3. General Description
The Scanjet Bio 25 is a media driven and lubricated tank cleaning machine. No
lubrication substances such as oil, grease etc. are used. All materials in contact
with the machine meet the general standards for hygienic process. Ceramic
and tungsten bearings are standard for an extra long service life. The unique
design of the Scanjet BIO 25 makes it completely self-cleaning and self-cleaning.
There are no interior pockets where water and dirt can accumulate, making this
machine one of the best choices for hygenic applications.
Functional Principle
When cleaning media enters the machine it fi rst passes through a turbine and a
worm gearbox, then a nozzle housing leading it out through the nozzles and into
the tank. The turbines rotation drives the worm gearbox, making the machine
rotate around its own axle and at the same time, the nozzle housing is forced to
rotate clockwise.
A combined motion of the machines body and nozzle housing creates a criss-
cross cleaning pattern inside the tank. After 6 1/8 rotation of the nozzle housing,
a fi rst course pattern has been created. This process is repeated 8 times, each
time indexed from each other until a full cleaning pattern has been created.
When this is fi nalized, after 47 rotations of the machine body, or 49 rotations of
the nozzle housing, the fi rst cycle will be repeated.
Cleaning of tanks is a process depending on a number of factors; soilage, distance
between nozzles and tank walls, cleaning media, temperature etc. All of these
factors need to be considered before a proper cleaning can be accomplished.
The rotation speed of the machine idepends on fl ow rate through the machine.
Higher fl ow rate makes the turbine spin faster and because of this the machine is
equipped with different turbines according to nozzle size and intended operating
parameters.
