Problems solved by technology

[0003] In the prior art, when the commonly used tea greening machine for health-preserving tea processing is in use, the tea leaves are laid flat on the conveyor belt of the conveyor, and the conveyor belt transports the tea leaves to the position of the microwave heating box to heat and green the tea leaves, and the tea leaves are laid flat on the The conveyor belt has a certain thickness, and the tea leaves block each other. The tea leaves near the microwave heating box are heated better, while the tea leaves attached to the conveyor belt are poorly heated due to the blocking of the tea leaves near the microwave position, resulting in tea leaves on the conveyor belt. Uneven heating reduces the quality of tea leaves
[0004] In order to solve the above problems, Chinese patent CN201921811036.2 discloses a greening machine for health-preserving tea processing. By setting a geared motor, a rotating shaft, a round rod and a baffle, when in use, the conveyor belt of the conveyor runs to accumulate tea leaves on the baffle. On the top, the deceleration motor drives the rotating shaft to rotate, and the rotating shaft drives the movable plate and the round rod to rotate, and the tea leaves are moved to the position of the through groove of the baffle plate. The gap between the bars falls on the conveyor belt of the conveyor, so that the tea is heated evenly, and the tea leaves are moved through the movable plate and the round bar on the rotating shaft, and the tea falls from the gap between two adjacent bars. To the conveyor belt of the conveyor, the tea is heated evenly, and the effect of improving the quality of the tea is achieved, so as to solve the problem in the prior art that the tea leaves have a certain thickness on the conveyor when the current common tea de-greening machine for health-preserving tea processing is in use. , the uneven heating of the tea leaves on the conveyor reduces the quality of the tea leaves
[0005] The green fixing machine disclosed in this patent, in the process of actual use, has the problem that the tea leaves in the middle of the conveyor belt are still piled up in the middle after being dispersed. It is impossible to solve the problem of uneven heating of tea leaves on the conveyor and reduce the quality of tea greening

Embodiment Construction

[0041] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0042] Such as Figure 1-11 As shown, a tea processing device through microwave heating and greening includes a frame 10, a transmission mechanism 3 arranged on the frame 10 for transporting tea leaves, and a transmission mechanism arranged on the frame 10 and located in the transmission path of the transmission mechanism 3. The microwave heating mechanism 5 used for heating the tea leaves on the transport mechanism 3 can realize the greening of the tea leaves through the heating of the microwave heating mechanism 5 .

[0043]The frame 10 is U-shaped with an upward opening, and the transmission mechanism 3 includes two rotating shafts rotatably supported in the U-shaped frame 10 and located at both ends of ...

Abstract

The invention provides a tea processing device capable of deactivating enzymes by microwave heating. The device comprises a U-shaped rack with an upward opening, a transmission mechanism arranged in the U shape of the rack and used for conveying tea leaves, and a microwave heating mechanism arranged on the rack, positioned on a transmission path of the transmission mechanism and used for heating the tea leaves on the transmission mechanism; and enzyme deactivation of the tea leaves can be realized through heating. The transmission mechanism comprises two rotating shafts which are rotatably supported in the U shape of the rack and located at the two ends of the rack in the length direction of the rack respectively, belt wheels arranged at two ends of each rotating shaft, two belts enablingthe corresponding belt wheels to be in transmission connection in the length direction of the rack, and a plurality of storage boxes, wherein the two ends of each storage box are supported on the twobelts in the width direction of the rack, the multiple storage boxes are arranged in the conveying direction at equal intervals, and openings of the storage boxes are opposite to the belts. The devicecan realize automatic enzyme deactivation of the tea leaves, and is high in enzyme deactivation quality.

Description

technical field [0001] The invention relates to the field of automatic processing of tea leaves, in particular to a tea processing device which heats and completes greens by microwaves. Background technique [0002] Finishing is one of the primary processes of green tea, yellow tea, dark tea, oolong tea, Pu'er tea, and some black teas. The main purpose is to destroy and passivate the oxidase activity in fresh leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make the tea soft, easy to knead and form, and emit green odor at the same time Taste, promote the formation of good aroma. [0003] In the prior art, when the commonly used tea greening machine for health-preserving tea processing is in use, the tea leaves are laid flat on the conveyor belt of the conveyor, and the conveyor belt transports the tea leaves to the position of the microwave heating box to heat and green the tea leave...
