1/-"75 IT DONOI C, I1 (This technology and its application technology have been proposed. That is, conventionally, drying of materials to be dried in a hollow chamber generally requires a heat source and a blower that blows the heated air. Therefore, the present inventor has developed a drying apparatus and drying method consisting of a hollow chamber having a decompression equilibrium friction heat generation mechanism that does not require a special heat source. However, this invention provides a granule in which a vacuum equilibrium heating device for granules is installed inside the hollow body, which can more effectively exert heat generation effect and drying effect when the above-mentioned invention is used for drying granular materials such as grains and fruits. The object of the present invention is to provide a multi-stage reduced pressure equilibrium heating device for use in the present invention.

10), an outside air introduction pipe (11), and a valve (12l).

That is, the hollow chamber (2) is formed in a sealed state except for the necessary ventilation cylinder, and the reduced pressure equilibrium friction heat generation mechanism (2) is installed in the upper part. In this embodiment, the reduced pressure equilibrium frictional heat generation mechanism (2) includes a rotating body (4) having rotating blades and a rotating body (4).
It consists of a substantially cylindrical intake cylinder {5} with a Rotating body 4
Reference numeral 1 denotes an electric motor (6) which can rotate in the direction of suctioning and exhausting the gas in the hollow chamber (2). A frictional heat generating portion A is formed in the rotating region of the rotating body (4).

The cylindrical chamber (7) is continuous with the upper part of the depressurized equilibrium frictional heat generation mechanism (2), and a heating plate (8) made of metal such as aluminum made of a flat plate or a corrugated plate is protruded on the outer periphery of the cylindrical chamber (7). Set up In this embodiment, the number of heating plates is four, but the number can be freely selected as required, and the shape of the heating plate (8) can also be freely selected. Although the upper part of the cylindrical chamber (7) is directly connected to the outside of the apparatus in this embodiment, a damper may be provided for adjusting the amount of gas flowing out. The granule storage chamber (9) is
A reduced pressure equilibrium friction heat generation mechanism (9), a hollow chamber (6), a heating plate (7), an electric motor (5), etc. are installed inside, and a hollow chamber {2} is formed at the bottom.
Formed to allow ventilation. The granule storage chamber (9) is formed in a sealed state except for the ventilation section (111) with the hollow chamber 12),
Further, a dry smoked material storage opening (not shown) is formed in the upper part, which can be opened and closed freely. The outside air introduction pipe (11) is capable of supplying gas into the hollow chamber (2) according to the required amount via the valve (12). Further, if necessary, the gas introduced into the hollow chamber may be preheated by the outside air introduction pipe (11). (13) is a crushed dried product, which is grain such as rice and wheat, fruits, and other granules, and is filled into the granule storage chamber. (14) is a hollow body having a closed shape, and houses the granule vacuum equilibrium heating device (1) therein. In this embodiment, the hollow body (14) consists of one unit, but the hollow body (14) has one other smaller hollow body inside it.
Alternatively, it may be a multiplex structure in which two or more are sequentially installed. When the hollow body (14) has another hollow body installed therein, the granule vacuum equilibrium heating device is installed in the innermost hollow body. In this embodiment, the hollow body 114i has a reduced pressure equilibrium frictional heat generating mechanism (3)' in the upper part. Although the hollow body 114i does not need to have this mechanism, it is desirable for the drying effect to have this mechanism. In this embodiment, the equilibrium frictional heat generating mechanism (3)' installed in the hollow body +14i is a rotating body C4}' and a rotating body {
Consisting of a substantially cylindrical intake pipe (5)' with a
The rotating body 141' can be rotated by an electric motor (6)' in the direction of suctioning and exhausting the gas inside the hollow body.

The operation of the vacuum equilibrium friction heat generation mechanism 131' of the hollow body I and the vacuum equilibrium friction heat generator groove 13 of the granule material vacuum equilibrium device (1) may be controlled by a control device' (. (not shown). A friction heat generating portion (A') is formed in the rotating region of the rotating body {〆11'.]' is an outside air introduction pipe;
It is possible to supply outdoor gas into the interior of the hollow body 114 via the valve uz' according to the required amount. In this embodiment, the outside air introduction pipe Uυ cannot pass outside the exhaust of the decompression equilibrium friction heat generation mechanism (3)' on the way to connect the inside and outside of the hollow chamber.
I'4r request. 37-1'7-9L? It has a so-called heat exchange mechanism shown in number d.

Therefore, the electric motor 16) is energized and the rotating body with rotating blades is
f4], a granule storage chamber (9) that ventilates gas such as air in the sealed hollow chamber {2} and the hollow chamber {2}
The air and other gases inside are gradually reduced in pressure by the suction and exhaust action of the rotating body (4), and the pressure difference between the interior and exterior of the hollow chamber (2) gradually increases, but when a certain pressure difference is reached, the pressure decreases. A state of equilibrium is reached and this state of equilibrium is maintained. The pressure difference between the inside and outside of the hollow chamber (2) in this equilibrium state depends on the magnitude of the rotational suction force of the rotating body (4), the diameter of the intake pipe (5}, and the rotating body (3).
)', this equilibrium state is maintained as long as the rotating action of the rotating body (4) continues. In this equilibrium state, air stagnates in the frictional heat generation part A in the rotation region of the rotary body +31, and the frictional action with the rotary body (4) continues to be repeated, so frictional heat is generated and the temperature gradually increases. Rise. This frictional heat is generated in the hollow chamber {(9
) and heats the room to the desired temperature.

In the process of this heating effect, when the outside air pipe is introduced from the outside air introduction l1}, the temperature inside the hollow chamber temporarily drops, but
The amount of vaporized steam in the hollow chamber (2) due to the amount of outside air introduced into the rotating body {
4}, the drying action is accelerated because the water is discharged and removed outside. The heated gas discharged from the reduced pressure equilibrium frictional heat generation mechanism {3} is transferred to a cylindrical cavity chamber (
7) Gases such as air are further heated because they are compressed in the cylinder chamber (I71), and the cylinder chamber becomes a hollow chamber {
2} Heat to a higher temperature. The heat in the cavity chamber 1'I) heats the heating plate (8) and the outer wall of the cavity chamber (7) and propagates into the granule storage chamber (9) via these.
Because of this, heat is stored in the heating plate (8). Heating plate (8)
The gas in the granule storage chamber (9) is heated by the propagation of heat into the granule storage chamber (9) through the outer wall of the cylindrical chamber (7), and the granule is heated inside the granule storage chamber (9). 131, the whole granule is directly heated by heat conduction through the granule 111 that is in contact with the heating plate (8) and the outer wall of the hollow chamber (7). In order to increase the amount of granules in contact with the heating plate (8) to increase the heating effect, and to increase the preheating effect, it is desirable to increase the surface area of the heating plate. Inside the hollow chamber (2) and inside the granule storage chamber (9), there is a reduced pressure equilibrium frictional heat generation mechanism (
3), it is heated and depressurized, but since the material to be dried is granules, there are voids between the granules and a hollow chamber (2)
By reducing the pressure in the granule storage chamber (≦1), the free moisture content of the granules increases, and the heating effect on the granules due to the rise in room temperature in the granule storage chamber (9) reduces the free moisture content of the granules. encourage the release of On the other hand, when the electric motor (6)' is penetrated and the rotating body (4)' is rotated, the gas exhausted from the cavity chamber (7) of the granule vacuum equilibrium heating device (1) filled in the closed hollow body is transferred to the rotating body. The exhaust pressure is gradually reduced by the suction and exhaust action of {4}', and the pressure difference between the inside and outside of the hollow body 14 gradually increases until a certain pressure difference is reached, reaching an approximately equilibrium state, and this equilibrium state is maintained. In this equilibrium state, the pressure difference between the inside and outside of the hollow body 114i is
', the diameter of the intake pipe 14+', and the rotating body +31-. Although determined by the size of the gap with ', this equilibrium state is maintained as long as the rotating action of the rotating body f31' continues.

In this equilibrium state, air stagnation occurs in the frictional heat generating portion A' within the rotating region of the rotating body 13+'.
3) Since the frictional action with '' continues to be repeated, frictional heat is generated and the temperature gradually rises.

This frictional heat is transmitted into the hollow body [14i] and heats the interior of the chamber to a desired temperature. In the process of this heating action, the outside air intake pipe (old)
When outside air is introduced from ', the temperature inside the hollow chamber temporarily decreases, but the vaporized steam inside the hollow chamber (1) by the amount of introduced outside air is discharged to the outside of the hollow body 114 by the rotating body (31). In this embodiment, the outside air introduction pipe (1
1)' has a heat exchange mechanism, so it is possible to eliminate heat loss with the intake gas and improve the heat generation effect. In this way, the gas exhausted from the cavity chamber (7) of the granule vacuum equilibrium heating device fi+ is exhausted into the hollow body ■, and then
Air is again drawn into the hollow chamber (2) from the outside air introduction pipe (11). When the gas inside the hollow body Ua is heated in the decompression equilibrium frictional heat generation climate (3)' as in this embodiment, the heating and decompression effect is further improved. Therefore, since the granule material vacuum equilibrium heating device is installed inside a hollow body, the heat generation and pressure reduction effect of the entire device and the release effect of free moisture from the granule material are increased, the electric motor can be made smaller, and the motor rotation can be operated at low rotation speed. It is possible to do so. Further, since the pressure difference between the inside of the granule material vacuum equilibrium heating device and the hollow body is reduced by the pressure difference between the device and the outside of the hollow body, it is possible to reduce the thickness of each wall. These effects are further enhanced by arranging many hollow bodies within the hollow body.

In other words, without requiring a direct heat source such as a conventional heater,
The energy for blowing air is converted into a suction depressurization effect based on the rotational action of the rotating body, and a frictional heat generation effect between the rotary body and the gas when the depressurization effect is balanced, and the energy is used without wastage to produce granules. It is possible to dry effectively.
