Design Specifications

Design specifications:

  • Galvanized steel body in bolt together panels (packed flat for transport).
  • Cast iron spiked rustlers are fitted in rows to the base of the rotor which is moved backwards and forwards manually.
  • This action breaks the shells against the wire screen that forms the curved base to the machine.
  • The shell pieces can then be winnowed away from the kernels.
  • Two sizes of wire screen (9mm and 11mm) are supplied with each unit to suit differing varieties.
  • Volume (m3): 0.05
  • Weight (kg): 30

Manufacturer Specified Performance Parameters

Performance targets: Interview with representative

  • Shell up to 100 kg/hr
  • Best results on the GS100 models are achieved if the ‘in shell’ nuts are graded into small, medium and large sizes.
  • The machine is then set to suit one of these grades and reset for the next grade later.
  • In this way breakage into large kernels of unshelled nuts is minimized.
  • The concave screen is easily interchangeable so that different perforation sizes can be used for different grades.
