What is Vapor Heat Treatment System?

 Vapor Heat Treatment is a Plant Quarantine treatment method. Our products have been used around the world anywhere phytosanitary is required for exporting of fresh fruits (ex. mango, papaya, dragonfruit) to Japan, South Korea, China, Australia, New Zealand, EU, and elsewhere. 

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

 The system operates on the following basic principle: 

 The fruit is exposed to heat at specified temperature and humidity levels, increasing its internal temperature. As a result, parasites are killed while heat injury to the fruit is avoided.

 The system of equipment we provide is called the "differential pressure treatment system.” Treatment systems of this type use differential pressure to induce efficient circulation of vapor heat through all spaces in-between fruits so that each and every individual fruit is continuously, 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 a differential pressure type treatment system.


 Our VHT system has large market share in the world!
