Craft Brewery Automated Bottling Machine Beer Tunnel Pasteurizer 1
GD-SJ- series Tunnel Pasteurizer is also called water spraying type
bottle warming/cooling machine. Different from directly heating
type sterilizing machine, this series Tunnel Pasteurizer could
sterilize liquid product together with its package (can or PET
bottle or glass bottle). It can kill all bacteria which possible
exist 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
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.
(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 is about
65℃. 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, a tap water
cooling-area and cooling water cooling-area. There is one water
tank under tap water cooling area.
Tap water is pumped into nozzles above mesh belt and atomized onto
Cooling water cooling zone use cooling water which has been reduced
to 10 degrees temperature,
In order to ensure the machine temperature reaches yogurt drink
