Coffee Peeling Machine Design

Abstract

Coffee is a commodity crop that has an important role in economic activities in Indonesia. Coffee is also one of Indonesia’s export commodities are quite important as a producer of foreign exchange in addition to oil and gas. In addition to the export opportunities increasingly open, the coffee market in the country is still enough of a major of this research is to produce a coffee peeling machine design and to know how to work the coffee peeling machine. Coffee peeling machines is expected to help farmers in the harvest with a maximum peeling and effective in use. With the existence of this machine can work in accordance hopes accordance with the wishes of farmers, as well as to increase the selling price is higher. In this study are analysing the problem, conceptualizing the design, manufacture schematic function block diagram, load calculation, material selection, until finally get a working drawing. The design method described with the design method used in the coffee peeling machines or machine depulper and the method is called the method of French design. Skin peeler machine coffee made with a capacity of 370 kg / h, using the prime mover’s gasoline engine with a power of 5.5 Hp and rotation can be changed as desired change from 1400 up to 4500 rpm. Round to be changed by prime movers’ belt - puly with a ratio of 1: 5. While the engine has the dimensions of length, width and Height of each is 727 x 457 x 1110 mm with a weight of 103 kg.
