Embodiment 1

[0020] A kind of method utilizing Tenebrio molitor to process kitchen waste, comprises the following steps:

[0021] (1) Collect food waste, and manually sort and remove large bones, plastic bags, paper towels, toothpicks, and bamboo chopsticks;

[0022] (2) Rinse the food waste with water to reduce its salinity and remove part of the fat; grind the washed food waste into a fine slurry (particle size is about 1-5mm), quickly carry out high-temperature steam sterilization, and then high temperature Drying to obtain dry food waste powder;

[0023] The obtained aseptic dry food waste powder has a salinity of 0.91%, a crude fat content of 5.4%, and a water content of 13%;

[0024] (3) get the mixing of 60% kitchen waste dry powder and 40% wheat bran, be made into Tenebrio molitor culture medium; Described percentage is the percentage that accounts for the total mass of Tenebrio molitor culture medium;

[0025] The obtained Tenebrio molitor culture medium has a crude protein cont...

Embodiment 2

[0029] A kind of method utilizing Tenebrio molitor to process kitchen waste, comprises the following steps:

[0031] (2) Rinse the food waste with water to reduce its salinity and remove part of the fat; grind the washed food waste into a fine slurry (particle size is about 1-5mm), quickly carry out high-temperature steam sterilization, and then high temperature Drying to obtain dry food waste powder;

[0032] The obtained aseptic dry food waste powder has a salinity of 0.85%, a crude fat content of 5.5%, and a moisture content of 12%;

[0033] (3) get 75% kitchen waste dry powder and mix with 25% wheat bran, be made into Tenebrio molitor culture medium; Described percentage is the percentage that accounts for the total mass of Tenebrio molitor culture medium;

[0034] The obtained Tenebrio molitor culture medium has a crude protein conten...

Embodiment 3

[0038] A kind of method utilizing Tenebrio molitor to process kitchen waste, comprises the following steps:

[0039] (1) Collect food waste, and manually sort and remove large bones, plastic bags, paper towels, toothpicks, and bamboo chopsticks;

[0040] (2) Rinse the food waste with water to reduce its salinity and remove part of the fat; grind the washed food waste into a fine slurry (particle size is about 1-5mm), quickly carry out high-temperature steam sterilization, and then high temperature Drying to obtain dry food waste powder;

[0041] The obtained sterile food waste dry powder has a salinity of 0.95%, a crude fat content of 5.6%, and a water content of 15%;

[0042] (3) get the mixing of 90% kitchen waste dry powder and 10% wheat bran, be made into Tenebrio molitor culture medium; Described percentage is the percentage that accounts for the total mass of Tenebrio molitor culture medium;

[0043] The obtained Tenebrio molitor culture medium has a crude protein cont...

Abstract

The invention discloses a kitchen waste treatment method by utilizing mealworms, which comprises the following steps: collecting kitchen waste, artificially sorting and rejecting large bones, plastic bags, tissues, toothpicks and bamboo chopsticks; washing the kitchen waste with water, crushing the washed kitchen waste into fine pulp, subjecting the crushed chicken waste to high-temperature steam sterilization, drying the waste at a high temperature, and obtaining chicken waste dry powder; mixing 60% to 90% of the chicken waste dry powder with 10% to 40% of wheat bran to obtain mealworm culture medium; the percentage is a percentage accounting for the total weight of the mealworm culture medium; and using the mealworm culture medium to feed the mealworms. According to the kitchen waste treatment method, kitchen waste is sterilized and is produced into dry powder, not only purposes of convenient transportation and long time preservation are achieved, but also reduction and harmlessness treatments of the kitchen waste are achieved; and the mealworm culture medium mixed by the kitchen waste dry powder and the wheat bran is used to cultivate mealworms, thereby not only placement problem of the kitchen waste is solved, but also the kitchen waste is changed into treasure, and reutilization of the kitchen waste is achieved.

Description

technical field [0001] The invention relates to a treatment method for kitchen waste, in particular to a method for treating kitchen waste with Tenebrio molitor. Background technique [0002] my country is the most populous country in the world. With the acceleration of urbanization, the amount of municipal solid waste is also increasing rapidly. At present, the stock of garbage piles in my country has reached 6 billion tons over the years. In the composition of urban domestic garbage in China, the proportion of kitchen waste is about 37-62%. According to statistics, in 2000, the amount of food waste produced in my country was 45 million tons, and it increased at an annual rate of about 10%, and the annual increase in the amount of food waste generated reached 5 million tons. At present, the management of food waste in most cities in my country is basically blank, and the emission units are in a state of self-disposal. This has directly led to three main flows of food wast...
