GUIDE:- Mr.NOUSHAD (Asst.professor mech)

INTRODUCTION GENERALLY, COCONUTS ARE DEHUSKED MANUALLY

USING EITHER A MACHETE OR A SPIKE [1]

ATTEMPTS AT MECHANISATION HAS SO FAR EITHER BEEN

NOT FULLY SUCCESSFUL OR ENDED UP TOO COSTLY

DISADVANTAGES OF PRESENT TECHNIQUES:

TIME CONSUMING

HUMAN EFFORT REQUIRED

LACK OF MAN POWER AVAILABILITY

COCONUT DEHUSKING MACHINE USES ELECTRIC

POWERED ROTARY BLADE MECHANISM TO TEAR OFF THE

HUSK FROM COCONUT

AIM OF PROJECT

WITH COCONUT DEHUSKING MACHINE WE AIM TO

PROVIDE :

LOW COST COCONUT DEHUSKING

REDUCTION OF HUMAN EFFORT

REDUCTION OF MANPOWER REQUIREMENT

IMPROVEMENT ON NUMBER OF NUTS PROCESSED PER

HOUR

WORKING PRINCIPLE

WORK ON PROGRESS

1. G I pipe

4inch diameter 2 pieces 40cm each

2. MS rod 4 pieces 10cm(2 pieces) 20cm(2 pieces) 30mm diameter

3. M S flat plates 5mm thick 3cm length 3cm width

4. plummer block with bearings 4 pieces 30mm inside diameter

5. gears2 pieces30mm inside diameter

ASSEMBLY

ADVANTAGES

FAST OPERATION

LESS MANPOWER REQUIREMENT

LABOUR REQUIREMENT MINIMUM

CAN BE CLUBBED ALONG WITH HUSK SHREDDING UNITS FOR

MASS PRODUCTION

NUTS PER HOUR HIGH COMPARED TO PNEUMATIC AND

HYDRAULIC SYSTEMS

COST LESS COMPARED TO PNEUMATIC AND HYDRAULIC SYSTEMS

CONCLUSIONTHROUGH THIS PROJECT WE WILL BE ABLE TO OFFER

LOW COST DEHUSKING SOLUTION

MAXIMUM SCRAP UTILISATION

120 TO 200 NUTS PER HOUR

ON APPLYING MODIFICATION WE CAN

MAXIMIZE DEHUSKING EFFICIENCY

REDUCE SPEED OF ROTATION

IMPROVE TORQUE
