Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a drying equipment for rice processing. Background Technology

[0002] In the rice processing industry, rice needs to be dried to prevent it from becoming moldy and to facilitate subsequent processing. The most common drying method is electric heating drying, which is combined with a stirring structure to stir the rice during the drying process.

[0003] Drying equipment typically heats the drying tank to dry the rice inside, making it difficult to preheat the rice before it enters, thus affecting the efficiency of the drying equipment. Rice often contains impurities or debris, which are difficult for general drying equipment to filter and sieve, thus reducing the quality of the rice after drying. The heating structure of the drying equipment is usually directly fixed inside the external drying unit, making disassembly and maintenance cumbersome and affecting the convenience of maintenance. Utility Model Content

[0007] Preferably, heating wires are installed on both sides inside the heating outer canister, the input end of the heating wires is electrically connected to the output end of the control panel, the heating wires are located on the outside of the drying inner canister, and a temperature monitor is installed inside the heating outer canister, the input end of the temperature monitor is electrically connected to the output end of the control panel.

[0008] Preferably, a feeding assembly is fixed at the top of the heating outer tank, and a heat-conducting pipe is fixed at the bottom of the feeding assembly. One end of the heat-conducting pipe passes through the heating outer tank and extends into the interior of the heating outer tank.

[0009] Preferably, the feeding assembly has a heating shell, a feeding channel and a cover plate inside. The heating shell is fixed to the surface of the heating outer tank by a support frame. The heating shell has an inclined structure and is connected to the heating outer tank and the heat conduction pipe respectively.

[0010] Preferably, the heating shell has a feeding channel fixed inside, the feeding channel is connected to the heating outer tank, and the surface of the feeding channel is covered with a cover plate, one side of which is rotatably connected to the feeding channel.

[0011] Preferably, a slot is provided circumferentially at the top of the inner drying tank, and a locking block is fixed at the top of the inner heating tank, with the locking block and the slot engaging with each other.

[0012] Preferably, a fixing ring is fixed at the bottom of the outer side of the inner drying tank. The fixing ring is inserted into and cooperates with the outer heating tank. The surface of the outer heating tank is provided with threaded holes along the circumference. The surface of the fixing ring is threaded with fastening bolts. When the locking block is engaged with the locking slot, the fastening bolts are threadedly engaged with the threaded holes.

[0013] Preferably, a screen is fixed at the bottom of the inner drying tank, the screen is located below the stirring rod, and the screen has an inclined structure.

[0014] Preferably, a slag discharge pipe is fixed to the bottom of the drying inner tank, and a rice discharge pipe is fixed to one side of the drying inner tank. One end of the rice discharge pipe passes through the drying inner tank and extends to one side of the screen. A one-way valve is installed on the surface of both the rice discharge pipe and the slag discharge pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the drying equipment for rice processing not only reduces the humidity of rice when it enters the drying tank, but also improves the working efficiency of the drying equipment, improves the quality of rice when the drying equipment is used, and improves the convenience of the drying equipment during maintenance.

[0016] By incorporating a preheating feeding mechanism, some of the hot air from the outer heating tank can be transferred to the inner heating shell via a heat-conducting pipe to heat the feeding channel. Then, the cover is opened, and the rice to be dried is poured into the feeding channel for preheating. Simultaneously, the inclined structure of the feeding channel slows down the falling speed of the rice, increasing the preheating time. Subsequently, the rice falls along the feeding channel into the inner drying tank, thus realizing the preheating function of the rice feeding in the drying equipment, reducing the humidity of the rice when it enters the inner drying tank, and thereby improving the working efficiency of the drying equipment.

[0017] With a screening mechanism, rice can be screened by the screen, allowing impurities and debris in the rice to pass through the screen and fall to the bottom of the drying tank. After the drying equipment is used, the one-way valve can be opened to allow the debris to be discharged through the slag discharge pipe and the rice to be discharged through the rice discharge pipe, thus realizing the screening function of the drying equipment and improving the quality of the rice when the drying equipment is used.

[0018] With a detachable assembly / disassembly mechanism, the heating outer tank is fitted onto the outside of the drying inner tank, allowing the bottom of the heating outer tank to insert into the fixing ring. The heating outer tank is then rotated, causing the locking block to engage with the locking groove. When the locking block engages with the groove, the fastening bolt and threaded hole are threaded together. The fastening bolt can then be rotated to tighten the threaded connection, thus securing the fixing ring to the heating outer tank. Since the drying mechanism is mounted on the surface of the heating outer tank, maintenance can be performed by simply separating the drying inner tank from the heating outer tank to inspect the electrical components inside the heating outer tank. This detachable assembly / disassembly function of the drying equipment significantly improves the convenience of maintenance. Attached Figure Description

[0025] The structure of the drying equipment for rice processing provided by this utility model is as follows: Figure 1 and Figure 2As shown, the system includes an inner drying tank 1, on the surface of which a control panel 11 is mounted. The control panel 11 contains an embedded lithium battery and a processor. The processor includes an amplifier tube, a protection resistor Rm, a filter, an A / D converter, and a microcontroller. A sensor and the protection resistor Rm are connected in parallel with the amplifier tube and then in series with the filter. The signal is converted by the A / D converter and sent to the microcontroller. A display screen receives the processing signals from the microcontroller. A heating outer tank 12 is located outside the inner drying tank 1. A drying mechanism 2 is located between the inner drying tank 1 and the heating outer tank 12. The drying mechanism 2 consists of a stirring rod 21, a heating wire 22, a temperature monitor 23, and a drive motor 24. The stirring rod 21 is rotatably connected to the surface of the heating outer tank 12. A drive motor 24 is mounted on the surface of the inner drying tank 1. The drive motor 24 can be of the JO series. The input end of the drive motor 24 is electrically connected to the output end of the control panel 11. The output end of the drive motor 24 is fixed to a rotating shaft through a coupling. One end of the rotating shaft is fixedly connected to one end of the stirring rod 21. Heating wires 22 are installed on both sides inside the outer heating tank 12. The heating wires 22 can be of the CY series. The input end of the heating wires 22 is electrically connected to the output end of the control panel 11. The heating wires 22 are located on the outside of the inner drying tank 1. A temperature monitor 23 is installed inside the outer heating tank 12. The temperature monitor 23 can be of the SDN series. The input end of the temperature monitor 23 is electrically connected to the output end of the control panel 11.

[0026] Furthermore, such as Figure 4 As shown, a feeding preheating mechanism 3 is provided at the top of the heating outer tank 12. The feeding preheating mechanism 3 includes a feeding component 31 and a heat-conducting pipe 32 inside. The feeding component 31 is fixed at the top of the heating outer tank 12, and the heat-conducting pipe 32 is fixed at the bottom of the feeding component 31. One end of the heat-conducting pipe 32 passes through the heating outer tank 12 and extends into the interior of the heating outer tank 12. The feeding component 31 is provided with a heating shell 311, a feeding channel 312 and a cover plate 313 inside. The heating shell 311 is fixed to the surface of the heating outer tank 12 by a support frame. The heating shell 311 has an inclined structure. The heating shell 311 is connected to the heating outer tank 12 and the heat-conducting pipe 32 respectively. The feeding channel 312 is fixed inside the heating shell 311 and is connected to the heating outer tank 12. The surface of the feeding channel 312 is covered with a cover plate 313, and one side of the cover plate 313 is rotatably connected to the feeding channel 312.

[0027] In use, under the action of the heat conduction pipe 32, some of the hot air inside the heating outer tank 12 can be conducted to the heating outer shell 311 to heat the feeding channel 312. Then, the cover plate 313 is opened and the rice to be dried is poured into the feeding channel 312 to preheat the rice. At the same time, since the feeding channel 312 has an inclined structure, the falling speed of the rice can be slowed down, increasing the preheating time of the rice. Then, the rice falls into the drying inner tank 1 along the feeding channel 312 to realize the feeding preheating function of the drying equipment for rice.

[0028] Furthermore, such as Figure 2 and Figure 3 As shown, the inner drying tank 1 and the outer heating tank 12 are connected and disassembled by a split-type disassembly and assembly mechanism 4. The split-type disassembly and assembly mechanism 4 consists of a fixing ring 41, a slot 42, a locking block 43, a fastening bolt 44, and a threaded hole 45. The top position of the inner drying tank 1 is provided with a slot 42 along the circumference. The top position of the inner heating tank 12 is fixed with a locking block 43. The locking block 43 and the slot 42 are engaged with each other. The bottom position of the outer side of the inner drying tank 1 is fixed with a fixing ring 41. The fixing ring 41 and the outer heating tank 12 are inserted into each other. The surface of the outer heating tank 12 is provided with a threaded hole 45 along the circumference. The surface of the fixing ring 41 is threaded with a fastening bolt 44. When the locking block 43 and the slot 42 are engaged, the fastening bolt 44 and the threaded hole 45 are threadedly engaged.

[0029] In use, the heating outer canister 12 is fitted onto the outside of the drying inner canister 1, so that the bottom of the heating outer canister 12 is inserted into the inside of the fixing ring 41. Then, the heating outer canister 12 is rotated so that the locking block 43 is locked into the inside of the locking groove 42. When the locking block 43 is engaged with the locking groove 42, the fastening bolt 44 is threaded into the threaded hole 45. At this time, the fastening bolt 44 can be rotated to tighten the fastening bolt 44 into the threaded hole 45, thereby fixing the fixing ring 41 and the heating outer canister 12. Since the drying mechanism 2 is installed on the surface of the heating outer canister 12, if maintenance is required, only the drying inner canister 1 and the heating outer canister 12 need to be disassembled to inspect the electrical components inside the heating outer canister 12, so as to realize the split-type disassembly and assembly function of the drying equipment.

[0030] Furthermore, such as Figure 2 As shown, a screening mechanism 5 is provided at the bottom of the drying inner tank 1. The screening mechanism 5 includes a rice discharge pipe 51, a screen 52, a one-way valve 53, and a slag discharge pipe 54. The screen 52 is fixed at the bottom of the drying inner tank 1 and is located below the stirring rod 21. The screen 52 has an inclined structure. The slag discharge pipe 54 is fixed at the bottom of the drying inner tank 1, and the rice discharge pipe 51 is fixed on one side of the drying inner tank 1. One end of the rice discharge pipe 51 passes through the drying inner tank 1 and extends to one side of the screen 52. One-way valves 53 are installed on the surfaces of both the rice discharge pipe 51 and the slag discharge pipe 54.

[0031] During use, the rice can be sieved by the screen 52, so that the impurities and dregs contained in the rice can pass through the screen 52 and fall to the bottom of the drying inner tank 1. After the drying equipment is used, the one-way valve 53 can be opened to allow the dregs to be discharged through the slag discharge pipe 54 and the rice to be discharged through the rice discharge pipe 51, so as to realize the sieving function of the drying equipment for rice.

[0032] Working principle: In use, first, the heating outer canister 12 is fitted onto the outside of the drying inner canister 1, so that the bottom of the heating outer canister 12 is inserted into the inside of the fixing ring 41. Then, the heating outer canister 12 is rotated so that the locking block 43 is locked into the inside of the locking groove 42. When the locking block 43 is engaged with the locking groove 42, the fastening bolt 44 is threadedly engaged with the threaded hole 45. At this time, the fastening bolt 44 can be rotated to tighten the fastening bolt 44 with the threaded hole 45, thereby fixing the fixing ring 41 and the heating outer canister 12. Since the drying mechanism 2 is installed on the surface of the heating outer canister 12, if maintenance is required, only the drying inner canister 1 and the heating outer canister 12 need to be disassembled to inspect the electrical components inside the heating outer canister 12, so as to realize the split disassembly and assembly function of the drying equipment, thereby improving the convenience of maintenance of the drying equipment.

[0033] The control panel 11 is operated to control the heating wire 22 and temperature monitor 23. The heating wire 22 heats the surface of the inner drying tank 1, and the temperature monitor 23 monitors the temperature. At the same time, the heat pipe 32 can conduct some of the hot air inside the outer heating tank 12 to the heating shell 311 to heat the feeding channel 312. Then, the cover 313 is opened, and the rice to be dried is poured into the feeding channel 312 for preheating. Since the feeding channel 312 is inclined, the falling speed of the rice is slowed down, increasing the preheating time. The rice then falls into the inner drying tank 1 along the feeding channel 312, thus realizing the preheating function of the rice feeding of the drying equipment, reducing the humidity of the rice when it enters the inner drying tank 1, thereby improving the working efficiency of the drying equipment.

[0034] Then, operate the control panel 11 to control the drive motor 24 to work. Under the action of the drive motor 24, the stirring rod 21 is rotated to stir the rice so that the rice is heated evenly. At the same time, the rice can be sieved by the screen 52, so that the impurities and debris contained in the rice can pass through the screen 52 and fall to the bottom of the drying inner tank 1. After the drying equipment is used, the one-way valve 53 can be opened to discharge the debris through the slag discharge pipe 54 and the rice through the rice discharge pipe 51, so as to realize the sieving function of the drying equipment on the rice, thereby improving the quality of the rice when the drying equipment is used, and finally completing the use of the drying equipment.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
