Glatt spray system for a Glatt fluid bed coater GFC 2200


Processing of liquids of any kind.

With consistently high product quality and maximum process reliability.

Constant product quality! Whether thin solution, thick suspension, waxes, polymers or melt.

Process reliability and constant product quality are essentially determined by uniform atomization of the liquid raw material. Parameters such as spray pressure, droplet size, spray cone and droplet velocity must be reliably controlled. Nozzle design and distribution in the fluid bed or in the spouted bed are equally important. We combine decades of experience with modern simulation and modeling calculations to achieve the optimum distribution of the liquid in the process chamber.

Uniform distribution of the liquid raw material to all nozzles must be ensured at different spray rates and different viscosities. Whether thin solution, thick suspension, polymers or a melt – for example of lipids, fats or waxes – we offer the right solution. Whether simple peristaltic pumps or ring distributors with flow meters for each nozzle, we have already built (almost) everything, depending on the requirements of the process and the customer’s wishes.

Water or organic solvents

If the liquid does not become stable enough with water or by melting, organic solvents can be the solution. We have worked with many different solvents, even in mixtures and at elevated temperatures. Safety and environmental protection are then, of course, paramount.

Spraying hot liquids of all kinds

It is not unusual for liquid starting materials to have to be heated in order to be sprayed. Whether it’s a supersaturated solution, a melt in its own hydrated water, or molten waxes and polymers, Glatt has extensive experience in hot melt processes as well as in the safe distribution and metering of other hot liquids. This includes options for cleaning fluid lines, distribution fittings and measuring instruments at the end of production.

Hygienic, explosion-proof demountable spray nozzles for maximum process reliability

Glatt sets standards in process safety and plant availability with hygienic, explosion-proof demountable spray nozzles. Continuous fluid bed systems and spouted bed systems with multiple spray nozzles continue to run with the same product quality and system safety. Nozzle protection saves plant downtime, increases personal, operational and occupational safety, and reduces potential sources of operator error. In addition, the empty outer tube can be washed at the same time as the washing process.
