Description

Technical Field

[0001] The utility model relates to the technical field of wine making, in particular to a yellow water flavoring liquid processing system based on esterification reaction and ceramic membrane filtration. Background Art

[0002] Yellow water is one of the main byproducts of the solid-state brewing liquor production process in my country's traditional technology. It has a high viscosity, complex components, and is brown or light brown in color. During the fermentation of the mash in the cellar, a large amount of soluble starch, reducing sugar, aroma substances produced by metabolism, organic acids, etc., as well as long-term domesticated beneficial bacterial flora and bacterial autolyzates are dissolved.

[0003] At present, the main destinations of yellow water are to produce yellow water wine, cultivate artificial cellar mud, mix the dregs or use it for koji making, brew vinegar or prepare organic acid salts and other by-products. In addition, using yellow water to prepare flavoring liquid to adjust liquor is also a major destination of yellow water.

[0004] CN102229879B discloses a perfume liquid and a production method thereof. Specifically, yellow water is mixed with high-temperature Daqu, heated and fermented, filtered and decolorized to obtain the perfume liquid. Although this method can make full use of the nutrients in the yellow water, the quality of the obtained perfume liquid is not high. For example, directly using yellow water from a cellar will result in more impurities; for another example, decolorizing the filtered perfume liquid will reduce the fragrance of the perfume liquid.

First, the yellow water from the cellar enters the pretreatment system 1. The pretreatment system 1 includes a yellow water collection device 11 and a multi-stage filter 12 which are arranged in sequence for filtering the yellow water from the cellar.

[0032] In the pretreatment stage, the yellow water from the cellar is first allowed to stand still. Specifically, a flocculant addition port is provided above the yellow water collecting device 11. The purpose of purification and impurity removal is achieved through the flocculation effect of the flocculant.

[0033] After the standing is completed, the obtained yellow water supernatant still contains small molecular impurities and needs to be filtered. Further, the multi-stage filter 12 includes a double filter 121 and a sand filter 122 connected in sequence. Specifically,

[0034] The double filter 121 is a 60-mesh filter.

[0035] The sand filter 122 is made of quartz sand with a particle size of 0.45 mm to 0.63 mm, an operating pressure of 0.05 MPa, a filter layer height of 800 mm, and a filtration rate of 2×10 -3 m / s.

[0039] Then, the decolorized yellow water supernatant enters the esterification reaction system 3.

[0044] Next, after the esterification reaction is completed, yellow water esterification liquid is obtained, and the yellow water esterification liquid is subjected to ceramic membrane filtration.
