That is because OPTIMONIA closed system dryer uses steam and hot air energy.
Once taken, air constantly circles through hot and cold chamber. In hot chamber, where fruit is being dried, hot air is extracting steam from fruit. Now, full of steam, hot air enters cold chamber, in which steam is being converted into water, thus returning to the system all the heat which was taken from hot chamber. That’s how closed system dryer uses energy received from steam, which reduces electricity consumption several times and saves money.
Steam is highly rich with energy (first steam engines have powered trains using that energy). OPTIMONIA ”CS’” dryer is using that energy like a free source, while open systems waste it which is, based on todays prices, inadmissible.
Using OPTIMONIA ’’CS’’ dryer you can save over 100 000 kWh of electricity per year on the 500 kg of fresh plum capacity (32.4 m2). With bigger capacities these differences become more significant and quickly return the investment.
