Materials

It is not just beverage ingredients that are sent to the factory, but also other materials such as bottles, cans, labels and packaging. Many factories outside the United States are motivated by economic considerations , all use reusable bottles, while Coca-Cola does not do this in the United States. When bottles and cans are sent to the factory, they are carefully inspected to ensure that they meet their strict standards. After passing the inspection Afterwards, they will be sent for cleaning and washing.

Cleaning and Rinsing

In order to ensure quality, each bottle must be strictly cleaned, disinfected, and rinsed before bottling. The process sounds simple, but the actual operation of a single bottling plant is very rigorous. Many bottling plants outside the United States use glass or plastic bottles that can be filled multiple times. In order to ensure the cleanliness of the bottles The degree meets their regulations. First, rinse with a cleaning nozzle to remove dirt. Then soak the bottle in a high-temperature deep cleaning detergent to further remove residue and disinfect it. After that, the bottle is transported to the "high-pressure rinser" ", do a more thorough high-pressure jet rinse. Finally, after the bottle passes visual inspection and/or electronic inspection, it must be rinsed with cold water jet. Since disposable glass bottles are mainly used in the United States, they are rarely used and can be used multiple times. bottling, so the cleaning process is faster. It takes 112.2 Hours to clean 100,000 bottles

Mixing and Stirring

1. Water & Sugar

Mixing is simply Purified water and syrup are mixed to make a simple syrup. Some countries determine the correct proportion based on one-time ingredients, while many countries in North America and Europe use continuous mixing systems.

2. Secret Recipe

The secret recipe of Coca-Cola is still a secret! Yes, to the countless consumers in nearly 200 countries who drink our refreshing beverage every day, the secret recipe is still a mystery. Even Coca-Cola The company can't tell us this secret, but we can rest assured that Coca-Cola will make "life full of joy."

3. Water and syrup

As the syrup approaches its final state, Coca-Cola The production line mixes it with purified water to make non-carbonated drinks. However, water and syrup still need to be mixed in a certain ratio. This needs to be done with a beverage proportioning instrument, which can accurately measure each time. The ratio is then sent to the carbonation device.

4. Carbon dioxide

Adding CO2 or carbon dioxide gas is the last step to carbonate the beverage alcohol. Carbon dioxide not only makes Our drinks add boiling gas and give everyone the unique and familiar taste they expect. Mixer (6000L/h)

Syrup (flavorless or sub-sugar), co, water (According to a certain proportion) Later experience:

Sealing conveyor pipe

Filling machine (300 cans/min)

Can sealing machine

Packaging room (500 bottles/unit)

Bottling

When all the raw materials are mixed and stirred, and After the bottles are cleaned and disinfected, workers can start bottling. The bottling process is very complex and every step needs to be accurate. First, the bottles are accurately transferred to the filling machine to ensure that the filling process is synchronized. Completed. Before the bottle is transferred to the filling machine, the glass bottle is tightly clamped by a flexible flat clamp, or the glass bottle is accurately positioned at the filling place by a centering device. Before filling, the bottle The inside needs to be pressurized first, so that the beverage can flow into the bottle smoothly when it is poured, and the production of foam can be avoided and reduced as much as possible.

Capping

After bottling the beverage, it needs to be capped. We need different caps for different bottles - glass bottles generally use crown caps, while plastic bottles mainly use plastic screw caps. Each cap type must go through different inspection points to ensure that the cap has no scratches and Accurately press on the bottle mouth. (The picture shows the capping machine) (Canning capping machine)

Product quality and freshness are crucial, and the Coca-Cola production line uses "no Cover (no-closure)" tester, use "go-no-go-guage" (go-no-go-guage) and "torque tester" (torgu) after installing the cover

e meter). The "capless" tester is used to test whether screw caps and crown caps are attached to the bottle mouth. If the tester does not find the bottle cap, the testing process will stop. The pass-and-stop gauge is responsible for detecting the folding edge of the gland. The torque tester is responsible for ensuring that the screw cap is intact and tightened. If the cap is not in place, the carbon dioxide in the beverage will leak, resulting in insufficient gas content, or other unfavorable conditions, and the product must be picked out and scrapped.

After completing the bottling and capping process, labeling can begin. The label is passed through the roller, and then cut and pasted onto the bottle. If the label is customized for a bottle with special commemorative significance, For example, in football matches, a product license must be obtained before it can be used. Sometimes, bottles with special commemorative significance can only be used in specific locations. For example, bottles specially made for a national football championship are only suitable for use in local championships. Team.

Coding

Bottles can now be coded. Every bottle of beverage produced by Coca-Cola needs to be coded in order to record the production information of the beverage, such as: bottling of the product Or stamping date. Some numbers appear in the form of dates, while others are more complex. These codes use a combination of letters and numbers to indicate the day, month, shift and factory of beverage production. If you can’t find it on the packaging When it comes to coding, it may be because some bottling plants use invisible ink, which can only be seen through special instruments. Coding products can ensure that consumers can buy our highest quality products. (Coding) Inspection< /p>

The production process of Coca-Cola products is very rigorous and needs to be carried out multiple times. For glass bottles that can be used multiple times, they need to be inspected as soon as they enter the factory. They are also inspected multiple times after cleaning and bottling. The inspector should pay attention to whether the appearance of the bottle is damaged and verify that the filling quantity is equal. Although the machine cannot completely replace manual inspection, the Coca-Cola production line also uses inspection instruments for quality inspection. When inspecting empty bottles, the inspector will emit a beam of strong Light shines through the bottom of the bottle onto the opposite light cluster. If the light wave changes, it means that the bottle can no longer be used. After bottling, some factories use precision instruments to detect whether the beverage capacity in the bottle is accurate. Each bottling factory also Samples of bottled products need to be randomly inspected in the laboratory to ensure that the quality is up to standard. (The picture shows manual inspection) (The picture shows the bottle inspection machine) Electronic bottle inspection machine (bottle)

First rinse with NaOH The inside and outside of the bottle are rinsed three times with bottle washing liquid, high-temperature sterilized, and then the bottle mouth inspection machine is specially used to detect whether there is a gap in the bottle mouth

Then there is the process of bottle filling machine/capping machine (the working efficiency is 300 bottles/ points)

Packaging

Once the beverage is bottled and passes quality inspection, it must be packaged to facilitate transportation to various places. Generally speaking, the entire process of packaging involves everything from the initial bottling to and can design, to label design, to cartons and containers, and even plastic ropes and other aspects. Since consumer needs and tastes vary widely, packaging will also vary depending on the location where the beverage is delivered. All the same.
