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 with reference to the embodiments of the accompanying drawings.

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

[0024] (1) Sorting step, first collect catering waste, then pick up and stack, store catering waste through the storage hopper, which is convenient for stacking and use, collect a batch of catering waste, and first carry out mechanical processing on the sorting machine Sorting, separating objects with a diameter of less than 25 mm and sending them directly to the cooking step; objects with a diameter greater than 25 mm are manually sorted through a belt conveyor, and then iron is removed by a magnet, including plastics, metals, glass, and ceramics. , Wood can not be used as feed debris, and then the available materials with a diameter greater than 25 mm are coarsely pulverized with a coarse pulverizer, and pulverized into particles with a diameter of less ...

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 food and beverage waste. Background technique [0002] Food waste refers to food waste and food residues in households, schools, public canteens, and the catering industry, and is the main component of urban domestic waste. my country's food waste is large in quantity, high in quality, and has many impurities. It is food waste with Chinese characteristics. At present, kitchen waste has become a major public hazard in 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 the swill water can easily pollute the ground water through osmosis. The organic matter rich in the swill will quickly ferment and rot when the temperature is high, resulting in Escherichia coli and other pathogenic microorganisms will directly endanger human hea...
