Abstract

The procedure consists of a cleaning stage, an ultrasound renovation stage in which the utensils are immersed in a vessel linked to an ultrasound generator, an air drying stage and a packaging stage. The place settings are packed in individual sachets and sterilized or rendered aseptic, and all the stages are carried out in a laboratory or specially arranged plants

Description

La présente invention concerne un procédé pour nettoyer,rénover, raviver, lustrer les couverts de table en acier inoxydable des restaurants traditionnels et de collec tivité, les emballer en film individuel et les aseptiser ou stériliser dans un laboratoire ou atelier d'hygiène et de traitement des couverts spécialement équipé à cet effet. The present invention relates to a method for cleaning, renovating, reviving, buffing stainless steel tableware in traditional and community restaurants, wrapping them in individual film and sanitizing or sterilizing them in a laboratory or workshop for hygiene and treatment cutlery specially equipped for this purpose.

Traditionnellement les couverts de table en acier inoxydable, tels que les couteaux, les fourchettes, les petites et grandes cuillers sont lavés et séchés dans des machines à laver la vaisselle pour restaurants de collecti vité. Cependant suite à cette opération il reste sur les couverts des petites traces de calcaire, des auréoles ou salissures, ce qui nécessite un nettoyage manuel de ces ustensibles pris un à un, à l'aide d'un torchon imbibé d'une solution d'eau et de vinaigre blanc. Traditionally, stainless steel tableware, such as knives, forks, small and large spoons are washed and dried in dishwashers for community restaurants. However, following this operation, there are small traces of limescale, stains or dirt on the cutlery, which requires manual cleaning of these utensils, taken one by one, using a cloth soaked in a solution of water and white vinegar.

Le procédé propose une succession d'étapes de traite ment d'hygiène des couverts de table en acier inoxydable comportant premièrement un nettoyage et un ravivage des couverts en les immergeant dans une cuve remplie d'eau et d'un liquide spécial; cette cuve étant reliée à un générateur à ultrasons, les couverts pouvant être mis en léger mouvement afin d'éliminer toutes les traces de calcaire et de salissure après la phase de lavage et séchage en lave-vaisselle. Le générateur d'ondes à ultrasons peut être immergé dans la cuve principale. La dimension de la cuve permet l'immersion de plusieurs milliers de couverts appartenant à différents restau rants traditionnels ou de collectivité, immergés de préférence à la verticale et groupés par lots dans des paniers permettant de les différencier selon l'appartenance des clients. The method proposes a succession of hygienic treatment steps for stainless steel tableware, comprising firstly cleaning and reviving the cutlery by immersing it in a tank filled with water and a special liquid; this tank being connected to an ultrasonic generator, the cutlery can be put in slight movement in order to remove all traces of lime and dirt after the washing and drying phase in the dishwasher. The ultrasonic wave generator can be submerged in the main tank. The size of the tank allows the immersion of several thousand cutlery belonging to different traditional or collective restaurants, preferably submerged vertically and grouped in batches in baskets making it possible to differentiate them according to the customers' belonging.

Après immersion dans la cuve à ultrasons, les couverts de table en acier inoxydable sont rincés dans une autre cuve remplie d'eau déminéralisée et enfin retirés pour être séchés par un système d'air chaud en milieu fermé pour éviter les salissures au contact de l'air ambiant. Le laboratoire est équipé pour traiter environ 100<B>000</B> couverts par jour. After immersion in the ultrasonic tank, the stainless steel tableware is rinsed in another tank filled with demineralized water and finally removed to be dried by a hot air system in a closed environment to avoid soiling on contact with water. 'ambiant air. The laboratory is equipped to treat around 100 <B> 000 </B> covers per day.

Après séchage, les couverts -sont emballés en sachet individuel de polypropylène ou polyéthylène par une machine d'emballage formant les sachets à partir d'une bobine ou d'un emballage de papier poreux ou tout autre type d'emballage à usage médical. La machine d'emballage est d'un type tradition nellement utilisé pour l'emballage en sachet individuel et peut être munie de machine rotative pour améliorer la produc tivité. After drying, the cutlery is wrapped in an individual polypropylene or polyethylene sachet by a packaging machine forming the sachets from a reel or a packaging of porous paper or any other type of packaging for medical use. The packaging machine is of a type traditionally used for packaging in individual sachets and can be fitted with a rotary machine to improve productivity.

Les couverts sont enfin rassemblés à nouveau dans des boitiers ou paniers et placés à l'intérieur, soit d'un autoclave, soit d'un four poupinel en vue d'y être stérilisés par chaleur humide ou chaleur sèche. Cette opération de stérilisation terminant le cycle de traitement des couverts.The cutlery is finally reassembled in boxes or baskets and placed inside, either in an autoclave or in a baby oven in order to be sterilized by humid heat or dry heat. This sterilization operation ends the cutlery treatment cycle.

L'aseptisation ou stérilisation peut également advenir par l'émission de rayonnement ultraviolet ou par un rayonnement gamma. Asepticization or sterilization can also occur by the emission of ultraviolet radiation or by gamma radiation.
