Embodiment Construction
[0029] A kind of preparation method of molasses comprehensive utilization described in the embodiment of the present invention 1, this preparation method comprises the following steps:
[0030] (1) Prepare the medium, prepare the molasses culture medium A tank, B tank and C tank, and prepare the yeast fermentation inoculum at the same time;
[0031] (2) Fermentation is carried out, and the fermentation is divided into three stages, such as figure 1 As shown, they are:
[0032] The first stage: Inoculate Saccharomyces cerevisiae into 20°-35°Brix (Bx) molasses culture solution A tank, ferment at 30°C-35°C and pH4.5-5.5, the inoculation amount is 5%- 10%, when the residual sugar content is lower than 15°-20°Brix (Bx), the alcohol concentration reaches 8%-10%, and enters the second fermentation stage;
[0033] The second stage: the first-stage reaction solution is introduced into the molasses culture medium B tank, inoculated with fission yeast and Aspergillus oryzae, the inocul...
