Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a portable freeze-drying tray for receiving materials. Background Technology

[0002] In the freeze-drying process of food, the freeze-drying tray (also known as a material tray or pallet) is a key component that holds the materials to be freeze-dried. It comes into direct contact with the food and is primarily made of food-grade stainless steel, food-grade aluminum alloy, or food-grade engineering plastics. Currently, freeze-drying trays vary in length and width ratios to match different freeze dryer sizes. However, all freeze-drying trays are cubical structures with a fixed bottom and four sides and an open top, suitable for freeze-drying solid or liquid materials. However, at the end of the freeze-drying process, the freeze-dried material must be manually removed from the tray by workers. This is inefficient, results in material residue, and is inconvenient to operate. Utility Model Content

[0003] Therefore, in order to address the above problems, this utility model provides a portable freeze-drying tray for receiving materials, which solves the problem of low efficiency in the material receiving process of existing freeze-drying trays.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A portable freeze-drying tray includes an open box body with an opening on one side. A flip cover and a first fixing member are provided at the opening. The bottom of the flip cover is rotatably connected to the box body. At least one side of the flip cover is fixed to the box body by the first fixing member. A movable plate and a second fixing member are provided inside the box body. The movable plate is fixed to the side wall of the box body by at least one of the second fixing members, so that the movable plate is in contact with one side wall of the box body.

[0006] Furthermore, the first fixing member has a U-shaped cross-section, and the two side walls of the box are folded inward or outward to form folded edges. The first fixing member is fixed to the flip cover by clamping the folded edges.

[0007] Furthermore, the box body and the flip cover are made of food-grade stainless steel, and the movable plate is made of food-grade industrial plastic.

[0008] Furthermore, the top of the movable plate is provided with a gripping part.

[0009] Furthermore, the movable plate is fitted against the side wall directly opposite the opening.

[0010] Furthermore, the second fixing member has a U-shaped cross-section, and the second fixing member is fixed by clamping the top of the side wall of the box body to the top of the movable plate.

[0011] Furthermore, the movable plate is provided with sliding blocks on both sides, and the box body is provided with slide rails on the side walls on both sides of the movable plate, with each sliding block cooperating with each slide rail.

[0012] Furthermore, the bottom of the flip cover is rolled up to form a covering cavity, and a rotating rod is provided inside the covering cavity. The two ends of the rotating rod are rotatably connected to the box body.

[0013] Furthermore, torsion springs are fitted at both ends of the rotating rod, with one end of the torsion spring connected to the box body and the other end of the torsion spring connected to the flip cover.

[0014] Furthermore, the torsion spring is a compression torsion spring, and when the flap is not constrained by the first fixing member, the flap folds outward by 90°-270° under the action of the torsion spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Compared with ordinary freeze-drying trays, this invention can not only achieve normal pre-freezing and drying, but also achieve rapid material collection after freeze-drying by moving the movable surface of the freeze-drying tray. This eliminates the need to manually remove the materials from the freeze-drying tray one by one, reducing labor costs and workload. In particular, for freeze-dried powder products containing active microorganisms such as probiotics, it can reduce secondary pollution caused by manual material collection.

[0026] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] Example:

[0028] like Figures 1 to 3 As shown, a portable freeze-drying tray for receiving materials includes an open box 1. The box 1 has an opening 11 on one side, and a flip cover 2 and a first fixing member 21 are provided at the opening 11. The bottom of the flip cover 2 is rotatably connected to the box 1. The two sides of the flip cover 2 are fixed to the box 1 by the first fixing member 21. The box 1 has a movable plate 3 and a second fixing member 31 inside. The movable plate 3 is fixed to the side wall of the box 1 by two second fixing members 31, so that the movable plate 3 is in contact with one side wall of the box 1. The top of the movable plate 3 is provided with a handle 32.

[0029] The movable plate 3 is attached to the side wall directly opposite the opening 11; the second fixing member 31 has a U-shaped cross-section and is fixed by clamping the top of the side wall of the box 1 to the top of the movable plate 3.

[0030] The movable plate 3 is provided with sliding blocks 33 on both sides, and the box body 1 is provided with slide rails 12 on the side walls on both sides of the movable plate 3. Each sliding block 33 is respectively engaged with each slide rail 12.

[0031] The first fixing member 21 has a U-shaped cross-section. The two side walls of the box body 1 are folded inward or outward to form folded edges 13. The first fixing member 21 is fixed to the flip cover 2 by clamping the folded edges 13.
