| Abstract/Contents: | Discusses post-harvest technologies, stating that "scientists have been researching the best ways to keep produce, including fruits, vegetables and flowers, 'fresh' after it's harvested." States that "refrigeration is one of the most effective ways to preserve plant material. Cool temperatures slow down the natural aging process of harvested produce, while inhibiting bacteria and fungi that would otherwise destroy the product." Profiles vacuum-cooling, stating that it is "often used to rapidly chill fresh produce right in the field...[and it] is basically evaporation pumped up on steroids." Details how vacuum-cooling works, stating that it "accelerates evaporation many fold by 'sucking' a little bit of water out of the produce, resulting in rapid and dramatic cooling." Relates vacuum-cooling to sod production, explaining that "sod is perishable produce with a short lifespan" and that "a large sod producer in Southern California, Southland Sod Farms...has developed a large vacuum-cooling installation to treat their tall fescue sod almost as soon as it's harvested." Reports that "the temperature of the sod dropped very rapidly during the 12-minute vacuum treatment...[and] this drop occurred not just at the edges, but also deep inside the sod stack." Also reports that "the cooling effect inside the stack lasted at least two full days; by contrast, the sod pieces at the top of the stack, which were exposed to direct sun, warmed up very quickly and followed the day/night temperature swings." Concludes that "nothing is better than transporting...sod quickly to the job site and getting it laid and watered as fast as possible. But if sod must be stored or shipped long distances, cooling may make a lot of sense." |
