Wooden pallets and wooden crates are long-standing packaging products. They are characterized by their simple construction, high strength, readily available materials, durability, elasticity, ability to withstand impact and vibration, and relatively low cost. Wooden packaging is indispensable in modern logistics, storage, and various manufacturing enterprises, with wooden pallets being the most common. Because wooden pallets and crates are made from solid wood or plywood, and since wood itself contains moisture, drying wooden pallets and crates is particularly important.

　　1. Since water evaporation primarily occurs on the surface of the material being dried, the size of the drying surface area of the wooden pallet plays a crucial role in the drying process. Drying efficiency is directly proportional to the size of the drying surface area. The thicker the material being dried, the smaller the drying surface area, and the slower the drying process; conversely, the thinner the material, the faster the drying process.

　　2. Drying Speed

　　Drying should be controlled at a certain speed. During the drying process of wooden pallets, surface moisture evaporates quickly, and then the internal moisture diffuses to the surface and continues to evaporate. (fumigation-free wooden crates) If the drying speed is too fast or the temperature is too high, the surface moisture evaporates too quickly, and the internal moisture cannot diffuse to the surface in time, causing surface particles to stick together or even melt and form a film, which prevents the diffusion and evaporation of internal moisture, resulting in incomplete drying and a falsely dry phenomenon of being dry on the outside and wet on the inside, causing the material to deteriorate during long-term storage.

　　3. Drying Methods

　　During the drying process of wooden pallets, the material being dried can be in a static or dynamic state. In an oven or drying room, the material being dried is static, the drying surface area is small, and therefore the drying efficiency is poor. If the material being dried is in a tumbling or suspended state, such as in fluidized bed drying, the particles are separated from each other, increasing the drying surface area and thus the drying efficiency.
