On the production line, raw materials will go through a series of processing steps, such as mixing, stirring, filtering, etc., to ensure the taste and quality of the beverage. Next, the processed beverage is fed into the filling machine. Aluminum cans need to be cleaned again before beverage filling.
After the beverage filling is cleaned and dried, the beverage and bubbles can be filled through the filling machine... However, among all canned beverages, carbonated beverages and beer are the most enjoyable, completely. This is enough carbonated gas! If you are at the processing site, it is best to taste it directly, because freshly made bubbles are the most abundant and delicious!
The function of the filling machine is to accurately inject beverages into cans. During the filling process, the machine will accurately control the filling volume of each can to ensure that the weight and volume of each canned beverage meet the standards. At the same time, the speed and efficiency of the filling machine also directly affect the output of the entire production line.
Beverage filling plants have a very high level of automation, usually requiring only one worker, and his job is just to put the bottle caps on the conveyor pipe...
The machine will then automatically place the caps on the bottle one by one.
After filling is completed, the can will enter the next step - sealing. Sealing is done by using a special sealing machine to curl the can body and lid to each other, and then press them tightly to form a tightly overlapping crimp. The crimp formed in this way is also called "double crimp".
The sealing machine seals the opening of the can tightly through heat sealing or mechanical sealing to ensure that the beverage does not leak during transportation and storage. The quality of sealing directly affects the sealing performance and shelf life of cans. This seems to be just a tightening action, but if we pick up a can of Coke, please pay attention to the connection between the mouth of the can and the lid. Will you find that the thickness of the edge is different from the other parts of the aluminum can? This is actually a "rolling operation", a packaging method to prevent air from entering or exiting.
In addition, from the aluminum can lids in the picture, we can find that the pull tabs on the can lids are now basically SOT lever type. The RPT type is relatively rare, and the pull tabs of RPT can lids are easy to scratch. Being thrown away casually. Because modern product design often needs to find a balance between safety, environmental protection and convenience. The SOT lever design shows its superiority in many aspects.
After completing the sealing, the can will enter the cooling stage. Cooling cans through cold air or cold water can quickly cool down the beverage and achieve an ideal storage state. At the same time, the cooling process also helps to improve the hardness and stability of the can, making it easier to store and transport.
Next comes the labeling and packing process. The labeling machine puts labels with product information on cans for consumers to identify and purchase. The cartoning machine packs the labeled cans into cartons in a certain arrangement for easy transportation and storage. During this process, quality inspections are also required on the boxed products to ensure that each product shipped out meets the standards.
The last step is factory inspection. Factory inspection is the final check on the entire production process. Through sampling testing and other methods, it is ensured that the canned beverages leaving the factory comply with national standards and laws and regulations. Only products that pass strict inspection can be sent to the market for sale.
