TIMELINE OF THE PROJECT 2COFFEE PULPING MACHINE ABSTRACT To pulp
the coffee with existing technology combined with implementing new
innovative modifications by fabrication and design
To improve the capacity of the pulper by unique design of
shoe
To increase the speed of the pulper manually using pedal
mechanism
3COFFEE PULPING MACHINEINTRODUCTIONTraditional single disc
coffee pulpers with hand operated are common in designThey have a
speed of around 60 RPM and the Shoe is having one humpThe Outer
body is made of cast iron and the operation is a tiresome
businessProviding mild steel body is economicalProviding peddle
mechanism increases the speed to around 80 RPMProviding double hump
in the shoe makes pulping cleaner
COFFEE PULPING MACHINE4LITERATURE SURVEY
Coffee pulper is fed with measuring unit called
Bushal.1bushal=43 kgs of raw coffee.On pulping an average of 17kgs
of pulped seeds are obtained incurring 60Rs cost.50kg/bag * 10bags
= 500Kg/acre1bushal plucking- 130Rs/labourA labour plucks 3
bushal/dayAverage costs for one acre:1000Rs for plucking180Rs for
cleaning500Rs for laboursHence total cost= 1680Rs/acre

MACHINEPROBLEM IDENTIFICATIONThe current manually operated single
disc pulping machine is having small capacity
The pulping action takes place at lesser speeds in hand operated
pulping machines
Also rotating the machine with hand is a tiresome work 7COFFEE
PULPING MACHINE7PROGRESS OF THE PROJECTWe are working on the
project from past one month and have conducted literature survey on
the problems the coffee planters are facing by visiting some
plantations.We are doing our project in an engineering works and
right now assembling the various parts is taking place.

CONCLUSIONUltimately the objective of the project is to reduce
the cost of the machine as well as to make ease of operation of the
machine with simple existing technologyWe hereby want to say that
our project will complete with in one week and we are sure that it
will operate in a successful way11COFFEE PULPING
