小型智能餐厨垃圾处理设备温控系统的设计

Design of Temperature Control System for Small Intelligent Food Waste Treatment Equipment

基于我国餐厨垃圾高油、高盐、高含水率、有机物含量高和营养物质丰富的特点,设计一种小型智能餐厨垃圾处理设备。其利用复合微生物菌群分别适应好氧、厌氧、兼氧型微生物在不同时段的活力和发酵优势产生有机肥。研究发现,合适的温度可提升餐厨垃圾的处理效率和减少氮素损失。重点讲述了温度控制模块,用Arduino Mega 2560单片机作为控制板,温度控制模块主要包括加热装置、鼓风机和温度测量装置等。将采集的温度数据传送至模糊PID控制器,经试验验证温度控制误差小于1%,可以满足复合微生物菌群发酵对温度的需求。

Based on the characteristics of food waste in China,such as high oil,high salt,high water content,high organic content and rich nutrients,a small intelligent food waste treatment equipment has been designed to produce organic fertilizer by adapting the vitality and fermentation advantages of aerobic,anaerobic and facultative micro organisms in different periods with compound microbial flora.It is found that proper temperature can promote the treatment efficiency of food waste and reduce nitrogen loss.This paper focuses on the temperature control module.The Arduino Mega 2560 single chip microcomputer is used as the control board.The temperature control module mainly includes the heating device,blower and temperature measurement.The collected temperature data is sent to the fuzzy PID controller,and the test results show that the temperature control error is less than 1%,which can meet the temperature requirements of compound microbial fermentation.
