Custom Vacuum Freeze-Drying Machine Air Sealing Rings? Look to Qingtu Rubber - Specialized in...Inflatable sealing ringR&D and Production

Vacuum Freeze Drying Machines are suitable for drying heat-sensitive or easily oxidizable pharmaceuticals, commonly known as lyophilizers, and mainly consist of a lyophilization chamber, vacuum system, heating system, and refrigeration system. They can be categorized by tray area into small-scale laboratory lyophilizers, medium-sized production lyophilizers, and large-scale industrial production lyophilizers. Many dry raw drugs and formulated drugs with lyophilizers. The main requirements are high reliability, comprehensive sterilization functions, and a temperature difference between the trays and between layers not exceeding 1.5°C, which necessitates good flatness of the trays. To ensure product uniformity when drying raw drugs with this equipment, it is advisable to add a mixing blender. Aminopenicillin, large quantities of blood products, artificial cultured drugs, antibodies, vaccines, and many others commonly use lyophilizers.

With the process of reform and opening up, the pharmaceutical industry has developed rapidly, and the pharmaceutical machinery industry has also presented a flourishing situation. Due to my work, I have had the opportunity to apply the above-mentioned drying equipment. However, due to limited exposure, many excellent dryers, such as disk dryers, fluidized bed dryers, flash drying equipment, and microwave series dryers, have not been introduced. When selecting a dryer, one should consider the characteristics of the drug and the desired finished product state, especially the material and sterile guarantee of the drying equipment for sterile active pharmaceutical ingredients. China's pharmaceutical drying equipment industry has developed rapidly, with a large number of professional drying equipment manufacturers. Their products are both versatile and have unique features, providing conditions for the domestication of imported equipment used for drying active pharmaceutical ingredients and the selection of ideal dryers that comply with the Good Manufacturing Practices (GMP) for drug production.
 

Product Advantages:

Utilizes imported inflatable high-density sealing strips for superior sealing performance.

Stainless steel round observation window.

Interlocked to prevent incorrect operation.

The door frames feature a matching stud design for easy installation.

The door panels feature a concentric circle design at the corners for enhanced airtightness.

This inflatable silicone rubber sealing ring and its sealing structure feature simple design, easy installation, excellent sealing performance, and the capability of achieving self-sealing in both axial and radial directions. The outer edge of the inflatable sealing ring is equipped with a guiding positioning ring, and when the upper and lower lips on the inner edge are closed together, they form a complete hollow circular ring. Once the hollow ring is filled with high-pressure gas (or liquid) inside the pressure vessel, it expands outward, generating self-tightening properties in both axial and radial directions. The greater the internal pressure of the pressure vessel, the stronger the self-tightening effect, and the better the sealing performance.
