Embodiment 1

[0052] Four high-vacuum low-temperature rectification towers are adopted, the tower diameters are 150mm, 100mm, 80mm, and 80mm respectively. The tower equipment and the matching falling film short-range reboiler are all manufactured by Shanghai Research Institute of Chemical Industry. The special packing in the rectification tower And the tower internals are all developed by the National High Efficiency Separation Tower Packing and Device Technology Research and Promotion Center. process such as figure 1 shown. The wine used in the test is a traditional 56-degree liquor of a certain domestic brand, and the ethanol concentration in the original wine is 56% (V / V). The raw wine is sent to the de-alcoholization tower 6 by the pump 2 at a flow rate of 5 L / h, and the de-alcoholization tower top is provided with a de-condenser 7, which is a secondary condenser. After passing through the secondary condenser, the top temperature of the dealdehyde tower is controlled at 5° C., the top...

Abstract

The invention relates to a method and a device for manufacturing pure white spirit. The method adopts a high-vacuum low-temperature multi-tower continuous rectification process to rectify and separate traditional white spirit into aldehyde, liquor, methanol, fusel oil, aromatic substances with low boiling point, pure ethanol and other parts, and to blend the parts into the pure white spirit or vodka again according to requirements; the device comprises an aldehyde removal tower, an alcohol removal tower, an alcohol tower and a methanol tower; and the method has a stable process flow and simple operation. Compared with the prior art, the method can effectively remove the aldehyde, the methanol, the fusel oil and the substances which are harmful to a human body, ensures that the manufactured pure white spirit and vodka have pure taste by reprocessing the traditional white spirit, and provides a practical and effective approach for the optimization and innovation of new-variety spirit for white spirit enterprises.

Description

technical field [0001] The invention relates to a method and a device for producing liquor, in particular to a method for making pure liquor using traditional liquor. Background technique [0002] Liquor is a traditional product of the national industry, and its components are very rich. There are hundreds of aroma substances that have been found, and there are more than 100 known trace components. According to different chemical properties, various fragrance substances are divided into alcohols, aldehydes, esters, orgamic acids, phenols, aminoacids and its compounds. Its representative components are shown in Table 1-Table 4. [0003] Table 1 Typical components of liquor - alcohols [0004] serial number name molecular formula Boiling point °C 1 Methanol CH 4 o 64.51 2 ethanol C 2 h 6 o 78.32 3 n-propanol C 3 h 8 o 97.2 4 Butanol C 4 h 10 o 117.7 ...
