1Garlic Processing - Bakersfield, CA Spray Bar Rinse SystemClearWater Tech, LLC.
2Garlic processing The Company - Located in Bakersfield, CA - In business over 20 years- Serves large companies as a foodingredient supplier- Also serves prisons, schools, restaurantchains, etc.
3Garlic processing The Company - products Whole peeled garlic Private-label garlic pureesJalapeno pepper products
4Sodium hypochlorite spray bar Previous system-Sodium hypochlorite spray barSpray bar rinse of whole peeled garlicGoals: 1. Reduction of aerobic plate counts (APCs) from in the 100,000s to the 10,000s Reduce lactic acid bacteria (spoilage) and mold.ppm solution of sodium hypochloriteStill in place as back-up for ozone system
6Challenges presented by Sodium hypo systemSodium hypo was pitting stainless steel rollers and other exposed stainless steelMaintenance costs - High TDS from sodium hypo was plugging spray bars, corroding the feed pump and plumbingSodium hypo was adding to issues in the wastewater pondPond is directly over source water aquifer
7Challenges presented Air scrubbing (carbon) required Odor from ppm sodium hypoSodium hypo reacting with organics,causing strong ammonia odorLong term cost - $3,000/year in sodium hypo. With maintenance, system was costing$500 - $600/monthPotential for sodium hypo residual on product
8The solution - ozoneOzone system installed in March of 2002 on garlic spray bar rinse systemInstalled in single pass 13 gpmMaintains a dissolved ozone level of 1.3 ppmCapable of up to 5.0 ppm dissolved ozone
9Hdo3-11 skid mount ozone delivery system The ozone systemHdo3-11 skid mount ozone delivery systemSkid-mounted, pre-plumbedand pre-wiredIncludes the following components:20 gram/hour, variable outputCD ozone generatorStainless steel contact vesselFully integrated dissolvedozone monitorFull instrumentation
10Hdo3 system - on the job - If placed outdoors - Requires protection from wind, rain, dust,moisture, and impacts.
11The Ozone SystemThe plant’s source water comes from a deep well on the propertySource water is fed directly to the HDO3 systemHDO3 puts 1.3 ppm dissolved ozone into water, which is fed directly to the spray barWater 20 psiSpray heads increased in size toaccommodate lower psi of ozone system
12the ozone system4-20 mA signal from integrated dissolved ozone monitor controls output of ozone generatorSystem also includes a 10 gpm wash down wandAmbient ozone monitor installed to insure safety of workers
14Ozone system results 20-30% reduction in APCs from chlorine system Check approx. twice/monthAnything below 10,000 is acceptable
15Ozone system results Reduced maintenance costs Pitting of stainless steel rollers eliminatedSpray bar plugging (from high TDS of sodium hypo) & corrosion eliminated. Saves $500-$600/month in materials & maintenance costsAir scrubbing system shut down completely, saving approx. $150/month in operating & maintenance costs
16Ozone system resultsWastewater from spray bar system now has <1 ppm sodium hypoNo potential for chemical residual on product
17- Easier to get product certified “organic” using ozone Other System BenefitsReliability - The company reports more consistent sanitation results with reduced system maintanence requirements.Marketing- Easier to get product certified “organic” using ozone- Food safety is an important issue and ozone helps - both in employee safety (chemical handling) and food quality (reduced spoilage)
18Other Plant Applications Plans to use the ozone system for equipment washdown & hard surface cleaning (10 gpm spray wand is in place)Considering ozone for spray bar rinse in jalapeno processing line and garlic puree processingDisinfection of process water
19Other systems available Mobile Wash downWall mounted low flow systems• Spray Bar• CIP System• Flume• Surface Sanitizer• Equipment Wash down
