Description

Technical Field

[0001] This utility model relates to the field of freeze-dried black fungus processing technology, specifically to a vacuum drying device for freeze-dried black fungus. Background Technology

[0002] When making freeze-dried food using freeze-drying equipment, the water in the food must first be frozen at low temperature, and then a vacuum is drawn so that the food frozen at low temperature is in a suitable vacuum environment in the freeze-drying equipment. The frozen water molecules directly sublimate into water vapor and escape. Among them, the processing of wood ear fungus usually uses freeze-drying equipment for drying.

[0003] In the prior art, patent document CN220524483U discloses a microwave vacuum drying device, including a drying chamber, a microwave power supply, and a chassis. The drying chamber is located inside the chassis, and a microwave shielding plate is horizontally installed inside the drying chamber. A first motor is located inside the drying chamber, and a fixed rotating shaft is installed at the output end of the first motor. A microwave moisture meter is installed at the bottom end of the fixed rotating shaft, and a disc microwave source is installed inside the fixed rotating shaft. A turntable motor is located below the microwave shielding plate, and a material tray penetrating the microwave shielding plate is installed at the output end of the turntable motor via a coupling. A microwave power supply and a vacuum pump are installed at the bottom end of the drying chamber. This device emits microwaves by rotating, which affects the mutual coupling and heating uniformity between the microwave source ports due to the rotation speed between the ports. The heating uniformity of the rotating structure is significantly improved.

[0004] To address the common problems of poor heating uniformity and low energy utilization in existing drying devices, current technology utilizes the influence of the rotation speed between microwave source ports on the mutual coupling and heating uniformity between the ports. Compared with traditional static heating, the heating uniformity of the rotating structure is significantly improved. However, this method still results in the inconvenience of placing raw materials during use, thus reducing the practicality of the drying device. Utility Model Content

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] Example 1

[0028] like Figure 1-5 As shown, this utility model provides a vacuum drying device for freeze-dried black fungus, including a drying chamber 1; a refrigeration placement unit 2 disposed inside the drying chamber 1 for placing the fungus during drying; a PLC controller 3 disposed on the outer surface of the drying chamber 1 for control; and an air extraction unit 4 disposed on the top of the drying chamber 1. A vacuum pressure gauge is disposed on the front of the drying chamber 1, and a temperature and humidity meter is disposed inside the drying chamber 1. The refrigeration placement unit 2 includes a refrigeration component disposed inside the drying chamber 1 and a placement component disposed inside the drying chamber 1. The air extraction unit 4 includes an air extraction component disposed on the top of the drying chamber 1 and a dehumidification component disposed on the top of the drying chamber 1. The refrigeration component includes a cooler 21, the outer surface of which is detachably connected to the inner wall of the drying chamber 1. An insulation baffle 22, which is detachably connected to the inner wall of the drying chamber 1, is disposed on the outer side of the cooler 21. The placement component includes a mounting frame 23, the bottom surface of which is flush with the bottom of the inner wall of the drying chamber 1. The mounting frame 23 is fixedly connected to the outer surface of the mounting frame 23, and a placement frame 24 is fixedly connected to the outer surface of the mounting frame 23. A rolling roller 25 is rotatably connected to the inner wall of the placement frame 24. A sleeve 26 is fixedly connected to the upper surface of the placement frame 24, and a limit frame 27 is slidably connected to the inner wall of the sleeve 26. A spring is fixedly connected to the bottom surface of the limit frame 27 and a roller 28 is rotatably connected to the inner wall of the limit frame 27. When using the vacuum drying device for freeze-dried black fungus, first place the storage tray for storing freeze-dried black fungus on the outer surface of the placement frame 24, and use the cooperation of the placement frame 24 and the roller 28 to push the storage tray into the drying chamber 1 of the placement frame 24. After the storage tray is placed, the limit frame 27 will spring back, thereby using the limit frame 27 to assist in limiting the storage tray. After the black fungus is stored, seal the drying chamber 1, and use the PLC controller 3 to control the start of the cooler 21 on the inner wall of the drying chamber 1 to assist in the cooling of the interior of the drying chamber 1.

[0029] The cooling process causes the moisture to sublimate directly, and the temperature and humidity changes inside the drying chamber 1 are monitored using a thermometer and hygrometer, thereby accelerating the drying effect of freeze-dried black fungus.

[0030] Example 2

[0031] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the air extraction assembly includes a vacuum pump 46, the bottom surface of which is detachably connected to the upper surface of the drying chamber 1, and the input end of the vacuum pump 46 extends into the interior of the drying chamber 1. The dehumidification assembly includes an air extraction pipe 41, the outer surface of which is fixedly connected to the upper surface of the drying chamber 1, and the interior of which is connected to the interior of the drying chamber 1 via a pipe. An air extraction box 42, which is fixedly connected to the upper surface of the drying chamber 1, is fixedly connected to the outer surface of the air extraction pipe 41 via a pipe. A one-way valve 43 is fixedly connected to the upper surface of the air extraction box 42, and the output end of the one-way valve 43 is detachably connected to... The connecting pipe 44 has a detachable connection at one end to a vacuum pump 45 that is detachably connected to the upper surface of the drying chamber 1. When it is necessary to evacuate the inside of the drying chamber 1, the vacuum pump 46 can be started by the PLC controller 3 to assist in evacuating the inside of the drying chamber 1, thereby creating a vacuum state inside. The vacuum pressure inside the drying chamber 1 can be observed by the pressure gauge set on the front of the drying chamber 1. When the water vapor generated during the drying process of the wood ear fungus inside the drying chamber 1 is evacuated by starting the vacuum pump 45 in conjunction with the connecting pipe 44, the one-way valve 43 and the vacuum chamber 42, the water vapor inside the drying chamber 1 can be extracted with the help of the vacuum pipe 41, thereby increasing the drying effect of the wood ear fungus.

[0032] The working principle of this freeze-dried black fungus vacuum drying device will be explained in detail below.

[0033] like Figure 1-5 As shown, when using the vacuum drying device for freeze-dried black fungus, the storage tray for storing freeze-dried black fungus is first placed on the outer surface of the placement rack 24. The placement rack 24 and rollers 28 work together to push the storage tray into the drying chamber 1 inside the placement rack 24. After the storage tray is placed, the limiting frame 27 springs back, thus limiting the storage tray. After the black fungus is stored, the drying chamber 1 is sealed, and the PLC controller 3 controls the activation of the cooler 21 on the inner wall of the drying chamber 1 to assist in cooling the interior of the drying chamber 1. This can be achieved through the PLC controller. 3. Control the start of vacuum pump 46 to assist in evacuating air from the inside of drying chamber 1, thereby creating a vacuum state inside it, so that the water directly sublimates. Use a thermometer and hygrometer to monitor the temperature and humidity changes inside drying chamber 1, and use a pressure gauge set on the front of drying chamber 1 to observe the vacuum pressure inside drying chamber 1. When the water vapor generated during the drying process of wood ear fungus inside drying chamber 1 is activated, the air pump 45, in conjunction with connecting pipe 44, one-way valve 43 and air extraction box 42, uses air extraction pipe 41 to help extract the water vapor inside drying chamber 1, thereby increasing the drying effect of wood ear fungus.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
