Practical example: Use of an orbital cleaner in a spray dryer

A problem arising in this particular case was the size of the insertion opening at the top of the dryer. It has a diameter of only 200 mm (7.9”). Many orbital units need a larger insertion opening than this because of the length of their nozzles.

Cleaner Recommended working pressure Flow rate Insertion opening

Twister max. 16 m 2.7 – 5.8 m³/h min. Ø 100 mm

Typhoon max. 17 m 5.6 – 10.5 m³/h min. Ø 130 mm

Tempest max. 19 m 12 – 23.4 m³/h min. Ø 210 mm

Tornado max. 27 m 14.6 – 22.7 m³/h min. Ø 220 mm

Tornado 4 max. 33 m 14.2 – 47.4 m³/h min. Ø 250 mm

Another requirement was to reduce the time or cleaning and optimize time for production. The tank cleaner Tornado 4 fulfilled these requirements perfectly.

Due to the small insertion opening a Tornado 4 with short nozzles was constructed. In the cleaning process the tank cleaner is suspended on a hose 2 m under the top of the dryer and stays in this position during the whole cleaning process. This achieves efficient and excellent cleaning results.

Using the Tornado 4 saves 50 h per year for cleaning which can be used for production now.
