The present invention relates to a vibration fluidized drying / cooling device.

As shown in FIG. 4, the vibration fluidized drying / cooling device is configured such that the vibration fluidized drying / cooling device 51 is vibrated obliquely upward by a vibration motor (not shown) and supplied to one end in the fluid chamber 55a. The granule is transferred to the other end with vibration. At that time, hot air or cold air is blown from the blower 52 into the flow chamber 51a. Thereby, a granular material becomes a fluid state and is dried or cooled.

The hot air supplied to these fluid chambers 51a is discharged from the exhaust port 53 provided at the top of the vibration fluidized drying / cooling device 51 through the tube (not shown) to the dust collector 54, and from the dust collector 54 to the outside through the wind fan 55.

However, when the fine powder in these granular materials is expensive, such as pharmaceuticals and foods, as described above, if the fine powder is collected in a dust collector and discarded, the processed material at the time of the drying or cooling treatment Yield is poor, leading to increased costs.

Further, since the exhaust air is collected in the dust collector 58 from the exhaust port 57 of the vibration fluidized drying / cooling device 52 through the pipe line, equipment such as a pipe line and a dust collector is required, and the equipment cost and the running cost are required. .

Therefore, the present invention solves the above technical problem, and can dry or cool the fine powder in the granular material to the outside, can be dried or cooled, has a good yield at the time of processing, and has a large dust collector or the like. The object of the present invention is to provide an unnecessary vibration fluidized drying / cooling device.

The cylindrical guide frame body is an oscillating fluidized drying / cooling device having a height higher than the height at which the fine powder in the granular material rises.

According to a second aspect of the present invention, a cylindrical flexible member is connected between the opening of the fluid chamber and the lower end opening of the cylindrical guide frame, and the cylindrical guide frame is a support leg. Thus, the vibration fluidized drying / cooling device according to claim 1 is supported separately from the fluidizing chamber.

The invention according to claim 3 is the vibration fluidized drying / cooling device according to claim 1 or 2, wherein the cylindrical guide frame body has an open shape with an inner diameter expanding from the bottom to the top.

Moreover, invention of Claim 4 was set as the vibration fluid drying / cooling apparatus in any one of Claims 1-3 which covered the filter on the upper surface opening part of the said cylindrical guide frame.

The invention according to claim 5 is the vibration fluidized drying / cooling device according to any one of claims 1 to 4, wherein all or part of the cylindrical guide frame body is configured by a member that can visually recognize the inside.

According to the first aspect of the present invention, since the cylindrical guide frame is provided above the flow chamber of the vibration fluidized drying / cooling device, the hot air and the cold air blown to the powder particles in the fluid chamber become exhaust air. The air is exhausted directly from the upper end opening of the cylindrical guide frame to the outside air. However, since the cylindrical guide frame has a height higher than the height at which the fine powder in the granular material rises, the fine powder in the granular material does not flow out from the upper end opening of the cylindrical guide frame. .

Therefore, unlike the conventional method, the amount of powder particles is not reduced during the drying or cooling process, and the process yield is good. Therefore, this is particularly suitable for those having an expensive powder.

In addition, it is not necessary to provide a dust collector or a pipe line as in the conventional case, so that the cost of equipment can be reduced and the running cost can also be reduced.

According to the invention of claim 2, since the cylindrical guide frame body is connected to the flow chamber via the cylindrical flexible member and has the support leg, the vibration of the flow chamber is absorbed by the cylindrical flexible member. The vibration of the fluid chamber is not transmitted to the cylindrical guide frame, and the cylindrical guide frame can be supported firmly and can be made durable.

According to the invention of claim 3, since the cylindrical guide frame is opened in a trumpet shape upward, a space where the finely processed product can fall around the exhaust air is exhausted upward. Therefore, the granular material is not disturbed by the exhaust air blown from below, and easily falls by its own weight.

According to the invention of claim 4, since the upper end opening of the cylindrical guide frame is closed with a filter, the crushed pieces whose powder particles are crushed by vibration are collected by the filter and are not scattered outside. .

According to the invention of claim 5, since all or a part of the cylindrical guide frame body is composed of a member that can visually recognize the inside, it is confirmed to what height the granular material is scattered. This makes it possible to adjust the amount of hot or cold air blown, and it is easier to prevent the powder particles from scattering to the outside.

The present invention provides a fluid chamber that vibrates and transports powder particles from one to the other, and blows hot or cold air from the outside into the fluid chamber to fluidize and dry or cool the particles. In the vibratory fluidized drying / cooling apparatus to be processed, an opening is provided on the upper end surface of the fluid chamber, and a cylindrical guide frame that is open at the top and bottom is connected to the opening via a cylindrical flexible member. The cylindrical guide frame has a height that is higher than the height at which the fine powder in the granular material rises, and is supported separately from the fluid chamber by a support leg.

Thereby, it is not necessary to provide a conventional dust collecting device, the equipment cost and running cost are reduced, and the powder particles are not washed away to the outside, so that the yield is good.

Further, vibration motors 4 are provided on both sides of the main body 1, and the main body 1 vibrates by these vibration motors 4. As shown in FIG. 1, the inner upper portion of the main body 1 is a flow chamber 5, and the lower portion is a blow chamber 6. The flow chamber 5 and the blow chamber 6 are perforated plates 7 made of punching metal or the like. The air in the blow chamber 6 is blown into the fluid chamber 5 through each small hole of the perforated plate 7.

In addition, the main body 1 is divided into two parts in the vertical direction between the flow chamber 5 and the air blowing chamber 6 and can be freely opened. The upper end surface of the flow chamber 5 which is the upper end of the main body 1 is open, and a tubular flexible member 9 made of rubber or the like is connected to the opening, and further, the upper end opening of the tubular flexible member 9 is The lower end opening of the open cylindrical guide frame body 10 whose inner diameter and outer diameter increase as it goes to is connected.

In the above configuration, in order to dry the granular material, the vibration motor 4 is driven and rotated, and the flow chamber 5 vibrates obliquely upward. When the granular material is introduced into one end of the fluid chamber 5 from the raw material inlet 13, the particulate matter is transferred on the porous plate 7 toward the other end of the fluid chamber 5 by the vibration.

At the same time, hot air is sent from the blower 17 to the blower chamber 6 from the blower port 16. As a result, hot air is blown into the fluid chamber 5 from a large number of small holes in the perforated plate 7, and these powder particles are dried while flying up the powder particles on the perforated plate 7.
