| Summary: |
Soybeans are nutritious foods that contain lots of protein. Foods made from soy beans that are often
found is tempeh. The process production tempeh in Indonesia, both in industries or traditional scale are basically
similar. The difference lies in the way of peeling the cuticle soybean seeds. Peeling skin soybeans traditionally
have weaknesses, among others, in terms of time this process takes a long time, and in terms of cleanliness and
health of the process is very unhygienic. It is necessary to develop technologies and equipment to peeling the
husk, clean and hygienic. The purpose of this study is to determine the optimum rotation soybeans the cuticle
peeler and economic analysis.
The design of manufacturing soybean the cuticle peeler using a variable rotation speed (rpm) based on
the diameter of pulley: 10, 8, 7, 6, and 5-inch, clearance space: 2.0; 2.25, and 2.5 mm. The result is a soybean
seed husk is peeled and cut into 2 (two). Manufacturing peeler cuticle of soybean type of screw and the high of
pegs for soybean industry began with the design of forms, image design, selection of materials and processed
with standard production equipment and test its performance. Optimization testing soybean peeler the cuticle by
the rotation speed between the end of the peeler cylinder (cylindrical mill) with the body cylinder mill with a
production capacity and testing variations size of pulley.
Based on the test results it can be concluded that the optimal results peeler cuticle of soybean type of
screw, the rotational speed in 386 rpm and 10 inches in diameter pulley and also in 2.5 mm of clearance space
