Technical Field

[0001] This utility model relates to the field of vacuum drying ovens, specifically a vacuum drying oven for food inspection. Background Technology

[0002] Vacuum drying technology plays a vital role in food processing and inspection. It extends the shelf life of food by removing moisture while preserving its nutritional components and flavor. Vacuum drying ovens, as laboratory equipment, are widely used in food testing for drying reference standards and samples.

[0003] In conventional vacuum drying ovens, the trays are supported only by partition strips on the inner wall of the oven, which greatly limits the height adjustment of the trays and makes it inconvenient to arrange materials reasonably. This restricts the flexibility of the drying oven and the effective utilization of heat energy. Utility Model Content

[0004] The purpose of this invention is to provide a food inspection vacuum drying oven to solve the problem of the limited adjustment of the tray height in conventional vacuum drying ovens mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a food inspection vacuum drying oven, comprising a vacuum drying device and several trays. The cavity wall of the vacuum drying device has multiple protrusions integrally formed on both sides for supporting the trays. Each tray has a frame rod rotatably mounted on its left and right sides, consisting of a pair of first U-shaped rods, a second U-shaped rod, and several connecting blocks. The tray is placed on the protrusions via the frame rods. Limiting blocks are slidably mounted on the left and right sides of the tray via elastic members. The limiting blocks extend through the elastic members to contact the frame rods, allowing the elastic members to adjust the angle of the frame rods in conjunction with the limiting blocks and connecting blocks.

[0009] Preferably, a pair of extension sections are integrally formed on the left and right sides of the tray. One side of the extension section is rotatably connected to the connecting blocks at both ends of the frame rod, and a pull rod is slidably installed on the other side. The limiting block is fixedly installed at the end of the pull rod. The elastic member is a spring sleeved on the pull rod, and the two ends of the spring are in contact with the limiting block and the extension section, respectively.

[0010] Preferably, a pull ring is fixedly installed on one side of the pull rod.

[0011] Preferably, the top of the tray has a plurality of equidistant through holes.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6This utility model provides a technical solution: a food inspection vacuum drying oven, comprising a vacuum drying device 1 and several trays 2. The top of each tray 2 has several equidistantly arranged through holes 7, which allow the heating medium to more evenly transfer heat to the material on the tray 2, thereby improving drying efficiency. The cavity walls of the vacuum drying device 1 are integrally formed with multiple protrusions 3 for supporting the trays 2. The protrusions 3 are arranged in three rows, with the middle row of protrusions 3 staggered from the protrusions on both sides. This arrangement allows users to easily adjust the height of the trays 2 according to the height of the material. The compact arrangement of the protrusions 3 also improves the flexibility of adjusting the spacing between the trays 2. To improve food drying efficiency, the left and right sides of the tray 2 are respectively equipped with a frame rod consisting of a pair of first U-shaped rods 5, a second U-shaped rod 6, and several connecting blocks 8. The tray 2 is placed on the protrusion 3 via the frame rod. Limiting blocks 12 are slidably installed on the left and right sides of the tray 2 via elastic members. The vertical cross-section of the limiting block 12 is rectangular, but it can also be other polygons. The advantage of using polygons is that it is convenient to limit the angle of the connecting blocks 8. The limiting block 12 extends to contact the frame rod via the elastic member. A pair of second U-shaped rods 6 are respectively fixedly installed on the left and right sides of the first U-shaped rod 5. The same connecting block 8 is fixedly installed at the connection between the second U-shaped rod 6 and the first U-shaped rod 5. The connecting block 8 has a socket 11 that matches the limiting block 12. The second U-shaped rod 6 and the first U-shaped rod 5 form a 90° angle so that the elastic component can adjust the angle of the frame rod by cooperating with the limiting block 12 and the connecting block 8. A pair of extension sections 4 are integrally formed on the left and right sides of the tray 2. One side of the extension section 4 is rotatably connected to the connecting blocks 8 at both ends of the frame rod, and the other side is slidably installed with a pull rod 9. A pull ring is fixedly installed on one side of the pull rod 9. The limiting block 12 is fixedly installed at the end of the pull rod 9. The elastic component is a spring 10 sleeved on the pull rod 9. The two ends of the spring 10 are in contact with the limiting block 12 and the extension section 4, respectively. When it is necessary to adjust the angle of the frame rod, the spring 10 on one side is pulled at the same time. The pull rings on the pair of pull rods 9 slide on the extension section 4 to compress the spring 10 and drive the limiting block 12 away from the insertion hole 11, releasing the limitation on the frame rod. Then, the frame rod is rotated so that the second U-shaped rod 6 or the first U-shaped rod 5 rotates to be flush with the tray 2. The position of the tray 2 on the protrusion 3 can be adjusted according to the height of the material. This application uses the tray 2, the first U-shaped rod 5, the second U-shaped rod 6, the connecting block 8, the pull rod 9 and the elastic component to form an adjustable drying oven tray, which can adapt to materials of different sizes, making the use of the drying oven more flexible. By adjusting the position of the tray 2, the heat energy inside the oven can be utilized more effectively, reducing energy waste and improving drying efficiency.
