[0001] The present invention relates to the technical field of drying equipment, in particular to a device integrating with sterilizing, steaming and drying. Background Art

[0002] After harvesting, agricultural products need to be dried. The traditional drying method is to use the sun. This method of drying rice by relying on the sun is becoming less and less suitable for the development of modern rural areas because there are fewer and fewer places to dry rice and the efficiency of drying rice is too low. For this reason, there are some drying equipment dedicated to drying crops on the market. However, these drying equipment either have a simple structure, a large volume, low drying efficiency, and uneven drying, or have a good drying effect but a complex structure and high cost, which cannot be promoted and applied on a large scale. In addition, the existing drying equipment does not have the integrated function of withering, sterilization and drying. Summary of the Invention

[0006] The principle of the technical solution of the present invention is:

[0007] Steam is input into the room through the steam pipe spray device to sterilize and cook the materials, and the indoor pressure, temperature and humidity are controlled and adjusted to meet the production process by two signals of the dehumidification and pressure relief system device and the steam pressure and flow control system device.

[0008] The beneficial effects of this program are:

[0009] 1. The method of introducing steam into the sterilization and cooking chamber to replace the air in the inner room can effectively prevent the generation of cold air masses in the inner room and ensure the sterilization effect. After the steam enters, it has strong penetration and fast temperature rise. There is no dead angle between the sterilized items and it can save a lot of energy.

[0010] 2. The equipment integrates drying and sterilization, and can be used for multiple purposes, solving the problem of needing to transfer materials between multiple devices during sterilization.

[0013] Furthermore, the heating host can be replaced with a hot air blower, which solves the need for workers to not have to use steam for sterilization and cooking, thereby reducing production costs.

[0014] Furthermore, the indoor return air induction plate and the side wall of the drying box form a trapezoidal structure, so that the hot air stays in the material rack area longer, while allowing the air in the material rack to flow to the heat exchanger.

[0015] Furthermore, a track is provided in the middle of the drying box, and a track partition door is provided above the track that can slide on the track. The track partition door can divide the drying box into two independent spaces, so that the staff can sterilize and dry different materials at the same time, thereby increasing work efficiency.

[0016] Furthermore, a dehumidification device is installed on the side wall of the drying box, so that the moisture in the drying room can be dissipated to the outside of the drying room more quickly when the equipment is drying, thereby increasing work efficiency.

[0017] Furthermore, a pressure relief device is installed on the side wall of the drying box, which automatically relieves pressure when the air pressure in the drying chamber is too high, solving the problem of material damage caused by excessive air pressure in the drying chamber and improving the production yield.

[0025] Example 1:

[0026] The embodiment is basically as shown in the attached Figure 1 As shown:

[0027] An integrated equipment for sterilizing, boiling and drying green tea, as shown in the attached Figure 1As shown, it includes a heating host 2, a drying box 1, a feeding door 3, and a heat exchanger. A material frame 5 is provided in the drying box 1, which is fixedly connected to the bottom of the drying box 1. A track 6 is provided in the central part of the drying box 1 along the axial direction. The track 6 is fixedly connected to the bottom of the drying box 1. The track 6 is provided with a first groove facing the top of the drying box 1. A track partition door 7 is provided on the track 6 and slides in the first groove through a pulley 30. The track partition door 7 divides the drying box 1 into two spaces by sliding. A stainless steel pipe 8 is provided around the material frame 5. The stainless steel pipe 8 is U-shaped and arranged around the material frame 5. The stainless steel pipe 8 is 5 cm apart from the side of the material frame 5. A number of holes are provided on the side wall of the stainless steel pipe 8 so that the gas inside the stainless steel pipe 8 is discharged to the inside of the drying box 1 through the holes. The stainless steel pipe 8 passes through the side wall of the drying box 1 and is connected to the control system 9. The control system 9 is connected to the heating host 2 through a hollow pipe, so that the hot steam generated by the heating host 2 can be transmitted to the stainless steel pipe 8 through the control system 9.

[0028] The heating main unit 2 is connected to the heating pipe 10, the heating pipe 10 passes through the side wall of the drying box 1 and is connected to the heat exchanger 4 inside the drying box 1. The heating main unit 2 is connected to the cooling pipe 11, the cooling pipe 11 passes through the side wall of the drying box 1 and is connected to the heat exchanger 4 inside the drying box 1. A circulating fan 12 is provided near the side wall of the drying box 1. The circulating fan 12 accelerates the air flow in the drying box by rotating the fan, and quickly drains the heat of the heat exchanger to the area where the material rack 5 is set in the drying box 1. An arc plate 13 is provided at the corner of the drying box 1.

[0029] A return air ducting plate 14 is provided in the drying box 1. The return air ducting plate 14 is provided with a rectangular frame. The bottom edge of the rectangular frame of the return air ducting plate 14 is fixedly connected to the bottom of the drying box 1, and the top edge opposite to the bottom edge of the rectangular frame of the return air ducting plate 14 is fixedly connected to the top of the drying box 1. The two sides of the return air ducting plate 14 are 20 cm apart from the side walls of the drying box 1, so that the material frame 5 and the circulating fan 12 and the heat exchanger are separated into two areas. The rectangular frame of the return air ducting plate 14 is evenly spaced with second baffles 41. The two sides of the second baffle 41 are fixedly connected to the rectangular frame of the return air ducting plate 14. The top of the second baffle 41 is inclined 45° toward the direction of the heat exchanger 4, so that the air in the area where the material frame 5 is located flows to the area where the heat exchanger 4 through the gap between the second baffles 41, thereby avoiding the material frame 5 close to the heat exchanger 4 from being excessively heated, resulting in unsatisfactory drying effect.

[0030] A pressure relief device 15 is installed on the side wall of the drying box 1. When the drying box 1 is filled with steam, the pressure relief device 15 detects the air pressure inside the drying box 1 in real time. When the pressure relief device 15 detects that the air pressure inside the drying box 1 exceeds 2 bar, it automatically opens the pressure relief valve to reduce the pressure inside the drying box 1, so that the air pressure inside the drying box 1 is maintained below 2 bar.

[0031] The specific implementation process is as follows:

[0032] The staff first places the material to be dried on the material frame 5, moves the track partition door 7 through the track 6 to divide the drying box into two independent spaces, and turns on the heating host 2 (a high-temperature heat pump drying unit produced by Guangdong Baishite Electric Co., Ltd., model BKGR10FD). The high-temperature and high-pressure steam generated by the heating host 2 is transmitted to the stainless steel pipe 8 through the hollow pipe and control system 9 (a pressure controller produced by Tianjin Bomansen Technology Development Co., Ltd., model PMS-2111). The high-temperature and high-pressure steam is injected into the drying box through the holes in the side wall of the stainless steel pipe 8, and the material to be dried inside the drying box is sterilized and sterilized at high temperature.

[0033] After 30 minutes of sterilization, the staff controls the heating host 2 to turn off the steam production function, and controls the heating host 2 to turn on the drying function. The heating host 2 transmits the generated hot air to the heat exchanger 4 through the heating pipe 10. The hot air in the heat exchanger 4 heats the surface of the heat exchanger 4. The hot air cooled in the heat exchanger 4 is returned to the heating host 2 through the cooling pipe 11. The heat exchanger 4 diffuses the heat to the surrounding area, so that the air around the heat exchanger 4 is heated. The heated air is diffused into the drying box 1 through the circulating fan 12. The wind blown by the circulating fan 12 is directed to the material frame 5 through the arc plate 13 set at the corner of the drying box 1, so that the temperature in the drying box 1 is balanced. The air dries the material to be dried at high temperature. The moisture generated during the drying process is discharged through the dehumidification device 16 (ceiling fresh air dehumidifier produced by Hangzhou Songyue Environmental Technology Co., Ltd., model SYD-500L). The dried air is drained to the vicinity of the heat exchanger through the return air duct 14 to be heated again.

[0034] Example 2:

[0035] The embodiment is basically as shown in the attached Figure 2-6 As shown: it includes a stainless steel pipe 8, and the stainless steel pipe 8 is provided with a piston sleeve 17 toward the side of the material frame 5. The internal space of the piston sleeve 17 is connected to the internal space of the stainless steel pipe 8. The piston sleeve 17 is provided with a hole to allow steam to spray out. A piston 18 is provided in the piston sleeve 17. One end of the piston 18 is fixedly connected to the side of the material frame 5 through a connecting rod 19. The material frame 5 is provided with a bracket 20 at the end away from the piston sleeve. The bracket 20 is fixedly connected to the bottom of the drying box 1. The bracket 20 is connected to the material frame 5 through a first spring 21, so that the material frame 5 slides back and forth under the action of the first spring 21. The material frame 5 is provided with a roller at one end close to the bottom of the drying box 1 to enable the material frame 5 to roll back and forth.

[0036] When the heating host 2 delivers high-temperature and high-pressure steam into the stainless steel pipe 8, the pressure in the stainless steel pipe 8 pushes the piston 18 to move toward the material frame 5, and the piston 18 pushes the material frame 5 to move through the connecting rod 19. When the piston 18 moves through the hole, the steam in the stainless steel pipe 8 is discharged to the inside of the drying box 1 through the hole. When the thrust exerted on the piston 18 is less than the first spring 21, the first spring 21 pulls the material frame 5 back, and the material frame 5 returns the piston 18 to its initial position through the connecting rod 19. At this time, the stainless steel pipe 8 has a hole blocked by the piston 18, causing the internal pressure of the stainless steel pipe 8 to continue to increase. This reciprocating cycle causes the material frame 5 to move back and forth under the action of high-temperature and high-pressure steam, causing the material to be sterilized on the material frame to be displaced and flipped, making the sterilization efficiency of the integrated equipment for sterilizing, steaming and drying higher. The heating main unit 2 is provided with a water inlet pipe 25, which is connected to the main pipe port of the T-shaped pipe 26. The branch pipe port of the T-shaped pipe 26 is connected to the side wall of the water pool 23, so that the internal space of the water inlet pipe 25 is connected to the water storage space of the water pool 23. A filter screen 28 is provided at the connection between the T-shaped pipe 26 and the water pool 23. Another branch pipe port of the T-shaped pipe 26 is connected to the pressure relief device 15 through the exhaust pipe 24, so that high-pressure steam can be sprayed into the T-shaped pipe 26 through the exhaust pipe 24. The pipe body of the exhaust pipe 24 is cut off in the radial direction, and an injection device 40 is provided at the cutoff of the pipe body of the exhaust pipe 24. The injection device 40 is an L-shaped tubular device. The air inlet at one end of the injection device 40 is fixedly connected to the cutoff of the exhaust pipe 24 near the pressure relief device 15, and the air outlet at the other end of the injection device 40 is fixedly connected to the cutoff of the exhaust pipe 24 near the T-shaped pipe 26, so that the exhaust pipe 24 and the injection device 40 are spatially connected. The injection device 40 is provided with a first groove 401 along the axial direction of the air inlet, and a stopper 402 is provided in the first groove 401. The stopper 402 is connected to the first groove 401 by a third spring 403, so that the stopper 402 moves toward the air outlet of the injection device 40 under the action of the third spring 403, thereby separating the air outlet and air inlet of the injection device 40. The side wall of the air inlet of the injection device 40 is provided with a second groove 40 4. The stopper 402 is provided with a third groove 405 at the second groove 404, and a steel ball 406 is provided in the second groove 404. The steel ball 406 is connected to the bottom of the second groove 404 by a fourth spring 407, so that the steel ball 406 is embedded in the third groove 405 under the action of the fourth spring 407. When the air pressure at the air inlet of the jet device 40 increases to 400 kPa, the air pressure pushes the stopper 402 toward the first groove 401, so that the air inlet and the air outlet space of the jet device 40 are connected. At this time, the steam will be quickly discharged from the air inlet to the air outlet of the jet device 40. When the air pressure in the air inlet direction is less than 200 kPa, the stopper 402 moves toward the air inlet of the jet device 40 under the action of the third spring 403, and the steel ball 406 is embedded in the third groove 405 on the side wall of the stopper 402 under the action of the fourth spring 407, so that the stopper 402 is fixed.

[0037] The other branch pipe opening of the T-shaped pipe 26 is provided with a first baffle 27, and the first baffle 27 is rotatably connected to the other branch pipe opening of the T-shaped pipe 26 through a hinge 29, so that the first baffle 27 can seal the main pipe opening connecting the T-shaped pipe 26 and the water inlet pipe 25 by rotation. The other end of the first baffle 27 connected to the hinge 29 is provided with an iron block 38, and the branch pipe opening connecting the T-shaped pipe 26 and the water inlet pipe 25 is provided with a first electromagnet 341, and the first electromagnet 341 is connected to the pressure switch 37 through a first wire 351. The pressure switch 37 is connected to the power supply. The wire 353 is connected to the power supply 36, and a second electromagnet 342 is provided at the connection between the T-shaped pipe 26 and the exhaust pipe 24. The second electromagnet 342 is connected to the pressure switch 37 through the second wire 352. The inner wall of the first channel connecting the pressure switch 37 and the first wire 351 is interference fit with the outer wall of the first wire 351, the inner wall of the second channel connecting the pressure switch 37 and the second wire 352 is interference fit with the outer wall of the second wire 352, and the inner wall of the power channel connecting the pressure switch 37 and the power wire 353 is interference fit with the outer wall of the power wire 353. The inner cavity of the pressure switch 37 is provided with a copper sheet 371, one end of which is hingedly connected to the power wire 353. The copper sheet 371 is connected to the inner wall of the pressure switch 37 via a second spring 373, so that the copper sheet 371 is deflected toward the second wire 352 under the action of the second spring 373, and the second electromagnet 342 is in the energized state. The pressure switch 37 is connected to the first groove 401 via a rubber tube 39, so that the pressure switch 37 is connected to the first groove 401 space. When the stopper 402 moves toward the first groove 401, the air in the first groove 401 is vented. The air pressure is transmitted to the pressure switch 37 through the rubber tube 39, increasing the pressure in the pressure switch 37. A T-shaped rubber block 372 is provided in the pressure channel connecting the pressure switch 37 and the rubber tube 39. The upper part of the T-shaped rubber block 372 is gap-fitted with the inner wall of the pressure switch 37, and the lower part of the T-shaped rubber block 372 is in contact with the copper sheet 371. When the T-shaped rubber block 372 is subjected to the air pressure transmitted by the rubber tube 39, it pushes the copper sheet 371 toward the direction of the No. 1 wire 351, so that the second electromagnet 342 is in a power-off state, and the first electromagnet 341 is also in a power-on state.

[0038] When the pressure relief device 15 releases pressure, high-pressure steam is discharged from the drying box 1 into the exhaust pipe 24. When the pressure in the exhaust pipe 24 exceeds 400 kPa, the steam will be quickly discharged to the T-shaped pipe 26 through the jet device 40. The high-pressure steam in the exhaust pipe 24 is discharged into the pressure channel of the pressure switch 37 through the rubber tube 39. The high-pressure steam in the pressure channel pushes the T-shaped rubber block 372. The T-shaped rubber block 372 deflects the copper sheet 371 toward the No. 1 wire 351, so that the second electromagnet 342 is in the power-off state, and the first electromagnet 341 is also in the power-on state. At the same time, the high-pressure steam blows the first baffle 27, so that the first baffle 27 rotates to the main port of the T-shaped pipe 26. The first electromagnet 341 fixes the iron block 38 by magnetic force, so that the first baffle 27 is fixed to the main port of the T-shaped pipe 26. At this time, the high-pressure steam can only be discharged through the branch pipe port connected to the T-shaped pipe 26 and the water tank 23. When discharged, the high-pressure steam hits the filter screen. 28 is flushed to flush away impurities attached to the filter 28, thereby avoiding the problem of poor water inlet due to excessive attachments to the filter. After the pressure relief device 15 completes the pressure relief work, the copper sheet 371 in the pressure switch 37 is biased towards the No. 2 wire 352 under the action of the second spring 373, so that the first electromagnet 342 is in a power-off state, and the second electromagnet 341 is also in a power-on state. At this time, the first baffle 27 moves toward the second electromagnet 342 under the action of gravity, and the second electromagnet 342 fixes the iron block 38 at the branch pipe opening connecting the T-pipe 26 and the exhaust pipe 24. The first baffle 27 blocks the branch pipe opening of the T-pipe 26 and the exhaust pipe 24, so that the water in the pool can only enter the water inlet pipe 25 through the main opening of the T-pipe 26, so that the heating host 2 can normally take in water. After the exhaust pipe 24 is exhausted, the air inlet and outlet of the jet device 40 are separated, so that the internal space of the exhaust pipe 24 is closed.

[0039] The side wall of the drying box 1 is provided with an air hole 32, and the inner wall of the drying box 1 is provided with a rubber sleeve 31. There is a 10 cm gap between the rubber sleeve 31 and the inner wall of the drying box 1. A part of the edge of the rubber sleeve 31 is sealed with the inner wall of the drying box 1 on the side where the feeding door 3 is provided, and the other part of the edge of the rubber sleeve 31 is sealed with the bottom of the drying box 1. When steam enters the drying box 1, the internal pressure of the drying box 1 increases, causing the rubber sleeve 31 to expand. During the expansion of the rubber sleeve 31, the air between the rubber sleeve 31 and the drying box 1 is discharged through the air hole 32. The rubber sleeve 31 It is connected to the material frame 5 through a transmission rod 33. When the transmission rod 33 discharges the steam inside the drying box 1 through the pressure relief device 15, the rubber sleeve 31 contracts rapidly due to the decrease in the internal pressure of the drying box 1. During the contraction process, the rubber sleeve 31 causes the material frame 5 to move rapidly toward the bracket 20 through the transmission rod 33. After the material frame 5 moves toward the bracket 20, it performs simple harmonic motion due to the rebound force of the first spring 21. During the movement of the material frame 5, the material to be sterilized is displaced and flipped, further improving the sterilization efficiency of the sterilization, cooking and drying integrated equipment.

[0040] The above is only an embodiment of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
