Description

Technical Field

[0001] The utility model relates to the technical field of tea drying and dehumidification, in particular to a drying and dehumidification device used for white tea production. Background Art

[0002] The production process of white tea is relatively simple. It does not go through processes such as frying and rolling, but usually only goes through steps such as withering and drying, which helps to retain the natural ingredients and nutrients in the tea. First of all, white tea has a long history and has a profound cultural heritage and tradition in China. Its origin can be traced back to ancient times. After a long period of development and inheritance, it has formed a unique production process and tasting method. The quality characteristics of white tea are also closely related to its production process. During the withering process, the moisture in the tea leaves gradually dissipates, and a series of chemical changes occur at the same time, which helps to form the unique aroma, taste and color of white tea. The drying step further removes the moisture in the tea leaves to make them reach an appropriate water content, which is convenient for storage and brewing.

[0003] Many traditional drying and dehumidification equipment use desiccants that are fixed inside the equipment, or the replacement process is extremely cumbersome and complicated. As the equipment is used for a long time, the desiccant will gradually absorb saturated moisture, and its dehumidification capacity will decrease significantly. When the desiccant loses its effectiveness, the humidity control in the equipment will be unstable, which may lead to uneven moisture content of the tea leaves during the drying process.

Compared with the fixed drying method, this rotating design avoids local overheating or uneven drying of the tea leaves due to being in the same position for a long time. The rotating drying part drives the tea leaves to move, so that the surrounding air forms a more effective circulation, and the hot air can more fully contact the tea leaves, taking away the moisture evaporated from the surface of the tea leaves, thereby accelerating the drying process.

[0015] (2) The utility model can increase the temperature inside the device through the coordination between the air inlet box, screen, fan motor, fan, heating plate, metal rod, heating resistor wire, screen plate, pull armrest and mounting block 2, so that the moisture in the tea leaves evaporates into water vapor faster. As the temperature rises, the movement speed of water molecules accelerates, and the ability to diffuse from the inside of the tea leaves to the surface and the surrounding air is enhanced. However, during long-term use, the dehumidification capacity of the desiccant will gradually decrease as the amount of moisture adsorbed increases. The replaceable desiccant design allows for timely replacement of the desiccant after it reaches saturation, ensuring that the device always maintains high dehumidification efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1

[0024] The preferred embodiment of the drying and dehumidifying equipment for white tea production provided by the utility model is as follows Figure 1-4 As shown: A drying and dehumidifying device for white tea production, including a support plate 1, a rotary drying section 3, and a heating, drying and dehumidifying section 4. A support leg 2 is fixedly installed at the bottom of the support plate 1, and a support pad is fixedly installed at the other end of the support leg 2; the rotary drying section 3 is arranged on the top of the support plate 1, and the heating, drying and dehumidifying section 4 is arranged on the top of the support plate 1.

[0025] The rotary drying section 3 specifically includes: a drying box 3112, on the top of which the support plate 1 is fixedly installed; a box door is provided on the drying box 3112, and the outer walls of the drying box 3112 are respectively provided with air inlet and exhaust vents, and an observation window is provided on the box door. Support blocks 316 are fixedly installed inside the drying box 3112, and a roller 317 is rotatably connected between the support blocks 316. A motor fixing bracket 311 is fixedly installed on the outer wall of the other side of the drying box 3112, and a motor 312 is provided inside the motor fixing bracket 311.

[0026] The output end of the motor 312 is fixedly connected to a rotating rod 313, the other end of the rotating rod 313 is movable through the outer wall of the drying box 3112 and extends to the interior of the drying box 3112, the other end of the rotating rod 313 is fixedly connected to a rotating block 314, and the outer wall on the other side of the rotating block 314 is fixedly connected to a drying drum 315.

[0027] The drying drum 315 has through holes equidistantly arranged on its circumference. The drying drum 315 is arranged between the outer walls of the drum 317. A threaded feed port is provided on the outer wall of the drying drum 315. The internal thread of the threaded feed port is connected to a threaded block 318. A handle 319 is fixedly installed on the outer wall of the threaded block 318. Tooth blocks 3111 are fixedly installed on the inner wall of the drum 317 at equidistant intervals.

[0028] In the process of this embodiment, the door of the drying box 3112 is opened, and the threaded block 318 is driven to rotate by manually turning the handle 319. The threaded block 318 is removed from the drying drum 315 as it rotates, and the white tea to be dried is put into the interior of the drying drum 315 through the threaded feed port. The threaded block 318 is then driven by the handle 319 to rotate in the threaded feed port in the opposite direction to seal the threaded feed port. The door of the drying box is then closed and the motor 312 and the heating resistor 417 are started respectively.

Compared with the fixed drying method, this rotating design avoids local overheating or uneven drying of the tea leaves due to staying in the same position for a long time. The rotating drying part drives the tea leaves to move, so that the surrounding air forms a more effective circulation, and the hot air can come into contact with the tea leaves more fully, taking away the moisture evaporated from the surface of the tea leaves, and accelerating the drying process.

[0029] Example 2

[0030] On the basis of Example 1, the present invention provides a preferred embodiment of a drying and dehumidifying device for white tea production. Figure 1-4 As shown: the heating, drying and dehumidifying part 4 specifically includes: an air inlet box 411, which is equidistantly arranged on the outer wall of the drying box 3112; a heating plate 415, which is fixedly installed on the inner wall of the drying box 3112; an exhaust fan 419, which is arranged on the outer wall of the drying box 3112; a mounting block 418, which is fixedly installed on the inner wall of the drying box 3112; and a mounting block 4116, which is fixedly installed on the inner wall of the drying box 3112.

[0031] A screen 412 is fixedly mounted on the inner wall of the air inlet box 411 , a fan motor 413 is fixedly mounted on the outer wall of the screen 412 , and a fan 414 is fixedly connected to the output end of the fan motor 413 .

[0032] The air inlet box 411 is connected to the drying box 3112 through the air inlet port. Ventilation mesh holes are equidistantly provided on the heating plate 415. A heating cavity is provided inside the heating plate 415. Metal rods 416 are fixedly installed equidistantly between the inner walls of the heating cavity. A heating resistance wire 417 is sleeved on the outer wall of the metal rod 416.

[0033] A rectangular mounting plate 4111 is fixedly connected between mounting block 1 418 and mounting block 2 4116. Both mounting block 1 418 and mounting block 2 4116 are provided with slide grooves, and slider 1 4112 and slider 2 4113 are slidingly connected inside the slide grooves respectively. A screen plate 4114 is fixedly connected equidistantly between slider 1 4112 and slider 2 4113. A pulling handrail 4115 is fixedly installed on the outer wall of slider 2 4113. A desiccant is provided on the screen plate 4114, and the exhaust fan 419 is connected to the drying box 3112 through the exhaust vent.

[0034] In the process of this embodiment, when the temperature rises to a suitable range, the fan motor 413 and the exhaust fan 419 are started respectively, and the fan motor 413 drives the fan 414 to rotate. The airflow generated by the rotation of the fan 414 will turn into hot air after passing through the ventilation mesh, and then dry and heat the white tea through the through holes on the drying drum 315. The water vapor generated by the drying and heating of the white tea is extracted to the outside of the drying box 3112 through the rear exhaust fan 419, and the desiccant between the screen plates 4114 will absorb excess water vapor in the air, so that the internal environment of the drying box 3112 remains dry. When the drying drum 315 needs to be replaced, the hot air will be turned into hot air. When replacing the desiccant, one only needs to pull the handrail 4115 to drive the slider 1 4112 and the slider 2 4113 to be drawn out in the slide slot. This can increase the temperature inside the device and make the moisture in the tea leaves evaporate into water vapor faster. As the temperature rises, the movement speed of water molecules accelerates, and their ability to diffuse from the inside of the tea leaves to the surface and the surrounding air is enhanced. However, during long-term use, the dehumidification capacity of the desiccant will gradually decrease as the amount of moisture absorbed increases. The replaceable desiccant design allows for timely replacement of the desiccant after it reaches saturation, ensuring that the device always maintains high dehumidification efficiency.

[0035] Working principle: first open the door of the drying box 3112, then manually turn the handle 319 to drive the threaded block 318 to rotate, and the threaded block 318 will be removed from the drying drum 315 as it rotates, and then put the white tea to be dried into the interior of the drying drum 315 through the threaded feed port, and then use the handle 319 to drive the threaded block 318 to rotate in the threaded feed port in the opposite direction to seal the threaded feed port, and then close the door and start the motor 312 and the heating resistor 417 respectively. When the motor 312 is started, it drives the drying drum 315 to rotate in the drying box 3112, and when the drying drum 315 rotates, it drives the tooth block 3111 on the inner wall of the drying drum 315 to comb and disperse the white tea, and when the heating resistor 417 is started, The heating plate is preheated. When the temperature rises to a suitable range, the fan motor 413 and the exhaust fan 419 are started respectively. The fan motor 413 drives the fan 414 to rotate. The airflow generated by the rotation of the fan 414 will turn into hot air after passing through the ventilation mesh, and then the white tea is dried and heated through the through holes on the drying drum 315. The water vapor generated by the drying and heating of the white tea is extracted to the outside of the drying box 3112 through the rear exhaust fan 419, and the desiccant between the screen plates 4114 will absorb excess water vapor in the air, so that the internal environment of the drying box 3112 remains dry. When the desiccant needs to be replaced, the desiccant can be replaced by pulling the handrail 4115 to drive the slider 1 4112 and the slider 2 4113 to be pulled out in the slide slot.
