AI Technical Summary

Problems solved by technology

It can be seen that dissolved oxygen will destroy the colloidal balance in the blended mature wine solution, affecting the quality and taste of the wine. Even if the blending is adjusted repeatedly, the seasoning, physical and chemical indicators, quality and taste of the wine still have great uncertainty

Embodiment Construction

[0017] In conjunction with the accompanying drawings, the non-limiting embodiments are described as follows:

[0018] The concentration of dissolved oxygen in the wine after blending is 50ppm, which is reduced to 50ppb after treatment.

[0019] 1. Parallel flow

[0020] Use a static mixer or filler to mix hydrogen into the wine, and mix 0.2-0.5M per ton of wine 3 hydrogen.

[0021] The wine liquid mixed with hydrogen is sent into the tower from the upper end of the deoxygenation tower 1, flows through the n-Cu alloy catalyst layer 2 and the Pt catalyst layer 3 in sequence, and stays on the catalyst layer for 3-30 seconds. Finally, it flows out from the bottom of the deoxidation tower 1 and is sent to the packaging workshop.

[0022] 2. Countercurrent type

[0023] like figure 1 As shown, the hydrogen is first sent into the tower from the lower end of the deoxidation tower 1, and then the wine liquid is sent into the tower from the upper end of the deoxygenation tower 1, ...

Abstract

The invention relates to a catalytic reduction method for removing dissolved oxygen from wine, taking hydrogen as a reducing agent. The hydrogen is mixed with wine liquid by a way of cocurrent flow or a way of countercurrent flow, then the dissolved oxygen in the wine liquid is deoxidized into water with the catalytic effect of Zn-Cu alloy and Pt catalysts, so as to stabilize the quality and taste of the wine.

Description

1. Technical field [0001] The invention relates to a method for stabilizing the quality of liquor, in particular to a catalytic reduction method for removing dissolved oxygen in liquor. 2. Background technology [0002] Wine is divided into two categories in terms of manufacturing process: brewed wine and distilled wine. [0003] Brewing wine: raw material fermentation → pressing and filtering → aging storage → blending and filtering → finished product filling, typical representatives include Chinese rice wine, Japanese sake, wine, etc. [0004] Distilled wine: fermentation of raw materials → mother mash distillation → aging storage → blending and filtration → filling of finished products, typical representatives include Chinese liquor, vodka, brandy, whiskey, etc. [0005] Generally, wine will be stored and cellared for 1 to 3 years or even longer after brewing, pressing or distillation. During this period, different wines have different storage containers, such as oak ba...
