scope:

This European Standard applies to design, manufacturing, installation, transportation, electrical equipment and cleaning of derinding-, skinning-, and membrane removal machines

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.

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

- 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.

- Open skinning- and membrane removal machine with infeed table and a distance between the floor and the surface of the infeed table between 800 mm and 1 050 mm.

Groove form of the transport roller:

Depth < 2,0 mm

Pitch < 2,5 mm

Derinding-, skinning- and membrane removal machines consist mainly of a machine frame, tooth roll with stripper comb, hold down roller with stripper rake, transport roll with stripper roll and air jet cleaning blade device and electrical, electronic, or pneumatic components, depending on the machine type.

Derinding-, skinning- and membrane removal machines can e.g. be equipped with a:

- infeed and outfeed table;

- infeed- and outfeed conveyor belts;

- blade device;

- double blade;

- hold down device, (e.g. hold down rollers, belts or fingers);

- circular knives inside or instead of hold down rollers;

- stripper comb/stripper roll/stripper rake. Derinding-, skinning- and membrane removal machines can be mobile

Intended use

This European Standard deals with all significant hazards, hazardous situations and events relevant to derinding-, skinning- and membrane removal machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

This European Standard deals with the hazards which can arise during commissioning, operation, cleaning, use, maintenance and decommissioning of the machine

The product (raw meat or raw fish) with a weight < 15 kg which is to be processed is either fed by hand or by an infeed device (e.g. infeed conveyor belt) and a hold down device carried to the tooth or transport roller. Using open derinding-, skinning- and membrane removal machines, the product is pressed by hand against the blade device and the rind, the skin or the membrane is cut off by the blade.

Not intended use

A not intended use is e.g.:

- the wrong installation of a derinding-, skinning- and membrane removal machine;

- the processing of flat products on open derinding machines;

- working on open derinding-, skinning- and membrane removal machines without using the gloves which the manufacturer recommends;

- manipulation of interlocking systems on safety devices;

- using of cleaning- and disinfection detergents, which are not recommended by the manufacturer in the instructions for use.
