Abstract
Description
Technical Field
[0001] This utility model relates to the field of houttuynia cordata processing technology, and in particular to an energy-saving device for low-temperature dehydration of houttuynia cordata. Background Technology
[0002] Houttuynia cordata is a herb with various medicinal and edible values. During the processing of Houttuynia cordata, it often needs to be dehydrated to facilitate subsequent storage, transportation and further processing.
[0003] Traditional dehydration methods, such as high-temperature drying, can easily lead to the loss of active ingredients in houttuynia cordata, affecting its quality. Therefore, low-temperature dehydration is often used to dehydrate houttuynia cordata.
[0004] Existing methods for low-temperature dehydration of houttuynia cordata require the use of a heater to continuously heat the internal environment of the dehydration chamber. This allows the houttuynia cordata placed inside the chamber to gradually lose moisture under these warm conditions, thus achieving the purpose of dehydration. However, this traditional dehydration method requires the use of an additional heater to maintain the entire dehydration process, which undoubtedly consumes a certain amount of energy, resulting in energy waste. Therefore, an energy-saving device for low-temperature dehydration of houttuynia cordata is proposed to solve the above problems. Utility Model Content

[0026] like Figure 1-5 As shown, the present invention proposes an energy-saving device for low-temperature dehydration of Houttuynia cordata, including a drying shell 2 with its opening facing forward. An outer frame 5 is hinged to the opening of the drying shell 2. The bottom of the drying shell 2 is provided with multiple spaced support feet 3. A heat insulation shell 11 is connected to the rear end face of the drying shell 2. A hot water exchange mechanism is provided inside the heat insulation shell 11. A fan 10 is provided on the rear end face of the heat insulation shell 11. Sliding tracks 16 are arranged in pairs. Multiple sets of sliding tracks 16 are equidistantly distributed between the left and right inner walls of the drying shell 2. A placement component is slidably connected between each set of sliding tracks 16. A collection component is placed on the inner bottom wall of the drying shell 2.
[0027] In this invention, when low-temperature dehydration of Houttuynia cordata is required, hot water generated from the waste heat of the workshop extraction tank is used as a heat source. The hot water is introduced into the hot water exchange mechanism, and the hot air generated by the hot water exchange mechanism is blown into the interior of the drying shell 2 by the fan 10. This can keep the fresh Houttuynia cordata roots inside the drying shell 2 below 50°C for low-temperature drying, which can retain some of the flavor of the fresh Houttuynia cordata roots and avoid the destruction of its active ingredients. By using hot water from the waste heat of the workshop extraction tank as a heat source, this heat source can enter the interior of the drying shell 2, thereby improving the overall system energy efficiency and reducing energy waste.
[0028] In an optional embodiment, the hot water exchange mechanism includes an outlet pipe 7, a heat exchange pipe 12, and an inlet pipe 9. The heat exchange pipe 12 is located inside the heat insulation shell 11. One end of the outlet pipe 7 passes through the outer end face of the heat insulation shell 11 and is connected to the outlet of the heat exchange pipe 12. One end of the inlet pipe 9 passes through the outer end face of the heat insulation shell 11 and is connected to the inlet end of the heat exchange pipe 12. The inlet end of the inlet pipe 9 is connected to the workshop extraction tank. At this time, the hot water generated by the waste heat of the workshop extraction tank can enter the interior of the heat exchange pipe 12 through the inlet pipe 9. The heat source generated by the hot water flow inside the heat exchange pipe 12 is used. After use, the hot water is discharged through the outlet pipe 7. The heat insulation shell 11 can be used for heat insulation.
[0029] It should be noted that when low-temperature dehydration of houttuynia cordata is required, the hot water generated by the waste heat of the extraction tank in the workshop is used as a heat source. The hot water is transported to the inside of the heat exchange tube 12 through the water inlet pipe 9. When the hot water flows inside the heat exchange tube 12, the heat exchange tube 12 may generate hot air. This hot air will heat the inside of the heat insulation shell 11. This hot air can be sent to the inside of the drying shell 2 by the fan 10.
[0030] In an optional embodiment, the heat exchange tube 12 has a threaded structure, and a manual valve 8 is provided on the outer end face of the water inlet pipe 9.
[0031] It should be noted that, since the heat exchange tube 12 has a threaded structure, the heat source generated by the hot water flowing inside the heat exchange tube 12 can be fully utilized; the manual valve 8 can be rotated to change the opening degree of the manual valve 8, so as to control the flow rate of the inlet pipe 9.
[0032] In an optional embodiment, an observation glass 4 is provided on the inner end face of the outer frame 5, and a first handle 6 is provided on the front end face of the outer frame 5 and on the right side of the observation glass 4.
[0033] It should be noted that the inside of the drying shell 2 can be observed through the observation glass 4, and the outer frame 5 can be easily opened through the first handle 6.
[0034] In an optional embodiment, the device further includes a temperature control instrument 1 and a temperature detector 19. Multiple temperature detectors 19 are spaced apart on the inner top wall of the drying shell 2, and the temperature control instrument 1 is disposed on the outer end face of the drying shell 2. The multiple temperature detectors 19 and the temperature control instrument 1 are electrically connected.
[0035] It should be noted that the temperature inside the drying shell 2 can be detected by multiple temperature detectors 19, and the detected temperature can be transmitted to the temperature control instrument 1 for display, thus facilitating the observation of the temperature inside the drying shell 2.
[0036] In an optional embodiment, the placement assembly includes a limiting frame 14, a placement plate 13, and a second handle 15. The placement plate 13 is slidably connected between each set of sliding rails 16. The limiting frame 14 is located on the upper end face of the placement plate 13, and the second handle 15 is located on the outer end face of the placement plate 13 and close to the opening of the drying shell 2.
[0037] It should be noted that when the houttuynia cordata needs to be dehydrated, the houttuynia cordata is first placed on the placement plate 13 and located inside the limiting frame 14. Then, the placement plate 13 is inserted into the groove of a set of two sliding rails 16, so that the houttuynia cordata can be placed inside the drying shell 2. And the placement plate 13 can be easily removed from the groove of the sliding rails 16 on both sides by means of the second handle 15.
[0038] The placement plate 13 can be used to place houttuynia cordata. The limiting frame 14 can limit the houttuynia cordata to the placement plate 13. The second handle 15 can facilitate the movement of the placement plate 13 in the sliding grooves of the sliding rails 16 on both sides connected to it.
[0039] In an optional embodiment, the collection assembly includes a collection box 18 and a third handle 17. The collection box 18 is placed on the inner bottom wall of the drying housing 2 with its opening facing upwards. The third handle 17 is located on the outer end face of the collection box 18 and is close to the opening of the drying housing 2.
[0040] It should be noted that when the houttuynia cordata is taken out or placed inside the drying shell 2, some impurities of the houttuynia cordata will fall into the collection box 18. When there are many impurities inside the collection box 18, the collection box 18 can be easily pulled out through the third handle 17, and then the impurities inside the collection box 18 can be cleaned. After cleaning, the collection box 18 can be placed on the inner bottom wall of the drying shell 2.
