Embodiment 1

[0041] figure 1 Shown is a specific implementation of the drying equipment for biological materials, combined with figure 2, including a bearing structure 1 and a pressure-applying structure 2 for fixing biological materials through mutual snap fit. The bearing structure 1 has a plurality of first bearing parts 11 protruding from the bearing surface; the pressure applying structure 2 has a plurality of recessed grooves 21 far away from the pressure applying surface, and the grooves 21 are integrated with the first bearing parts 11. One corresponding setting, and the depth of the groove body 21 is less than the length of the first bearing part 11 protruding from the bearing surface, so that when the first bearing part 11 and the groove body 21 are clamped by an external force, An airflow gap is formed between the bearing surface and the pressing surface, which facilitates the passage of airflow during the ventilation and drying process of the biological material, so that the ...

Embodiment 2

[0049] The drying method of biological materials in the prior art is generally to place biological materials such as amniotic membrane and collagen membrane directly on a tray in an electric blast drying oven for drying, during which the biological materials shrink due to drying and form an uneven film. Using simple clamps can result in uneven drying of the biological material. Alternatively, the above-mentioned biological material is leveled, and the surroundings of the biological material are fixed on the plate-like device. Due to its fixation points around, the biological material shrinks when drying, and it is easy to tear in the middle part. In addition, after the biological material is dried, patterns such as patterns need to be pressed on it, and then processed by cutting, packaging, and sterilization. In addition, the patterns such as the pressed pattern will gradually flatten or even disappear with the passage of time due to the toughness of the biological material. ...

specific Embodiment approach

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

[0056] Lay the collagen membrane material that has been processed through steps such as washing and cross-linking on the bearing surface of the bearing structure 1, and clamp the groove body 21 of the pressure applying structure 2 and the first bearing part 11 of the bearing structure 1 in one-to-one correspondence, Put it into the positioning tool, or snap into other positioning devices, and the collagen membrane material is stuck 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 between the bearing surface and the pressing surface for air to pass through. Place the drying equipment with the collagen film in an electric blast drying oven (Boxun GZX-9023MBE), and dry it for 8 hours at a tem...

Abstract

The invention relates to the technical field of drying equipment, in particular to drying equipment and a drying method for biological materials. The drying equipment comprising a bearing structure and a pressure applying structure which are clamped and matched with each other to fix the biological materials; the bearing structure is provided with a plurality of first bearing parts protruding out of the bearing surface; the pressure applying structure is provided with a plurality of grooves which are concavely arranged away from a pressure applying surface, the grooves and the first bearing parts are arranged in a one-to-one correspondence mode, the depth of the grooves is smaller than the length of the first bearing parts protruding out of the bearing surface, and when the first bearing parts and the grooves are clamped under the action of external force, airflow gaps can be formed between the bearing surface and the pressure applying surface, so that airflow can pass through conveniently, the drying degree of the biological materials is more uniform, meanwhile, the situation that the activity of the biological materials is not affected is ensured, and in addition, the biological materials are evenly stressed, deformation or tearing caused by shrinkage in the drying process is avoided, and the integrity of the dried biological materials is guaranteed.

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, oven-drying or microwave drying. Some of the above methods will use organic solvents such as DMSO, glycerin, 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. The use of these solvents will cause certain effects on the activity of biological materials. influences. The simple use of oven drying or simple freeze-drying will cause uneven drying of the material, shrinkage or adhesion on the drying equipment; at the same time, because the biological material is usually flattened and fixed around the plate-shaped material, so Biomaterials...
