Method of comprehensively recycling food waste

Abstract

The invention relates to a waste recycling method, in particular to a method of comprehensively recycling food waste. The method comprises the steps of using ozone to disinfect, sterilize, deodorize and retain freshness, and then conducting solid fermentation; and sinking the liquid naturally sink to separate the oil from the water so as to achieve the aim of recycling floating oil and solid fermented feed or organic fertilizer in the food waste. By scientifically treating the food waste and turning waste into wealth, the production of illegal cooking oil is completely eradicated from the source. The method provided by the invention is simple and practicable, the device is simple in structure and easy to manufacture, the secondary pollution is avoided in the treatment process; and according to the method, obvious economic benefits and social benefits are realized.

Description

[0001] technical field [0002] The invention relates to a method for recycling garbage, in particular to a method for comprehensively recycling dining garbage. Background technique [0003] Kitchen waste is the domestic waste formed by residents in the process of living consumption, which is easily rotten and deteriorated, 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 chemical composition, there are starch, cellulose, protein, lipids and inorganic salts. It has the following characteristics: [0004] 1. The appearance is greasy and wet, which affects the comfort and living hygiene of people's vision and smell; [0005] 2. Has a significant duality of waste and resources; [0006] 3. It is difficult to deal with. Under the condition of high temperature, the rate of decay and deterioration is fast, and the long time from produc...

Problems solved by technology

[0006] 3. Difficult to handle

Food waste rots and deteriorates quickly, and it is easy to carry and breed bacteria: foot-and-mouth disease, salmonella, toxoplasma gondii, swine fever bacteria, aflatoxin, etc. Direct use and improper treatment will cause the spread and infection of pathogenic bacteria

Heatless cleaning: Many catering utensils are not cleaned cleanly and are prone to produce toxins and bacteria, which will cause secondary pollution;

[0009] 2. No effective treatment of impurities

Impurities such as metal, glass, ceramics, and sand in the kitchen waste are not cleaned, which brings a lot of disadvantages to the subsequent processing work, easily damages the equipment, makes various raw materials contain more impurities, heavy metals exceed the standard, and product quality is difficult to control

[0010] 3. The means of disinfection and sterilization are backward

The disinfection and sterilization methods used in the prior art, one is high-pressure high-temperature sterilization and drying, the high-pressure high-temperature sterilization equipment is heavy, the energy consumption cost is high, the processing time is long, the floor area is large, there is a certain risk, and the nutritional components are lost , not suitable for mass production, processing and storage; the other is to use chemical raw materials for disinfection and sterilization. The equipment for disinfection and sterilization of chemical raw materials is complicated, the technical requirements and energy consumption are high, the processing time is long, and there is certain corrosion and danger, which will bring Secondary pollution and carcinogens, which do not meet the requirements of green environmental protection, recycling and harmless utilization
