Working Principle:
Vacuum cooling is a captivating technology that remarkably speeds up the cooling of select vegetables and products by leveraging the natural process of rapid water evaporation within a vacuum chamber. In this low-pressure environment, water transforms into vapor at astonishingly low temperatures, much like boiling, but under controlled conditions. This transformation efficiently extracts heat, ensuring the produce achieves optimal cooling levels with precision and care.
This extraordinary vacuum pre-cooling method ingeniously draws the necessary heat directly from the produce itself, including both inherent field heat and the heat generated by respiration. Notably, for every 10°C reduction, the product loses only about 1% of its weight in water. The elegance of this technique lies in its ability to uniformly extract moisture from all areas of the produce, thereby eliminating any risk of localized wilting and maintaining the integrity of the product.
Vacuum Cooler Features:
1. Maintain the rich, vibrant freshness and crucial nutritional elements of your produce, ensuring they're as delightful as the moment they were picked.
2. Dramatically extend the preservation period while significantly enhancing the shelf-life of your produce, allowing it to stay fresh and appealing longer.
3. Enjoy the benefit of rapid, even cooling with each cycle accomplished in a swift 20 to 30 minutes, ensuring efficiency and quality in every batch.
4. Combat bacteria and microorganisms effectively, ensuring your produce remains pure and pollution-free for safe consumption.
5. Experience minimal evaporative water loss, limited to just 2 to 3% of the total product weight, effectively preventing any concerns about localized wilting or quality degradation.
Vacuum Cooler Application Fields
Ideal for nurturing the freshness of leafy greens like lettuce and spinach, this method shines with field-packed produce wrapped in perforated films. Denser vegetables such as cabbage, broccoli, and carrots may require marginally more cooling time, but the resulting enhancement in shelf life makes it a worthy investment.
For delicate fruits like strawberries and mushrooms, initiating cooling shortly after harvest is crucial to preserve their pristine condition, thereby extending their usability and ensuring they reach consumers in peak form.
