Stroji za predelavo hrane - Planetarni mešalniki - Varnostne in higienske zahteve
Ta standard določa varnostne in higienske zahteve za načrtovanje in izdelavo planetarnih mešalnikov z nepremičnimi posodami z orodjem s planetarnim gibanjem. Prostornina posode je večja ali enaka 5 l in manjša ali enaka 200 l.
Ti stroji se uporabljajo za predelavo različnih sestavin, npr. kakava, moke, sladkorja, olj in maščob, mletega mesa, jajc in drugih sestavin pri kateringu, v pekarnah, picerijah, pri izdelavi testa in v industriji slaščic.
Ti stroji se včasih uporabljajo v drugih industrijah (npr. v farmaciji, kemijski industriji, tiskarstvu itd.), vendar nevarnosti, povezane s temi uporabami, niso obravnavane v tem standardu.
Obdelava se izvaja v različno dolgih ciklih. Nadzorovana je lahko ročno ali avtomatsko, v posameznih ciklih ali s ponavljajočimi cikli itd. Včasih je potrebno ročno dodajanje sestavin brez ustavljanja stepalnika.
Pri strojih, ki so opremljeni napravo za dviganje in spuščanje posode ali napravo za premikanje posode/glave/stepalnika navpično v delovnem položaju, je to takrat, ko je stepalnik najbližje dnu posode.
Ta evropski standard opisuje vsa večja tveganja, nevarne situacije in nevarne dogodke v zvezi s planetarnimi mešalniki, kadar se uporabljajo v skladu z njihovim namenom in pod pogoji pričakovane nepravilne uporabe, ki jih določa proizvajalec. Obravnava nevarnosti zaradi uporabe, vzdrževanja in čiščenja.
Ta evropski standard ne obravnava naslednjih strojev:
– nastavkov za katering za planetarne mešalnike (glej EN 12851);
– strojev z nenehnim podajanjem;
– mešalnikov testa (glej EN 453);
– poskusnih in preskusnih strojev, ki jih razvijajo proizvajalci;
– gospodinjskih aparatov.
Ta dokument se ne uporablja za stroje, ki so bili izdelani pred datumom objave dokumenta kot evropskega standarda.

Key 1 casing 2 control devices 3 bowl 4 tool 5 auxiliary drive hub 6 handle 7 trolley 8 interlocked guard (solid cover) Figure 1 — Main parts of a planetary mixer 3.3 Classification Planetary mixers are classified into the following two categories according to their bowl volume: — class 1: bowls having a volume equal to or greater than 5 L and less than 10 L; — class 2: bowls having a volume equal to or greater than 10 L and less than or equal to 200 L, where the bowl volume is the maximum volume of water in litres that the bowl can contain. When a mixer is supplied with several bowls of different capacities, the mixer classification is determined by the size of the bowl with the greatest volume. 4 List of significant hazards This clause contains all the significant hazards, hazardous situations and events, identified by risk assessment as significant for this type of machinery and which require measures to eliminate or reduce the risk associated with the identified hazards (see Table 1). SIST EN 454:2015
Key zone 1: volume covered by the moving tool zone 2: auxiliary drive hub for attachments zone 3: space between bowl lifting system and frame Figure 2 — Danger zones of a planetary mixer (with guard removed) 5 Safety and hygiene requirements and/or protective measures 5.1 General Machinery shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards, which are not dealt with by this document. Unless otherwise specified, the requirements given throughout Clause 5 apply both to Class 1 and Class 2. 5.2 Mechanical hazards 5.2.1 General Where reference is made to interlocking devices throughout Clause 5, they shall comply with EN ISO 14119. The safety related parts of the control system shall present at least a performance level “c” defined in accordance with EN ISO 13849-1. SIST EN 454:2015
Figure 3 — Class 1 planetary mixers with bowl extension For class 2 planetary mixers, preventing access to the tool may be achieved by a movable interlocking guard covering the top of the bowl. In working position the distance between the upper edge of the interlocked guard and the machine frame shall be less than or equal to 80 mm. If the interlocked guard is solid (e.g. a cover without apertures), it can also be used to prevent flour dust emission hazard (see 5.9), and the following requirements apply. The interlocked guard shall be linked to suitable actuated position detectors functioning in the positive mode in compliance with EN ISO 14119:2013, 5.4. Position detectors themselves shall comply with EN ISO 14119:2013, 5.2 and 5.3.1, and any rotary or linear cams with EN ISO 14119:2013, 5.3.2. SIST EN 454:2015
The opening space between the bowl and the movable guard (see Figure 4a) and Figure 4b)) shall be less than or equal to 8 mm in the working position. The distance between the rear edge of the protective device and the nearest point of the machine (see Figure 4a) and Figure 4b)) shall be less than or equal to 15 mm in the working position. The opening space between the upper edge of the bowl and lower edge of the interlocked guard shall be less than or equal to 25 mm when the interlocking device is actuated (see Figure 4c) and Figure 4d)). The opening space between the edge of the interlocked guard and the frame of the machine shall be less than or equal to 25 mm when the interlocking device is actuated (see Figure 4). SIST EN 454:2015

The opening can be enlarged by combining several openings which are separated by bars where the dimensions of each opening comply with the values of Table 3. SIST EN 454:2015

5.2.2.2 Mixers with several bowls Where a mixer is supplied with several bowls, the requirements of 5.2.2.1 or 5.2.2.2 shall be met for the largest bowl, as applicable. In the working position, the opening space Z shall be less than or equal to 15 mm for each bowl supplied with the mixer (see Figure 6). SIST EN 454:2015
Key 1 largest bowl 2 smallest bowl Z space opening between upper edge of the bowl and lower edge of the guard Figure 6 — Mixer with several bowls 5.2.2.3 Access to the tool The tool drive mechanism shall not be capable of operation when the bowl is not in place and in the working position e.g. by a switch actuated by a cam located inside the frame. 5.2.2.4 Stopping time Guard actuated stopping devices shall stop the tool 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 tool has stopped moving. This can be achieved by providing an interlocking guard with guard locking (see EN ISO 12100:2010, 3.27.5). 5.2.3 Zone 2 – Auxiliary drive hub (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. 5.2.4 Zone 3 – Space between bowl lifting system and frame 5.2.4.1 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. 5.2.4.2 When manually operated 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. 5.2.4.3 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 pressure-sensitive edge or; — a hold-to-run control to operate the bowl movement. SIST EN 454:2015
