Sorter/Classifier – capacity up to 200kg/hr

After cracking, the classifier can be used to separate fractions into different sizes for maximum efficiency in winnowing. The top deck acts as a scalper, removing un-cracked (possibly slaty) beans.

  • Five decks, with mesh sizes 3/8", 1/4", 1/8", and 1/16" (top deck is for scalping)
  • ~25kg hopper with automatic feeder
  • All stainless steel construction

Impact Cracker – capacity up to 200kg/hr

  • Compact footprint
  • High throughput with minimal losses
  • Cracking mechanism works on beans of any size
  • Cracking mechanism is virtually un-jammable, so you never have to worry about poking and prodding beans through
  • Digitally adjustable speed control for adjusting cracking power to optimize cracking of beans with varied shell thickness and moisture content
  • Works on unroasted as well as roasted beans
  • Cracking creates considerably less dust/fines than roller mill type crackers which equates to higher yield in winnowing, more final product, which directly equates to more revenue
  • Cracking produces larger, more uniform, and fewer pieces of shell, so winnowing can be completed more quickly.
  • Zinc treated, powder coated frame to resist rust in wash down environments, even in the event of chipping
