LINEAR RINSING-FILLING-SEALING MONOBLOCKS - MLE CAN

$0.00

The new inline monoblocks of the MLE CAN series are the result of an ambitious project that has the objective of satisfying the increasingly frequent requests for professional beverage canning machines at a low and medium production level.

Ideal for micro and mini breweries that require high quality can packaging. They are also suitable for other carbonated and natural drinks of any kind.

From now on, high-quality craft beers in cans are also possible.

The new linear monoblocks of the series MLE CAN are the result of an ambitious project that has the objective of satisfying the increasingly frequent requests for professional canning machines at a low and medium production level.

They are equipped with systems that guarantee the highest quality in rinsing, filling and sealing of aluminum beverage cans. All the rinsing, blowing cycles and the different volumetric filling phases can be adjusted from the control panel. The workstations use inert gas at each station, which greatly reduces the oxidation of the beer. Disinfection is easy and safe: all circuits are easily accessible and are designed to avoid contaminating stagnations.

The MLE CAN linear monoblock is also ideal for filling soft drinks, sodas, sparkling wines or any still beverage in cans.

An infeed screw introduces cans into the monoblock and moves under each station with perfect timing.
1- Rinser: The cans are grasped from the upper outer edge by a clamp and are turned upside down through a chain system with a stepper motor. The nozzle enters the can 15 mm. The two injection circuits (water and air) are completely separated. Injection durations are adjustable through the control panel and operation occurs only when the can is present. The trickle of the liquid is collected in a closed circuit without wetting the machine. Air injection substantially reduces water remainings in the can.
2- Filler: The cans are moved to the filler where the pneumatic pedestals are located that lift them towards the filling valves. The following operations are performed in sequence:
• Presence detetection of cans (if absent, the filling cycle does not start);
• Gas injection, which replaces the air in the can with inert gas to reduce the presence of oxygen;
• Filling
• Leveling (if necessary);
• Degassing.
A transducer constantly checks the internal pressure of the can (the valve does not perform the filling operation if the can does not reach the pressure of the tank). The fill level is centralized and can be adjusted manually. The valve can fill still and carbonated liquids with pressure between 0 and 4 bar. The fill level is accurate even without the leveling operation. The valve closes completely and this improves degassing even with particularly difficult products. Operating pressures are set from the control panel. The filling valve is under patent protection.

3- Cover dispenser: four covers are released singularly from the magazine and are dropped onto a side scroller, which moves on top of the cans, then the injection of inert gas and the water jet are carried out to froth the beer. The gripping devices hold the covers and position them over the cans with slight pressure when the sideshifter is removed. The gas injection and the water jet circuits are completely separated. Those operations are performed only when the can is present and the duration is set on the control panel and handled by PLC. The injection of neutral gas and the jet of water for frothing the beer substantially reduce the amount of oxygen in the space between liquid and lid.
4- Sealer: the intermitent star moves the can on the elevator, which lifts it and brings it closer to the rotating mandrel. As the can rotates, the two rollers seal it. All operations are controlled by mechanical cams.
5- Weight control: After sealing, the can is moved to a load cell to check the weight: if it is lower or higher than the preset values, the can is ejected through the ejector included in the supply.
6- Washing tunnel: Outside the monoblock there is a washing tunnel for cans.

In the same structure, there are four can cover storage columns and chargers to supply the distributor. Covers can be easily inserted  in the four magazings while the monoblock is working. The change of chargers is made by means of a quick coupling. The monoblock can be provided with a CIP cleaning and disinfection system. Manual dummy cans are provided for the rinse unit, filler, and gas injection / water jet system.
