EFFICIENT CONTACT DRYING MADE BY LÖDIGE
In the world of industrial drying processes, the name LÖDIGE stands for quality, efficiency and innovation. Our contact dryers are benchmark technology using the latest techniques for industrial drying. We supply not only to the cosmetic, chemical and pharmaceutical industries, but also to the environmental and plastics sectors. Our solutions are proven all over the world.
CONTACT DRYING: ONE PROCESS, MANY ADVANTAGES
Contact drying is a highly effective process for removing moisture from products. It is based on the principle of direct contact between the moist product and a hot surface, resulting in rapid evaporation of the moisture. Unlike other drying methods where heat is transferred indirectly, contact drying allows heat energy to be transferred directly to the product.
It also allows precise control of the entire drying process. This is particularly important to ensure even drying of the product and to avoid overheating or damage. Contact drying is suitable for a wide range of products such as food, powders, granules or liquids. LÖDIGE contact dryers, such as the DRUVATHERM® Vacuum Shovel Dryer, make optimum use of these principles and offer the following advantages:
- High energy efficiency: Direct heat transfer reduces energy loss.
- Quick drying: Direct heat transfer provides faster drying times, ideal for temperature sensitive products.
- Compact design: Our dryers are designed to save space and fit into tight production environments
- Low risk of contamination: Closed systems reduce the risk of product contamination.
CONTINUOUS OPERATION VS. BATCH OPERATION
LÖDIGE provides both contact drying systems for continuous and batch operations. Each process has its specific applications and advantages. The continuous drying process is ideal for processing large quantities with consistent quality. Our continuous Granulation Dryer combines convection and contact drying for efficient drying at low temperatures.
On the other hand, discontinuous operation offers optimum flexibility for batch processes and a wide range of product types. With the innovative LÖDIGE Shovel Dryer, processes can be adapted to different requirements in a flexible manner. Both systems operate according to the fluid bed principle generated mechanically and first developed by LÖDIGE: this ensures intensive product movement and therefore efficient drying.
CONTACT DRYING ALWAYS THINKING AHEAD
The fluid bed principle developed by LÖDIGE is an innovation in the field of drying technology. This mixing principle combines the efficiency of centrifugal force with the vortex movement to ensure uniform and effective drying.
By implementing this process in our contact dryers, the product to be dried is set into an intensive three-dimensional movement. This greatly increases the frequency of contact between the product and the heated surface, resulting in very short drying times.
The fluid bed principle not only ensures improved heat transfer and efficient use of energy, but also minimises the risk of product damage and guarantees a high-quality end product. The use of this process in LÖDIGE contact dryers such as the DRUVATHERM® Vacuum Shovel Dryer enables gentle thermal treatment of products at low temperatures and under vacuum. This is particularly advantageous for temperature sensitive or perishable products.

VERSATILE DRYING TECHNOLOGY FOR A WIDE RANGE OF INDUSTRIES
Our contact dryers are successful across all sectors - from cosmetics to chemicals, pharmaceuticals, the environment and plastics.
In the cosmetic industry, our contact dryers provide efficient and gentle drying of products such as creams, lotions and make-up. By precisely controlling drying parameters, we can ensure that products retain their desired consistency and quality.
In the chemical industry, our solutions are used to dry chemical compounds and materials. By precisely controlling temperature and airflow, we achieve fast and efficient drying without affecting the chemical composition of the products.
In the pharmaceutical industry, LÖDIGE contact dryers play an important role in the production of medicines. They enable gentle drying of active ingredients and help to ensure the stability and efficacy of medicines.
In the environmental sector for example, our contact dryers are used to dry sewage sludge to reduce its volume and enable safe disposal. Our dryers can be heated directly or indirectly with a wide range of media and can handle viscoplastic product phases. In a vacuum, the boiling point of water or organic solvents is lowered for gentle, energy-saving drying.
We also offer customised solutions for the plastics industry. Our contact dryers enable efficient drying of plastic granules to reduce their moisture content and ensure optimum processing. This helps to improve product quality and reduce waste.
WE ARE CERTIFIED & APPROVED
