Technical Field
[0001] This utility model relates to the field of food drying technology, and in particular to a layered drying tray structure for improving the uniformity of food drying. Background Technology
[0002] Food drying technology plays a vital role in the food processing industry. With the continuous development of the food industry, the demands for food drying efficiency and quality are increasing. Traditional food drying methods mostly employ simple hot air drying or natural air drying. While these methods are simple and easy to implement, they suffer from numerous problems during the drying process, such as long drying times, uneven drying, and food accumulation. These problems severely affect the quality and taste of the food. In recent years, although some improved drying equipment has emerged, such as drying trays with turning devices, these devices still have some shortcomings in practical applications. For example, existing turning devices often use simple mechanical structures, resulting in unsatisfactory turning effects and a tendency for food to accumulate during turning, further exacerbating the problem of uneven drying. Furthermore, some equipment has unreasonable structural designs, making operation and maintenance inconvenient. These problems have limited the development of food drying technology, urgently requiring a new technology that can effectively solve these issues.
[0003] To address the aforementioned issues, this solution proposes a layered drying tray structure to improve the uniformity of food drying. This structure, through its unique design, aims to enhance the uniformity and efficiency of food drying while preventing food from piling up during turning, thus improving drying quality. Utility Model Content
[0004] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, this utility model provides a layered drying tray structure that improves the uniformity of food drying.

A support mechanism is provided at the top of the vertical support rod, and a hot air blower for drying food is provided on the support mechanism. The vertical pole is also equipped with a rotating mechanism, and a flipping mechanism is connected to the rotating mechanism; The flipping mechanism includes a vertical rod and a flipping plate vertically positioned at the bottom of the vertical rod. The top of the vertical rod has a threaded section, and the top of the flipping plate has an arc-shaped surface. A rotating mechanism drives the flipping plate to move in a circular motion along the drying surfaces of the upper, middle, and lower trays, thereby flipping the food. The arc-shaped surface prevents the food from moving forward during flipping, thus preventing the food from piling up.
[0006] The upper tray includes a circular drying base plate and an annular baffle plate disposed around the upper surface of the circular drying base plate; The middle tray includes a middle annular drying base plate and annular baffles set on the inner and outer sides of the upper surface of the middle annular drying base plate, with an intermediate base plate set on the inner side of the annular baffle. The bottom tray includes a bottom annular drying base plate and annular baffles set on the inner and outer sides of the upper surface of the bottom annular drying base plate, with an intermediate base plate set on the inner side of the inner annular baffles.
[0007] A fixing sleeve is provided in the middle of the intermediate base plate, and the fixing sleeve is sleeved with the vertical pole.

Two fixing plates are provided on one side of the fixing hoop, and a fixing plate is provided in the middle of the two fixing plates. A hot air blower fixing ring is provided on one side of the fixing plate. Matching threaded holes are opened on the fixing plates and the fixing plate. A threaded rod is provided in the threaded hole, and the two ends of the threaded rod are fixed to the fixing plate by nuts. The hot air blower's air outlet is positioned facing downwards on the upper, middle, and bottom trays.
[0010] The rotating mechanism includes an annular guide rail fixed to the outer wall of the fixed sleeve. An annular groove is formed on the outer wall of the annular guide rail.

A gear is arranged inside the gear groove. The gear meshes with the annular rack. The gear shaft is rotatably connected to the inner wall of the gear groove. The gear is driven to rotate by a motor. The motor is arranged inside the slider. A transverse connecting plate is provided on the outer wall of the slider.
[0011] The outer end of the connecting plate is provided with a threaded hole; The threaded section at the top of the vertical rod of the flipping mechanism corresponding to the upper tray is fixedly connected to the connecting plate by a nut, and the lower surface of the flipping plate slides against the upper surface of the circular drying base plate. The flipping mechanism corresponding to the middle tray and the bottom tray also includes a second connecting plate, and both ends of the second connecting plate are provided with threaded holes; The vertical rod of the flipping mechanism corresponding to the middle tray is connected to the first connecting plate through the second connecting plate. The threaded section at the top of the vertical rod is fixedly connected to one end of the second connecting plate through a nut. The other end of the second connecting plate is fixedly connected to the first connecting plate through a nut.

[0012] The diameter of the middle base plate inside the middle tray is equal to the diameter of the circular drying base plate, and the diameter of the middle base plate inside the bottom tray is equal to the diameter of the middle tray, forming a trapezoidal structure from top to bottom. This trapezoidal structure allows the food to fully contact the hot air from the hot air blower, thereby improving drying efficiency.
[0013] The hot air blower can be secured to the hot air blower fixing ring using ropes or wires.
[0014] The beneficial effects of the technical solution provided by this utility model embodiment are: (1) Improve drying uniformity: The rotating mechanism drives the turning mechanism, so that the food can be heated evenly on the tray, avoiding the problem of uneven drying of food in some areas in the traditional drying method, and improving drying efficiency and quality.

[0016] (3) Improved drying efficiency: The trapezoidal structure formed from top to bottom is more conducive to the food coming into full contact with the hot air of the hot air blower, thus improving the drying efficiency.
[0017] (4) Easy to operate and maintain: The connection between the rotating mechanism and the flipping mechanism is simple and is fixed by nuts, which makes it easy to install and disassemble. At the same time, the support mechanism of the hot air blower is reasonably designed, which makes it easy to maintain and replace the hot air blower. Attached Figure Description
