Description

Technical Field

[0001] The utility model relates to the technical field of vacuum drying, and more specifically to a heat exchange plate of a freeze drying machine. Background Art

[0002] The working principle of the vacuum freeze dryer is to freeze the product first, and then provide appropriate sublimation heat in a vacuum environment to convert the water or solvent in the frozen product into water vapor or vapor vapor to achieve the purpose of dehydrating the product. Among them, the freezing and sublimation process of the product is carried out on the heat exchange plate in the drying box. The product is generally freeze-dried by loading vials or trays. No matter which method is adopted, the temperature on the surface of the heat exchange plate must be uniform.

[0003] The prior art discloses some patent documents of heat exchange plates of freeze dryers. The Chinese patent with application number CN202122789596.6 discloses a heat exchange plate of a vacuum freeze dryer, including an upper plate, a lower plate, a movable press seat, a fastening bolt and a slide rod. The upper plate and the lower plate are each provided with a serpentine flow groove on the inner side, and the two sides of the serpentine flow groove are respectively provided with mounting grooves for installing a guide hose. The upper plate and the lower plate are each provided with a first perforation near both ends, and the outer wall of each plate is provided with a positioning slide groove near both ends, and one end of the positioning slide groove extends to the long side of the plate body. The movable press seat includes a slip ring, a press plate and a positioning convex ridge. The outer side of the slip ring is symmetrically provided with two mutually parallel press plates, the press plate is provided with a second perforation, and the inner side of the press plate is provided with a positioning convex ridge. The utility model has a reasonable structural design, and its unit template has fewer components, and the production process is relatively simple, which is convenient for industrial mass production; it can be combined and used through the guide assembly component composed of the movable press seat and the slide rod to better meet the use requirements.

[0004] In the above patent, when fixing the upper and lower plates, they are directly fixed by bolts, and the bolts are easily corroded on the outside, which makes it difficult to remove the bolts. For this reason, we propose a heat exchange plate for a freeze dryer. Utility Model Content
