Sterile grade rake vacuum dryer

The aseptic rake dryer is a multi-functional, fully sealed vacuum drying equipment that integrates drying and mixing. It is suitable for the production of aseptic products in the pharmaceutical industry. It is mainly used for the drying and mixing of powders with high hygiene requirements such as antibiotics, apis, and fine chemicals. To ensure complete isolation between the process area and the technical area, the HPG type aseptic rake dryer adopts a horizontal wall-penetrating installation method, fundamentally avoiding contamination to the products.

The working principle of aseptic vacuum paddle dryer

The aseptic rake dryer is an economical and powerful multi-purpose equipment suitable for large-scale production. It is suitable for use as a mixer, reactor or dryer, and can be designed to operate under vacuum or pressure as required. By heating the tank wall, head, stirring shaft and stirring paddle, the heating area is very large, resulting in particularly good heat transfer efficiency. The shaft seal can adopt a stuffing box and can also be interchanged with double-end face wet, dry or non-contact mechanical seals. Due to the very small gap between the stirring paddle and the tank wall as well as the special design of the stirring paddle, the discharge performance is excellent. The cGMP and FDAHDS type vacuum paddle dryer is suitable for the production of sterile products in the pharmaceutical industry, including: a quick-opening flat head; A special cantilevered installation agitator with a heated agitator paddle on top; A double-end face mechanical seal; A dust collector; A discharge valve installed at the bottom or a piston-type discharge valve installed on a flat head.

Performance features of aseptic vacuum paddle dryer

(1) It has excellent sealing performance and high cleanliness. All sealing elements are made of materials that meet GMP requirements.

(2) No foreign matter contamination: A special mechanical seal is used between the stirring shaft and the cavity to ensure that the product is free from contamination by lubricating oil and other foreign substances, meeting the requirements of aseptic production.

(3) High thermal efficiency: All surfaces in contact with the material are heated, such as the tank body, rear head, front head, agitator and dust collector. Uniform heating is provided, and the heat exchange area is large, which can provide high heat exchange efficiency.

(4) Excellent drying effect: The heated stirring shaft not only exchanges the inner and outer layers of the material but also effectively prevents the material from adhering to the wall and forming lumps, thus facilitating drying and improving the quality of the dried material.

(5) The quick-opening flat head is easy to open for cleaning and verification. The discharging, sampling and unloading are smooth with less residue.

(6) Double-end face wet, dry or non-contact mechanical seals are suitable for the production of sterile products.

(7) Equipped with CIP cleaning and SIP in-place high-temperature sterilization systems, it can achieve processing and conversion of different products in a short time.

(8) Comply with cGMP and FDA;
