BS EN 1678:1998+A1:2010EN 1678:1998+A1:2010 (E) 4 Introduction The use of vegetable cutting machines involves various mechanical and other hazards
22、. Their extensive use justifies the need of a standard covering both safety and the hazards to food hygiene arising from machine design. !This European Standard is a type C standard as stated in EN ISO 12100. The machinery concerned and the extend to which hazards, hazardous situations and events ar
23、e covered are indicated in the scope of this European Standard. 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 d
24、esigned and built according to the provisions of this type C standard.“ 1 Scope ! 1.1 This European Standard specifies the safety and hygiene requirements for the design and manufacture of vegetable cutting machines which are transportable and have a maximum rated power less than 3 kW. This European
25、 Standard deals with machines intended for cutting, shredding, dicing, chipping and grating of food products in which the product passes through the machine. As described in 3.2.1, the types of machines in the scope are machines with a fixed chamber and rotating blade or cutting disc, with a rotatin
26、g drum and fixed blades or machines with horizontal reciprocating cutters (mainly used for potato chipping). 1.2 This European Standard specifies all significant hazards, hazardous situations and events relevant to vegetable cutting machines, when they are used as intended and under conditions of mi
27、suse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard deals with the hazards which can arise during commissioning, operation, cleaning, removal of food blockages, feeding, changing the tools, maintenance and decommissioning of the machine. 1.3 This European
28、 Standard does not apply to: food processors (see EN 12852); vegetable peelers (see EN 13208); vegetable cutting attachments which are mounted onto machines having an auxiliary drive hub (see EN 12851); planetary mixers (see EN 454); domestic machines. 1.4 This European Standard is not applicable to
29、 vegetable cutting machines which are manufactured before the date of its publication as EN.“ BS EN 1678:1998+A1:2010EN 1678:1998+A1:2010 (E) 5 2 !Normative references The following referenced documents are indispensable for the application of this document.

37、erms and definitions For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and the following apply. BS EN 1678:1998+A1:2010EN 1678:1998+A1:2010 (E) 6 3.1.1 pusher device device assisting feeding, hinged to the hopper and interlocked so when withdrawn from the hopp
38、er the machine stops. It prevents access to the danger zone when in the working position 3.1.2 plunger device device assisting feeding, which is removable“ 3.2 Description 3.2.1 Machines covered by the standard This standard covers the three following types of machine including combinations of them:
39、 3.2.1.1 Machines with rotating cutting devices Such machines contain the rotating cutting devices in a fixed chamber. Product is fed into the top of the chamber, typically through a feed hopper and assisted by a pusher or plunger device (see figure 1). Key 1 Body 2 Electric motor 3 Delivery chute 4

As the product is held
41、 against the outside wall by the spinning drum so it comes into contact with a fixed cutting device (see figure 2). Key 1 Body 2 Motor 3 Delivery chute 4 Cutting device 5 Shaft 6 Rotating drum 7 Fixed grid 8 Feed hopper Figure 2 3.2.1.3 Machines with horizontal reciprocating cutters These machines a
42、re used extensively for chipping potatoes. Raw potatoes are fed from a hopper into the cutting chamber containing fixed plates and reciprocating plates and cutting devices (see figure 3).

43、ers 5 Fixed plate 6 Reciprocating plate 7 Baffles Figure 3 3.2.2 Elements of a machine (see figures 1, 2 and 3) All machines generally contain the following elements of design: a device for feeding product into the machine; one or several tools: cutting plates or blades, hereafter called “cutting de
44、vices“. A cutting plate or blade consists of one or more cutting edges fixed to a frame. Fixed cutting blades may be installed in conjunction with moving plates; an ejector; a delivery chute; control devices. 3.2.3 Devices for feeding Three devices for feeding product are used: 3.2.3.1 Hopper feed T
45、he product is fed to the cutter from the hopper generally by gravity and/or by feeding devices. BS EN 1678:1998+A1:2010EN 1678:1998+A1:2010 (E) 9 3.2.3.2 Pusher feed Here a small amount of product is fed into a feed chute and assisted to the cutters by pressure on the pusher device. 3.2.3.3 Plunger
46、feed Here product is manually fed to the cutting device. It is assisted with a plunger. Typically the feeding is done through a narrow feed chute. Often machines have both pusher and plunger feed so that the operator can select the most suitable operation according to the food product being cut. 4 !
47、List of significant hazards 4.1 General This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this European Standard, identified by risk assessment as significant for this type of machinery, and which require action to eliminate or reduce
48、 the risk.“ 4.2 Mechanical hazards 4.2.1 Access to the danger zones Mechanical hazards arise from the risk of contact with the cutting devices and the associated rotating parts. The hazards may be reached by: Zone 1: access down the feed chute/hopper; Hazard of cutting and drawing-in, Zone 2: access when opening the machine to expose the cutter or drum. Typically this is when cleaning the machine or changing the cutting device. Hazard of cutting and drawing-in; Zone 3: access through the delivery chute; Hazard of crushing and drawing-in; Zone 4: access
