The present application belongs to the technical field of processing of by-products of brewing, and specifically discloses a method and device for reducing viscosity of distiller's grains based on enzyme treatment, which comprises the following steps: S1, dispersing the distiller's grains of liquor and mixing the auxiliary materials by means of a stirrer; S2, adjusting the pH of the uniformly dispersed and mixed distiller's grains by means of ammonia water, and then adding enzyme hydrolysate, and performing enzymolysis for 24 hours; and S3, further adding decomposition enzyme to perform enzymolysis into sugar. The method and device for reducing viscosity of distiller's grains based on enzyme treatment are used to disperse the distiller's grains and mix the auxiliary materials by means of the inner rotation and outer rotation modes of the stirrer, and to reduce the viscosity of the distiller's grains by means of a two-step enzyme hydrolysis method, so that the viscosity of the distiller's grains is reduced and the saccharification rate of the distiller's grains is improved, thereby laying a foundation for further fermentation of the distiller's grains to produce protein.

The invention discloses a low-temperature evaporation device for wastewater treatment, relates to the technical field of low-temperature evaporation, and aims at the basic principle of wastewater low-temperature evaporation to optimize the circulation process of wastewater, specifically, a wastewater laminar flow circulation mode is formed by utilizing each group of fixed conical caps and movable conical caps; the relative positions of the fixed conical cap and the movable conical cap in the evaporation kettle are further limited, so that a relatively independent and closed laminar flow bin is formed in the evaporation kettle, and the purpose is that the vacuum degree in the laminar flow bin can be more directly controlled to promote the low-temperature evaporation process; in combination with the structure, wastewater circulation is controlled according to the vacuum degree in each laminar flow bin and the pressure numerical value of the wastewater in the corresponding laminar flow bin in the operation period by utilizing the influence process between the vacuum degree and the pressure numerical value, and the essence is that sustainability and stability in the low-temperature evaporation process are maintained; and the solute concentration in the wastewater does not need to be directly associated.
