Counterflow cooling system cooling pellets after pelletizing
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.
The Van Aarsen counterflow cooling system is designed for cooling pellets after pelletizing back to ± 5°C above ambient air temperature.
This is to achieve a good PDI, flow ability, protect against decay and minimize chemical and biochemical reactions.
Benefits
Small foot print
Low energy consumption because of low air volume.
Minimum service down time.
Continuous pellet discharge for optimal cooling process.
Limited damaging of the product due to discharge mechanism.
Complete emptying of the cooler, to minimize cross contamination and maximize hygienic operation.
Optimal pellet moisture content.
Optimal process control.
Available and upgradable as double deck cooler, for quick product change-over.
Robust design of discharge mechanism.
Features
Inlet valve for continuous product flow and air lock.
Ultrasonic continuous layer thickness measurement to ensure and/or control retention time in cooler.
Automatic air flow control by motor-operated air valve to regulate air speed in cooler.
Cooler bin walls and hood in stainless steel to avoid corrosion.
Hydraulically operated discharge mechanism.
Frequency controller for adjusting speed discharge mechanism.
Octagonal construction for optimal filling of the cooler.
Bin height configured for optimal (build in) height.
Designed and constructed according to CE and ATEX safety regulations.
