4 Pallet Vacuum Cooler

4 Pallet Vacuum Cooler – CC-VC-400

The Cold Change 4 Pallet Vacuum Cooler CC-VC-400 is a high-performance industrial vacuum cooling system designed for growers, pack-houses and food processors requiring rapid cooling with greater production capacity.

Designed to accommodate 4 pallets per cooling cycle, with loads of up to 800kg per pallet, the CC-VC-400 can handle approximately 3,200kg of product per batch, depending on the product and loading configuration.

Also known as a 4 pallet vacuum chiller, vacuum pre-cooler or industrial vacuum cooling machine, the system uses vacuum technology to rapidly remove field and product heat from suitable fresh produce.

Typical cooling cycles can range from approximately 8–25 minutes, depending on product type, weight, starting temperature, target temperature, packaging and operating conditions.

4 Pallet Vacuum Cooling Applications

The 4 Pallet Vacuum Cooler provides a useful balance between compact equipment size and commercial production capacity.

For growers and packhouses that have outgrown smaller one- or two-pallet systems, a four-pallet machine can substantially increase the quantity of product processed during each vacuum cooling cycle.

Cold Change vacuum cooling systems can be configured for products including:

The cooling program can be configured around the particular characteristics of the customer’s product and production process.

How Does a Vacuum Chiller Work?

A vacuum cooler or vacuum chiller operates differently from conventional air-based pre-cooling equipment.

Four loaded pallets are placed inside the sealed vacuum chamber and the door is closed. Powerful vacuum pumps then reduce the pressure inside the chamber.

As pressure falls, the boiling point of water also falls.

A small quantity of moisture within or on suitable products begins to evaporate at a low temperature. The energy required for this evaporation is taken from the product as heat.

This allows suitable products to be cooled rapidly throughout the load rather than relying solely on cold air gradually removing heat from the outside.

For the right products, vacuum cooling can therefore provide extremely rapid and uniform post-harvest temperature reduction.

4 Pallet Mushroom Vacuum Cooler

Rapid temperature reduction can be particularly valuable following mushroom harvesting.

Fresh mushrooms can retain significant product heat, and quickly bringing the crop towards its required storage temperature can help protect quality throughout packing, storage and distribution.

The CC-VC-400 provides capacity for four mushroom pallets during each cooling cycle, making it suitable for commercial mushroom farms requiring greater throughput than a smaller one- or two-pallet machine.

Read our Vacuum Cooling Mushrooms Guide for more information about mushroom cooling, cycle times and post-harvest temperature management.

4 Pallet Vacuum Cooler for Lettuce & Leafy Vegetable Cooling

Vacuum cooling is widely used for lettuce and other leafy crops because suitable produce can be cooled rapidly throughout the load.

For commercial growers handling lettuce, spinach, leafy greens and similar products, rapid pre-cooling can reduce the time between harvesting and reaching the required cold-chain temperature.

With capacity for four pallets per cycle, the CC-VC-400 can provide a significant increase in throughput while retaining the rapid cooling advantages of vacuum technology.

Read our Vacuum Cooling Lettuce Guide and Vacuum Cooling Leafy Vegetables Guide for further information.

Broccoli, Cauliflower & Vegetable Cooling

Broccoli continues to respire after harvesting, making rapid removal of field heat an important consideration during post-harvest handling.

A commercial vegetable vacuum cooler can rapidly reduce product temperature before cold storage, packing and refrigerated transportation.

Depending on the product and application, vacuum pre-cooling can also be used for cauliflower, herbs, leafy vegetables and other suitable fresh produce.

Up to 3,200kg Per Batch

With four pallet positions and capacity for up to approximately 800kg per pallet, the CC-VC-400 can accommodate approximately 3,200kg per batch at maximum stated pallet loading.

This makes the system particularly attractive to commercial growers and packhouses looking for greater throughput without immediately moving to one of the largest vacuum cooling chambers.

Actual production capacity will depend on product weight, cooling time, loading and unloading time and the required number of cycles per hour.

Cold Change can calculate the required machine capacity around your actual daily or hourly production requirements.

Benefits of Industrial Vacuum Cooling

Depending on the product and application, vacuum cooling can provide:

Rapid removal of field and product heat
Typical cooling cycles of approximately 8–25 minutes
High throughput from a four-pallet chamber
Uniform cooling throughout suitable products
Rapid post-harvest pre-cooling
Faster transfer into cold storage
Improved cold-chain temperature management
Support for maintaining product quality
Potential extension of product shelf life
Repeatable automatic cooling programs
Reduced cooling demand on downstream cold rooms
Efficient commercial packhouse integration

Intelligent PLC Control

The CC-VC-400 can be supplied with a 12-inch touchscreen HMI and PLC control system designed to provide straightforward operation.

Operators can view the status of the cooling cycle through the touchscreen interface, while sensors and automatic controls manage key elements of the vacuum cooling process.

Different cooling programs can be configured for different products, allowing the same machine to process multiple crops or product types where appropriate.

Manual control backup can also be incorporated.

Smart Remote Monitoring

Cold Change vacuum cooling machines can be supplied with an optional Smart Monitoring System providing remote access to important machine and production information.

Depending on specification, monitored information can include:

Energy consumption
Cooling cycle times
Product temperature in and out
Service alerts
Machine alarms
Breakdown alerts
Historical operating information

Remote connectivity can also help Cold Change engineers provide technical support and assist with diagnostics.

Energy-Efficient System Design

Energy efficiency starts with correctly sizing the equipment for the application.

Cold Change can optimise the vacuum pumps, refrigeration system and control program according to the customer’s actual production requirements.

Important design considerations include:

Product type
Weight per pallet
Number of pallets per hour
Starting temperature
Required final temperature
Required cooling time
Daily operating hours
Ambient conditions
Available electrical supply

Energy-saving component and control options can also be incorporated during system design.

Refrigerant & Low-GWP Options

Refrigeration requirements vary according to application and installation country.

Cold Change can offer different refrigeration configurations and discuss lower-GWP and natural refrigerant optionswhere appropriate.

The objective is to select a refrigeration system that provides the required cooling performance while considering energy efficiency, environmental impact and applicable regulations.

Custom-Built Vacuum Cooling Systems

Not every packhouse uses the same pallets, containers or production layout.

Cold Change can manufacture custom vacuum cooling systems to suit individual applications.

Systems can be configured around:

Pallet dimensions
Product weight
Chamber dimensions
Required production capacity
Cooling temperatures
Loading arrangements
Packhouse layout
Refrigeration requirements

If your pallets, trolleys or containers differ from the standard configuration, contact us to discuss a customised solution.

4 Pallet Vacuum Cooler for Fresh Produce

Choosing the correct machine size is important for both production capacity and energy efficiency.
