Machines for the processing of collagen

Colloid mills from Probst & Class for processing collagen 

Colloid mills are used both in the extraction of collagen from animal tissues and in their processing. As in other applications in the processing industry, colloid mills are used to grind materials finely and to emulsify, disperse and homogenise different phases.

Raw materials used in processing collagen 

• Raw collagen - from animal tissues (skin, bones, tendons, etc.)
• Water - for pretreating and extracting collagen from the raw material.
• Process-supporting chemicals: acids and bases support the remodelling and extraction of the raw collagen.

Collagen-processing procedure

The pretreated collagen solution is fed into the colloid mill. The collagen is further comminuted by mechanical shear, pressure and frictional forces, which is important for the fineness and consistency of the collagen particles.

The processing of collagen is normally limited to a maximum temperature, as otherwise the proteins begin to deteriorate. For this reason, we offer special double-walled housings and funnels for better temperature control in the processing of collagen.

Filtration and purification: Collagen is often filtered and purified to remove unwanted particles and impurities after processing in colloid mills. Concentration and drying: Purified collagen is concentrated and dried to obtain collagen powder. PUC does not offer its own machines for these final steps, although we will be happy to advise you on the selection of a suitable supplier.

Typical end products

Typical end products for the pharmaceutical industry are wound healing products, collagen injections and joint supplements.

Typical end products for the cosmetics industry include skin creams, anti-ageing products and hair and beauty products.

In-line or batch operation

Processing and production can be carried out in Probst & Class mills and systems in a batch process or in a continuous in-line process, depending on requirements. We also offer in-line deaeration systems for the extraction of air or other gases. This step is particularly beneficial before packaging in order to achieve a clean environment and optimise the properties of the product. We will be happy to advise you as to the advantages and disadvantages of the processes and of system integration. Please send us an enquiry for our PUClab service.
