Analytical Study on the Production Capacity of Soybean Grinding Machine for Producing Tofu

Abstract

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 performance of machine is evaluated by 30 evaluators and obtained the 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.
