Vapor Heat Treatment systems (VHT systems)


Vapor Heat Treatment System (VHT system) as the main product,

Our special heat control machine has been used around the world.


What is Vapor Heat Treatment System?

 The Vapor Heat Treatment System (hereinafter “VHT System”) is a device for steadily killing eggs and larvae of fruit fly parasitizing inside with vapor and heat without injuring of fresh fruits.


 The device operates on the following basic principle: The fruit is exposed to heat at specified temperature and humidity levels, increasing its internal temperature. So, that is able to kill the parasite while avoiding heat injury to the fruit.


 The system of equipment we provide is called the "differential pressure treatment system.” This treatment system type uses differential pressure to induce efficient circulation of vapor heat through all spaces in-between fruits so that every each individual fruit is always evenly and uniformly exposed to vapor heat atmosphere.


 Currently, almost all fresh fruits being imported to Japan on the condition of VHT are processed with differential pressure type treatment system.
