Tunnel Pasteurizer is widely used in beer factory to sterilize the beer with the bottle or cans. It is also called water spraying type bottle warming/cooling machine. Different from directly heating type flash sterilizing machine, this series Tunnel Pasteurizer could sterilize liquid product together with its package (glass bottle or PET bottle or can). It can kill all bacteria which possible exists in liquid product or package. Liquid product and its package are heated to sterilizing temperature, keep this temperature for a certain time, and then drop temperature to surrounding temperature by spraying cool water onto package.

2 Working principle

This Tunnel Pasteurizer mainly consists of three sections: heating section, constant temperature section and cooling section. Bottle input conveyor transfers full bottles onto mesh belt from bottle input conveyor. All bottles in the machine are arranged in order and pass through three sections one by one, and achieve requirements of processing technology. At last, bottle output conveyors transfer bottles to discharging chain. Following is description about three sections.

1 Water heating section

There are three separated water tanks in this section. Water is preheated in these tanks by steam. Hot water is pumped into nozzles above mesh belt by spray pump, and atomized onto full bottles. Temperature on bottles is raised gradually in order to reduce loss of flavor in liquid product influenced by high temperature. Recycled water returns to water tanks.

2 Constant temperature section (sterilizing section)

This section is sterilizing section, which temperature can get 80℃ (you can adjust the temperature according to sterilization demand). It is also a constant temperature section. There is one water tank, and water is heated to sterilizing temperature by steam. Hot water is pumped to nozzles above mesh belt, and atomized onto full bottles. A Temperature Control System controls water temperature automatically. Working principle of this system is to regulate flow rate of steam into this tank with a pneumatic membrane valve, on the base of temperature difference detected by temperature control instrument. You could regulate Infinite Speed Reduce to change running speed of mesh belt, in order to change sterilizing time.

Notice: Don’t regulate its speed when the machine shuts down.

3 Cooling section

This section consists of warm water cooling-area and tap water cooling-area. The water tank is under tap water cooling area. . Temperature on bottles is dropped gradually. Tap water is pumped into nozzles above mesh belt and atomized onto bottles. This is final cooling procedure. Recycled water from this area is heated into warm water and is pumped to warm water cooling-area. This is first cooling procedure.

3 Operation

1) Turn on master switch for power supply.

2) Turn on water valve to add water into all water tanks. Be sure to reach water level specified. Turn on compressed air valve.

3) Press temperature control buttons to preheat water in tanks.

4) Set sterilizing temperature and temperature alarm (upper limit temperature and lower limit temperature) in Temperature controller. In general, you just need to set sterilizing temperature.

5) Turn on steam valve manually to preheat water in water tank at cooling section. Water temperature is displayed on thermometer.

6) When water temperature reaches the set point (PV display area), start bottle input /output conveyors to transfer full bottles into this machine.

7) When you finish sterilizing operation, you shall turn off steam valves and water supply valves at first, then stop all spray pumps, at last, stop mesh belt conveyor and bottle input /output conveyors.
