The performance evaluation of a folding type and non-folding type manually operated coconut dehuskers was carried out at College of Agricultural Engineering and Technology, Dapoli for its suitability to farmers on the basis of dehusking capacity, dehusking efficiency, damage percentage and overall discomfort rating(ODR) and body part discomfort score (BPDS) during operation. Dehusking of coconut is very drudgerious operation.To reduce drudgery in the operation Dr. BSKKV, Dapoli develop two types of coconut dehusker one is folding type and another is nonfolding type manually operated dehusker. The performance of folding and non-folding type manually operated coconut dehusker was evaluated. The dehusking capacity and dehusking efficiency for folding and non type coconut dehusker were observed as 58 nuts/h and 93.7 % and 52 nuts/h and 93 % respectively. No damage to coconut shell dehusked was observed with both type.The mean value of overall discomfort rating of subjects for coconut dehusking operation with folding and non-folding type dehuskers was 3(light discomfort ) and 4 (more than light discomfort) respectively. The average BPDS score while performing the coconut dehusking operation using folding type and non-folding type manually operated coconut dehusker was 5.8 and 6.1 respectively.
