Bottle/jar washers
The time consuming part of washing jars
is rinsing out the detergent and washers
are used to reduce this time. They are
made by soldering vertical pipes onto a
larger base pipe and connecting the base
pipe to a water supply. In use the jars are
inverted over the vertical pipes and rinsed
until free of detergent. No spare parts are
required, and there are no maintenance or
cleaning requirement,.

Chippers/Slicers
Manual slicing machines can be used to produce slices of uniform thickness for snackfoods
or dried root crops. A range of manual, pedal or powered chippers is available for root
crops. Most operate by holding the root against rotating blades, but machines that force the
root past stationary blades or ‘guillotine’ type cutters are also available. The blades should
be periodically sharpened and the equipment should be washed with detergent and clean
water after use.

Cyclone separators
A fan sucks flour from the mill and transports it to a
cyclone separator. In the cyclone, flour rotates inside
in a spiral action and is separated from the air,
causing it to drop into a collection bag underneath.
The air escapes via a vent pipe at the top of the
cyclone, preferably to the outside of the building.
Fig. 5.7 Cyclone separator
It is important to design the cyclone separator
correctly to avoid losing product into the air. The inlet
pipe must enter the cyclone tangentially, and the
outlet (vent) pipe should be three times the area of
the inlet pipe.
