[0002] When processing freeze-dried fruit and vegetable foods, all kinds of fruits and vegetables need to be pre-processed, and they need to go through processes such as selection, rinsing, blanching, and cooling before freeze-drying. For example, various fruits and vegetables, such as apples, strawberries, carrots, shiitake mushrooms, and mushrooms, need to be placed on a support rack after processing, and then placed in a cold storage for quick freezing;

[0003] The quick freezing support frame is usually formed by welding metal pipes, such as Figure 1 As shown, it includes a frame 20, a multi-layer support plate 21 is welded inside the frame 20, and a freezing plate 22 for carrying freeze-dried fruits and vegetables is placed on the support plate 21. The structure is simple and it is convenient to quickly freeze the freeze-dried fruits and vegetables;

[0004] However, the existing trays for freeze-drying fruits and vegetables are simple in structure and only have a simple carrying and storage function. The freezing time is long, and the tray is easily frozen on the device during the freezing process, which is inconvenient to take out. Moreover, the device is usually a fixed structure, which is very inconvenient to place and take out, greatly reducing its work efficiency. Utility Model Content

[0010] In order to facilitate the movement of the equipment, as a preferred embodiment of the tray rack for freeze-drying fruits and vegetables of the utility model, the bottom ends of the two side panels are provided with a plurality of universal wheels.

[0011] A tray for freeze-drying fruits and vegetables comprises a tray arranged inside a support frame, wherein positioning holes matching positioning rods are provided at four corners of the periphery of the tray, a plurality of evenly distributed ridges are fixedly connected to the inner bottom end of the tray, and a plurality of evenly distributed through holes are provided at the inner bottom end of the tray.

[0012] In order to facilitate taking the tray, as a preferred tray for freeze-drying fruits and vegetables of the utility model, handles are fixedly connected to the left and right sides of the upper end surface of the tray.

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

[0014] The support frame is used to support the tray. The support frame is a frame structure. On the one hand, it is convenient for cold air to circulate between the multi-layer support frames to improve the quick freezing efficiency. On the other hand, it reduces the contact area between the tray and the bottom of the support frame, thereby effectively avoiding the situation that the tray and the support frame are frozen and stuck after quick freezing, which is inconvenient to take out. It is more convenient to use. If the support frame is frozen, the cylinder is started to drive the push block to move upward, and the push block pushes the tray from the bottom, so that the tray can be disassembled and taken out more conveniently.
