Tunnel pasteurizer is a large stainless steel cabinet. The filled and closed bottles are entering on the conveyor from one side of the housing (bottles can be placed in crates or pallets) and the other side are leaving the pasteurizer cooled with cold water at the initial temperature of about 20 ° C.
Heated bottles filled to the desired temperature start after entering the first section of the pasteurizer. Gradually, as the containers pass through the pasteurizer, the temperature is raised to pasteurization temperature of 60-80 ° C. Beer is kept at this temperature after a certain period. After completion of the bottles cool pasteurization and leaving the pasteurizer.
The advantage of this solution is the pasteurization of beer along with the packaging. The disadvantage is less reliable pasteurization and large size of the device.
Tunnel pasteurizer consists of :
Hot water circuit with plate heat exchanger
Spray a watertight pasteurization tunnel
Pumps, control valves, pneumatic valves
Buffertank incl. sanitation pump
Pipe connections and fittings
Belt or roller conveyor
Electrical cabinet with the control system
The main advantages of tunnel pasteurization:
Current pasteurization of beverages and packaging
On one line can be pasteurized more kinds of beverages
Qucik start
Can be used as a heat sink for other devices
The best way to pasteurize beer bottles and cans is to process the already-packaged product. Beer is filled into bottles or cans, sealed and then moved to a tunnel pasteurizer. Basically, the machine sprays high-temperature water jets on the bottles, stabilizing the beer inside them and neutralizing unwanted microorganisms.
