Description

[Detailed description of the invention] (Industrial application field) The present invention uses hot air,
The present invention relates to an improvement in an aeration processing device that performs aeration processing using treated air such as hot air and cold air.

(Prior Art) Conventionally, an aeration processing device has a bottom portion provided with a receiving tray that can receive the granular material, a surrounding case forming a substantially sealed processing chamber is provided on the receiving tray, and a A high-pressure chamber is provided where processed air is forced into the system.
Several dozen injection nozzles are arranged in the high-pressure chamber so that the processing air can be injected toward the upper surface of the tray to disturb the granular material to be treated, and the tray is actively rotated.

(Problem that the invention aims to solve) Therefore, the structure is complicated because dozens of injection nozzles are arranged and the saucer is actively rotated, and dozens of injection nozzles are arranged inside the surrounding case. This makes cleaning work difficult, and the structure for actively rotating the tray and moving it up and down is also complicated. The number of nozzles and the number of driving parts are large, and therefore there is a disadvantage that the cost is high due to the cost of parts and assembly of parts.

(Means for Solving the Problems) The present invention is characterized in that the bottom of the aeration processing device is provided with a receiving tray that can receive the granular processing material, and on the receiving tray is provided an enclosing case that forms a substantially sealed processing chamber. A high-pressure chamber into which processing air is forcibly fed is provided on the surrounding case, and an injection nozzle is provided in the high-pressure chamber so as to spray the processing air toward the upper surface of the receiving tray and disturb the granular processing material. A screw blade is installed at the tip of the injection nozzle to generate a swirling flow in the processing air, and an input port for introducing the processing material into the processing chamber and an input port for sending the processing air to the outside are provided at the upper part of the processing chamber. Processing air whose temperature has been adjusted through a heating source by a circulation fan is forcibly fed into the high-pressure chamber from an inlet passage above the high-pressure chamber. The processing air is sent out from the delivery path, impurities are removed by a cyclone, and then circulated for a predetermined period of time by a circulation fan.

(Function) In the aeration treatment device for granular materials configured as described above, when a predetermined amount of granular materials to be aerated is put into the inlet, it naturally falls and collects in the tray, and then the circulation fan and heating source are turned off. When the high-pressure chamber is activated, the process air whose temperature has been adjusted through a heating source is forced into the high-pressure chamber by a circulation fan from the inlet path of the high-pressure chamber, and then passes through the injection nozzle and is heated by the action of the rattle shape at the tip of the injection nozzle and the screw blade. By generating a swirling flow, the granular material to be treated is disturbed and aerated, and the treated air passes through the delivery path, removes impurities in a cyclone, and is then circulated again by the circulation fan for a predetermined period of aeration. It acts to do the following.

(Example) Next, the configuration of an example of the present invention will be described with reference to the drawings.

The bottom of the aeration processing device is provided with a cylindrical tray 1 capable of receiving granular materials, and the tray 1 consists of a cylindrical tray body 2 and a tray lid 3 whose bottom surface can be opened and closed, using a pin 4 as a fulcrum for opening and closing. Pull the saucer lid 3 downward from the outside to open it, and to close it, pull the saucer lid 3 onto the saucer body 2.
When pressed, the joint between the saucer body 2 and the saucer lid 3 engages to close. A surrounding case 5 that forms a nearly sealed processing chamber is provided above the saucer 1, and the surrounding case 5 is made of transparent heat-resistant glass, and the lower part is the saucer body 2.
The upper part is in close contact with the cylindrical body 6. A high-pressure chamber 7 into which the processing air A is forcibly fed is provided integrally with the cylinder 6 at the top of the cylinder 6, and the processing air A is injected into the high-pressure chamber 7 toward the top surface of the receiving tray 1 to form particles. An injection nozzle 8 is provided integrally with the high-pressure chamber 7 and close to the upper surface of the saucer 1 so as to be able to disturb the processing material R, and the tip of the injection nozzle 8 is shaped like a flap to generate a swirling flow in the processing air A. Attach the screw blade 9 and the triangular pyramid 10. Further, the cylindrical body 6 is provided with an input port 11 through which the granular material is introduced and allowed to fall naturally into the receiving tray 1, and a discharge path 12 at a position opposite to the input port 11. Processed air A, whose temperature has been adjusted by a circulation fan 13 through a heating source 14 such as a burner or heater, is forcibly fed into the high pressure chamber 7 from an inlet passage 15 at the top of the high pressure chamber 7, passes through an injection nozzle 8, and generates a swirling flow. Thereafter, the treated air A is sent out from the delivery path 12, and after impurities are removed by the cyclone 16, it is circulated again by the circulation fan 13. When the ventilation process is completed, the process air A is discharged to the outside by an exhaust fan 17.

Next, the operation of this embodiment will be explained.

In the aeration processing device configured in this way, when a predetermined amount of granular material to be aerated is put into the input port 11, it naturally falls and accumulates in the tray 1, and then when the circulation fan 13 and heating source 14 are activated, Processed air A whose temperature has been adjusted through a heating source 14 by a circulation fan 13 is forcibly fed into the high pressure chamber 7 from an inlet passage 15 of the high pressure chamber 7, and then passes through an injection nozzle 8 to form a lattice shape at the tip of the injection nozzle 8 and a screw blade. 9 and the triangular pyramid 10 generate a swirling flow in the treated air A, which disturbs the granular material R and acts as an aeration treatment. After being removed, the circulation is repeated again by the circulation fan 13 and aeration processing is performed for a predetermined time, and then the circulation fan 13 and the heating source 1
4 is stopped, and then the exhaust fan 17 is activated to exhaust the hot air in the processing chamber, and then the exhaust fan 17 is stopped, thereby completing the ventilation treatment of the granular material R. The granular processed material R for which the aeration process has been completed is placed in the saucer lid 3.
When pulled downward, the saucer lid 3 opens and can be taken out.

(Effects of the invention) The present invention provides a cylindrical receiving tray capable of receiving granular materials at the bottom of the aeration processing device, a surrounding case forming a nearly sealed processing chamber on the receiving tray, and a surrounding case that forms a nearly sealed processing chamber. A high pressure chamber into which treated air is forcibly fed is provided on the case integrally with the cylindrical body, and the high pressure chamber is configured to inject the treated air toward the upper surface of the receiving tray to disturb the granular treated material. The tip of the injection nozzle is shaped like a trumpet and is equipped with a screw blade that generates a swirling flow in the processing air, and the processing air whose temperature has been adjusted through a heating source is forcibly fed into the high pressure chamber by a circulation fan, and the injection nozzle is After generating a swirling flow, the treated air is sent out from the delivery path, impurities are removed by a cyclone, and then the air is circulated again by a circulation fan. As a result, the present invention has a fixed injection nozzle with a trumpet-shaped tip and a screw blade attached to it. It is possible to generate a swirling flow to repeatedly disturb the granular material, thereby achieving uniform aeration treatment, and by setting the temperature of the heating source, it is possible to achieve uniform aeration treatment at a set temperature.
