Description

Technical Field

[0001] This utility model relates to the technical field of freeze dryer plate and layer equipment, specifically to a freeze dryer plate and layer structure and a freeze dryer. Background Technology

[0002] The freeze dryer plate is a key component, primarily used to hold the materials to be freeze-dried, transferring heat and ensuring the smooth completion of the freeze-drying process. During operation, the cooling medium enters the inner cavity of the plate to achieve a cooling effect. Typically, a guide plate is installed within the inner cavity to guide the flow of the cooling medium, ensuring temperature uniformity across the plate. In existing technology, the plate consists of an upper panel, a lower panel, a guide plate, and a sealing plate. The guide plate, positioned between the upper and lower panels, serves to guide the cooling medium and reinforce the structure. However, the inventors have discovered that current freeze dryer guide plates are mostly flat structures. While they can organize the cooling medium, they lack control over its flow rate, resulting in a relatively fast flow rate within the plate and hindering the efficient transfer of low temperatures to the plate. Therefore, this invention proposes a freeze dryer plate structure and a freeze dryer in general. Utility Model Content

To address the drawbacks and defects described in the background art, this technical solution includes the following:

The freeze-drying plate layer 2 includes a lower plate 21 and an upper plate 22 located above the lower plate 21, as well as a barrier frame 23 fixed to the upper surface of the upper plate 22. A cooling medium limiting component 3 is provided between the lower plate 21 and the upper plate 22.

[0029] The cooling medium limiting assembly 3 includes an inlet groove 36 fixed on the left side of the inner cavity of the lower panel 21 and an outlet groove 34 fixed on the right side of the inner cavity of the lower panel 21. Nine to twelve hollow serpentine tubes 31 are fixedly connected at equal distances on the side of the outlet groove 34 and the inlet groove 36 that are close to each other. The hollow serpentine tubes 31 form nine to twelve serpentine chambers 35 between each other.

[0030] Multiple liquid inlets 37 located in the serpentine chamber 35 are provided on the end face of the liquid inlet tank 36 near the liquid outlet tank 34. Multiple liquid outlets 33 located in the serpentine chamber 35 are provided on the end face of the liquid outlet tank 34 near the liquid inlet tank 36. Cooling medium flows inside both the hollow serpentine tube 31 and the serpentine chamber 35.

[0031] The lower panel 21 and the upper panel 22 have cavities between them for the cooling medium limiting component 3 to be accommodated; the upper and lower surfaces of the liquid inlet tank 36, the upper and lower surfaces of the liquid outlet tank 34, and the upper surface of the hollow serpentine tube 31 are respectively fixedly connected to the side end faces of the lower panel 21 and the upper panel 22 that are close to each other.

[0032] One-way connectors 32 are installed on the right end faces of both the liquid outlet tank 34 and the liquid inlet tank 36.

The serpentine chamber 35 is connected to the internal space of the liquid outlet tank 34 and the liquid inlet 37 through the liquid outlet 33 and the liquid inlet 37, respectively.

[0033] The material to be freeze-dried is placed on the upper surface of the upper panel 22.

[0034] A preferred technical solution for a freeze dryer includes a freeze dryer device 1, which includes a body 11, a freeze drying chamber 12 fixed to the upper layer of the inner cavity of the body 11, and multiple sets of shelves 14 fixed at equal intervals on the left and right side walls of the inner cavity of the freeze drying chamber 12, with freeze drying plates 2 arranged at equal intervals on the shelves 14.

At this time, the low-temperature cooling medium will enter the liquid inlet 36 along the one-way connector 32 on the liquid inlet 36 and simultaneously enter the serpentine chamber 35 along the liquid inlet 37. Another part of the medium will enter the hollow serpentine tube 31. The serpentine chamber 35 and the hollow serpentine tube 31 act as channels, forcing the medium to flow in a serpentine manner inside the lower panel 21 and the upper panel 22. The hollow serpentine tube 31 and the serpentine chamber 35 slow down the flow rate of the medium, so that the material above the upper panel 22 can be fully frozen.
