How can Revtech eradicate pathogens and preserve the qualities at the same time? >Read more

Heat and steam are required for pasteurization. To preserve the organoleptic properties, Revtech perfectly controls the process:

  • Perfect homogeneity of treatment – mixing is very efficient as every particle progresses along the spiral with about 4000 jumps. This way every particle is treated, no particle is over treated.

  • Very small amount of steam is used – the particles are first heated by the contact with the hot spiral and only around 5% of steam is injected at the end of the process to complete pasteurization.

 

 Benefits for your factory

  • Low energy consumption: ~ 80 kW.h for 1 ton of product ie. less than 0,01€/kg.
  • Cleaning is vastly simplified (about 1 to 2 hours) using CIP techniques and/or pyrolysis. There are no dead zones in the machine, which consists of one continuous smooth stainless steel pipe.
  • No dust extraction equipment required: a direct exhaust to the atmosphere is sufficient.
  • Robust technology and negligible maintenance costs.
  • Continuous and fully automated process requiring little operating personnel (1 person can run the complete line).
