The risk of adverse events is ever-present in any spray drying operation. Spray drying is a physical–chemical process in which evaporation transforms liquid into dry powder – and wherever there's powder or dust in spray drying plants there's a risk of explosion or even fire.
Spray-dry powder nozzles are precise and complex devices that can impact a spray plant's profit if they're not operating optimally.
Conventional older-style spray nozzles collect deposits on the exit point of their caps and this product build-up, known as 'bearding', can cause a series of problems for spray drying plants.
Low quality powder and powder consistency problems can be serious concerns for spray drying plants.
Spray nozzle technology in commercial spray dryer plants is complex because the spray nozzles must work at very high pressure levels within explosive powder zones. The quality of the powder is paramount and is subject to hygienic standards requirements.
Traditional spray nozzle technology has a number of problems that reduce production efficiency. These include low quality powder and powder consistency, bearding, sub-standard hygiene, maintenance wear and tear, and safety.
