DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment 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 making creative work are within the scope of protection of the utility model.
[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present embodiment discloses a sheet-shaped fruit and vegetable freeze-drying tray, comprising a bracket 1, an inner tray 2, a pressing plate 3, and a water receiving tray 4. The upper and lower ends of the bracket 1 are both open, and a support plate 11 is provided inside the bracket 1. The support plate 11 is located near the upper end of the bracket 1, and the support plate 11 is provided with a plurality of tray slots 14. The inner tray 2 is installed in the tray slot 14, and each tray slot 14 can hold an inner tray 2. The upper edge of the inner tray 2 is provided with a skirt 24, and the skirt 24 is mounted on the bracket 11. The four corners of the skirt 24 are provided with positioning holes 242. The upper edge of the bracket 11 is provided with a plurality of tray slots 14. The end face is provided with a positioning column 112 corresponding to the positioning hole 242. The corresponding insertion of the positioning column 112 and the positioning hole 242 provides a positioning function for the installation of the inner tray 2. The upper end face of the support plate 11 is provided with a limiting block 111, and the skirt edge 24 is provided with a limiting hole 241 corresponding to the limiting block 111. The limiting holes 241 are distributed along the skirt edge 24. The limiting holes 241 distributed along the skirt edge 24 cooperate with the limiting blocks 111 on the upper end face of the tray 11 to make the connection between the skirt edge 24 and the support plate 11 more firmly when the inner tray 2 is placed to hold sliced fruits and vegetables, and the inner tray 2 is placed to be deformed.
[0024] The material of the inner tray 2 is plastic or silicone. Plastic and silicone materials can easily take out the freeze-dried sliced fruits and vegetables from the inner tray 2. At the same time, the manufacturing cost of plastic and silicone materials is lower. The inner tray 2 can be replaced in time when it is damaged or cannot be cleaned. The inner tray 2 is a consumable replacement part.
[0025] The pressing plate 3 is fixedly installed on the bracket 1. The pressing plate 3 has the same shape as the supporting plate 11. The lower end face of the pressing plate 3 abuts against the upper end face of the skirt 24. The pressing plate 3 and the supporting plate 11 can clamp and fix the skirt 24. The positioning column 112 passes through the positioning hole 242 and the pressing plate 3 upward. The upper end of the positioning column 112 is provided with a threaded portion. The upper end of the positioning column 112 is installed with a nut 5. The lower end face of the nut 5 abuts against the upper end face of the pressing plate 3. The nut 5 presses the pressing plate 3 against the skirt 24.
[0026] The inner tray 2 is provided with a placement groove 21, which is open upwards, and the width of the placement groove 21 gradually decreases from top to bottom. The placement groove 21 can vertically place sliced fruits and vegetables. More sliced fruits and vegetables can be placed in the area of a tray than flat, the number of freeze-dried fruits and vegetables at one time is increased, and the production efficiency is higher. The placement groove 21 can play a certain clamping role at the lower end of the sliced fruits and vegetables vertically inserted in the placement groove 21. A plurality of air holes 23 are provided on both sides of the placement groove 21, and the air holes 23 are connected to the inner and outer sides of the placement groove 21. The air holes 23 can pass the cold air during vacuum freezing through The air holes 23 enter the placement groove 21, so that both sides of the sliced fruits and vegetables can be exposed to cold air, and moisture can also flow out through the air holes 23, so that the freeze-drying effect is better. The bracket 1 is provided with side holes 12, and the side holes 12 are connected to the inner and outer side walls of the bracket 1. The position of the side holes 12 corresponds to the position of the air holes 23. The side holes 12 can connect the inside and outside of the bracket 1, so that the air holes 23 are connected to the outside of the bracket 1, so that the freeze-drying effect is better. The pressing plate 3 is provided with a plate hole 31, and the plate hole 31 is located above the placement groove 21. The plate hole 31 corresponds to exposing the upper opening of the placement groove 21.
[0027] The water receiving tray 4 is detachably plugged into the bracket 1, and a slot 13 is provided at the lower end of the bracket 1. The edge of the water receiving tray 4 can be inserted into the slot 13, and the water receiving tray 4 can be inserted into the inside of the bracket 1 from one side of the bracket 1. The water receiving tray 4 is located at the lower end of the bracket 1, and a drainage hole 22 is provided at the bottom of the placement groove 21. The drainage hole 22 runs through the lower end surface of the placement groove 21. The drainage hole 22 can drain the juice of the sliced fruit and vegetable slices after they are placed in the placement groove 21 downward, so that the placement groove 21 remains dry and prevents the fruits and vegetables from sticking to the placement groove 21 after being freeze-dried. The drainage hole 22 is located above the water receiving tray 4. Since the trays are stacked, the water receiving tray 4 can collect the juice discharged from the drainage hole 22 to prevent it from dripping into the tray below.
[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
