WOOD MATERIAL BOARD HOT-PRESSING DEVICE AND OPERATION PROCESS FOR SUCH A DEVICE Russian patent published in 2018 - IPC B27N3/20 

FIELD: woodworking industry.

SUBSTANCE: invention relates to the woodworking industry, in particular to devices for hot pressing wood chipboards. Installation contains a primary circuit, a secondary circuit and an adjusting device. Unit is equipped with a secondary circulation pump with variable capacity, which is located for circulation of the heat medium fluid in the secondary circuit. Adjusting device has a device for recording the heating power, which is provided with a supply thermometer for measuring the temperature of the supply of the heating medium, which flows in the secondary circuit to the pressing device and a return thermometer to measure the return temperature of the heat medium that flows in the secondary circuit back from the press device. Adjusting device is designed to automatically control the heating power that is supplied to the pressing device based on the flow of the heat medium fluid through the secondary circuit and the temperature difference between the supply temperature and the return temperature in the secondary circuit.

EFFECT: productivity of the hot pressing plant is increased.
