Switzerland is a leader in coffee processing: from roasting and grinding to brewing. The leading manufacturers of fully automatic coffee machines for the catering industry are based in Europe, with three of the biggest ones located in Switzerland.
CEKA has built up extensive expertise in this market. In close partnership with HELFEZI, another leader in technical excellence within the coffee sector, renowned for its top-quality grinding discs, CEKA has developed an integrated system solution for built-in grinders for fully automatic commercial coffee machines in the catering sector. Designed for durability, performance and easy, flexible integration into machine designs, these premium mills combine the experience and expertise of both companies.
Rising standards in coffee preparation
Coffee preparation in the hospitality industry must meet ever-increasing standards. Guests expect consistently high quality, operators rely on reliability in day-to-day operations, and manufacturers are seeking unique technological features. One component plays a central role in this, yet is often underestimated: the coffee grinder. It influences grind size, extraction and consistency, and thus directly affects flavour, aroma and crema.
The built-in grinder as the heart for fully automatic commercial coffee machine
The fineness and consistency of the grind determine how well the coffee’s components dissolve during the brewing process, thereby shaping the coffee’s flavour, balance and character – in other words, how harmoniously the aromas unfold in the cup.
The grinder is one of the key factors in meeting today’s high standards for top-quality brewed coffee. For operators, it is not just the quality of the individual cup that matters, but also factors such as consistency, controllability, durability and ease of maintenance.
Top-quality coffee, even in small quantities
High-quality grinding allows for better extraction of the coffee’s aroma, thereby reducing the amount of coffee needed to make a perfect cup. This reduction in coffee usage leads to savings on preparation costs and helps protect the environment. We estimate that a significant amount of coffee can be saved compared to traditional standard grinders.
Why the built-in grinder is underestimated
In many fully automatic commercial coffee machines, the grinder is still treated as an invisible, standardised secondary component. The focus is primarily on keeping production costs as low as possible and on convenience rather than quality. We, however, are convinced that good coffee requires high-quality grinding to optimally extract the ingredients and deliver a premium in-cup experience – from flavour to crema – consistently over a long period. This, however, requires a different set of priorities and elevates the grinder from its shadowy existence to the status it deserves: that of one of the centrepieces of high-quality coffee preparation.
Weaknesses of traditional built-in grinders in fully automatic coffee machines for the catering industry
Actually, we’d rather focus on finding better solutions than on criticising! Nevertheless, we feel it is appropriate to highlight a few issues here.
Traditional built-in grinders are not designed for consistent quality, but primarily for cost optimisation at every level.
The service life of standard grinding discs is extremely limited, and their cutting geometry fails to achieve uniform particle size distribution over time.
The grind setting is usually imprecise or only possible in coarse stages, which at best claims to allow for a rough adjustment to different coffee varieties, roasts or humidity levels.
Added to this is a lack of modularity, which does not allow the grinder or grinding discs to be specifically tailored to particular requirements and installation situations.
Mechanical instability, play in the bearings or unbalanced components also lead to a noisy grinding process and increased wear.
In practice, this manifests as inconsistent coffee quality, more frequent cleaning and maintenance intervals, and unwanted downtime.
Consequently, service costs, operating costs and the total cost of ownership rise, whilst the machine’s – and, above all, the beverage’s – actual quality promise is not reliably fulfilled.
Our conclusion: unsatisfactory from A to Z.
Our response: Top-quality built-in grinders
With the EMV-65 and EMH-65 built-in grinders, we offer a comprehensive solution to the shortcomings of traditional approaches in the coffee grinder industry. Combined with HELFEZI grinding discs, the result is a built-in grinder designed without compromise for grinding quality, durability and consistent performance. The overall concept combines precise mechanics, intelligent process control and high serviceability to create a solution for professional, continuous use.
Key technical features of the new built-in coffee grinders:
Modular design
The modular design allows for flexible integration into different appliance architectures and installation scenarios. Manufacturers retain maximum design freedom, whilst precision and mechanical stability are fully maintained.
Stepless, high-precision grind adjustment
The stepless adjustment allows the grind size to be precisely tailored to the bean, roast and intended use. This enables the grind to be optimised with precision and consistency, without the compromises associated with coarse, fixed settings.
HELFEZI grinding discs, Swiss Made
HELFEZI grinding discs meet the highest standards of grinding quality and reproducibility. The specially developed, environmentally friendly TDC coating, which is food-grade certified (FDA / USDA) and biocompatible, significantly reduces wear, friction and corrosion, requires no running-in and ensures consistent grinding quality. The exceptional edge sharpness guarantees an extremely long service life.
Portioned feeding with complete emptying
After each brew, the grinder is run until completely empty, thereby consistently preventing dead space. The result is fresh ground coffee for every cup and consistent sensory quality throughout operation.
Speed adjustment
The variable speed allows the grinding process to be precisely tailored to different coffee varieties and desired flavour profiles. This enables optimal control of heat generation, particle structure and grind characteristics.
Minimal maintenance
Easily accessible, removable components significantly simplify cleaning and servicing. This reduces downtime, lowers operating costs and increases reliability in daily use.
Collaboration between CEKA and HELFEZI: Driving technical excellence
CEKAtec AG and HELFEZI AG complement each other in terms of their experience and expertise in the coffee sector. This partnership has resulted in an integrated system solution for high-end built-in grinders, designed for durability, performance and simple, flexible integration into machine designs.
