PROBLEM TO BE SOLVED: To produce the same product with high efficiency and perform a small not multi-variety production with high efficiency by use of the same device by connecting the outlet piping from the bottom of the tower tank of a tower tank group and the inlet piping from the tower top part of the tower tank group to a piping automatic connection device, and connecting the outlet piping of the piping automatic connection device. SOLUTION: A piping group Lx and a piping are connected to the inlet and outlet of an L:1 piping automatic connection device 1. Pipings are connected to the inlet and outlet of an M:K piping automatic connection device 2. The outlet piping of the L:1 piping automatic connection device is connected to the inlet piping of the M:K piping automatic connection device 2 through a piping 10. The liquid supplied form the piping group Lx to the L:1 piping automatic connection device 1 is supplied to the inlet piping of the M:K piping automatic connection device 2 through the piping 10, and supplied to the tower top of an optional tower of tower tanks A-D from the outlet piping of the M:K piping automatic connection device 2. According to this, a small lot multi-variety production can be placed, and a production plan for performing the same lot production in the shortest time can be formed.
