The invention discloses a saccharification integral machine device for self and laboratory brewing of beer and relates to the field of beer fermentation engineering and equipment. The device comprisesa machine body, a stirring mechanism, a wheat juice filtering mechanism, a temperature control mechanism, a distillers' grain discharge mechanism, a distillers' grain washing mechanism, a backwash mechanism and a wheat juice collection mechanism, wherein the stirring mechanism is positioned at the bottom inside the machine body; the wheat juice filtering mechanism is arranged in a position whichis 2cm from a part above the bottom of an inner cylinder of the machine body; the temperature control mechanism is used for detecting and controlling temperatures inside the machine body; the distillers' gain discharge mechanism is fixed at the bottom of the inner cylinder of the machine body; the upper part of the distillers' grain discharge mechanism is parallel to the surface of the wheat juicefiltering mechanism; the distillers' grain washing mechanism is arranged at the top of the inner cylinder of the machine body; the backwash mechanism is fixed at the bottom inside the machine body; the washing direction appoints to a part below the distillers' grain discharge mechanism; and the wheat juice collection mechanism is communicated with the bottom of the machine body. Automatic controlon temperatures expected at saccharification and boiling stages can be met, meanwhile, cleanliness and sanitation are achieved, the problem of over-cooking of wheat juice is avoided in the wheat juice saccharification process, the process quality of beer saccharification and boiling is improved, and the taste of the beer can be improved.
