High shear mixer seal leaks: causes and checks
A leaking shaft seal on a high shear mixer is one of the most common maintenance calls.
Spray dryingSpray dryer powder build-up: causes and checks

EvaporationEvaporator fouling and falling capacity: causes and checks
When an evaporator gives lower concentrate solids or needs more steam as the run goes on, fouling on the heating surface is the usual cause.
High shear mixingLumps and undissolved powder after mixing: causes and checks
Lumps, often called fish-eyes, form when powder is wetted on the outside before it is dispersed.
Liquid processingPlate heat exchanger leaks and mixing of media: what to check
A plate heat exchanger can leak to the outside, or leak inside so that product and service media mix.
