Description

[Detailed Description of the Invention] The object of the present invention is to uniformly distribute hot air sent from a hot air supply furnace to the inside of a roughing machine, and to send the hot air to the center of the roughing machine. The air guide network into which the hot air supplied by the duct from the hot air generating furnace is installed at the rear of the upper part of the roughing machine, and the air guide network is installed at the bottom of the air guide network. A cylindrical hot air blowing passage is communicated with the blowing port at the lower end of the hot air blowing passage. , relates to a hot air blowing control device for a tea making and roughing machine, in which the upper end edge of a damper plate for adjusting the volume of hot air is rotatably attached to a pivot; It is formed into a rectangular tube shape with both sides closed and the lower side open, and installed horizontally, and is installed on the inner surface of the upper plate of the air guide network at appropriate intervals along the direction of supply of hot air. A plurality of homogeneous distribution vanes are provided that are inclined in the direction of movement and have hot air passages on the lower side, and the lower end inlet of the hot air blowing path is located on the upper side of the roughing machine. The damper plate is characterized in that it communicates with the provided exhaust port through the inside of the roughing machine, and that a plurality of adjustment holes are provided through the lower edge of the damper plate.

According to this invention, the hot air sent from the hot air generating furnace through the duct is introduced into the air duct body provided at the upper rear part of the roughing machine, and while passing through the air duct body, , the hot air is distributed evenly by the uniform distribution blades,
While the hot air is being fed to the inside of the roughing machine, the hot air is will be sent to the dexterous center of the coarse crusher,
It is extremely useful because it can prevent floating water on the surface of tea leaves that occurs in the early stage of the rough rolling process in the rough rolling machine and asymmetric rough rolling at the latter stage of the rough rolling process.

Conventionally, in a tea making machine, hot air sent from a hot air generating furnace through a duct into an air guiding path body is directly blown into a roughing mechanism in the tea making machine through a 5-temperature hot air blowing path.

According to this conventional device, the heated air is distributed asymmetrically and
The air volume is not adjusted and it is blown into the roughening mechanism in the tea milling machine, which causes floating ice on the surface of the tea leaves at the beginning of the roughening process in the coarsening machine, and also prevents rough rolling in the later stage of the roughening process. There is a risk that it will become unbalanced.

On the other hand, the present invention eliminates the drawbacks of this conventional method.According to the present invention, hot air sent from a hot air generating furnace through a duct is connected to an air guide channel body provided on the upper side of the roughing machine. While passing through the inside of the air guide channel,
The hot air is uniformly distributed by the uniform distribution mechanism, and is sent into the hot air blowing path connected to the lower part of the air guide path, and the hot air is passed through the hot air blowing path. In the meantime, the air volume is adjusted and the air is blown into the roughening mechanism in the lower coarsening machine to activate the roughening process, which prevents floating water on the surface of the tea leaves that occurs in the early stage of the coarsening process in the coarsening machine and the latter stage of the coarsening process. This is extremely useful because it can prevent asymmetric roughness in the process.

In addition, the hot air blowing device in the conventional tea roughening machine has a horizontally long rolling barrel with a semicircular cross section and a stirring chamber formed by communicating a space above the rolling barrel, and the roughly axial center of the rolling barrel has a longitudinal axis. A rotating shaft is penetrated in this direction, and a number of kneading hands and rear hands are protruded from the rotating shaft, and the rotating shaft is rotated in a direction from the bottom of the kneading drum toward the upper front surface, and an ejection door is provided at a position near the front of the bottom of the kneading drum. In the tea processing machine, a hot air cylinder is installed near the front wall of the top of the stirring chamber, and the outlet is opened downward along the entire inner side of the front wall of the stirring chamber, or a method that uses hot air and infrared rays. As a tea leaf roughening machine, a rotating shaft with a rolling tool is installed in the center.
An air duct connected to a hot air generator at one end is installed on the back of the tea leaf drying drum with an exhaust port in the front of the top. A device that uses both hot air and infrared rays is known, which is characterized in that a hot air blowing tube is provided and an infrared gas burner is disposed between the blowing tubes.

However, with these known devices, control for uniformly sending hot air to the tea leaves within the kneading device is insufficient.

On the other hand, the invention of this application improves these conventional structures to uniformly send hot air to the tea leaves in the handle of the coarse rolling machine. The air guide path is formed into a rectangular tube shape with the upper and both sides closed and the lower side open, and installed horizontally. A plurality of uniform distribution vanes 5 are arranged at appropriate intervals along the direction of travel of the blades and have a hot air passage on the lower side, and the lower end of the hot air passage is connected to the It communicates with the exhaust port provided on the upper side of the rough kneading machine through the inside of the rough kneading machine,
Furthermore, the lower edge of the damper plate is provided with a plurality of adjustment holes, so that the hot air sent from the hot air generating furnace through the duct is passed through the air guide path provided at the upper rear of the roughing machine. While the heated air is introduced into the shell and passes through the air guide channel, the hot air is uniformly distributed by the uniform distribution vanes and is sent to the roughing machine. While the heated hot air passes through the hot air blowing path, the hot air is sent to the center of the coarse kneading machine by the plurality of adjustment holes provided at the lower edge of the damper plate. It is extremely useful because it can prevent floating water on the surface of tea leaves that occurs in the early stage of the rough rolling process in the rough rolling machine and asymmetric rough rolling at the latter stage of the rough rolling process.

The invention of this application will be explained next with reference to the drawings.
