ΒΡΑΒΕΙΟ EUROPEAN BUSINESS AWARD 2012 / 2013
Polypan Group is the sole distributor of Contronics systems in Greece and Cyprus. Contronics, established in 1981, develops and manufactures ultrasonic humidifiers and related products such as Reverse Osmosis water treatment systems, humidity control units and humidity sensors.Contronics has taken part in several international developing projects. The latest series of humidifiers and our transport humidifier were awarded with the prestigious Eureka Lynx Award!
The problem: From the time of harvest, the products are subject to large fluctuations in temperature and humidity and as a result lose their freshness and end up on the shelf in a bad shape (faded, dry, with dark spots).
The supermarket, in spite of their best efforts, cannot offer quite that level of freshness. The road from the field to the shop is long.Refrigeration and cooling slows the development of bacteria but as a result draws moisture out of the product. Waste is the only option.
If the products are being exported abroad the producers have even more problems (due to many days on the road) and there are many occasions when the products are not even accepted by foreign customers, who have very strict control methods.
The solution: Contronics has the perfect solution for the preservation of products in good condition throughout the whole supply chain. In addition, in order to increase the shelf life of the products we use Phyto natural decontaminant based on citrus extracts. This prevents the development of bacteria and the spoilage of our products.
How it works
Ultrasonic humidifiers produce a fine mist of water particles of 1 micron. The water particles evaporate and withdraw evaporation energy from the surrounding air (adiabatic effect).Consequently the temperature of the surrounding air will drop. The products don’t become wet and don’t feel wet.The humidifier contributes to the cooling process and uses very little energy.
Alternatives to ultrasonic humidifiers are nozzles (spraying systems) and steam. Steam costs a lot of energy to produce (10x as much, compared to ultrasonic). The warm vapour has to be cooled again. Nozzle systems require a huge installation (compressor, high pressure pump). The nozzles are noisy. Water particles are bigger causing dripping and wet products.
Installation of Contronics machines is very simple (plug and play) and the only requirement is access to water, electricity and drainage.
They can be installed in:
- Greenhouses, cold rooms, storage and processing plants, conveyor belt
- Frigo Trucks (with our awarded travel fogger)
- Reduction of weight loss.
- Improving the quality characteristics of fruits - vegetables.
- Increase of the shelf life of final products - Reduce wastage.
