Since 1980 Mavi delivers Viproc instant coffee coolers as a fluidized bed system. The equipment is quite simple: a vibrating trough with a perforated plates bed and a hood for capturing the fines is vibrated and a steady air flow passed through.
Depending on the time remaining on the bed and the air volume blown in to the system, more or less heat can be absorbed.
Viproc heaters and coolers are in use in many applications. For coffee, dog food, foundry sand, plastic pellets and many others. Call Mavi if you need help with fluidized bed coolers and heaters.
