Luxury Hotel Furniture Suppliers introduces that hot-air drying is a hot-air furnace for heating that is located outside the kiln and connected to the drying kiln by air inlet and return pipes. The air drying medium is introduced into the hot air furnace outside the kiln through the return air pipe for heating, and then sent back to the kiln by the blower, which is a conventional drying with double air circulation. The disadvantages of this method are low utilization rate of heat energy; high power consumption; uneven distribution of temperature and humidity in the kiln; difficult adjustment of process parameters; slow and uneven drying speed; easy corrosion of return air ducts and blowers; small drying kiln capacity. The output is higher than the cost, so it is not recommended.

This method is a traditional drying method that uses saturated steam with a gauge pressure P≤0.4MPa to heat the drying kiln through a heater to circulate the air drying medium to dry the wood. Its advantages are that the process parameters are easy to control, and the drying quality is generally better; the temperature and humidity can be adjusted in a wide range, and various materials can be dried; and it can be used for centralized heating, and the application is more common. The disadvantage is that a steam boiler is required, and the investment cost is relatively high; and the latent heat of vaporization of steam is mainly used. The condensed water is often unused due to troublesome recovery, resulting in waste and increased costs. It is mainly suitable for enterprises with large production scale or ready-made steam available, especially suitable for dry coniferous wood and soft broad-leaved wood or thin board and other easy-to-dry wood species. For small and medium-sized hotel furniture manufacturers, this method is not very suitable because of the need for expensive steam boilers.
