Yuqi wine produce more than 30 kinds of double deck, Yuqi series of yellow wine. In recent years, on the basis of adhering to traditional brewing techniques, the company has reformed its equipment and is committed to researching and developing refreshing yellow wine that suits modern consumers' tastes. In response, ZOZEN boiler provided a 4-ton WNS condensing gas-fired boiler. The condensers at the rear of the boiler adopt finned tubes to increase the heating surface and improve the heat transfer efficiency. The fin tube is made of ND steel and can effectively solve the issue of low temperature corrosion of steel. After the restructuring, Yuqi Liquor produced about 25,000 tons of yellow wine and 3,000 tons of white wine, which greatly increased production efficiency.Harbi
