Introduction
With a new revolutionary patented design, the Toftejorg MultiJet 25 introduces a new generation of
tank cleaning machines.
Based on more than 30 years experience from practical tank cleaning and production, the Toftejorg
MultiJet 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 operating and maintaining your
tank cleaning machine. The key to long life for your tank cleaning machine will always be a system of
carefully planned maintenance; you will appreciate that a tank cleaning machine which has a rough and
dirty job to do will need more frequent attention than one working in ideal conditions.
It is in your own interest to get the best and most economical performance from your tank cleaning
machine. Neglect of maintenance means poor performance, unscheduled stoppages, shorter life and
expense. Good maintenance means good performance; no unscheduled stoppages and better total
economy.
You will find the information contained in this manual
simple to follow, but should you require further assistance,
our Customer Service Department and world-wide net of
Distributors will be pleased to help you. Please quote the
type and serial number with all your enquiries; this will help
us to help you.
The type and serial number are placed on the gear house
of the tank cleaning machine.

General Description
The Toftejorg MultiJet 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
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.
The areas behind the Screws on the Cone are
cleaned through small spray holes behind the
Screws. 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.

For devices with tapered thread connections to the down pipe, it is
recommended that you secure the connection in a manner appropriate
for the application. Subject to the intended use environment and any
inhouse user requirements or policies, an adhesive such as Loctite No.
243 or equivalent could be used. Other methods could be acceptable
and subject to customer preference.
Sanitary connection
Use Cone with Gasket.

Performance Data
Flow Rate Horizontal Throw length at static condition
Cleaning time, complete pattern
Effective throw length is defined as impact in
centre of jet 250 mm water column (50 lbs/sq.ft.).
However, effective throw length varies depending
on jet transverse speed over surface, substance
to be removed, cleaning procedure and agent.
Note: Throw lengths are measured as horizontal
throw length at static condition.
Vertical throw length upwards are approx. 1/3
less.
The inlet pressure has been measured
immediately at the machine inlet. In order to
achieve the performance indicated in the curves,
pressure drop in the supply lines between pump
and machine must be taken into consideration.
