DBS Series Disc Stack Centrifuge
The DBS Series variable slagging centrifuge designed by Jiangsu Sadelis is mainly used for the collection, clarification of yeast and bacteria, as well as the separation of crushed liquid of yeast and bacteria and other bacterial liquids. It provides a separation system with a CIP (Clean-in-Place) automatic cleaning program, enabling fully automatic CIP cleaning while completing production tasks. It is particularly suitable for pilot-scale products and the initial stage of small-capacity production, helping high-value-added biopharmaceutical products achieve rapid commercialization.
Main Features
- Fast speed, high separation factor, large equivalent sedimentation area, and strong separation capacity.
- The reliable variable slagging mechanism can control the feeding time to adjust the slagging amount per cycle. The concentration of discharged solids is maintained at a high and uniform level, with a stable and reliable structure that reduces the risk of blockage.
- The equipment module offers two operating modes: manual and automatic, and can operate automatically according to the set parameters.
- Parts in contact with products are made of stainless steel, adopting advanced surface treatment technology, with a surface finish of 0.4 m [optional].
- Sealed drum structure, better meeting the requirements of the food and beverage, biochemistry, and pharmaceutical industries.
- It can realize automatic online CIP, improving production efficiency and reducing labor intensity.
- The main sealing ring is made of high-strength polymer material instead of traditional nylon material, which extends the service life of the main sealing ring and saves the machine's operating costs.
- Seals in contact with materials comply with FDA (U.S. Food and Drug Administration) regulations. The entire machine meets GMP (Good Manufacturing Practice) standards.
