Chlorine Dioxide for Bewerages

Food & Beverage Processing – Chlorine Dioxide

Food & Beverage Processing – Chlorine dioxide (ClO2) provides excellent microbiological control for the food and beverage processing sectors in areas including brewing and bottling, fruit and vegetables (FDA approved application), poultry and other meats, fish; and dairy processes. Chlorine
dioxide also provides excellent microbiological control in flume waters, packaging operations and process disinfection.

  • Fruit and vegetable processing
  • Poultry processing
  • Food contact paper manufacture
  • Cleaning pasteurizers, warmers and coolers
  • Disinfection of packing operations
  • Flume water control
  • Water treatment
  • Equipment disinfection
  • Disinfection of tankers, vehicles and transportation vessels

Chlorine dioxide does not react with most “organics” in flume water; this makes it a very effective disinfectant. It is also an excellent odour neutralizer, helping to neutralize foul smelling odours including secondary and tertiary amines formed in the meat packing industry. Some specific applications for chlorine dioxide include:

Cleaning in place (CIP) and sanitizing operations

Chlorine dioxide can be very effective when used as the final sanitizing rinse in CIP systems,including filler rooms. Typically applied at between 2 and 5 ppm (where its kill-rate is in the order of 60 to 90 seconds) it leaves no toxic residues to interfere with other chemical/biochemical
processes. Chlorine dioxide works quickly and breaks down into inert compounds. Its unique chemistry produces no toxic organo-chlorine by-products (such as THM’s) and is therefore an environmentally friendly alternative to traditional sanitizers. Chlorine dioxide is also a very efficient, proven virucide and fungicide and is effective in destroying detrimental wild yeast strains.

Cleaning pasteurisers, bottle/can warmers and coolers

Chlorine dioxide effectively controls both free floating (planktonic) and attached (sessile) microorganisms. Sessile bacteria flourish in biofilms that build up due to ideal environmental conditions (temperature, nutrients, etc.). Biofilm build-up occurs on heat exchange surfaces, in pipes, lines, orifices and pumps. The resulting inefficiencies cost money on wasted energy, down time and repairs. Chlorine dioxide is the best available technology for controlling biofilms in these systems. Additionally, the longer these waters can be retained in a sanitary condition, the more money is saved in water costs, water discharge; and energy to heat replacement water. Chlorine dioxide can be periodically batch loaded into the water system or metered on a timed basis. This can extend pasteuriser waters 4 to 6 times their previous discharge cycle.

Chain and conveyor line lube injection

Chlorine dioxide can be injected into lubrication streams for effective slime control on conveyor lines.This allows for significantly longer run times between shut downs for cleaning, resulting in dramatic cost reductions. By attacking the biofilms attached to the conveyors and the underlying rails, various soils are loosened and the natural cleaning action of the lube is enhanced. Chains and conveyors run more smoothly, with less wear on chains and motors. Additionally, even small levels
of chlorine dioxide will help to effectively deodorize the line.

Filler head assemblies

Chlorine dioxide solutions can be sprayed on filler head assemblies in 10-second bursts during breaks and lunch. The spray coats all surfaces attacking biofilms, inhibiting bacterial growth and deodorizing the surrounding environment.

Water filtration and distribution system disinfection

Chlorine dioxide effectively controls both planktonic and sessile microorganisms. Because planktonic cells are much easier to destroy, a disinfection procedure often produces excellent results initially, but within 7 to 10 days the counts return. Chlorine dioxide is able to penetrate, disrupt and destroy the biofilm where chlorine is completely ineffective.

Mould and odour control

Misting of chlorine dioxide solutions into air streams prevents the spread of mould and wild yeast.This controls “off-tastes” in the product. Chlorine dioxide is also an excellent odour neutralizer,helping to control secondary and tertiary amines.

Sanitation of tanker trucks, wagons and transportation vessels

Chlorine dioxide solutions are effective for sanitizing and removing biofilms from the internal surfaces of tanker trucks, wagons and transportation vessels. A thorough sanitizing rinse of chlorine dioxide with close attention to overhead surfaces can improve the quality of product and significantly extend its shelf life.
