The company is on the market since 1980. The main office is in Northern Greece, with branches in other cities, including Volos, Thessaly. The company is interested to provide industrial heat treatment in food processing plants, flour mills, warehouses and storage structures (bins/silos) in Europe and Asia. Heat Treatment Applications Include:
• Food processing plants
• Pasta, cereal, bakeries, baby food, pet food
• Milling industry
• Flour mills, rice mills, wheat mills, rye mills
• Storage structures
• Bins & silos – concrete and steel
•Organic processing plants and storages
In the process they are able to use
1. Electrical equipment
2. PLG equipment
3. A combination of the above
The company performs both partial* and full facility treatments. Partial, spot treatments are suited to heat treat partial areas of a structure with high insect infestation levels. Entire facility heat treatments eliminate possibility of insect migration and cross-infestations and get rid of residual insect populations resident in the facility. Essentially, heat treatment is a structural treatment and is not recommended for commodities/product as the latter are inherently good insulators or bad conductors of heat. Therefore, the product/commodities/flour/grain has to be moved out prior to commencement of heat treatment. Heat is an effective tool in multiple strategies that are employed under the IPM (Integrated Pest Management) practices.
The three stages of procedure are:
• Heating up
For most insects the optimum developing and reproduction temperature is between +15°C and +35°C. At temperatures above approximately +45°C the pests, including their eggs and larvae, are killed within a few hours, because they cannot reduce their body temperature by perspiring and their own body protein and their enzymes coagulate.
The heating of all air in the building up to 50–60°C is achieved slowly. This way the building and the installations are not damaged by the heat. Producing a homogenous and economical air circulation is a must. An optimal air distribution is achieved after systematic case studies.
• Holding the temperature
The necessary temperature of 50–60°C is held over 8–18 hours to reach an adequate influence of temperature inside machines and in inaccessible hollows as well.
The expandable, wireless temperature monitoring system includes a laptop installed with proprietary temperature recording software, receiver, repeater and wireless temperature transmitters/sensors. The real-time temperature monitoring helps identify hot and cold spots in the treated area as well as regulates and controls hot air distribution. Comprehensive graphical temperature charts for the entire duration of a heat treatment are provided to the client along with the final report of the heat treatment.
The temperature can also be controlled easily with an infrared control pistol. The positions and blowing directions are modified accordingly. By doing this a disadvantageous (in terms of heat treatment) room geometry as well as shieldings by fixtures and installations can be compensated.
The heaters are turned off and the air, the installations and the building reach their normal temperature again so slowly that no heat tension damage is caused.
For a single room(a hotel room) requires approximately 24 hours, whereas a whole building with several floors needs to be treated for at least 48 hours.
The energy consumption is influenced by different factors (about 2–4 kWh per m³ space).
Two possibilities of partial treatments.
1.If the machines, that need to be treated, are not fixed permanently, they can be transported into a smaller room and be heated up there.
2.The other possibility is that the room is separated by polythene foils. Then only one part needs to be heated up.
