Collagen peptides

Hydrolyzed collagen has been used during cooking for over 100 years. Collagen peptide powder is used in meats, fish and for protein enrichment in all types of food because of its functional properties. 85 to 90% protein is obtained with a high level of functionality.

Hydrolyzed collagen is notoriously difficult to handle in wet feed, slurry or cake, exhibiting poor flow characteristics and a cohesive tendency. It is also temperature sensitive. When these difficulties are added to the demand for end products of the right colour and taste it becomes clear that it is critical to select the right dryer.

Hosokawa's Drymeister (DMR-H) flash drying system has proved to be highly successful in drying collagen peptide slurries, achieving considerable savings in processing costs when compared to other typical drying equipment.

Typical requirements

  • Moisture content product: generally up to 6%
  • Product temperature: < 80 °C
  • Particle size distribution: fine powder, no agglomerates
  • Raw material: slurry with a moisture content of approx. 70%

Drying and milling process

The above diagram clearly shows that the number of process steps (and therefore operational cost) is reduced when using a Drymeister (DMR-H) flash dryer. By design, the Drymeister requires less thermal energy per kilogram of evaporated water than conventional dryer, resulting in further savings and a more environmentally friendly operation.

Special strong milling section

The milling section in the bottom part of the dryer is designed to give optimal grinding of the wet material. Products obtained from a traditional dryer contain unwanted agglomerates, thus requiring additional milling after drying. This is an additional process step which the Drymeister does not require.

Drying & classifying in one step

Combining several unit operations in the dryer simplifies the process and reduces operational cost. With the introduction of the Drymeister (DMR-H) flash dryer even the most difficult products can be very efficiently dried and classified in one step to a fine and uniform product.
