Simple coffee pulper
A coffee berry pulper has been developed by Sudhakar to extract the coffee seed
separately without much damage to the fruit. This is a simple hand operated device,
which is compact in size. It can be easily dismantled into small units, transported and
assembled wherever it is needed for the purpose. In a round disc there are slots to fit the
size of the coffee berry. The fruits are fed into the device through a side pipe. Operating
the handles on either side rotates the wheels, which help in separating the pulp without
damaging the coffee bean. The pulp will come out through another pipe and get collected.
The capacity is up to 30 kilos in each operation, depending upon the diameter of the
disc. For instance, a disc of one foot of diameter will operate up to 15 kilos of coffee
beans at a cost of Rs 5,000 per unit, whereas a bigger disk of 1.25 feet diameter, whose
capacity is for 20 kilos, will cost around Rs 6,500.
