Component of Vacuum cooler

What is vacuum cooling?

The people at the supermarket or the consumers are the hallmark of the quality to tell that a unique process has cooled the product. The vacuum cooling process differs from conventional methods as in vacuum cooling, the cooling is achieved within the products rather than forcing to blow the cold air over them.

 

What are its applications?

As vacuum cooling is not suitable for every type of product, the one that uses it is reproachable. In general, the product with the best effect of vacuum cooling should have a leafy nature or have a large surface-to-mass ratio. Few products are Lettuce, mushrooms, celery, spring onions, broccoli, and more.

What are its advantages?

The two of the most beneficial features of vacuum cooling are speed and efficiency that are unsurpassed by any other method, especially when it is about cooling the pre-packed, boxed, or palletised products.

As already mentioned above, the small amount of water evaporated from the fresh products when kept under vacuum coolers releases less than 3% of water. Therefore, in some cases, removing water can be an advantage, but sometimes it deteriorates the fresh produce.

What are the main components of vacuum coolers?

●     Product Chamber

The size of the product chambers is supposed to be big enough to occupy the quantity for each cycle together with proper clearance to allow the badly stacked pallets or a possible future change in the stack dimensions. There is a range of chambers that accommodate single or twin-track conveyor systems. The chambers can be customized as per your need and requirements. You can choose a hinged, sliding, or vertical lift door in a manual or automatic option.

●     Vacuum Pump

The vacuum pump is used for the initial pump down of the vessel from its atmospheric pressure to the flashpoint of water. Once the atmospheric pressure has reached the flashpoint, the efficiency of the vacuum pump is limited by the size of the refrigerant pump. In general, the vacuum coolers manufacturers size the pump to reach the flashpoint in 5-8 minutes.

●     Refrigeration Plant

After the pressure has reached the flashpoint, the water starts evaporating from the surface of the fresh products. The process of evaporation helps in achieving cooling. For example, in a vacuum cooling machine, say a 1000 kg of product is cooled per cycle, then 1860 m3 of vapor would be created and will be required to pump out from the chamber.

●     Conveyor Systems

The conveyor system plays a vital role in the cycle system, especially with vacuum coolers. To achieve rapid turnaround times, vacuum cooling for fruits and vegetables offer a variety of manual or power-assisted systems.

●     Control System

The control system fitted in a vacuum cooler is sophisticated and not complicated and operates just with a one-push button to begin the cooling process. The cycle automatically stops when the temperature reaches the preset temperature. Although you can choose any mode of operation, a fail-safe circuit helps ensure that the system will automatically shut down in a safe condition if any of the monitoring devices detect any fault.

Wrapping-up

The quality of the products keeps on deteriorating upon harvesting and continues to keep on getting worse after that. In the case of vegetables, quality results from the microbiological and physiological activity in the harvested product. The deterioration that takes place in the fresh produce happens due to time and temperature. In simple terms, we can say that the faster the harvested products are cooled, the better the quality and the longer shelf life it will have. To be able to achieve this, the process of vacuum cooling is required as vacuum cooling is considered one of the best Post-harvest cooling methods. 

It helps to maintain the temperature of the product quickly and uniformly, making the products more efficient.
