20 Ton Industrial FRP Counter Flow Cooling Tower - Agriculture Food Processing
High-Temperature Short-Time (HTST) pasteurization at 72 deg C for 15 seconds is the standard milk杀菌 process. After the holding tube, the milk must be cooled before packaging. The ZL-20T cooling tower supports the pre-cooling stage of this HTST line. A plate heat exchanger (PHE) uses ZL-20T leaving water at 32 deg C as the cooling medium on the cold side, dropping the milk from 72 deg C to approximately 32 deg C. Flow ratio: ZL-20T delivers 16 m3/h of 32 deg C water, suitable for HTST lines processing up to 1,500 L/h of milk in the pre-cooling stage. The regeneration section of the PHE also pre-heats incoming cold milk (4 deg C) using the outgoing hot milk (72 deg C), reducing thermal load on the ZL-20T and improving overall plant efficiency.
The final cooling stage of HTST pasteurization takes milk from 32 deg C down to 4 deg C for refrigerated storage. This step requires chilled water at 1 to 4 deg C, which a cooling tower cannot produce directly because ZL-20T leaving water is 32 deg C at design wet-bulb 27 deg C. The standard configuration uses ZL-20T as the condenser cooling tower for a chiller: ZL-20T supplies 32 deg C condenser water to the chiller, the chiller uses this to remove heat from the refrigerant, and the chiller outputs 4 deg C chilled water to the plate heat exchanger for the final cooling stage (32 deg C to 4 deg C). ZL-20T plays an indirect role in final cooling by enabling chiller operation, not by directly contacting the milk below 32 deg C.
The ZL-20T integrates into dairy processing plant cooling systems:
Milk cooling: Bulk milk coolers from 35°C (cow temperature) to 4°C storage. ZL-20T supports farm bulk tank cooling at 500-1000 L capacity.
Cream pasteurization: Higher fat content requires gentler cooling profiles. ZL-20T 32°C leaving water maintains plate HX outlet temperatures within specification.
Yogurt incubation: After pasteurization, milk is cooled to 43°C for culture addition. ZL-20T control enables accurate incubation temperature.
Cheese making: Whey and curd cooling requirements vary. ZL-20T supports cheese vat cooling in artisanal operations.
Plant-wide cooling: Multiple ZL-20T units serve different processing areas (raw milk, pasteurization, packaging) with isolated cooling loops for sanitary compliance.
For dairy plants, ZL-20T SS316L upgrade is standard specification for sanitary compliance.
Brewery wort cooling uses ZL-20T SS316L upgrade for sanitary compliance:
Wort boiling to cooling: After boil, wort is cooled from 100°C to 20°C fermentation temperature. Cooling load: 500 L batch × 4.186 kJ/kg·°C × 80°C = 167 MJ per batch.
Plate heat exchanger cooling: Two-stage cooling (100°C to 50°C, then 50°C to 20°C) with ZL-20T providing cold water supply.
ZL-20T capacity: 167 MJ in 30 minutes = 9.3 kW peak per batch. ZL-20T 70 kW supports simultaneous batch cooling and fermentation temperature control.
Fermentation cooling: Active fermentation generates 5-10 kW per 1000 L fermenter. ZL-20T maintains 20°C fermentation temperature.
Sanitary design: SS316L upgrade and tri-clamp connections required for direct wort contact. CIP sanitization with 80°C hot water compatible.
For craft breweries, ZL-20T SS316L supports both wort cooling and fermentation temperature control in a single tower.
The ZL-20T SS316L upgrade complies with FDA 21 CFR for indirect food contact:
FDA 21 CFR 174-179: Indirect food contact materials requirements. SS316L stainless steel complies with FDA standards for surfaces contacting food or food packaging.
3-A Sanitary Standards: Optional 3-A certification for dairy and food processing equipment. ZL-20T SS316L upgrade meets 3-A sanitary criteria for cleanability.
EHEDG guidelines: European Hygienic Engineering and Design Group guidelines for sanitary equipment. SS316L electropolished surfaces comply with EHEDG cleanability requirements.
NSF certification: Optional NSF certification for North American food processing installations.
For food processing facility compliance, the ZL-20T documentation package supports HACCP and GMP audit requirements.
ZL-20T SS316L supports CIP sanitization cycles in food processing:
CIP cycle parameters: 80°C hot water for 30 minutes, 200 ppm chlorine solution for 30 minutes, or 121°C steam for 30 minutes (SS316L only).
Piping integration: Tri-clamp sanitary fittings enable rapid connection to CIP supply and return headers. CIP skid or portable CIP unit compatible.
Cycle frequency: Daily CIP after processing run. Weekly deep sanitization with chemical sanitizers. Monthly inspection for biofilm and mineral deposits.
Heat-up time: ZL-20T and connected piping hold approximately 500 L of water. Heating to 80°C requires 30-60 minutes with facility hot water supply.
Sanitization verification: ATP swab testing after CIP cycle confirms effective sanitization. ZL-20T SS316L surfaces support ATP testing protocols.
For food processing facility compliance, ZL-20T CIP-compatible design meets food safety modernization requirements.
Beyond process cooling, ZL-20T supports refrigeration condensers in food facilities:
Brewery glycol chiller condenser: Brewery fermenters require 0°C glycol chilling. ZL-20T provides condenser water for brewery chiller system.
Cold storage facility: 4°C cold storage rooms require refrigeration. ZL-20T supports condenser loop for cold storage chillers.
Ice bank cooling: Some dairy plants use ice banks for milk pre-cooling. ZL-20T supports ice bank refrigeration condensers.
Plate freezers: Industrial plate freezers for seafood and meat processing. ZL-20T provides condenser water for plate freezer refrigeration circuits.
Plant-wide cooling integration: ZL-20T serves both process cooling (pasteurization, brewing) and refrigeration cooling with appropriate flow distribution.
For food processing facilities with diverse cooling needs, the ZL-20T 16 m³/h flow supports multiple downstream cooling applications.

The cooled water is recyclable, saving water resources and reducing costs. There are various types, such as open and closed cooling towers. Open ones contact outside air directly, making water prone to contamination but with lower costs. Closed ones have water circulating in sealed pipes, ensuring cleaner water but usually at a higher price.
