Microsphere Screen

Microsphere Screen
【Material Requirements】:Used in the biopharmaceutical field for solid–liquid separation of microspheres
【Product Overview】:The Navector Microsphere Sieve is specially designed for medical and cosmetic microsphere screening, integrating filtration, washing, and drying in one system. It separates materials using centrifugal and negative-pressure fluid methods and employs ultrasonic vibration for efficient drying without the need for mechanical stirring. The solids are collected and stored as dry, free-flowing, non-caking powders.
Product Introduction
Principle Introduction
In the process of microsphere preparation, vibration screening is a key step in achieving material particle size separation. Through vibration screening, materials with different particle sizes can be effectively separated to ensure that the particle size distribution of microspheres meets quality standards.The power of the vibrating screen comes from the vibration motor.The vibration motor generates a composite inertial force through eccentric blocks of different phases at the upper and lower ends. This force is generated by the high-speed rotation of the vibration motor, forcing the vibrating body of the screening machine to make circular motion.
Equipment Advantages
- On site cleaning
After the production of the equipment is completed, the screen mesh is removed for ultrasonic cleaning, and the interior of the equipment is cleaned comprehensively through the built-in spray ball. The cleaning process fully meets the requirements of ASME-BPE, with no dead corners and full coverage.
After the internal cleaning of the equipment is completed, install the cleaned mesh to prepare for the next step of steam sterilization (SIP).
- on-site steam
After on-site cleaning is completed, all components of the equipment are installed and reset, and online sterilization is carried out through the steam sterilization tube on the feeding port. During the sterilization process, the discharge valve (cylinder body) remains open.
- Vibration drying technology
Nitrogen vibration drying: The vibration generated during equipment operation combines with nitrogen to remove excess moisture from the material, achieving a drying effect.
Control and Efficiency: All drying processes can be adjusted through a control box, making it easy to operate. The drying process is efficient and does not require intermediate transfer or processing steps.
Vacuum and temperature control: Set the indoor vacuum level to medium to optimize drying conditions.
Homogeneous drying process: The material is evenly distributed on the sieve under the action of vibration.
Applications
This product is primarily used in the biopharmaceutical field for solid–liquid separation of microspheres. It allows for batch filtration, washing, dewatering, and drying, all within a sealed system, eliminating the need for intermediate transfer.
