Introduction
Based on more than 30 years of experience from practical tank cleaning and production, the Toftejorg
SaniJet 25 has been developed to meet the highest demands for efficiency, reliability and hygiene
within food and beverage, pharmaceutical and biochemical industry.
This manual has been prepared as a guide for the persons who will be only operating your tank
cleaning machine.
If the Toftejorg SaniJet 25 stops rotating unintentionally, please return the machine to Alfa Laval Tank
Equipment A/S.
The type and serial number are placed on the gear house
of the tank cleaning machine.
Note: The illustrations and specifications contained in this manual were effective at the date of printing.
However, as continuous improvements are our policy, we reserve the right to alter or modify any unit
specification on any product without prior notice or any obligation.

General Description
The Toftejorg SaniJet 25 is a media driven and media lubricated tank cleaning machine. No lubricating
substances such as oil, grease etc. are used. All materials are selected for contact with food, and the
machine is self-cleaning i.e. all internal and external surfaces are cleaned.
Functioning
The flow of the cleaning fluid into the machine passes through a turbine, which accordingly is set into
rotation. Through a gear set and a driver tube, the turbine rotation is transmitted to the Cleaner Head.
The combined motion of the machine Body and the Nozzles ensures a fully indexed tank cleaning
coverage. After 55/8 revolutions of the Hub cover with Nozzles (53/8 revolutions of the machine Body),
one coarse cleaning pattern is laid out on the tank surface and the first cycle has been made. During
the following cycles, this pattern is repeated 7 times, each of which is displaced, and the pattern
gradually becomes more dense. Finally, after 8 cycles - a total of 45 revolutions of the Hub Cover with
Nozzles (43 revolutions of the machine Body), a complete cleaning pattern has been laid out, and the
first pattern is repeated.
This is illustrated below for spherical tank with the machine placed in the centre:
1st cycle 2nd cycle 3rd cycle 4th cycle
The number of cycles needed to perform a proper cleaning depends on type of soilage, distance,
cleaning procedure and agent.
For substances that are easily mobilised, i.e. are easy to remove, one cycle could be sufficient while in
cases of more heavy soilage (high viscous, sticky substances, etc.) a more dense pattern/more cycles
will be needed.
The speed of rotation of the turbine depends on the flow rate through the machine. The higher the flow
rate is, the higher the speed of rotation will be. In order to control the RPM of the machine for a wide
range of flow rates, the machine has different turbines according to the Nozzle size.

General Description (continued)
Apart from the main flow flushing the gear and the
Hub, and thereafter forming the jets through the
Body nozzles and Hub nozzles, fluid is flushed
through all internal areas, through bevel gear, Ball
bearings and gabs between moving parts and is
finally also used for cleaning of the outside
surfaces of the machine. In the bottom of the
Body, the machine is equipped with a hole to
ensure self-draining. This self-draining is only
ensured, if the machine is installed in upright
position.
