Carbonated beverage filling is a filling form that is higher than atmospheric pressure, which can be divided into two types: one is that the pressure in filling tank is equal to the pressure in the empty bottle, and the filling depends on the self-weight of the liquid into the bottle, which is called isobaric filling; the other is that the pressure in filling tank is higher than that in the bottle, and the liquid flows into the bottle by pressure difference, and the high-speed production line adopts this method. Carbonated bottling machine is suitable for filling carbonated liquids, such as beer, soda, sparking water, champagne and so on.

Carbonated drinks, also known as carbonated soda water, are soft drinks filled with carbon dioxide gas. Most carbonated drinks are made with carbonated water and syrup (using drink carbonation machine). When drinking, there are many and delicate foams, such as Coca-Cola, Pepsi customers, sparkling water, soda and so on.
The production of carbonated drinks began at the end of the 18th century, and at the beginning of the 19th century, its predecessor was natural aerated mineral water, and then with the synthesis of artificial flavors, the manufacture of liquid carbon dioxide, the invention of crown lid and the emergence of mechanized production equipment, carbonated beverages were industrialized and produced on a large scale in Europe and the United States, and quickly spread to the whole world.
Now it has become a necessity for people at the end of summer and is loved by the majority of consumers.

CSD bottle filling system is mainly composed of filling tank assembly, cylinder lifting device, cam lifting device, bearing assembly, transmission assembly, filling valve and other components. In the equipment, it plays the role of filling materials into bottles; parts in contact with liquid are made of high-quality stainless steel and other special materials, which meet the requirements of food hygiene.

Filling time allocation table

The Filling tank assembly is an important part of the filling system, which is used to store liquid temporarily before filling, and the internal pressure makes the pressure in the tank consistent with the pressure in the bottle. When working, the material flows into the filling tank through the liquid inlet pipe of the lower distributor, and the lower distributor is used for the liquid inlet and CIP liquid, and is equipped with a dynamic and static seal. The upper part is equipped with an upper distributor, which is mainly used for the entry of CO2 gas and compressed air, and there is also a static and dynamic seal inside. The filling tank upper cover is equipped with a liquid level float, a thermometer and a pressure gauge, which are used to control the liquid level, detect the material temperature and observe the pressure in the filling tank.

The control ring assembly is mainly used for the switch of the filling valve during filling process, and the whole assembly is composed of a ring and several parts. Item 1 is a filling valve opening device, and when a bottle is detected, the cylinder pushes the handle to open the filling valve. Item 2 is a filling valve closing device, which is used to close the filling valve after filling is completed. Item 3 is an exhaust device, which is used to remove residual air from the bottle mouth after filling is finished. Item 4 is a cam for centering cover, which is used to control the upper and down of the centering cover.

Cylinder lifting assembly: item 1 pulls down the cam assembly, and the empty station pulls the cylinder down to make the bottle leave the filling valve. Item 2 is a piston rod, its bottom is fixed on the fixing ring of item 5, and item 3 is a piston. Compressed air enters the internal cavity of the piston from the bottom of the piston rod to push the piston upward. Item 4 is a hanging bottle plate, which is stuck in the bottle entering the filling machine, and its size varies according to the diameter of the bottleneck.

The core technology of carbonated beverage filling is filling valve, which is mainly divided into two categories:
(1) Mechanical filling valve.
(2) filling valve of electronic Flowmeter.
The mechanical valve is the same as the electronic valve in the technological process, in the time distribution, the mechanical valve is distributed in the form of rotation angle; the electronic filling valve control is controlled according to the time sequence, and the time to complete each process of the filling process remains the same when the rotational speed changes.

2. Empty bottle pressurization.
3. Isobaric filling.
4. Pressure relief and exhaust.
5. Pull down the bottle.

The characteristics of mechanical carbonated bottle filling valve:
1.There is no other object in the filling tank except the sensor that controls the liquid level, and the disturbance to the material will be greatly reduced. The flow channel of this valve is simple and convenient for cleaning and sterilization.
2. The mechanical filling valve can open the gas and liquid channels separately, and the opening valve is an absolute constant pressure opening valve. at the same time, the change of the valve opening is relatively smooth, and the discharge is stable.
3. Unique opening and closing valve structure, not only can be opened separately (inflatable valve and hydraulic valve), but also has the function of self-locking, opening and closing valves are more reliable.
4. Suitable for filling PET bottles and glass bottles.
5. The mechanical valve is feasible for the filling of aerated beverages at room temperature.

Characteristics of CSD filling valve of electromagnetic induction Flowmeter:
1. The filling valve of electromagnetic Flowmeter is a dynamic metering method, and the filling capacity can be adjusted arbitrarily. Digital technology and full-time program pulse counting control are applied to absolutely ensure the isobaric filling conditions and the filling quality.
2.There are fast and slow filling processes in the filling process, which can effectively ensure the filling quality and accuracy.
3. It is feasible for the filling of aerated beverages at room temperature.
4. It has the function of exhaust pressure retention, which can effectively maintain the exhaust quality after filling.
5. Equipped with complete CIP circuit and control program.
6. The valve can fill carbonated drinks and fruit juice drinks containing preservatives.

1. Absolute constant pressure opening valve, this is the most critical condition, and to achieve equal pressure opening valve must be achieved to open the gas, open the liquid valve independently. If the valve is opened in the case of pressure difference, it is easy to blister instantly, especially in normal temperature filling, the material temperature is higher, the backup pressure of the filling cylinder is high, and it is even more easy to blister, so the key to filling at room temperature is to open the valve at absolute equal pressure to avoid material blistering as far as possible.
2.The filling process should be smooth, the flow rate should be slow, and it is easy to foam if it is too fast.
3. To improve the exhaust quality after filling, it is better to have a return chamber to keep the pressure.
4. As few foreign bodies as possible in the filling cylinder to reduce the disturbance to the material.
5. Constant pressure and liquid level of materials in the filling tank.

Before you decide to produce carbonated drink, you first have to determine the material of your own container, PET bottle, glass bottle or tin can. The next step is to find a way to determine the container specifications, the common ones are 330ml, 500ml, 1L or even 2L. Once the material and specifications of the container are determined, the appropriate filling equipment can be selected from the FESTA model list. If you don’t know how to choose a model, you can also ask a team of FESTA experts to help you do a professional evaluation and give you the best solution.
