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

Sanshu's special heat control machine has been used around the world.


 Vapor Heat Treatment systems (VHT systems)

 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.

 Vapor Heat Treatment Commercial Systems

For sterilization of fresh fruit in large quantities


 These system are capable of sterilization a large volume of fresh tropical fruit in one operation.

 Currently, the commercial module type has the capacity to treat 0.5 to 5 tons.

 Various models are available for a variety of types of fresh fruit and installation location.

Vapor Heat Treatment Testing System

For sterilization tests and fruit damage tests

 This system can be installed in a test chamber as a biochemical testing system according to purpose.

The differential pressure mechanism permits the provision of a variety of environmental conditions, including temperature and humidity, with high precision; their control and maintenance; and recording of the results during the course of the experiment at any time, as needed. 

 Biochemical equipment


Installation of Biotron, temperature and humidity controlled chamber and clean room.
