& Beverage Factory
The structure of sterile tank structure:
| 1 | This series of containers has heating and heat preservation
functions, designed, manufactured, tested and accepted according to
GB150-89<<Steel Pressure Vessel Technical Conditions>>. |
| 2 | the volume has a specification of 100L-10000L, and can also be
designed and processed according to the actual needs of customers. |
| 3 | The container insulation material is made of high temperature
resistant and anti-aging integral pearl cotton insulation. |
| 4 | The interface is an international standard quick-loading chuck
type. The inner tank is made of imported 316L or 304. The surface
is polished by Ra≤0.28 m. The outer surface is polished with matt,
mirror, sandblasted or cold-rolled primary color matt. |
| 5 | The tank has a liquid level gauge, air breathing port, thermometer,
inlet and outlet, circulation pump interface, manhole, CIP cleaning
ball, sight glass, light. |
Sterile tank technical operation Process:
1, Steam sterilization of tanks and valve blocks
All tanks and tubing in contact with the sterile product were steam
sterilized with a steam temperature of 140 ° C and a pressure of
0.27 MPa through two 25 μm steam grade filters. When the tank
temperature rises to 115 ° C and the tank temperature is 140 ° C,
sterilization can begin for 2400 s.
2, Cooling of tanks and valve blocks
After the tank is steam sterilized, the cooling water is
automatically sprayed by the spray pipe in the jacket, and the
temperature of the tank is lowered, and the pressure inside the
tank is lowered. In order to prevent the pressure from falling too
fast, the pressure sensor at the bottom of the tank opens the
solenoid valve and the regulating valve to pass the sterile air
into the tank to maintain the pressure balance of the tank. The
cooling time is 900s.
3, Filling
During the process of filling and discharging materials, the
degassing sterile air enters the upper part of the tank through two
0.22μm air filters and pressure regulating valves, so that the
pressure at the bottom of the tank is always constant, thus
ensuring filling The machine is stably supplied. At the same time,
0.1 MPa of steam is passed through the steam line connected to the
material pipe and the aseptic valve to form a sterile barrier to
ensure the sterility of the filling process.
4, CIP cleaning
The CIP cleaning pipeline is provided with two paths: after the
production is stopped, the operator issues a cleaning command, the
pipeline is connected to the CIP cleaning fluid, and the ball is
cleaned by the rotating cleaning ball at the top of the pipe, and
the tank and the pipeline are cleaned; An organically connected
sterile valve cleans the filler and tubing. Since the inner wall of
the tank body and the pipeline are highly smooth and have no dead
angle, the bacteria cannot stay, thereby ensuring the sterility of
the pipeline.
Firstly, the lye solution with a concentration of 1% and a
temperature of 70 ° C was washed for 5 minutes on the inner wall of
the tank; then the tank was rinsed with cold water for 10 minutes.
If there is scale on the inner wall of the tank, it should be
cleaned with 1% acid solution for 20 minutes, then rinsed with
water to discharge all the liquid.
5, Process control
The entire production process is automatically controlled by the
PLC according to the process requirements.
