Working Principle:
Vacuum cooling captivates with its ingenious method of rapid water evaporation from selected vegetables or products within a vacuum chamber, where atmospheric pressure is astonishingly low. This process artfully harnesses energy through heat to transform water from liquid to vapor, reminiscent of boiling. In this meticulously controlled setting, water boils at significantly lower temperatures, guaranteeing superior cooling performance.
This extraordinary vacuum pre-cooling technique ingeniously absorbs the essential heat directly from the product, covering both the innate field heat and that which results from respiration. The process gracefully incurs about a 1% reduction in the product's initial water weight for each 10°C temperature decline. The elegance of this method lies in its precision, as moisture is uniformly withdrawn from all areas of the produce, effectively preventing any undesirable localized wilting.
Vacuum Cooler Features:
1. Safeguard and preserve the vibrant freshness and vital nutrients of your precious produce.
2. Remarkably extend produce preservation time, significantly enhancing shelf-life for longer enjoyment.
3. Relish in rapid, uniform cooling every cycle, taking a mere 20 to 30 minutes to achieve optimal results.
4. Efficiently suppress and eradicate bacteria and microorganisms, ensuring a pristine, pollution-free product outcome.
5. Experience minimal evaporative water loss, merely 2 to 3% of the total product weight, with no concern for localized wilting.
Vacuum Cooler Application Fields
Ideally suited for leafy greens such as lettuce and spinach. This cutting-edge method perfectly accommodates field-packed produce utilizing perforated films. Though dense vegetables like cabbage, broccoli, and carrots may require a bit longer cooling duration, the significant enhancement in shelf life is undoubtedly worthwhile.
For sensitive fruits such as strawberries and mushrooms, initiating cooling immediately post-harvest is paramount to preserving their immaculate condition and extending their usability.
