천일염 생산시설의 변화

Abstract

Large-scale pan field farms have developed and expanded from mud flat regions along the west coast of Korea since 1907, the year in which the cultivation of pan field farms was successfully tested. This success may have been mostly the result of solving shortages of labor, increasing the farms’ throughput, and making efforts to upgrade the equality. To identify the main factors behind these advancements, this paper investigates the structural changes that took place in terms of three kinds of aspects: pan field farm structure, attached facilities and the improvement of production equipment. The manufacturers extended the boards in evaporation and crystallization ponds. They spread out environmentally friendly linoleum and tiles on the bottom of crystallization ponds. Then, at an angle of 90°, they used covering board with mud flat tilted at an angle of 60° for the banks of these ponds. In this way, they narrowed break areas, and routed mud flat water into timber boxes in the ponds. With outputs increased by virtue of these changes, the HaeJoo facilities and salt warehouses attached to pan field farms also changed to environmentally friendly materials. The paper discusses the development process of production facilities of pan field farms during a period of about 100 years in Korea. Above all, the most important production facilities are pieces of equipment for moving salt water that changed from man-powered to electrically powered, tools for gathering salt which became lighter in weight, and instruments for conveying salt by man-power that changed from shovels to more convenient salt carts.
