"Misinformation about pasteurization remains widespread more than 80 years after demonstration of its effectiveness and more than 50 years after the publication of a comprehensive review concluding that pasteurization inactivates disease causing microbes without adverse effects on health or nutrition.

Those who criticize pasteurization can be persuasive to unsuspecting consumers, in particular when they invoke scientific studies. One can always find a study to defend a position, but responsible scientists and health professionals don't pick and choose studies for this purpose. Rather, they strive for objectivity, considering only quality evidence and only in its entirety."

EPA Mandates reduction of Bromates in drinking water.

"PurePass" meets and exceeds ALL the following EPA/FDA requirements and standards for bottled water without the creation of BROMATES and the total elimination of micro-organizms

The BROMATE problem solved with the "PurePass" System

The IDD in-line "PurePass" Oxine dosing units are fully automatic with sensors and alarm control for dosing spring water product with low levels of Oxine for "in-package" microbial stabilization and Bromate elimination.

These units are also adapted for dosing liquid concentrates into products such as minerals, fluoride, disinfectants, etc.

The IDD "PurePass" automatic Oxine activation and distribution system is used for container, cap and filling line sanitization during the filling process.

A typical skid mounted fully automated "PurePass" flash pasteurization system with CIP/SIP and sterile product tanks. These systems are used for carbonated and non-carbonated products and form a part of our sanitary filling systems for water, juice, beer, tea, etc. into cans, PET and glass bottles. Size and output is rated to suit the filling line in the range of 500 to 60,000 liters per hour.

"PurePass" savings for Juice process and packagers

COST ANALYSIS
"Hot Fill" vs. "PurePass"

IDD's "PurePass" technology offers a proven, economical method of sterile (aseptic) filling for juice and water based products that are carbonated or non-carbonated.

To demonstrate the most important and practical savings the following is an example of the savings that are recognized when using "PurePass" instead of "Hot Fill".

PACKAGE ASSUMPTIONS:

1. Bottling line, hot filling a single strength juice at 100 gallons per minute into 64 ounce (2 liter) "Heat Set" bottles.
2. A "Heat Set" 64 ounce PET bottle (PEN/PET mix), is 4cents per bottle more expensive than a PET bottle.

Assuming 100% efficiency the output would be 200 bottles per minute. Multiplied by the difference in cost between "Heat Set" and PET bottles of 4 cents per bottle.
equals: $998,400.00 per year savings.

"Hot Fill" ASSUMPTIONS:

1. "Hot fill" juice is heated from 60F to 190F at 80% efficiency.
2. "Hot fill" bottle cooling water is 50F and lowers the temperature of the bottle by 70F to 120F.
3. Tunnel cooling thermal efficiency 20:1 ratio (ref. P.Kidger, 1978 technical paper).
4. Natural Gas is a $1.00 per Therm - 100,000 BTU per Therm.
5. Water is 0.0013 cents per gallon.

Based upon 100% loss of energy and water the following would apply on the above assumptions:
Heat input to the juice of 7,956,000 BTU/Hr. equals: $165,485.00 per year.
Cooling water usage cost of 120,000 GPH. equals: $324,480.00 per year.

"PurePass" ASSUMPTIONS:

1. The "PurePass" plate heat exchanger operates at 92% regeneration efficiency.
2. The "PurePass" Oxine sanitizer is $12.50 per gallon.

Assuming all of the above, the heat input to the juice when the system is at operating temperature is 7,956,000 BTU/Hr. with 92% recovered by "PurePass". Therefore the operating heat input of 636,480 BTU/Hr. equals: $13,238.80 per year.

The cost of "PurePass" Oxine at 50ppm for continuous automated sanitizing and wash down sanitizing at 100ppm. equals 172.5 gallons "PurePass" Oxine per year, equals: $2,156.00 per year.

"PurePass" savings per year equal: $1,472,970.00

"PurePass" price (incl. installation) equals: $400,000.00

Return on Investment (ROI) equals: <3 months based upon 2001 costs.
