Description

Technical Field

[0001] This utility model relates to the field of freeze dryer technology, and in particular to a compact integrated freeze dryer. Background Technology

[0002] Freeze-drying is a drying technology that utilizes the principle of sublimation. It involves rapidly freezing the substance to be dried at low temperatures, and then, in a vacuum environment, causing the frozen water molecules to sublimate directly into water vapor and escape. Freeze dryers operate based on this principle. With technological advancements and rising living standards, freeze dryers have gradually shifted from large commercial machines to smaller household models. However, size remains a critical issue for household models. Currently, most freeze dryers consist of heating tubes wrapped around the outside of a vacuum chamber, heating the entire chamber through these tubes. However, this structure occupies a significant amount of space, and the heat transfer process involves multiple media, resulting in substantial losses. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a compact, integrated freeze dryer with high heat transfer efficiency, a more compact structure, and a smaller size.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] 2. A compact integrated freeze dryer, comprising a housing, wherein a vacuum chamber, a vacuum pump, and a compressor are provided within the housing, characterized in that: a freeze-drying chamber and a cold trap are provided within the vacuum chamber, the freeze-drying chamber is located above the cold trap and communicates with the cold trap, a heating device is provided on the freeze-drying rack in the vacuum chamber, the compressor is connected to the condenser tube in the cold trap, and the vacuum pump is connected to the vacuum chamber.

[0006] In the above technical solution, the vacuum chamber, vacuum pump and compressor are all mounted on the bottom plate of the housing, and the vacuum pump and compressor are mounted on one side of the vacuum chamber.

[0007] In the above technical solution, a partition is provided between the freeze-drying chamber and the cold trap, and an air inlet is provided on one side of the partition.

[0008] In the above technical solution, the freeze-drying rack is provided with multiple layers of shelves, and the heating device is a heat-conducting coil set at the bottom of the shelves.

[0009] In the above technical solution, the vacuum chamber door is mounted on the shell, and a control panel is located on one side of the shell near the door.

[0010] In the above technical solution, the vacuum pump and the compressor are arranged sequentially along the radial direction of the vacuum chamber.

[0011] In the above technical solution, a condenser is connected to the compressor.

[0012] In summary, the advantages of this utility model compared to traditional technologies are as follows: This utility model employs a novel heating structure, with the heating device directly installed at the bottom of the freeze-drying rack, directly heating the materials on the rack, effectively saving space and reducing heat transfer loss.

[0013] Furthermore, by integrating the existing structure of the freeze dryer, the internal structure relies on the vacuum chamber design, with the cold trap installed at the bottom of the freeze drying chamber, and the vacuum pump and compressor installed on the bottom plate on the side of the vacuum chamber, making the entire freeze dryer more square and suitable for home use, and greatly reducing the size of the freeze dryer.
