General Description
The Toftejorg SaniJet 20 is a tank cleaning machine intended for industrial use in closed tanks for
processing storage and transportation. There is a broad range of application areas within
pharmaceutical, food and chemical industries.
The Toftejorg SaniJet 20 is a sanitary cleaning device of the rotary jet head type for permanent
installation that provides a 360° indexed cleaning pattern. Provided it is installed in an upright position,
the Toftejorg SaniJet 20 is completely self-cleaning and self-draining, and it has an integrated self-
cleaning down pipe (patent pending). The drive mechanism is located outside the tank or process
equipment, leaving a minimum of parts to be submerged into the product. All product contact surfaces
are AISI 316/316L, duplex SAF 2205, Ti Grade 5 and USP Class VI and/or FDA approved polymer
materials such as PEEK, E-CTFE, EPDM and Viton.
No threads or screws have been used in the product contact areas.
The cleaning device is lubricated by the cleaning media. No oil, grease or other lubricants are used.
The Toftejorg SaniJet 20 is available in media driven or motor driven (electrical/air) versions. The motor
driven versions are equipped with a magnetic clutch providing a leakage-proof transmission. The motor
driven versions provide an effective drive for low flow machines in rough environments. The air motor
has variable speed in order to adjust cleaning intensity. The air driven version is covered by Instruction
Manual IM-TE91A793 and the media driven version is covered by Instruction Manual IM-TE91A792.
The Toftejorg SaniJet 20 is designed for use in pharmaceutical, biotechnological, food and dairy
processing applications. Tanks and vessels between 0.5-30 m3(130-8,000 US gallons). The design
makes the Toftejorg SaniJet 20 especially well suited when processing high viscous, foaming or
thixotropic products and in chemical processing applications, where product cross contamination is
unacceptable and must be avoided.
For use in explosive hazard zones the media driven and the air motor version can be used, provided it
is installed according to safety instructions in local regulations.
The version with standard electrical motor must not be used in explosive hazard zones.

General Description (continued)
Functioning
Toftejorg SaniJet 20 consists of 3 main parts: The Drive unit with flow inlet and the Base housing
placed outside the tank, and inside the tank: the Down pipe with the rotating Outer tube and the
Cleaner unit.
The flow of the cleaning fluid passes from the inlet
through the Base housing, through the Down pipe,
into the Cleaner head and out through the Nozzles.
The Outer tube of the Down pipe is rotably
suspended on a Stationary shaft with a Ball bearing
inside the Outer tube. The Drive mechanism rotates
the Outer tube with the Cleaner unit around the
vertical axis. Via a set of Bevel gears on the
Stationary shaft and the Cleaner head, the Cleaner
head with the Nozzles is simultaneously rotated
around the horizontal axis in a fixed relation thus
moving the nozzles and the jets 360°around in the
tank making a pre-set indexed cleaning pattern.
The Toftejorg SaniJet 20 utilises the patented “Golden Section” cleaning pattern. The distance between
the tracks of the jets ensures an efficient removal of remaining product from the tank surface right from
the beginning of the cleaning sequence, allowing for short cleaning time.
Example – 2 nozzle machine:
0.8 min. 2.3 min. 6 min.
The time 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, less than 1
min. could be sufficient while in cases of more heavy soilage (high viscous, sticky substances, etc.) a
more dense pattern/longer time will be needed.

General Description (continued)
Machine with External Motor Drive
The machine is driven by a gear motor mounted on top of the Inlet housing. Via a Magnetic clutch the
rotation of the gear motor is transmitted from the outside through a closed wall to the Output shaft
placed inside the Inlet housing. The Output shaft is in mesh with the Down pipe and rotates the Down
pipe in the same way as in the media driven version.
The output shaft of the gear motor is equipped with a Rotor with permanent magnets. The rotor is
placed inside the cavity in the Motor flange, made by the cup protruding into the liquid chamber in the
Inlet housing. The cup is welded to the motor flange as a hermetic sealed closed wall between the
liquid chamber and the outside. The magnetic field from the permanent magnets is transferred through
the wall, to a ring with permanent magnets inside the Output shaft, which is placed around the cup on
the inside the liquid chamber.

General Description (continued)
The machine with Electrical gear motor (at frequency 50 Hz) is rotating at fixed speed: 14 RPM with
2xø2mm nozzles and 6.5 RPM with 4xø4.2mm nozzles. The machine with 2xø3.8mm nozzles is
available in both a High Speed (14 RPM) and a Low Speed version (6.5 RPM).
Self-cleaning
Apart from the main flow flushing the inside of the Base housing and the Down pipe, and thereafter
forming the jets through the Nozzles, fluid is flushed through all internal cavities, through Bevel gear,
Ball bearings and gabs between moving parts and is finally also used for cleaning of the outside
surfaces of the machine.
From the gab between the Base housing and the rotating Down pipe, a cleaning jet is directed against
the Down pipe, thus loosening and removing product remains on the outside. A liquid film flushing all
around the tube further assists by continuously transporting away loosened product remains. The front
of the Cleaner head is flushed by a liquid flow from the gab between the Cleaner head and the
Retaining ring.
In order to ensure a proper self-cleaning, the machine must be installed in an approx. upright position
and the inlet pressure must be min. 3 bar.
In the bottom of the Cleaner head, in the Retaining ring, the machine is equipped with a hole to ensure
self-draining. This self-draining is only ensured, if the machine is installed in an upright position.

General Description (continued)
Cleaning Pattern, The Golden Section
The patented Golden Section cleaning pattern (EP-Patent No.: 0495883. US-Patent No.: 5,279.675) is
unique in building up the pattern in an ultimate uniform way. The pattern starts very coarse and refines
itself in a step-less way by laying out the tracks approximately in the middle between the two most
distant tracks already made. This means that the jets always clean the areas containing most
remaining product, and thereby remove as much deposit as possible in the shortest possible way.
In case a complete cleaning pattern is not required, it will be possible to reach the same cleaning level
within half the time and by using half the amount of cleaning fluid compared to a traditional step-wise
cleaning pattern. Furthermore, due to the uniform cleaning pattern, the cleaning can be stopped at any
time, whereas with traditional non-uniform cleaning pattern this would not be advantageous. However,
after the complete cleaning pattern has been established, the difference between the Golden Section
and the traditional stepwise cleaning pattern is negligible.

Installation
General Installation Instructions
The Toftejorg SaniJet 20 is designed to be installed in a vertical upright position.
It is recommended to install a filter with mesh size 250 µm (0,01") in the supply line in order to avoid
particles, scale etc. from clogging inside the machine. It is essential to avoid fine solid particles, such
as fine sand, in the cleaning fluid as they will increase wear considerably. This is particular important in
case of recirculation.
In order to prevent accidental leakage of cleaning fluid into the tank it is recommended to install a shut-
off valve close to the machine inlet. This will also prevent back-flow of liquid from the tank through the
machine in case the cleaner head is submerged and there is an over-pressure inside the tank. The
installation and operation shall be made in such a way that the draining of the machine is ensured.
It is recommended that the fluid valve fitted is of a type that prevents hydraulic shocks, which may
cause severe damage to the entire installation.
Before installation, all supply lines and valves must be thoroughly flushed to remove remains of
welding electrodes, grinding dust, scale and other foreign matter.
During handling and installation handle the machine with care in order not to damage the fine surface
finish of the machine.
The Toftejorg SaniJet 20 machine has been tested in a test tank according to ALTEQ test procedures
at the factory before shipping.
Note: Do not try to turn Nozzle head by hand, since this may damage the Gear. Nozzle head can be
turned by blowing air from an air pistol through the inlet connection of the media driven machine or the
intake port of the air motor.
Note: The machine shall be installed in accordance with national regulations for safety and other
relevant regulations and standards. In EU-countries the complete system must fulfil the EU-Machine
Directive and depending of application, the EU-Pressure Equipment Directive and other relevant
Directives and shall be CE-marked before it is set into operation.
