A heating furnace (1) is provided with: a furnace-interior space (30) for heating an object to be heated (100); an inner wall surface (40) describing the furnace-interior space, and having a first inner wall surface (41) and a second inner wall surface (42) facing one another on either side of the object to be heated (100) in the furnace-interior space (30); and heating devices (20) for heating the object to be heated (100) using a heat-radiating surface (21) for radiating heat, the heating devices being arranged on the first inner wall surface (41) and the second inner wall surface (42). The first inner wall surface (41) has a first slanted part (41a) on an upstream side in the direction of transfer (T) of the object to be heated (100), and a second slanted part (41b) on a downstream side in the transfer direction (T). The second inner wall surface (42) has a third slanted part (42a) on the upstream side in the transfer direction (T) and a fourth slanted part (42b) on the downstream side in the transfer direction (T). The heating devices (20) are arranged at a slant so that the heat-radiating surface (21) faces the center of the furnace-interior space (30). As a result, the temperature of the furnace-interior space is distributed more evenly, and a highly-energy-efficient heating furnace is provided.

Provided is a belt-driving roller that can be manufactured at low cost for driving a wire mesh belt used as a conveyor belt in a circulating manner, and also provided is a food manufacturing apparatus using the driving roller. A belt-driving roller comprises: a rotation shaft; and toothed rollers concentrically attached to the outer circumference of the rotation shaft. The toothed roller comprises: a cylindrical base part on the outer circumference of which teeth are provided in a plurality of rows to engage with a wire mesh belt; and an attachment means for attaching the base part to the rotation shaft. The belt-driving roller is used in a food manufacturing apparatus.
Apparatus manufactures thin confectionery products with uniform shapes and has first and second drying apparatuses between shape cutting and baking apparatuses for adjusting water content of raw dough pieces. The first drying apparatus has upper and lower levels, the upper level having conveyor belts at plural stages for transporting the dough pieces under hot air atmosphere and the lower level having conveyor belt for cooling, and conveyor belt for maturing the cooled pieces. The second drying apparatus has atmosphere at lower temperature than the first drying apparatus and plural rotary drums each having an inlet and an outlet and being rotatably mounted in the second apparatus. A chute transports the raw dough pieces from uppermost to lowermost ones of the rotary drums.
Provided is a driving roller that can be manufactured at low cost for circulating a wire mesh belt used as a conveyor belt, and also provided is a food manufacturing apparatus using the driving roller. A driving roller (1) comprises: a rotation shaft (2); and a toothed roller (3) concentrically attached to the outer circumference of the rotation shaft (2). The toothed roller (3) comprises: a cylindrical base part (3f) on the outer circumference of which teeth parts (3g) are provided in a plurality of rows to engage with a wire mesh belt (5); and an attachment means (3d) for attaching the base part (3f) to the rotation shaft (2). The driving roller (1) is used in a food manufacturing apparatus (25).
Disclosed is a heat food preparation device, comprising a plurality of linked food preparation housings, each having a food preparation space wherein the foodstuffs to be heat food prepared are contained; a conveyor belt that passes through the plurality of food preparation housings and conveys the foodstuffs into each food preparation housing; a steam generator unit that generates steam; a steam path that guides the steam from the steam generator unit into each food preparation housing; temperature detector units that detect the temperature within the food preparation space; a memory unit; and a controller unit. The processing temperature and the processing time for heat food preparing at multiple stages are associated and stored on a per foodstuff basis, and the processing temperature is set in each of the plurality of food preparation housings by association with the plurality of food preparation housings, corresponding to the proportion of processing time at the multiple stages. In each food preparation housing, the flow quantity of the steam that flows through the steam path is adjusted such that the temperature detected by the temperature detector units conforms to the set processing temperature. In each food preparation housing, the conveyor speed of the conveyor belt is controlled such that the foodstuffs are heat food prepared in the processing time associated with the set processing temperature.
