Problems solved by technology

[0005] The technical problems mainly solved by the present invention are as follows: in view of the surprising amount of kitchen waste produced every year, abandonment or incineration or sanitary landfill treatment will bring unavoidable harm to the environment and land resources, and today’s eggs are easy to break, and Although the existing egg protection shell has a certain protection ability, the material is basically non-degradable by itself, and the compression resistance is relatively weak, which will still cause the problem of eggs being broken. This provides a kind of food waste added blue-green algae fiber A method for preparing a degradable egg protection box, the method uses kitchen waste as a raw material, firstly the collected kitchen waste is dried, crushed and cooled, then put into a pot, fermented together with herbs and water, and then Chopped cyanobacteria, added cellulase for enzymatic hydrolysis, mixed the enzymatically hydrolyzed cyanobacteria and kitchen waste fermentation mixture and fermented again to obtain a paste-like substance, and finally used the obtained paste-like substance to make egg protection shells

example 1

[0020] 5g of recovered kitchen waste was stirred and cleaned once with weak alkali waste liquid, spread evenly on the ground, dried naturally in the sun, put into a pulverizer for crushing, and passed through a 100-mesh sieve to obtain kitchen garbage. Garbage powder; put the above-mentioned kitchen garbage powder into a steam cage, pass superheated steam at 100°C into it, steam for 8 minutes, and cool naturally at room temperature of 18°C ​​for 1.5h; take 10g Dipsacus and 15g gallnut , 12g nightshade nightshade and 5g raspberry were put into a jet mill for micron-scale superfine grinding to obtain a 10 μm herbal medicine mixed powder, and then the herbal medicine mixed powder and distilled water were put into an iron pot with a diameter of 80 cm according to the solid-to-liquid ratio of 2:9 Add the above-mentioned cooled kitchen waste powder to the iron pot at the same time, stir evenly, cover the pot, wrap it with a quilt, and ferment at 35°C for 10 days; take 500g of fresh ...

example 2

[0023]8 kg of recovered kitchen waste was stirred and cleaned twice with weak alkali waste liquid, then evenly spread on the ground, dried naturally in the sun, put into a pulverizer for crushing, and passed through a 130-mesh sieve to obtain kitchen garbage. Garbage powder; put the above-mentioned kitchen garbage powder into a steam cage, pass superheated steam at 130°C into it, steam for 12 minutes, and then cool naturally at room temperature of 19°C for 2 hours; take 20g Dipsacus and 18g gallnut Put 15g black nightshade and 8g raspberry into a jet mill for micron-scale ultrafine grinding to obtain a 13 μm herbal powder mixture, then put the herbal powder mixture and distilled water into an iron pot with a diameter of 90 cm according to the solid-to-liquid ratio of 2:9 , and add the above-mentioned cooled kitchen waste powder into the iron pot at the same time, stir evenly, cover the pot, wrap it with a quilt, and ferment for 13 days at 40°C; take 650g of fresh blue-green alg...

Abstract

The invention discloses a method for preparing a degradable egg protection box by adding cyanobacteria cellulose in kitchen garbage, and belongs to the technical field of daily life garbage processing.Kitchen garbage is used as the raw material, collected kitchen garbage is air-dried, smashed and cooled first and then put in a pot to be fermented together with Chinese herbal medicine and water, cyanobacteria is taken and cut into pieces, cellulose is added for enzymolysis, a cyanobacteria and the kitchen garbage fermented mixture obtained through enzymolysis are mixed and fermented again to obtain paste substances, and finally an egg protection shell is made from the paste substances.The method proves that the problem of pollution caused by the kitchen garbage to the environment is solved, soil occupation is reduced, the huge cost for processing life garbage is saved, and meanwhile the aim of turning waste into wealth is achieved; in addition, the manufactured egg protection shell can be degraded by itself, the impact resistance is high, eggs can be protected, and the egg damage rate is decreased by 60% or above.

Description

technical field [0001] The invention discloses a method for preparing a degradable egg protection box by adding cyanobacteria cellulose to kitchen waste, and belongs to the technical field of daily life waste treatment. Background technique [0002] Domestic waste is generally divided into recyclable waste, non-recyclable waste and hazardous waste. These wastes cause many harms to human life and the environment. A large amount of pollutants such as ammonia and sulfide are released into the atmosphere, which contain more than 100 kinds of organic volatile gases. White pollution". [0003] Kitchen waste is the most common waste gas. Kitchen waste generally includes leftovers, leftovers, and vegetable leaves. 30 million tons, an astonishing amount, but the garbage disposal capacity of urban restaurants is relatively backward. If these garbage are not disposed of in time, or put in the garbage can, a large amount of carbon dioxide will be released, which will further promote t...
