Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a product drying equipment. Background Art

[0002] Drying refers to the process of removing moisture from food after it is heated and evaporated in hot air. Food drying is one of the main technologies in food storage and processing. Most of the moisture in food can be removed through drying technology to reduce water activity, inhibit the growth and reproduction of microorganisms, and extend the storage period of food. There are two aspects in the drying process: one is that water molecules in the food migrate from the inside to the surface in contact with dry hot air. When the water molecules reach the surface, according to the vapor pressure difference between the surface and the air, the water molecules immediately transfer and diffuse into the air - moisture transfer; the other is that the heat in the hot air is transferred from the air to the surface of the food, and then from the surface to the inside of the food - heat transfer. Therefore, the food drying process involves both mass (moisture) transfer and heat transfer, that is, wet heat transfer.

[0003] The Chinese utility model patent with the authorization announcement number "CN216011565U" is specifically "a product outer surface drying device". Its specification states in its specific implementation mode that "the air inlet of the present invention corresponds to the heating rod, and the air outlet is at the bottom of the ventilation drying box, so as to realize the rapid and stable circulation of hot air, and achieve the purpose of drying by combining with the vibration device";

[0004] The above-mentioned device is provided with an air inlet on the drying box for the gas circulation in the inner cavity of the drying box, and a heating rod is installed in the drying box. The air entering through the air inlet is heated by the heating rod to increase the air temperature in the drying box, thereby improving the drying effect. Dust and impurities can easily enter the drying box from the air inlet and contaminate the product. Since the drying box is also provided with an air outlet, the air heated by the heating rod will be quickly discharged from the air outlet, resulting in the temperature in the drying box being difficult to increase. Therefore, the drying effect is also effectively improved. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a product drying device, which can effectively solve the problem of poor drying effect of the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The present invention provides a product drying device, comprising a drying tank and a cover plate buckled on the top of the drying tank, a drying chamber is provided in the drying tank, a carrier plate is vibratingly installed in the drying chamber, an air intake and exhaust assembly comprises two air intake and exhaust pipes installed on the outer tube wall of the drying tank and connected with the drying chamber, valves are installed on the air intake and exhaust pipes, a plurality of arc-shaped drying mesh cage assemblies are rotatably installed in the drying chamber below the cover plate, the arc-shaped drying mesh cage assemblies are filled with desiccant, a synchronous rotation assembly comprises an annular member which rotates synchronously with the arc-shaped drying mesh cage assembly and is located at the bottom of the drying chamber, a plurality of fan blades are installed on the top of the annular member.

[0008] Furthermore, the top of the drying tank is provided with an annular cavity, the bottom of the drying cavity is provided with an annular groove for convenient insertion and rotation of the annular member, and the top of the annular member is provided with a plurality of arc-shaped openings for convenient insertion of the bottom of the arc-shaped drying cage assembly.

[0009] Furthermore, an inner ring wall of the annular member is installed with an inner limit ring, an outer ring wall of the annular member is installed with an outer limit ring, and the inner ring wall of the inner limit ring and the outer ring wall of the outer limit ring are both embedded with a plurality of balls rollingly installed in contact with the inner groove wall of the annular groove).

[0010] Furthermore, an annular ring adapted to be inserted into the annular cavity is installed at the bottom end of the cover plate, a motor is installed at the center of the top circle of the cover plate, and the output end of the motor extends through and extends to the bottom of the cover plate and is installed with a rotating disk.

[0011] Furthermore, the arc-shaped drying mesh cage components are inserted in a circular array with equal spacing at the bottom end of the rotating disk, and are rotatably installed in the drying cavity space outside the carrier disk.

[0012] Furthermore, the arc-shaped drying mesh cage assembly comprises an arc-shaped mesh cage and an arc-shaped mesh cover which are plugged into each other, and the desiccant is filled between the arc-shaped mesh cage and the arc-shaped mesh cover.

[0013] Furthermore, a heating resistor plate is installed at the bottom end of the rotating disk, and two handles which are symmetrically distributed in the center are installed on the outer ring wall of the cover plate.

[0014] Furthermore, a vibration motor is installed at the center of the lower bottom of the carrier plate, and a plurality of springs are also installed at the lower bottom of the carrier plate, and connecting seats are installed between the plurality of springs and the bottom of the drying chamber.

[0015] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0016] 1. A cover plate is buckled on the top of the drying tank, and the valves on the inlet and outlet air pipes on the outer ring wall of the drying tank are closed, so that the drying chamber in the drying tank is closed. The temperature in the drying chamber is increased by starting the resistance heating plate, thereby preliminarily improving the drying effect and preventing dust and impurities from entering the drying chamber and contaminating the product;

[0017] 2. Several arc-shaped drying mesh cage components filled with desiccant are installed in a rotating manner in the drying tank. The adsorption effect of the desiccant further improves the drying effect. The rotation of the arc-shaped drying mesh cage components will also drive the rotation of the bottom ring and the fan blades on the top of the ring, thereby accelerating the air circulation in the closed drying chamber, increasing the frequency of contact between the hot air flow and the product surface, and further improving the drying effect.

[0018] 3. After the product is taken out after drying, close the cover again, start the resistance heating plate to increase the temperature in the drying chamber, and drive several arc-shaped drying cage components to rotate at the same time, so that the desiccant in the arc-shaped drying cage components can be desorbed by high temperature, thereby extending the service life and reducing the frequency of desiccant replacement, thereby improving the drying efficiency;

[0019] 4. The arc drying mesh cage assembly consists of an arc mesh cage and an arc mesh cover that are plugged into each other, and is installed in the drying chamber by plugging up and down. With the cover plate removed, the arc drying mesh cage can be directly pulled out from the annular member, and the arc mesh cover can be quickly opened to replace the desiccant in the arc mesh cage, making the loading and unloading of the desiccant more convenient and quick.

[0030] The present invention will be further described below in conjunction with the embodiments.

[0033] Example 2

[0034] Reference Figure 1-2 as well as Figure 5-6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: an annular cavity 12 is provided on the top of the drying tank 1, an annular groove 15 is provided at the bottom of the drying chamber 11 for conveniently inserting and rotating the annular member 16, a plurality of arc-shaped openings 17 are provided at the top of the annular member 16 for conveniently inserting and inserting the bottom of the arc-shaped drying cage assembly 24, an inner limiting ring 19 is installed on the inner ring wall of the annular member 16, an outer limiting ring 110 is installed on the outer ring wall of the annular member 16, a plurality of balls 111 are embedded and rollingly installed on the inner ring wall of the inner limiting ring 19 and the outer ring wall of the outer limiting ring 110, which are in rolling contact with the inner groove wall of the annular groove 15, so as to reduce the wear of the annular member 16 during rotation, an annular ring 21 adapted to be inserted into the annular cavity 12 is installed at the bottom end of the cover plate 2, when the cover plate 2 is buckled onto the top of the drying tank 1, the annular ring 21 is just inserted into the corresponding annular cavity 12, and then the valves 14 on the two inlet and exhaust pipes 13 are closed, so that the drying chamber 11 is isolated from the outside to prevent heat loss.

[0035] The remaining structures are the same as those of Example 1.

[0036] Reference Figure 1-4 as well as Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a motor 22 is installed at the center of the top of the cover plate 2, and the output end of the motor 22 extends through the cover plate 2 and is installed with a rotating disk 23. A plurality of arc-shaped drying mesh cage assemblies 24 are inserted in a circular array at equal intervals at the bottom of the rotating disk 23, and are rotatably installed in the drying chamber 11 space outside the carrier plate 3. The arc-shaped drying mesh cage assembly 24 includes an arc-shaped mesh cage 241 and an arc-shaped mesh cover 242 that are plugged into each other. The desiccant is filled between the arc-shaped mesh cage 241 and the arc-shaped mesh cover 242. Since the arc-shaped mesh cage 241 and the arc-shaped mesh cover 242 are simply plugged into each other, disassembly is very simple. In addition, since the top and bottom of the arc-shaped drying mesh cage assembly 24 are both plug-in mounted, Therefore, during the rotation process, the arc-shaped mesh cage 241 and the arc-shaped mesh cover 242 will not loosen or separate, causing the desiccant to fall out. The rotating arc-shaped drying mesh cage assembly 24 can improve the air circulation in the drying chamber 11 and will not contact the vibrating carrier 3. A heating resistor plate 25 is installed at the bottom end of the rotating disk 23, and two handles 26 with central symmetry are installed on the outer ring wall of the cover plate 2 to facilitate the loading and unloading of the cover plate 2. A vibration motor 31 is installed at the center of the lower bottom of the carrier plate 3, and a plurality of springs 32 are also installed at the lower bottom of the carrier plate 3 to improve the vibration effect of the carrier plate 3. Connecting seats 33 are installed between the plurality of springs 32 and the bottom of the drying chamber 11, and the springs 32 will not have any contact or collision with the annular member 16 during the vibration process.

[0037] The remaining structure is the same as that of Example 2.

[0038] First, place the product to be dried on the carrier plate 3, close the valves 14 on the two inlet and outlet pipes 13, and then buckle the cover plate 2 on the top of the drying tank 1 through the two handles 26, so that the annular ring 21 at the bottom of the cover plate 2 is just inserted into the annular cavity 12 at the top of the drying tank 1, so that the drying cavity 11 is sealed and isolated from the outside;

[0039] Secondly, the power supply of the heating resistor plate 25 is turned on to increase the ambient temperature in the drying chamber 11, and then the motor 22 is started to drive the rotating disk 23 and the plurality of arc-shaped drying mesh cage assemblies 24 to rotate. The desiccant is placed in the arc-shaped mesh cage 241 in advance, and the arc-shaped mesh cover 242 is buckled on the arc-shaped mesh cage 241, so that the arc-shaped desiccant is limited and fixed in the arc-shaped mesh cage 241, and then the top of the arc-shaped drying mesh cage assembly 24 is inserted into the bottom of the rotating disk 23, and the bottom of the arc-shaped drying mesh cage assembly 24 is inserted into the corresponding arc-shaped opening 17, so that the arc-shaped drying mesh cage assembly 24 is forced to be limited and fixed, ensuring that the desiccant will not escape during the rotation process. The relative insertion will also drive the annular member 16 to rotate, thereby driving the plurality of fan blades 18 on the top of the annular member 16 to rotate, so that the high-temperature air in the drying chamber 11 circulates, increasing the contact frequency and contact temperature with the product on the carrier plate 3, thereby improving the drying effect of the product. At the same time, the vibration motor 31 is started to drive the carrier plate 3 to vibrate, which also drives the product to vibrate, so that the water stains on the surface of the product are vibrated away, further improving the drying effect. At the same time, the rotating arc-shaped drying net cage assembly 24 is filled with desiccant, which absorbs the water vapor in the drying chamber 11, so that the drying chamber 11 remains dry, so that the product is in a dry environment, further improving the drying effect.

[0040] Finally, after drying is completed, the cover plate 2 is opened to take out the product, and the cover plate 2 is re-closed, and the heating resistor plate 25 is then turned on to increase the temperature in the drying chamber 11. At the same time, the motor 22 is started to drive the plurality of arc-shaped drying mesh cage assemblies 24 to rotate. The desiccant that absorbs full water vapor will evaporate excess water vapor in the environment of the drying chamber 11, thereby restoring the drying activity of the desiccant. The valve 14 on the inlet and outlet pipes 13 is then opened, and the moisture in the drying chamber 11 is discharged by introducing an external airflow, so as to facilitate the next drying process of the product. The arc-shaped drying mesh cage assembly 24 is regularly taken out from the arc-shaped opening 17 on the annular member 16, and the arc-shaped mesh cover 242 is quickly removed from the surface of the arc-shaped mesh cage 241, so as to facilitate the replacement of completely ineffective desiccant.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
