Introduction
This manual has been prepared as a guide for installation and for the persons who will be operating
and maintaining your tank cleaning machine.
The key to long life for your tank cleaning machine is a carefully planned system for preventive
maintenance; you must appreciate that a tank cleaning machine which has a rough and dirty job to do
will need more frequent attention than one working under ideal conditions.
Note: Get the best and most economical performance from your tank cleaning machine. Insufficient
preventive maintenance means poor performance, unscheduled stops, shorter lifetime and extra costs.
Good preventive maintenance on the contrary means good performance, no unscheduled stops and
superior total economy.
The information in this manual is simple to follow, but should you require further assistance, our
Customer Service department and worldwide net of distributors will be pleased to help you. Please
quote the type, article and serial numbers with all of your enquiries; this will help us to help you.
The article number and serial number are placed on the front of the tank cleaning machine, SMR
XXXXXX/YYYY-YYY (article number/serial number).
Warning: Before installing the machine and setting it into operation carefully read the General
Installation Instructions (page 10) and the Safety Precautions (page 11) and take all
necessary precautions according to your application and local regulations.
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 SaniMidget Retractor is a tank cleaning machine intended for industrial use in closed
tanks for processing storage. There is a broad range of application area within pharmaceutical, food
and chemical industries.
The Toftejorg SaniMidget Retractor is a sanitary cleaning device of the rotating fan jets type for
permanent installation that provides a 270° Up cleaning pattern. During the process, the cleaner head
is not extended into the process but completely sealed off from the product area and is therefore not in
contact with the product. The cleaner head is automatically extended when cleaning starts and is
automatically retracted when cleaning is completed. The machine is designed in such a way that it is
completely self-cleaning. If Installed according to drawing on page 10, the SaniMidget Retractor is
completely self-draining in the shown positions. All products contacts surfaces are AISI 316L stainless
steel or FDA approved polymer materials.
No open thread or screws in the product areas.
The cleaning device is lubricated by the cleaning media. No oil, grease or other lubricants are used.
The Toftejorg SaniMidget Retractor is available in media driven or pneumatic driven versions which
means extended by media or pneumatic.
The Toftejorg SaniMidget Retractor is designed for use in pharmaceutical, biotechnological, food and
dairy processing applications. Process equipment with moving internals, and in processes where
permanently installed cleaner heads may have an undesired influence on the process or product.
It may be used in storage tanks, reactors, mixing tanks, spray dryers and other process equipment with
a volume ranging from 0.1-10m³ (27-2,700 US gallons). For larger volumes, multiple Toftejorg
SaniMidget Retractors may be applied.
Application assistance and optimal position recommendation is available
For use in explosive hazard zones both types can be used, provided they are installed according to the
safety instructions in local regulations.
Quality system
The Toftejorg SaniMidget Retractor is designed in accordance with the 3A Sanitary Standards No. 78-
00 as well as the guidelines of the European Hygienic Design Group (EHEDG) and thus complies with
requirements to design, materials, finish and documentation. It is produced according to Alfa Laval
Tank Equipment´s ISO 9001 international Standard certified quality system. All parts are made from
certified material and all non-metal parts are made from FDA-approved materials, 21 CFR § 177

General Description (continued)
Functioning
The Toftejorg SaniMidget Retractor consists of 2 main parts: The drive unit and the base housing. The
base housing includes the piston with the cleaner head.
Media driven
In the cleaning media operated version the
cleaner head extends from the pressure of the
cleaning media and is retracted by a spring.
The cleaning media is directed through the 1” tri-
clamp inlet connection into the housing. The liquid
pressures the piston, which moves forward to
extended position. At the same time the liquid
passes through drillings in the piston to the
cleaner head and out through the slots.
When cleaning is completed the machine is
automatically retracted by an integrated spring
system.
For total drain of the machine the retraction of the
cleaner head can be delayed by adjusting the
evacuation of air behind the piston. Use a
screwdriver and adjust the needle valve on the
rear part of the machine to correct position.
Pneumatic driven
In the pneumatic operated version, the cleaner
head is extended and retracted by an integrated
pneumatic cylinder. The cleaner head is extended
when air is applied to the pneumatic cylinder,
which must be done before cleaning media supply
has started. It is retracted to its initial position
when cleaning is completed by diverting the air
pressure from the pneumatic cylinder. The
pneumatic cylinder can remain extended during a
draining phase without media supply.

General Description (continued)
Functioning
In both media and pneumatic driven Toftejorg SaniMidget Retractor versions, the cleaner head starts
rotating with fan jets due to the flow of the cleaning fluid. It projects a swirling pattern of media through
the tank or vessel which generates a vibrating impact and cascading flow coverage of the total internal
surface of the tank or vessel.
When the cleaning media pressure is shut off, the cleaning media is completely drained through the
cleaner head or the 1” tri clamp connection depending on the mounting position of the Toftejorg
SaniMidget Retractor
