Description

Technical Field

[0001] The invention relates to the technical field of tea processing, and in particular to fermentation equipment for tea processing. Background Art

[0002] During the fermentation process of tea, the tea polyphenols in the tea are oxidized by oxygen in the air to form oxidation products, and the proteins, polysaccharides, etc. in the tea are catalyzed by enzymes to form enzymatic hydrolysis products. The oxidation products and enzymatic hydrolysis products of tea polyphenols will produce various aromatic substances, thus forming the aroma of the tea. At the same time, the color, taste and nutritional components of the tea are different due to the different degree of fermentation. Therefore, tea fermentation is an important link that affects the quality of tea.

[0003] Chinese patent CN15615622660413.6 discloses a fermentation device for tea processing, wherein tea leaves are placed inside a fermentation cylinder through a first sealed inlet and outlet on a frame and a second sealed inlet and outlet on a fermentation cylinder, the first sealed inlet and outlet and the second sealed inlet and outlet are closed, the temperature and humidity inside the frame 1 are controlled by a sealed valve, a heater or a refrigerator, and a water vapor generator, an oxygen generator arranged in the frame 1 provides oxygen so that the tea leaves in the fermentation cylinder can come into contact with oxygen, the output end of the motor is fixedly connected to the rotating shaft; the rotating shaft is fixedly connected to the fermentation cylinder; the motor drives the rotating shaft and the fermentation cylinder to rotate, so that the tea leaves continuously move in the fermentation cylinder, so that the tea leaves can come into contact with more oxygen in the fermentation cylinder, thereby increasing the fermentation speed.

[0004] Tea leaves will continuously produce carbon dioxide during the fermentation process. Since the frame is in a sealed state, the carbon dioxide produced by the tea leaves cannot be discharged from the frame 1, and the carbon dioxide concentration in the frame 1 gradually increases. Since the density of carbon dioxide is greater than that of air, it will sink to the bottom of the frame. As the carbon dioxide concentration in the frame 1 gradually increases, the tea leaves at the bottom of the fermentation cylinder will come into contact with the carbon dioxide. The carbon dioxide accelerates the metabolism of the microorganisms in the tea leaves and speeds up the fermentation. However, this rapid fermentation process may cause the fermentation process of the tea leaves to lose balance, produce some unpleasant odors or tastes, and cause the tea leaves to lose their original aroma and taste. In addition, an excessively high carbon dioxide concentration may damage the beneficial ingredients in the tea leaves, resulting in a decrease in the nutritional value and quality of the tea leaves.

[0043] (1) The present invention starts the motor, which drives the fermentation cylinder to rotate, so that the tea leaves are turned in the fermentation cylinder. Oxygen enters the fermentation cylinder through the ventilation holes on the fermentation cylinder and fully contacts with the oxygen in the fermentation cylinder. The density of carbon dioxide generated by the fermentation of tea leaves is greater than that of oxygen, and it sinks to the bottom of the frame and enters the treatment box from the first connecting pipe. Solid sodium hydroxide is placed between the filter plates. The carbon dioxide discharged from the first connecting pipe reacts with the solid sodium hydroxide, and the solid sodium hydroxide deliquesces. The partition plate is inclined. The liquid generated by the deliquescing reaction of the solid sodium hydroxide moves toward the through hole under the action of gravity and enters the lower end of the treatment box from the through hole. The heating box heats the treatment box, so that the water in the solution entering the treatment box evaporates, crystals precipitate, and the water vapor enters the frame from the second connecting pipe, which can reduce the amount of water vapor generated by the water vapor generator and save energy consumption; at the same time, it reduces the discharge of carbon dioxide, reduces carbon emissions, and protects the environment.

[0044] (2) The present invention drives the rotating shaft to rotate by a motor. When the motor stops, the feed port is located directly below the discharge end of the feed hopper. The staff opens the feed door and uses a tool to pull the first baffle plate out toward the feed door through the first plug-in slot, and the feed port is opened. The diameter of the feed port is larger than the diameter of the discharge end of the feed hopper. The feed valve is opened, and the tea leaves in the storage box enter the feed funnel, the feed port and the rotating drum in sequence, which is convenient for loading. The tea leaves are located between the two second fixed plates. After a proper amount of tea leaves are loaded into the rotating drum, the feed valve is closed, and a tool is used to return the first baffle plate to the initial position through the first plug-in slot. The feed port is blocked by the first baffle plate to prevent the tea leaves in the drum from leaking out of the feed port when the rotating drum rotates. The feed door is closed, and the frame is not connected to the outside. The tea leaves begin to ferment.

[0045] (3) The present invention drives the rotating shaft to rotate by a motor. When the motor stops, the discharge port is located directly above the feed end of the discharge funnel. The discharge valve is opened, and the staff opens the discharge door and uses a tool to pull out the second baffle plate toward the discharge door through the second plug-in slot, and the discharge port is opened. The diameter of the discharge port is smaller than the diameter of the feed end of the discharge funnel. The fermented tea leaves in the rotating drum enter the discharge port, the discharge funnel and the discharge pipe in turn, and are moved out of the frame to facilitate unloading. After the tea leaves in the rotating drum are completely unloaded, the discharge valve is closed, and a tool is used to return the second baffle plate to its initial position through the second plug-in slot.
