Description

[Detailed Description of the Invention] This invention solves the following problems: dissipation of aroma, which is the life of tea making, floating water phenomenon in the early stage of the process, damage to tea leaves, uneven roughness in the late stage of the process,
Hot air sent through a duct from a hot air generating furnace is intended to prevent tea leaves and small pieces of tea from scattering outside the machine, as well as to improve the yield of tea production and the value of tea making equipment. The hot air is introduced into the air guide body provided at the upper rear of the body of the roughing machine, and the hot air is sent into the hot air blowing path provided at the bottom of the air guide body, and the heated air is Controlled by a damper from the lower end of the wind blowing path,
A type of method in which the tea leaves are placed in the barrel of a coarsening machine, and within the barrel, the tea leaves are subjected to rough manipulation by a plurality of handlers and rope handlers that are rotated by the rotation of a rotating shaft. In the tea processing machine, the air guiding passage body is configured to have a cylindrical cross-section with the upper and both sides sealed, and a group of uniformly distributed slanted blade plates are arranged in parallel and protruding from the inner surface of the upper plate. The introduced hot air blown into the air guide channel is uniformly distributed by the uniformly distributed inclined vane group and sent to the lower end of the air outlet. It is controlled by the damper provided at the top of the container to cause the air to be blown into the chamber of the roughing machine, and the exhaust gas is discharged from the exhaust port provided at the upper part of the container, and the damper is moved in the closing direction. ,
It is characterized by a plurality of adjustment holes provided at the lower edge of the damper to send the hot air to the center of the heating device, and the hot air sent from the hot air generating furnace. The wind was controlled by installing a uniform hot air supply mechanism behind the top of the heating machine, and setting the speed of the hot air outlet and the tea leaf movement speed inside the machine (mechanical mechanism speed) = 1.3 m/sec, and by operating the damper and heating. A heating air duct with a uniform air supply mechanism and a conventional mechanical motor transverse speed adjustment are used to control the thermal and moisture properties (specific heat, specific gravity, heat conduction) of the roughened tea leaves, which change in the early, middle, and late stages of the roughening process. It facilitates the supply of hot air greenness and hot air flow rate that match the shape (surface area) and the shape (surface area) of tea leaves. It can prevent spoilage, uneven roughness, light leaves, and small pieces of tea from scattering outside the machine in the latter stages of the process, and it also improves the yield of tea production and the value of the product. This is extremely useful as it can improve the effective utilization of the amount of hot air sent from the furnace.

Conventionally, there was a horizontally elongated body with a semicircular cross section and a rope azusa chamber formed by passing a space above it. A tea processing machine is equipped with a large number of bare hands and quick hands, and the rotary shaft is operated and rotated from the bottom to the upper front, and a take-out door is provided at the bottom of the barrel near the front. A hot air blower is installed in the tea processing machine, which has a heating vent installed on the front wall of the dispersion room, and its outlet is directed downward along the entire inner side of the front wall of the dispersion room. An attached rotating shaft was built, and an air passageway was installed on the back of the tea leaves with an exhaust outlet on the front of the teacup, one end of which was connected to a hot air generator. A large number of hot air blowing tubes are installed to forcefully send hot air along the tube, and an infrared gas burner is installed between the blowing tubes, and a tea leaf coarsening machine that uses hot air and infrared rays is installed, or a hot air generating furnace is passed through a duct. The sent hot air is introduced into the air guide channel body provided on the upper side of the roughening machine, and while passing through the air guide channel 8, the hot air is uniformly distributed by a uniform distribution mechanism. At the same time, the heated air is sent into the hot air blowing passage installed at the bottom of the air guide passage body, and while the hot air is passing through the overflow hot air blowing passage, the air volume is adjusted to cool the air at the bottom. A method for controlling hot air blowing in a tea processing machine is known, which is characterized by blowing into a roughening mechanism in the machine to perform rough operation.

However, in contrast to these conventionally known devices, the invention of the present application uses an air guide path provided at the upper rear part of the body of the steamer to direct hot air sent from a hot air generating furnace through a duct. It is introduced into the hot air blowing passage installed at the bottom of the air guide passage body, and is controlled by a damper from the lower end of the hot air blowing passage. In a tea processing machine, the tea leaves are caused to be blown into the container body, and the tea leaves are subjected to rough operation by a plurality of handlers and follower hands, which are rotated by the rotation of a rotating shaft. The air guide arm has a cylindrical cross-section with the upper and feed sides closed, and a group of evenly distributed inclined vanes arranged in parallel on the inner surface of the upper plate allows the introduced hot air to be distributed within the air guide body. When passing through, the air is evenly distributed and controlled by a damper from the inlet at the lower end of the inlet channel, and is blown into the container of the roughing machine, and then exhausted from the outlet provided at the upper edge of the vessel body. When the damper is moved in the opening direction, the hot air is sent to the center of the body of the dryer by means of a plurality of adjustment holes provided at the lower edge of the damper. Therefore, the dissipation of aroma, which is the life of tea manufacturing, the floating water phenomenon, damage to tea leaves in the early stage of the process, uneven roughness, light leaves,
This is extremely useful because it prevents small pieces of tea from scattering outside the machine, improves the yield of tea production, and improves the value of the product. The invention of this application will now be described with reference to the drawings.
