A biodegradable garbage disposer and its method for producing bacterial protein

Abstract

The invention discloses a biodegradable garbage processor, which is characterized in that the garbage processor is composed of four parts: a garbage crushing system, a garbage fermentation system, a garbage waste gas and liquid treatment system and a ventilation system. Simultaneously, the invention also discloses a method for producing bacterial protein from biodegradable garbage, step 1: raw material crushing; step 2: fermentation and separation; step 3: strain circulation; step 4: culturing and collecting. Using the garbage disposer, the bacterial protein obtained after processing the biodegradable part of kitchen waste and urban garbage can reach more than 30%, which can be used as a feed additive. At the same time, the processor is also equipped with a flower and plant cultivation room, which not only handles the waste gas generated during the fermentation process, but also contributes to the improvement of environmental quality. The production process of the device is simple, easy to use, and truly realizes resource utilization, reduction and benefit of waste disposal.

Description

technical field [0001] The invention relates to the fields of environmental protection technology and biotechnology, in particular to a biodegradable garbage processor and a method for producing bacterial protein. Background technique [0002] The main characteristics of kitchen waste are rich in organic matter, high in water content, and perishable. Its properties and odor will have a bad impact on environmental sanitation, and it is easy to breed harmful substances such as pathogenic microorganisms and mycotoxins. What was good food one minute ago is trash the next minute. Due to the food culture and eating habits, kitchen waste has become a unique phenomenon in China. The table waste in China is astonishing, and a huge amount of kitchen waste is produced every day. According to figures from the Beijing Municipal Development and Reform Commission, Beijing produces 1,200 tons of food waste every day. Statistics from the Institute of Solid Waste Pollution Control and Recy...

AI Technical Summary

Problems solved by technology

[0012] 1. High energy consumption is a burden for ordinary families, affordable but unaffordable

[0013] 2. The traditional food waste disposer is generally placed in the kitchen. The shell is made of single-layer ABS plastic, supplemented by iron sheet and steel sheet to decorate the shape. The existence of iron sheet and steel sheet also causes the hidden danger of non-insulator conductive electric shock

[0014] 3. The traditional food waste disposer is simple and rough, and the waste is not sufficiently ground, and the grinding particles are too large, which often leads to blockage of the drain pipe and substandard water discharge from the sewage treatment plant.

[0015] 4. The old garbage processors use ordinary DC motors, which require maintenance tracking, low starting torque, and short service life

[0016] 5. Most garbage disposers have small calibers, are not easy to feed, slow grinding speed, cumbersome operation, unsafe, etc.

And it needs the cooperation of the faucet, which is cumbersome to use

[0017] 6. Most garbage processor grinding chambers are made of plastic material, which is easy to deform, easy to seep water, easy to burn out the switch or motor, and has a short service life

[0018] 7. The old domestic waste disposer can only be fixed in the kitchen and cannot be moved
