The export of grapes from India to the Australia and New Zealand is limited
due to strict phytosanitary requirements of these countries. Drosophila suzukii has
been considered as an invasion insect in these countries. Therefore these countries
demand for fumigation of grapes with CO2 and SO2 at specified concentration for
certain period besides the other pack-house protocols and export standards.
Fumigation of any food material at large scale with such hazardous gases demands
a leak-proof electronically operated fumigation chamber in present scenario. In
view of the challenge to establish a sophisticated fumigation system, the APEDA
funded a project to ICAR-CIPHET to establish a fumigation chamber and develop
process protocols for treatment of grapes. The project was focused to develop and
establish an electronically controlled fumigation chamber for treatment of grapes in
the grapes producing region and develop protocol for fumigation treatments.
The fumigation chamber was designed and then constructed at M/s Sahyadri
Farmers Producer Company Limited, Survey No. 314/1 & 314/2, A/P Mohadi,
Nashik – 422206, which is a leading company in grapes export business. The
chamber has capacity for treatment of one pallet (1500 kg) grapes at a time. The
walls and roof of the fumigation chamber are made from PUF panels and joints are
leak-proof. The chamber has two sections, one for treatment and the other for
placing the cylinders and release system. The fumigation operation is controlled from outside using electronic control panel. The gas injection and evacuation
systems are electronically operated and the levels can be varied according to the
requirement. Heaters of 2 kW are fitted inside the chamber to maintain the treatment
temperature above 16oC. All the operations of the fumigation system are controlled
by a BMCS (Building management and control system) program specifically
prepared for this fumigation system, which is touch screen operated. The details of
construction material is given and some guidelines for fabrication of higher capacity
chambers is also included in the report.
Pressurized helium leak testing of fumigation chamber was done and found
leak-proof and safe for fumigation operation. An operation manual along with
safety measures was prepared. The operation protocol was developed. Temperature
inside the chamber can be maintained above ambient. The CO2 and SO2 gas
concentrations can be maintained between 600-60000±100 ppm and 10-10000±2
ppm, respectively for 1-90 min. The pack house unit operations protocol was also
prepared. The fumigation of grapes (packed into punnets and place in CFB boxes)
with 6% CO2 for 30 min followed by fumigation with 1% SO2 for 30 min ensured
100% mortality of the adult insects. Fumigation followed by immediate precooling
and cold storage for 6-12 days ensured 100% mortality of insects and maggots and
safe for export.
This fumigation chamber can be constructed in higher capacities also with
technical guidance. All the facilities, tools, materials, equipment, sensors, software
and trained man-power are available in India. This chamber may also be used for
fumigation treatment of other fruits, vegetables, nuts, etc. as per the time and
concentration of gases required for the 100% mortality of target pests. However,
the protocol for such treatments should be developed and effect of the gases on the
quality of the products must be studied to ensure food safety.
