How to carry out the carbonation process before running soft drinks bottling machines

1. The role of carbonation:
(1) Cooling effect
(2) hinder the growth of microorganisms
(3) Highlight the fragrance
(4) It has a comfortable brake taste

2. Factors affecting carbonation effect
2.1 Temperature and pressure
Solubility of CO2 in 100 volumes of water at 1 atm:

Volume numberTemperature (℃)

The solubility of CO2 in water is inversely proportional to temperature and proportional to the pressure acting on the liquid surface.
2.2 Air
1 volume of air removes approximately 50 volumes of CO2. At the same time, the presence of air will cause foaming and gushing during filling.
2.3. Beverage properties
Different types of liquids and the different solutes present in the liquid have a great influence on the solubility of carbon dioxide.

3. Measurement of CO2 Solubility
CO2 solubility is measured as the volume of gas (G.V.) dissolved in water under standard conditions.
Standard state refers to 1 atm, 20°C.
The solubility of CO2 in water in the standard state is approximately 1, and carbonated beverages use this as the unit of solubility, that is, under this condition, the amount of CO2 gas dissolved in carbonated beverages is 1 gas volume (1 G.V.).

National standard regulations:
The CO2 content in cola beverages shall not be less than 3 times the gas volume, and in other carbonated beverages shall not be less than 2.5 times the gas volume.
Internationally, the CO2 content in carbonated beverages is expressed in g/L.
Gas volume multiple × 1.84 = CO2 content (g/L)

4. Measures to improve carbonation effect

Carbonated soft drink filling machinery works by using sophisticated technology to fill drinks like soda, cola, sparkling water, and fruit-flavored water. This advanced equipment is characterized by its smooth operation, safety, easy maintenance, adjustable speed, and high production efficiency.

The machine operates on a micro-negative pressure gravity filling principle which ensures quick, steady, and precise filling. It has a comprehensive material reflux system that can independently return gas during reflux, reducing secondary pollution and oxidation of materials.

The machine uses a magnetic torque type capping head, achieving grabbing and screwing cap functions. The torque for screwing caps can be adjusted continuously, providing constant torque rotary sealing plastic cap function.

The entire machine is controlled using advanced technology such as human-machine interface touch screen control, PLC computer program control, and inverter control. It has automatic control of the cap supply system, automatic detection of filling temperature, high-temperature alarm, low-temperature stop and automatic reflux, no bottle no cap, bottle shortage waiting, cap shortage stop and other functions.

The production process of the fully automatic soda filling line is as follows:

  1. Bottle washing water: The water used for bottle washing is purified water treated by a water treatment system.
  2. Disinfection and arrangement of bottle caps: The bottle caps meeting technical requirements are manually dumped into the automatic disinfection cabinet for disinfection with ozone for a certain time, then manually fed into the cap sorter.
  3. Filling and capping of the product: Materials are filled into cleaned PET bottles through the filling system, and after being capped by the capping machine using sorted caps, they become semi-finished products.
  4. Post-packaging of the product: After filling, semi-finished products become finished products after labeling, shrinking, coding, and film wrapping, and then they are put into storage after manual stacking.

During the production process, some foam will be generated, which will overflow or remain on the machine, causing obstacles and local pollution for the canned goods. At this time, a thorough cleaning of the filling machine is required.

When cleaning the filling machine, it is important not to use water but to use a cleaning agent because the filler may encounter acid and alkali corrosion during the filling process, and the filling mouth is prone to rust. Cleaning agents can effectively remove rust.

The soda Filling Machinery operates under a complex yet efficient mechanism to ensure the precise filling of beverages while maintaining their signature carbonation. This process involves several stages, from bottle sterilization to capping, each contributing to delivering a high-quality, soda.

Bottle Washing: The journey of a beverage bottle within this machinery starts with rinsing. The bottles are thoroughly cleaned using an automatic bottle washer to eliminate any potential contaminants. This phase is crucial in maintaining the quality and safety of the final product.

Filling Station: Post-cleaning, the bottles move to the filling station, the heart of the soda Filling Machinery. Here, they are filled with the soda under carefully controlled conditions to preserve the drink’s carbonation. This step operates on the principle that carbon dioxide, the gas responsible for the ‘fizz’ in carbonated drinks, dissolves better in water when under high pressure. Thus, to prevent the loss of carbonation, the filling process is conducted under pressure.

Precision Filling: The machinery is designed to fill each bottle to an exact, pre-determined level, ensuring consistency in both the volume and quality of the product. This precision is made possible using advanced sensors that continually monitor the liquid level in each bottle. Once the desired level is reached, these sensors signal the machinery to halt the flow of the beverage into that particular bottle.

Capping: Immediately after filling, the bottles are sealed to prevent any escape of carbon dioxide, thereby preserving the carbonation of the beverage. A capping machine applies a cap or lid to each bottle, securing it tightly. This process is crucial as it maintains the internal pressure of the bottle, ensuring the beverage remains fizzy until it reaches the consumer.

Despite the intricate process, the underlying principle is simple: maintaining the right conditions throughout to preserve the carbonation, delivering a consistently high-quality, fizzy beverage.

Sparkling beverage filling machinery consists of several key structural components, each playing a crucial role in the overall operation of the machine. Here are the main components:

The main design goal of this filler valve is to effectively minimize severe foam and leakage during filling by slowing down the flow rate.

It achieves this slowed flow rate through 2 mechanisms:

Firstly, the flow dividing assembly diverts some of the beverage into a channel, reducing the flow volume and speed in the outlet pipe. This significantly slows down the flow speed as the beverage enters the bottle.

Secondly, the guiding portion has a helical groove that matches the inner wall of the bottle mouth. The beverage slowly spirals into the bottle along the groove.

By dividing and guiding the flow in this way, the filler valve is able to significantly slow down the speed at which the beverage enters the bottle.

The slowed flow rate effectively minimizes foam and leakage during filling, improving the filling quality and efficiency.

In summary, the filler valve achieves its goal of minimizing foam by slowing down the flow rate. The flow dividing assembly and guiding portion work together to achieve this slowed flow rate. Slowing the flow rate is key to minimizing foam.
