1 Spray Bar Rinse System ClearWater Tech, LLC. Garlic Processing - Bakersfield, CA

2 The Company - Located in Bakersfield, CA - In business over 20 years - Serves large companies as a food ingredient supplier - Also serves prisons, schools, restaurant chains, etc. Garlic processing

3 The Company - products –Whole peeled garlic –Private-label garlic purees –Jalapeno pepper products Garlic processing

4 Spray bar rinse of whole peeled garlic –Goals: 1. Reduction of aerobic plate counts (APCs) from in the 100,000s to the 10,000s. 2. Reduce lactic acid bacteria (spoilage) and mold. – ppm solution of sodium hypochlorite –Still in place as back-up for ozone system Previous system- Sodium hypochlorite spray bar

5 Spray bar rinse system

6 Sodium hypo was pitting stainless steel rollers and other exposed stainless steel Maintenance costs - High TDS from sodium hypo was plugging spray bars, corroding the feed pump and plumbing Sodium hypo was adding to issues in the wastewater pond –Pond is directly over source water aquifer Challenges presented by Sodium hypo system

7 Air scrubbing (carbon) required –Odor from ppm sodium hypo –Sodium hypo reacting with organics, causing strong ammonia odor Long term cost - $3,000/year in sodium hypo. With maintenance, system was costing $500 - $600/month Potential for sodium hypo residual on product Challenges presented

8 Ozone system installed in March of 2002 on garlic spray bar rinse system Installed in single pass 13 gpm –Maintains a dissolved ozone level of 1.3 ppm –Capable of up to 5.0 ppm dissolved ozone The solution - ozone

9 Skid-mounted, pre-plumbed and pre-wired Includes the following components: –20 gram/hour, variable output CD ozone generator –Stainless steel contact vessel –Fully integrated dissolved ozone monitor –Full instrumentation The ozone system Hdo skid mount ozone delivery system

10 - If placed outdoors - Requires protection from wind, rain, dust, moisture, and impacts. Hdo 3 system - on the job

11 The plant’s source water comes from a deep well on the property Source water is fed directly to the HDO 3 system HDO 3 puts 1.3 ppm dissolved ozone into water, which is fed directly to the spray bar –Water 20 psi –Spray heads increased in size to accommodate lower psi of ozone system The Ozone System

12 4-20 mA signal from integrated dissolved ozone monitor controls output of ozone generator System also includes a 10 gpm wash down wand Ambient ozone monitor installed to insure safety of workers the ozone system

13 Conveyor system and ambient ozone monitor

14 20-30% reduction in APCs from chlorine system Check approx. twice/month Anything below 10,000 is acceptable Ozone system results

15 Reduced maintenance costs –Pitting of stainless steel rollers eliminated –Spray bar plugging (from high TDS of sodium hypo) & corrosion eliminated. Saves $500- $600/month in materials & maintenance costs –Air scrubbing system shut down completely, saving approx. $150/month in operating & maintenance costs Ozone system results

16 Wastewater from spray bar system now has <1 ppm sodium hypo No potential for chemical residual on product Ozone system results

17 Click to edit Master text styles Second level Third level Fourth level Fifth level Other System Benefits Reliability - 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)

18 Click to edit Master text styles Second level Third level Fourth level Fifth level Other 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 processing Disinfection of process water

19 Mobile Wash down Wall mounted low flow systems Spray Bar CIP System Flume Surface Sanitizer Equipment Wash down Other systems available
