Introduction
The extent to which hazards are covered is indicated in the scope of this standard. In addition, machinery
shall comply as appropriate with EN 292 for hazards which are not covered by this standard.
1 Scope
This standard specifies safety and hygiene requirements for the design and manufacture of fixed bowl
1)
planetary mixers of capacity greater than or equal to 5 l and less than 500 l used to process various
ingredients e.g. cocoa, flour, sugar, oils and fat, minced meat, eggs, and other ingredients, in the food
industry and shops.
These machines are sometimes used in other industries (e.g. pharmaceutical industry, chemical industry,
printing, etc.), but hazards related to these uses are not considered in this standard.
The following machines are excluded:
 accessory planetary mixers;
 continuously fed machines;
2)
 dough mixers ;
 experimental and testing machines under development by the manufacturers;
 domestic appliances.
The intended use of the machine, as defined in 3.12 of EN 292-1:1991 and in the manufacturer's instruction
handbook, is loading various ingredients, processing them in a stationary bowl by means of appropriate
beaters, unloading and cleaning.
Processing is carried out in cycles of variable duration.
It can be either manually or automatically-controlled, in individual cycles or on a cycle repeat basis, etc.
Manual operations are sometimes necessary to add ingredients without stopping the beater.
On machines fitted with a bowl lifting and lowering device or with a device for moving the bowl/head/beater
vertically the working position is that when the beater is nearest to the bottom of the bowl.
The significant hazards covered by this standard are mechanical (shearing, trapping, loss of stability),
electrical, thermal, ergonomic and also hazards resulting from gas accumulation, noise, inhalation of dust, and
lack of hygiene.

3 Description
A planetary mixer (see figure 1) usually consists of a frame supporting:
a) a casing containing the beater(s) drive mechanism;
b) control devices;
c) a bowl, in which ingredients are processed;
d) interchangeable beaters designed to process ingredients and which move around a fixed or mobile axis
(planetary motion). Their rotation speed may be either constant or variable;
e) a power connection for attachments such as meat mincers, vegetable slicers, etc.;
f) a device for vertically moving the bowl or the head of the mixer to allow beater removal;
g) a device for handling the bowl, for example a trolley.
The following features may also be included:
 bowl heating;
 bowl cooling;
 bowl gravity discharge.
Figure 1 a)      Figure 1 b)
Figure 1 — Main parts of a planetary mixer (with guard removed) and illustration of bowl diameter
4 Classification
Planetary mixers shall be divided into the following three categories according to their bowl volume and/or
diameter:
 class 1 shall have a volume equal to or greater than 5 l and less than 10 l and/or a diameter less than or
equal to 260 mm;
 class 2 shall have a volume equal to or greater than 10 l and less than 150 l and/or a diameter greater
than 260 mm and less than or equal to 510 mm;
 class 3 shall have a volume greater than or equal to 150 l and less than 500 l and/or a diameter greater
than 510 mm;
Where:
 the bowl volume is the maximum volume of water in litres that the bowl can contain;
 the bowl diameter is the inside diameter D measured at the bowl upper edge (figure 1).
When a mixer is supplied with several bowls of different capacities, the mixer classification shall be
determined by the size of the bowl with the greatest volume.
5 List of hazards
This clause contains all hazards identified by risk assessment (see EN 1050) as specific and significant for
planetary mixers and which require action to reduce risk.
!When fixed guards, or parts of the machine acting as such, are not permanently fixed e.g. by welding, their
fixing systems shall remain attached to the guards or to the machinery when the guards are removed."
5.1 Mechanical hazards
The significant mechanical hazards are:
 shearing hazard;
 trapping hazard;
 loss of stability.
The example shown in figure 2 illustrates 3 danger zones associated with these hazards:
zone 1:volume covered by the moving beater; hazard of trapping;
zone 2:mechanical power connection for attachments, if any; hazard of shearing, trapping;
zone 3:space between bowl lifting system and frame; hazard of trapping during bowl lifting/lowering.

Figure 2 — Danger zones of a planetary mixer (with guard removed)
5.2 Electrical hazards
Hazard of electric shock from direct or indirect contact with live components.
Hazard of external influences on electrical equipment (e.g. cleaning with water).
5.3 Thermal hazards
Where a bowl heating device is fitted, there is a hazard of burns by contact with the heating device or with the
bowl.
5.4 Hazards generated by gas accumulation
Where open flame heating devices are used as bowl heating, there is a hazard of gas accumulation.
5.5 Hazards generated by noise
Especially class 3 planetary mixers generate airborne noise which can result in hearing damage, in accidents
due to interference with speech communication and interference with the perception of acoustic signals.
5.6 Hazards resulting from inhalation of dust
Because of the larger volume of ingredients processed, the use of class 3 planetary mixers particularly
exposes operators to dust including flour and ingredients which may be harmful to their health, causing rhinitis
(running noses), watering eyes and possibly occupational asthma.
5.7 Lack of hygiene
Lack of hygiene can create a risk to human health and unacceptable modification of foodstuff e.g.
contamination by microbial growth or foreign materials.
5.8 Hazards generated by neglecting ergonomic principles
During operation, cleaning and maintenance, there is a risk of injury or chronic damage to the body resulting
from awkward body postures.
Movement of the bowl between different working stations, or filling or emptying of the bowl can create a risk of
injury or chronic damage to the body from lifting, pushing and pulling of heavy loads.
6 Safety and hygiene requirements and/or measures
This clause states the requirements and/or measures to be met to reduce the effect of the hazards detailed in
clause 5.
6.1 Mechanical hazards
Where reference is made to interlocking devices throughout clause 6, they shall comply with clauses 4.2.1, 5
and 6 of EN 1088:1995.
Safety related control systems shall be category 1 as defined in clause 6 of EN 954-1:1996.
6.1.1 Zone 1 - Volume covered by the movement of the beater
6.1.1.1 Class 1 planetary mixers
Because of their low power and small size, access to the volume covered by the beater need not be
prevented but shall be at least restricted in the following ways:
a) there shall be a minimum distance of 120 mm between the upper edge of the bowl and the upper limit of
the volume covered by the beater (see figure 3 a));
b) a bowl extension shall be provided. This may be fixed or associated with an interlocking device and
movable so that the beater will not operate unless it is in position (see figure 3 b)).

Figure 3 — Class 1 planetary mixers

6.1.1.2 Class 2 planetary mixers
A class 2 planetary mixer shall be fitted either with a guard as specified in 6.1.1.3 or with one or more
sensitive bars complying with the following:
 the bars shall stop the beater rotation when a vertical upward or downward force of 30 N is applied to
them;
 movement to actuate the stopping device shall not exceed 5 mm;
 there shall be a minimum distance of 120 mm between the upper limit of the volume covered by the
beater and the upper edge of the bowl;
 the distances between the trip bar (or bars), the bowl and the machine frame shall comply with the values
shown in figure 4;
 the design of the trip bar shall minimize the risk that the accumulation of food between the trip bar and a

6.1.1.5 Up and down movement
On class 2 and class 3 machines an interlocking device shall prevent beater movement when the bowl lifting
system is not in the normal operating position e.g. a switch actuated by a cam located inside the frame.
However, if it is necessary to process ingredients in anything other than the normal bowl position, the beater
control shall be of the hold-to-run type (see 3.23.3 of EN 292-1:1991).
The hold-to-run control shall be located following ergonomic principles of EN 614-1:1995 taking account of
hygienic requirements (see 6.6).
6.1.1.6 Stopping time
Guard actuated stopping devices shall stop the beater without any ingredients present in the bowl in less than
or equal to 4 s. If this not possible, opening of the guard shall be prevented until the beater has stopped
moving (see 3.22.5 of EN 292-1:1991).
When a sensitive bar is used, the stopping devices shall stop the beater with the bowl empty in less than or
equal to 2 s.
6.1.2 Zone 2 - Power connection (mechanical)
The drive shaft on which attachments are fitted shall not project from the machine frame and shall be fitted
with a cover which cannot be removed from the machine, e.g. hinged, so as to enclose the connection point.
6.1.3 Zone 3 - Space between bowl lifting system and frame
6.1.3.1 The guide and drive mechanism operating the vertical movement of the bowl shall not create any
risks of trapping or pinching. This may be achieved by use of a fixed guard.
6.1.3.2 When manually operated the minimum distance between either the bowl or the frame and the lever
for lifting and lowering the bowl shall be 50 mm in order to prevent injury when operating the lever.
6.1.3.3 If the bowl lifting and lowering mechanism is motorized, crushing between the ascending bowl, bowl
lifting system and machine frame and any guard shall be prevented. This may be by either:
- a trip device or;
- a hold-to-run control to operate the bowl movement.
6.1.3.4 For class 2 and class 3 machines, the bowl lifting and lowering mechanism shall be able to hold a
vertical force equal to twice the weight of the bowl filled with water, when it is in its upper position.
6.1.4 Loss of stability
Machines shall be designed to be stable and shall comply with 6.1.4.1 to 6.1.4.2 as applicable.
For machines to be fixed to the floor, the instruction handbook shall indicate the values of forces at the fixing
points.
6.1.4.1 Free standing machines without castors shall be stable when tilted 10° from the horizontal plane in
the most unfavourable direction.
6.1.4.2 Free standing machines with castors shall have at least two castors (or sets of castors) fitted with a
locking device, and shall comply with the provisions of 6.1.4.1.
6.2 Electrical hazards
The electrical equipment shall comply with EN 60204-1:1997, with the following precisions.
6.2.1 Electromagnetic compatibility (see 4.4.2 of EN 60204-1:1997)
Where electrical/electronic components are used, the manufacturer shall ensure that the equipment shall not
generate electromagnetic disturbances above the levels that are appropriate for its intended place of use. In
addition, the equipment shall have adequate level of immunity to electromagnetic disturbances so that it can
correctly function in its intended place of use.
NOTE 1 The supplier of the electrical/electronic equipment should be able to detail its electromagnetic compatibility.
NOTE 2 Where conditions of use, installation and maintenance are specified by the supplier in order to achieve
electromagnetic compatibility, these should be complied with by the manufacturer.
6.2.2 Cleaning with water
If it is intended that the machine be cleaned with water, the manufacturer shall provide warnings and a method
of cleaning in the instruction handbook.
6.2.3 Protection against electric shock (see clause 6 of EN 60204-1:1997)
The electrical equipment shall comply with clause 6 of EN 60204-1:1997.
6.2.4 Power circuits (see 7.2.3 of EN 60204-1:1997)
A device for detection and interruption of overcurrent in the phase conductor is sufficient for single phase
machines.
6.2.5 Earth faults (see 9.4.3.1 of EN 60204-1:1997)
For machinery supplied from a single phase conductor and an earthed neutral conductor, there is no
requirement for double pole interruption.
6.2.6 Emergency stop (see 10.7 of EN 60204-1:1997)
An emergency stop is not required.
6.2.7 Motor enclosures (see 15.2 of EN 60204-1:1997)
Where a motor has a degree of protection lower than IP23 it shall be mounted inside an enclosure that
guarantees a minimum degree of protection of IP23.
6.3 Thermal hazards
On machines equipped with a device to maintain food at a constant temperature during processing, bowl
handles and grips shall be designed in such a way as to avoid burns according to EN 563:1994.
6.4 Gas accumulation hazard
Open flame heating devices shall be allowed only on class 1 and class 2 machines. Means shall be provided
to prevent escape of unburnt gas e.g. a flame protection system. Further details of gas burner control systems
can be found in EN 298.
6.5 Noise reduction
Planetary mixers shall be so designed and constructed that risks from airborne noise emission are reduced to
the lowest level by particularly applying measures at source to control noise (see for example
EN ISO 11688-1). The success of the applied noise reduction measures is assessed on the basis of the actual
noise emission values (see and Annex C) in relation to other machines of the same family.
6.6 Dust hazard
Flour dust emission shall be minimised.
Particularly for a class 3 planetary mixer, this may be achieved by any of the methods in the following
examples:
a) use of a solid cover;
b) by means of a time-delay device which, when starting the machine, makes the tool rotate at no more than
60 rpm for the planetary action and 180 rpm for the tool for a least 120 s before the operator can engage
a higher speed;
c) by means of a dust extraction device;
If the machine is intended for use with automatic feeding of dry ingredients, the manufacturer shall design
measures to prevent dust emission during feeding without decreasing the level of safety.
NOTE 1 This standard does not deal with automatic feeding.
NOTE 2 In the future revision of the standard, more information will be given relating to the prevention of dust
emission. A research program is being carried out on this subject.
A method for measuring dust is given for information in annex B.
6.7 Hygiene requirements
Planetary mixers shall be designed and manufactured in accordance with EN 1672-2:1997 and annex A.
The 3 zones shown in figure 7 are defined in EN 1672-2:1997. The precise boundary between the zones
depends on the detailed design of the machine but in general they are at least as follows.
6.7.1 Food area
The food area is as follows:
 the inside of the bowl;
 the beater and rotating holder of the beater;
 the inside of solid bowl guards or the whole of guards with holes;
 any trip bars.
6.7.2 Splash area
The splash area is as follows:
 the outside of the bowl;
 for solid guards, the outside surface of the guard;
 the front surface of the machine facing the bowl;
 the horizontal surface above the bowl.
6.7.3 Non food area

Annex A
(normative)
Principles of design to ensure the cleanability of planetary mixers
A.1 Definitions
For the purpose of this annex, the following definitions apply.
A.1.1 easily cleanable
Designed and constructed to permit the elimination of soil by a simple cleaning method (e.g. hand and
sponge).
A.1.2 fitted surfaces
Surfaces separated by a distance less than or equal to 0,5 mm.
A.1.3 joined surfaces
Surfaces between which no particle of product becomes trapped in small crevices, thus becoming difficult to
dislodge and so introduce a contamination hazard.
A.2 Materials of construction
A.2.1 Type of materials
A.2.1.1 Materials for food area:
Some materials (e.g. plastics) shall be the subject to overall or specific migration tests.
NOTE European Directives give the list of materials in contact with food and foods intended for human consumption.
Materials not mentioned in the European Directives are accepted as long as food compatibility is proven.
A.2.1.2 Materials for splash area
See 5.2.2 in EN 1672-2:1997.
A.2.1.3 Non food area
See 5.2.3 in EN 1672-2:1997.
A.2.2 Surface conditions
The surface finish of materials used on surfaces shall permit easy cleaning under satisfactory conditions. The
roughness values (R ) according to ISO 468 shall comply with the values given in tables A.1 and A.2.

A.3 Design
A.3.1 Connections of internal surfaces
Connections shall have the same roughness as the connected surfaces. These shall be designed to avoid any
dead space, see EN 1672-2:1997.
A.3.1.1 Connections of internal surfaces for food area
Two surfaces shall be connected according to:
 rounded edge having a radius greater than a curve of minimum radius (r ) of 3 mm obtained by:
 machining (cutting into material mass);
 bending the sheet metal (bending and forming);
 design (in moulds, shells of foundry, injection
