The present invention relates to oxidative thermochemistry that modifies the hydrophilic and hydrophobic properties of organic substances, especially natural organic substances, to prepare a new class of hydrophobic lipophilic products and a new class of hydrophilic lipophilic products. Regarding the drying process. The process involves moistening and heating the raw material in a thermochemical convection device or kiln equipped with a gas distribution system in an oxidizing medium for a predetermined time. The efficiency of the treatment is improved by pre-treating the raw materials, for example by boiling in water, dipping in acidic or alkaline solutions, by mechanical swelling, by adding volatile reagents and by freezing. There are cases. One unique pretreatment with the raw material carbonate or bicarbonate gives both hydrophilic and lipophilic functional products. A series of hydrophobic lipophilic and hydrophilic lipophilic products, made from different natural substances under various oxidative thermochemical drying processes, have different properties, cheap, efficient and biodegradable It is environmentally harmless and is widely useful. |
