Working principle
Tetra Pak® Spray Dryer Wide Body is fed from the evaporator. From the feed tank product is preheated with concentrate heaters and pumped with a high pressure (HP) pump to the HP nozzles. Drying air is pre-filtered and heated by means of heater, using steam, natural gas, electricity or oil as energy source.
In the Sunflower air distributor drying air is guided in a controlled and well definedway via a venturie into the centre of the drying chamber. Product is sprayed in the airflow as fine droplets. If agglomeration is required, fines are fed into the flow as well.
In order to guarantee the optimal position of the nozzles, the lances are positioned on a swivel, wherewith we can adjust the nozzle orientation. If a non-agglomerated product is run, the fines returns to the shaking bed instead of the top of the dryer, and lances can be positioned in amore outward position.
The airflow inside the drying chamber follows a co-current reverse flow, which means air travels down with the product and in the cone product travels towards the cone outlet, whereas air leaves the drying at the top.
