Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tea packaging, especially to a tea canning oxygenation device. BACKGROUND

[0002] The big Hongpao tea usually needs to be stored for a period of time to make its internal substances naturally oxidize and mellow in the presence of oxygen, so as to form a unique quality flavor for drinking. In addition, the big Hongpao tea needs to be baked several times to form a unique "rock bone flower fragrance", commonly known as "caramel high-heat fragrance" during the production process. However, some consumers are not used to drinking the big Hongpao tea with the "high-heat caramel fragrance", and even the tea will cause the body to be on fire after being drunk. Therefore, the big Hongpao tea needs to be naturally stored and annealed for 1-2 years before being drunk. At present, the traditional natural storage method is still used in the big Hongpao tea production area for annealing and mellowing. During the natural storage, the tea needs to be ventilated with the external environment to a certain extent, so as to perform the oxidation reaction and accelerate the annealing and mellowing process. Practice shows that although the annealing and mellowing process can achieve good results, it still has the problems of long annealing and mellowing time, large occupation of warehouse space, easy erosion of water vapor, light, heat and microorganisms during storage, and easy quality deterioration risk. Therefore, it is necessary to research a canning oxygenation device for the big Hongpao tea annealing and mellowing, so that the tea can be oxidized in a clean environment after being sealed.

[0011] Fig. 2 It is the enlarged schematic view of the oxygenator in the utility model. DETAILED DESCRIPTION

[0012] The embodiment, such as Figs. 1-2 As shown in a kind of tea caddy packing oxygenation device, including oxygen machine 1 and vacuum machine 2, cover 3 on tea caddy, vacuum pipe 4 is arranged between vacuum machine 2 and cover 3, and tea caddy is vacuumized by vacuum pipe 4. Cover 3 is also provided with oxygenator 5, and oxygen is filled into tea caddy by oxygenator 5.

[0013] Specific structure is described as follows:

[0014] The cover 3 is stainless steel circular cover, and its diameter can be adjusted according to the size of tea caddy. To facilitate control cover 3 moves up and down and combines with tea caddy and separates, cover 3 is connected and is provided with the mechanical arm 9 that drives cover 3 to move up and down, the mechanical arm 9 preferably adopts telescopic pneumatic cylinder 91 to drive mechanical arm 9 telescopic, when tea caddy moves to the lower side of cover 3, mechanical arm 9 drives cover to move downward and make cover 3 buckle the tea caddy spout, when oxygenation is completed, mechanical arm 9 drives cover 3 to move upward and separates with tea caddy.

[0015] In order to prevent the tea fur and small leaves from blocking the vacuum pipe 4 when vacuumizing, the cover 3 is further provided with a vacuum branch pipe 41 which is connected with the vacuum pipe 4, and the vacuum branch pipe 41 is uniformly provided with 40-50 mesh laser micro-holes, is a stainless steel pipe with a diameter of 0.5 cm, and is closed at the end to extract the air in the tea canister through the laser micro-holes. The vacuum machine 2 is a J-V05 single-chamber vacuum machine, the air extraction speed of which is 5.5 L / S, and the limit negative pressure is 0.1 MPa, so that the air in the tea canister can be efficiently extracted.
