Embodiment Construction

[0021] The kitchen waste of the present invention is hotel leftover meals and kitchen waste. The earthworm is the "Taiping No. 1" earthworm produced in Japan. see figure 1 : First put the collected food waste on a vibrating sieve for sieving treatment to remove bones, plastics, iron cans, gravel, and bamboo sticks. The vibrating screen has a vertical amplitude of 1-2cm, a vibration frequency of 800-1000 times per minute, and a sieve hole diameter of 2-3cm. The undersize after removing impurities by the vibrating screen enters the continuous feeding and discharging horizontal centrifuge for centrifugation, and the rotation speed of the continuous feeding and discharging horizontal centrifuge is 2600-2900rmp. The food waste obtained by centrifugation has a water content of 78-82%, an oil content of 1-8% of the food waste (wet weight), and a sodium chloride content of 0.1-0.6% of the food waste (wet weight). Then in the farmland of 20m×20m, excavate 30-80cm deep trenches, each...

Abstract

The invention relates to a method for producing animal protein feed by adopting earthworms to dispose the kitchen garbage. The method comprises the following steps: pre-treating kitchen garbage by sorting to remove impurities and removing oil and fat and sodium chloride to obtain kitchen garbage with an oil and fat content of 1%-8% and a sodium chloride content of 0.1%-0.6%; laying the treated kitchen garbage in a disposal site, and broadcast-sowing earthworms with an earthworm density of 0.5kg/m<2> kitchen garbage; maintaining the temperature in the disposal site at 18 DEG C-25 DEG C and a relative humidity of 50%-75%; carrying out the simple compost of the earthworm cast cleaned out every day to obtain the vegetable nutritional soil; adding the kitchen garbage to the disposal site at a wet weight ratio of the earthworm cast to the kitchen garbage being equal to :(1.5-4) every day; taking out 80-90% earthworms after the earthworms begin to lay eggs in 80-85 days and the new hatched/propagated amount of the earthworm eggs is 9-10 times as that of the broadcast-sowing earthworms in 7-10 days; baking; pulverizing; and granulating to obtain the animal protein feed. The method has the advantages of low basic construction and operation cost, no environment pollution, and high economical and social benefits.

Description

technical field [0001] The invention relates to a method for using earthworms to dispose of kitchen waste to produce animal protein feed, in particular to a method for using mollusk annelid earthworms to dispose of kitchen waste. The invention belongs to the technical field of biodegradation disposal of kitchen waste. Background technique [0002] Kitchen waste is the main component of the organic phase in municipal solid waste, mainly including waste from the catering industry and tailings from the food industry. The channels of its generation are mainly food processing, handling, transportation and other processes, and the sources are mainly concentrated in hotels, food factories, schools, governments, scientific research administrative institutions, etc. Food waste is mainly composed of starch, dietary fiber, animal fat and other substances, and has the characteristics of high moisture content, high oil and salt content, and perishable fermentation and odor. At present,...
