Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a coin rice mill that operates by inserting coins.
[0002]
[Prior art]
A conventional coin mill is installed in a relatively small building and is open 24 hours a day throughout the year. However, it is set to keep a standby state unless a user inserts a coin. Conventionally, a building in which a coin rice mill is installed is generally a simple prefabricated house, and therefore, particularly in winter, the room is cooled down to the extent that it does not change outdoors. Therefore, if the waiting time is long, the equipment mainly made of steel plate material will be completely cooled, but even in such an environment, the conventional coin milling machine is short-term by inserting coins. Rice milling can be done without any problem.
[0003]
[Problems to be solved by the invention]
However, when brown rice is put into a chilled rice milling machine, rice milling is performed, and the temperature of the white rice that has risen due to friction caused by the milling action results in rapid heating centering on the equipment through which the white rice passes, resulting in condensation. . In particular, in the annexed been rice pumped device downstream of rice device in consideration of the work of the time of recovery of rice, bucket with a flat belt that pumped the rice whose temperature has increased, chilled Since it is contained in an outer case made of a steel plate material, the heat generated by the white rice is trapped inside the case, and the occurrence of dew condensation becomes prominent.
[0004]
Condensation generated on the surface of the device promotes the adhesion of floating soot to the surface, and eventually accumulates thickly by repeating condensation and adhesion each time it is used. The thickly accumulated rice cake absorbs moisture at the time of dew condensation and inhibits the drying of the device, causing problems such as rusting of the device and mixing of mold generated in the accumulated rice cake into white rice. Although such condensation can be prevented by keeping the room temperature in the machine room at about 15 ° C. or higher, unmanned operation of the heating device for 24 hours has a problem in terms of disaster prevention. There is also a problem that the usage fee is not profitable.
[0005]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coin rice mill that can prevent condensation that occurs in winter in equipment that mainly passes white rice.
