AI Technical Summary

Technical Problem

Existing smoke treatment equipment generated during coffee roasting has problems such as insufficient mixing of airflow and flame, uneven smoke removal, high energy consumption, excessively high equipment surface temperature, and fire hazards. Furthermore, the independent operation of the smoke remover and the roaster leads to energy waste.

Method used

Design a safe and energy-saving smoke removal machine, including a preheating layer and a combustion chamber. The flue gas is preheated by rotation in the preheating layer and then enters the combustion chamber to mix fully with the flame. The air curtain formed by the interlayer reduces the temperature of the equipment, and intelligent control is achieved through temperature sensors and a control system to avoid unnecessary energy consumption.

Benefits of technology

It achieves uniform mixing of flue gas and flame, reduces energy consumption, improves smoke removal effect, reduces equipment temperature and fire risk, and realizes energy-saving and intelligent operation of the equipment.
