A corn cob drying device

Abstract

This utility model discloses a corn cob drying device, including a base plate. An annular mesh plate for the flow of waste heat air is fixedly connected inside the mounting plate. A connecting pipe connecting the bottom of the central hood to the dehumidification rotor processing area is installed. Through the design of the protective cover, annular mesh plate, and supporting mesh plate, this utility model uses the protective cover to seal the corn cob during drying. After drying, the hot air passes through the annular mesh plate and is dehumidified by the dehumidification rotor inside the dehumidification rotor frame. The dehumidified hot air is then transported through the supporting mesh plate on the mesh plate frame to the corn cobs stored in the pre-storage seat for pre-drying treatment. This allows for the reuse of waste heat, significantly reducing energy waste and lowering production costs incurred by enterprises due to repeated heating. Furthermore, the pre-drying step shortens the subsequent formal drying time and improves overall drying efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A corn cob drying device includes a base plate 1, a pre-storage base 4 for pre-storing corn cobs is fixedly installed on the top of the base plate 1, a base 2 and a mesh frame 17 are fixedly installed on the inner bottom of the pre-storage base 4, the mesh frame 17 is connected to and fixed on the surface of the base 2, and a support mesh plate 18 is fixedly installed on the top of the mesh frame 17.

[0028] A mounting plate is fixedly installed on the top of the base 2. A protective cover 12 for sealing the corn ears during drying is provided on the top of the mounting plate. An annular mesh plate 13 for the flow of residual heat air is fixedly connected inside the mounting plate.

[0029] The inner wall of the base 2 is fixedly installed with a central cover 16 and a dehumidifying wheel frame 15 with a dehumidifying wheel from top to bottom. The bottom of the central cover 16 is connected to the dehumidifying wheel processing area by a connecting pipe 22.

[0030] It should be noted that the pre-storage seat 4 is used to store pre-dried corn ears and to collect the dried corn ears when they are discharged. The centralized cover 16, together with the connecting pipe 22, is used to guide the air discharged after the corn ears are dried, so that the dehumidification wheel can dehumidify the moisture in the hot air after the corn ears are dried, reduce the moisture content in the air, and prevent it from affecting the subsequent pre-drying of the corn ears in the pre-storage seat 4.

[0031] The dehumidifying wheel and dehumidifying wheel frame 15 are existing technologies, and their internal working principle and operation process will not be described in detail here.

[0032] In an optional embodiment: such as Figure 2 As shown, a columnar base 3 is fixedly installed on the top of the mounting plate, and a first columnar mesh tube 6 for preventing corn ears from entering is fixedly connected inside the columnar base 3.

[0033] It should be noted that the first columnar mesh tube 6 serves to block the corn ears and prevent them from entering the columnar seat 3.

[0034] In an optional embodiment: such as Figure 1 and Figure 2 As shown, a cylinder 5 is fixedly installed on the top of the cylindrical base 3, and a lifting plate 20 is fixedly installed on the telescopic end of the cylinder 5. The lifting plate 20 is sleeved on the surface of the cylindrical base 3. A second cylindrical mesh tube 11 is installed at the bottom of the lifting plate 20 through a quick-release mechanism. A protective cover 12 is fixedly connected to the outside of the second cylindrical mesh tube 11. The bottom of the second cylindrical mesh tube 11 is in contact with the top of the mounting plate.

[0035] The channel between the first columnar mesh tube 6 and the second columnar mesh tube 11 is set as a placement channel for corn ears, used for storing corn ears during drying. The channel between the second columnar mesh tube 11 and the protective cover 12 is set as an air circulation channel, used for air circulation after the corn ears are dried with hot air. The lifting plate 20, the protective cover 12 and the second columnar mesh tube 11 can be raised and lowered by the cylinder 5, which makes it easy to pour the corn ears into the placement channel or to discharge the dried corn ears from the placement channel.

[0036] It should be noted that a sealing gasket 19 is affixed to the bottom of the lifting plate 20. The sealing gasket 19 is used to seal the bottom of the lifting plate 20 with the second columnar mesh tube 11 and the top of the protective cover 12, thereby reducing the leakage of hot air.

[0037] Additionally, an inclined seat 14 is fixedly installed on the top of the mounting plate. The inclined seat 14 is located in the placement channel and can facilitate the discharge of corn ears in the placement channel.

[0038] In an optional embodiment: such as Figure 2 , Figure 3 and Figure 5 As shown, the quick-release mechanism includes a connecting block 23, a guide rail 24, a slide 25, a connecting rod 26, and a support base 27. The connecting block 23 is fixedly connected to the inner wall of the second cylindrical mesh tube 11 in a circular array. The guide rail 24 and the support base 27 are both fixedly installed on the top of the lifting plate 20 in a circular array. The side of the support base 27 contacts the side of the connecting block 23. The slide 25 is slidably installed on the top of the guide rail 24. The connecting rod 26 is fixedly installed on the top of the slide 25 and is inserted into the connecting block 23 and the support base 27.

[0039] It should be noted that the connecting block 23, guide rail 24, slide 25, plug rod 26 and support base 27 cooperate to install and disassemble the second columnar mesh tube 11, improving the convenience of installing and disassembling the second columnar mesh tube 11 and the protective cover 12.

[0040] In an optional embodiment: such as Figure 5 As shown, magnets 8 are fixedly installed on the inner wall of the support base 27 and the top of the plug rod 26, and the magnets 8 on the inner wall of the support base 27 and the magnets 8 on the top of the plug rod 26 attract each other.

[0041] It should be noted that the magnet 8 is used to fix the plug rod 26, which can improve the stability of the plug rod 26 installed in the connecting block 23 and the support base 27.

[0042] In an optional embodiment: such as Figure 2 and Figure 4 As shown, a heating cylinder 9 is fixedly connected to the inner bottom of the cylindrical base 3, and the top of the heating cylinder 9 is fixedly connected to the inner top of the cylindrical base 3. A blower 7 for supplying air into the heating cylinder 9 is fixedly installed on the top of the cylindrical base 3, and the air outlet of the blower 7 is connected to the heating cylinder 9 through a pipe.

[0043] It should be noted that air can be delivered into the heating cylinder 9 by using the blower 7 in conjunction with the pipeline.

[0044] In an optional embodiment: such as Figure 4 As shown, an electric heating wire 10 for heating the air supplied by the blower 7 is fixedly installed inside the heating cylinder 9.

[0045] It should be noted that the electric heating wire 10 is used to heat the conveyed air, and the heated air can be evenly introduced into the first cylindrical mesh tube 6 through the heating cylinder 9.

[0046] In an optional embodiment: such as Figures 1-3 As shown, the inner wall of the second columnar mesh tube 11 is symmetrically and fixedly connected with two sets of guide rods 21, which are movably inserted into the inside of the lifting plate 20.

[0047] It should be noted that the guide rod 21 serves to position the second cylindrical mesh tube 11, preventing the second cylindrical mesh tube 11 from shifting position, and making it easier for the connecting block 23 to be smoothly inserted into the lifting plate 20.

[0048] The usage process of this utility model is as follows: When drying corn ears, the corn ears to be dried are poured into the placement channel. The cylinder 5 is started, and the telescopic end of the cylinder 5 pushes the lifting plate 20 so that the lifting plate 20 can be fitted onto the columnar seat 3. At the same time, the sealing gasket 19 at the bottom of the lifting plate 20 can press the top of the second columnar mesh tube 11 and the protective cover 12. By sliding the slide block 25, the slide block 25 drives the insertion rod 26 to move, so that the insertion rod 26 is inserted into the connecting block 23 and the support seat 27. The second columnar mesh tube 11 and the protective cover 12 are fixed to the bottom of the lifting plate 20 by the insertion rod 26 and the connecting block 23.

[0049] In addition, corn ears that need to be pre-dried are placed in the pre-storage seat 4 in advance. The electric heating wire 10 and the blower 7 are started. The blower 7 draws in the outside air and transports it to the inside of the heating cylinder 9 through the pipeline. The electric heating wire 10 heats the transported air. The heated air can pass through the heating cylinder 9 and enter the inside of the cylindrical seat 3. Then it passes through the first cylindrical mesh tube 6 and through the placement channel to dry the corn ears inside the placement channel with hot air.

[0050] After the corn ears have been dried with hot air, the hot air passes through the second columnar mesh tube 11 and enters the air circulation channel. After passing through the annular mesh plate 13, the hot air enters the base 2. The hot air is concentrated by the central hood 16 and the connecting pipe 22 and conveyed to the dehumidifying rotary frame 15. The dehumidifying wheel inside the dehumidifying rotary frame 15 dehumidifies the moisture in the hot air. The dehumidified air can enter the mesh plate frame 17 and then be conveyed by the supporting mesh plate 18 to the corn ears stored in the pre-storage seat 4 for pre-drying treatment. This allows for the reuse of waste heat. Through the waste heat reuse process, energy waste can be greatly reduced, the production costs caused by repeated heating can be reduced, and the pre-drying step can shorten the subsequent formal drying time and improve the overall drying efficiency.

[0051] Before the corn ears inside the placement channel are completely dried, the pre-dried corn ears inside the pre-storage seat 4 are loaded. After the corn ears inside the placement channel are dried, cylinder 5 is activated. The telescopic rod of cylinder 5 retracts, causing the lifting plate 20, the second cylindrical mesh tube 11, and the protective cover 12 to move upward, allowing the corn ears inside the placement channel to fall into the pre-storage seat 4 for collection. After the corn ears are collected, cylinder 5 is activated again. The telescopic end of cylinder 5 pushes the lifting plate 20, causing the second cylindrical mesh tube 11 and the protective cover 12 to move upward. The protective cover 12 moves, allowing the second cylindrical mesh tube 11 and the protective cover 12 to be placed on top of the mounting plate. By sliding the slide block 25, the slide block 25 drives the plug rod 26 out of the connecting block 23 and the support base 27. Then, the cylinder 5 is activated, causing the cylinder 5 to drive the lifting plate 20 away from the second cylindrical mesh tube 11 and the protective cover 12. At this time, the pre-dried corn ears can be poured into the placement channel, and the corn ears that need to be pre-dried can be poured into the pre-storage seat 4. Through the above steps, the corn ears can be dried again.

[0052] The control method in this application is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so the control method and circuit connection will not be explained in detail. The device is powered by a built-in power supply or an external power supply.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
