1. Mechanisation in
sericulture By
A.Suresh.

2. Why mechanisation?
The sericulture industry in india is highly labour intensive. In india over % cost of cocoon production accounts for labour wages for different activities.
Hence ,we should reduce labour dependency to reduce cost of cocoon.

3. MECHANISATION IN MULBERRY CULTIVATION

4. Land preparation: Tractor operated Mouldboard Disk plough Cultivators
Harrows
Prepared the land fast
and less cast.

5. Mulberry cutting: Worker -1500-2000 cuttings/day.
Machine cuttings/hour.
Developed by CSRTI,Mysore.

6. Intercultural operations:
Power tiller
Power weeder
Tractor operated cultivators

10. 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.

11. MECHANISATION IN SILKWORM REARING

12. Rearing house disinfection:
Electricity and engine operated sprayer.
Flame gun developed by CSRTI,Mysore.
Highly cost and time effective tool

13. 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.

14. Silkworm separator: Separate 100 dfls(40,000-45,000 silkworms)/hour
Avoid spinning of cocoons in bed
Reduce the cost of manual picking

15. 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

16. Tray washing machine:
Large no of plastic trays are to be washed in a Chawki Rearing Centre.
Capasity trays/hr.

17. Collapsible mountage pressing tool:
Quick & proper folding & pressing of the plastic collapsible mountages.
Developed by CSRTI,Mysore.
Fast bundling of the plastic moundages.
