| Summary: | The aim of this research was to optimize the liquid removal from Mesona chinensis Bentham using a centrifuge machine. The centrifugal machine was properly designed in order to improve the liquid removal from Mesona chinensis Bentham. The power transmission shaft was designed and calculated based on the ASME standard. Stress of the power transmission shaft was simulated using the SolidWorks software program. The machine was built and tested.
The shaft speed, time consumption and screen size were studied. The Box-Behnken design response surface method was used to determine the optimum operation of the centrifugal machine. The results showed that the power transmission shaft used for the machine was 25 mm. A quadratic polynomial equation was fitted. The optimal conditions of separation obtained from the model were found at the shaft speed of 810 rpm, time consumption of 90 s and screen size of 100-mesh which yielded 555.33 g of liquid separated from 1,000 g of initial Mesona chinensis Bentham solid.
