Embodiment Construction
[0018] The content of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] Embodiment (using cassava as raw material):
[0020] Such as figure 1 As shown, the cassava flour is sent to the batching tank, the batching water is the liquid phase material from the secondary separator, amylase is added for enzymolysis treatment, and the material after enzymolysis is sent to the preheating tower for two-stage preheating, and then sent to To the jet liquefier, after being liquefied by jet, it is sent to the maintainer for a period of heat preservation, and then sent to the first-stage separator for liquid-solid separation, and the liquid phase separated by the first stage is sent to the continuous sterilizer for sterilization treatment, and then sent to the to the flash tank for three-stage flash evaporation, and the flash-evaporated material is sent to the saccharification tank; after the material is s...

The invention discloses a liquefaction and sand removal process for producing ethanol through fermentation by using potatoes as raw materials. The liquefaction and sand removal process comprises the following steps of: crushing the raw materials, feeding the crushed raw materials into a proportioning tank, proportioning the materials by using a liquid phase separated by a secondary separator as proportioning water, conducting enzymolysis, feeding the enzymolyzed materials into a preheating tower for preheating, feeding the preheated materials into a jet liquefier, feeding the liquefied materials to a primary separator for liquid-solid separation, feeding a liquid phase separated by the primary separator into a continuous disinfector for disinfection treatment, then feeding the materials into a flashing tank for flashing, feeding the flashed materials to a saccharification tank for saccharification treatment, cooling the saccharified materials to a cooler for cooling and feeding the cooled materials for fermentation; and feeding a solid phase separated by the primary separator into a washing tank for washing, feeding the washed materials into a secondary separator for liquid-solid separation, feeding a solid phase separated by the secondary separator to a drying section and feeding the liquid phase separated by the secondary separator into the proportioning tank for proportioning. In the entire liquefaction and sand removal process for producing ethanol through fermentation by using potatoes as raw materials, sand is removed through two stages of separation, heat and water are effectively used, and the goals of removing sand, saving energy and saving water are achieved.
Description
technical field [0001] The invention belongs to the technical field of ethanol production, and in particular relates to a liquefaction and sand removal process for producing ethanol by fermenting potatoes as raw materials. Background technique [0002] With the shortage of petrochemical resources and the aggravation of energy crisis, the development of fuel ethanol and biofuel is an important direction of my country's energy development. Initially, the raw materials for the production of fuel ethanol in my country were mainly corn and aged wheat, but with the expansion of production scale and the rapid development of other grain deep processing, the aged grain has been exhausted, and the grain supply has begun to tighten, and the country has urgently stopped Some projects use corn as raw material, so it is of great significance to vigorously develop ethanol processing projects using non-grain crops such as potato (including cassava and sweet potato), sweet sorghum and straw a...
