Yellow wine rice milk reusing method

Abstract

The invention discloses a yellow wine rice milk reusing method. The method comprises the following steps of: a, guiding rice milk obtained by soaking rice in a yellow wine brewing process to a storage tank for storage, and placing the rice milk for certain time so that certain sediments settle naturally; b, introducing the naturally settled water in the storage tank into a container for placing a cylinder; c, adding a flocculating agent into the water incompletely consumed in the step b into the storage tank, and introducing the settled clear water into the rice soaking container; and d, introducing the silt obtained by settling in the step c out for brewing wine or animal feed. In the step a, the rice milk is placed in the storage tank for 36 to 48 hours. According to the yellow wine rice milk reusing method provided by the invention, the rice milk generated in the yellow wine brewing process is reused, the consumption of the flocculating agent is greatly reduced, the cost is saved, and the environment is protected; and because the generated rice milk is not directly discharged to the external environment, zero discharge of rice milk pollutants is realized.

Description

technical field [0001] The invention relates to a method for purifying and reusing waste water in a food manufacturing process, in particular to a method for reusing rice wine rice milk water. Background technique [0002] The existing domestic rice wine factories mainly have two treatment methods for the rice milk water produced in the brewing process of rice wine: direct discharge or discharge after adding flocculant. Although the cost of direct discharge is low, it will cause serious environmental pollution; adding flocculant The post-discharge rice milk water treatment effect is good, but the cost is high, and the precipitated substances are generally discharged without utilization, and its high pH will have a certain impact on the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for reusing rice milk water from yellow rice wine, reusing the rice milk water produced in the process of brew...
