In addition, the fluid is characterized in that the steam, water or thermal oil. In addition, the pipe is installed in a plurality at a predetermined interval in the horizontal and vertical directions;

The present invention relates to a hopper type drying apparatus devised to solve the above problems, and more particularly, a heat source for supplying high temperature heat and a heat transfer material formed around and inside the main body to receive and heat heat from the heat source. By increasing the heat transfer area and residence time it can maximize the drying efficiency.

Hereinafter, the configuration and structure of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a hopper type drying apparatus 1 according to the present invention, a main body 10 having a space formed therein for accommodating the dried matter, and an inlet opening at the upper portion for drying the dried matter. 11) is formed.

2 is an exemplary view showing a pipe 22 and a jacket 21 installed in the hopper type drying apparatus 1 according to the present invention.

As shown, a jacket 21 is formed to surround the body, and the jacket is filled with a fluid supplied from a heat source to heat the inside of the body by circulating the jacket.

In addition, a plurality of pipes 22 at regular intervals are installed in the main body in a horizontal and vertical direction, and the pipes 22 communicate with a jacket 21 surrounding the main body, and a single inside of the main body The jacket 21 may be further installed and the fluid may be circulated in the inside of the jacket 21 to be installed further, and may be in communication with the pipe 22 to increase the heat transfer area, thereby transferring heat more effectively.

The drying apparatus 1 is provided with at least one fluid supply port 23 and the fluid discharge port 24 for supplying and discharging the rapeseed and the fluid supplied to the fluid supply port 23 is the jacket 21 After circulation, the discharged through the fluid outlet 24 and the discharged fluid is repeated so that the circulation to be re-introduced into the fluid supply (23).

Hot water, steam or heat medium oil is used as the supplied fluid, and heat medium oil has an advantage of obtaining high temperature heat with an available temperature of -10 to 15 ° C to 250 to 300 ° C. The boiler may use steam, hot water, fruit oil, and the pipe 22 may use a heat pipe having high thermal conductivity.

The upper portion of the jacket 21 installed inside the main body is separated into a left or right accommodating space, and the upper portion of the jacket 21 installed in the main body is formed in a cross section of a V-shaped or V-shaped.

The dry matter introduced through the inlet 11 is in contact with the plurality of pipes 22 installed in the horizontal and vertical directions during the fall, so that the residence time increases, and the dried material is dried through the body inner wall and the pipe heated through the fluid. It will have a structure that makes it possible.

In addition, at least one air supply port 41 is provided at the lower end of the main body while staying in the accommodation space and supplies air from the air source 42 to remove residual moisture of the dry matter. The air supplied from the air supply port 41 moves upward along the inner wall of the main body to remove moisture from the dried product.

In addition, the moist air moved to the upper portion of the body to remove the moisture of the dry to be discharged to the outside by using a fan 44 installed on the outside.

The dry matter staying by the pipe 22 and being heated by the fluid and the pipe, and dried by the supplied air falls to the transfer screw 31 in the lower part of the main body, and the dry matter which is sequentially accumulated is powered from the central motor 43. By the transfer of the transfer screw 31 that is received and rotated is transferred to the recycle conveyor 32 through the first outlet (12).

The recycle conveyor 32 serves to transfer the dry matter to the inlet 11 of the upper portion of the main body and to re-inject it. In addition, the drying is transported to the inlet 11 has the effect that the residual moisture is evaporated by exposure to the atmosphere.

The cycle from the first drying process to the re-injection process through the recycle conveyor 32 is repeated to dry the dried product by changing the rotation of the transfer screw 31 in the opposite direction to the initial rotation direction and then the second discharge port ( 13) to be discharged to the outside.

In addition, when the dry matter is added through the cycle, the water content of the dry matter decreases, so that the volume of the firstly added dry matter may be further added to the new dry matter.

5 to 6 is a reference view of an example of the use of the hopper type drying apparatus 1 according to the present invention, wherein the first dried product stays in the pipe 22 installed on the inner wall of the main body and is heated and supplied by the high heat fluid. The water is evaporated and falls in the downward direction, and is shown in the circulation state up to the process of being transported to the recycle conveyor 32 through the first outlet 12 by the transfer screw 31 and re-introduced into the main body.

In addition, when the product is discharged in the completely dried state after the process by repeating the dry matter, if the rotation direction of the transfer screw 31 is changed in the opposite direction to the initial rotation direction, the dried product is completely dried through the second outlet 13. It can be discharged.
