Embodiment Construction

[0009] 1. Mix the collected meal residues and rice husks at a ratio of 6:1 and place them evenly in the maggot raising tank, place the hatched young maggots evenly on the mixing result, observe the growth of fly maggots and the organic matter in the mixing result. For the remaining material, when the fly maggots are about to pupate, the fly maggots are separated to make the raw materials for protein and chitin, and the fly maggots that have not reached the age of pupation are placed on the original mixing result; when the organic matter in the mixing result is After it has been cleaned, the maggots are separated and placed on another batch of the mixing result. This method can be used when the ambient temperature is 0~45°C and the ambient humidity is 15%~90%.

[0010] 2, the same as the previous example, wherein the moisture-absorbing spacer used is the pulverized stalk, and the mixing amount is 1 / 4 of the meal residue, and the separated fly maggots are used as raw materials f...

Abstract

The invention provides a processing method of a food waste. The method comprises the following steps: the food waste and a moisture absorption partition are mixed to obtain a mixture, the mixture which is treated as a bait is eaten by fly larvae, the fly larvae are separated after completing eating, the obtained fly larvae are treated as a raw material for extracting protein and chitin, and residues are treated as a raw material for manufacturing fertilizers. In the present invention, only a place and few energy are needed, other resources are not needed, the pollution to environment is less, the utilization value of obtained by-products is high, for example, the fly larvae can be used for directly manufacturing protein and chitin or after pupating and the residuals can become good organic fertilizers. Compared with the prior art, the method provided by the present invention has the advantages of less consumption, higher processing benefit, and better environmental protection effect.

Description

technical field [0001] The invention relates to a method for treating meal residues, which belongs to the technical field of converting solid waste into useful or harmless things. Background technique [0002] Meal leftovers refer to food discarded due to meals, including waste generated during all processes of food cleaning, preparation and eating. With the increase of population and the improvement of material production capacity, the food consumption of human beings has also increased sharply, and the problem of meal waste disposal has also become more and more serious. Existing treatment methods, the most common are calcination, landfill and bacterial decomposition, such as the Chinese invention patent application "a treatment method for meal waste" (publication number CN101444786) has introduced a method including washing, crushing, pressing And the treatment method of the meal waste that adds microbial strain to carry out the process such as biochemical treatment. Si...
