Precision spray nozzles (food processing)
Precision spraying of small metered amounts of fluid is a common application within the food industry. The XA series of air atomising nozzles allow for exactly this. As a twin fluid nozzle, the breaking up of the spray into a fine pattern is achieved by smashing compressed air (or other gas) into the primary fluid. The use of air in this way gives a number of advantages for food processing applications.
1- Very low flow rates of fluid at low pressures can be finely atomised. If the pressure of the fluid itself was used to break up the flow (as in other types of nozzle) this would not be possible.
2- The XA series of nozzles can be fitted with an automatic cut-off pin that is powered by the compressed air system. This allows for precise “stop/start” spraying, for example on a moving conveyor of product.
3- The level of atomisation can be varied independent of fluid pressure.
The XA series comes in a number of configurations. Full details on the whole product family can be found by clicking on the box below.
For further control still the SAM series of air atomising nozzles could be considered. These nozzles have a secondary air feed that is used to control the shape of spray. This means that both levels of atomisation and spray pattern can be varied by changing air pressure independent of each other and of the fluid pressure.
