The oven is used in the food industry, in trade and for drying of bulk materials. Its design is simple and reliable, and is fired on timber wastes. It consists of a frame (1) with rollers (3, 15), fitted under a belt (4), the ends of which are fitted in cross pieces connected by a chain (8) going round a sprocket (9). This guiding module includes a motor reduction gear (13) and is connected to a guided belt-and-chain modules by means of gear (10, 11) and intermediate (12) wheels. The intermediate wheel is meshed to a large gear wheel (18) of a belt-and-chain hopper (22) in the form of a square-shaped flow of screened timber and wood wastes (23) pressed to drum (5) by means of a screen of chains (24). To the fireplace (25) there is a sheet steel tray with rammed wooden wastes (23), and a conical smoke flue (30) is inserted over the gas bleeder (29) which is coaxially engaged by a conical heat-exchanger (32). 6 claims, 7 figures
