1.1 This document specifies requirements for design, performance, safety and hygiene of refrigerated bulk milk coolers and the related methods of test.

NOTE The informative Annex J gives some elements regarding the estimation and calculation of energy consumption.

This document deals with all significant hazards, hazardous situations and events relevant to bulk milk coolers on farm, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

It applies to refrigerated bulk milk tanks with air-cooled condensing units and automatic control intended for installation on farms or at milk collection points. It applies to tanks for two milkings (24 h), four milkings (48 h) and six milkings (72 h), in which the cooling takes place totally (non-pre-cooled milk) or partially (in case of pre-cooled milk) within the tank. It also applies to tanks in combination with a continuous system of milking (e.g. milking with robot).

1.2 This document does not cover:

— mobile tanks;

— tanks intended to be tilted for drainage;

— equipment for delivering the milk to the tank;

— equipment for pre-cooling of the milk;

— the hazards due to the use of other energy than electrical energy;

— pressure aspect of vacuum tanks (i.e. tanks where the inner part of the vessel is designed to operate at a pressure below atmospheric pressure).

1.3 Noise is not considered to be a significant hazard, but relevant for bulk milk coolers. This document therefore includes information in 7.1 and in Annex A concerning the manufacturer's declaration of the noise emission level of the cooler.

1.4 This document does not cover the calibration requirements for the tank to be used as a system for payment purpose.

1.5 This document is not applicable to bulk milk coolers on farm which are manufactured before the date of its publication as EN.

This document specifies safety and hygiene requirements of clipping machines (hereafter referred to as machine) for closing of casings filled with foodstuffs (hereafter referred to as product) by using a clip, and which are intended to be used in butcheries, meat processing factories, main kitchens and other food processing factories.

Clipping machines are used to close tubes with a single clip (one side) or a double clip (end locking and start locking).

The machines are equipped with closing tools (punch/die), which create the closure by deforming the locking element (clip).

This document deals with all significant hazards, hazardous situations and hazardous events relevant to machinery when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

This document covers the following types of machines:

— semi-automatic machine (see Figure 1 and Figure 2);

— automatic machine (see Figure 3).

This document does not cover any machines whose closing procedure is only performed manually.

This document is not applicable to machinery manufactured before the date of publication of this document by CEN.

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:

a) 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;

b) 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.

 

c) 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).

 

 

d) 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.
