AI Technical Summary
During the lyophilization process, elastic biomaterials such as the pericardial and submucosal tissue of the small intestine are uneven, causing wrinkles, unevenness or too thickness in the finished product after lyophilization, which affects product performance and use. Flattening with a press plate will affect the sublimation of the biocollagen membrane and water vapor escape.
An elastic biomaterial freeze-dried mold including a first template, a limiting ring, a second template, a threaded rod and a pressure plate is designed to increase the contact area between the material and the air by the arrangement of the grooves and through holes, and to achieve a flat fixation of the material by the coordination of the threaded rod and the pressure plate.
By increasing the contact area between the material and the air and smoothing treatment, the lyophilization speed is improved, ensuring that the product is smooth and wrinkle-free after lyophilization, and improving product performance and usage effect.

[0003] When freeze-drying elastic biological materials such as bovine pericardium and small intestinal submucosa tissue, if these tissues are uneven before being put into the freeze-dryer, the freeze-dried products will have wrinkles, unevenness, or even excessive thickness, which will affect the performance and use of the products; if a pressing plate is used to flatten the elastic biological materials during the freeze-drying process, it will affect the sublimation of the biological collagen membrane and the escape of the water vapor released by desorption, thus affecting the freeze-drying effect of the biological collagen membrane. Therefore, it is necessary to design and transform the freeze-drying mold for elastic biological materials to effectively prevent the phenomenon of inconvenient use. Summary of the Utility Model
