Solid liquid separator Solid-liquid separation part

Solid liquid separation: It refers to the separation and removal of suspended solids in fermentation liquor (or culture liquor), such as precipitates of cells, bacteria, cell fragments and proteins, or their flocs.

I Solid liquid separation equipment

1. Filter equipment

Principle of plate and frame filter

Features The plate and frame filter press has a large filtering area, can withstand a high pressure difference, and has strong adaptability to different filtering characteristics. At the same time, it has the advantages of simple structure, low cost, and low power consumption. However, this kind of equipment cannot be operated continuously. It is bulky, occupies a large area, and takes a long time for non production assistance (including unfreezing, cake unloading, filter cloth washing, and re pressing the plate and frame).

Applicable objects are widely used in the filtration of culture medium preparation and the filtration of various fermentation liquids such as molds, actinomycetes, yeasts and bacteria.

2. Centrifugal equipment

Filter type Centrifuge

Small holes are opened on the drum, and the inner surface of the drum is covered with filter media. Under the action of centrifugal force, liquid flows through the filter media through the holes, and solids are trapped on the surface of the filter media. It is mainly used to deal with occasions with large solid particles and high solid content in suspension.

Sedimentation centrifuge

There is no small hole on the drum, and no filter medium is needed. Under the action of centrifugal force, solids settle on the drum wall, and the rest is clear liquid. It is suitable for occasions with low solid content (less than 10%). The commonly used sedimentation centrifuges are disc centrifuges and tubular centrifuges.
