Tunnel pasteurizer
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
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.
(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 bottles.
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 requirements.
