Description

Technical Field

[0001] The utility model relates to the technical field of tea processing auxiliary devices, in particular to a tea withering device capable of adjusting air outlet uniformity. Background Art

[0002] Withering is a process in tea processing, and the withering trough is a device designed based on the principle of hot air convection conduction. It uses hot air as a drying medium and, with the pressure of a ventilator, passes through the fresh tea leaves spread on the trough. After the tea leaves are heated, the moisture in the leaves evaporates and gradually withers. And because the withering temperature cannot be too high, so as not to destroy the activity of the enzyme and affect the quality of the finished tea, a cold air door is set on the hot air pipe to adjust and limit the temperature. Since the air inlet of the current withering trough is generally set at the lower tail, the hot air will stick to the inner bottom of the withering trough until it rolls back to the front side of the withering trough. This results in uneven hot air being received by the tea leaves in various parts of the withering trough, which in turn affects the withering quality. This is the main problem currently faced.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] Example:

[0020] Reference Figure 1The present embodiment provides a tea withering device capable of adjusting the uniformity of air outlet; it comprises a trough body 1 with an opening at the top; a hot air blower 2 is provided at the rear side of the trough body 1; a plurality of guide grooves 3 are provided on the left and right sides of the inner cavity of the trough body 1; the guide grooves 3 are arranged vertically, and a height adjustment component 4 is provided at the guide grooves 3; a pad 5 is further installed in the inner cavity of the trough body 1; the pad 5 is arranged against the top of the height adjustment component 4, and its height relative to the inner bottom surface of the trough body 1 is limited by the height adjustment component 4; a guide plate 6 is provided on the pad 5.

[0021] The guide grooves 3 are arranged in pairs; a cross bar 7 is installed between each pair of guide grooves 3; the cross bar 7 can move on the guide groove 3, and the cross bar 7 is placed on the top of the height adjustment component 4 and is in contact with the pad 5.

[0022] The height adjustment component 4 is a segmented, electrically controlled telescopic rod structure powered by an external power supply, and the control switch of the height adjustment component 4 is located on the outer wall of the tank body 1 at a position corresponding to the guide slot 4. It should be noted that although the height adjustment component is limited to an electrically controlled telescopic rod in this embodiment, other devices that can correspond to the electrically controlled telescopic rod and can lift the pad upward are also applicable.

[0023] The pad 5 is made of a deformable and rollable material; the width of the pad 5 is consistent with the width of the inner cavity of the trough body 1; a rotating shaft 8 is installed on the front end face of the inner cavity of the trough body 1 through a pair of ear plates; one end of the pad 5 is connected to the position in the inner cavity of the trough body 1 below the air outlet of the hot air blower, and the other end is rolled up on the rotating shaft 8.

[0024] One end of the rotating shaft 8 is arranged to pass through the side wall of the trough body 1, and a handle capable of controlling its rotation is installed on the protruding end.

[0025] A cover plate 9 is further provided in the inner cavity of the tank body 1 ; the cover plate 9 is cantilevered, with one end hingedly mounted on the front end surface of the inner cavity of the tank body 1 and the other end resting on the pad 5 .

[0026] A plurality of positioning grooves are formed on the backing plate 5 , and the guide plate 6 is detachably mounted on the backing plate 5 through the positioning grooves.

[0027] When using the utility model device in this embodiment, it is only necessary to adjust the extension distance of each electric telescopic rod at the control end of the electric telescopic rod corresponding to each group of guide grooves according to the needs of use, and the movement of the electric telescopic rod will drive the pad to move upward synchronously to form a slope surface. Since the pad is a retractable structure made of deformable material, the change of its working length can be achieved by unwinding the pad by rotating the rotating shaft. During this process, the cover plate is always placed on the upper top of the pad to seal the recess on the front side of the groove body. After the length adjustment of each electric telescopic rod is completed, the guide plate can be installed on the positioning groove of the half point.
