APPLICATION OF MITSUBISHI ELECTRIC EQUIPMENT FOR AUTOMATION OF THE PASTEURIZING AND COOLING UNIT
Mitsubishi Electric is a world leader in production of the compact programmable logic controllers. Industrial automation of Mitsubishi Electric first of all is noted for its quality, simplicity and reliability. Although the scopes of application of this equipment are quite diverse, in recent years their use dramatically increased in different sectors of the food industry, in particular for automation of pasteurization and cooling unit.
All modes of pasteurization and cooling unit:
- automatic flow configuration by lines;
- automatic exit the operating mode on the water;
- flow control (not allowed to mix water and milk);
- control of milk flow during pasteurization and of temperature conditions in each section of the unit;
- control of supply of the coolant and refrigerant in the unit;
- implementation of the process of push-off of the pasteurized milk;
- automatic washing
very simple and well implemented on the FX industrial controllers. High-speed processor, use of high-speed instructions and high resolution of the analog modules can improve the quality of pasteurization and eliminate the risk to get a non-pasteurized product. The schedule of pasteurization is recorded and archived on the memory card, and can be displayed and printed on the computer, or directly on GOT 2000 touch pad, eliminating the use of expensive recording instruments. The use of Mitsubishi Electric touch pads has made it possible to use them as multifunction instruments of man-machine interface, which display information about the equipment control of pasteurization unit, archiving of process data, analysis and sending of alarm messages to the addressee, both on the company local network, and to the Internet users. Due to the built-in function “remote desktop”, GOT 2000 panels make it possible to re-consider working mode of pasteurization and cooling unit and if necessary to interfere in the process from any PC, at the same time eliminating expenses for purchase of scadа-system. Use of a single protocol of serial communication between the products of Mitsubishi Electric ensures perfect integration and data communication between FX controllers and FR frequency transducers, ensuring reduction of the operating expenses for pumping equipment, even feed of product into the pasteurization and cooling unit and energy saving.
