  10. 10. Food Processing Plant Layout. - air monitoring is required - internal air must travel from clean to dirty areas - high pressure zone : packaging areas - low pre UV-C ssure zone : shipping and receiving areas - Add UVC technology !
  11. 11. • Keeping coliform bacteria counts below required thresholds is a challenge for food processors. Time and costs required to achieve control are excessive. Coliform bacteria are a commonly used bacterial indicator of sanitary quality of foods and water. • Airborne micro-organisms such as germs, bacteria, fungi and viruses trigger health problems in humans and contaminate raw materials and fresh food in food production, leading to premature spoilage. • Air Quality is covered in UK legislation under COSHH regulations and the Health and Safety at Work Act 1974 which specify that employers owe "common duty of care" to employees and others who use or visit the premises. Furthermore the European standard VDI 6022 states that air conditioning plants should provide flawless air quality. • In accordance with VDI 6022, air conditioning plants should provide physiologically beneficial indoor climate conditions and ensure that the indoor air is of flawless quality. The VDI standard stipulates that health risks and a decreased sense of well-being caused by air contaminated by micro- organisms must be avoided. Contamination Issue. Why is clean air important?
  12. 12. • Air contaminated by bacteria, molds, yeasts and viruses causes microbial build-up on the heat exchange plates, primary and intermediate condensate drain pans of the cooling coils and eliminator sections in air handling units. This affects the system ducting, causing increased resistance to air flow and a loss in thermal efficiency. • UV-C based solutions from Soma Medical reduce continually the microbial contamination more than 90%. • We eliminate/reduce the need for manual cleaning of the coil. • The use of disinfectants / sanitizers in HVAC systems may be dangerous for workers and the produce it’s quality. ( • Our disinfection and sterilization systems are extremely low maintenance. How can UV-C Technology improve the HVAC efficiency?
  13. 13. Other benefits are : • Increased product yield and safety • Ability to reduce / eliminate the use of chemicals and/or preservatives • Longer product shelf life • Reduce customer complaints • Reduce product returns • Improve freshness of the products • Improves the hygiene standards • Stricter quality assurance • Fewer product losses results in higher profit Advantages of UV-C technology when used in food processing: UV-C decontamination systems can be used on a wide range of raw, cooked, or frozen food products (meats, poultry, seafood, vegetables, fruits, dairy products, nuts) prior to incoming storage, processing, or packaging, treatment of food contact surfaces.
  14. 14. • 40% fewer respiratory problems • 30% fewer mucous membrane problems • 50% fewer complaints about muscle pains • Fewer absences due to illness • Healthier and happier staff Source : ** Dick Menzies, Julia Popa, James A Hanley, Thomas Rand, Donald K Milton. Effect of ultraviolet germicidal lights installed in office ventilation systems on workers’ health and wellbeing: double-blind multiple crossover trial. The Lancet – Vol 362 – pp. 1785 - 1791, November 29 2003 – Advantages of UV-C Technology to Improve Health of Staff.
  15. 15. • Micro-organisms are everywhere and have an extremely high metabolism. In a hot and humid weather the number of molds per cubic meter of air increases exponentially. • Micro-organisms deposit mucus substances on surfaces which contaminates the food and causes microbial decay of the products. Usage of UV-C technology to destroy micro organisms. The cell nucleus of micro-organisms contains thymine (chemical element of the DNA). This element absorbs the UV-C radiation at a specific wavelength of 253.7 nm particularly well and changes to such an extent (formation of thymine dimers) that the cell is no longer capable of multiplying and surviving. Less micro-organisms means less contamination of food.
  16. 16. • UV-C radiation is light at a wavelength of between 280 and 100nm. The wavelength that is primarily responsible for destroying micro- organisms is 253.7nm. This has the greatest effect on the genetic make- up of the micro-organism's nucleus. Our UV-C lights are emit light on a spectral line of exactly 253.7 nm. • Special glass is used Soma Medical prevents the emission of wavelengths below 200nm that are responsible for the formation of ozone gas. Radiation traps in the system casings ensure that no radiation can escape outside. This means that UV-C radiation can be used without any health risk to people or impairment of food products. • UV-C disrupts the DNA or RNA structure of bacteria, viruses, molds and fungi, and yeast (including Listeria, Escherichia coli, Salmonella, Staphylococcus, and other microorganisms). • UVC is safe to use, leaves no surface residue, and will not chemically alter food products. Use UV-C radiation to destroy mold & viruses.
  17. 17. • The food trade & food industry require solutions that are simple to implement without interrupting production processes. • We provide standard solutions which can be quickly installed as wall or ceiling units. • We can also develop customized solutions for specific requirements tailored to the customer's needs. (UVC lights need to deliver high-output germicidal energy at low temperatures without loss of efficacy) • The United States Department of Agriculture and the Food and Drug Administration have approved UVC for surface decontamination, with no labeling required. • In 2000, the FDA approved UV-light as alternative treatment to thermal pasteurization of fresh juice products (US FDA 2000) Solutions for the food trade & food industry.
  18. 18. • Installation can be done in any type of air handling system, including those with limited space and/or access. • No costly modifications to the air handling system itself. Is necessary. • Germicidal effect is virtually immediate and continuous, as long as the lights are kept on and combined with Ozone in specific areas. • UVC lights keep coils , drain pans and other components clean and free of organic buildup, eliminating the time, cost, and potential hazards associated with chemical cleaning programs. • UVC lights also increase system efficiency, reducing energy and operating costs. HVAC energy savings of 15-20 percent or more are not uncommon. Efficiency of UVC systems? - Lower maintenance cost - More Healthy processing - Increased productivity - Higher ROI and earnings
  19. 19. • UVC is an alternative to traditional thermal processing. Applications include pasteurization of juices, post lethality treatment for meats, treatment of food contact surfaces and to extend the shelf-life of fresh produce. • In the food irradiation process, germicidal UV-C lamps are used in the food industry to prolong shelf life, preserve nutritional value, and reduce health hazards by sterilizing pathogens. • Germicidal UVC technology is a safe and cost-effective method that allows for compliance with strict local codes and FDA safety regulations. • UVC light destroys germs on packaging materials, working surfaces and some foods. • Germicidal UV-C technology destroys pathogenic micro-organisms in water used in the production of drinks without altering the taste, smell or pH. In general: application of UV-C in Food processing and Food storage.
  20. 20. • UV-C technology has a value for the bottled water market. This market continues to expand as bottled water consumption increases. Growing concerns with chemical and pharmaceutical waste entering our waste water treatment facilities make UV-C bottled water an attractive alternative. • applications include pasteurization of juices • Germicidal UVC lamps are used to disinfect packaging, filling equipment, conveyor belts, transport containers and working surfaces. Packaging consists of lids, cups, sealing and packaging foils for drinks and cool-chain foodstuffs. • Application areas : processing, warehousing, handling, produce department, salad bars, buffets, bakeries, restaurants, meat cases. UV-C technology can be applied in a wide spectrum. Many applications are possible.
  23. 23. Effect of Humidity levels on micro organisms.
  24. 24. Humidity meter.
  25. 25. Low Indoor Humidity Increases Droplet Nuclei Levels. ●Viruses Evaporate faster in Low Humidity levels thus creating More Droplet Nuclei. ●Low humidity allows droplet nuclei to stay airborne longer as the droplets do not absorb water weight which would cause them to fall to the ground. ●Indoor Air currents both created by HVAC systems and people movement assure that droplet nuclei will remain airborne Indefinitely. ●This allows HVAC systems to remove and redistribute droplet nuclei throughout the building to infect more occupants.
  27. 27. What is Ultraviolet Light and How does it work? Ultraviolet Germicidal (germ-killing) light is UV light in the “C” band (254 nanometres). It is invisible and is mostly filtered out our of sunlight before it reaches earth’s surface. UV- C light Sterilizes germs by destroying the A to T bond in their DNA. This prevents them from reproducing and they soon die. It was artificially created in the 1880’s and later commercially used to kill waterborne viruses & bacteria in France in 1909. By the 1930’s Duke University surgeons were using in in operating rooms to reduce airborne bacterial and viral infections. In the 1930’s and 1940’s UV light was used in schools to successfully prevent airborne measles epidemics.
  29. 29. HOW DOES UV-C WORK? Ultraviolet photons harm the DNA molecules of living organisms in different ways. In one common damage event, adjacent thymine bases bond with each other, instead of across the "ladder". This makes a bulge, and the distorted DNA molecule does not function properly.
  30. 30. WHY ARE MICROWATTS IMPORTANT IN UV-C? Microwatts are actually the main dosage unit of measurement for the calculation that determines the kill rate for every type of disease-causing agent (pathogen). The microwatt is equal to one millionth (10−6) of a watt. 10 −6 W µW microwatt

  41. 41. Example of UVC array of T-8 UVC lights on a conveyor belt.
  42. 42. Custom Made Solution. Ventilation for conveyor belts in the baking industry In the production of bakery products, contamination with micro-organisms that accelerate spoilage (mainly moulds) primarily occurs after the baking process. To a great extent these come directly from the ambient air whilst the bakery products are cooling down and during packaging. The products often cool down on conveyor belts where they are exposed to the ambient air without protection. If the conveyor belt is enclosed and at the same time supplied with disinfected air, air contamination is practically ruled out. The air is supplied via an air channel system - a protective fabric casing over the conveyor belt. The textile channel system is made of AIRTEX Bioactive fabric and has an anti- microbial effect thanks to nano-silver that is firmly integrated in the fibre matrix. The room air containing airborne germs no longer has any contact with the product. A further advantage is that the heat dissipates directly downwards which prevents condensation from forming.
  43. 43. Outbreak control measures might include: Requiring specific measures to clean and disinfect food facilities. Temporarily closing a restaurant or processing plant when an outbreak is suspected. Telling the public how to keep the food free of contamination . Recalling food items. Telling consumers to throw away contaminated food from their pantry or refrigerator. The use of UVGI through out the critical areas of your processing and incubation areas is paramount. Controlling an Outbreak NOT FOLLOWING THESE SOLUTION I.A.Q PROTOCOLS MIGHT AFFECT THE STATUS OF YOUR ESTABLISHMENT
  44. 44. Why are factories and food processing plants such havens for Flu and Viral Transmission? Air-conditioned environments! Many factories and food processing plants have air-conditioning which dry the air and producing low relative humidity levels indoors! This is the PERFECT environment for airborne Viral transmission and contagion. Low MERV Filter Ratings! Many air conditioning systems have low MERV rated filters like MERV 4-6. You need a MERV 13 or higher to have any real effect on airborne viral capture. No Ultraviolet Lights or TiO2 Photocatalyst Coating! Relatively few factories and food processing plants use ultraviolet lights or TiO2 Photocatalyst Coating . Factories and food processing plants with UV lights combined with TiO2 Photocatalyst Coating have enjoyed lower airborne viral transmission rates and higher indoor air quality. Bathrooms with ceiling exhaust fans! I know of no public bathroom design which incorporates floor level exhaust vents. Wang Kai xi demonstrated the efficiency of toilet aerosolization and dissemination.
  45. 45. Summary of EPA Recommendations…. 1. Seal your filter rack & HVAC system 2. Get the highest MERV rated filter that your filter rack and air handling fan can tolerate. 3. Put as UVGI lights systems in all critical areas. 4. Consider Bi-Polar Ionization, Photocatalytic Oxidation and 5. Magnetized Filtration Media Technologies for additional viral sterilization. 6. Install bathroom exhausts 1-12”above the floor. 7. Coughing/sneezing occupants stay at home or wear a mask.
  46. 46. IN CONCLUSION IF WE ENCOMPASS THE USE OF ALL THE 5 TECHNOLOGIES RECOMMENDED BY EPA THEN WE EFFECTIVELY HAVE A 24/7 IAQ SOLUTION PROTOCOL. MERV Rated Filters, H.E.P.A. Germicidal UV Lights Magnetized Air Media Filtration Bi-Polar Ionization Photo- Catalytic Oxidation (PCO) Comprehensive 24/7 Sterilization Protocol
