This spray warm and cooling machine, also named tunnel pasteurizer, which is different from the direct heat method (instantaneous sterilization), tunnel pasteurizer sterilize products and containers together, so that you bottle eliminate various possible causes of the growth of harmful bacteria within the allowed time.
Liquid and its package are heated to the required sterilization temperature and maintained at that temperature for some time, and then down to ambient temperature.
This machine contains 8 temperature zones, the minimum temperature difference between zones confirms good sterilizing effect, and also reduce bottle broken rate. Hot water is recycled to use in temperature sections in order to save heat energy and reduce water consumption.
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: used for bottles and bottles.
(1) Water heating 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 about60℃-65℃(according to client’s requirements). 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.
(4) Principle features
1) The frame mainly is structural steel, surface is the stainless steel of 304, and the stainless steel frame of 304, the stainless steel foot margin is adjustable.
2) Optional temperature zones
This equipment has 8 temperature zones, customers bottle choose any one of the temperature zone. Facilitate the adjustment and save cost.
3) Adjustable temperature
On the PLC control panel, one control button bottle control one temperature of each zone.
The customer bottle adjust it into any temperature.
4) Adjustable speed.
It equipped with PLC control panel, customers bottle be adjusted chain board speed.
5) Equipped with waste treatment system.
5.1 PLC Operating floor
5.2 You can see there’s green nylon guard inside the machine, it is better to protect the glass bottles, especially your newly designed cool bottle.
5.3 There are alarm lights on each temperature zones, so when the temperature is 0.1 higher or lower than fixed temperature, the alarm lights on. Confirm good pasteurize temperature.
5.4 All the water tanks are completely welded. Not like other machines in other company, they weld the water tank by several dots, the water leaks a lot. Complete-welded water tanks are good for the water re-use, no water waste.
5.5 We put a pasteurize recorder on the control cabinet. This recorder keeps all the information when the machine works, you bottle also copy the date to your computer for study of the pasteurize skills.
5.6 Emergency stop device
If you need to stop the machine in a very emergency situation, here you can just use this small device to make this machine stop, no damage to the bottles.
