De Lindor Capsule©: Vacuüm drogen en coaten in één machine

With our new Vacuum Dryer/Coater, you can vacuum dry products and coat them using just one machine. Applications include: rapid and effective drying of pharmaceutical components (such as APIs), impregnation and drying of catalysts, liquid and gas reactions with powders, soaking special plastic compounds, etc.

A number of Lindor Capsules have now been supplied for pharmaceutical applications and fine chemicals. In addition, we have a Lindor Capsule available for customers at our test centre in Dordrecht.

Advantages of vacuum for drying

Vacuum enables a lower evaporation temperature, at which fluid becomes a gas. This allows drying under vacuum at a lower temperature, or faster drying at the same temperature. For example, the boiling temperature of pure water at sea level is 100°C, but on Mount Everest, where the air pressure is much lower, it is only 69°C.

This advantage results in far better preservation of product properties due to a lower drying temperature combined with lower energy consumption.

Advantages of vacuum for coating

For coating and impregnation, the advantage of vacuum is that a liquid can penetrate and adhere deeper and more rapidly into the pores of a particle. The reason for this is that in the absence of air, liquid has a free path in and around the particle, and is not hindered by the air molecules present. A particle with pores that do not contain air, absorbs the liquid, so to speak.

Proven technology

The Capsule Vacuum Dryer is a new development in Lindor technology. The core of the vacuum dryer is similar to the conventional Lindor Mixer in having a rotating drum with fixed vanes. As a result of rotation and gravity, powder or granulate flows evenly through the drum. Because an agitator is not used, the particles are practically free from shearing forces. The combination of this technology with vacuum ensures even temperature distribution, shorter drying times and maintains the product’s integrity.

Next generation

The new Capsule Vacuum Dryer differs not so much in mixing technology, but more so in its design. The drum has a double wall with a fully welded insulation layer, special seals that can withstand vacuum, and a rail structure that ensures a safe, quick and simple method for disassembly and correctly assembly.

Easy and quick to clean

The rail structure makes cleaning the Capsule Vacuum Dryer easy, quick and thorough. It is a further development of the retractable inlet and outlet (QSR), that has been available on conventional Lindor mixers for 10 years.

Available for varying batch sizes

The Vacuum Dryer can be supplied in various batch capacities. Associated equipment such as hot water units, oil heaters, vacuum pumps, special filters and liquid injection can be supplied as an integral part of the system.
