Assignee:

Ecolab Inc. - St. Paul MN

International Classification:

US Classification:

134 252, 134 3, 134 41, 134 26, 134 29, 134 36, 510514, 510521, 510522, 510524

Abstract:

Thus use of a post detergent step for removing aqueous residue from ware combined with a subsequent step using a potable rinse or a dilute solution of an aqueous food grade rinse aid to rinse alkaline washed ware provides significant advantages. The two step rinse method insures complete and sanitary cleaning of ware while permitting the use of different formulations in the post detergent step and the subsequent rinse step. Such process conditions permit the use of differing times and temperatures in the post detergent step and in the rinse step and permits the use of different formulations in the post detergent step and in the rinse step.

US Classification:

8158, 68 191, 68 20

Abstract:

A method and apparatus provide for an automated fragrance dispenser for the application of a fragrance to dry fabrics during an industrial laundering process. In one embodiment, the fragrance dispenser is positioned outside the dryer, and preferably on the exit side of the steam tunnel in the laundering process. The fragrance dispenser includes a sensor for determining whether the garment passing on the conveyor is the type of garment to which the fragrance is to be applied, for example, a uniform shirt versus pants. The fragrance dispenser also includes a delivery system for applying the fragrance to selected garments. The delivery system also includes a timing device for dispensing the fragrance onto the garment for a controlled amount of time. In an alternative embodiment of the present invention, automated application of the fragrance to fabrics is provided in the dryer within the laundering process. The fragrance dispenser according to this embodiment includes a product media located in the air intake environment of the dryer, and a delivery system for applying the fragrance to the product media.

Abstract:

A method and apparatus dispenses first and second fragrances by utilizing a fog nozzle in a ductwork of a facility. The first fragrance is dispensed, at intervals, through the fog nozzle into the ductwork and the second fragrance is dispensed after the first fragrance is dispensed, wherein fragrance desensitivity is reduced.

Abstract:

A method and apparatus provides for dispensing a liquid concentrate. The source pressure of a liquid diluent is changed by a boost pump () to bring the pressure of the diluent to an elevated pressure. The diluent then enters an aspirator assembly () wherein the concentrate and diluent are mixed to form a use solution. The dynamic pressure of the diluent entering the aspirator assembly () is sufficient so that the amount of concentrate delivered over time is more constant.

Abstract:

A concentration monitor for monitoring a concentration of a plurality of use solutions, each of the plurality of use solutions being, at least, a concentrate in a diluent, each of the plurality of use solutions having a resistivity which varies as a function of both temperature and an amount of the concentrate contained in a given amount of the diluent. A resistivity probe is adapted for use with at least one of the plurality of use solutions for taking a measurement related to the resistivity of the at least one of the plurality of use solutions. A temperature sensor is adapted for use with the at least one of the plurality of use solutions for taking a measurement related to the temperature of the at least one of the plurality of use solutions. A controller calculates the concentration of the at least one of the plurality of the use solutions based upon a predetermined algorithm using the resistivity and the temperature for the particular one of the at least one of the plurality of use solutions, the algorithm being based upon knowledge of the at least one of the plurality of use solutions being measured.
