1.1 This European 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 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 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. This standard only applies to machines which are manufactured after the date of issue of this standard. 1.2 This standard covers the 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 < 5,0 mm Pitch < 6,5 mm (see Figures 1 and 2) Key 1 2 3 4 5 Tooth roll/ Transport roll Blade Discharge table Blade holder Infeed table 6 7 8 9 10 ON/OFF Switch, cover Foot switch Drive Locking device Table height Key 1 2 3 Round product Cutting thickness < 5 mm Infeed table 4 5 6 7 8 Tooth roll Blade holder Blade Rind Stripper comb Figure 1 - Derinding-, skinning- and membrane Figure 2 - System of an open derinding machine removal machine - Automatic derinding machine with infeed, hold down, and outfeed device and a distance between the floor and the surface of the infeed device, e.g. conveyor belt between 800 mm and 1 050 mm. Tooth form of the tooth roll: Depth < 5,0 mm Pitch < 12,0 mm Hold down roller diameter 175 mm to 240 mm. (see Figures 3 and 4)
