VAPOR HEAT TREATMENT

When importing tropical fresh fruit such as papaya, mango, mangosteen, lychee and pitahaya from overseas for commercial purposes, sterilization for fruit flies is compulsory under the Plant Quarantine Act. Good Life factory has used vapor heat treament system which is imported 100% from Japan to process the fruit exported.

FEATURES OF THE VAPOR HEAT TREATMENT SYSTEM

1.      Sterilization is performed without using chemicals, so there are no harmful effects on human health, and the quality of the fruit is assured. This system helps to protect consumer health while also preserving the global environment.

2.      Treatment is performed in saturated vapor, so transpiration of water is prevented and there is no shrinkage of the fruit skin or loss of heat through vaporization.

3.      When used on fruit at nature temperatures, high-temperature vapor greatly improves treatment efficiency, as condensation increases the surface area treated. The result is highly effective insecticidal treatment.

4.      The differential pressure mechanism involves forced supply of heat vapor, and achives superior temperature and humidity distribution, whereby large volumes of fruit can be sterilized in a single process with high reliability.
