AI Technical Summary

Technical Problem

In the existing technology, the fermentation process of peanut bran has problems such as low efficiency, unstable quality and inconvenient operation. In particular, there is a lack of suitable portable fermentation devices in small and medium-sized and decentralized application scenarios. Moreover, the existing industrial equipment is costly and complex in structure, making it difficult to popularize.

Method used

A portable peanut bran fermentation device was designed, comprising a double-layered fermentation tank and a heat pump system, equipped with sensors and a stirring motor to achieve precise control of fermentation parameters, including temperature, pH value and dissolved oxygen concentration. An intelligent control system is used to automatically adjust the fermentation process, and integrated stirring and defoaming devices ensure uniform mixing and rapid fermentation of materials.

Benefits of technology

It achieves rapid and stable fermentation of peanut bran, completely kills harmful bacteria and parasites, shortens the fermentation cycle to 36 hours, and produces high-quality bio-organic fertilizer without waste gas, wastewater, or waste discharge, thus reducing production costs and labor intensity.
