What is Vacuum Cooling?

Vacuum cooling is a technique of cooling things down to very low temperatures. The fruit and vegetable industry has been using vacuum cooling for many years. Wondering why? It’s all because of the fantastic results that it provides. Out of the innumerable options, most food industry businesses trust the process of vacuum cooling systems for food preservation. If you’re on the search to know everything about vacuum cooling systems, you’re at the right place!

Today’s blog post is all about what vacuum cooling is and everything related to it that you must know. Let’s begin!

What is Vacuum Cooling?

Vacuum cooling for fruits and vegetables is a quick evaporative method that primarily involves evaporating the product’s moisture using a vacuum. It provides faster processing time, longer product shelf life, and better product quality and safety. These have correspondingly expanded its appeal to food manufacturers.

Any porous substance with water content can be quickly cooled using vacuum cooling, which operates on the evaporative cooling principle. Due to its efficiency and great functionality in removing water from inside and outside the products, vacuum cooling is an excellent process to chill food products with high water content and significant porosity. It is the most efficient and used method for the rapid cooling of food products and it is also one of the most effective and cost-effective ways to cool and store produce, fruits, flowers, and other items.

What is the Purpose of Vacuum Cooling?

The vacuum cooling for the fruits and vegetables protects product freshness more effectively. One of the best ways to ensure fruits and vegetables have a longer shelf life is to cool them quickly. The cold temperatures might severely slow down the growth of microorganisms on the surface of the food.

With a perfect vacuum cooling machine, a container can be chilled and prepared for shipping in less than 30 minutes. The rotary vane and dry screw pumps get utilised for this application.

Compared to the available conventional cooling approach, this cooling technology’s efficiency stands the best for its purpose: cooling food items and increasing their shelf life. The industrialists call it the best method because it has brought great relief to them since the time it came into effect.

What are the Advantages of Vacuum Cooling?

Here are some advantages of the vacuum cooling system that make industrialists use it over other cooling systems:

1. Quick Cooling Rate

The vacuum pre-cooling method stands out for its quick pre-cooling speed. Even after packaging and pre-cooling, most green vegetables’ temperature can be lowered to 4-5 degrees in 20–30 minutes. On broadleaf plants, the vacuum pre-cooling effect is used widely.

2. Uniform Cooling

The moisture content in perishable products can evaporate and absorb the body’s stored field heat simultaneously due to the pressure balance at each place in the pre-cooling box, which even cools the product.

3. Minimum Use of Energy

The vacuum reduces heat input from the environment without removing the cooling unit from vacuum cooling for fruits and vegetables, resulting in low energy consumption.

4. Products Remain Clean

The perishable products remain clean since air can only enter through the openings of the chilling vacuum chamber. The products are kept at a temperature between one and three degrees by precisely controlling the absolute pressure during the cooling process.

Reasons to Purchase Vacuum Cooling

Now that you have gone through the advantages, here are some reasons to consider purchasing vacuum cooling for fruits and vegetables.

1. Dependable Design for Demanding Industrial Applications

The durable, space-saving, non-contact, long-lasting seals and dependable constant flow of the cooling system are all part of an efficient cooling system—this emphasis on reliability results in higher uptime, longer service intervals, and lower maintenance costs.

2. Enhanced Operational Efficiency and Constant Vacuum

The vacuum cooling for fruits and vegetables provides higher productivity, quicker processing, and shorter pump-down times, enhancing the operational efficiency and continuous cooling of the products.

3. Low Ownership Costs

By matching and maintaining the needed vacuum levels for the application, variable speed drive (VSD) technology improves energy usage and results in significant savings. The small footprint frees up space in utility rooms or manufacturing units.

4. Protects the Environment

With a vacuum cooling system, there is no contamination danger. It is because of the dry screw operations. It has a minimal carbon footprint and uses fewer resources than average. Additionally, quiet and slack operation enhances the entire working atmosphere in any application setting.

To Conclude,

Vacuum cooling can be a worthy addition to your industry. If you own a business that needs to preserve products like fruits and vegetables, look no more because a vacuum cooling machine is a perfect solution to increase the shelf life of your products.
