A continuous sterilizing apparatus circulates, through members constituting a flow channel, a sterilizing medium that sterilizes the members to sterilize the members, circulates a sterilizing liquid subjected to sterilization treatment through pipes, performs a series of pieces of treatment including heating treatment, holding treatment, and cooling treatment on the sterilizing liquid, controls a flow rate, a temperature, and a pressure to be preset conditions, and switches a liquid to be circulated through the flow channel from the sterilizing liquid to a liquid to be sterilized.

Method of operating continuous sterilizing apparatus, continuous sterilizing apparatus, fermenting system, and continuous fermenting system

An apparatus that produces a sugar liquid by a method including hydrolyzing cellulose includes a hydrolysis tank to which a recovered enzyme feed pipe and a fresh enzyme feed pipe are connected; a device for solid-liquid separation of a hydrolysate; a sugar liquid-retaining tank having a water supply pipe that washes an ultrafiltration membrane and/or removes recovered enzyme retained in a circulation pipe; and an ultrafiltration membrane device that separates enzyme and a sugar liquid.

Apparatus that produces sugar solutions from cellulose

A method produces a sugar liquid by repeating a sugar liquid production process including (1) to (3): (1) adding a filamentous fungus-derived cellulase to cellulose to perform primary hydrolysis; (2) adding a fresh filamentous fungus-derived cellulase to the hydrolysate in Step (1) to perform secondary hydrolysis; and (3) subjecting the hydrolysate in Step (2) to solid-liquid separation to obtain a sugar liquid, from which a recovered enzyme is obtained; wherein the recovered enzyme obtained in Step (3) is used for Step (1) of the next and later sugar liquid production processes.

Manufacturing method for sugar solution and device for same

A method produces a sugar liquid by adding a filamentous fungus-derived cellulase to a pretreated product of cellulose to obtain a hydrolysate; adding waste molasses to said hydrolysate to obtain a mixed sugar liquid; and subjecting said mixed sugar liquid to solid-liquid separation and filtering the obtained solution component through an ultrafiltration membrane, to recover the filamentous fungus-derived cellulase as a non-permeate and to obtain a sugar liquid as a permeate.

Method for producing sugar solution

A method of hydrolysis of cellulose uses a filamentous fungus-derived cellulase as a carbohydrase and includes adding the carbohydrase to cellulose to perform primary hydrolysis and then subjecting the primary hydrolysate to solid-liquid separation into a primary sugar liquid and solids; adding water to the solids and performing secondary hydrolysis, followed by subjecting the secondary hydrolysate to solid-liquid separation into a secondary sugar liquid and a residue; and filtering the primary sugar liquid and/or secondary sugar liquid through an ultrafiltration membrane, and recovering the carbohydrase from the feed side and recovering a sugar solution from the permeate side.
