DEVELOPMENT A PROTOTYPE OF MOLDING EQUIPMENT FOR FORMING PRODUCING INSTANT KHAO YAKU BASED ON LOCAL CUTURAL FOOD

Abstract

The objective of this research is to develop a prototype molding equipment to be used as a mold for producing ready-made yaku rice based on the wisdom of using local tools. By studying information on the design of prototype structures, forming equipment and molds for forming yaku rice. By applying the community's wisdom about making food molds together with mechanical technology. The machine consists of 3 components: 1) a supporting structure for the mold set for forming yaku rice, 2) the mold set has 2 parts: the lower mold set and the upper mold set. There are 20 rectangular shaped compartments for packing yaku rice, 3) a Heating using a heater with an electrical power of 1,000 watts using Alternating current (AC). The testing method to determine suitable conditions for forming yaku rice. Put 1 kilogram of yaku rice into a mold and then cook. extrusion press At 4 temperature conditions of 150, 160, 170 and 180 degrees Celsius. the holding times are set at 3, 5 and 7 minutes.

            The test found that the most suitable temperature for forming yaku rice is 180 degrees Celsius, the most suitable and acceptable hold time is 7 minutes. The yaku rice pellets have the greatest swelling at the thickness level. 18.72 millimeters and the moisture percentage is at the level of 8 %. The yaku rice pellets will have the appearance of yellow rice and the swelling rate is at the highest level. The machine could produce 171 pieces per hour. Engineering economic analysis of prototype molding equipment and molds for forming yaku rice. There is a break-even point of 1,048.49 pieces per year, with a payback period of 0.14 years or 52 days. Results of the satisfaction assessment with a prototype of forming equipment and molds for forming yaku rice. The overall average score of 4.29, indicating a high level of satisfaction.
