 Food Grading/Sizing Machine
 Food Grading or Sizing Machine. 6 separate compartments for sorting plus oversize.
 We have one of these available.

Designed and Built by E.B. McDonald Engineering

Was originally used by a large scale food manufacturer.

This conveyor utilises tapered band conveyors which convey the product, the gaps between increase to allow product to fall through by size.

There are 6 x compartments for the material to be graded into plus an oversize chute at the end.

The unit has stainless steel feed hopper with an adjustable opening to regulate the feed rate of the product/s to be graded.

Provision for a bin to be slid in under each outlet chute, but could be used in conjunction with conveyors mounted below the sizing outlets to convey away graded product if a more automated process was required

Grading size starts out at approx 5mm, up to approx 16mm. Anything bigger carries on out the end to the oversize chute.

By taking out every 2nd band, the sizing would range from approx. 18mm to 40mm.

The rubber bands are approx. 10mm diameter.

Powered by a 0.37Kw three phase geared motor. This has an output speed of 59 RPM.

This then drives a drive chain with 19 teeth and 57 tooth sprockets giving a further 3:1 reduction.

The drive drum is approx 300mm diameter.

This gives an approx. belt speed of 18.5 metres per minute.

On swivel caster wheels for easy maneuverability.
