Industrial Coffee GrinderSTROTOR

Requires separate cooling process
Coffee Grinder Strotor grinds the raw material without contact with two rolls and does not produce heat from friction; there is no worry of altering the product or the raw material despite usage over long duration.

Product features

  • Two rolls to grind the raw material without contact

    The existing millstone-type grinding grinds the raw material through friction, which easily heats the roll to a high temperature. While there is no problem grinding small amount, grinding a long duration with heightened grinding capability can easily bring the equipment to a high degree that can burn the product, requiring separate cooling process. Coffee Grinder Strotor grinds the raw material without contact with two rolls and does not produce heat from friction; there is no worry of altering the product or the raw material despite usage over long duration.

  • Ensures longevity

    Ensures longevity. Coffee Grinder Strotor has specialized surface process; it has strong wear-resistance and the roll is unharmed even if foreign substance such as a metal piece is stuck, ensuring a long usage. (In case of coffee, it can be used for 20 years)

  • No static.

    It uses grinding which splits the beans, rather than friction grinding, and thus static from existing millstone-type grinding does not occur.

  • Easy particle control

    4 to 8 rolls, precisely manufactured, are composed in 2 to 4 levels, two levels in a group, and precisely grinds by level, making it easy to control desired particle size.

Application of V-Cutting method

  • V-Cutting method: Grinding method which puts the raw material between the two rugged parts of the cutting roll like a bridge, then pressing the center
  • Coffee Grinder Strotor uses the principles of V-Cutting method, using the rugged parts on the surface of 3 rolls to grind the inserted raw material in radial shape (V-Cutting)
  • The grinding roll of Coffee Grinder Strotor is a cutting-type grinding roll with narrowed roll pitch and roll clearance, capable of grinding to the desired particle size through grinding in stages.

Features of V-Cutting technology

  • The shearing force does not affect the raw material and can set the retention of the granulation high, producing small amount of fine dusts.
  • No contact between the cutting rolls, as well as instantaneous contact between the cutting roll and the raw material prevents sparks.
  • V-Cutting method is not a grinding through friction or impact; thus, heating or abrasion does not occur on the roll surface despite continuous grinding over a long duration
  • Fine dusts do not clot on the surface of the granule through V-Cutting method, making grindings of 100 mesh or 150 mesh easy.
