Abstract

A system using electrochemically-activated water (ECAW) for manufacturing, processing, packaging, and dispensing beverages. The system uses ECAW solutions in the beverage facility clean-in-place system to achieve improved microbial control while greatly reducing water usage and reducing or eliminating the use of chemical detergents and disinfectants.

Claims

1. In a process for cleaning-in-place at least a portion of a beverage processing system wherein said process uses an overall total volume of water and said process comprises the steps of (a) delivering an amount of an aqueous rinse through said portion of said beverage processing system and then (b) delivering an amount of an aqueous disinfectant solution through said portion of said beverage processing system, said amount of said aqueous rinse and said amount of said aqueous disinfectant solution together being effective to obtain a level of microbial control therein, the improvement comprising

reducing said overall total volume of water used in said process and reducing said amount of said aqueous disinfectant solution used in step (b) without reducing said level of microbial control by using an electrochemically-activated water anolyte solution as said aqueous disinfectant solution in step (b) and

further reducing said overall total volume of water used in said process and reducing said amount of said aqueous rinse used in step (a) without reducing said level of microbial control by using an aqueous electrochemically-activated water anolyte dilution as said aqueous rinse in step (a).

2. The process of claim 1 wherein the improvement further comprises said electrochemically-activated water anolyte solution used in step (b) comprising an anolyte which, when in undiluted form, has a pH in a range of from about 4.5 to about 7.5 and an oxidation-reduction potential of at least ⁺650 mV.

3. The process of claim 2 wherein the improvement further comprises said electrochemically-activated water anolyte solution used in step (b) being said anolyte in undiluted form.

4. The process of claim 2 wherein the improvement further comprises said electrochemically-activated water anolyte solution used in step (b) being an aqueous dilution of said anolyte.

5. The process of claim 4 wherein the improvement further comprises said aqueous dilution of said anolyte comprising at least 50 parts by volume of non-electrochemically-activated water per 50 parts by volume of said anolyte.

6. The process of claim 1 wherein the improvement further comprises said aqueous electrochemically-activated water anolyte dilution used in step (a) comprising at least 60 parts by volume of non-electrochemically-activated water per 40 parts by volume of an anolyte which, when in undiluted form, has an oxidation-reduction potential in a range of from about ⁺300 mV to about ⁺1200 mV and a pH in a range of from about 2 to about 8.

7. The process of claim 6 wherein the improvement further comprises said anolyte, when in undiluted form, having a pH in a range of from about 4.5 to about 7.5 and an oxidation-reduction potential of at least ⁺650 mV.

8. The process of claim 6 wherein the improvement further comprises said aqueous electrochemically-activated water anolyte dilution used in step (a) comprising about 95 parts by volume of said non-electrochemically-activated water per 5 parts by volume of said anolyte.

9. The process of claim 1 wherein said portion of said beverage processing system comprises:

a beverage ingredient mixing line;

a filling line for filling bottles or filling other product packages;

or a combination thereof.

10. The process of claim 9 wherein said beverage processing system is a system for processing a carbonated soft drink, a brewed beverage, a fruit beverage, a fermented beverage, a vegetable beverage, a sports drink, a coffee drink, or a combination thereof.

11. In a process for cleaning-in-place at least a portion of a beverage processing system wherein said process uses an overall total volume of water and said process comprises the steps of (a) delivering an amount of an aqueous cleaning solution through said portion of said beverage processing system, then (b) delivering an amount of an intermediate aqueous rinse through said portion of said beverage processing system, and then (c) delivering an amount of an aqueous disinfecting solution through said portion of said beverage processing system, said amount of said aqueous cleaning solution, said amount of said intermediate aqueous rinse, and said amount of said aqueous disinfecting solution together being effective to obtain a level of microbial control in said portion of said beverage processing system, the improvement comprising reducing said overall total volume of water used in said process and reducing said amount of said aqueous cleaning solution used in step (a) and said amount of said aqueous disinfecting solution used in step (c) without reducing said level of microbial control by:
