Abstract

The modified coffee pulper is made of wood, galvanized iron sheet and steel plates. The average output is 50.7 kg/hr, about 1.5 times the output of the original machine. The storage duration of the berries after harvesting significantly affected the pulping capacity of the machine. The pulping capacity was highest (51.1 kg/hr) when the berries were stored 5 days prior to pulping and was lowest (49.9 kg/hr) at one day storage duration.
