Faithful to its leader’s reputation, Adalia group Inc. is the owner of the Adalia Deep Probing technology. This proven fumigation method, fast and efficient allows grain bins and ship holds fumigation without having to proceed to any grain transfer.

At the finest point of technology, Adalia is able to perform various analysis and controls permetting to act adequately in any situation of actual or potential infestation.

The Adalia group inc. offer to its clients a wide range of specialized and customized services .

First Canadian company to use the "J-System Fumigation" re- circulation method in Canada, Protech has mastered the installation of those systems.

This technique, based on the principle of the closed loop ensures an excellent gas distribution and is more than appropriate when we are faced to low temperature conditions and limited exposure time.

This procedure requires that the re-circulation system, composed of special fans and gas conducts, be installed prior to the grain being loaded in the ship holds or bins.

Adalia uses patented techniques to recover the dusts and residues created by the Aluminium Phosphide reaction at time of fumigation.

In deed, the use of residue recovery systems are prescribed when fumigating processed products or to answer a contractual demand from the importing country.

Technology "Deep probing", recognized and recommended by the Canadian Grain Commission was developed and perfected by Mr Denis and Guy Bureau and is exclusive to Adalia Group Inc.

It allows quickly and effectively fumigate very large batches of grain infested with insects and pests that are already loaded on board merchant ships.

The effectiveness of the technique lies in an even distribution of fumigant in the grain mass, which diminishes the time Exposure necessary. This method is much less prone to gas losses due to leaking vessels. It's also works with the grain temperature, thus ensuring the maximum effectiveness of the treatment.

The proper distribution of fumigant is essential for the complete eradication of insect pests. This technique provides a success rate of 100%, which is essential to the issuance of a phytosanitary certificate by the Canadian government.

Description of the method

The technique that has been designed and developed by Adalia Preventive Services Ltd., Canada and involves a technology that makes it possible to fumigate high volumes of grain from 1,000 to 100,000 tonnes or more without moving the grain. This efficient and safe technique allows for rapid distribution of the aluminium phosphide (ALP) fumigant in solid or gaseous form, through the mass of grain.

System Components

The system is composed of 3 elements (Fig. 3).
1. The Platform, constructed of aluminium with hydraulic or mechanical propulsion which reduces the physical effort and increases probe penetration.
2. The Probe. Two types of probe have been designed. The first is made of aluminium, ~ 2 inches (50 mm) in diameter, for very deep fumigant application. It can also be connected to a re-circulation system. The second is made of plastic, ~ 3 inches (75 mm) in diameter, and is used for silos and ship fumigation with recirculation. Both probes have a special head design to maximize performance.
3. The Vacuum system. This enables the probe to penetrate very deeply without too much stress, and when combined with the hydraulic system of the platform enhances the system’s performance.

When the probe has reached the desired depth, the fumigant tablets or pellets are then gradually discharged as the probe reverses upward and out of the grain (Fig 4).

Silo fumigation using the deep probe and solid aluminium phosphide

Table 4 and Fig 5 present the results of the fumigation of silo No. 423 in the port of Montreal. Capacity of this silo is about 800 MT or 1,390 m3, and with a depth of 30.5 m. The dosage applied was ~ 1.44 g/m3, of PH3 and the grain temperature was ~18°C.

The Aluminium phosphide formulation, (pellets), was applied to the grain between depths of 2 m to ~ 18 m below the surface. The experimental results reveal the movement of PH3 in the silo and demonstrate that lethal concentrations were achieved throughout the full depth of the bulk.

Application using re-circulation

The probe can also be connected to a re-circulation system for faster and residue-free fumigation; in this case the fumigant will be applied on top of the grain either as aluminium phosphide in a solid formulation, or possibly in the future with PH3 from a generator, or cylinders such as ECO2FUME. ECO2FUME is a cylinderised mixture of 2% PH3 and 98% CO2 that has been developed and marketed in Australia and the USA. The mixture is used in Siroflo® and Sirocirc® systems for fumigation of grain in silos and flat stores in Australia, Cyprus, USA, China, New Zealand and in some other countries. Trials with ECO2FUME for fumigation of grain in-transit have been carried out in Canada (Fields and Jones 1999).

Ship fumigation

Re-circulation has been developed and used for efficient fumigation of high volumes of grain for many years (Degesch J System). Normally this technique involves fitting the re-circulation system before the grain is loaded in to the silo or ship hold. The new 'Deep Probing' technology allows effective treatment to be carried out after loading has been completed either by inserting solid aluminium phosphide throughout the full depth of the cargo (as previously described) or by a variation of the re-circulation method which is in development. It consists of inserting probes after loading is completed and linking them to a re-circulation system (Fig. 5). The method is highly effective where extreme conditions are involved such as in short transit times or for quarantine fumigation. This new technology will be used in conjunction with one of the new PH3 generators or with PH3 from cylinders. The development of this technology is on-going. (D. Bureau - Canada)
