This document provides information about a student mini project to design a low-cost coconut dehusking machine. It introduces the group members and their guide. It notes that coconuts are currently dehusked manually using tools like machetes, which is time-consuming and labor-intensive. The project aims to create an electric powered rotary blade machine to remove the husk more efficiently. The document outlines the machine components, working principle, work in progress including materials being used, and advantages of the design such as reducing labor requirements and increasing processing capacity. It concludes the machine could offer a low-cost dehusking solution processing 120-200 nuts per hour.

4. 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

5. 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

6. MACHINE COMPONENTS
FRAME
BEARINGS & BEARING HOUSING
GEARS
SHAFTS
BLADES
ELECTRIC MOTOR

13. ASSEMBLY

14. 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

15. CONCLUSION
THROUGH 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
