Description
Technical field
The present invention relates to the technical field that solid waste is processed, particularly a kind of sorting of restaurant garbage treating system, cleaning screening, pulverizing and screening discharging technology.
Background technology
Changing food waste mainly refers to the food waste thing that family, dining room, catering trade etc. produce, and is commonly called as swill, is the important part of rubbish in cities and towns; In view of the diet style of China, changing food waste quantity is huge; Because changing food waste contains numerous organic matter compositions, once changing food waste rots, the harm of its generation is inestimable.How effectively changing food waste the mitigation processing, how organic materials is refined and utilizes, and how to reach the efficient processing to changing food waste, has been that each cities and towns environmental sanitation department processes the most important thing of considering to changing food waste at present.
The kitchen castoff Main Ingredients and Appearance comprises rice and flours food residues, vegetables, vegetable and animals oils, meat, bone etc., chemical composition, starch, cellulose, protein, lipid and inorganic salts etc. is arranged.The characteristics of kitchen castoff are that content of organics is abundant, moisture is high, perishable, if do not carry out, reasonably do not dispose in time, not only affect the city appearance of the city and human settlement, and easily grow harmful materials such as pathogenic microorganism, mycotoxin, the harm people's daily life and healthy.
In the prior art, also there is the treatment technology to changing food waste, as the patent No. Chinese patent application patent " a kind of processing method of changing food waste " (notification number is CN101921809A) that is CN201010240492.3; Comprise sorting removal of impurities, the mixture of pulverized particles diameter≤8mm, centrifugation obtain light mutually with heavy phase, will obtain gently be centrifugated into mutually grease and highly concentrated solution, aquation making beating and acidifying: heavy phase and highly concentrated solution water mill are made to underflow and the acidifying that is hydrolyzed obtains in base-material, upflow anaerobic sludge blanket process carrying out anaerobic fermentation and obtains biogas to underflow.This design is not cleaned the high temperature of solids carrying out in the garbage sorting process, and the waste residue thing surface adhesion of discharging has more organic materials, and this is unfavorable for the more collection of organic component; When further organic materials is processed, do not introduce the high temperature water-washing method, be unfavorable for the recovery of organic materials during to the secondary removal of impurities, reduce actual processing effect.
Summary of the invention
Technical problem to be solved by this invention is the present situation for prior art, provide a kind of flow scheme design rationally, process safety, aquation fusion amount large, clean up, stable and do the restaurant garbage treating system that efficiency is high sorting, clean screening, pulverize and the screening discharging technology.
