Resumen:

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

The machines described in this standard are used for derinding-, skinning- and membrane removal of meat and fish by cutting at a straight blade and/or cutting with circular blades. Feeding could be done manually or automatically.

Using open derinding-, skinning- and membrane removal machines, the product is guided by hand towards the cutting device.

With automatic derinding-, skinning and membrane removal machines the product is transported by an infeed conveyor against the cutting device. Product with a weight > 25 kg has to be processed by an automatic machine.

Derinding-, skinning-, and membrane removal machines for domestic purposes, hand-guided machines and table-top machines are not covered by this standard.

This document only applies to machines which are manufactured after the date of issue of this document.

This document covers the following types of machines:

  1. open derinding machines (see Figure 1 and Figure 2) with infeed table and a distance h between the standing position and the surface of the infeed table from 800 mm to 1 050 mm. The cutting thickness shall be t = 5 mm;

  2. open skinning- and membrane removal machines (see Figure 1 and Figure 3) with infeed table and a distance h between the standing position and the surface of the infeed table from 800 mm to 1 050 mm. The cutting thickness shall be t = 0,5 mm.

  1. Automatic machines (see Figure 4 and Figure 5), which are charged by an operator, with a distance between the standing position and the surface of the infeed conveyor between 800 mm and 1 050 mm.

    Automatic machines which are charged automatically and are integrated in dismantling lines do not have to follow the requirements on the height of the surface of the infeed conveyor (800 mm to 1 050 mm) because the ergonomic matters need not be considered.

    Automatic machines could be equipped with different rolls (see Figure 6).

  1. Combining machines are designed to be used as automatic or open machines.

Derinding-, skinning- and membrane removal machines consist mainly of a machine frame, tooth roller with stripper comb, hold-down roller with stripper rake, transport roller with stripper roller, cutting 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 / or outfeed table;

  • infeed and / or outfeed conveyor;

  • cutting device;

  • rolls (e.g. see Figure 6);

  • stripper comb/stripper roller/stripper rake.
