Problems solved by technology

[0006] (2), high moisture content
[0007] The moisture content of food waste is generally 70-90%. It is highly fluid and easy to leak, which brings great difficulties to the collection, transportation and treatment of food waste.
Garbage seepage can pollute surface water and groundwater through surface runoff and infiltration, and because the calorific value per unit mass of food waste is about 2100 kJ / kg, it cannot meet the calorific value requirements of waste incineration power generation
[0008] (3), large amount of production
[0010] (4), perishable
According to research and analysis, due to the extensive use of detergents, disinfectants and insecticides in restaurants and toxins produced by food mildew, the swill contains a large amount of toxic and harmful substances such as lead, mercury, and Aspergillus flavus. After pigs eat swill, these substances will be in the Pigs gradually accumulate in the body and enter the human body through the food chain. The human body does not have the function of disinfection and elimination of these substances. After reaching a certain level, it will damage the human nerves, liver, kidneys and immune system, etc.
[0017] (2), pollute the environment
[0019] (3) Affecting urban appearance and environmental sanitation
This method has simple process, low operating cost, and less secondary pollution; however, the high content of oil and salt in the kitchen waste is not conducive to the growth of microorganisms and restricts the effect of microbial treatment technology; in addition, microbial fermentation requires the guarantee of various conditions such as Moisture, ventilation, organic matter content, salt content, carbon and nitrogen ratio, etc., and the production cycle is long, which cannot meet the requirements of the manufacturer

Embodiment 1

[0053] Embodiment 1: Take laboratory production as an example (get 10 kilograms of kitchen waste).

[0054] The first step: washing with water;

[0055] Put 10 kg of food waste collected by restaurants into a stainless steel pot with a drain valve at the bottom (referred to as No. 1 pot), open the drain valve at the bottom to drain the hogwash and move it to another stainless steel pot with a drain valve at the bottom ( That is, the oil-water separation pot, referred to as No. 2 pot).

[0056] In the No. 1 pot, the material (about 6 kg) after the water discharge is added to 6 kg of 5% NaCl aqueous solution at 40 ° C, and the gas valve connected to the air compressor at the bottom is opened (gas terminal pressure 5 kg / m 2 ), turn the material with air pressure, stir for 30 minutes, and then let it stand for 1 hour, then open the water valve at the bottom, release the washing liquid and move it to the No. 2 pot. The material after water separation is sent out for sorting.

Embodiment 2

[0071] Example 2: Take a kitchen waste treatment plant that processes 50 tons of kitchen waste per day as an example:

[0072] The first step: washing with water;

[0073] Transport 50 tons of food waste collected by the restaurant to the water-splitting washing tank, open the bottom drain valve to discharge the water (soil) and move it to the oil-water separation tank, and add 40 °C to the water-separating washing tank 30 tons of 5% NaCl aqueous solution, open the gas valve connected to the air compressor at the bottom (the gas terminal pressure is 5kg / m 2 ), stirred with air for 30 minutes, and left to stand for 1 hour. Then open the water discharge valve at the bottom, discharge the washing liquid and move it to the oil-water separation tank, and transport the dehydrated materials to the sorting equipment for sorting.

[0074] The second step: sorting;

[0075] The materials that have been separated from the water in the first step and washed with water are sent to the f...

Abstract

The invention relates to a method for preparing a feed by carrying out high-temperature curing and leaching on kitchen waste, belonging to the technical field of solid waste recycling. The method comprises the following steps of: carrying out water distribution on kitchen waste, adding appropriate electrolytical aqueous solution for washing so as to wash a cleaning solution and most microorganismfermentation products out, then sorting, curing, squeezing, drying, extracting with a plant oil extracting solvent to extract oil and other fat-soluble substances, and then drying for killing microorganism to obtain the thoroughly purified protein feed product. By adopting the method provided by the invention, the kitchen waste can be thoroughly purified, kitchen waste resource is recycled, the extracted oil is taken as a raw material of biodiesel and detergent, and pigwash residues are prepared into raw material of feed; the problems that the existing kitchen waste is directly used for feeding livestock and poultry without being treated, harmful substances in the livestock and poultry are accumulated to indirectly bring harm to human health and the human health is threatened can be solved, thus the method has extremely important economic and social benefits.

Description

Technical field: [0001] The invention relates to a method for preparing feed by high-temperature aging and leaching of kitchen waste, which belongs to the technical field of solid waste resource treatment. Background technique: [0002] Food waste, commonly known as swill, refers to food residues and wastes produced in activities other than daily life, such as food processing, catering services, and unit meals. It is mainly organic matter such as starch, dietary fiber, fat, and protein, and is easily corrupted. Fermentation, smelly and other characteristics, if not properly managed and handled properly, will cause environmental pollution and threaten the health of the people. However, since food waste contains a large amount of organic matter, it has the value of reuse after scientific treatment. Therefore, food waste has the duality of recycling and pollution. [0003] Food waste has the following characteristics: [0004] (1), containing waste animal and vegetable oils ...
