Spraying Type Packing Production Line Tunnel Pasteurizer For Beer Or Beverage


Brief introduction
GD-PLG series Tunnel Pasteurizer 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.
Ⅱ. Main technical parameters
(1) Total capacity: 10 000bottles/hr.

(2) final temperature at exit on the machine: 30~35℃ (for beer)

(3) total power of motors: 27kw

Power of speed reducer on mesh-belt conveyor: 1.1kw

Power of speed reducer on bottle input conveyor: 0.37kw

Power of speed reducer on bottle output conveyor: 0.37kw

Power of centrifugal pumps (8sets): 3×8=24kw

(5)Net weight of the machine: about 6900kg

(6)Overall dimensions: 19000×2100×2040mm

Ⅲ. 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 on GD-SJJ-4000Tunnel Pasteurizer:

  • Water heating section:

There are eight 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.

(1)Constant temperature section (sterilizing section)
This section is sterilizing section, which temperature is about 60℃. 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 angle seat 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.

(2)Cooling section
This section consists of warm water cooling-area and tap 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 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. Because this machine is too long, we have divided it into two parts to transport it. The user could assemble them into an integrated unit at his workshop. The user shall install the whole machine on a hard & level ground. And then install all spray pumps, water pipelines, motors and all speed reducers.

2. Install bottles input / output conveyors. Regulate pectinate plates to level mesh belt, in order to assure bottles input or output smoothly.

3. Connect steam pipelines, compressed air pipelines (0.4~0.6Mpa) and water pipelines.

4. Connect power cables, electric control circuits and instrument circuits.

5. Add lube into speed reducers. The Infinite Speed Reducer shall use UB-1 brand of lube.

6. There are 16 sprocket wheels on square driving shaft and 8 sprocket wheels on rear shaft. Only one sprocket wheel is fixed at central point of shafts in axle direction. All other sprocket wheels are arranged in proportional spacing on shafts and movable in their axle direction, in order to compensate heat expansion of mesh belt, keep a good joggle work between mesh belt and sprocket wheels.

7. Individually start motors for mesh belt conveyor, bottle input/output conveyors and pumps in short time, in order to check correctness of revolving direction of all motors.

8. Start mesh belt conveyor to run it for about 30 minutes at lower speed. Check the mesh belt if it is running smoothly. And then accelerate its speed gradually to rated speed according to sterilizing time required. Demarcate speed of mesh belt as per different products.

9. Start bottle input/output conveyors. Check them if they are running smoothly. Regulate their running speeds according to actual outputs.

10. Tap water is compensated into water tanks in the machine one by one through pipelines at cooling section. When water level reaches to certain overflow port, start all spray pumps, in order to check all nozzles if they are blocked, check water-atomizing condition.

11. Turn on valve on compressed air pipeline. Regulate pressure reducer to keep air pressure at 0. 4Mpa.

12. Set sterilizing temperature and temperature alarm (upper limit temperature and lower limit temperature) by regulating Temperature Control System in accordance with process requirement. Turn on steam valve and regulate parameter on PID instrument (In general, this parameter has been set before delivery), in order to stabilize water temperature within ±1℃ around set point (temperature).

13. Heat water in water tanks to temperature required.

14. Stop all motors and turn off air valve, when all regulating works have been finished.

Ⅴ. Operation and Maintenance
A. Operation
1. Illustration for panel function
Temperature setting button I: this button controls steam magnetic valve at 1st water tank in heating section.

If water temperature is less than setting point about 1℃ (It has been set by manufacturer), the steam magnetic valve is turned on to heat water. If water temperature is higher than setting point about 1℃ (It has been set by manufacturer), the steam magnetic valve would be turned off to stop heat.
Remark: If you need to reset water temperature, you could press q or p buttons on Temperature Controller panel to reset it under Running Mode. The SV indication area (temperature setting value) is glinting when you reset the value. Press【SET】button to enter a value if displayed value is suitable. Please read Instrument Manual for Temperature Controller carefully before you need to modify other parameters.
