1.1This 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.

1.2This 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)
