Hydro Cooling

1. Rapid Cooling
   • Water has a much higher heat transfer rate than air, so hydrocooling removes field heat quickly. 
   • This helps maintain freshness and slows down respiration and ripening. 
2. Reduces Moisture Loss
   • Unlike air cooling, hydrocooling prevents dehydration because the produce is in contact with water. 
   • This helps maintain weight and crispness. 
3. Improves Shelf Life
   • Rapid temperature reduction slows microbial growth and enzymatic activity. 
   • Extends storage and market life significantly. 
4. Energy Effciency
   • Water is an efficient cooling medium, often requiring less energy compared to forced-air cooling for the same temperature drop. 
5. Uniform Cooling
   • Water surrounds the produce, ensuring even cooling regardless of shape or size. 
6. Compatible with Many Crops
   • Works well for dense or bulky produce like melons, sweet corn, carrots, and leafy greens. 

Limitations to keep in mind:

• Not suitable for produce sensitive to water (e.g., berries, mushrooms). 
• Requires clean, sanitized water to avoid contamination. 
• Initial setup cost can be high.
