M^cKINNON Coffee Precleaners are designed to clean and screen coffee, prior to feeding on to the next processing stage.The machine effectively removes iron particles, stones, sand, rubble, leaves, twigs and other unwanted matter.
   Separation is achieved by a series of screens, the first screen removing large impurities and the bottom screen removing fine materials such as sand and dust. The middle screen separates the coffee and delivers it clean. To increase the efficiency of cleaning, an Air Sifter is used after the precleaning.

  The machine requires minimum maintenance and has individual rubber ball cleaning mechanisms to ensure that the screens have maximum screening area at all times. The screen inclination, throw angle and amplitude can be varied, depending on the input product for ideal results. Vibratory motion of the screen is effected by means of two low power vibratory motors.

   The machine can be provided with a Closed Aspiration System or can be connected to a Central Aspiration Line.
