Drying machine and film producing method from solution

Provided are a drying machine and a film producing method from solution. A belt (91) is composed of a belt-like central part (91c) and belt-like sidepieces (91s) arranged at both sides of the belt-like central part (91c) in the width direction thereof. The central part (91c) and the welding part (91w) of the sidepieces (91s) expose from a surface (91a). The concentrated liquor flows out from an outlet port (133a) to the surface (91a) of a moving belt (91). A curtain coating film (136) is made of the concentrated liquor by covering the welding part (91w) upon the surface (91a). The drying wind is vented from the pipe to the curtain coating film (136). The solvent is evaporated from the curtain coating film (136) by contacting with the drying wind. The heating wind (150) is blown to the welding part (91w) from interior via a nozzle (151). The solvent, via the heating wind (150), is evaporated from the curtain coating film upon the surface (91a). A peeling roller peels the curtain coating film (136) off the belt
