METHOD OF AUTOMATIC CONTROL OVER PRODUCTION OF BIOFUEL FROM WOODEN LOOSE STOCK Russian patent published in 2009 - IPC C10L5/44 

FIELD: process engineering.

SUBSTANCE: proposed method relates to processing of loose wastes formed in wood processing and can be used for producing ecologically pure buofuels for industrial and communal services. Proposed method comprises grinding the material, processing it by superheated steam at 300°C in filtration conditions, and subsequent pressing. Proposed method comprises measuring the finished product temperature and moisture content at the press unit outlet, comparing measurement results with rated magnitudes preset at microcontroller. Control signals from the latter are sent to actuating mechanisms to vary the rate of material feed in press die temperature control circuit, and to actuating mechanism that allows feeding superheated steam into the mixer included into moisture content control circuit.

EFFECT: reduced inflammability, optimum moisture content of finished products.
