Can filling and packaging line:

Aluminum cans are classified by material into aluminum cans, PET cans, and tinplate cans. In terms of shape, they are categorized as slim, sleek, standard, and stubby. The aluminum cans you choose must have the same diameter, which means that all the lids must be of the same size. Otherwise, they cannot be used interchangeably on the filling machine. Are your empty cans already painted or do they require sleeve shrink labeling? If they are blank, you will need a sleeve labeling machine to put the labels on the cans and then conduct heat shrinkage.

If your cans are made of PET, you may need the following two machines.

Automatic PET Can Making Machine(Bottle blow molding machine and bottle neck cutting machine for making PET can)

There are two methods for producing PET cans by using the Automatic PET Can Making Machine (consisting of a bottle blow molding machine and a bottle neck cutting machine for making PET cans).

Direct blowing method with PET can blow molding machine: For this method, you need to have can pre – forms. However, the disadvantage of this method is that the blow molding machine has a single function and can only be used to produce cans, not bottles.
Two – step production method with PET bottle blow molding machine and can cutting machine: The PET bottle blow molding machine first blows the pre – forms into bottles, and then the upper part of the bottles is cut off by the cutting machine to obtain PET cans. The mold of the blow molding machine requires special design. As shown in the figure above. The blow molding machine can be of an automatic type and can be connected to the cutting machine through air delivery. Such a blow molding machine can also produce various bottles by changing the mold.

Treatment of Water:​

Categories: Water treatment systems involve RO (Reverse Osmosis) treatment facilities, UF (Ultrafiltration) water treatment facilities, DRO (Dual Reverse Osmosis) facilities, RO combined with EDI (Electrodialysis, EDI) devices, RO combined with electrolysis for producing weakly alkaline water devices, and seawater desalination treatment facilities.​For bottled water filling lines, Reverse Osmosis water treatment facilities are commonly equipped.​
The Working Principle of Reverse Osmosis Water Treatment: High pressure is applied by the machine to make water pass through a semi-permeable membrane, eliminating dissolved salts, organic substances, bacteria, and viruses in the water, so as to acquire high-purity water.​
Constituent Parts: Raw water reservoir, quartz sand filter unit, activated carbon filter unit, water softening filter unit, precision filter unit, reverse osmosis membrane, ultraviolet disinfector, ozone generator, ozone mixing tower, pure water reservoir.​
Production Capacity: Our machines have production capacities of 250 liters per hour, 500 liters per hour (lph), 1000 liters per hour (lph), 2000 liters per hour, 3000 liters per hour, 5000 liters per hour, 8000 liters per hour, 10 tons per hour, 20 tons per hour, 30 tons per hour, 50 tons per hour, 100 tons per hour.​

Please check the video of Empty cans depalletizer unloading unstacking machine: https://youtu.be/Nnwuifh1Jpo

Empty can depalletizer:

I. Working Principle
Pallet Positioning:
The stacked empty can pallet (usually carried by plastic pallets or cardboard) is automatically positioned to the unloading station through the conveyor line.
Layered Grabbing:
The vacuum suction cup group or mechanical gripper absorbs/grabs the entire layer of cans from the top of the pallet layer by layer (usually 20-40 cans per layer, depending on the pallet type design).
Single Can Separation:
The layered cans are dispersed into a single row through a vibrating can separator or a centrifugal can separator and enter the conveyor belt.
Abnormal Detection:
The photoelectric sensor detects the inversion, deformation or foreign matter of the can body and automatically removes unqualified cans.
II. Core Features
High Speed ​​and Efficiency:
The unloading speed can reach 1,500-3,000 cans/minute (depending on the can diameter and the stack height), supporting continuous production.
Intelligent Adaptation:
It is compatible with different can diameters (such as 200ml-500ml), can heights and pallet specifications (adjusted by touch screen parameters).
Low-loss design:
The vacuum suction cup is made of food-grade silicone to avoid scratching the can body; the buffer device reduces collision deformation.
Modular structure:
Quick changeover design, changing the can type only requires changing the gripper/suction cup module, and the switching time is less than 15 minutes.
Energy saving and environmental protection:
Servo motor drive, energy consumption is 30% lower than that of traditional pneumatic systems.
III. Application scenarios
beverage production line: empty can loading before filling cans such as cola, beer, and energy drinks.
Canning factory: empty cans are re-stacking or boxing after quality inspection.

Please check the video of 2 in 1 can Filling-Capping machine: https://youtu.be/KB7exND95cg

2 in 1 can Filling-Capping machine:

There is a can – washing tunnel between the depalletizer and the filling machine. After passing through the flipping mold, the mouth of the aluminum can faces downward. Through the can – washing tunnel, the inside of the aluminum can is flushed with water or air, and then it reaches the filling machine.

I. Core Classification and Principle Comparison
II. Carbonated beverage filling machine (Taking Carbonated Drinks/Beer as Examples)

Working Principle
Pre – charge of CO₂: After the empty can enters the filling valve, CO₂ is first injected to expel the air and establish a balanced pressure with the liquid storage tank (usually 0.8 – 1.2 bar).
Isobaric Filling: The liquid flows into the can under a state of no pressure difference, and the liquid level is precisely controlled by a mechanical float or a flow meter.
Pressure Relief and Gas Return: Residual gas in the can is released before the end of filling to prevent splashing when the can is opened.
High – speed Can Sealing: The can – sealing machine completes the crimping and sealing instantly (≤0.5 seconds per can) to ensure airtightness.
III. Non – carbonated Beverage Filling Machine (Taking Juice/Cooling Tea as Examples)
Working Principle
Sterilization Pretreatment: The beverage sterilized by UHT is cooled to 25 – 30℃ and enters the aseptic filling system.
Negative – pressure Filling: Evacuate the air in the can (-0.8 bar) to reduce the risk of oxidation.
Hot Filling (Optional): Directly fill at a high temperature (85 – 93℃) and use the residual heat to sterilize the can body.
Can Sealing + Coding: After normal – temperature can sealing, the production date is laser – printed.

Can hot water spraying warming tunnel:

Can Warming Tunnel is also called tunnel sterilizer. Because cans filled with 4-degree beverages encounter normal temperature atmosphere, many water droplets will appear on the bottle body, which is not conducive to labeling and coding. At this time, a bottle warming machine is needed to slowly heat up the cans, blow dry them, and then label and code them. The bottle warming machine heats the cans to room temperature 30-35℃. The bottle warming machine is a tunnel spraying equipment that heats the bottle body by circulating hot water heat exchange. The bottle warming machine is mainly composed of a frame, a conveyor chain plate, a traditional system, a water storage tank, a circulating pump, a spraying device, a heating device and a pipeline.
Bottle warmers can also be divided into: bottle warmers without sterilization sections (direct cooling, standard) and bottle warmers with sterilization sections (heating first and then cooling).
The bottle warmer with sterilization section adopts four sections: preheating-sterilization-precooling-cooling and sprays the items from top to bottom for sterilization. The sterilization temperature of different products is different. The temperature of the equipment can be set arbitrarily, automatically controlled, maintained at a constant temperature, and automatically recorded.
If it is a carbonated beverage, it is generally not equipped with a sterilization section.
If it is beer, it can generally be equipped with a sterilization section. The sterilization temperature is about 65-75 degrees, and the normal sterilization section holding time is 10-15 minutes.

Please check the video of automatic sleeve shrink labeling machine: https://youtu.be/OF9g_sU5Yww

Sleeve labeling machine:

If your cans are not printed, then you need a sleeve labeling machine. If you buy printed cans in China, the minimum order quantity is 500,000.
The sleeve labeling machine consists of a sleeve labeling machine, a steam shrinking furnace, and a steam generator.
The sleeve labeling machine cuts the label and puts it on the can. The steam shrinking furnace heats the hot water to generate steam and disperses the steam into the shrinking furnace through a pipe. When the label encounters the high-temperature steam, it will stick tightly to the can. After shrinking, there will be a lot of water droplets on the label, so it is best to add a blow dryer behind the sleeve labeling machine.
The sleeve labeling machine can be used for bottles of various sizes, but you need to pay extra for the change parts.
We can also provide a double-head sleeve labeling machine, with 2 sleeve labeling stations in one machine, one for the bottle body label and one for the bottle cap label.
The steam produced by the steam shrinking oven will make the inside of the factory a little humid, so you need to connect a steam exhaust pipe to the outside. If you don’t want the steam shrinking method, we can also provide electric heating shrinking ovens, but electric heating shrinking ovens do not heat as evenly as steam, so some places may shrink well, and some places may not shrink so perfectly. We can customize 2 conveyor lines, one with fast speed and one with slow speed, so that the cans or bottles can rotate by themselves, so that the shrinking effect will be very good. But in general, we recommend that you choose the steam shrinking method.

Can packaging machine:

The packaging of cans mainly includes Half tray+film packing, transparent film packing, colourful film packing, and carton packing. Which one do you choose? Each form corresponds to a different machine.
If your packaging contains a half tray, then half tray has three forms
1, The tray is already formed
2, The tray a sheet shape and requires machine gluing folding film packing
3, The tray a sheet shape and no gluing but requires machine folding and Film packing
What form is your half tray in? Each form corresponds to a different machine.
The tray is already formed machine is semi-automatic, the price is 2500-5000 USD, the half tray with glue+film packing machine price is 60000-70000 USD, the transparent film packing machine price is 2500-25000 USD, the colourful film packing machine price is 30000-50000 USD, the carton packing machine price is 20000-50000 USD

Palletizer Equipment, Stacking Pallet Provider, and Pallet Stretch Film Wrapping Machine

Palletizer Equipment

The palletizer equipment picks up the film – covered bottles one by one and arranges them on pallets. The pallets are automatically supplied by the stacking pallet provider. Once a stack of bottles is successfully palletized, it is conveyed to the rotating platform of the pallet stretch film wrapping machine through rollers. When the photoelectric sensor determines that the pallet has reached the correct position, the rotating platform starts to spin, and the stretch film is wrapped around the stacked bottles. This makes the stack of bottles more secure during transportation, avoiding bottle falls and facilitating forklift transportation to supermarkets.
There are different kinds of palletizer equipment. Some use air – pressure suction to pick up bottles, and some use mechanical arms for grabbing. In terms of structure, there are column – type and gantry – type palletizer equipment. The column – type is fit for small – sized production lines, while the gantry – type, with better stability and higher load – bearing capacity, is suitable for large – sized production lines.

Stacking Pallet Provider

The stacking pallet provider can automatically distribute pallets. The pallets are the trays at the bottom of the stack that hold up the bottles. If the customer also wants separator boards, another piece of machinery is needed to deal with this. Placing the bottom pallets and separator boards can be done by hand, but automated equipment can increase efficiency and lower labor costs.

Pallet Stretch Film Wrapping Machine

Stretch film wrapping machines are divided into self – rotating pallet stretch film wrapping machines and non – rotating boom – type stretch film wrapping machines. If the self – rotation of the pallet is steady, an automatic stretch film wrapping machine can be chosen. If the pallet is very high and self – rotation could lead to items dropping, a non – rotating boom – type stretch film wrapping machines. If the self – rotation of the pallet is steady, an automatic stretch film wrapping machine can be chosen. If the pallet is very high and self – rotation could lead to items dropping, a non – rotating boom – type stretch film wrapping machine is required. The boom – type stretch film wrapping machine wraps the film around the pallet by rotating its boom, which is suitable for high – stack pallets or pallets with non – standard shapes.

Liquid nitrogen injection machine:

If the beverage you fill is not a carbonated beverage, you may need this machine, which is installed behind the filling machine and in front of the canning machine.
I. Working principle
Liquid nitrogen gasification expansion:
Liquid nitrogen (-196℃) is quickly gasified after being injected into the tank, and its volume expands by about 700 times, quickly discharging the residual oxygen (O₂) in the tank, forming a slightly negative pressure environment.
Oxygen replacement: Nitrogen (N₂) inert gas replaces oxygen to prevent the beverage from oxidizing and deteriorating (such as vitamin loss and flavor deterioration).
Pressurization and shaping: The gasified nitrogen increases the pressure in the tank (usually 0.2–0.5 bar), enhances the rigidity of the aluminum can/PET can, and prevents deformation or dents caused by pressure changes during transportation.
II. Equipment composition
Liquid nitrogen storage system: low-temperature storage tank (-196℃ insulation), liquid nitrogen delivery pipeline (vacuum insulation design).
Gasification and metering module: gasifier (electric heating or ambient heat exchange), high-precision flowmeter (control nitrogen injection amount ±0.1ml).
Nitrogen injection actuator: multi-channel nitrogen injection needle valve (adapt to different tank mouth sizes), servo drive system (synchronous filling line speed).
Detection and feedback system: oxygen content sensor (detect O₂ residual in the tank ≤0.5%), pressure sensor (closed-loop control tank pressure).
Control system: PLC+HMI interface, preset nitrogen injection amount (adjusted according to tank capacity), fault alarm (such as liquid nitrogen leakage).
III. Core function
Extend shelf life: oxygen content is reduced to <1%, inhibiting microbial growth and oxidation reaction, and extending the shelf life at room temperature by 30-50% (such as tea beverages from 6 months to 9 months).
Strengthen tank structure: the increase in internal pressure increases the compressive strength of aluminum cans by 2-3 times, and the dent rate during transportation is reduced by 90%.
Improve appearance: eliminate the dents caused by negative pressure in the tank, and the shelf display is more beautiful.
Environmentally friendly and efficient: extremely low liquid nitrogen consumption (0.1–0.3g per can), no chemical residue, and meets food-grade safety standards.
Wide adaptability: compatible with aluminum cans, PET cans, and tinplate cans, supporting high-speed production lines (up to 2,000 cans/minute).
IV. Workflow
Empty can delivery → precise liquid nitrogen injection → liquid nitrogen gasification/oxygen discharge → can mouth sealing → pressure detection → finished product output
