Description

tea oven

technical field

The utility model belongs to the field of tea making machinery, in particular to a tea oven.

Background technique

Tea is deeply loved by the masses as a traditional and healthy drink. The main processing techniques of tea in the production process are generally spreading, finishing, rolling, stripping, and drying. Drying is an important process in tea making. The main purpose is to remove the moisture in the tea, and at the same time achieve the purpose of tea shaping and oxidation resistance. In the prior art, the drying of tea leaves is usually done in an oven. The tea leaves after being twisted and sorted are evenly spread on trays. There are horizontal plates arranged at intervals in the oven, and then the trays are placed on the horizontal plates in the oven. Stacked on top of each other, using charcoal brazier or electric energy for baking, the hot air in the oven flows upwards from the bottom, for the tea leaves on the sieve frame at different heights in the oven at the same time, the drying time must be different , After the tea is baked, the corresponding trays should be collected and then replaced. The staff needs to open the oven door back and forth to replace the trays, which greatly wastes labor.

Utility model content

Detailed ways

The utility model is further described in conjunction with accompanying drawings 1 to 5:

A tea oven, comprising an oven 10 for placing a tea drying net 20, the chamber of the oven 10 is connected to a heat source, the oven 10 is provided with a support bracket 30 for supporting the tea drying net 20, and the support bracket There is a space for inserting the tea drying net 20 between 30 and the bottom of the oven 10, and the motor 40 drives the lifting structure 50 to drive the tea drying net 20 placed at the bottom of the oven 10 to move upward. The tea drying net 20 is inserted between the supporting bracket 30 and the bottom of the oven 10, the motor 40 drives the lifting mechanism 50 to work and lift the tea drying net 20 to the supporting bracket 30, and the lifting mechanism 50 continues to lift the next tea drying net 20 on the return trip. Two tea drying nets 20 jack up the first tea drying net 20 and place it on the support bracket 30. Such reciprocating operation continuously stacks the tea drying nets 20 and lifts them to the top layer of the oven 10. After the tea is roasted The tea drying net 20 will be drawn out from the top to the bottom of the oven 10, which is convenient and quick, and there is no need to replace and place the tea drying net 20 manually, so as to prevent the staff from opening the box door back and forth to dissipate heat and ensure the drying quality of the tea.

One end of the support bracket 30 is hinged to the two symmetrical side plates 11 of the oven 10 and is in a horizontal suspension supporting working state or is forced to turn upwards relative to the hinge axis to a vertical avoidance position flush with the side plates 11 . The motor 40 drives the lifting mechanism 50 to work, and the tea drying net 20 between the supporting bracket 30 and the bottom of the oven 10 moves upwards, exerts an upward thrust on the supporting bracket 30, the supporting bracket 30 turns upwards relative to the hinged shaft core, and the lifting mechanism 50 works After finishing the return journey, the support holder 30 returns to the working state of horizontal overhang support to hold up the tea drying net 20 .

The motor 40 is arranged on the top of the oven 10, and the lifting structure 50 includes first, second, and third connecting rods 51, 52, 53. The first connecting rod 51 is placed on the top of the oven 10 and connected by a crank. The rod structure is connected to the rotating shaft of the motor 40, the second connecting rod 52 is arranged vertically on the outer sides of the two side plates 11 to connect with the two ends 51 of the first connecting rod, and the middle part of the third connecting rod 53 is connected to the end of the second connecting rod 52. The lower end is connected, and the two ends of the third connecting rod 53 are extended to the inside of the oven 10. Lifting rods 54 are arranged.
