Design a VAT milk pasteurizer in Tanzania

The project presents “Design of micro-VAT milk pasteurizer” The microcontroller temperature regulator provides an automated way of controlling the temperature of a given pasteurizer for pasteurizing the milk at a given temperature (63 oC for 30 minutes). This project is realizable via temperature sensing, signal conditioning and relaying. The temperature sensor senses the current of the said pasteurizer, send it to the ADC (Analogue to Digital Converter) the digitized signal is then sent a controller which through the help of a programmed input (software), does the comparison and control by sending a feedback signal to the heating element thereby bringing about the regulation of the temperature of the said pasteurizer. A great advantage of this project is that it provides automated, and it is reliable, if there can be a constant power supply to the system. It is also economical in construction. Agricultural products such as milk in their raw state have harmful organisms such as viruses and bacterial that are known for causing diseases when consumed. For safe consumption and healthy leaving, this organism needs to be reduced or eliminated
