This process enables the seamless transformation of liquid products into the coveted pastille form – and in a way that not only optimises our production processes, but also guarantees consistently high product quality.

What is pastillation?

Pastillation is a process that is particularly suitable for converting molten products into pastilles. The highlight here is that this process takes place on a specially developed cooling belt system that has proven to be extremely efficient and versatile.

The process of pastillation

As the cooling belt is sprayed with cooling water from below, the droplets cool down until they are completely solidified. This is where the pastillage unit comes in. It divides the incoming liquid product into individual drops, which are then deposited on a stainless steel cooling belt. The cooling belt is sprayed with cooling water from below. This cools the drops until they are completely solidified. As a result, the pastilles obtained are not only almost identical in size, but are also round and dust-free.

Wide range of applications

The pastillation systems offer a wide range of possibilities. Products in the viscosity range of 0 – 30,000 mPas (cP) can be pastillised without any problems, whereby the sizes of the pastilles can vary from 1 to 25 mm. The performance of these systems is impressive, ranging from 400 to 800 kg per hour. The actual output depends on factors such as the initial temperature of the liquid and when the solidification point is reached.
