Mechanisation in sericulture
ByA.Suresh.
Why mechanisation?
The sericulture industry in india is highly labour intensive. In india over 65-70 % cost of cocoon production accounts for labour wages for different activities.
Hence ,we should reduce labour dependency to reduce cost of cocoon.
MECHANISATION IN MULBERRY
CULTIVATION
Land preparation:Tractor operatedMouldboardDisk ploughCultivatorsHarrows
Prepared the land fast
and less cast.
Mulberry cutting:
Worker -1500-2000 cuttings/day.Machine-1400-1500
cuttings/hour.Developed by CSRTI,Mysore.
Intercultural operations:

Shoot Harvesting: Knapsack type bush cutters for mulberry
shoot harvesting. It works well in paired row plantation
and can harvest 1,000-1,200 kg shoots per hour.
Mostly used in medium and large farms.
MECHANISATION IN
SILKWORM REARING
Rearing house disinfection:Electricity and engine operated
sprayer.Flame gun developed by
CSRTI,Mysore.Highly cost and time effective tool
Leaf chopping:
CSRTI leaf chopper-225-250 kg leaves/hour Different sizes for different age silkworms. Most useful for Chawki rearing centres-
large scale young age rearing.
Silkworm separator:Separate 100
dfls(40,000-45,000 silkworms)/hour
Avoid spinning of cocoons in bed
Reduce the cost of manual picking
Deflossing of the cocoon:
The outer layer of unreelable silk floss removed before reeling.
Deflossing the cocoons at very fast rate &save labour charges.
Marketing price will increase. Deflossers, CSRTI,Mysore.
Hand operated deflossers-small rearer
Motorised deflossers-medium &large rearer
Tray washing machine:
Large no of plastic trays are to be washed in a Chawki Rearing Centre.
Capasity-60-70 trays/hr.
Collapsible mountage pressing tool:
Quick & proper folding & pressing of the plastic collapsible mountages.
Developed by CSRTI,Mysore.
Fast bundling of the plastic moundages.
