Embodiment 1

[0041] figure 1 An embodiment of a drying apparatus for biological materials is shown, in combination with figure 2, including a load-bearing structure 1 and a pressure-applying structure 2 for fixing the biological material through mutual snap-fit. The bearing structure 1 has a plurality of first bearing parts 11 protruding from the bearing surface; the pressing structure 2 has a plurality of groove bodies 21 which are recessed away from the pressing surface, and the groove bodies 21 are identical to the first bearing parts 11 . A corresponding arrangement is provided, and the depth of the groove body 21 is smaller than the length of the first bearing portion 11 protruding from the bearing surface. An airflow gap is formed between the bearing surface and the pressing surface, which facilitates the passage of airflow of the biological material during the ventilation and drying process, so that the drying degree of the biological material is more uniform. In order to increas...

Embodiment 2

[0049] The drying method of biological materials in the prior art is generally that biological materials such as biological amniotic membrane and collagen membrane are directly placed on a tray in an electric heating blast drying box to dry, during which the biological materials shrink due to drying, forming an uneven membrane. The use of a simple jig will result in uneven drying of the biological material. Alternatively, the above-mentioned biological material is flattened, and the periphery of the biological material is fixed on a plate-like device. Because of its fixed point of force around the periphery, the biomaterial shrinks when it dries and is prone to tearing in the middle. In addition, after the biological material is dried, patterns such as patterns need to be pressed on it, and processing such as cutting, packaging, sterilization, etc. is required, but the simple method of using copper stamping and steel stamping will not only bring unnecessary pollution or damage...

specific Embodiment approach

[0055] Another specific embodiment of the drying method of biological material, comprises the following steps,

[0056] The collagen membrane material that has undergone washing, cross-linking and other steps is laid flat on the bearing surface of the bearing structure 1, and the groove body 21 of the pressure applying structure 2 and the first bearing part 11 of the bearing structure 1 are held in one-to-one correspondence with each other. Load the positioning nitrate, or clip into other positioning devices, and the collagen membrane material is clipped between the bearing structure 1 and the pressure-applying structure 2. Since the length of the first bearing portion 11 protruding from the bearing surface is greater than the depth of the groove body 21 , there is an airflow gap for air to pass between the bearing surface and the pressing surface. Place the drying equipment on which the collagen film is placed in an electric heating blast drying oven (Boxun GZX-9023MBE), dry ...

Abstract

A drying equipment and a drying method for biological materials, which relate to the technical field of drying equipment, include a bearing structure and a pressure-applying structure for fixing biological materials by mutual snap-fit; The pressure-applying structure has a plurality of grooves that are recessed away from the pressure-applying surface, the grooves and the first bearing part are arranged in a one-to-one correspondence, and the depth of the grooves is less than the length of the first bearing part protruding from the bearing surface, and the external force acts When the lower first bearing part is clamped with the tank body, an airflow gap will be formed between the bearing surface and the pressing surface, which facilitates the passage of airflow, makes the drying degree of the biological material more uniform, and at the same time ensures that the activity of the biological material is not affected. In addition, the biomaterial is uniformly stressed, avoiding shrinkage during drying and causing deformation or tearing, ensuring the integrity of the biomaterial after drying.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a drying equipment and a drying method for biological materials. Background technique [0002] Most of the current biological materials, such as biological amniotic membrane and collagen membrane, are dried by freeze-drying, drying or microwave drying. Some of the above methods will use organic solvents such as DMSO, glycerol, or auxiliary solvents such as sucrose to stabilize biological materials during the freeze-drying process and reduce the damage of ice crystals to biological materials. influences. However, simple oven drying or simple freeze drying will cause uneven drying of the material, shrinkage or adhesion to the drying equipment; at the same time, since the biological material is usually flattened and fixed around the plate material, so Biomaterials tend to shrink when drying, causing tearing in the middle. SUMMARY OF THE INVENTION [0003] Therefore, th...
