GENERAL INFORMATION
• Scraper blade are extremely hard and therefore subject to nicks when
mishandled.
• Blades are designed to give maximum service. Wear depends on operating
conditions.
• Products with a high percentage of water and products that contain certain
fruits or grit accelerate wear.
• Running dasher too long during the cleaning operation or running dasher
dry is not raccomended.
• Avoid bending blades when removing the dasher from the inner cylinder.
Follow the instruction for dasher removal. Bent blades should not be used.
They will not scrape the cylinder wall properly, greatly lowering the
efficiency of heat exchange.
• Scraper blades need reconditioning when the scraping edge becomes
"knife-sharp", rounded, or nicked. Remove the blades for reconditioning
monthly, and replace with a reconditioned set of blades.
• The length of time which blades remain in good condition will depend
largely on the type of product being processed. Experience will determine
frequency of reconditioning.
BLADE RECONDITIONING
• Blades that have a heel over 0.75 mm (1/32 inch) should be reconditioned.
After the blade has been repeatedly filed or reconditioned down to 31.7 mm
(1-1/4") width (see fig. 3), it should be replaced with a new blade. To permit
sufficent time for good reconditioning, a spare set of blades should always
be kept available.
