Vacuum Sampling
Particle size analytical results are most applicable when samples drawn are representative and the appropriate dispersion techniques are used. The majority of variation in particle sizing measurements is traceable to either incorrect sampling or sample preparation.
When measuring the PSD of a powdered solid, the results will have little value unless the analytical sample is representative of the bulk from which it was taken. The magnitude of this problem may be realized by considering that the characteristics of many kilograms of material are assumed on the basis of analyzes carried out on gram or even milligram sample quantities.
The vacuum sampling system has been developed to provide a flexible method of taking powder samples from powder storage & handling systems. The system is complete with a sampling point which is located in the powder storage hopper or other powder handling vessel. The sampling station can be remotely located to suit the plant operation. This station can even be located on a different floor if this is required.

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.

Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.

How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
