[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The working principle of the vacuum drying oven is to use a vacuum pump to extract the air in the box, reduce the air pressure, and heat the sample to promote the evaporation of moisture. Under the vacuum state, the moisture in the items will evaporate quickly due to the low pressure, thereby achieving the drying effect; compared with traditional drying methods, vacuum drying can better retain the nutritional content and taste of food, and is widely used in health foods, dried fruits, meat products and other fields.

[0025] Embodiment 1:

[0026] Based on the technical defects of the existing technology that the uneven heating of the flaky food affects the drying effect and product quality, please refer to Figure 1-Figure 6 The utility model provides a vacuum drying oven for processing health food, which utilizes a swinging assembly 43 to make a flip panel 46 swing back and forth, so that the sheet food can be flipped back and forth on the flip panel 46, thereby avoiding the problem that the sheet food is heated unevenly during the drying process and affects the product quality. A processing chamber is provided inside the box body 1, and a plurality of groups of supporting assemblies 3 are provided on the inner wall of the processing chamber. A bracket mechanism 4 for flipping the sheet food so that it is heated evenly is placed between two groups of horizontally corresponding supporting assemblies 3; the sheet food is placed on the bracket mechanism 4, and then the bracket assembly with the food is placed on the supporting assembly 3 in the processing chamber, and finally the sheet food is vacuum dried.

[0027] To ensure that the flakes are heated evenly during drying, please refer to Figure 2 and Figure 3 The bracket mechanism 4 includes an outer frame 41 placed between the two supporting components 3, a swing component 43 is provided on one side of the outer frame 41, a shell 42 fixedly connected to the outer frame 41 is provided on the outer side of the swing component 43, a plurality of rotating shafts 44 are connected to the swing component 43, the rotating shafts 44 are rotatably connected in the outer frame 41, a turning panel 46 for turning over the sheet food through a reciprocating swinging motion is fixed on the rotating shaft 44 through a connecting block 45, the rotating shaft 44 is rotated by the swing component 43, and the rotating shaft 44 drives the turning panel 46 to swing left and right through the connecting block 45, so that the sheet food is turned left and right under the drive of the turning panel 46, thereby improving its heating uniformity.

[0028] Since there are multiple flip panels 46, to ensure that each flip panel 46 can move synchronously and perform flipping work, please refer to Figure 4The swing assembly 43 includes a motor 431 installed inside the housing 42, and a rotating block 432 is fixedly provided on the output shaft of the motor 431. One end of the rotating block 432 is hinged to one end of a toothed plate 434 through a connecting rod 433. A plurality of equally spaced gears 436 are provided below the toothed plate 434 and mesh with the gears. The gear 436 is fixedly connected to one end of the rotating shaft 44. The motor 431 is started and drives the rotating block 432 to rotate. The rotating block 432 drives the toothed plate 434 to move through the connecting rod 433. The toothed plate 434 drives the rotating shaft 44 to rotate by meshing with the gear 436. With the reciprocating motion of the toothed plate 434, the plurality of flip panels 46 can swing back and forth synchronously.

[0029] In order to improve the stability of the tooth plate 434 during reciprocating motion, two guide sliders 435 are fixed on the tooth plate 434. The two guide sliders 435 are respectively slidably set in two guide grooves opened on the outer frame 41. The movement of the guide sliders 435 in the guide grooves makes the tooth plate 434 more stable when moving.

[0030] To ensure that the sheet food can be turned over on the turning panel 46, the turning panel 46 is made into a "V"-shaped structure. In this way, as the turning panel 46 swings back and forth, the sheet food just turns over on the inside of the turning panel 46 to achieve the turning effect.

[0031] In order to facilitate the staff to check the drying condition, a door 2 with a transparent glass window is hinged on the front of the box body 1 at the outside of the processing room. The staff can see the inside of the processing room through the transparent glass window to understand the drying condition.

[0032] Embodiment 2:

[0033] When placing the bracket mechanism 4, in order to facilitate placing more bracket mechanisms 4 in the processing chamber, please refer to Figure 6 On the basis of the first embodiment, the supporting assembly 3 includes a hanger 31 that can support the outer frame 41, and a through hole is opened on the hanger 31, and an adjusting bolt 32 threadedly connected to the inner wall of the processing chamber is provided in the through hole, so that each bracket mechanism 4 can be placed separately on two supporting assemblies 3, thereby increasing the drying amount of flaky food, and the height of each hanger 31 can be adjusted, which can better control the air circulation and ensure that the hot air evenly covers each bracket assembly.

[0034] Through the above embodiments, it can be known that: by evenly placing the sheet food on the flip panel 46, then opening the box door 2 and placing the bracket mechanism 4 on the supporting assembly 3, and then closing the box door 2, during the drying process, starting the motor 431 and driving the rotating block 432 to rotate, the rotating block 432 drives the tooth plate 434 to move through the connecting rod 433, the tooth plate 434 drives the rotating shaft 44 to rotate through the meshing action with the gear 436, and the rotating shaft 44 drives the flip panel 46 to swing back and forth through the connecting block 45. With the reciprocating motion of the tooth plate 434, the multiple flip panels 46 can swing back and forth synchronously, and the sheet food just flips left and right on the inner side of the flip panel 46 to achieve the effect of flipping.

[0035] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
