Sucafina and Beyers Koffie partner with CEE for their net-zero transition

Future-proof coffee roasting

 


The coffee roasting industry today faces many challenges. Mitigating the impact of climate change while replacing traditional methods with more sustainable solutions is but one of them. To meet net-zero targets, the sector needs to eliminate fossil fuels. But until now, no technically and economically viable solutions have been available on an industrial scale. Finally, standing out from the crowd is crucial in the highly competitive coffee market.

Energy-efficient and hyper-precise drying of construction materials

Like many other industries, the building materials sector grapples with the balancing act between sustainability, technicality, and profitability. Due to its traditionally energy-intensive production processes, the industry's energy cost entails, on average, 20% of its total spending. The drying process, in particular, consumes a large part of this energy cost because large quantities of water need to evaporate. Drying technology needs to be hyper-precise to reach the right moisture level in the end product, which is critical for construction materials such as bricks or fire-resistant panels. On top of that, the sector cannot escape the trend toward decarbonization. Finally, the nature of drying implies high temperatures; therefore, a safe production process is paramount.

In search of an innovative solution, Promat and ETEX called upon CEE. Promat is the Belgian fire-resistant building materials and high-temperature insulation division of ETEX, a group specializing in the production of building materials. In alignment with their ambitious decarbonization goals, the group collaborated with us to co-develop an innovative treatment and drying process in an atmosphere of 100% superheated steam (SHS). Thanks to our expertise and full-scale section lab, we expedited the transition from test to full-scale application in a four-month time span.

 


High precision

We built an SHS drying tunnel with eight separate drying zones. The temperatures, moisture content, and recirculation speed of every zone are controlled for precise reproduction of the recipe over the tunnel's length.

Our SHS treatment of fire protection construction materials is designed to preserve an exact quantity of moisture in the material. This feature significantly enhances the fire-resistant performance of the material, even in the most stringent conditions, providing a robust and safe final product. 

Steam drying allows for better process control, more homogeneous results, and improved quality overall.

nergy-efficient

Many traditional industrial drying processes use air to extract moisture from the product. This is an energy-intensive method. The cooled and moist air is expelled, with, at best, some of the energy recovered to the air inlet. The dry air mass flow at exit temperature defines the heat losses and, thus, the energy consumed by the process.

By switching to SHS drying and reducing the use of fresh air significantly, CEE's solution reduces Promat's energy consumption by 20 to 50% compared to hot air drying. It also simplifies latent heat-recovery of the vapor produced. In combination with solutions like high-temperature heat pumps and mechanical vapor recompression (MVR), our technology can recover up to 95% of process energy. For the second drying line, in total, 900 kW of heat is recovered from the evaporated water and re-injected with 150 kW input to the heat pump.
