SOLVENT FORMULATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a solvent formulation system which can prevent contamination of an infinitesimal amount from other compositions or respective raw materials, can automatically formulate many kinds of compositions and also can be accommodated to small amount production.SOLUTION: A solvent formulation system includes: a plurality of raw material containers 31, 32 to 3n; a plurality of supply passages 41, 42 to 4n which controllably supply raw material solvent from the respective raw material containers; a plurality of supply nozzles 51, 52 to 5n which eject the raw material supplied from the supply passages; a mixing container 2 in which the raw material solvent is stored and mixed; a mass measuring device 6 which can measure a mass of the mixing container; and a control device 8 which is connected with them. The supply passages and the supply nozzles exist independently corresponding to the respective raw material containers. The control device 8 controls the related supply passages and supply nozzles so as to supply necessary raw material from the respective raw material containers in accordance with composition determined by measuring the mass of the mixing container. The contamination by means of the container or the like is prevented by using a packing container for packing a product as the mixing container.
