Equipment Introduction
Carbonated soft drinks(CSD) filling machine is particularly suitable for filling and sealing plastic bottles in the beer and Coke, Sprite, soda water, speech water, cocktails, flavored water.. carbonated beverage industry, and can perform secondary exhaust on the bottle body in the filling valve. It can ensure that the oxygen increase of beer is minimized during the filling process.
The filling machine is equipped with 12 to 80 valves, with a production speed of 3,000 to 18,000 bottles/hour and a capacity from 200 ml to 1 liter.
It uses high-precision pneumatic electric filling valves, or mechanical filling valves with double pre-vacuuming, and uses carbon dioxide or nitrogen as counter-pressure gas, without bottles, pre-vacuuming, or filling.
The filling and capping are designed as a whole, using the principle of equal pressure filling. The bottles enter the filling machine through the bottle feeding star wheel, reach the predetermined center of the star wheel, and then the filling valve descends along the supporting cam to center the cans and pre press and seal them.
The sealing pressure is generated by one cylinder in addition to the weight of the centering cover itself. The air pressure inside the cylinder can be adjusted by the pressure reducing valve on the control board according to the material of the can, with a pressure of 0-40KP (0-0.04MPa), At the same time, by opening the pre inflation and back pressure valves, while opening the low-pressure annular channel, the back pressure gas in the filling cylinder rushes into the bottle and flows into the low-pressure annular channel. This process is used to implement a CO2 flushing program to remove air from the bottle, and through this program, the amount of oxygen added during the filling process is relatively minimized.
After the pre charge valve is closed, an equal pressure is established between the bottle and the cylinder. The liquid valve is opened by a spring under the action of the operating valve stem, and filling begins. Through three inlet tanks, the material flows down the bottle wall, and the pre charge gas in the bottle returns to the filling cylinder through the air valve.
When the liquid level of the material reaches the return pipe, the return gas is blocked, filling stops, and an overpressure is generated in the upper gas part of the bottle to prevent the material from continuing to flow down.
Pull the fork to close the gas and liquid valves, and through the exhaust valve, the pressure in the bottle is balanced with atmospheric pressure. The exhaust channel is kept away from the liquid surface to prevent liquid from being carried out during exhaust.
During the exhaust period, the gas at the top of the bottle expands, and the material in the return pipe falls back into the bottle, emptying the return pipe.
At the moment of bottle discharge, the centering cover is lifted by the action of the cam, and under the action of the inner and outer protective plates, the bottle leaves the star wheel and enters the capping machine.
The main electrical components of this machine adopt high-quality configurations such as Siemens PLC and Sike proximity switches. The company’s senior electrical engineers have designed a reasonable configuration form, and the entire production speed can be set on the touch screen according to requirements. All common faults will automatically alarm and provide corresponding fault cause locations. Based on the severity of the fault, the PLC will automatically determine whether the host can continue to run or stop.
