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.
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
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
