Description
- This application is a continuation of Application Ser. No. 10/316,513 filed Dec. 10, 2002 entitled “DEODORIZING AND SANITIZING EMPLOYING A WICKING DEVICE”.
- The present invention relates to a method and device employing a wicking system which allows continuous and controlled sanitation and deordorization.
- Chlorine dioxide has been found to be an especially effective disinfectant. As used herein, the term “disinfecting” shall be used to include sanitizing, deodorizing, sterilizing, or otherwise destroying or reducing germ populations. The term “germs” as used herein shall include bacteria, yeasts, molds, viruses or any micro-organism whose presence, and numbers, are deemed inimical to human or animal welfare. Its use has been found to be particularly advantageous where microbes and/or organic odorants are sought to be controlled on and around foodstuffs, as chlorine dioxide functions without the formation of undesirable side products such as chloramines or chlorinated organic compounds that can be produced when elemental chlorine is utilized for the same or similar purposes.
- Additionally, at concentrations which have been found to be effective for deodorization and for most antimicrobial applications, chlorine dioxide gas is also generally considered as safe for human contact because the concentrations required are so low.
- Certain difficulties are encountered with the use of chlorine dioxide in practice, however. Chlorine dioxide gas can be toxic to humans at concentrations greater than 1,000 ppm and it can be explosive at concentrations above about 0.1 atmosphere. Therefore, chlorine dioxide gas is not manufactured and shipped under pressure like other industrial gases, and conventional methods of on-site manufacture require not only expensive generation equipment but also high levels of operator skill to avoid generating dangerously high concentrations. These problems have substantially limited the use of chlorine dioxide to large commercial applications, such as water treatment and poultry processing, where the consumption of chlorine dioxide is sufficiently large that it can justify the capital and operating costs of expensive equipment and skilled operators for on-site manufacture. However, it is not practical to ship chlorine dioxide as a concentrated gas to the medium or small users.
- It has thus become common practice to employ a chlorine dioxide-liberating compound such as sodium chlorite powder which is much safer from the standpoints of storage, shipping and handling. Generation of the chlorine dioxide from sodium chlorite or other chlorine dioxide liberating compound is usually effected by addition of acid, bleach (hypochlorite), or chlorine to the chlorine dioxide liberating compound.
- However, the composition obtained from the interaction of the relatively high concentrations of sodium chlorite and acid materials used can be injurious to health. Significantly, the toxicity problem imposes severe limitations on the general utility of the disinfectant composition, particularly with respect to the treatment of human beings.
- Methods have been developed in an attempt to overcome the aforementioned problems, but improved methods of generating chlorine dioxide on a small scale are still desired.
- The present invention relates to methods and devices for providing a sanitizing gas, a sanitizing liquid, or both, to locations which are difficult to reach, in particular drains for water flow systems which can plug with mildew and mold, and head spaces for beverage machines and automatic ice making units, for example, which have areas which are difficult to clean and sanitize using standard methods. The methods and devices of the present invention find utility for providing a continuous and controlled treatment of such locations.
- In one aspect, the present invention relates to devices and methods for providing a sanitizing gas, a sanitizing liquid, or both, by reacting a first liquid chemical component and a second liquid chemical component in a reservoir to produce a gaseous sanitizing/deodorizing composition, a liquid sanitizing/deodorizing composition, or both. The device includes at least a first container for the first liquid chemical component and at least one reservoir wherein the liquid components are brought into contact. The first liquid chemical component is provided to the reservoir through the use of a wick or other capillary means. The second liquid chemical component may be provided in the reservoir, or may also be provided to the reservoir from a second container through the use of a wick or other capillary means.
- This device is particularly suitable for the production of chlorine dioxide wherein the acidic component is provided in excess either in the reservoir, or by wicking through the use of a wick which is larger than that employed for wicking of a metal chlorite composition.
- In another aspect, the present invention relates to methods and devices for the production of controlled quantities of chlorine dioxide at concentrations which are effective to function as a deodorant or a germicide. Aqueous chlorite compositions such as aqueous sodium chlorite are brought into contact at a controlled rate through capillary means, e.g. a wick or a capillary tube, with an acidic liquid composition which will react with the chlorite and form chlorine dioxide.
- The acidic liquid composition may either be kept stationary in a reservoir wherein the aqueous chlorite composition is “dripped” into the acidic liquid composition through the use of a wick or capillary tube, for example, or the acidic liquid composition may also be transported by capillary action to the common reservoir wherein the acidic liquid composition and the metal chlorite composition can start reacting.
- The reacting mixture may produce a gas which may be released into an enclosure such as an ice machine head space for deodorizing and sanitizing, and may also produce a liquid sanitizing and deodorizing composition which may be released into the drain of a water flow system such as an ice bin drain and/or a floor drain for the automatic ice making unit.
- Other systems which employ the use of a drain include wet bars, beverage machines, and so forth.
- The reacting mixture may be brought into contact with a drain through the use of gravitational forces through an overflow outlet, by siphoning, by dripping through a small outlet port or tube, and so forth.
- In another aspect, the present invention relates to a sanitizing and/or deodorizing system including a first container for holding a first liquid composition including at least one acidic compound, a second container for holding a second liquid composition including at least one compound capable of reacting with the acidic compound to form a sanitizing compound, and a reservoir equipped with an outlet port and/or vent. The first container further has a first conduit extending from the first container to the reservoir with a wick disposed in the conduit for transporting the first liquid to the reservoir. The second container further has a second conduit extending from the second container to the reservoir with a second wick disposed in the second conduit for transporting the second liquid to the reservoir.
- Alternatively, the second liquid may be provided in the reservoir in molar excess to the first liquid and the first liquid provided to the reservoir from the first container to the reservoir by the capillary action of a wick.
- From the reservoir, the liquid sanitizing mixture may be allowed to exit via an overflow outlet in the reservoir by gravitational forces through a conduit and to the location which is selected for treatment.
- The reservoir may also be vented or otherwise open to the atmosphere above it where it may be used to deodorize/sanitize enclosed spaces.
- In one embodiment of this invention, the device is employed to continuously treat a drain with a sanitizing composition to prevent a build-up of mold or mildew which may result in a clogged drain.
- In one embodiment, the device is employed to continuously provide controlled amounts of gas to the head space of an automatic ice making unit.
- The present invention finds particular utility for treating areas which are otherwise difficult to access. The present invention finds particular utility for the treatment of drains for water flow systems wherein mold and mildew may build up causing clogging of the drains.
- Furthermore, the present invention is particularly advantageous for treating smaller, enclosed spaces because a gaseous deodorizing/sanitizing composition may be produced in some embodiments. For example, small amounts of chlorine dioxide gas may be generated over a sustained period of time in amounts as low as about 0.5 to about 1.5 ppm. For some applications it is desirable to generate amounts as low as about 0.1 to about 0.5 ppm and more suitably about 0.1 to about 0.3 ppm. The latter range is particularly advantageous for treating the head space above the sump in an automatic ice making machine.
- Other sanitizing compositions include quaternary ammonium compounds and peracetic acid, for example.
- In another aspect, the present invention relates to a method of treating a drain for a device having a water flow system including the step of selectively transporting a liquid deliming and sanitizing composition from a reservoir to the drain by the capillary action of a wick, by dripping, or by siphoning of the liquid composition.
- The liquid deliming and/or sanitizing composition may be provided to the reservoir by the capillary action of a wick from a first container and/or second container. The deliming composition may be acidic and the sanitizing composition may include a metal chlorite.
- In another aspect, the present invention relates to a method of treating the head space in equipment having an automatic water circulation system including the steps of providing an acidic aqueous composition in a reservoir and selectively transporting an aqueous metal chlorite composition to the acidic aqueous composition by capillary action of a wick or other capillary means. Chlorine dioxide gas is emitted to the head space.
- The device and method of the present invention may be employed in combination with the device and method as described in commonly assigned copending US patent application attorney docket no. E14.2-9863/DUAL CLEANING AND SANITIZING SYSTEM incorporated by reference herein in its entirety.

In this particular embodiment, the quantity of product delivered is such that the reactants will have a 30 day life expectancy until replenishment is required. - The type of wick employed may be any standard cotton string or candle wick, for example. The candle wicks suitable may range in wick size from about 0.1 g/foot to about 0.5 g/foot including sizes of about 0.3 g/foot and about 0.4 g/foot.
- A device similar to the one described above is found in U.S. Pat. No. 3,334,789 the entire content of which is incorporated by reference herein.
-
FIG. 2 illustrates generally at 10 a two-wick embodiment of the device according to the present invention.Device 10 has afirst chamber 15 for containing an acid source in liquid form and asecond chamber 17 for containing a chlorite source in liquid form. Eachchamber conduit wick wick reservoir 23 where the acid and chlorite are mixed forming chlorine dioxide.Reservoir 23 is equipped with anoutlet 26 and anoverflow tube 27. Once the level of the sanitizing mixture is at or above the level ofoutlet 26 then the sanitizing liquid will drain fromreservoir 23 throughoverflow tube 27 to the desired location such as a drain for a water flow system. This device may be employed for treating any type of area which is capable of draining, and which is conducive for antimicrobial growth such as mold and fungus. - In the embodiment described above,
first chamber 15 may contain an acidic deliming composition such as LIME-A-WAY® available from Ecolab, Inc. in St. Paul, Minn., andsecond chamber 17 may contain an aqueous sodium chlorite sanitizing composition. LIME-A-WAY® is a phosphoric acid based delimer available from Ecolab, Inc. in St. Paul, Minn. Phosphoric acid is suitable for use because it not hazardous for contact with food. Other examples of useful delimers include, but are not limited to: sulfuric acid, hydrochloric acid, citric acid, and so forth. - An excess amount of acid may be transported from
first chamber 15 toreservoir 23 by the capillary action of awick 19 along with the sodium chlorite from thesecond chamber 17 toreservoir 23 by the capillary action of awick 21.Wick 19 is desirably larger thanwick 21 in order to provide an excess amount of acid over sodium chlorite. A reaction begins inreservoir 23 between the sodium chlorite and the acid wherein chlorine dioxide in both a gaseous and a liquid state, is produced. This reaction may be represented by the following general formula:
5 NaClO2+(4/n)HnX=4ClO2+NaCl+(4/n)NanX+2H2O - Once the level of the acid/sodium chlorite mixture has reached an overflow level above
outlet 26, the aqueous chlorine dioxide containing composition may then exit throughoutlet 26 and proceed by gravitational forces throughoverflow tube 27 to drain 31 shown below inFIG. 3 . Alternatively, the aqueous composition may be siphoned, may be dripped through a small outlet in the bottom of the reservoir, or may also be transported by the capillary action of a wick fromreservoir 23 to a drain (shown inFIG. 3 , below), for example. - Chlorine dioxide gas may also escape through
top 41 ofreservoir 23. Alternatively, a vent (not shown) may be provided intop 41 of thereservoir 23. In this fashion, chlorine dioxide gas may be used as an antimicrobial agent to treat the head space of an enclosed area such as in a beverage machine, ice machine, or the like. This is particularly advantageous for treating areas, such as corners, or behind equipment parts, which are otherwise difficult to access for cleaning. - Chlorine dioxide is particularly suitable for use herein because it partitions itself in both the gas phase and the liquid phase. Chlorine dioxide partitions at a ratio of about 5 ppmv (partial volume) in air and about 1 mg/liter in water under cold water conditions. This partitioning effect allows for sanitization of areas that are difficult to reach with a liquid, i.e. the non-wetted areas. For example, in high humidity and temperature, mold, yeast, fungi, and other microbes may build in head space areas of equipment, such as ice machines, where it is difficult to access for cleaning purposes. Such partitioning makes chlorine dioxide particularly suitable to sanitize the head space of an ice machine, for instance.
- However, this is not to say that other sanitizers may not be employed in a liquid state for treatment of drains, for example. Such other useful sanitizers include, but are not limited to: a quaternary ammonium composition, a peracetic acid composition, and so forth.
- The
entire device 10 may be manufactured such that it is disposable when the reactants have been depleted. Alternatively,chambers larger chamber 15. - The above device may be optionally equipped with a battery operated alarm, or LED, which is capable of indicating when one and/or both reactants have been depleted.
- In another embodiment as shown in
FIG. 3 , a two-wick embodiment of thedevice 10 as shown in an enlarged form inFIG. 2 , is shown in combination with anice machine 50 whereindevice 10 is employed to treat bothice bin drain 31 andfloor drain 33.Device 10 is shown withdual chambers chamber 15 may contain an acid source in the form of a liquid, for example, andchamber 17 may contain a chlorite source in the form of a liquid. Awick 19 inside aconduit 18 is in contact with the acid source inchamber 15 and awick 21 inside aconduit 22 is in contact with the chlorite source inchamber 17.Conduits wicks reservoir 23 which is equipped with anoutlet 26 andoverflow tube 27 which continues throughice machine 50 and down to the ice bin drain 31 from which it drains intofloor drain 33 via aplumbing conduit 35. Alternatively,ice bin drain 31 may be arranged directly overfloor drain 33 such that little or no plumbing conduit is required. - Alternatively,
overflow tube 27 may be equipped with anadditional branch conduit 37 which drains directly intofloor drain 33, as shown.Overflow tube 27 may be used alone, or in combination withbranch conduit 37. - As an excess of acid is desirable,
wick 19 employed for transporting the acid toreservoir 23 is desirably of a larger grade thanwick 21 employed for transporting the chlorite source toreservoir 23. - Additionally,
reservoir 23 may be configured such that it is open to thehead space 40 ofice machine 50 as shown in this embodiment allowing chlorine dioxide gas to escape and treat areas inhead space 40, such as the corners, which are typically difficult to reach using standard cleaning methods.Head space 40 is also conducive for formation of microbial growth such as molds and fungus due to the presence of moisture, and it is also warmer than other parts ofice machine 50. - The
ice bin drain 31 could be arranged such that it is directly overfloor drain 33 or it may be connected tofloor drain 33 via aplumbing conduit 35 as shown in this embodiment. In this manner, bothice bin drain 31 andfloor drain 33 are treated with chlorine dioxide. This will help to prevent clogging ofdrains - While in this embodiment, the device is shown in combination with an ice machine, the invention certainly may find utility to treat drains for any water flow system.
-
FIG. 4 shows generally at 10, an alternative one-wick embodiment according to the present invention. In this embodiment,device 10 has only onechamber 17 for containing a chlorite source.Chamber 17 is equipped with aconduit 22 containing awick 21.Device 10 also has areservoir 23 but in thisinstance reservoir 23 contains the acid source.Wick 21 transports the liquid having chlorite ions fromchamber 17 toreservoir 23 wherein the acid and the chlorite ions react to form chlorine dioxide.Reservoir 23 is further equipped with anoverflow conduit 27.Overflow conduit 27 and thereservoir 23 are in fluid communication viaoutlet 26. When the level of liquid sanitizer inreservoir 23 reaches a level aboveoutlet 26, then the liquid drains throughoverflow conduit 27 to the desired location such as a drain for a water flow system. - The device of the present invention may be advantageously used in combination with other treatment systems for water flow systems such as those described in copending attorney docket number E14.2-9863, in U.S. Pat. No. 5,752,393, and in U.S. Pat. No. 5,289,691, for example, each of which is incorporated by reference herein in its entirety. The present invention is useful for treating areas where a build-up of mold and mildew may occur such as moist areas. Such build-up may be compounded if the area is also warm.
- The present invention is particularly advantageous for treating drains for water flow systems.
- The device of the present invention may also find utility for deodorizing in small areas such as athletic lockers, food storage containers, walk-in freezers, storage closets such as those for cleaning products, and so forth. In such applications where only deodorizing is required, no
outlet 26 oroverflow tube 27 are required. - The above disclosure is intended for illustrative purposes only and is not exhaustive. The embodiments described therein will suggest many variations and alternatives to one of ordinary skill in this art. All these alternatives and variations are intended to be included within the scope of the attached claims. Those, familiar with the art may recognize other equivalents to the specific embodiments described herein which equivalents are also intended to be encompassed by the claims attached hereto.
