Spray dryer, tank & silo crack testing helps to eliminate any sources of microbial contamination which may lead to product spoilage or transmission of diseases.

Accutest International leads the field in this activity and has a wealth of experience in the food, dairy, brewing and pharmaceutical industries.

Our 100% reliable method and specialist use of fluorescent, food safe & nontoxic biodegradable liquid penetrant is the most reliable for this important internal inspection and we ensure that production downtime is minimal, whilst ensuring our clients’ audit requirements are met. Our spray dryer, tank & silo crack testing & inspection service is also the perfect solution for routine examination of cyclones, fluid beds & bag filters.

Furthermore, our state of the art inspection platform has many advantages over traditional scaffolding methods:

  • No risk of splinters or debris from wooden planks
  • No blind spots below scaffold pole supports which have not been tested
  • Less downtime
  • Significant cost savings
