Kitchen waste fermentation apparatus air supply system and kitchen waste fermentation apparatus

Abstract

The invention provides a kitchen waste fermentation apparatus air supply system and a kitchen waste fermentation apparatus. The air supply system comprises intake units; each intake unit includes an intake tube and an overflow tube, one end of the intake tube is connected to a sidewall of the overflow tube and is communicated with the overflow tube, two ends of the overflow tube are closed, the overflow tube is provided with a plurality of air outlets, the multiple air outlets are spaced axially along the overflow tube, spacing of every two adjacent air outlets increases gradually from the lengthwise middle of the overflow tube to its two ends. The kitchen waste fermentation apparatus comprises the air supply system. The air supply system is simple and reasonable, is easy to manufacture and process and is low in manufacturing and mounting cost; the air supply system can provide sufficient air into a fermentation barrel, the temperature in the fermentation barrel can be satisfied, a good environment is provided for the fermentation of material in the fermentation barrel, fermentation quality and speed of the material are increased, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of garbage composting, in particular to a food waste fermentation equipment gas supply system and kitchen waste fermentation equipment. Background technique [0002] At present, the air supply methods of food waste composting fermentation equipment mainly include dynamic reverse air supply, that is, when the main fermentation equipment is in the dynamic state of rotation, through the design of the air path of the reverse air supply system and the control of wind speed, blowing air from the tail to the dynamic Oxygen is supplied to the raw material, waste gas is discharged, and the heat energy of the high-temperature material and the excess heat energy released during the fermentation stage are passed through the airflow to realize heat transfer and exchange, heat up and moisten the new material in the stage of inoculation waiting for the temperature rise, and promote the proliferation and reproduction of micr...

AI Technical Summary

Problems solved by technology

The existing air supply system blows air from the tail to the front of the main fermentation equipment in a dynamic state. When the air flow passes through the decomposing stage, although a large number of microorganisms have died or dormant, they basically do not consume oxygen. Oxygen at a higher temperature is absorbed by microorganisms, but because the process time is too short, the time for microorganisms to absorb oxygen is not enough, and there is not enough oxygen for microorganisms to reproduce in large numbers, which affects the speed of biochemical reactions

If the oxygen supply time is prolonged, the temperature will be greatly reduced due to the large amount of heat lost with the exhaust gas. It is difficult to control the temperature that needs to be continuously maintained during the main fermentation process, and it is difficult to ensure product quality.
