Potato plate manufacturing process

Transcript

Weigh ingredients

Potato starch, cellulose and carnuba wax are weighed and mixed with water.

Input ingredients

The potato starch mixture goes into the hopper, where an auger carries the mixture and keeps it moving to prevent clumps forming.

Place in mould

A precise amount of the potato starch mixture is dispensed into swivel containers, which tip the mixture onto a mould heated to 250°C.

Compression moulding

A metal plate presses the potato starch mixture into the mould. The mixture expands, like popcorn, and forms a foam-like material. Steam and excess potato starch mixture are forced out through vents in the mould.

Remove from mould

Robotic arms remove the plates from the moulds and deposit them on the side.

Quality check

The plate is checked for quality, any extrusions are removed and rough edges are sanded.

Curing

Plates are stacked and left overnight in a curing tent to prevent warping.

Packaging

Plates are counted, shrink-wrapped, labelled and put in boxes for delivery in New Zealand and overseas.
