3.1.2
planetary movement
rotation of a tool both on itself and around the inside of a bowl by using two parallel axes
3.1.3
working position
stable position both for the bowl and the tool and in which the bowl is locked in the upper position and the tool. locked on its shaft, is nearest to the bottom of the inside of the bowl
3.2 Description
A planetary mixer (see Figure 1) usually consists of a frame supporting:
— a casing (1), containing the tool(s) drive mechanism:
— control devices (2);
— a bowl (3) equipped with a grid or a solid cover, in which ingredients are processed;
— interchangeable tool (4) designed to process ingredients: their rotation speed may be either constant or variable;
— an optional auxiliary drive hub (5)for catering attachments (see EN 12851);
— a device (6) for vertically moving the bowl or the head of the mixer to allow tool removal, or tilting of the head to remove the tool;
— a device (7) for handling the bowl (optional), for example a trolley;
— an interlocked guard (8);
— bowl heating device (optional, not included in Figure 1);
— bowl cooling device (optional, not included In Figure 1);
— bowl gravity discharge (optional, not included in Figure 1).
5.2.5.3 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 5.2.5.2.
5.3 Electrical hazards
5.3.1 General
Electrical equipment — for example switches — that may be exposed to water, e.g. during cleaning, shall be
protected to an appropriate IP-rating according to EN 60529 and EN 60204-1.
The electrical equipment shall comply with EN 60204-1, with the following requirements given in 5.3.2, 5.3.3.
5.3.4 and 5.3.5.
5.3.2 Safety requirements related to electromagnetic phenomena
The machines shall have sufficient immunity to electromagnetic disturbances to enable them to operate safely as intended and not fail to danger when exposed to the levels and types of disturbances for the intended use of the machine (see EN 61000-6-1).
The manufacturer of the machines shall design, install and wire the equipment and sub-assemblies taking into account the recommendations of the suppliers of these sub-assemblies.
5.3.3 Protection against electnc shock
The electrical equipment shall comply with EN 60204-1:2006. Clause 6.
5.3.4 Power circuits
Devices for detection and interruption of over-current shall be applied to each live conductor in compliance with EN 60204-1:2006, 7.2.3. In case of single phase machines, no such device Is required for the earthed neutral conductor.
5.3.5 Protection against earth faults in control circuits
For machinery supplied from a single-phase conductor and an earthed neutral conductor the single pole
interruption shall be in the phase conductor (see EN 60204-1:2006, 9.4.3.1).
5.4 Motor enclosures
Where a motor has a degree of protection lower than 1P23 it shall be mounted inside an enclosure (see EN 60204-1:2006. 14.2) that guarantees a minimum degree of protection of 1P23.EN 454-2014 pdf download.
