Fluid Air® Flour Cooling System

Advantages

  • From 30°C in silo to 14°C in mixer
  • Provides uniform temperature of the dough throughout the year
  • Avoids addition of ice
  • Improves mixing
  • Low operating cost
  • (no CO2)
Application

Flour cooling is required in automated operations to maintain a uniform temperature of the dough and avoid the addition of the ice.
The Fluid Air© system allows to cool the flour dispensed from silos, as well as regulating the temperature by programming a set point.

Design

The flour is mixed with cold air in an intermediate hopper located in between the flour silos and the flour dispensing station.
The cold air is generated by a heat exchanger and continuously circulates in the bin via a high pressure fan and a fluidizing bed.
The air is perfectly homogenized with the flour to give a uniform temperature.
A temperature probe monitors the temperature of the flour and control the heat exchanger till the set point of the temperature.

Throughput from 1 to 2 t/h per unit
Cooling up to 16° from the initial temperature (Δ T 16°C)
The bin is insulated and jacketed to guarantee optimum cooling and prevent condensation.
