Principles of design to ensure the cleanability of slicing machines
For the purpose of this annex, the following definitions apply:
The food contact area encompasses all surfaces that come into contact with food, including those that the product may touch during normal use before returning to the product itself.
Area composed of surfaces on which part of the food may splash or flow along under condition of use and does not return into the product
Any area other than those specified above
Designed and constructed to permit the elimination of soil by a simple cleaning method (e.g hand and sponge)
Surfaces are joined so that no particle or product becomes trapped in small crevices, thus becoming difficult to dislodge and so introduce a contamination hazard
Materials of construction shall comply with !5.2 of EN 1672-2:2005"
European Directives outline the materials that can come into contact with food intended for human consumption Certain materials, such as plastics, must undergo overall or specific migration tests Additionally, materials not explicitly listed in these directives may be permitted if their compatibility with food is demonstrated.
Surfaces and parts in the various areas shall meet with the following requirements:
A.3.1.1 The surfaces of any food area shall be smooth and free from pits and scratches
A.3.1.2 Grooves may be used if the inner radius is equal or greater than 4 mm, and depth smaller than 0,7 times the radius
Internal corners must have an angle of 90˚ or greater, with a minimum radius of 3 mm In cases where three planes intersect, at least two of the planes should have a minimum radius of 6 mm.
Joints and seams shall be welded or sealed and shall be as smooth as the surfaces being joined
Machine components that include hooks, spikes, or similar devices for securing products before and after slicing must be designed for easy removal without tools Additionally, these parts should be separable into easily cleanable sections when necessary.
A.3.1.4 Roughness of the surfaces shall be: Rz = 16 àm MAX (see ISO 468)
A.3.2.2 Grooves may be used if the inner radius is equal to or greater than 4 mm, and depth is smaller than one times the radius
Internal corners must have an angle of 60˚ or greater when two planes intersect For angles less than 80˚, a minimum radius of 3 mm is required between the planes In cases where three planes intersect, at least two of the planes should have a minimum radius of 6 mm.
Holes are allowed if they have a minimum diameter of 16 mm and a maximum depth of 16 mm, and they must remain open Additionally, gaps are acceptable as long as they are at least 16 mm wide and do not exceed a depth of 16 mm.
16 mm and the gap is open
Joints and seams must be welded or sealed, with the option to create vertical joints by overlapping metal sheets from the top down to prevent dirt accumulation on horizontal edges The overlap should be a minimum of 12 mm, and non-overlapping joints should be designed for easy separation to facilitate cleaning.
Low profile screws and bolts, as illustrated in figure 17, should be utilized only when alternative fastening methods are not feasible, and they offer the advantage of being easy to clean.
The following types of screws shall not be used:
Hexagon socket head cap screws,
Screws with a diameter less than 3 mm
Parts of the machine, for instance blade sharpener, can have, if necessary, greater grooves, sharper corners and smaller gaps, provided that devices are removable without the use of tools
