AI Technical Summary

Technical Problem

Existing fermentation devices for Chinese medicinal herb residues have dead zones in the mixing process, resulting in slow fermentation speeds, and lack biogas collection and treatment devices, which pollute the environment.

Method used

A fermentation device for Chinese herbal medicine residues was designed, which includes a fermentation tank, a stirring mechanism, and an exhaust mechanism. The fermentation efficiency is improved by using a stirring paddle and scraper assembly driven by a servo motor, and biogas is collected through the exhaust mechanism to avoid pollution.

Benefits of technology

It improves the fermentation rate, reduces the adhesion of Chinese herbal medicine residue, enhances fermentation efficiency, and effectively collects and treats biogas, preventing environmental pollution.

Abstract

This utility model discloses a fermentation device for traditional Chinese medicine residue, relating to the field of traditional Chinese medicine technology. It includes a fermentation mechanism with an internal stirring mechanism and a venting mechanism on its side. By using a venting mechanism composed of a connecting block, connecting pipe, vent valve, air pump, vent pipe, and gas collection tank, this utility model can collect biogas generated from the traditional Chinese medicine residue inside the device, avoiding environmental pollution. When needed, simply open the vent valve and start the air pump. The air pump draws the biogas generated inside the device through the connecting pipe and then through the vent pipe into the gas collection tank for collection.
