Scales
Small scales (0-2kg) have been supplied by UNIDO to weigh out small amounts of
ingredients or laboratory chemicals, and larger scales (0-50kg) for weighing root crops. Care
is needed to properly clean scales if they have been used to weigh chemicals before
using them again for food. The small scales can be operated using batteries or mains
power. The large scales should be hung from a door lintel. Calibrated scoops, cups or other
measures, which contain the correct quantity of an ingredient when filled level with the top,
can also be used instead of scales. Operators should be trained to ensure that they use
them properly to measure consistent weights. The scales have no spare parts or routine
maintenance. They should be cleaned after use using a damp cloth.
Sulphuring cabinet
A cabinet can be made from wood, covered in either plywood or polythene and fitted with
mesh trays to hold the sliced crop. The cabinet can be either lifted off the stack of trays for
loading/unloading or it can be fitted with a sealable door. The aim is to retain sulphur dioxide
gas from burning sulphur inside the cabinet so that it can penetrate the slices. There are no
spare parts or routine maintenance. Trays are cleaned after use with a brush and detergent,
rinsed with clean water, and properly dried in the sun before re-use.
