Multiplier onion (Onion aggrega tum) is consumed in large quantity
in southern provinces of India.
These are used in large quantities in
the catering and pickling industries,
creating a need for peeling equip ment. Multiplier onion peeling is an
essential step in producing many
of the onion products such as dehy drated onions, onion powder, onion
flavoring, onion salt, onion rings,
and pickled and canned onions,
which is a very tedious process. A
batch type peeling machine suit able for farm-level operation was
designed and tested for multiplier
onion. The equipment consisted of
a cast aluminum drum seated over
a rotating disc. Inner surface of the
drum and top surface of the lower
disc are covered with corrugated
rubber sheet which aids in the peel ing process. The multiplier onion
needs to have the ends cut with a
sharp knife and soaked in clean
water for a period of 10 min to as sist the loosening of peel followed
by air drying for 1-2 min to remove
the surface water. Major operational
parameters: speed of operation and
abrasive surface on the drum were
optimized for peeling efficiency,
damage to the bulb and other performance parameters. The capacity
of the peeler was about 50-60 kg/h.
The peeling efficiency was about 92
percent with unpeeled and damaged
percentage being 6 and 2 percent,
respectively. The cost economics
study revealed that the equipment
had a saving in labour and cost to
a tune of about 68 and 69 percent,
respectively, with a payback period
of 1.40 years. The equipment can be
adopted by small and medium multiplier onion processing industries.
