Coolers

Icon Cooling

The Van Aarsen counterflow cooling system is designed for cooling pellets after pelletizing back to ± 5°C above ambient air temperature. This is done to achieve a good PDI, flow ability, protect against decay and minimize chemical and biochemical reactions.

Kalmar Lantman Cooler
1

Octagonal construction for optimal filling of the cooler

2

Continuous pellet discharge for optimal cooling process

3

Complete emptying of the cooler, to minimize cross contamination and maximize hygienic operation

4

Limited damaging of the product due to discharge mechanism

5

Ultrasonic continuous layer thickness measurement to ensure and/or control retention time in cooler

6

Automatic air flow control by motor-operated air valve to regulate air speed in cooler (positioned after filter cyclone, before fan)

7

Cooler bin walls and hood in stainless steel to avoid corrosion

Counterflow coolers

The counterflow cooling principle was invented by Van Aarsen and has become a standard blue print, copied all over the world within the compound feed industry.
