Foreword
This European Standard (EN 13591:2005) has been prepared by Technical Committee CEN/TC 153 “Food
processing machinery — Safety and hygiene specifications”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by April 2006, and conflicting national standards shall be withdrawn at the
latest by April 2006.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association and supports essential requirements of EC Directive(s).
For relationship with EC Directives, see informative Annex ZA, which is an integral part of this document.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
This European Standard is a type C standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for machines
that have been designed and built according to the provisions of this type C standard.
1 Scope
This European Standard applies to the design and manufacture of fixed deck oven loaders used in the food
industry, bakeries, pastry-making, etc. These machines are used to place dough pieces on each deck of fixed
deck ovens and to remove the baked products from each deck.
This equipment may be:
 manual;
 semi-automatic (some movements powered, some movements requiring manual power).
The European Standard covers technical safety and hygiene requirements for the design, installation,
adjustment, operating, cleaning and maintenance of this equipment.
This European Standard deals with the significant hazards, hazardous situations and events relevant to fixed
oven deck loaders, when used as intended and under the conditions foreseen by the manufacturer.
Noise from fixed deck oven loaders is not considered to be a significant hazard. That does not mean that the
manufacturer of the machine is absolved from reducing noise and making a noise declaration. Therefore a
noise test code is given in Annex A.
The following equipment are excluded:
 experimental equipment and equipment under development by the manufacturer;
 loaders for conveyor ovens;
 loaders integral to the oven;
 fully automated fixed deck oven loaders.
This European Standard in not applicable to fixed deck oven loaders that are manufactured before the date of
publication of this European Standard by CEN.

3 Description
3.1 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN ISO 12100-1:2003 and the
following apply.
NOTE Shifting, lifting, and loading in the oven are the three main functions of a fixed deck oven loader.
3.1.1
shifting
movement of the whole oven loader to the oven face
3.1.2
lifting
vertical movement up and down
3.1.3
loading
action of placing pieces of dough on the oven loader
3.1.4
loading in the oven
action of introducing and placing pieces of dough on the decks of the oven
3.1.5
unloading
action of removing loaves from the oven deck once baking has finished
3.1.6
nominal mass of dough
the mass the loader is intended for
3.2 General principle
A fixed deck oven loader generally consists of a frame mounted on castors supporting a lifting device and a
supporting platform with the loading device (see Figure 1).
The frame is mounted on castors to enable the loader to be positioned in front of the oven for loading and
unloading.
The lifting device (e. g. scissors lifting mechanism, lifting mast,…) allows the height of the oven loader to be
varied for loading and unloading at different levels in the oven.
The loading device comprises a frame and a belt in order to place the pieces of dough in the oven and to take
out the loaves when baking has finished.
