Abstract

In the metal drilling process, tool temperature is an important parameter for optimizing cutting conditions, by limiting tool wear so that surface roughness can increase. The temperature rise that occurs in the metal drilling process is related to the rate, drill speed, and drill diameter, the drill speed which has a significant influence. One of the efforts to reduce the temperature of the drilling process is by using the Minimum Quantitative Lubricant (MQL) method. The MQL method is more effective by utilizing the surrounding air by making a fan that produces cold air. The method of this research is Computational Fluids Dynamic (CFD) simulation using flow simulation, with parameters 3 shapes of the blades, and variations in the number of blades 3,5 and 7. The purpose of this study is to analyze the shape and number of blades on a portable chip fan for metal drilling cooling processes. The CFD simulation results obtained from Model 2 and the number of blades 3 with a minimum temperature of 29.87°C and a maximum temperature of 30.19°C.

Abstract

Huller is the main machine that determines the quality and quantity of production in the rice milling industry. The current problem, especially in the small-scale rice milling industry, is that they still use locally made huller machines that use 6-inch diameter rice rubber rollers with a capacity of 800-1,200 kg/hour. Local huller machines produce a yield (broken rice) of 30-40%, so three huller machines and one polisher machine are needed in one production line. This machine assembly requires energy, human power and high costs. With these problems, a machine is needed that is capable of increasing the yield and milling capacity. Huller machine with horizontal rice rubber roller has a dimension specification of 1.3X0.9X2 meters; Rice rubber roller diameter 10 inches; 3 phase electric motor 20HP 15KW 1,500 rpm. The huller machine has been tested at the CV. Putra Maju rice mill, Wirakanan Village, Kandanghaur District, Indramayu Regency for 4 months. Test results Huller machine capacity 1,600 kg/hour ± 50 kg with a yield of 72% ± 2%.
