Automated Testing for Quality Inspection of Food Grains

Abstract

The visual inspection and odor check of food grains was the at most need of the farmer to inspect the quality of the food grains in order to prevent them from deterioration. Sensor measurements will provide need of efficient and faster method to inspect the quality of the grains. This process is an attempt toward developing an automated testing setup for quality inspection of food grains. Frame works for conveyer belt were designed such that it will be able to withstand the loads acting on it. Suitable belt thickness is calculated for belt system and is fabricated, which is connected to motors to facilitate the movement of food grain containers on it. Sensors for measurements of odor, temperature and humidity were attached at the appropriate position, and a microcontroller is programmed in order to control the entire system. An arm is actuated to push the spoilt grain sample so as to reject the sample.KeywordsAutomated quality inspectionSensor measurementFood grainsVisual inspection
