NOVELTY - Processing kitchen waste involves subjecting the waste to mechanical pre-processing; separating iron from it, crushing remaining portion and separating using a sieve, to obtain small diameter material that comprises e.g. bone, rice, vegetable, bone, soup; subjecting it to solid cooking and pressing to remove oil and water; biological treatment by fly maggot breeding to convert the waste into biological organic fertilizer that is dried, separated and granulated.    USE - For converting kitchen waste into biological organic fertilizer (claimed)    ADVANTAGE - The present process doesn't provide environment pollution; saves the energy; effectively uses kitchen waste; eliminates the need of high temperature drying and granulating; improves the level of the product; and solves the problem that the homology is to feed kitchen waste.    DETAILED DESCRIPTION - Processing a kitchen waste involves: a) mechanical pre-processing that involves transporting kitchen waste collected, directly into a treatment site of material receiving tank, subjecting it to bag breaking mechanism to release the kitchen waste, transporting it to a cleaning tank, adding cleaning liquid to remove a part of grease, and loose raw material; b) Passing pre-treated waste through a metal removing device, to remove metal such as iron, aluminum, stainless steel, crushing separated waste in a crusher, separating part with small diameter material that comprises bone, rice, vegetable, bone, soup and transporting it through lower track processing technique, and washing large diameter material that comprises plastic bag, lunch box, a glove with a hot cooking liquor and drying to obtain the clean waste plastic, lunch box, and then manually sorting; c) subjecting the small diameter material to solid cooking and oil pressing so as to remove water and grease; d) treating resulting solid in a horizontal oil-slag separating machine for mechanically separating, to obtain the water 10% at the left and oil, hot cooking liquor and residue on the right side; e) performing mixed fermentation to obtain edible maggot biological feed that includes impurities, including wood chips, glass pieces, soil and so on; f) carrying out fly maggot breeding on the material as biological feed, to obtain clean fresh maggot and biological organic fertilizer; g) subjecting fresh maggot to drying and with low and normal temperature drying method; and h) granulating the resulting biological organic fertilizer.
