Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a grain drying and preparation device.

BACKGROUND OF THE INVENTION Conventional grain drying and preparation equipment has a preparation process adjacent to a drying process.

Furthermore, Japanese Patent Publication No. 53-9977 discloses a system in which a refining silo is provided in the adjustment chamber so that the adjustment chamber is not directly affected by outside air.

In addition, a structure in which the wind tunnel of a grain storage tank with a swept floor was connected to the air path of the blower was developed in the actual development period.
It has been proposed as Publication No. 52-23969.

Problems to be Solved by the Invention However, in conventional grain drying and preparation equipment, the drying process, which generates a lot of dust, and the preparation process, which prepares fine grains, are adjacent to each other, creating a very poor working environment and reducing work efficiency. However, since the storage tank was in direct contact with the outside air, when grains such as paddy heated by drying were stored in the storage tank, the temperature difference between the outside air and the grain caused dew to condense on the inner wall of the storage tank. ,
There was a risk that the grain in the storage tank would rot or deteriorate.

In addition, the system described in Japanese Patent Publication No. 53-9977 starts the air conditioner and humidifier installed outside the control room, adjusts the temperature and humidity inside the control room, and installs a suction pipe suspended from the ceiling of the control room. The motor fan in the cylinder is operated, and the air in the lower part of the adjustment chamber is sucked in through the intake cylinder and discharged from the ceiling, and the air inside the adjustment chamber is discharged to the outside of the adjustment chamber through the intake cylinder as needed. It was hot.

Furthermore, the one described in Utility Model Application Publication No. 52-23969 is
The air blower blows air through the air passage into the wind tunnel at the bottom of the grain storage tank, and the grain in the grain storage tank is discharged to the conveyor by the wind passing through the sweep floor, and the grain storage tank is directly exposed to outside air. There was a risk that condensation would occur on the inner wall surface of the grain storage tank, causing the grains in the grain storage tank to rot or deteriorate.

It is an object of the present invention to address the above-mentioned problems and to
The drying equipment that generates a lot of dust and the preparation equipment that prepares refined products are separated from each other and are not adjacent to each other, so that the dust generated in the drying equipment does not reach the preparation equipment, which improves the working environment and improves work efficiency. Air can be circulated in the space to prevent condensation using a blower, and the storage tank is not directly affected by outside air, preventing dew from forming on the inner wall of the storage tank, and preventing spoilage, deterioration, etc. of the grain inside the storage tank. An object of the present invention is to provide a grain drying preparation device that can prevent the above problems.

Means for Solving the Problems In the grain drying and preparation apparatus of the present invention, a grain drying apparatus and a grain preparation apparatus are respectively disposed via a storage tank, the outside of the storage tank is surrounded by an outer wall via a space, and the The storage tank has a configuration characterized in that a circulating air path is formed by communicating a space with the storage tank, and a blower for blowing air into the storage tank is provided in the space.

Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In FIG. 1, 5 is a storage tank, and a grain receiving and drying device consisting of a loading hopper 2 and a dryer 3 is arranged in series with a rice preparation and milling device 6 via the storage tank 5. A tempering tank 4 is disposed between the dryer 3 and the storage tank 5, and an outer wall of the building 1 is provided outside the tempering tank 4 and the storage tank 5 with a space 7 in between, surrounding the storage tank 5. A take-out belt conveyor 9 is provided in the center of the storage tank 5 to convey the grain in the storage tank 5 to the preparation/milling device 6 from the tempering tank 4 to the preparation/milling device 6. 9
It is divided by.

As shown in FIG. 2, a perforated plate is provided at the lower part of the storage tank 5 disposed inside the building 1 via the space 7, and an air passage communicating with the space 7 is formed at the lower part of the perforated plate. At the same time, the space 7 of the storage tank 5
An opening opening to the take-out belt conveyor 9 is formed in the side wall opposite to the opening, and the space 7 and the storage tank 5 are communicated with each other to form a circulation air passage. A blower 8 for blowing air into the storage tank 5 is provided at a position, and the space 7 and the air passage under the perforated plate of the storage tank 5 are communicated via the blower 8.

Next, the operation of this embodiment will be explained.

The grains put in the putting hopper 2 are first sent to the dryer 3, and after the drying process by the dryer 3 is completed, they are put into the tempering tank 4, and then the grains in the tempering tank 4 are stored. It is placed in tank 5.

Next, when the blower 8 installed in the space 7 outside the storage tank 5 is operated at an appropriate time, the blower 8 circulates the air in the space 7 and at the same time blows air into the storage tank 5. passes through the storage tank 5, takes out the grains in the storage tank 5, and discharges them to the belt conveyor 9, and the takeout belt conveyor 9 conveys the grains to the rice preparation/milling device 6.

Effects of the Invention As described above, according to the grain drying and preparation device of the present invention, the grain drying device and the grain preparation device are arranged through storage tanks, so that the grain drying device and the grain preparation device, which generate a lot of dust, can be separated from the grain drying device and the grain preparation device, which generate a lot of dust. Since the preparation device is not adjacent to the drying device but is separated from the preparation device, dust generated in the drying device does not reach the preparation device, which improves the working environment and improves work efficiency.

In addition, the outside of the storage tank is surrounded by an outer wall through a space, the space and the storage tank are communicated to form a circulation air path, and a blower is installed in the space to blow air into the storage tank. Air can be circulated in the space to prevent condensation, and the storage tank is not directly affected by outside air, so there is no condensation on the inner wall of the storage tank, which prevents spoilage, deterioration, etc. of the grain inside the storage tank. It can be prevented.
