Performance Evaluation according to the Development of Corn Mill of 200 kg/h for Export to the Philippines

초록

Since rice is the main food in Korea, there are no regulations on corn milling yet. Corn is known as one of the world's top threefood crops along with wheat and rice, and it is known that 3.5 billion people worldwide use corn for food. In addition, corn millsare not developed or sold in Korea, but the use of corn mills is increasing significantly in many countries in Southeast Asia. In thePhilippines, as Korea's rice mill import increases, Korea's KAMICO (Korea Agricultural Machinery Industry Cooperative) and domesticcompany A agreed to develop a corn mill jointly with PHilMech, an organization affiliated with the Philippine Ministry of Agriculture. However, research on corn milling was very insignificant, so the development was carried out based on the technology of Korea's ricemill. Rice milling is performed by peeling off the skin of rice and producing brown or white rice, so it is carried out by removingthe skin and cutting the skin. On the other hand, in the corn mill, the skin of the corn is peeled, pulverized and selected to producemain products suitable for edible use. Therefore, in order to develop a corn mill, processes such as peeling, transfer, grinding, sorting,and by-product separation are required, and suitable parts must be developed. In addition, the performance must be gradually improvedthrough experiments in which corn is repeatedly milled. The Philippines produces 7.98 million tons/year of corn, which is about 100times that of Korea, and is mostly consumed as a staple food. This is about 10% of the total crop production in the Philippines. Inaddition, the main cultivation complexes of corn are the mountainous regions of Tarlac or Pangasinan, and the produced corn is 72.4%of the so-called yellow corn called Arabel and Sarangani, and the remaining 27.6% are known as white corn. In this study, it wasintended to produce grains of 2.5 mm or less suitable for food for yellow corn and to develop a corn mill for 200 kg per hour. Detailedconditions for development are stipulated as more than 55% of the main product recovery rate, more than 31% of the by-product recoveryrate, less than 5% of the raw material loss rate, and more than 80% of the embryo dislocation rate. In this study, to achieve this,the overall process of the corn mill was developed, and the optimal conditions for the corn mill were obtained through the developmentof parts and empirical tests to improve performance. In addition, it was intended to achieve the development goal by evaluating andanalyzing the performance of each part so that it did not conflict.
