Spray drying is the most widely used industrial process involving particle formation and drying. It is used for the continuous production of dry solids in either powder, granulate or agglomerate form from liquid feed stocks (ie cows).
The spray drying process involves the atomisation of a liquid into a spray of droplets and contacting the droplets with hot air in a drying chamber. Evaporation of moisture from the droplets and formation of dry particles proceed under controlled temperature and airflow conditions. Powder is discharged continuously from the drying chamber.
GMP (Good Manufacturing Practice), HACCP programmes and pathogen monitoring are essential for effective food safety programmes. Routine integrity inspection of the drying chamber that complies with the latest guidelines, directives and legislation is required.
Independent Integrity Inspection Limited (INDEi) offer a comprehensive inspection service for the periodic examination of spray dryers. Using our purpose built and designed access platform INDEi personnel carry out a critical examination of the internal surfaces of driers up to ten metre diameter without the need to erect expensive temporary scaffolding. Our personnel working strictly within the “Working at Height” legislation are able to complete a detailed and thorough examination using eddy current, penetrant and visual inspection methods of all seam welds, plate surfaces and suspect areas such as hammer marks.
Our access platform and working practises reduce the examination time to less than three days, although emergency inspection and repairs can be carried out in a single day.
The access platform has many advantages over traditional scaffolding methods, such as:
• No risk of damage to the internal surfaces of the spray dryer from scaffold poles.
• No risk of wood contamination.
• No blind spots below or adjacent pole supports
INDEi personnel are trained and qualified to in accordance with PCN, SNT and CSWIP overseen by The British Institute of Non Destructive Testing and The Welding Institute, assuring our clients have total confidence in a professional service.
