Newly Developed Equipments and Machines at

Dr. B.S. Konkan Krishi Vidyapeeth Dapoli: A Review

�Konkan is the coastal part of Maharashtra between Western Ghat and Arabian sea.

�This region of Maharashtra is the narrow strip of 40 km width and running 750 km

�Districts: Ratnagiri, Thane, Raigad, Sindhudurg, Palghar and Mumbai

�Sahydari hillocks at one side and Arabian sea at another side

�Annual rainfall 3500 mm which occurs in June-Oct.

• Area under cultivation 9.5 lakh ha

Field crops

• Rice : 4.0 lakh ha

Horticultural crops

• Mango: 1.70 lakh ha

• Cashew: 1.70 lakh ha

• Coconut: 0.3 lakh ha

• Areca nut: 0.03 lakh ha

Major crops in Konkan region

� Small land holding

� Farming on slope,

terraces

� Poor socio-economic

status

� Lack of technical

knowhow

� High fuel cost

� Poor after sales

service network

� Rainfed farming

Hurdles in Agricultural Mechanization in

Konkan region

• The Tractor mounted elevator

is suitable for harvesting of

coconuts and other fruits

• The number of coconuts

harvested depends upon the

actual number of coconuts

available on trees.(400-500

Nos./h).

• Capacity for mango harvesting:

450-500 Nos/h

Tractor drawn Hydraulic Elevator

New Machines developed by DBSKKV Dapoli

• Capacity: 90 to 100

coconut trees/day

• The lifting time and

lowering time of 12 m

height is 40-50 and 30-40

seconds, respectively.

• The capacity of bucket is

200 Kg

• The tractor of 35 HP is

suitable for mounting the

machine.

Tractor drawn Hydraulic Elevator


• The inner drum with pricks and conveying arrangement

• The outer drum is kept stationary

• Inner drum is rotated by the operator using handle

• The pricks fitted on the periphery of internal drum scrarifies the outer shell of the arecanut

Arecanut Scrarifier


• The maximum scrarifying percentage area : 92.44 %.

• The capacity of machine : 1623 nuts per hour.

• The nuts scrarified have better acceptability in terms of colour, texture and test.

• It enhanced the rate of drying of arecanut by 20-40%.

Arecanut Scrarifier


• The major parts are the hopper, lead

screw, cutting blade, handle, lead

screw and cutting plate.

• The teeth on the cutting plate peels

off the husk

• The capacity of the machine: 6 Kg/h

• The breakage percentage : 11.2 %.

• The unhusked arecanut percentage :

3.7 %.

• The efficiency of machine : 85.16 %.

Hand Operated Arecanut Dehusker


• It consist of cylinder, beaters, hopper,

frame and motor.

• The diameter and length of cylinder :

300 mm and 500 mm

• Four beating elements with MS flat

having width and thickness as 40 mm

and 10 mm respectively.

• Rubber pads 40mm width, thickness

15 mm.

• An electric motor (single phase, 1450

rpm, 0.75 hp)

• The concave having the average

aperture:16 mm - 22.5 mm

Motor Operated Arecanut Dehusker


• Average dehusking efficiency and kernel

breakage at 7 m/s peripheral speed and

20kg/h feed rate were 98.1 per cent and

9.9 per cent, respectively.

• The dusking capacity of kernel by

traditional method was 3.6 kg/h.

• Dehusking capacity for power operated

machines were 13 kg/h

• Dehusking cost of arecanut with

traditional method, power operated Rs.

5.1/kg, Rs. 1.9/kg .

• The dehusking cost of power operated

dehusker 62.7 per cent less as compared

to traditional method.

Hand Operated Arecanut Dehusker


• Dehusking efficiency and kernel breakage at 7 m/s peripheral speed and 15 kg/h feed rate: 96.6 per cent and 6.9 per cent, respectively.

• Dehusking capacity :9.8 kg/h,

• Dehusking cost of arecanut with traditional method, pedal operated,: Rs. 5.1/kg, Rs. 3.7/kg, respectively.

• The dehusking cost of pedal operated dehusker, : 27.5 per cent less, over traditional method.

Pedal Operated Arecanut Dehusker


• The dehusking capacity and dehusking efficiency for folding and non-folding type were found to be 58 nuts/h, 93.7%

• Heart rate 3.94 % less and 6.28 % less oxygen consumption rate than non-folding type coconut dehusker.

• The average value of energy expenditure for non-folding type coconut dehusker is more than (11 % more) the folding type coconut dehusker.

• The average value of HR for both coconut dehuskers was less than Limit of Continuous Performance (LCP)

Improved ‘Vaibhav’ Sickle


�The time required17.82 per cent less

over Vaibhav sickle.

�Physiologically, the workload was

found to be ‘moderately heavy’

category for improved Vaibhav sickle

while, that of in ‘heavy’ category in

case of existing Vaibhav sickle.

�Limit of continuous performance:‘less

than limit of continuous performance’

Vaibhav sickle :More than limit of

continuous performance’.

�The field capacity of improved

Vaibhav sickle was found to be 112

m2/h which was 13.1 per cent higher

than existing Vaibhav sickle (99 m2/h).
