Friction Heater

Friction heating is based on molecular rubbing, more precisely the same molecules of the product inside the heater are set in motion and the friction effect releases heat.

 

It is basically composed by an asynchronous motor driven by inverter, the rotor is connected to a special disk, rotating at a small distance from a stator disk.

Applications

Anchor_1

This heater is meant for all kind of liquid without suspended solid particles, of any density or viscosity. The presence of suspended particles is only admitted for those less than 0.2mm and a density percentage at least of 20%, not exceeding.

 

By increasing the temperature, the appearance of such particles may appear different according to their composition: normally they are amalgamated and there is no visible trace at the output of the heater, for this reason the heater can be used, if possible, to perform both the function of the heater and smoothing/homogenizer.

Features

Anchor_2

The friction heater has been designed by Emmepiemme primarily to allow ultra-fast heating without contact with “hot walls”, for products without any electrical conductivity, such as oil, margarine, butter, liquid chocolate, petroleum-based products which could not be heated in ohmic heaters.

It has a global efficiency around 85% and is characterized by a precision, uniformity and temperature stability greater than any other means.

On the other hand, it’s a mechanical object with rotating and mechanical seals, so it presents all the maintenance problems typical of these equipment.

Models

The friction heater is available only for large powers, the smallest model has a thermal output of 50 kW, maximum temperature gap of 50 ° C, maximum outlet temperature of 145 ° C with precision +/- 0.1 ° C and a medium heating time of about 1.5 seconds.
