Milk Quick Cooling
System
NexAgri configures plate or tubular milk-side exchangers with refrigeration equipment and controls for cooling before refrigerated storage. Standard systems cover 3–10 T/H and modular arrangements cover 15–30 T/H, sized around peak milk flow, inlet temperature and the required outlet duty.
Why Commercial Dairies Retrofit Rapid Chillers
Water pre-cooling and mechanical chilling share the heat load before milk enters storage. NexAgri coordinates the exchanger, refrigeration package and bulk-tank interface as one cooling arrangement.
Outlet Design Target
A 4°C outlet is a design target for rapid cooling before refrigerated storage. Size the duty from milk flow, inlet temperature, ambient conditions and available refrigeration capacity.
Pre-Cooling Stage
Water pre-cooling removes part of the milk’s heat load before mechanical chilling. Water temperature, flow and exchanger sizing determine the refrigeration duty left for the next stage.
Heat-Recovery Option
The heat-recovery option preheats water toward a 50°C design target, sized around refrigeration load and incoming-water conditions. Storage and boost heating complete the supply for the cleaning routine.
Cooling System Configurations
Select the cooling configuration around peak milk flow, ambient conditions and installation space.
Standard System (3-10 T/H)
For Mid-Sized Dairies
Standard 3–10 T/H systems combine a milk-side exchanger, buffer arrangements and a single-unit refrigeration package. Plate or tubular construction and the site connections are matched to the cooling duty.
High-Volume Modular (15-30 T/H)
For Mega-Dairy Operations
For the 15–30 T/H range, NexAgri combines multiple refrigeration units with the milk-side cooling circuit. The module combination is sized for peak milk flow, ambient temperature and heat rejection.
Heat-Exchange & Control Options
NexAgri configures plate or tubular heat exchangers, refrigeration equipment and controls as a complete milk-cooling system.

Total Cost of Ownership (TCO) & Planning Guide
Compare water use, refrigeration electricity, cleaning and service costs for the proposed cooling arrangement.
1. Pre-Cooling & Energy Balance
Incoming warm milk adds refrigeration duty to storage. Evaluate a two-stage cooling skid together with the bulk tank using the actual flow profile, inlet temperature and collection schedule.
A first-stage target near 20°C depends on water temperature, water flow and heat-exchanger sizing. Size the second stage for the required outlet target, such as 4°C. Compare total pump and refrigeration electricity with the existing system using the same milk load.
2. Exchanger Construction & Service
Plate systems need access to the plate pack and gaskets for service. Tubular systems need access to tube joints and connections. Include these tasks with cleaning, inspection and spare parts in the operating plan.
The SUS316L tube-in-tube option uses a welded exchange section. Service planning covers welds, connection seals, cleaning access and pressure limits.
3. Auto-CIP & Adaptive Load Sensing
Flow and temperature inputs allow the PLC to coordinate compressor staging or VFD operation. NexAgri specifies sensors, alarms, CIP interfaces and control connections within the cooling package; recovery-water heating is matched to the cleaning duty.

Direct Tank Cooling
The storage-tank refrigeration system handles the incoming milk heat load.
Staged Milk Cooling
First-stage water cooling removes part of the heat load; the second stage targets the required outlet temperature before storage.
Use the same milk load and operating schedule. Include cooling-water temperature and flow, pump electricity and refrigeration electricity.

Milk Quick Cooling System FAQs
Practical answers for dairy farms and processing facilities planning rapid milk cooling before storage.
How do I choose the right milk quick cooling system capacity?
Standard system configurations cover 3–10 T/H, with modular arrangements for 15–30 T/H. Size the complete milk-cooling circuit for the maximum hourly parlor flow, milk inlet and target temperatures, ambient conditions and available utilities.
What is included in the cooling system configuration?
Your cooling package combines the selected plate or tubular exchanger, milk pump, refrigeration equipment, sensors and controls. The proposal sets out buffer arrangements, CIP connections and the electrical, pipework and control interfaces.
How is pre-cooling water used?
Suitable water carries away part of the milk heat load before mechanical chilling. A milk-to-water ratio of 1:1 to 1:2 is a design reference; the final water flow is sized from inlet-water temperature and required heat removal, alongside water quality and any reuse plan.
Do I still need a bulk milk cooling tank after quick cooling?
Yes. The quick-cooling system reduces milk temperature before storage, while the insulated bulk tank holds milk until collection or further processing. Select both systems as one process: the cooling skid, storage volume, tank refrigeration capacity and collection interval should be reviewed together.
Can the system provide heat-recovery water for cleaning?
Refrigeration heat recovery can preheat water for suitable farm uses. Size the recovery circuit, water storage and any boost heating around the cooling load, required water volume and final cleaning-water temperature.
How is automation integrated with the milking process?
Milk-flow and temperature sensors feed the Siemens PLC, which coordinates compressor staging or VFD operation. The control package includes the HMI, alarms and connections between the milk line and refrigeration units; the proposal identifies the plant signals to be exchanged.
