中试设备测试装置 膜过滤中试设备

结合了螺旋型和板框式膜过滤的中试设备

通过操作员面板的 PLC 并仔细选择现场仪器和控制阀,使用中试装置进行的长期测试可以准确地显示关键工艺参数。与手动控制中试装置相比,这对大规模测试来说是一个极大的优势。

膜设计

探索可用的螺旋型膜配置,找到最适合您的工艺要求的解决方案:

  • 微滤
  • Ultrafiltration

The area of the spiral wound membrane ranges from approx. 3‐7 m2 depending on membrane brand, type and thickness of the feed spacer.

The P&F loop is configured with 2.25 m2 membrane area in one section.

System design

  • Aimed at ultrafiltration of viscous (fermented) products
  • Two loops; loop 1 with two parallel 3.8” spiral wound membranes. Loop 2 is a P&F module with positive displacement pump. The loops can be operated in series or individually
  • Suitable for e.g. quark, cream cheese, protein standardization
  • Includes mixer for uniform feed inlet and retentate cooler for improved product quality
  • The product solids are regulated by ratio control
  • Feed inlet flow ranges: 100 – 400 lph

The control panel provides automatic continuous control of various process parameters and allows selection between different control modes:

  • Feed flow
  • Feed pressure
  • Temperature
  • Concentrate ratio control
