In addition, at a predetermined position on the upper side of the circulation pipe 160, a vacuum pump 181 is provided to maintain a vacuum state while exhausting the air inside the main body 100 by the driving motor 180.

And although not shown in detail in the lower predetermined position of the circulation pipe 160 is provided with an injection pipe for injecting inert gas and at the same time it is provided with an on-off valve 190 in the injection pipe.

Therefore, if described in detail the effect of the present invention is configured as follows.

That is, when the rice to be dried in the rotary drying furnace 150 is pressed and the operation button of the control unit is pressed, the control unit operates the driving motors and the heaters 172 of the respective driving units.

Accordingly, the power of the driving motor 140 is transmitted to the rotary drying furnace 150 through the pulley to rotate the rotary drying furnace 150, and the rotary drying furnace 150 supports the hot air spraying shaft 120. It will be rotated.

This operation will be a separation process in which the dry matter is separated from the dry matter by rotating the rotary drying furnace 150 containing the dry matter.

The separation process is performed and the evaporation process is performed. That is, the driving motor 170 and the heater 172 of the exothermic blowing means are operated to suck the air in the case member 110 by the blowing force of the blowing fan 171. Then, the air is blown to the hot air jet shaft 120 through the circulation tube 160 in the state heated by the heater 172, and the blown hot air is blown into the hot air jet shaft 120 at a plurality of blow holes. It is blown into the rotary drying furnace 150 through (121).

Therefore, the rotary drying furnace 150 rotates the hot air spraying shaft 120 as a supporting point while hot air is blown into the hot air spraying shaft 120 so that the rice grains stored in the rotary drying furnace 150 are dried according to the load. Will be.

As such, the hot air heat-exchanged with the rice in the rotary drying furnace 150 is repeatedly circulated through the circulation pipe 160 provided to communicate with the upper side of the case member 110, thereby drying and moisture will be separated.

At this time, the operation of the exothermic blower means to control the operating time and the temperature in the rotary drying furnace 150 in the control unit according to the type and characteristics of the agricultural products to be dried.

If the operation is continued and the moisture contained in the dry matter is completely evaporated to achieve a vapor saturation state of the case member 110, the evaporation process is completed, and the drying process is continued.

The drying process stops the operation of the exothermic air blowing means, that is, the driving motor 170 and the heater 172 and at the same time operates the driving motor 180 of the vacuum impregnation means.

Therefore, the vacuum pump 181 is operated by the driving force of the driving motor 180 to discharge the moisture in the vapor state diffused in the rotary drying furnace 150, that is, the case member 110 to the outside.

Accordingly, the interior of the rotary drying furnace 150 is gradually vacuumed to accelerate and increase the evaporation and diffusion of the evaporated moisture contained in the dry matter, thereby lowering the moisture content of the dry matter to the required function within a short time.

After the controlled drying time has elapsed according to the type of dry produce, the rotary drying furnace 150 is vacuumed, and the dried product is sufficiently dried to complete the drying process. Afterwards, an antiseptic process is performed to prevent corruption during distribution and storage. You lose.

Although the preservative process is not shown in the drawing, the gas will be supplied from the gas supply tank connected to the on-off valve 190 and supplied into the case member 110.

Is to be.

When the dried rice is completely discharged from the rotary drying furnace 150 as described above, the operation member 124 is moved back to the original position while the rod 123 is advanced. Accordingly, the opening and closing member 130 connected to the rod 123 is hot air sprayed. As it descends along the shaft 120 to close the cut groove 122 of the hot air jet shaft 120 will wait for the drying process of another rice grain to be dried.

Therefore, the present invention, as described above, has a very simple configuration compared to the conventional configuration, which not only has the effect of improving the manufacturability, but also keeps the drying object to be dried by providing a single unit without separating the rotary drying furnace from the main body. It will have the effect of drying continuously.

In other words, once the drying process is performed, the next drying object is stored immediately to achieve the drying process, thereby improving productivity according to the drying operation.

First of all, the drying time is shortened and at the same time complete drying is expected to have an effect of improving the drying efficiency.
