Milk Quick Cooling
System
Size staged milk cooling for the peak flow from your parlor. NexAgri offers 3–10 T/H standard skids and 15–30 T/H modular systems; a 4°C outlet target and the energy balance are evaluated against inlet temperature, water supply and refrigeration duty.
Why Commercial Dairies Retrofit Rapid Chillers
Pre-cooling and mechanical chilling can share the heat load before milk enters storage. Review the duty of the skid and bulk tank together.
Outlet Design Target
A 4°C outlet is a design target to assess against milk flow, inlet temperature and available cooling duty. Cooling supports the milk-handling process; it does not determine somatic cell count or milk acceptance.
Pre-Cooling Stage
Suitable water can remove part of the heat load before mechanical chilling. The contribution depends on water temperature and flow, exchanger sizing and pump energy; calculate savings for the proposed operating schedule.
Heat-Recovery Option
The recovery option can supply warm water toward a 50°C design target where refrigerant duty, inlet water and flow allow. Confirm required volume, storage and any further heating needed for the cleaning process.
Chiller Skid Configurations
Select the capacity tier that matches your milking parlor's maximum hourly flow rate.
Standard Skid (3-10 T/H)
For Mid-Sized Dairies
An integrated module with a tubular exchanger, buffer tank and single-unit chiller on a stainless steel frame. Match the 3–10 T/H range to peak parlor flow, then define water, power, piping and commissioning requirements.
High-Volume Modular (15-30 T/H)
For Mega-Dairy Operations
The 15–30 T/H modular range uses multiple remote condensers, with 3x 20HP as a listed configuration example. Size the array from actual peak flow, ambient temperature and heat-rejection conditions, rather than stall count alone.
Engineering Deep Dive
The listed configuration combines SUS316L tubular exchange with PLC controls and refrigeration equipment. Confirm component selection, operating limits, alarms and operator tasks in the project specification.

Total Cost of Ownership (TCO) & Planning Guide
Evaluate operational expenditures (OpEx) and risk mitigation factors before finalizing your cold chain layout.
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. Tubular Construction & Service
Gasketed plate exchangers require gasket selection, inspection and replacement suited to the process. Compare their service requirements with the proposed tubular design using the cleaning chemistry, pressure and maintenance routine.
The described welded tube-in-tube exchange section has no internal plate-pack gaskets. System connections, weld integrity and pressure limits still require inspection; define cleaning and maintenance access for the complete skid.
3. Auto-CIP & Adaptive Load Sensing
The listed Siemens PLC configuration can use milk-flow and temperature inputs to control compressor staging or VFD operation. Specify the sensors, control interfaces, alarms and CIP sequence; recovery water needs to meet the cleaning temperature and volume requirements.

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?
Size the system against the maximum hourly milk flow from the parlor, not only the daily volume. This page presents a 3–10 T/H standard skid for mid-sized dairies and a 15–30 T/H high-volume modular configuration for larger operations. Confirm peak flow, milk inlet temperature, required outlet temperature, ambient conditions and the available electrical supply for the final selection.
What is the difference between a tubular and a plate heat exchanger?
The configuration on this page uses a tubular heat exchanger in a compact skid. Heat-exchanger selection should be based on the milk flow, water quality, cleaning routine, pressure requirements and service preference. Review the full process arrangement rather than choosing only by the exchanger type.
How is pre-cooling water used?
Where suitable water is available, pre-cooling can remove part of the milk’s heat load before mechanical chilling. The page indicates a first-stage milk-to-water ratio of 1:1 to 1:2 as an operating basis. Confirm water temperature, flow, quality, recovery or reuse plan and local availability for the final design.
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?
The page describes a thermal-recovery arrangement that can capture heat from the refrigeration circuit to provide warm water for suitable farm uses. The final water temperature, volume and connection arrangement depend on the refrigeration configuration, operating load and the site’s cleaning-water requirements.
How is automation integrated with the milking process?
The skid can be configured with flow and temperature monitoring plus staged chiller control to match the milk flow coming from the parlor. Provide the parlor’s peak output, pipeline routing, voltage and control requirements so the final control and connection scope can be defined.
