23、GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 12355:2003 (E) 4 Introduction This European Standard relates to: derinding machines with tooth roll, hold down roller and blade device; skinning- and membrane removal machines with transport- and stripper roll as well as a blade device. 1 Scope 1.1This E
24、uropean Standard applies to design, manufacturing, installation, transportation, electrical equipment and cleaning of derinding-, skinning-, and membrane removal machines (see Figures 1 to 5). The machines described in this standard are used for derinding-, skinning- and membrane removal of meat and
25、 fish by cutting at a blade device. Derinding-, skinning-, and membrane removal machines for domestic purposes and table-top machines are not covered by this standard. This standard only applies to machines which are manufactured after the date of issue of this standard. 1.2This standard covers the
26、following types of machines: Open derinding machines with infeed table and a distance between the floor and the surface of the infeed table from 800 mm to 1 050 mm. Tooth form of the tooth roll: Depth 800 mm. 5.2.1.1.4 The operation switch for the drive system of the tooth roll shall be a hold-to-ru
27、n control. The tooth roll shall stop within 2 s, after the operator has released the operating switch (see 5.3.1). The operating switch can, for example, be foot, knee or belly operated and shall be protected against unintentional actuation. 5.2.1.1.5 Normal positioning of machines The access to ope
28、n derinding machines shall be prevented, except the operator side. This will be achieved e.g. by the following measures: normal positioning of a machine in a small working area An open derinding machine shall be positioned with one side towards a wall. The table and a container shall be placed on th
29、e other free sides to receive the round products (see Figures 10 and paragraph 7.1a). The operator stands in front of the open derinding machine. By this way of positioning access to the open derinding machine is prevented for other persons. normal machine positioning in working area with cutting li
30、ne An open derinding machine shall be positioned with one side against the cutting line. The table and a container will be placed on the other free sides in order to receive the round products (see Figure 11 and paragraph 7.1a). The operator stands in front of the open derinding machine. By this way
31、 of positioning access to the open derinding machine is prevented for other persons.

Flat products (e.g. fatbacks) shall only be used in conjunction with
35、 automatic derinding machines (see 5.2.2). 5.2.1.1.8 Wearing of protective gloves When operating an open derinding machine, the operator shall only wear manufacturer approved protective gloves. Metal wire mesh gloves, or metal wire reinforced gloves shall not be worn (see 7.1.d). On open derinding m
36、achines a permanently fixed notification shall be present, with the following text: “Attention: Do not wear metal wire mesh gloves or metal wire reinforced gloves”. 5.2.1.1.9 Operator training The manufacturer shall devise safe working procedures to be followed by operators. These shall be included
37、in the instructions for use (see 5.2.1.1.10), together with the elements of training and frequency of retraining to be given to the operators.5.2.1.1.10 Information in the instruction handbook. 5.2.1.1.10 The manufacturer shall in the instruction handbook describe clearly: processing of tall, round
38、products ( 5.2.1.1.3); the normal positioning of machines in small working areas ( 5.2.1.1.5, paragraph 1); the normal machine positioning in working areas with cutting line (5.2.1.1.5, paragraph 2); further possibility of machine positioning (5.2.1.1.6); normal operating conditions on open derindin

This can be achieved e.g. by observance of the following measures: 5.2.1.2.1The angle between tooth roll and stripper comb shall be 90 (see Figure 13). 5.2.1.2.2 The stripper comb shall be interlocked.
