SSD BREAKDOWN SERVICE

Should your SSD Natural Casing Cleaning machine break down, please contact SSD directly and a service engineer will be sent out to repair the machine/s.

SSD SERVICE AND PLANNED MAINTENANCE

SSD can arrange an annual full service to check the machine/s over, service oil, grease and replace any worn parts. Preventative maintenance or scheduled servicing is the best way to ensure reliability or product, processing and optimum casing quality.

CLEANING CASING MACHINES

In the interest of hygiene and cleanliness at the end of each working shift the machine/s and equipment must be thoroughly cleaned. Generally speaking, the rollers are self-cleaning and will be relatively clean if the machine is allowed to run for five minutes after the last runner has passed through, with the spray pipe left in the ‘on’ position. After the machine/s have been switched off, isolate the machines from the electrical supply before attempting to clean the equipment.

The machines should then be washed with a mild detergent and a soft brush: care should be taken to ensure that no finished product is present in the tanks or in the vicinity of the machine/s before the detergent is applied.

The residual soap or detergent should be flushed away with warm water at a maximum temperature of 55 degrees Celsius. The inside of the roller guards is cleaned in the same manner.
It will be necessary to occasionally remove all of the fixed guards and remove and residual contamination that has accumulated in areas that cannot be washed with a hose. The frequency at which the machines are stripped down for cleaning will be determined to suit individual operations.

Note: DO NOT use high pressure hoses or steam to clean the equipment; this will cause severe roller damage. Only use low pressure warm water on the rollers.

CARE OF STAINLESS STEELS

Stainless steels are iron alloys with a minimum of 10.5% chromium. The corrosion resistance of Stainless steel arises from a “passive”, chromium rich oxide film that forms naturally on the surface of steel.
The film is strongly adherent and chemically stable under conditions which provide sufficient oxygen on the surface.
The key to durability of the corrosion resistance of stainless steel is that if the film is damaged it will normally repair itself which is in stark contrast to other steels which have been electroplated or have a similar finish.

Note: Stainless steels cannot be considered indestructible as the passive state can, under certain conditions, be broken down and corrosion will result.

CLEANING STAINLESS STEELS

Wash with mild detergent and warm water. Localised rust stains caused by carbon steel contamination may be removed by using an abrasive rubbing block or by using a propriety gel or 01% phosphoric acid solution, followed by ammonia and water rinses or oxalic acid solution followed by water rinses.

Note: Health & safety precautions must be observed when handling chemicals and COSHH rules followed.

AVOIDING CONTAMINATION AND RUSTING

Avoid all contact with carbon steels. Knives etc. left resting on machine surfaces and the grinding etc. of mild steels withing the vicinity of stainless steels is an extremely bad practice. Grinding dust, invisible to the naked eye, lying on the surface of stainless steel when wet, not only represents a health hazard to the consumer of your product but will cause rusting, pitting and eventually holes. Keep surfaces clean. Do not allow any materials liable to form a skin to remain on stainless steel surfaces.

Note: Corrosion problems can be caused by contamination with mild steel and when microscopic particles of sulfur rich impurities present on the surface of the metal as a result of uneven cooling during manufacture which tend to have less chromium around them.

LUBRICATION

SSD machinery must receive adequate lubrication in order to ensure a long, trouble-free service life and quality of product.
At the end of each working shift and after the line has been cleaned apply one shot of good quality high melting point grease to the drive shaft lubrication nipples.
Do note if you have specifically sealed for life gearboxes, these require no attention.

Note: DO NOT lubricate the machine whilst it is running. Isolate form the electrical supply before lubricating.
