CJ Corporation's management decide to move its entire flour mill in Busan, South Korea becausethe company needed more space to increase capacity. They made the move after increasing its capacity and updating it,said Switzerland-based Buhler, which was involved in the relocation project.
Pusan, located in the southeast of the Korean peninsula facing Japan, is South Korea's second-largest city anda major port. Korean CJ Corporation built its first flour mill in Pusan in 1955.
Later, the company expanded the plant to four grinding lines with a combined processing capacity of1000 metric tons of wheat per 24 hours. As the mill grew, logistics and environmental protection problemsincreased, Buhler said in a release describing the project.
When another CJ mill increase became necessary, management decided the only option was to construct a new facility onanother available site in Yangsan City, 30 kilometers away, while reusing existing plant components.
The decision was made in 2002. The large-scale mill transfer was planned as a coordinatedeffort between members from an architecture firm, local vendors for supplying various ancillary components, and Buhler as supplier of the new and "old" flour mills.
The project involved the construction of a flour mill with three lines, one with a capacity of 500 and two with a capacity of450 metric tons of wheat per 24 hours. This increased the total capacity of the original CJ mill to 1400from 1000 tonnes per 24 hours.
The 500-tonne line was constructed from scratch. For the two 450-tonne lines, some existing plantcomponents from the Buhler mills in Pusan were used, Buhler stated.
"All the used parts were completely reconditioned and retrofitted to the state of the artthrough the incorporation of new machine elements and components," Buhler stated. "Also newwere the entire pneumatic and mechanical conveying systems and dust collection filters."
The project got underway in February 2003, with the operation of the first first milling line along witha wheat storage elevator with a capacity of 19,000 tonnes. The large finished product bulk storage systemwas also completed by June 2005. The second milling line followed in July 2005, the third in October of the same year.The inauguration ceremony took place on 31 March.
Flexibility received the utmost attention in the design, defining the flow charts of the three milling lines,Buhler stated.
Each line is capable of producing four different flour types simultaneously. For the plant as a whole, this meansthat 12 different flour types can be made concurrently.
The three lines of the CJ mill make flours for producing fresh pasta, cookies, cakes, and bright bread loaves.
CJ Corporation's plant includes over 70 different flour grades, produced from up to six different wheat varieties.
