In recent years, with the continuous improvement of social and economic level and the improvement of people's living standards, people's requirements for the floor are getting higher and higher. The floor is required not only to be simple and practical, but also to meet the requirements of health and environmental protection. Due to the shortcomings of environmental protection, economy and non product defects, various floors based on traditional artificial boards have been gradually replaced by bamboo and wood flooring products. Bamboo and wood flooring is more textured; Therefore, for bamboo and wood, it is a better environment-friendly flooring material
Bamboo and wood flooring, namely bamboo and wood composite flooring, is a composite regeneration product of bamboo and bamboo and wood flooring. Its panel and bottom plate are made of superior bamboo, and its core layer is mostly bamboo flooring such as fir and camphor wood. Its production and manufacture must rely on sophisticated machinery and equipment, advanced science and technology and standardized production process flow. After a series of 40 complex processes, such as anti-corrosion, anti-corrosion, moisture-proof, high pressure, high temperature, gluing and rotary milling, it can be made into a new type of composite flooring. However, bamboo and wood flooring contains more water. In the process of making flooring, if the bamboo and wood flooring is not dried, it will shrink and swell. Uneven drying shrinkage and wet expansion of bamboo and wood flooring will cause deformation and even cracking of bamboo and wood flooring
The moisture in bamboo and wood flooring provides a suitable environment for the growth of bacteria and parasites, increases the possibility of bamboo and wood flooring being corroded, and seriously affects the appearance and service life of the flooring. Therefore, the bamboo and wood floor used for making the floor must be dried. The drying process of bamboo and wood flooring directly affects the quality of bamboo and wood flooring. Inappropriate drying process will result in a decline in the grade of bamboo and wood flooring, and in serious cases, it will cause the loss of use value of bamboo and wood flooring. The forest resources in China are becoming more and more tense, and the waste of bamboo and wood flooring resources caused by improper drying process is becoming more and more serious, which directly affects the ecological environment and sustainable development of China
At present, the current bamboo and wood floor drying equipment is to dry the bamboo and wood floor at high temperature by burning coal or charcoal to generate heat, or by using electric heating to generate heat. It mainly uses the principle of moisture transmission, that is, the principle of moisture gradient. Specifically, the moisture in the bamboo and wood floor tends to move from the part with high moisture content to the part with low moisture content, However, the principle of temperature gradient, which is the heat and moisture transfer characteristic of water in bamboo and wood flooring, has not been used. The so-called temperature gradient principle refers to that the moisture content in bamboo and wood flooring tends to move from the part with high temperature to the part with low temperature. In the traditional drying process of bamboo and wood flooring, the moisture content gradient and temperature gradient of bamboo and wood flooring are in a reverse state
For example, during the drying process of bamboo and wood floors, the air inlet and outlet of the bamboo and wood floor drying room are open when moisture is discharged. In order to ensure room temperature, the heater is always in the automatic heating state. The circulating air flow generated by the fan continuously transfers the heat emitted by the heater to the surface of the bamboo and wood floor, so that the surface temperature of the bamboo and wood floor is higher than the center of the bamboo and wood floor, At this time, the temperature gradient of bamboo and wood floor is high outside temperature and low inside temperature; The circulating air flow of the fan constantly takes away the moisture on the surface of the bamboo and wood floor. The moisture content in the center of the bamboo and wood floor is higher than that on the surface of the bamboo and wood floor. Therefore, the moisture content gradient of the bamboo and wood floor is low external moisture content and high internal moisture content
According to the temperature gradient principle and moisture content gradient principle of bamboo and wood flooring, the moisture in bamboo and wood flooring tends to flow from the part with high temperature to the part with low temperature, and from the part with high moisture content to the part with low moisture content. Therefore, the drying process of bamboo and wood flooring is carried out under the reverse state of the two gradients. The effect of moisture content gradient of bamboo and wood flooring should be greater than that of temperature gradient, The function of moisture content gradient is to overcome the tendency of water moving from outside to inside due to temperature gradient on the one hand, and to move water from inside to outside due to temperature gradient on the other hand. However, the greater the moisture content gradient of bamboo and wood flooring, the greater the internal stress it bears. When the internal stress is too large, bamboo and wood flooring will crack in the early drying stage, and will deform in the late drying stage. In the middle drying stage, improper treatment will also cause bamboo and wood flooring to crack
Therefore, when using the traditional drying process to dry bamboo and wood flooring, it is not allowed to sharply increase the temperature and reduce the humidity, otherwise it will cause drying defects of bamboo and wood flooring. In recent years, in response to the government's "two mountains" theory (green water and green mountains are golden mountains and silver mountains), under the active leadership of the local municipal party committee and government and the promotion of the national policy of "replacing coal with electricity", more and more bamboo and wood floor furniture has decided to vigorously rectify the original high pollution and low energy efficiency boiler burning firewood and coal, and replace all of them in the drying room with_ G bamboo and wood flooring dryer and Parkoo series heating, drying and dehumidifying integrated machine are used to dry and dehumidify bamboo and wood flooring, which has put the "green water and green mountains" action in place and brought great economic benefits to bamboo and wood flooring enterprises

To sum up, the floor made of natural wood will consume a lot of trees, leading to a significant reduction in forest resources and destruction of the natural environment on which we live; For this reason, people will use bamboo and wood flooring to replace ordinary wood boards. Bamboo and wood flooring has a natural and beautiful appearance, strong toughness and elasticity. Therefore, people will produce bamboo and wood flooring in large quantities. However, bamboo and wood flooring needs to be heated and dried to a certain extent after the board is formed to remove the moisture contained in it, so as to ensure that the board will not be deformed and moldy, and also play an aesthetic role; However, due to the characteristics of bamboo and wood flooring itself, excessive water loss during the drying process will cause the drying crack of bamboo and wood flooring, thus affecting the quality of bamboo and wood flooring
Bamboo and wood floor dryers on the existing market generally use simple mechanical heating principle, which has low utilization rate of heat energy. In addition, they often use pure heating methods to dry, and do not have the function of moisture removal, so the drying effect is not good. In addition, in this process, due to the strengthening of heat, the bamboo and wood flooring containing water generally dried and cracked, affecting the actual processing quality of bamboo and wood. In the process of low-temperature heating, the drying effect was not ideal and could not meet the high requirements of the enterprise
