Abstract

Research, Study and Experiment for Water Absorption in Coconut Curries Objective To study the penetration force of two piercing needles: Tipped punching needle And the needle tip pierced through the three drilling positions, namely the top, side, and bottom of the coconut to bring the lowest and highest measured force values ​​of both types of piercing needles to design and build. Automatic coconut curry ball punching machine to suck and separate the coconut water for the next occasion. Operation steps The physical characteristics of the coconut curry were studied. After that, a study of the design and construction of both types of punching needles was studied. The cutting edge is beveled at 30 degrees and the point is sharp. The point angle is 50 degrees. The device was then tested for the drilling force of the coconut curry balls in all 3 positions, top, side, and bottom using a pressure testing machine, then comparing the minimum and maximum penetration force of all puncture needles. There are two characteristics in each position. Performance, By comparison, the drilling force applied to the top, side, and bottom. Found that the needle pierced the end of cutting The drilling force was applied 0.777, 0.958, and 1.493 kN, respectively. The drilling force was 1.34, 1.466, and 1.75 kN, respectively. It was found that the penetration force of the punching needle, the cutting end characteristics. At the top, elephant, and bottom positions to pierce the curry balls The mean value was significantly lower than that of the pointed needle.
