Tower Unit beverage system for BIB concentrate, rapid cooling of mixed carbonated/non-carbonated beverages equipment system. The multiplex soda dispenser is equipped with BIB slurry feeding system, water cooling system, carbonization system and water circulation system. The BIB slurry system is powered by 40psi CO2 gas to pump the concentrated liquid into the facility and cooled by the water cooling system. The carbonization system carbonized the cooled direct drinking water with 80psi food-grade carbon dioxide gas, and mixed the carbonated water with the concentrated solution in a certain proportion after the production. The water circulation system ensures the temperature of the liquid in the pipeline, especially the exposed part between the tower head and the main engine, to ensure the taste of the product.
