Hot air-type tea leaf enzyme-deactivating machine with heat recycling function

Abstract

The invention discloses a hot air-type tea leaf enzyme-deactivating machine with a heat recycling function. The hot air-type tea leaf enzyme-deactivating machine comprises a box body, wherein supporting legs are fixedly connected to the lower surface of the box body; a box cover is movably connected to the upper side of the box body through hinges; hot air blowers are fixedly connected to the inner wall of the box body; a retainer ring is fixedly connected to the lower side of the inner wall of the box body; an elastic net is fixedly connected to the inner wall of the retainer ring; a drivingdevice is fixedly connected to the bottom of the inner wall of the box body; one side of the driving device is fixedly connected with the lower surface of the elastic net. A speed reducing motor is arranged for driving a wheel disc to rotate, the wheel disc rotates to drive a toothed rod to move down because of engagement of a toothed rail and the toothed rod, and the toothed rod moves down to pull a fixing block so as to deform the elastic net; when the toothed rail rotates to an empty position, the toothed rail and the toothed rod are disengaged, so that the effect of limiting the toothed rod is eliminated, and tea leaves are vertically thrown up by the elastic net; by spreading out the tea leaves, the effect of preventing the tea leaves from being heated nonuniformly due to accumulationof the tea leaves is achieved.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a hot-air tea greening machine with the function of recovering heat energy. Background technique [0002] The main purpose of greening is to destroy and passivate the oxidase activity in fresh leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, and prevent discoloration during drying. At the same time, it emits green odor and promotes the formation of good aroma. Most of the fixing machines use microwave fixing machines, drum fixing machines, gas frying machines and hot air tea fixing machines. Because the tea leaves are stacked together, the internal tea leaves are less effective in curing, and the outer tea leaves are heated too high, which makes the curing uneven. Change the position so that the tea leaves on the inner and outer layers are heated evenly, but the tea leaves are often broken during the turning process, making t...
