KHS can filler processes a broad spectrum of beverages & formats
Light, compact, and convenient, the beverage can is experiencing something of a renaissance. More and more are existence sold practically everywhere globally, with a rising in market shares to friction match. In Germany, for example, this number rose from 2.85 billion in 2022 to over iii.9 billion in 2019. The forecast is for farther growth. Equally 1 of the world's leading manufacturers of filling and packaging equipment, KHS has decades of expertise in this segment. The turnkey supplier has now expanded its tried-and-tested technology for both the loftier-and medium-capacity ranges.
Consumers take appreciated the advantages of the drinkable tin can for decades, nevertheless just recently, the market share for cans has again shown a marked increment. According to KHS, there are numerous reasons for this. On the one hand, more and more free energy drinks are being sold in cans; on the other, the craft movement is pushing this evolution past increasingly filling soft drinks, hard seltzer, beer, and cider into this format.
KHS said it can also look back on a long tradition in this segment. The Dortmund technology company entered the American tin marketplace over 50 years ago. Since then, information technology has asserted itself with numerous new technologies and positioned itself every bit one of the world's leading providers of canning equipment. The turnkey supplier is again building on its decades of expertise to continuously further amend its tried-and-tested systems. A whole host of contempo updates is designed to brand the tin can fillers for the high- and medium-capacity ranges even more flexible and hygienic.
In 2014 the systems provider presented the first tin can filler in a new generation in the form of its Innofill Can DVD that tin process up to 135,000 cans an 60 minutes. In 2022 KHS began specifically targeting SME canners with its compact Innofill Can C can filler that at the time was able to make full a maximum of 28,000 cans an 60 minutes.
Gentle can guiding and filling
Both machines merits to offer many advantages and fix standards – in hygiene, for example, due to the reduced cleaning effort, the extremely aseptic design and elimination of water lubrication in the filler carousel expanse prevent the open cans from beingness soiled. This allows cleaning intervals for outside cleaning to be lengthened.
The essential upgrade concerning hygiene on the Innofill Tin DVD, however, is the pneumatic lowering device for the centering bells. Unlike previous models, these are no longer moved mechanically by rollers and cams. Instead, the proven pneumatic lifting and lowering motion establish on the smaller Innofill Can C filler is at present also being used here, explains Manfred Härtel, filling production manager at KHS. "With this arrangement we reduce the number of fittings on the valve. On a filler, the rollers specially are subject to heavy wear. This ways that a certain amount of abrasion can be caused above the open cans. With this now no longer an issue in the future, nosotros've managed to once more considerably increase what was already a very high level of hygiene."
The lifting and lowering of the bells are intelligently controlled, said KHS. As cans are condign ever thinner as weight and materials are saved, information technology's specially essential to guide and fill up the containers as gently equally possible. Pneumatic actuation allows the contact pressure to exist adapted to suit dissimilar qualities of the fabric. The once new technology has long outgrown its pioneer status and since proved itself on the market many times over; the recent technological upgrades have improved it even further.
"Nosotros satisfy high hygiene requirements, especially those fabricated by sensitive beverages such equally not-alcoholic beer, mixed beer beverages and flavored ciders," Härtel continues. KHS tin fillers display a loftier standard of hygiene inside the motorcar and exterior information technology – an attribute that'due south becoming increasingly important given the trend towards beers and mixed beverages with less or no alcohol. "Our filling valves are famous for their aseptic properties, compact design and uncomplicated handling and maintenance," states Härtel. This is particularly benign to bottlers with a broad assortment of products, this requiring maximum flexibility of the technical equipment on the production line.
Made possible by Teflon
It'due south worth looking at the details, both of the Innofill Tin DVD and the Innofill Can C. I essential prerequisite is needed to accomplish the required flexibility in choosing the right sealing material for the joint expansion seal. "Nosotros proceed to rely on Teflon here," says Härtel. "This material can be excellently cleaned, gives our valve seals a much longer service life and doubles the change intervals with the added bonus of much shorter changeover times."
Looking at the range of materials on offer, however, what's most important is that PTFE absorbs practically no flavoring substances – dissimilar standard seals made of elastomers such as EPDM that soak upward liquid like a sponge during production. When at that place's a drop in concentration with the next product in the filling sequence, the EPDM rereleases these flavorings. To prevent this unwanted result, production has to exist scheduled by season. "The calendar week thus starts off with a mineral water, for instance, and ends with the filling of a product with an intensive sense of taste, such as an energy potable. With our filling valves the transfer of flavor is cutting down to an absolute minimum, giving customers more liberty when planning," Härtel smiles.
Warm filling
According to KHS, with the ii revamped KHS tin fillers beverages can as well be filled when warm. This process becomes more significant, specially regarding the processing stages further down the line, every bit information technology eliminates condensation formation. This more or less rules out the risk of cartons, trays, and cans in half dozen-packs growing soggy, forming mold, or existence contaminated by microbes. Beer is filled at a temperature of up to twenty°C and carbonated soft drinks at 22°C maximum. Juices can besides be hot-filled. This awarding is in increasing demand, especially in the depression- and medium-capacity range. "Our customers want flexible machines they can also realize new products on," explains Härtel. "Our fillers can process widgets, for example, that release nitrogen into beers low in carbon dioxide when the tin's opened. This produces a very creamy and compact head, just like a freshly tapped draft beer."
Pneumatic lowering device
The compact Innofill Can C tin can filler, besides, is becoming increasingly pop with pocket-size and medium-sized breweries. KHS has therefore optimized it further. Here, the pitch circle has been enlarged from 720 to one,800 millimeters, enabling car outputs of upwards to 50,000 cans an hr to now be accomplished on 60 filling valves. With this capacity, the Innofill Tin can C can at present also be integrated into lines with higher outputs, particularly in combination with process engineering science such equally the Innopro Paramix C blending system, flash pasteurizer, or CIP module. This ways that beverages tin also be candy and canned in the medium-chapters range on space-saving KHS systems right down the line. What's more than, the compactness of the Innofill Tin C is especially compelling. The filler, seamer, service module, cladding, and control chiffonier come pre-assembled on delivery so that the plug-and-produce system can go into performance more than or less immediately.
In addition, the filling valves on the computer-controlled filling arrangement are equipped with electromagnetic induction catamenia meters. They ensure compatible filling levels and that headspace of precisely the same size are created in the cans. The energy-efficient drives also support a resource-saving production procedure. Additionally, every bit on all KHS machines, the tin can fillers use servomotors and servo drives of the highest energy efficiency.
Integrated seamer system
The Infill Tin C includes a tin seamer from Ferrum, an internationally renowned company in this field. In addition to a arrangement with three seamer spindles, versions with six or eight are also available for higher outputs – these with automatic height adjustment.
The tin can fillers tin can also be supplemented by an Innoket Neo labeling machine, for instance, that dresses the containers with cocky-adhesive labels. "This can be useful if small batches of individual cans are also to be produced," Härtel remarks.
