The invention discloses a
solid fermentation tank as well as a method for preparing red kojic rice by using the
solid fermentation tank and a product prepared by the method, and belongs to the technical field of biological
fermentation. The
solid fermentation tank comprises a horizontal fermentation bucket, a temperature detecting opening, a
humidity detecting opening, a pressure detecting opening, an
inoculation opening, a sampling opening, a feeding hole,
sight glass, an inlet
pipe, an outlet
pipe, a balance plate, a rolling bracket, a material baffle and an outside-bucket jacket. The method is used for preparing healthy nutritional red kojic rice by using the solid fermentation tank by the following steps: soaking materials; washing the materials;
steaming the materials; cooling; separating; inoculating; mixing; keeping the temperature; keeping the
humidity; fermenting; harvesting; and
drying and the like. By virtue of the design of the invention, the
environmental protection property, economic efficiency and stability of the solid fermentation tank as well as the homogeneity of the same batch of fermentation products are improved; the solid fermentation tank is applied to the preparation method; the preparation condition is optimized; the contents of
red rice protein,
red rice polysaccharide,
ergosterol and
amino acid in the prepared red kojic rice are respectively not lower than 3.0%, 2.0%, 1.0% and 1.0%; the limit amount of
citrinin is not higher than 0.01mg / kg and the limit amount of
monacolin K is not higher than 0.01%.
