Desarrollo de un sistemas automático con control difuso para el batido de gelatina en la fabricación de dulces artesanales

Abstract

In the proposed system, the fuzzy logic for the speed control of the motor that makes the shake in the manufacture of artisan sweets (gummies) was implemented. The implementation of the fuzzy controller provides an optimal speed to the engine depending on the level and temperature of the gelatin, in order to automate the process to reduce raw material waste and improve the volume of production of the micro company "Anly". The level of the gelatin in the container and the temperature thereof were taken as input variables of the fuzzy controller, while, as an output, it was taken at the frequency of the inverter, which has a relationship directly proportional to the speed of the motor shaft. The brain of the fuzzy controller is an "Arduino Nano", a small and complete development board based on the "ATmega328P" microcontroller. The sensors that provide information on the conditions of the gelatin according to the magnitude to be measured are: An ultrasonic sensor to know the level of growth of the same inside the container and a thermocouple type K connected to the amplifier "MAX6675" to know the temperature of the substance. The output of the fuzzy controller delivered by "Arduino" was coupled to a frequency inverter "SV008iG5-2" through a hardware designed that gives a variation of voltage according to the analog control input of the inverter. A comparison of the production before and after the automation showed a waste reduction index of 97.5%, the process time was reduced in 27 seconds and the volume of whipped gelatin was increased by 1.35 L. The results obtained by the machine were satisfactory for the micro company.
