Den foreliggende opfindelse angår en fremgangsmåde til maskinopvask, især en forbedring af kontinuerlig eller ikke-kontinuerlig maskinopvask, uanset om der anvendes en maskine med ét eller flere kar eller en maskine med transportbånd.The present invention relates to a method of machine washing, in particular an improvement of continuous or non-continuous machine washing, whether one or more vessels or a conveyor belt machine is used.
5 Ved en typisk fremgangsmåde til maskinopvask bliver service eller køkkengrej såsom tallerkener eller fade, der er tilsmudset med madrester, bakker, bestik og glas med læbestiftpletter sprøjtet kraftigt med vand i et forvaskeområde eller en forvaskecyklus. Det vand, der anvendes til forvasken, kan enten være koldt eller foropvarmet rent vand eller kølevand fra en dampkondenseringsproces, men er 10 normalt overløbsvand fra en vaskevæske, der som regel sprøjtes på genstandene ved relativt lavt tryk og i relativt stor mængde fra hensigtsmæssigt placerede sprøjtedyser. Efter dette forvaskeområde eller denne forvaskecyklus indføres genstandene i selve vaskeområdet eller udsættes for vaskecyklen, hvor de igen sprøjtes kraftigt, denne gang med en vaskevæske.5 In a typical machine dishwashing procedure, service or kitchen utensils such as dishes or dishes that are soiled with food scraps, trays, cutlery and glasses with lipstick stains are heavily sprayed with water in a pre-wash area or pre-wash cycle. The water used for the prewash can be either cold or preheated pure water or cooling water from a vapor condensation process, but is usually overflow water from a wash liquid which is usually sprayed onto the articles at relatively low pressure and in a relatively large amount from appropriately located spray nozzles. . After this pre-wash area or pre-wash cycle, the items are introduced into the wash area itself or subjected to the wash cycle where they are again heavily sprayed, this time with a wash liquid.

Vaskevæsken er sædvanligvis vand med en temperatur på fra 50 til 60°C, hvortil et flydende eller pulverformigt detergent er blevet tilsat. For at fjernelse af fedt, stivelse, pletter og protein skal være tilstrækkelig pålidelig tilsættes vandet fx pulverformigt eller flydende detergent indtil en mængde på 0,1-0,3 vægtprocent 20 aktivt rensemiddel i opløsning. Den resulterende vaskevæske sprøjtes på genstandene ved hjælp af en pumpe igennem nedre og øvre dyser og i visse tilfælde gennem yderligere sidedyser. Smudset på genstandene fjernes eller i det mindste kvælder eller blødgøres og til dels opløses af vaskevæsken. I efterfølgende skyile-områder eller -cykler fjernes de kvældede eller blødgjorte madrester, og samtidig 25 bortskylles vaskevæsken med vand. I et afsluttende skylleområde eller skylle-cycklus fjernes eventuelle rester af vaskevæsken med vand med en temperatur på op til ca. 85°C. Det vand, der anvendes til den endelige skylning, består af rent vand tilsat et skyllemiddel, der sikrer, at der på genstandene kun resterer en ul-tratynd vandhinde, der kan fordampe i et efterfølgende tørreområde.The wash liquid is usually water at a temperature of from 50 to 60 ° C to which a liquid or powder detergent has been added. For the removal of fat, starch, stains and protein to be sufficiently reliable, for example, the water is added powdered or liquid detergent to an amount of 0.1-0.3% by weight of 20 active detergent in solution. The resulting washing liquid is sprayed onto the articles by means of a pump through lower and upper nozzles and in some cases through additional side nozzles. The dirt on the objects is removed or at least swelled or softened and dissolved in part by the washing liquid. In subsequent shelter areas or cycles, the swollen or softened food residues are removed and at the same time the wash liquid is rinsed with water. In a final rinse area or rinse cycle, any residue of the wash liquid with water with a temperature of up to approx. 85 ° C. The water used for the final rinsing consists of pure water added with a rinse aid which ensures that only an ultra-thin water membrane can evaporate in the subsequent drying area.

Anvendelsen af selv relativt store mængder detergent til regelmæssig konventionel opvask vil ikke altid fjerne behovet for periodisk kraftig rengøring. Formålet med denne yderligere rengøring er at fjerne belægninger af fx vanduopløselige pletter eller stivelse, der gradvis er blevet opbygget, men som ikke umiddelbart er 35 synlige. Til denne kraftige rengøring behandles genstandene lejlighedsvis med en vaskevæske indeholdende flere gange den normale mængde detergent. En forud gående manuel ibiødlægning kan eventuelt anvendes til samme formål. Begge disse metoder medfører yderligere forurening af spildevandet.The use of even relatively large quantities of detergent for regular conventional washing will not always eliminate the need for periodic vigorous cleaning. The purpose of this further cleaning is to remove coatings of, for example, water-insoluble stains or starches which have been gradually built up but which are not immediately visible. For this vigorous cleaning, the items are occasionally treated with a washing liquid containing several times the normal amount of detergent. A prior manual embedding may optionally be used for the same purpose. Both of these methods cause further pollution of the wastewater.
DK 171583 B2 2 5 GB-A-1.099.701 omhandler en fremgangsmåde til rengøring af en overflade, hvor et væskeformigt medium omfattende en detergent i en koncentration på mindst 0.5%, og i hvilket der er suspenderet i det væsentlige vand-uigennemtrængelige, ikke-slibende inerte partikler, sprøjtes på overfladen. Der er ingen antydning i dette dokument, at detergentopløsninger alene vil kunne anvendes til rengøring af 10 overflader.GB-A-1,099,701 discloses a method of cleaning a surface wherein a liquid medium comprising a detergent at a concentration of at least 0.5% and in which substantially water-impermeable, non-impermeable, is suspended. - abrasive inert particles, sprayed onto the surface. There is no suggestion in this document that detergent solutions can only be used for cleaning 10 surfaces.
Et formål med den foreliggende opfindelse er tilvejebringelse af en overraskende fordelagtig opvaskemetode. Den forbedrede rengøringseffektivitet, der opnås, kan reducere forbruget af arbejdskraft, vand og kemikalier, hvilket nedsætter for-15 urening og antal omvaskninger, mens den sikrer tilfredsstillende rengøring selv under vanskelige forhold.An object of the present invention is to provide a surprisingly advantageous washing method. The improved cleaning efficiency achieved can reduce the consumption of labor, water and chemicals, reducing pollution and the number of washings while ensuring satisfactory cleaning even in difficult conditions.
Ved den foreliggende opfindelse tilvejebringes en fremgangsmåde til maskin-opvask, hvilken fremgangsmåde er ejendommelig ved, at et højkoncentreret van-20 digt opvaskepræparat indeholdende mindst 0,5 vægtprocent af ét eller flere aktive rengøringsmidler påsprøjtes i det mindste delvis tilsmudsede genstande, og at opvaskepræparatet og smuds efter en kontaktperiode på mindst 2 sekunder fjernes i ét eller flere efterfølgende trin.The present invention provides a method for machine washing which is characterized in that a highly concentrated aqueous detergent containing at least 0.5% by weight of one or more active detergents is sprayed onto at least partially soiled articles, and dirt after a contact period of at least 2 seconds is removed in one or more subsequent steps.
25 En opvaskemaskine kan indrettes til at udøve en sådan fremgangsmåde, fx ved tilføjelse af yderligere sprøjtedyser og dermed forbundne systemer og/eller ved ændringer i maskinens styresystemer.A dishwasher can be arranged to practice such a method, for example by adding additional spray nozzles and associated systems and / or by changing the machine's control systems.
Det vandige opvaskepræparat kan fremstilles på basis af pulverformige eller fly-30 dende materialer. Ifølge opfindelsen indeholder det pisprøjtede rengøringspræparat mindst 0,5 vægtprocent af ét eller flere aktive rengøringsmidler. Mens fx 30 vægtprocent kunne betragtes som en øvre grænse, er den kritiske faktor den, at præparatet skal forblive sprøjtbart. Det udsprøjtede opvaskepræparat indeholder fortrinsvis fra 0,8 til 10 vægtprocent, især fra 0,9 til 3 vægtprocent af ét eller flere 35 aktive rengøringsmidler.The aqueous dishwashing composition can be made from powdered or liquid materials. According to the invention, the piss-sprayed cleaning composition contains at least 0.5% by weight of one or more active detergents. For example, while 30% by weight could be considered an upper limit, the critical factor is that the preparation must remain sprayable. The extruded dishwashing composition preferably contains from 0.8 to 10% by weight, in particular from 0.9 to 3% by weight of one or more active detergents.
DK 171583 B2 3DK 171583 B2 3
Ifølge opfindelsen vil en kontaktperiode på mindst 2 sekunder være tilstrækkelig til den ønskede kemiske, i modsætning til mekaniske, virkning. Ved foretrukne udførelsesformer kan kontaktperioden være på fra 5 til 100 sekunder, især fra 8 5 til 25 sekunder. For at tilvejebringe den ønskede, forlængede, intime kontakt eller "mætning" bliver sprøjtningens "mekaniske virkning" i det mindste minimeret, selv om den eventuelt ikke helt undgås. I denne kontaktperiode bliver genstandene, der er under opvask, ikke udsat for tilsigtet sprøjtning.According to the invention, a contact period of at least 2 seconds will be sufficient for the desired chemical, as opposed to mechanical, effect. In preferred embodiments, the contact period can be from 5 to 100 seconds, especially from 8 to 25 seconds. In order to provide the desired, extended, intimate contact or "saturation", the "mechanical effect" of the spraying is at least minimized, although it may not be completely avoided. During this contact period, the objects that are being washed are not subjected to intentional spraying.
10 For at opnå optimale resultater er det vigtigt, at i det væsentlige hele overfladen af en tilsmudset genstand kommer i kontakt med det udsprøjtede opvaskepræparat, og mængden af udsprøjtet præparat samt måden, hvorpå det udsprøjtes, kan tilpasses dette formål. En findelt, blid, tågelignende spray er specielt ønskværdig. I en maskine med transportbånd spiller båndets fremføringshastighed og-15 så en rolle. Især udvælges det udsprøjtede volumen og/eller antallet og/eller placeringen af sprøjtedyser således, at lavvolumen- og lavintensitetssprøjtning vil sikre den ønskede type af fuldstændig dækning og jævn fordeling. Arten, volumenet og koncentrationen af det udsprøjtede præparat kan varieres, ligesom udsprøjtningsorganerne kan varieres afhængigt af fx transportbåndets belastning 20 og, hvor det er relevant, dets bevægelse og/eller fremføringshastighed. Den i nærværende beskrivelse omtalte tågelignende påføring af koncentreret opvaskepræparat med lille volumen/lav intensitet står i kontrast til den kraftige højvolu-mensprøjtning, der anvendes ved konventionel maskinopvask.In order to obtain optimum results, it is important that substantially the entire surface of a soiled object comes into contact with the sprayed dishwasher and the amount of the sprayed as well as the manner in which it is sprayed can be adapted to this purpose. A finely divided, gentle, fog-like spray is especially desirable. In a conveyor belt machine, the conveyor speed of the belt also plays a role. In particular, the spray volume and / or the number and / or location of spray nozzles are selected so that low volume and low intensity spraying will ensure the desired type of complete coverage and even distribution. The nature, volume and concentration of the sprayed composition may be varied, as may the sprayer means, depending, for example, on the conveyor belt load 20 and, where appropriate, its movement and / or feed rate. The fog-like application of low volume / low intensity concentrated dishwashing composition described herein contrasts with the powerful high volume spraying used in conventional machine washing.
25 I almindelighed kan en fremgangsmåde til maskinopvask eventuelt omfatte én eller flere forvaskecykler eller -områder, fx til fjernelse af kraftig tilsmudsning, et eller flere vaskeområder og et eller flere skylleområder. Ifølge den foreliggende opfindelse påsprøjtes den usædvanligt højkoncentrerede rengøringsopløsning ved et trin inden den endelige skylning, ofte som i det mindste en del af en vaskecyk-30 lus eller i et vaskeområde.In general, a method of machine washing may optionally comprise one or more prewash cycles or areas, for example, for the removal of heavy soiling, one or more washing areas and one or more rinsing areas. According to the present invention, the unusually highly concentrated cleaning solution is sprayed at one step prior to final rinsing, often as at least part of a wash cycle or in a wash area.
Mens alle de nødvendige rengøringsmidler kan inkorporeres i det påsprøjtede koncentrat, kan det være fordelagtigt at tilføre yderligere opvaskepræparat på konventionel måde i løbet af processen. Sædvanligvis er dette yderligere materiale 35 ikke det samme som det påsprøjtede koncentrat, men det kan dog være det 4 DK 171583 B2 samme præparat, som blot er yderligere fortyndet. Især er anvendelsen af et komplementært præparat anbefalelsesværdigt. Balancen mellem de komplementære produkter kan også justeres. Fx kunne en højalkalisk spray balanceres af en efterfølgende mindre alkalisk vask. Det foreliggende system tillader også, at der 5 anvendes kemikalier, som normalt ville være inkompatible, hvis de var blandet sammen i et enkelt produkt til anvendelse i hinandens nærværelse; fx kan oxidationsmidler såsom hypochlorit anvendes i sprayen, mens vandkonditionerende midler såsom NTA (nitrilotriacetat) tilføres senere.While all the necessary detergents can be incorporated into the sprayed concentrate, it may be advantageous to add additional detergent in a conventional manner during the process. Usually this additional material 35 is not the same as the sprayed concentrate, but it may be the same composition which is merely further diluted. In particular, the use of a complementary preparation is recommended. The balance of the complementary products can also be adjusted. For example, a highly alkaline spray could be balanced by a subsequent less alkaline wash. The present system also allows the use of chemicals which would normally be incompatible if mixed together in a single product for use in each other's presence; for example, oxidizing agents such as hypochlorite can be used in the spray, while water-conditioning agents such as NTA (nitrilotriacetate) are added later.
10 Selv om det koncentrerede opvaskepræparat som regel påsprøjtes mere eller mindre vedvarende under den pågældende del af opvaskeprocessen, kan det anvendes med mellemrum eller lejlighedsvis, fx i vaskecyklen i en maskine uden transportbånd.10 Although the concentrated dishwashing agent is usually sprayed more or less continuously during that part of the dishwashing process, it can be used periodically or occasionally, for example, in the washing cycle of a machine without a conveyor belt.
15 Det påsprøjtede vandige opvaskepræparat skal kunne flyde, men kan fx være i form af en opløsning, en emulsion eller en opslæmning. Der kendes en række materialer, som forårsager eller fremmer i det mindste en vis gennemtrængning og/eller kvældning og/eller løsning og/elfer opløsning af smuds. Et basisk opvaskepræparat vil typisk indeholde en kilde til alkalinitet og en kilde til complexdan- 20 nelsesaktivitet. Sådanne præparater kan tilpasses til bekæmpelse af bestemte problemer, Fx kan det tænkes, at fjernelse af tepletter vil kræve inkorporering af blegemidler, mens produkter baseret på amylase kan være nyttige til fjernelse af stivelse uden alkalinitet.The sprayed aqueous dishwashing composition must be capable of flowing, but may for example be in the form of a solution, an emulsion or a slurry. A number of materials are known which cause or promote at least some penetration and / or swelling and / or solution and / or dissolution of dirt. A basic dishwashing preparation will typically contain a source of alkalinity and a source of complex formation activity. Such preparations can be adapted to combat certain problems, for example, it is conceivable that tea stains removal will require the incorporation of bleaches, while products based on amylase may be useful for removing starch without alkalinity.
25 Til illustrative formål kan en maskine til udøvelse af den foreliggende fremgangsmåde være en maskine med transportbånd og kan omfatte et forvaskeområde, et vaskeområde, et skylleområde, et område til endelig afskylning og et tørreområde. Rent vand tilføres kun til det område, hvor afsluttende afskylning Finder sted, og løber videre derefter på kaskade-maner mod forvaskeområdet i mod- 30 strøm i forhold til servicets transportretning.For illustrative purposes, a machine for carrying out the present method may be a conveyor belt machine and may comprise a pre-wash area, a wash area, a rinse area, a final rinse area, and a drying area. Pure water is supplied only to the area where the final rinse takes place, and then runs on cascading maneuvers towards the pre-wash area in counter current with respect to the service's transport direction.
Et simpelt produkt, der er rimelig effektivt til fjernelse af ophobede stivelsesrester og pletter kan sammensættes af følgende komponenter: DK 171583 B2 5A simple product that is reasonably effective at removing accumulated starch residues and stains can be composed of the following components: DK 171583 B2 5
Kaliumhydroxid 20-30 vægtprocent kelatdannende middel/midier 15-25 vægtprocent kalkudfældningshæmmende middel/midier ("threshold agent(s)") 2-4 vægtprocent 5 dispergerende polymer(er) 2-4 vægtprocent befugtningsmiddel/midler 1-2 vægtprocent resten vandPotassium hydroxide 20-30% by weight of chelating agent / medium 15-25% by weight of lime precipitant / medium ("threshold agent (s)") 2-4% by weight 5 dispersing polymer (s) 2-4% by weight wetting agent / agents 1-2% by weight of residual water
Optimering af et sådant produkt er både mulig og ønskelig. Et sådant produkt kan 10 blandes løbende med vand inden påsprøjtning ved en fortynding på ca. 2,5% igennem egnede sprøjtedyser placeret inden for vaskeområdet umiddelbart før eller efter området til konventionel vask. Sprøjtet service kan derefter passere gennem en del af vaskeområdet med pumperne slukket (medmindre der allerede er tilstrækkelig afstand mellem områderne), så at der opnås en kontaktperiode på 15 ca. 15 sekunder, inden det når til et yderligere vaskeområde eller skylleområde. Yderligere detergent kan tilsættes på konventionel måde på andre trin for at tilvejebringe yderligere pletfjemelse og for at forhindre belægningsdannelse på ma-skindele. Derefter fortsætter servicet til et endeligt skylletrin, hvor skyllemiddel kan tilføres.Optimization of such a product is both possible and desirable. Such a product can be mixed continuously with water before spraying at a dilution of approx. 2.5% through suitable spray nozzles located within the wash area immediately before or after the conventional wash area. Sprayed service can then pass through a portion of the wash area with the pumps off (unless there is already sufficient distance between the areas) so that a contact period of 15 approx. 15 seconds before reaching a further wash or rinse area. Additional detergents can be added in a conventional manner in other steps to provide additional stain removal and to prevent coating formation on machine parts. Thereafter, the service proceeds to a final rinse step where rinse aid can be added.

Efter læsning af tilsmudset service på transportbåndet bliver det i forvaskeområdet overhældt med overløbsvand fra vaskeområdet, hvilket vand har en temperatur på ca. 40°C. Alle grove rester eller relativt store mængder madrester bliver derved fjernet fra servicet. Dernæst passerer servicet ind i selve vaskeområdet. I 25 vaskeområdet oversprøjtes servicet med den højkoncentrerede detergentopløsning; hver dyse kan levere så lidt som 6 l/time, og typisk vil der være fra 3 til 10 dyser. Systemet er indrettet eller tilpasset således, at der ikke er noget, der forstyrrer den ønskede, forlængede, intime kontakt.After reading soiled service on the conveyor belt, it is poured in the pre-wash area with overflow water from the wash area, which water has a temperature of approx. 40 ° C. All coarse or relatively large quantities of food debris are thereby removed from the service. Next, the service passes into the wash area itself. In the wash area, the service is sprayed with the highly concentrated detergent solution; each nozzle can deliver as little as 6 l / h, and typically there will be from 3 to 10 nozzles. The system is arranged or adapted so that nothing disturbs the desired, extended, intimate contact.
30 Transportbåndets fremføringshastighed er fordelagtigt valgt således, at detergentopløsningens kontaktperiode er fra 5 til 100 sekunder, som regel ca. 10 sekunder, afhængig af opløsningens koncentration. En sådan kontaktperiode samt den høje koncentration af detergentopløsningen sikrer, at alle madrester på servicet, især fedt, stivelse, pletter og protein, bliver fjernet fuldstændigt, og at bakte-35 rier bliver destrueret.Advantageously, the conveying speed of the conveyor belt is chosen such that the contact period of the detergent solution is from 5 to 100 seconds, usually approx. 10 seconds, depending on the concentration of the solution. Such a contact period, as well as the high concentration of the detergent solution, ensures that all food residues on the service, especially fat, starch, stains and protein, are completely removed and bacteria are destroyed.

Efter denne kontaktperiode bliver de løsnede madrester sammen med den på-sprøjtede detergentopløsning afvasket i de efterfølgende trin ved anvendelse af konventionelle sprøjtedyser; vaskevæsken består dels af overløbsvand fra skyl-5 leområdet, dels af afskyllet koncentreret detergentopløsning samt eventuel yderligere tilført, doseret, komplementært opvaskepræparat. Ved anvendelse af fremgangsmåden ifølge den foreliggende opfindelse er der ikke længere behov for den periodiske kraftige rengøring eller den manuelle iblødlægning, som hidtil har været nødvendig.After this contact period, the detached food residues, together with the sprayed detergent solution, are washed off in the subsequent steps using conventional spray nozzles; the wash liquid consists partly of overflow water from the rinsing area and partly of rinsed concentrated detergent solution as well as any additional, dosed, complementary dishwashing liquid. Using the method of the present invention, there is no longer a need for the periodic vigorous cleaning or the manual soaking that has been hitherto necessary.
10 I det efterfølgende skylleområde bliver eventuelle løsnede mad- og smudsrester på servicet samt rester af vaskevæske afskyllet med rent vand med en temperatur på ca. 70°C. I området, hvor den afsluttende afskylning finder sted, sikrer tilførsel af rent vand, som har en temperatur på ca. 85°C, og som er tilsat skyllets middel, at der kun resterer en tynd vandhinde på servicet, hvilken hinde tørrer hurtigt i det efterfølgende tørreområde, enten ved hjælp af servicets varme eller ved tilførsel af varm luft.10 In the subsequent rinsing area, any loosened food and dirt residues on the service as well as remnants of washing liquid are rinsed with clean water at a temperature of approx. 70 ° C. In the area where the final rinse takes place, supply of clean water, which has a temperature of approx. 85 ° C, and added to the rinse means that only a thin water membrane remains on the service, which membrane dries quickly in the subsequent drying area, either by means of the service heat or by supply of hot air.
Ved anvendelse af den foreliggende fremgangsmåde opretholdes en pålidelig høj 20 standard af renhed for servicet.Using the present method, a reliable high standard of service purity is maintained.
