4.1 General description
The Alfa Laval Toftejorg SaniMxxxx SB series are tank cleaning machines intended for industrial use in closed tanks, vessels
and containers under typical CIP procedures. They have a broad range of application areas within pharmaceutical, food,
dairy and chemical industries.
The Alfa Laval Toftejorg SaniMxxxx SB is a sanitary cleaning device of the rotating fan spray type for permanent installation
that provides either a 270° upward cleaning pattern or a 360° cleaning pattern. The machine is designed to be completely
self-cleaning as proven by the EHEDG test method. If Installed according to the description on page 14, the Alfa Laval Toftejorg
SaniMxxxx SB is completely self-draining in the shown position and completely inspectable. All product contact surfaces are
AISI 316L stainless steel or polymer material that conforms to FDA21CFR§177 and EU 10/2011. For the Alfa Laval Toftejorg
SaniMxxxx SB plastic material that meets the requirements of 3-A Sanitary Standard 20-## is used. For the Alfa Laval Toftejorg
SaniMidget SB/UltraPure a USP Class VI plastic material is used.
The unique design is totally free of weldings, threads, screws and press-fits to facilitate self-cleanability. The cleaning device
is lubricated by the cleaning media. No oil, grease or other lubricants are used.
The Alfa Laval Toftejorg SaniMxxxx SB is designed for use in pharmaceutical, biotechnological, food and dairy processing
applications. It may be used in reactors, mixing/processing tanks, spray dryers and other process equipment with a volume
from 7.5-220 m³ (2-60,000 US gallons)*. For larger volumes, multiple Alfa Laval Toftejorg SaniMxxxx SB’s may be applied.
* to comply with EU 10/2011 the minimum batch size should be considered. Declaration of EU 10/2011 conformance can be
supplied on request.
Application assistance and recommendations for optimal position is available.
For use in explosive hazard zones the ATEX/IECEx version can be used, provided it is installed according to safety instructions
in local regulations.

SaniMidget/SaniMagnum/SaniMega SB
4.2 Functioning
The flow of cleaning media comes through the down-pipe, flushes the connector and exists through the bearing surfaces, slots
and leakage passages. This causes the head of the Alfa Laval Toftejorg SaniMxxxx SB to rotate, with fans of water laid out in a
swirling pattern on the entire perimeter exposed to the spray pattern. This generates a vibrating impact in the impact pattern
and a dynamic cascading flow that covers all internal surfaces of the tank, vessel or reactor.
The Alfa Laval Toftejorg SaniMxxxx SB is (as the rest of the UltraPure and Sani portfolio) designed according to GMP – compliant
materials, self-cleaning and drainable. The self-cleaning feature of the device is due to the unique design that includes cleaning
of the downpipe. The device is designed with no hindrance to gravity draining. The patented easy assembly and disassembly of
the device allows for only one clip to be used and without any press fits. Upon removing the clip this ensures that no parts can
fall into the tank (the Alfa Laval Toftejorg SaniMxxxx SB must be held in one hand and the clip in the other hand).

4.3 General safety and installation instructions
It is recommended to install a filter with mesh size 250 µm (0.01”) in the supply line to avoid particles, scale etc. from clogging
the inside of the cleaner. However, particles up to 0.8 mm can pass the cleaning slots in the rotor.
Before installation, all supply lines and valves must be thoroughly flushed to remove remains from welding, grinding dust,
scale and other foreign matter. During handling and installation handle the machine with care in order not to damage the
fine surface of the machine.
Randomly selected Alfa Laval Toftejorg SaniMxxxx SB machines are tested at the factory before shipping, in accordance
with “Test Requirements for SaniMxxxx SB”.
Warning: Precautions shall be made to prevent starting the cleaning operation, while personnel are inside the tank or
otherwise can be hit by water jets from the cleaner head.
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, the EU-ATEX/IECEx Directive and other relevant Directives and shall be CE-marked before it is set into operation.
