It plays an important role in uniformly dispersing and introducing raw materials into the processing gas stream. Although the dispersion plate 7 may be perpendicular to the rotation direction as shown in FIG. 1, it is preferable to tilt it at an angle of about 85 to 45 degrees as shown in FIG. 3 because this will improve the injection of the raw material. It is. Note that the dispersion plate 7 also has the function of scooping up the raw material that has fallen to the bottom of the dispersion section 8 and redispersing it into the processing gas.

It begins. Wet okara has a significantly large contact area with hot gas, and because the particles are small, the temperature rises quickly, and the moisture on the particle surface evaporates rapidly, so re-adhesion between particles and adhesion to the dryer membrane wall does not occur. . The bean curd that has become lighter due to the inhalation of water is carried by the hot air and moves downstream inside the inner cylinder 4, and the bean curd that has fallen into the inner cylinder 4 is lifted upward by the scraping plate 5 as the heat treatment device 1 rotates. . When the lifted bean curd comes into contact with the hot gas as it falls, it is carried downstream by the flow velocity of the hot gas, and advances into the inner cylinder 3 and the outer cylinder 2 sequentially. The same process as in the inner cylinder 4 is repeated in the inner cylinder 3 and the outer cylinder 2 to dry the bean curd.

Expelled outside. The discharged dried okara is separated from the exhaust gas by collection cyclones 21 and 22, and sent to a flour mill 25 via a rotary valve 24. The okara pulverized in the milling process [25] is sieved by a product vibrating sieve 26, the bottom part of the sieve is sent to a product silo (not shown) through a conduit 27, and the part above the sieve is circulated through a conduit 28 to a drying fi 20. The gas separated by the collection cyclones 21 and 22 is sucked by a blower 23 and sent to an exhaust gas treatment device (not shown) such as a deodorization device for treatment.
