Sonic Cleaning Beverage Dispensers and Bottling Equipment Valves

Sonic cleaning beverage dispenser nozzles and valves in restaurants and fast food chains is a fast and thorough method of removing sugary build up, cocoa, coffee stains and other residues that could lead to an unsatisfactory inspection rating.

The same holds true for cleaning bottling equipment filling valves used on commercial food and beverage processing lines.

That’s because the intense but safe scrubbing action produced by the implosion of billions of minute bubbles in a biodegradable ultrasonic cleaning solution reaches and removes contaminants from all dispenser and valve surfaces immersed in the solution.

The bubbles are produced by generator-powered transducers bonded to the bottom and/or the sides of the cleaning tank and vibrating at ultrasonic frequencies such as 25 or 45 kHz. No amount of time in a dishwasher or hand scrubbing can match sonic cleaning in terms of speed, thoroughness and efficiency. Moreover, cleaning solution formulas used in ultrasonic cleaners are not compatible with dishwashers.

Equipment Selection for Beverage Dispensers and Bottling Lines

iUltrasonic offers equipment in a variety of sizes and frequencies to meet the cleaning needs of any sized operation – ranging from the corner deli, coffee houses and cafeterias to commercial scale food and beverage packagers.

Note: When selecting equipment size keep in mind that filling and dispensing valves must be fully immersed in the cleaning solution. Basket dimensions, not interior tank dimensions, should guide your selection.

An example for small-scale operations is the 45 kHz, ½ gallon capacity Crest EH050CR with separately purchased stainless steel mesh basket dimensions 5.5 x 5 x 3.5 inches deep. This compact bench-top ultrasonic cleaner is equipped with a heater, timer and a sweep function, the latter to insure even distribution of sonic cleaning action throughout the solution.

At the other end of the scale contact us about roller-mounted industrial ultrasonic cleaners such as the X-tra Basic series in 6 solution capacities from 5.8 to 57 gallons that can be moved to locations throughout the facility, requiring only a power source. Ask us about the Flex series that provide a slight vertical oscillation of ±2 cm (Flex 1) that can be coupled with a spray rinsing station or an ultrasonic rinse tank (Flex 2) for cleaning and rinsing bottling equipment valves before they are reinstalled.

Selecting a Beverage Dispenser Cleaning Solution Chemistry

While there is a vast selection of ultrasonic cleaning solution chemistries available selecting the correct formulation requires understanding the nature of soils being removed. Rather than provide examples we suggest you contact the sonic cleaning professionals at iUltrsonic to discuss your particular challenges.

We’ll be glad to recommend the formulation best suited to your challenges and provide operating instructions on its use – including dilution suggestions and cleaning temperatures.

Establishing a Beverage Dispenser Cleaning Procedure

Here is a simplified cleaning procedure. With practice you will develop your own routine.

  1. Fill the ultrasonic cleaner tank half full of water and add the required amount of cleaning solution concentrate for a full tank. Continue adding water to the fill line.
  2. Activate the ultrasound to mix and degas the solution. Depending on tank volume this should take 10 to 20 minutes. Degassing drives off trapped air and contributes to cleaning efficiency. Some models of ultrasonic cleaners are equipped with a degas function to speed the operation.
  3. Set the thermostat to the recommended cleaning temperature. Place dispensers and valves in the basket taking care that they do not contact each other.
  4. When ready lower the basket into the cleaning solution, close the lid to reduce noise and slow evaporation, and set the timer for 5 minutes. Cleaning time varies depending on the number and condition of the parts.
  5. At the end of the cycle remove and inspect. If satisfied rinse off the cleaning solution and let the parts dry before reassembly.

Repeated use of the solution will eventually reduce its effectiveness. Drain the tank and dispose of the solution according to local regulations. Clean the tank according to the operating instructions. Then prepare and degas a fresh batch.
