摘要： A vacuum cooler for produce and the like includes a vacuum tube forming a vacuum chamber into which produce is placed. A vacuum pump lowers the atmospheric pressure while cold water is gently sprayed onto the produce. Water vapor from the produce is condensed, directed to a sump in the chamber without permitting such condensed water to impinge on the produce, and then directed through a water disinfecting chamber for reuse. The cooler includes a venting system that admits outside air into the vacuum chamber, gradually returning the chamber to atmospheric pressure, and permitting removal of produce from the chamber.

摘要： Method and apparatus for vacuum cooling field harvested produce such as lettuce includes a vacuum chamber, a partial vacuum-forming mechanism in the chamber, a water discharging mechanism in the chamber for spraying water onto the produce to cool the produce, and a mechanism in the chamber for detecting and adjusting the temperature and pressure, dynamically, to minimize undesired removal of water from the surface and interstitial tissues of the produce.

摘要： Solid materials, such as soils, containing contaminants are treated with hydroxyl radicals, in the gas phase. The hydroxyl radicals are created by hydrogen peroxide or ozone, preferably a combination of hydrogen peroxide, ozone and UV light. A decontamination unit for on-site use in the treatment of contaminated solid materials, such as contaminated soil is a totally enclosed closed-loop system.
摘要翻译： 含有污染物的固体材料如含有污染物的物质在气相中用羟基自由基处理。 羟基自由基是由过氧化氢或臭氧产生的，最好是过氧化氢，臭氧和紫外光的组合。 用于污染固体物质如污染土壤的现场使用的净化单元是全封闭闭环系统。
