Hard Seltzers are mainly composed of water, syrup, carbon dioxide, flavorings, etc. The syrup is produced through a sugar melting pot and mixing tank or mashing tun . After filtration, it is pumped into the syrup tank of the hard seltzer mixer. Simultaneously, sterilized finished water is pumped into the water tank of the hard seltzer mixer. After degassing to facilitate the mixing of carbon dioxide, the water and syrup are proportionally mixed through the ratio system on the hard seltzer mixer to achieve the desired taste.
The mixed materials are then cooled using a plate heat exchanger. At the other end of the plate heat exchanger, it is mainly connected to a glycol water chiller (providing cold water with added antifreeze, with an outlet temperature of around -3°C). Through this heat exchange method, the materials can be cooled to 0°C to 3°C. Finally, the materials are pumped into the carbon dioxide mixing tank of the beverage mixer. Under controlled pressure, carbon dioxide is thoroughly dissolved into the materials, creating hard seltzer carbonated beverages.
