Popis:	Mashing is a process of converting the grain starch into fermentable sugar by activating the malt enzymes using a hot-water steeping process. A microcontroller-based nine-profile, nine-segment temperature programmer and four-channel temperature and rpm (rotations per minute) display system for the mashing apparatus has been designed and implemented using a PIC 16F887 microcontroller. In this apparatus, a pulse width modulation (PWM)-based programmable AC voltage controller has been designed to vary mash tub temperature at required rate, and the resistance temperature detector (RTD) PT100 has been used to measure the temperature of the mash tub and sample. The software for the microcontroller has been developed using C language to set the end temperature and time of the nine segments of nine temperature profiles through the keypad and also to implement the proportional integral and derivative (PID) controller to control the temperature of the mash tub as per user settings.
