to the National Environmental Bulletin, in 2001, the volume of urban domestic waste removal in my country has reached 134.704 million tons, of which kitchen waste removal volume is 40.411 million to 53.882 million tons, accounting for about 30% of the total amount of urban domestic waste. %~50%. [0003] Taking Shenzhen as an example, the amount of kitchen waste generated every day is about 1,600 tons, accounting for about 57% of the city's domestic waste. The main chemical components in kitchen waste are starch, cellulose, protein, lipids and inorganic salts, among which crude protein, crude fi...
