Petfood Drying Ovens


Klein Karoo International Ltd wanted to overhaul their control panels on two of their ovens which were used to control the humidity as well as the temperature in the drying process of pet food. Many of the old existing equipment were reused in conjunction with the new PLC and field devices.

A PLC & HMI combination enables the user to change the temperature, humidity and dry time duration set points. All variables (6x temperatue & 6x humidity) are logged into a data logger which then prints the data on-screen as well as on a USB printer. The printing frequency is batch orientated and can also be exported to a USB memory stick.
