Taho and tofu are common snacks that are available nationwide, and also a good source of
protein. The machine used for grinding varies based on the nature of the producer. Small
local enterprises utilize a custom-made grinding machine that is made up of two grinding
stones enclosed in a cast iron that is connected to a shaft which is connected to a motor
through a belt drive. The main objective of this study is to develop a machine that could
increase the production of small factories from twenty (20) kilograms to 30-50 kilograms
of grinded soybeans by increasing the speed of the motor without generating much heat in
the process that could affect the quality of the soymilk produced. This was achieved by
using the principle of a hammermill instead of grinding stones, in which the extraction
process undergoes pulverization instead of compression. Test results had shown that the
machine could grind 5-10 kilograms of soaked soybean in less than 10 minutes. The use of
motor control increases the functionality and user-friendliness of the machine. The
prototype is presented to thirty (30) evaluators to determine its performance the project
obtained a mean score of 4.53 which means Excellent. This concludes that the soybean
grinding machine had managed to achieve on increasing the production and the use of food
grade stainless steel that have a high corrosion resistance which prevents contamination
and also improves the quality of the machine.
