Application of sealing machine in beer production line

The packaging process for canned beer is simpler and easier to control than for bottled and cask beer. The main equipment of the automated canning production line includes depalletizer, can sealer, sterilizer, and box sealer. Its filling speed can reach 1,000 cans per minute, which is comparable to the canning equipment of Tingzi Factory.

The beer canning process is as follows: the can sealer unloads the stacked empty cans from the plastic tray, pushes them to the plastic chain plate, enters the cleaning machine, rinses them with 80℃ hot water and drains them to achieve a sterile state. Then carbon dioxide isobaric filling is used to replace the air in the tank with carbon dioxide. After filling, carbon dioxide is sprayed into the tank mouth and quickly capped. The liquid level is detected by an automatic meter and then pasteurized (spray sterilization).

The filled tank is dried by an air dryer, and then the inkjet printer marks the production date on the bottom of the tank. Different can sealing machines are selected according to the packaging form: single-piece die-cut cardboard adopts covered can sealing, pressing the can body onto one side of the cardboard, the mechanical rod alternately lifts the other large side and both sides, and hot melt adhesive quickly bonds the manufacturer's seams and folds. Covered can sealing is widely used in domestic breweries. The suction cup type cartoning machine draws the large surface into a groove through the suction cup, and the mechanical rod pushes the ear piece inward to bond it. This method of packing is extremely efficient and widely used abroad. The wrapping cartoning machine can also package thermoplastic film cans with paper holders. Such fashion cartoning machines need to be equipped with a PE film slitting, wrapping system and heat shrink oven. If there is a printed pattern on the surface of the PE film, it needs to be equipped with a photoelectric eye device. After being sealed in automatic boxes, OPP sealing tape is usually no longer used for listening boxes. The standard 355ml can size is 24 cans/carton, and 18 cans and 12 cans are also available to suit consumers' whole-carton purchasing habits.

Modern beer technology widely uses computer recognition systems and digital display instruments to assist mechanized filling operations, ensuring that the quality of beer is not affected during the filling process. The tank sealer can automatically detect tank manufacturing defects: oil, liquid leakage, deformation, foreign matter and odor, and remove unqualified containers from the production line.
