Abstract

PROBLEM TO BE SOLVED: To efficiently reduce a moisture content contained in OKARA (bean- curd refuse) by a simple equipment by pressing okara uniformly into a thin plate-form to the surface of a cylindrical lateral roller, which rotates while heating, by a pressing roller, and drying the OKARA. SOLUTION: Saturated steam, which is heated and pressurized, is placed from a steam inlet into a cylindrical lateral roller 3, which rotates at a low speed. Then, the saturated steam is taken out from a steam outlet in a manner to be circulated, and thus, OKARA is heated. On the cylindrical lateral roller 3, a pressing roller 2 is arranged, and a pressurizing device such as a pressurizing cylinder is provided. Thus, a structure wherein the OKARA 17 is pressed by the cylindrical lateral roller 3 is formed. Then, the OKARA of a non-specified amount, which is charged as a lump from a feeding hopper 1, is continuously pressed by the cylindrical lateral roller 3 into a thin plate-form by a specified amount regardless of the charged amount, and the OKARA 17 is heat-dried. By this constitution, a lump charging can be performed. In addition, a moisture content contained in the OKARA can be efficiently reduced by a small and inexpensive device.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for heating and drying okara with a high water content.

[0002]

2. Description of the Related Art Conventionally, the water content of a large amount of okara processed by a dehydrator or a pressing machine is as large as 70 to 75%. A rotary kiln, a screw feed type drying device (Japanese Patent Laid-Open No. 10-165126) and the like are known.

[0003]

When okara is treated as feed or waste, it contains a large amount of water, so it emits an unpleasant odor in 4 to 5 hours in the summer, and its volume is large, which is a problem in weight. I have.

In a conventional drying apparatus such as a rotary kiln, since it is a continuous supply type, it cannot be charged all at once, so many accessories are required, and the apparatus itself becomes longer due to heat transfer time. The fact is that it is difficult for small-scale companies to adopt such a system because a dust collector for processing is required and a compression device is required after processing.

An object of the present invention is to solve the problems of the conventional apparatus and to provide a roller-type heat-drying processing apparatus capable of reducing long-term storage and transportation costs when used for feed and disposal by simple equipment. .

[0006]

According to the present invention, an okara roller heating and drying apparatus according to the present invention comprises a heated cylindrical horizontal roller 3 and a heating roller disposed on the cylindrical horizontal roller 3 as shown in FIG. A supply hopper 1 for batch-feeding the pressure roller 2 and okara, a knife 4 for scraping the dried okara, a suction fan 7 for sucking the evaporated water vapor, and a hood 6 for covering the cylindrical horizontal roller 3 It is characterized by.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. There is a cylindrical horizontal roller 3 that rotates at a low speed from a motor 8 with a reduction gear via a motor pulley 10, a belt 11 and a pulley 9. Saturated steam heated and pressurized from a steam inlet 14 is introduced into the cylindrical horizontal roller 3, and saturated steam is taken out from a steam outlet 15 and circulated.
By pressurizing the saturated steam to 9 weight kilograms per square centimeter, the surface temperature of the cylindrical roller 3 can be maintained at about 180 ° C. As a heating means of the cylindrical horizontal roller 3, an electric heater such as a heater for heating may be used.

The pressure roller 2 is placed on the cylindrical horizontal roller 3.
The pressure cylinder 12 or the pressure spring 13
And so on, so that the okara 17 is pressed against the cylindrical horizontal roller 3. By providing a stopper with adjustment or the like on the bearing of the pressure roller 2, it can be stopped at any gap. The unspecified amount of okara that has been batch-fed from the supply hopper 1 is continuously pressed by the pressing roller 2 into a thin plate shape and is heated and dried without being affected by the feeding amount. .

When crimping okara, the cylindrical horizontal roller 3
In order to prevent the okara from being peeled off, a surface treatment is performed by plating or coating with ceramics or the like, and the pressure roller 2 is made of rubber, resin, or the like so that the okara can be pressed evenly without being attached. Perform surface treatment.

By covering the outer periphery of the cylindrical horizontal roller 3 with the hood 6, heat can be prevented from dissipating and a heat retaining property can be provided. The steam evaporated from the okara may be exhausted using an exhaust device such as a chimney or a duct, but can be efficiently exhausted by sucking it with the suction fan 7. The gap between the cylindrical horizontal roller 3 and the packing 6 attached to the hood 6 is adjusted, the hood 6 is made airtight, and the suction is performed by the suction fan 7. (Boiling point of about 80 ° C. at a pressure of −380 mmHg) to promote evaporation, and okara can be dried more efficiently.

The dried okara is scraped to the discharge hopper 5 by a scraping knife 4 made of a copper alloy, FRP or the like so as not to damage the surface of the cylindrical horizontal roller 3.

[0012]

According to the present invention, since the apparatus can be batch-injected, and is small and inexpensive, it is suitable for a small company. And efficiently reduce the water content of okara,
Since compression is performed in the drying process, the volume is reduced without providing a separate compression process as in the conventional technology. The weight can be reduced, and the post-treatment process can be made significant by long-term storage and effective use for feed.
