Production apparatus of sugar solution and production system of sugar solution

Abstract

A sugar solution production apparatus includes a saccharification tank that obtains a saccharified solution containing a solid substance from a cellulose-containing biomass, a solid-liquid separator that separates the solid substance from the saccharified solution to obtain a sugar solution, an enzyme recovery solution tank that stores an enzyme recovery solution, a sugar solution extraction line that extracts the sugar solution from the solid-liquid separator, a warm water supply unit that supplies warm water to the solid-liquid separator, an enzyme recovery solution supply line that supplies the enzyme recovery solution from the enzyme recovery solution tank to the solid-liquid separator, an enzyme recovery solution recovery line that feeds the enzyme recovery solution containing the saccharifying enzyme recovered from the solid substance to the enzyme recovery solution tank, and an enzyme recovery solution return line that returns the enzyme recovery solution to the saccharification tank.
