NOVELTY - Precipitate board manufacturing apparatus (20) has container (22), heating unit (23), process chamber (24), coolant carrying-in and taking-out anterooms (26,27), conveying unit (29), immersion unit (30) and material replenishment unit (31). Container contains melt solution (21) of metal material or semiconductor material. Anteroom (26) supplies coolant (25) to chamber interior, and anteroom (27) ejects coolant to chamber exterior.    USE - For manufacturing precipitate board e.g. polycrystalline silicon wafer used for solar cell, which generates electric power.    ADVANTAGE - The manufacturing apparatus is economical and has improved working efficiency and simple structure. The apparatus stably provides compact precipitate board with excellent quality. The material replenishment time is shortened and production capacity of precipitate board is improved. The thickness fluctuation of precipitate board by individual difference of coolant is suppressed at high precision.    DETAILED DESCRIPTION - The precipitate board manufacturing apparatus (20) has a container (22), a heating unit (23), a process chamber (24), a coolant carrying-in anteroom (26), a coolant taking-out anteroom (27), a conveying unit (29), an immersion unit (30) and a material replenishment unit (31). The container is stored with melt solution (21) of metal material or semiconductor material. Heating unit heats the materials in the container. The process chamber has container in interior space. Anteroom (26) supplies a coolant (25) to process chamber interior, and anteroom (27) ejects coolant to chamber exterior. Conveying unit takes out coolant from process chamber to taking-out anteroom and exterior space, when coolant is carried-in to anteroom (26) and process chamber from exterior space. Immersion unit immerses the coolant to the metal solution, and pulls up. The replenishment unit replenishes the material before melting in the container.
