Working Principle:
Experience the marvel of vacuum cooling, an innovative process that capitalizes on the fascinating principle of rapid water evaporation from select vegetables or products housed within a vacuum chamber, where atmospheric pressure drops to extraordinarily low levels. This transformative method utilizes energy in the form of heat to convert liquid water into vapor, akin to an accelerated boiling process. Within this sophisticated setting, water begins to boil at significantly lower temperatures than usual, ensuring that cooling is both swift and remarkably effective.
This extraordinary vacuum pre-cooling process ingeniously draws the requisite heat directly from the product itself, addressing both the intrinsic field heat and the additional heat produced by respiration. This operation results in a mere 1% reduction of the product's initial weight in water content for every 10°C decrease in temperature. The true beauty of this method is its consistent uniformity, where moisture is extracted evenly across all areas of the produce, effectively preventing any unwanted localized wilting and maintaining the produce's optimal state.
Vacuum Cooler Features:
1. Preserve the vibrant freshness and retain the essential nutritional value of your produce with unparalleled efficiency.
2. Extend the preservation period substantially and significantly enhance the shelf-life of your products.
3. Benefit from rapid and uniform cooling in a remarkable cycle that completes within just 20 to 30 minutes.
4. Effectively suppress and eradicate bacteria and microorganisms, ensuring an impressively clean and pollution-free outcome.
5. Experience minimal evaporative water loss, ranging only between 2 to 3% of the total product weight, with no concerns of localized wilting.
Vacuum Cooler Application Fields
Ideally crafted for leafy greens such as lettuce and spinach, this method also excels with field-packed produce using perforated films. While denser vegetables like cabbage, broccoli, and carrots may necessitate slightly longer cooling durations, the substantial enhancement in shelf life justifies the wait and promises exceptional results.
When dealing with delicate fruits like strawberries and mushrooms, it is crucial to initiate cooling shortly after harvest to preserve their immaculate condition and significantly extend their usability.
