IoT Driven High Pressure Pasteurisation

Nowadays, the most common way to treat milk is pasteurisation. But there are worries that heating milk to pasteurise it could destroy enzymes, lower vitamin levels, denature sensitive milk proteins, destroy vitamin B12 and vitamin B6, kill good bacteria, and encourage the growth of pathogens. Our suggested approach seeks to provide a substitute for conventional heat treatment in the pasteurisation of milk. The fundamental idea behind this suggested remedy is the introduction of a high-pressure pasteurisation method that doesn't require traditional heat treatment. For industrial use, this fully automated system comes highly recommended. The hardware module and the software module are its two main parts.The system's hardware consists of a high-pressure chamber that pasteurised raw milk by applying intense pressure. A linear actuator applies pressure, and the pH sensor confirms the action. The pH levels are continuously changing on the LCD display. An Arduino MEGA microcontroller board is incorporated into the software module to combine the hardware and automate the entire process. By interacting with the ESP module, the start and stop of the operation can be wirelessly managed and saved in the cloud for further use. The main benefit of pressure pasteurisation over traditional heat treatment is that it avoids denaturation by maintaining the protein structure and nutritional content throughout the process.
