Food processing machinery - Automatic industrial slicing machines - Safety and hygiene requirements

1.1 General
This European standard specifies requirements relating to the design and construction of mainly not moveable slicing machines and auxiliary components.
The slicing machines covered by this standard are used for the cutting and portioning of meat and sausage products, cheese or other sliceable food products that can be cut using one or more blades. Slicing machines are designed to cut pieces or slices.
A sickle blade or an eccentrically moving blade is used for cutting. As a rule, the product only moves along one axis during the cutting process.
The auxiliary components covered by this standard are used for conveying products from the cutting zone, for weighing or for sorting the cut portions.
The specific hazards associated with separate auxiliary components which are used for automatically supplying the meat product and for forming and preparing the portions are not covered in this standard. These auxiliary components shall comply with the requirements in accordance with EN ISO 12100:2010 where relevant.
This European standard covers all the significant hazards, hazardous situations and hazardous events identified by means of risk assessment associated with automatic slicing machines and auxiliary components if they are used in accordance with regulations and under the conditions of foreseeable misuse defined by the manufacturer (see Clause 4).
This standard covers hazards which may arise during the commissioning, operation, cleaning, servicing and decommissioning of the machine.
This standard only applies to automatic slicing machines and auxiliary components that were manufactured after the date of publication of this standard.
This standard applies to automatic slicing machines and auxiliary components designed for industrial use. These are machines which are usually used in food processing facilities. The machines are normally permanently installed in one place.
This standard does not apply to cutting machines with moving infeed slides, slicing machines that are used in for example shops, restaurants, supermarkets, canteens etc. and are already covered in EN 1974.
This standard does not apply to portion cutting machines which are manufactured and put on the market in accordance with the requirements specified in EN 13870.

Stroji za predelavo hrane - Avtomatski industrijski stroji za rezanje na rezine - Varnostne in higienske zahteve

1.1 Splošno
Ta evropski standard podaja zahteve, povezane z načrtovanjem in gradnjo predvsem nepremičnih strojev za rezanje na rezine ter pomožnih sestavnih delov.
Stroji za rezanje na rezine, ki jih zajema ta standard, se uporabljajo za rezanje in razdeljevanje mesnih izdelkov in klobas, sira ter drugih prehrambnih izdelkov, ki jih je mogoče rezati na rezine z enim ali več rezili. Stroji za rezanje na rezine so zasnovani za rezanje kosov ali rezin.
Za rezanje se uporablja srpasto rezilo ali ekscentrično premikajoče se rezilo. Praviloma se med postopkom rezanja izdelek premika samo po eni osi.
Pomožni sestavni deli, ki jih zajema ta standard, se uporabljajo za odvajanje izdelkov z območja rezanja, tehtanje ali razvrščanje rezin.
Posebne nevarnosti, povezane z ločenimi pomožnimi sestavnimi deli, ki se uporabljajo za samodejno dovajanje mesnega izdelka ter za oblikovanje in pripravo porcij, niso zajete v tem standardu. Ti pomožni sestavni deli morajo ustrezati zahtevam standarda EN ISO 12100:2010, če je to ustrezno.
Ta evropski standard zajema vse bistvene nevarnosti, nevarne okoliščine in nevarne dogodke, identificirane z oceno tveganj, povezanih z avtomatskimi stroji za rezanje na rezine ter pomožnimi sestavnimi deli, če se ti uporabljajo, v skladu s predpisi in pogoji predvidljive napačne uporabe, ki jo je opredelil proizvajalec (glej točko 4).
Ta standard zajema nevarnosti, do katerih lahko pride pri usposabljanju za zagon, obratovanju, čiščenju, servisiranju in izločitvi stroja iz uporabe.
Ta standard se uporablja samo za avtomatske stroje za rezanje na rezine in pomožne sestavne dele, ki so bili proizvedeni po datumu objave tega standarda.
Ta standard se uporablja za avtomatske stroje za rezanje na rezine in pomožne sestavne dele, ki so bili zasnovani za industrijsko uporabo. To so stroji, ki se običajno uporabljajo v obratih za predelavo hrane. Stroji so običajno trajno nameščeni na enem mestu.
Ta standard se ne uporablja za stroje za rezanje s premičnimi podajalnimi drsniki, stroje za rezanje na rezine, ki se uporabljajo na primer v trgovinah, restavracijah, supermarketih, menzah ipd. in jih že zajema standard EN 1974.
Ta standard se ne uporablja za stroje za rezanje na rezine, ki so bili proizvedeni in dani na trg v skladu z zahtevami standarda EN 13870.
1.2 Opis stroja
Ta standard zajema naslednje zasnove (glej slike od 1 do 7):
Različice zasnove glede na območje podajanja:
– stroj za rezanje na rezine z ročnim podajanjem
– stroj za rezanje na rezine s samodejnim podajanjem
– stroj za rezanje na rezine z neprekinjenim podajanjem
Različice zasnove glede na izhodno območje:
