Keg Systems

Our kegging systems’ portfolio, provided by our company Comac, features automatic and semi-automatic keg lines for the packaging of beverages (focusing on beer) in kegs of any size.

This range includes small machines able to handle 15 kegs per hour and complete lines with filling capacity featuring 1,200 kegs per hour.
Our kegging systems are divided into three categories: semiautomatic systems for production up to 40 kegs/hour, automatic systems for productions ranging from 40 to 250 kegs/hour and automatic systems for production over 250 kegs/hour.
The series are completed with ancillary machines such as keg washers, capping stations, keg turners and lowers.

BERGAMO - LINEAR HIGH-SPEED KEG PRE-WASHERS, WASHERS AND FILLERS

Speed from 250 KPH and up. High-speed modular keg systems.
BERGAMO - LINEAR HIGH-SPEED KEG PRE-WASHERS, WASHERS AND FILLERS

Fully automatic modular system of pre-washing, washing and filling for kegs, designed for high-speed and high-efficiency production lines.

OVERVIEW

 

The keg system consists of three modules: a pre-washing module, a washing module and a keg filler. Each module is made of AISI 304 stainless steel and equipped with six treatment heads.

The pre-washing and washing heads are in stainless steel AISI 304L or AISI 316L (in case of use of acid solution), with internal roughness <0.6 μ, equipped with EPDM seals, PTFE valve obturators and magnetic sensors, to control the opening of the fitting.

The filling heads are made of stainless steel AISI 316L, with internal roughness <0.6 μ, equipped with EPDM seals, PTFE valve obturators and magnetic sensors, to control the opening of the fitting.

The filling of the kegs is controlled by a flowmeter.

The kegs are introduced into the machine via a robotic system, which transfers them directly into the various treatment heads, equipped with devices for the control of the working cycles.

The electrical panel installed in the machine is made of stainless steel (IP54) and provided with PLC; the pushbutton control panel too is made of stainless steel (IP54).

The modules are supplied complete with automatic sanitization systems that do not require the manual installation of false kegs.

BERGAMO - LINEAR HIGH-SPEED KEG PRE-WASHERS, WASHERS AND FILLERS

PRODUCTS: beer, cider, sparkling and still wine, carbonated soft drinks

FORMATS: kegs

BENEFITS:

 

  • Extremely high efficiency rates and High hygiene degree
  • Optimization of the cycle times due to a fast loading system and a working cycle which do not require the keg to be moved from one head to another inside the machine
  • Reduced fitting gasket and spring wearing, as pre-washing, washing and filling processes are distributed on three heads, with significant reduction of keg maintenance cost
  • The limited number of fitting opening strokes grants a reduced wear and tear of the guide sleeves and head components and, therefore, it leads to reduced downtimes, maintenance times and costs
  • flexibility, thanks to the independence of each pre-washing, washing and filling head from the others. A damaged or faulty head can be excluded from operation while production continues on the others
  • Equipped with components of well-known brands, easy to find on local markets

KEG CAPPERS AND DECAPPERS

Speed range from 60 to 1.000 KPH and higher. Machines designed to deposit or remove caps on or off the keg neck.
KEG CAPPERS AND DECAPPERS

Cappers and decappers are usually installed in automatic keg lines, in which the intervention of operators to perform manual operations is extremely reduced.

OVERVIEW

 

On the empty keg side of the line, a decapper can be installed to remove any possible cap still on the neck of the kegs; on the full keg side of the line, cappers deposit a cap on each keg valve, in order to protect it from dirt and dust.

Upstream of the capping machine, the installation of a keg fitting disinfection system is recommended, so as to prevent any possible formation of molds underneath the cap, even under poor storage conditions. After the capping machine, a cap presence control device can be provided, to make sure all kegs have been properly capped.

KEG INSPECTION DEVICES

Speed range from 60 to 1.000 KPH. Devices designed to detect the keg position on the conveyors, possible presence of a cap or collar on the keg neck.
KEG INSPECTION DEVICES

In completely automated keg lines, where no intervention or visual control by the operator is required, the inspection devices make sure the empty kegs are in the correct position (upside-down or upright) and have no cap on the keg neck. The technology used by these devices varies depending on the line configuration and the position of the devices themselves (control from the top or bottom).

Keg external washers

Speed range: from 30 to 1.000 KPH and higher. Machines designed to wash the external surfaces of kegs in keg lines.
Keg external washers

Comac range of external washers includes machines consisting of a various number of sections, depending on both line speed and type of cleaning to be performed.

OVERVIEW

 

Our smallest machine has a useful length of 2 meters, one section and one lane, and performs a simple cleaning with water (hot or recovered). The next model, which can be 3 or 4 meters long, is designed to perform a first pre-washing with recovered water, a washing with caustic solution to remove the ink-jet code, and a final rinse with clean water.

These basic configurations can be increased with further sections, to extend the pre-washing in order to drain the water sprayed by the first showers and recover the next, extend the caustic washing, add a high pressure cleaning section if labels must be removed from kegs, etc.

In case of high capacity keg lines, the external washer can even be designed with two lanes.

KEG WEIGHERS

Speed range from 30 to 1.000 KPH. Static and dynamic weighers to check the empty and full keg weight.
KEG WEIGHERS

Static weighers are installed aboard the keg washers/fillers – walking beam type – to check the weight of kegs after filling and, possibly, the tare weight also, in order to compare the empty and full keg weights and be able to reject kegs that haven’t been filled correctly, or contain an incorrect volume of beer.

OVERVIEW

 

In medium-to-high speed keg lines, where several keg washers/fillers are installed, static weighers are usually replaced by dynamic weighers, which check the weight of kegs without stopping them.

Static weighers are controlled by the PLC of the keg washer/filler, while dynamic weighers are provided with their own PLC and HMI, which also communicate with the PLC of the keg line.

KEG TURNERS

Speed range: from 30 to 1.000 KPH. Machines designed to turn kegs in upside-down or upright position.
KEG TURNERS

All turners are provided with stainless steel and Plexiglas protection guards.

OVERVIEW

 

Comac range of keg turners includes:

  • selective turners, which only turn kegs detected to be in a defined position and work as simple conveyors when kegs do not need to be turned;
  • simple cross and double cross keg turners, for empty or full kegs;
  • turner/lowerers which, besides turning the kegs, also take them to a lower level with respect to the kegging hall floor.

Collar application and extraction systems

Speed range from 60 to 1.000 KPH and higher. Machines designed to deposit or remove a collar label on or off the keg neck.
Collar application and extraction systems

Collar labels are very popular among breweries and their use is spreading quickly. Collar application and extraction systems can be provided with automatic keg lines, in which the intervention of operators to perform manual operations is extremely reduced.

OVERVIEW

 

On the empty keg side of the line, a system for the removal of any collar still on the neck of the kegs can be installed, in order to prevent these labels to reach the external keg washer; a collar presence detection device communicates to the collar extraction system whenever a label needs to be removed.

On the full keg side of the line, a collar applicator can be used to deposit the collar label around each keg valve.
