Hot-water Immersion Unit for Disinfestation of Tropical Floral Commodities

摘要: A hot-water immersion unit was designed and tested for disinfesting tropical cut flowers foliage of quarantine pests. The main components are a 946 1 (250 gal) treatment tank, heat exchanger unit, water circulation system, temperature controller. maintained the in tank consistently at or slightly above [0 to 0.3° C (0 0.5° F)] set point 48.9° (120° F). uniform profile existed throughout tank. easily assembled, simple operate, affordable (less than $5,000). Red ginger green ti leaves treated hot 49° (120.2° F) 12 14 min, respectively, had significantly longer vase life when compared controls (p < 0.05).
