EN 13621:2004+A1:2010 (E) 5 Introduction The use of salad dryers involves various mechanical and other hazards. !Their extensive use in numerous countries justifies the need of a standard covering both safety and the hazards to food hygiene." !This European Standard is a type C standard as stated in EN ISO 12100." 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 1.1 This document specifies the safety and hygiene requirements for the design and manufacture of salad dryers taking account of installation, cleaning, removal of jammed food, feeding, maintenance and decommissioning. The spinning function is obtained by the rotation of a perforated basket in which the product being processed is placed. It applies to machines:  which are intended for use in the commercial and institutional catering industry;  having a rotation speed between 300 rpm and 900 rpm;  having a nominal output below 2 kW;  having a nominal volume of the basket less than 100 l. These machines can be stationary or movable. The machines concerned by this document are those appliances which are intended for eliminating by spinning the water present on salad after washing. These machines can also be used for spinning other vegetables such as spinach, watercress, radish, French beans, etc. The machines covered by this document are not intended to be cleaned with water jet. !This European Standard deals with all significant hazards, hazardous situations and events relevant to salad dryers, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4)." NOTE If the machine is not used under above conditions, the manufacturer should verify, when he is informed of such situation, if the preventive measures remain valid (see 3.22 of EN ISO 12100-1:2003). The feeding principle of the machine can be notably:  manual loading into the basket left in position in the machine;  placing in and withdrawal from the machine of the loaded basket. 1.2 Noise is not considered to be a significant hazard with salad dryers. This does not mean that the manufacturer of these machines is absolved from reducing noise and making a noise declaration. Therefore a noise test code is proposed in Annex A. 1.3 Vibrations are not considered as a hazard with these machines. 1.4 This document is not applicable to the machines which are manufactured before the date of publication of this document by CEN. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

NOTE See also EN 1672-2 which deals with hygiene risks to the operator. 4.5 Hazards generated by neglecting ergonomic principles in machine design Lack of applying ergonomic principles can be anything that causes wrong operation of controls, physical damage due to over-reaching, heavy loads, awkward posture, etc. 5 Safety and hygiene requirements and/or measures 5.1 General Salad dryers shall comply with the safety requirements and/or protective measures of this Clause. In addition, they shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant, which are not dealt with by this document (e.g. sharp edges). !NOTE For hazards which are to be reduced by the application of another standard such as EN 1672-2, EN 60204-1 and EN ISO 13857, the manufacturer should carry out a risk assessment to establish the requirements of that standard which are to be applied. This specific risk assessment is part of general risk assessment of the salad dryer." !When fixed guards, or parts of the machine acting as such, are not permanently fixed e.g. by welding, their fixing systems shall remain attached to the guards or to the machine when the guards are removed." Where the means of reducing the risk is by the physical arrangement or positioning of the installed dryer the manufacturer shall include in the information for use a reference to the reduction means to be provided, and to any limiting value of the requirement, and, if appropriate, to the means of verification. SIST EN 13621:2004+A1:2010



EN 13621:2004+A1:2010 (E) 11 Where the means of reducing the risk is by a safe system of working the dryer, the manufacturer shall include in the information for use details of the system and of the elements of training required by the operating personnel. 5.2 Mechanical hazards 5.2.1 General For the machines covered by this document, the safety shall be in the first place intrinsically ensured by the design, the shape and the choice of materials, according to the requirements given below. 5.2.2 Access to the danger zones 5.2.2.1 Machines of class 1 5.2.2.1.1 Zone 1: basket The inside and outside of the basket shall not present any sharp parts, roughness or raised parts likely to create a hazard of impact or abrasion. If the impact or abrasion hazards is not withdrawn by design, the rotating basket shall disconnect itself immediately, as soon as its rotation becomes blocked, e.g. by using a frictional drive. 5.2.2.1.2 Zone 2: space between the tank and the basket In any case the space between the tank and the basket shall be less than 8 mm or greater than 20 mm. 5.2.2.1.3 Zone 3: basket drive device By design, the drive device shall not present any sharp parts, nor create impact or entanglement. 5.2.2.1.4 Zone 4: rotation generating device Access to the danger zone shall be prevented by fixed guards complying with EN 953. 5.2.2.1.5 Zone 5: access to the rotation zone of the basket through the water evacuation device The spinning water evacuation device shall be designed in such a manner that the introduction of a finger or of the hand into the pipe opening does not cause any jamming of the operator's fingers between the basket and the bottom of the tank (Table 4 of !EN ISO 13857:2008" shall apply). In addition, this device shall be unable to be dismantled without the use of tools. 5.2.2.1.6 Zone 6: space between the tank and the cover The cover shall be stable in full opening position (e.g. at least 10° over the limit of stability). 5.2.2.2 Machines of class 2 The requirements of 5.2.2.1.1 to 5.2.2.1.6 apply with the following additional requirements for zones 1, 2 and 3. These machines shall have a stopping time less than 4 s or be equipped with an interlocked cover with guard locking. !All the interlocking devices associated with guards shall comply with EN 1088. The parts of the control system related to the interlocking shall meet at least category 1 of 6.2.2 of
EN 954-1:1996 or present at least a performance level c defined in accordance with
