Automation of a Pumpkin Seeds’ Drying Process

In this article an automation of a pumpkin seeds’ drying machine is examined in two different configuration solutions. The first configuration uses relay devices and requires more interaction with the machine to achieve a successful process. The second configuration utilizes a more complex configuration with programmable logic controller (PLC) to increase the automation level in the process, thus reducing the need for operator intervention. For both versions, a wiring project was designed, and component costs were calculated. Additionally, for the version with the PLC, accompanying code was also developed and tested.
