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

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.
