Problems solved by technology

If it is directly used as feed for pigs, various pathogens and bacteria will spread back to the pigs, and then people will infect people when they eat this kind of pig meat, and if things go on like this, a vicious circle of infection sources will be formed. and residues will clog the sewers and pollute the environment

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] A method for treating catering waste, the basic steps of which are as follows:

[0024] (1) In the sorting step, the catering waste is collected first, then received and stacked, and the catering waste is stored through the storage hopper, which is convenient for stacking and use. A batch of material catering waste is collected and mechanically sorted on the sorting machine first. Sorting, separating objects with a diameter of less than 25 mm, and directly sending them to the cooking step, and objects with a diameter greater than 25 mm are sorted manually through a belt conveyor, and then use magnets to remove iron, including plastics, metals, glass, ceramics , Woody sundries that cannot be used as feed, and then coarsely pulverize the usable materials with a diameter greater than 25 mm with a coarse crusher, crush them into particles w...

Abstract

The invention relates to a processing method of food and beverage waste material, which is characterized in that steps are as follows in sequence: a sorting step, a braising and boiling step, a squeezing step, a drying step, a screening and packing step, wherein, in the braising and boiling step, the food and beverage waste material after the sorting step is braised and boiled for 10 to 30 minutes at the temperature of 35 to 55 DEG C. Partial liquid separated from the squeezing step is separated by a horizontal centrifuge, a separated solid or solid-liquid mixture steps in the drying step, the separated liquid utilizes waste heat in the dry step to concentrate, partial condensed water and exhaust gas are discharged, and then the concentrated liquid is sent to the horizontal centrifuge for circular separation. The technique method is more reasonable, the nutritious substance of food giblets can be fully utilized, and the liquid loss after being squeezed and filtered is prevented, at the same time, environmental pollution is avoided and reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to a method for treating catering waste. Background technique [0002] Kitchen waste refers to food waste and food residues in families, schools, government canteens, and catering industries, and is the main component of municipal solid waste. my country's food waste is large in quantity, high in quality, and mixed, and it is food waste with Chinese characteristics. At present, kitchen waste has become a major public hazard to society. [0003] If the kitchen waste is not handled properly, it will not only endanger people's health, but also seriously pollute the environment. The moisture content of kitchen waste is as high as 80-90%. The seepage water in swill water can easily pollute the ground water through osmosis. When the temperature is high, the organic matter rich in swill will quickly ferment and rot, resulting in Escherichia coli and other pathogenic microorganisms will directly endanger human health. If it is directl...
