Description

TECHNICAL FIELD

[0001] The utility model relates to black tea processing technical field especially, and is concerned with a controllable black tea drying machine. BACKGROUND

[0002] In the field of black tea processing, the drying machine is one of the important equipment. The traditional black tea drying machine is usually a simple roller structure. In the drying process, the tea leaves are only rolled inside the roller to realize the contact drying with the hot air.

[0003] However, this traditional drying method has many problems. During drying, the tea leaves only roll naturally inside the roller, and the contact with the inner wall of the roller is not sufficient and lacks effective extrusion. The surface of the tea leaves is easy to form a layer of water vapor, which hinders the rapid evaporation of internal moisture, resulting in slow drying speed and low drying efficiency, and it is difficult to ensure uniform heating of the tea leaves, which may cause some tea leaves to be over-dried while others are not dried properly, seriously affecting the quality of black tea. In addition, the structural design of the traditional drying machine is not conducive to the cleaning and maintenance of the equipment inside. After long-term use, residual tea leaves and other impurities are easy to accumulate inside the roller, breeding harmful substances such as bacteria, which not only affects the quality of the next batch of black tea, but also may damage the equipment and shorten the service life of the equipment. At the same time, the traditional drying machine loses a lot of heat during the drying process, making it difficult to maintain a stable constant temperature environment, and more energy is needed to maintain the required temperature for drying, increasing the production cost.

[0004] Therefore, we propose a controllable black tea drying machine. CONTENT OF THE UTILITY MODEL

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Embodiment: A controllable black tea drying machine, such as Figure 1 - Figure 5 As shown, it includes a horizontally placed insulation cylinder 1, with a support frame 101 installed at the bottom of the insulation cylinder 1 for support. A rotatable drying cylinder 5 is installed inside the insulation cylinder 1. The outer side of the drying cylinder 5 is symmetrically provided with connecting channels 501 corresponding to the feeding mechanism and the discharge mechanism above and below. The outer surface of the drying cylinder 5 is tightly fitted with the inner wall surface of the insulation cylinder 1. A crossbar 502 is connected to the inner center axis of the drying cylinder 5. Two sets of extrusion plate assemblies are arranged between the two ends of the crossbar 502. Each set of extrusion plate assemblies includes three sets of telescopic rods 6 surrounding the crossbar 502. The other ends of the two telescopic rods 6 corresponding to the two sets of extrusion plate assemblies are connected to an arc-shaped pressing plate body 601. Each pressing plate body 601 is a high-temperature resistant arc-shaped plate. The two sets of telescopic rods 6 corresponding to the horizontal direction on the connecting channel 501 reciprocate synchronously to drive the pressing plate body 601 to push back and forth between the cross bar 502 and the inner wall of the drying cylinder 5, squeezing the black tea against the inner wall of the drying cylinder 5 in a cyclic reciprocating manner to accelerate the drying effect.

[0028] In this embodiment, the insulating cylinder 1 and the drying cylinder 5 are both hollowed out on the same side near the cover assembly. The cover assembly includes a sealing circular cover 3 that fits over the outside of the insulating cylinder 1. Multiple sets of fixing bolts 301 are threadedly connected to the edges of the sealing circular cover 3. The fixing bolts 301 threadably connect the sealing circular cover 3 to the outside of the insulating cylinder 1. By removing the cover assembly, the interiors of the insulating cylinder 1 and the drying cylinder 5 can be directly opened, making it easier to clean the interior of the drying cylinder 5 during routine maintenance and preventing residue from being trapped inside the drying cylinder 5 and making it difficult to clean.

[0029] In the embodiment, the feeding mechanism comprises a feeding pipe 102 outside the heat insulation cylinder 1, and a sealing plate 103 is movably connected to the top opening of the feeding pipe 102 through a hinge. By providing the closable feeding mechanism, when the black tea in the heat insulation cylinder 1 is being dried and tumbled, the feeding mechanism is closed in cooperation with the discharging mechanism to lock the temperature in the drying cylinder 5, so that the tea in the drying cylinder 5 can be dried in a constant temperature environment. The discharging mechanism comprises the sealing plate 103 connected to the outside of the heat insulation cylinder 1 below the feeding mechanism, and a valve is installed outside the sealing plate 103.

[0030] In the embodiment, the motor device comprises a support frame 2 corresponding to the front and back of the support frame 1, and a motor body 201 is installed outside the support frame 2. The output shaft of the motor body 201 extends transversely through the inside of the heat insulation cylinder 1, and the output end of the motor body 201 is connected to the center point of the adjacent end of the drying cylinder 5. The motor device drives the drying cylinder 5 to rotate in the heat insulation cylinder 1, so that the black tea in the drying cylinder 5 is tumbled to ensure that the black tea in the drying cylinder 5 is fully dried, and the tumbled black tea is fully contacted with high temperature to accelerate the drying of the black tea.

[0031] The working principle and use process of the utility model are as follows: first, open the sealing plate 103 at the feeding pipe 102, put the black tea to be dried into the drying cylinder 5 from the feeding pipe 102, and then close the sealing plate 103. Start the motor body 201, and the motor body 201 drives the drying cylinder 5 to rotate in the heat insulation cylinder 1, so that the black tea is tumbled in the drying cylinder 5. At the same time, the heating device 4 heats the inside of the drying cylinder 5. In the drying process, the telescopic rod 6 on the connecting channel 501 drives the pressing plate body 601 to reciprocate, so that the black tea is reciprocally extruded between the inside wall of the drying cylinder 5 to accelerate the drying. When the drying is completed, open the valve of the discharging mechanism to discharge the dried black tea from the sealing plate 103. During daily maintenance, the fixing bolt 301 can be unscrewed, and the sealing circular cover plate 3 can be removed for cleaning the inside of the drying cylinder 5.

[0032] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the utility model.
