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
The present invention relates to the processing method of changing food waste, be specifically related to a kind of yellow meal worm method for processing utensil rubbishes of utilizing.
Background technology
China is the maximum country of world population, and along with quickening of urbanization process, the quantity of domestic waste is also increasing sharply.At present, China's rubbish heap storage over the years has reached 6,000,000,000 tons, and in China's domestic waste constituted, the ratio of changing food waste was about 37-62%.According to statistics, China's changing food waste generation was 4,500 ten thousand tons in 2000, and with the speed increase in every year about 10%, a year newly-increased changing food waste generation reaches 5,000,000 tons.And China's most city is in blank basically to restaurant and Kitchen Swill Management at present, the state that the discharging unit disposes voluntarily.This has directly caused three main flow directions of changing food waste: one of which, and most of unprocessed, being collected directly raises chickens feeds pigs; Its two, few part changing food waste is drawn refinement " swill oil " to return to dining table by the people; Its three, the part changing food waste mixes through classification and other domestic wastes and gets into the garbage collecting and transferring system or directly pour the urban sewage system into.
More than these processing modes not only brought food-safety problem, therefore the also entail dangers to people's physical and mental health, and increased the garbage disposal difficulty has caused social extensive concern.Set up the effective management system of changing food waste and develop the technology of administering efficiently very urgent.
From the viewpoint of environmental protection, changing food waste is a kind of pollution, and from the angle of the utilization of resources, this is a kind of resource.If can Unified Treatment be carried out in its collection in the urban planning, not only alleviated the problem of garbage-surrounded city, and can turn waste into wealth.
Summary of the invention
In order to overcome the problem that exists in the existing changing food waste processing; The object of the present invention is to provide the method for utilizing yellow meal worm fast processing city changing food waste that a kind of processing procedure is simple, cost is low; This method organically combines the processing of changing food waste and the breed of yellow meal worm; Not only alleviate the problem of garbage-surrounded city, and can turn waste into wealth, realized changing food waste minimizing, innoxious, recycling treatment.
The object of the invention is realized through following technical proposals:
A kind of yellow meal worm method for processing utensil rubbishes of utilizing may further comprise the steps:
(1) collect changing food waste, and the manual sorting rejects materials such as bulk bone, polybag, paper handkerchief, toothpick and bamboo chopsticks;
(2) water flushing changing food waste is to reduce its salinity and to remove part fat; Changing food waste after the flushing is ground into screened stock shape (particle diameter is about 1-5mm), carries out the high-temperature steam sterilization rapidly, high temperature drying obtains kitchen waste dry powder again;
Resulting kitchen waste dry powder salinity≤1%, crude fat content≤7%, water content≤15%;
(3) get 60～90% kitchen waste dry powder and mix, be made into the yellow meal worm culture medium with 10～40% wheat bran; Described percentage is the percentage that accounts for yellow meal worm culture medium gross mass;
Resulting yellow meal worm culture medium, crude protein content are 46～58%, crude fiber content 12～26%, and crude fat content 4～6%, coarse ash content 10～16%, other is moisture and impurity, said percentage is mass percent;
(4) with the yellow meal worm culture medium yellow meal worm (Tenebrio molitor) that is used to feed.
The yellow meal worm of being fed by this culture medium grows fine, preceding 21 days yellow meal worm daily gains 4～9%, and the average reduction rate of culture medium is more than 85%.
The present invention has following advantage and effect with respect to prior art:
1, the present invention with changing food waste fast processing, sterilization, process dry powder; Changing food waste without putrefaction, long purpose of holding time had both been reached; Realize minimizing, the harmless treatment of changing food waste again, also helped the further processing of changing food waste simultaneously.
2, kitchen waste dry powder and wheat bran are mixed and made into the yellow meal worm culture medium, have both handled changing food waste efficiently, again successfully cultured yellow meal worm.When solving the placement issue of present changing food waste, develop a kind of new resource again, turned waste into wealth, realized the purpose of changing food waste into resources.The protein additive that the yellow meal worm of culturing not only can be used as animal feed also can extract active component and be used for field of medicaments.
