  • 1 Rotoform unit with a belt width of 1500mm and cooling length of 15m – for as rental unit for the temporary installation at customer sites
  • 1 Double Belt Cooler unit with a belt width of 600mm and cooling length of 5m – for in-house trials and also as rental unit for the temporary installation at customer sites
  • 1 Precrystallization unit for sub cooled liquids – for in-house trials and also as rental unit for the temporary installation at customer sites
  • 1 Inline mixing device to mix solids with liquids before solidification

For prototype testing and product development

  • 1 Rotoform unit with a belt width of 1500mm and cooling length of 5m – for full scale prototype in-house testing as a last part of the product development process

Auxiliary equipment

In order to accommodate various process conditions we have auxiliary equipment which can be assembled for each trial according to the customer needs

  • Different types of release agent application systems
  • Different types of casting devices for the flaking process like overflow weir, casting box or calendar feeding rollers
  • Different types of discharge devices to select the most suitable for the process
  • Different types of breakers for the flaking process
  • Thermocut system to optimize pastille shape of high viscous products
  • Air handling unit to be able to use cold air from the top in addition to cooling water to increase solidification capacities
  • Pumps: centrifugal pumps, gear pumps, piston pumps, heated and unheated
  • Jacketed product vessels from 8 liters up to 300l volume
  • Agitators with low shear force and high shear force as required
  • Remelter to melt the customer product before usage
  •  Valves, jacketed piping spools, instruments to be connected with the required equipment to have the right test set up.
  • 5 separate heating units to generate the right temperature for the jacketed equipment
  • Steam generators, in case steam is used for heating
  • Chiller units to create the right cooling water temperature, if cold temperatures are required
  • Cooling tower to recool the cooling water

This gives the opportunity to do dynamic testing from chocolate to caramel and from urea to road bitumen.

  • Max. product feed temperatures of: 280°C
  • Max. product viscosity for pastillation: up to 60000 mPas
  • Max. product viscosity for flaking: up to 100000 mPas

For dynamic testing of Film casting / drying

  • 1 Film casting line with Venturi Dryer modules with winding and unwinding unit. Casting on a steel belt or on a foil is possible.
  • The unit is able to handle water or solvent based casting solutions.
  • Wet or dry film thickness is variable as to the customer need. Normally approx. between 10 and 250µm dry film thickness.
  • Hot air temperatures up to 100 °C are possible in the dryer, even higher temperatures are possible for the belt heating.
  • Casting width between 150mm and  500mm
