Description

Technical Field

[0001] The utility model belongs to the field of tea processing, and particularly relates to a freeze-drying chamber for tea dehydration. Background Art

[0002] The working principle of the tea dehydration freeze-drying chamber mainly utilizes the sublimation phenomenon under low temperature and vacuum environment. That is, the freshly pretreated tea is cryogenically frozen to form ice crystals in the tea. Then, under the vacuum environment, by controlling the temperature and adjusting the vacuum degree, the ice crystals are directly converted into water vapor, thereby realizing the dehydration process of the tea.

[0003] Inside the freeze-drying chamber, the tea is placed on a bracket. After freeze-drying is completed, the chamber door is opened, and then the bracket is pulled outwards to take out the tea, as Figure 1 shown. Since multiple portions of tea need to be freeze-dried at one time, the brackets inside the freeze-drying chamber are divided into multiple layers, which requires manual pulling out layer by layer when taking out, which is rather troublesome.

Detailed Embodiments

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0021] The freeze-drying chamber for tea dehydration provided in this specific embodiment is as Figure 2 , Figure 3 and Figure 5 shown, and includes a main body member and an improved member, where:

[0022] The main body member includes a freeze-drying chamber 1. A chamber door 3 is provided on the front of the freeze-drying chamber 1. The bottom ends of the chamber door 3 and the freeze-drying chamber 1 are both connected to a bottom support 2. There are a total of six bottom supports 2, four at the four corners of the bottom of the freeze-drying chamber 1 and two at the two corners of the bottom end of the chamber door 3. And the bottom ends of the bottom supports 2 on the chamber door 3 are above the bottom supports 2 on the freeze-drying chamber 1, that is to say, the bottom supports 2 on the chamber door 3 are higher than the bottom supports 2 on the freeze-drying chamber 1.

[0023] The improved structure includes guide rails 4 symmetrically connected to both sides of the inner wall of the freeze-drying chamber 1 and distributed along its width direction. A rectangular frame 5 is slidably connected between the two guide rails 4. A fixing mechanism 6 for fixing the two is provided between the rectangular frame 5 and the chamber door 3. Specifically, as Figure 6 shown, the fixing mechanism 6 includes a screw hole 601 opened on the front of the rectangular frame 5; at the same time, a through hole 602 corresponding to the screw hole 601 is penetrated through the chamber door 3. A bolt 603 is movably passed through the through hole 602. The bolt body of the bolt 603 is cooperatively connected into the screw hole 601. And a bracket 7 is placed in the rectangular frame 5. Blocks 8 are connected to the front and back of the bracket 7 and are propped on the top end of the rectangular frame 5; in addition, a driving mechanism 9 for driving the bottom support 2 on the chamber door 3 to translate along the direction of the guide rail 4 is further provided on the bottom support 2 of the freeze-drying chamber 1. As Figure 4 shown, the driving mechanism 9 includes a cylinder 901 fixed between the bottom supports 2 and parallel to the guide rail 4. The fixed end of the cylinder 901 is fixed to the inner side of the rear bottom support 2 on the freeze-drying chamber 1. The telescopic end of the cylinder 901 movably passes through the front bottom support 2 on the freeze-drying chamber 1 and is fixed to the inner side of the bottom support 2 on the chamber door 3. In this way, the bracket 7 is propped in the rectangular frame 5 through the blocks 8, and the rectangular frame 5 and the chamber door 3 are fixed. Thus, under the action of the driving mechanism 9, the bottom support 2 on the chamber door 3 can be driven to drive the chamber door 3, the rectangular frame 5 and the bracket 7 to move outwards together, so that all the brackets 7 can be moved out of the interior of the freeze-drying chamber 1 together. In this way, it is not necessary for the staff to take out the brackets 7 layer by layer.

[0024] As Figure 5As shown, the reason why the rectangular frame 5 can slide is that a chute 10 of the same length as it and distributed along the width direction of the freeze-drying chamber 1 is provided on the inner side of the guide rail 4. A slide bar 11 of the same length as it and fixed to the side surface of the rectangular frame 5 is slidably connected in the chute 10. In addition, a limiting mechanism 12 for restricting the separation of the back surface of the slide bar 11 from the front surface of the chute 10 is provided between the two. The limiting mechanism 12 includes a limiting groove 1201 provided at the top of the guide rail 4, which is communicated with the chute 10 and parallel to it, and the front surface of the limiting groove 1201 is not communicated with the guide rail 4. At the same time, a limiting block 1202 slidably connected with the limiting groove 1201 is connected to the top of the slide bar 11 near its back surface. Through the action of the limiting block 1202, the rectangular frame 5 can be prevented from separating from the guide rail 4.

[0025] In addition, it is worth mentioning that a force-applying groove is penetrated through the part of the stopper 8 that protrudes from the bracket 7, so that the stopper 8 is configured to form a handle structure. The stopper 8 has two functions. One is to place the bracket 7 in the rectangular frame 5 to prevent it from falling. The other is to facilitate holding it to take out the bracket 7.

[0026] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0027] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
