Food processing machinery - Dough mixers - Safety and hygiene requirements
This standard specifies safety and hygiene requirements for the design and manufacture of dough mixers with rotating bowls of capacity greater than or equal to 5 l ) and less than or equal to 500 l.
These dough mixers are used to process various ingredients e.g. flour, sugar, fat, salt, water and other ingredients in food manufacturers and shops. These machines are sometimes used in other industries (e.g. pharmaceutical industry, chemical industry, printing), but hazards related to these uses are not considered in this standard.
The following machines are excluded:
- planetary mixers (EN 454);
- continuously fed machines;
- mixers with stationary vertical bowls;
- experimental and testing machines under development by the manufacturer;
- domestic appliances;
- automatic loading and unloading devices.
The intended use of the machine, as defined in 3.12 of EN 292-1:1991 and as given in the manufacturer’s instruction handbook, is the loading of various ingredients, processing them by means of a kneading tool, unloading and cleaning. The operation is usually carried out in cycles of variable duration. Manual operations are sometimes necessary to take samples, to scrape the bowl or add ingredients.
The significant hazards covered by the standard are mechanical (crushing, shearing, trapping, impact and loss of stability), electrical, ergonomic and also those resulting from noise, inhalation of flour dust and lack of hygiene.
This standard does not deal with noise reduction.
It applies only to machines manufactured after the date of issue of this standard.
Nahrungsmittelmaschinen - Teigknetmaschinen - Sicherheits- und Hygieneanforderungen
Diese Europäische Norm behandelt alle signifikanten Gefährdungen, die durch Risikobeurteilung (siehe
EN 1050) ermittelt und in Abschnitt 4 dieser Europäischen Norm aufgeführt werden, die sich bei Zentrifugen
zur Verarbeitung von essbaren Ölen und Fetten ergeben, wenn diese bestimmungsgemäß und unter den vom
Hersteller vorgesehenen Bedingungen verwendet werden.
Sie legt die Sicherheits- und Hygieneanforderungen für die Gestaltung, die Herstellung, den Gebrauch, die
Instandhaltung und die Reinigung von Zentrifugen fest.
Der übliche Betriebsablauf wird in 3.2 beschrieben.
Diese Norm gilt nicht für Maschinen, bei denen Extraktion durch Lösungsmittel erfolgt und
Zusatzeinrichtungen (z.B. Förderbänder, Trichter usw.) zum Einsatz kommen.
Sie gilt nicht für Korbzentrifugen.
Diese Norm gilt in erster Linie für Maschinen, die nach dem Datum der Annahme durch CEN hergestellt
werden.
Machines pour les produits alimentaires - Pétrins - Prescriptions relatives à la sécurité et l'hygiène
La présente norme européenne spécifie les prescriptions de sécurité et d'hygiène relatives à la conception et à la
construction des pétrins de boulangerie et de pâtisserie à cuve tournante d'un volume supérieur ou égal à 5 l 1)
et inférieur ou égal à 500 l.
Ces pétrins sont utilisés pour travailler différents ingrédients comme la farine, le sucre, les matières grasses, le sel,
l'eau, etc. dans l'industrie alimentaire et les commerces de l'alimentation. Ces machines sont parfois utilisées
dans d'autres industries (par exemple : industrie pharmaceutique, chimique, imprimerie) mais les risques relatifs
à ces utilisations ne sont pas pris en compte dans cette norme.
Les machines suivantes sont exclues :
- les batteurs-mélangeurs (EN 454) ;
- les machines travaillant en alimentation continue ;
- les mélangeurs à cuve verticale fixe ;
- les machines expérimentales ou d'essais en cours de mise au point par le fabricant ;
- les appareils domestiques ;
- les appareils automatiques de chargement et de déchargement.
L'utilisation normale d'une machine, telle que définie en 3.12 de l'EN 292-1:1991 et dans le manuel d'instructions
du fabricant, comprend les opérations de chargement des divers ingrédients, le travail de ceux-ci à l'aide de l'outil
de pétrissage, le déchargement et le nettoyage. Le fonctionnement s'effectue généralement par cycles de durée
variable. Des opérations manuelles sont quelquefois nécessaires pour prélever des échantillons, racler la cuve ou
ajouter des ingrédients.
Les phénomènes dangereux significatifs couverts par la norme sont mécaniques (écrasement, cisaillement,
entraînement, choc et perte de stabilité), électriques, ergonomiques et aussi ceux résultant du bruit, de l'inhalation
de poussière de farine et du manque d'hygiène.

Stroji za predelavo hrane - Mešalniki testa - Varnostne in higienske zahteve
Ta standard določa varnostne in higienske zahteve za načrtovanje in izdelavo mešalnikov testa z vrtečimi se skledami prostornine, večje ali enake 5 ter manjše ali enake 500 l. Ti mešalniki testa se uporabljajo za obdelavo raznih sestavin, t.j. moke, sladkorja, maščobe, soli, vode in ostalih sestavin za proizvajalce živil in trgovin. Te stroje se včasih uporablja tudi v drugih industrijah (t.j. farmacevtski industriji, kemični industriji, tiskanje), vendar nevarnosti, povezane s tovrstno uporabo, v tem standardu niso upoštevane. Izvzeti so naslednji stroji: - planetarni mešalniki (EN 454); - stroji z neprekinjenim podajanjem; - mešalniki s stalnimi navpičnimi posodami; - eksperimentalni in preskusni stroji v razvoju z strani proizvajalca; - gospodinjski aparati; - naprave z samodejnim nakladanjem in razkladanjem. Predvidena uporaba stroja, kot je določeno v 3.12 EN 292-1:1991 in podano v proizvajalčevem priročniku z navodili, je nakladanje raznih sestavin, obdelava le-teh z orodjem za gnetenje, razkladanje in čiščenje. Postopek se običajno izvaja v ciklih z različnim trajanjem. Včasih je za odvzem vzorcev, postrganje posode ali dodajanje sestavin potrebno ročno posredovanje. Velike nevarnosti, zajete z tem standardom, so mehanske (zdrobitev, ureznine, ujetje, udarci in izguba stabilnosti), električne, ergonomske in prav tako tiste, ki so posledica hrupa, vdihavanja prahu moke in pomanjkanja higiene. Velja samo za stroje, izdelane po datumu objave tega standarda.

4.2 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). 4.3 Hazards generated by noise Especially large dough 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. 4.4 Hazards resulting from inhalation of dust Use of dough mixers 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. 4.5 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. 4.6 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.

5.1.1.2 In order to facilitate dough discharge from dough mixers with non-removable bowls,
movement of the kneading tool and bowl motions at low speed is permitted with the guard opened, by operation of a hold-to-run control. This allows the operator to turn the bowl for unloading the bowl in different positions. 5.1.1.3 Stopping time Guard actuated stopping devices shall stop the dough mixer with the bowl empty within 4 s of opening the guard.

If the mass of the filled removable bowl exceeds 25 kg, a handling device shall be fitted, for example wheels on the bowl or a separate trolley. Pushing and pulling with excessive effort shall be avoided e.g. by use of low -friction castor wheels or by the design of the bowl coupling mechanism. If tilting of the bowl is manual, it shall require a force not more than 250 N. When lowering of the kneading tool is manual, lowering or lifting with the bowl empty shall require a force not more than 250 N in normal operating conditions.
