The article presents a modification of the existing mathematical model to calculate energy consumption during conventional drying process. Apart from energy consumption, the model permits to estimate the time of high-temperature drying process. The drying medium is air and superheated steam mixture. The obtained calculation results were compared with conducted experimental tests of drying square-edged sawn sapwood timber (Pinus sylvestris L.). The pine sawn wood samples were dried according to three different drying modes, namely mild, normal and intense. The experiments were performed in a semi-industrial scale drying chamber. On the basis of the experimental research available, existing mathematical models of drying wood have been improved. The developed model included the following changes: a different drying time for each mode and type of drying medium (moisturized air or air and superheated steam mixture). The use of an intensive drying mode significantly reduced the drying process time. The developed mathematical model revealed that the energy consumption of the drying process increases with the intensity of the mode used.

本文提出了对现有数学模型的修改，以计算常规干燥过程中的能耗。除了能耗之外，该模型还可以估算高温干燥过程的时间。干燥介质是空气和过热蒸汽的混合物。将获得的计算结果与干燥方木锯边材（樟子松）进行的实验测试进行比较L.）。根据三种不同的干燥模式，即温和，正常和强烈，将松木锯材样品干燥。实验在半工业规模的干燥室中进行。根据现有的实验研究，现有的干燥木材数学模型已得到改进。开发的模型包括以下更改：每种模式和类型的干燥介质（潮湿的空气或空气和过热的蒸汽混合物）具有不同的干燥时间。强化干燥模式的使用显着减少了干燥过程的时间。发达的数学模型表明，干燥过程的能耗随所用模式的强度而增加。
