Description

Technical Field

[0001] This utility model relates to the field of drying chambers, specifically a novel drying chamber for vacuum freeze-drying of food. Background Technology

[0002] A food vacuum freeze-drying device is a supporting equipment for food drying and processing. Nowadays, people's living standards are getting higher and higher, and the requirements for food processing are also getting higher and higher. In order to increase the storage time of food, vacuum drying is usually used. With the continuous development of technology, people's requirements for the manufacturing process of food vacuum freeze-drying devices are also getting higher and higher.

[0003] According to the published patent 202322212519.3, a food vacuum freeze-drying device includes a device body, a cover plate rotatably connected to one side of the device body, a connecting component hinged to the top of the device body, one end of the connecting component connected to the cover plate, clamping moving parts fixed to both sides of the device body, a support frame fixed below the cover plate, a support component installed above the support frame, and a placement plate slidably connected inside the device body.

[0004] However, in practice, traditional vacuum freeze-drying chambers for food require moving placement plates out of the unit when removing food. This method, due to the multiple placement plates inside the chamber, necessitates multiple separate moving mechanisms to move different plates out, which is inconvenient. Furthermore, vacuum freeze-drying works by first freezing the water-containing material below its eutectic point temperature, turning the water into ice. Then, under appropriate temperature and vacuum, the ice sublimates into vapor and escapes from the material. A cold trap then condenses the vapor back into ice, resulting in dried food. This process requires heating the water-containing material. Existing devices typically place the heating mechanism in a fixed position, leading to inconsistent heating effects at different locations and impacting the overall effectiveness of heating the water-containing material. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, adapt to practical needs, and provide a novel drying chamber for vacuum freeze-drying of food. This addresses the problem that in current traditional vacuum freeze-drying chambers, removing food from the device requires moving a placement plate out of the chamber. This method, due to the presence of multiple placement plates inside the chamber, necessitates multiple different moving mechanisms to move different plates out, which is inconvenient. Furthermore, vacuum freeze-drying works by first freezing the water-containing material below its eutectic point temperature, turning the water into ice. Then, under appropriate temperature and vacuum, the ice sublimates into vapor and escapes from the material. A cold trap is then used to condense the vapor back into ice, thus obtaining dried food. Therefore, this process requires heating the water-containing material. Existing devices typically place the heating mechanism in a fixed position, resulting in inconsistent heating effects at different locations, thus affecting the effectiveness of heating the water-containing material.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a novel drying chamber for vacuum freeze-drying of food is designed, including a drying chamber body, a control host installed at the front end of the drying chamber body, protective covers provided on both sides of the drying chamber body, one end of a first electric heating tube fixed at each of the four corners of both ends of the drying chamber body, one end of the first electric heating tube extending into a slot opened on the side of the protective cover, a moving component provided at the top of the drying chamber body, which simultaneously drives the protective covers on both sides of the drying chamber body to move, and a rotating component provided on both sides of the drying chamber body.

[0007] Preferably, the moving component includes a dual-axis motor, a threaded rod, a fixing block, and a limiting block.

[0008] Preferably, the dual-axis motor is installed on the top of the drying chamber, and one end of a threaded rod is connected to both sides of the dual-axis motor. The other end of the threaded rod passes through the fixing block and is fixed to the limit block.

[0009] Preferably, the screw hole in the fixing block is threadedly connected to the threaded rod, and a protective cover is fixed to the bottom of the fixing block.

[0010] Preferably, the rotating assembly includes multiple grooves, a drive motor, a rotating column, a rotating plate, and a protective mesh cover.

[0011] Preferably, a plurality of the grooves are formed on both sides of the drying chamber, a drive motor is installed at one end of the groove, a rotating column is connected to one end of the drive motor, a rotating plate is fixed at the end of the rotating column away from the drive motor, and protective net covers are installed at both the upper and lower ends of the rotating plate.

[0012] Preferably, the rotating plate has multiple cavities inside, each cavity housing a second heating element. One end of the rotating plate has a mounting groove, inside which a battery is installed. The surface of the battery has a USB charging port.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model combines a drying chamber, protective covers, and a moving component. The moving component simultaneously moves the protective covers on both sides of the drying chamber, directly exposing the food inside. This allows workers to easily retrieve food from different locations within the drying chamber, improving efficiency. Furthermore, protective mesh covers are installed above and below the rotating plate, allowing food to be placed inside these covers, thus increasing the storage capacity. During storage, when drying is required, a drive motor rotates the food stored above and below the rotating plate. This new technology allows for heat contact with different locations within the drying chamber, enhancing the heating effect on food. It solves the problem of traditional vacuum freeze-drying chambers for food, where removing food from the device requires moving the placement plates out of the chamber. This method is inconvenient because multiple placement plates are installed inside the drying chamber, necessitating multiple different moving mechanisms to move each plate out of the chamber. Furthermore, existing devices typically place the heating mechanism in a fixed position, resulting in inconsistent heating effects on food in different locations, which affects the heating of materials containing moisture.

[0015] 2. This utility model combines a rotating plate, a cavity, and second heating elements, allowing multiple second heating elements to be installed on the inner wall of the rotating plate. When food needs to be heated, the rotating plate can be directly heated using these multiple second heating elements, thus cooperating with multiple external first heating elements to heat the food simultaneously from both the outside and inside. This further improves the heating effect and solves the technical problem that existing devices typically place the heating mechanism in a fixed position, resulting in inconsistent heating effects for food at different locations, which affects the heating of water-containing materials.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A novel drying chamber for vacuum freeze-drying of food, see [link to example]. Figures 1 to 3The system includes a drying chamber 1, a control host 101 mounted at the front end of the drying chamber 1, protective covers 102 on both sides of the drying chamber 1, and one end of a first electric heating tube 209 fixed at each of the four corners of both ends of the drying chamber 1. One end of the first electric heating tube 209 extends into a slot 210 opened on the side of the protective cover 102. A moving component is provided at the top of the drying chamber 1, which simultaneously moves the protective covers 102 on both sides of the drying chamber 1. Rotating components are provided on both sides of the drying chamber 1. Multiple food items are first placed into multiple protective mesh covers 208, and then... Multiple protective net covers 208 are installed at the upper and lower positions of multiple rotating plates 207. After installation, when food needs to be heated, multiple first heating elements 209 can be turned on. The multiple first heating elements 209 generate heat inside the protective cover 102 to heat the food. During the food heating process, multiple drive motors 205 are turned on. The drive motors 205 drive the rotating column 206, which in turn drives the rotating plate 207 to rotate. The rotating plate 207 then drives the protective net covers 208 at the upper and lower positions. The food rotates, allowing it to come into contact with heat at different locations, ensuring even heating. When food needs to be removed, the dual-axis motor 2 is activated. The motor 2 drives the threaded rod 201, which in turn moves the fixed block 202. The fixed block 202 then moves the protective mesh cover 208, simultaneously opening the protective covers 102 on both sides of the drying chamber 1, directly exposing the food inside. This allows staff to directly retrieve food from different locations within the drying chamber 1, improving efficiency. This solves the problem of traditional vacuum freeze-drying drying chambers where removing food requires moving placement plates out of the device. This method, with multiple placement plates inside the drying chamber, necessitates multiple moving mechanisms to move different plates out, which is inconvenient. Furthermore, existing devices typically place the heating mechanism in a fixed position, resulting in inconsistent heating effects at different locations, impacting the effectiveness of heating materials containing moisture.

[0022] For details, see Figure 1 and Figure 2 The moving component includes a dual-axis motor 2, a threaded rod 201, a fixing block 202, and a limiting block 203.

[0023] Further, see Figure 1 and Figure 2 The dual-axis motor 2 is installed on the top of the drying chamber 1. Both sides of the dual-axis motor 2 are connected to one end of the threaded rod 201. The other end of the threaded rod 201 passes through the fixing block 202 and is fixed to the limit block 203.

[0024] It is worth noting that, see Figure 1 and Figure 2 The screw hole in the fixing block 202 is threadedly connected to the threaded rod 201, and a protective cover 102 is fixed to the bottom of the fixing block 202.

[0025] It is worth noting that, see Figure 2 The rotating assembly includes multiple grooves 204, a drive motor 205, a rotating column 206, a rotating plate 207, and a protective mesh cover 208.

[0026] It is worth mentioning that, see Figure 2 Multiple grooves 204 are formed on both sides of the drying chamber 1. A drive motor 205 is installed at one end of the groove 204. A rotating column 206 is connected to one end of the drive motor 205. A rotating plate 207 is fixed at the end of the rotating column 206 away from the drive motor 205. Protective net covers 208 are installed at both the upper and lower ends of the rotating plate 207.

[0027] It is worth emphasizing that, see Figure 3 The rotating plate 207 has multiple cavities 3 inside, each housing a second heating element 301. A mounting groove 302 is located at one end of the rotating plate 207, housing a battery 303 connected to the second heating element 301. A USB charging port 304 is located on the surface of the battery 303. Because of the multiple cavities 3 and second heating elements 301 inside the rotating plate 207, the second heating elements 301 can be activated during the heating of multiple food items by the first heating element 209. This allows for heating from within the rotating plate 207, dissipating heat from the interior of the accumulated food items. Working in conjunction with the first heating element 209, the second heating elements can simultaneously heat the food from both the outside and inside, further improving the heating effect. This solves the technical problem of existing devices where the heating mechanism is typically located in a fixed position, resulting in inconsistent heating effects for food items in different locations, thus affecting the heating of water-containing materials.

[0028] When using a novel drying chamber for vacuum freeze-drying of food, multiple food items are first placed into multiple protective mesh covers 208. Then, the protective mesh covers 208 are installed at the upper and lower positions of multiple rotating plates 207. After installation, when heating of the food is required, multiple first heating elements 209 are activated. These first heating elements 209 generate heat inside the protective cover 102, thereby heating the food. During the heating process, multiple drive motors 205 are activated, which drive a rotating column 206. The rotating column 206 drives the rotating plates 207 to rotate, which in turn rotates the protective mesh covers 208 and the food at the upper and lower positions. This ensures that the food comes into contact with heat at different locations, resulting in uniform heating of the food at different positions. When it is time to remove the food... The dual-axis motor 2 can be turned on, driving the threaded rod 201, which in turn moves the fixed block 202. The fixed block 202 then moves the protective mesh cover 208, thereby simultaneously opening the protective covers 102 on both sides of the drying chamber 1, directly exposing the food inside the drying chamber 1. This allows staff to directly retrieve food from different locations within the drying chamber 1, improving the efficiency of food retrieval. Since multiple cavities 3 and a second heating element 301 are provided inside the rotating plate 207, the second heating element 301 can be activated during the heating of multiple foods by the first heating element 209. This allows for heating from inside the rotating plate 207, dissipating heat from the interior of the accumulated food. When used in conjunction with the first heating element 209, the food can be heated simultaneously from both the outside and inside, further enhancing the heating effect.
