ANAIN, ANDRE MARIE G., MABASA, DARWIN G., AND TIBAYAN. MYRNA TERESA L. Design and Testing of a Microcontroller bases Sweetened Yam Mixer. Undergraduate Design Proiect. Bachelor of Science in Computer Engineering and Bachelor of Science in Agricultural Engineering. Cavite State University, Indang, Cavite. April 2005. Adviser: Mr. Jaime Q. Dilidili and Co-adviser: Mrs. Marivic G. Dizon.
The "Design and Testing of a Microcontroller-based Sweetened Yam Mixer" was conducted at Brgy. Buna Lejos, Indang, Cavite. The general objective of the study was to design, test, and construct a functional microcontroller-based sweetened yam mixer. The system was composed of two main parts: specifically, the machine, and the controller part. The machine part was composed of stainless steel mixing bowl, stainless steel blade with attached Teflon paddle, speed reducer with 1:30 speed ratio, support frame, and 1.5Hp single-phase AC motor. The controller part was composed of the control unit, clamp meter and contactor, push buttons: switch, start, stop, reset, and set values for the time in terms of minute and hour, on/off switch, power supply, and a 16 x 2 LCD. The microcontroller-based sweetened yam mixer can operate depending on the real time clock that was set upon by the user. Automatically, the clamp meter sensed the current of the AC motor and the current produced was eventually displayed on the LCD. The cooking time of the yam mixer should correlate with the current- depending on the load of the machine. And when the operation meets the parameters that are time and current based, the operation would automatically stop.
The preliminary evaluation was conducted at Brgy. Buna Lejos, Indang, Cavite together with their advisers and technical critics. The final evaluation of the design took place at the Food Processing Center at the Cavite State University on February 3-4, 2005. The whole system underwent a series of testing and evaluation through pilot testing and data gathering. The results were as follows; for 40 kg load, the cooking time was 1 hour and 45 minutes; for 20 kg, the cooking time was 1 hour and 30 minutes; and for 10 kg load, the cooking time was 45 minutes. The moisture content was found to be 48.6%MCwb for 2 hours and 30 minutes cooking time at the maximum load of 40 kg. As time of cooking increases the moisture content of the mixture decreases and resulted to an increase in the mixture's viscosity. The sweetened yam mixer successfully mixed a certain amount of the "jalea de ube" product together with the automated function of time and current that was used as parameters for evaluation. The evaluation of the system was favorable when the cooked "ube" quality was observed such as uniform mixture consistency and the absence of burnt product in the mixture. The testing of the system confirmed that the system had a great advantage over the manual operation of mixing "jalea. de ube".
