STA Impianti’s “green machines”: roasting machines dedicated to savings and sustainability

With more than thirty years of specialization in the designing and marketing of coffee processing machines and plants, STA Impianti also boasts a long experience in upholding sustainability standards. The Bologna based company has always been focused on energy savings and now it has reinvented itself with a portfolio of better performing, technologically advanced and energy-efficient roasting machines.

When less is best

STA Impianti has always been manufacturing machines with combustion chambers completely made of heat resistant steel. After the latest technology upgrade, the company has completely removed the ceramic fiber, which was used for the combustion chamber’s thermal insulation and to protect workers in accordance with safety regulations. STA decided to implement this new technology after years of research, as it guarantees excellent results and a never before seen flexibility in the roasting process. Such an innovative choice allows the company to uphold high operational security standards and sets the company apart from every competitor that still uses insulating materials such as cement, firebricks, ceramic fiber or other similar products which can leave harmful residues. The path STA has chosen allows the customers to improve the quality of their coffee both from an organoleptic and security perspective.

Certified savings for customers and the environment

Many clients are already employing the new STA solutions, thanks to which they have considerably improved roasting uniformity and yield, while dramatically lowering the preheating and roasting times, all of which translates in significant gains in term of energy, gas and labor needed for the process. Using the latest roasting machines, clients can achieve global energy savings of between 20% and 25% over the most common devices on the market. Such data can be constantly verified from electricity, gas and time meters installed on our roasting machines; this data is then recorded in the work sheet of the product. Thanks to this technological evolution. the client is able to obtain a higher quality product, uncontaminated by polluting material residues, as well as emissions from combustion recirculation, being also capable of tracking useful metrics in real time in order to calculate processing costs.

Not just hardware

The company’s mechanical innovations are complemented by software innovations, which allow the full control of all roasting machine’s parameters through comprehensive customization and the deployment of specific interfaces for plant management. The software was developed by STA and, together with next-generation electronic components, allows for the automatic tracking and creation of production batches, thanks to the machines’ ability to communicate with the business database. This enables the immediate collection of production and inventory data, as well as laboratory data to check incoming coffee shipments, for a full remote, real time management of the plant and, ultimately, better production efficiencies and a higher quality product.
