Wood dryer, wood drying and dehumidification

Wood dryer, wood drying and dehumidification machine to handle news information Wood is commonly used as furniture wood products, building materials and decorative materials. Nowadays, with the rapid development of global science and technology, the demand for wood in various industries is increasing, but the wood resources are very limited. How to solve the contradiction between supply and demand of wood resources has become an urgent topic. The development and utilization of fast-growing wood came into being. Fast growing wood has a fast growth rate, a short cutting cycle and a rich stock, which can effectively solve the shortage of wood resources. However, fast growing wood has many inherent defects, such as low strength, easy deformation and cracking, poor permeability, etc

Wood drying is a necessary link in wood processing and storage, which can improve the dimensional stability of wood and make fast-growing wood have better quality to make furniture, building materials, plates and other wood products. However, it is often difficult to achieve the best drying quality by using a single wood drying method, and even some fast-growing wood, such as poplar and eucalyptus, are prone to shrink and crack during the drying process. The traditional wood drying method also has a lot of waste in energy utilization, which does not meet the needs of today's green industry. Wood drying pretreatment is an effective way to reduce wood drying defects and improve wood drying quality. Now let's introduce wood drying pretreatment in detail

What is wood drying pretreatment? Wood drying pretreatment refers to pretreatment before wood drying to improve wood permeability, shorten wood drying cycle and ensure drying quality. At present, common pretreatment methods include hydrothermal pretreatment, microwave pretreatment, freezing pretreatment, steam blasting pretreatment, compression pretreatment and ultrasonic pretreatment. Hydrothermal pretreatment of wood refers to the use of water or other chemical solutions to water boil the wood for a certain period of time to soften the wood, reduce internal stress, reduce drying shrinkage difference, improve dimensional stability, and effectively reduce the cracks and deformation of wood during drying

In the wood processing industry, traditional coal fired hot air stoves were used for wood drying in the past, but this has caused serious environmental pollution. Under the supervision of the relevant government policies to reduce coal consumption and limit coal consumption and the environmental protection department, "coal to electricity" has become a general trend. Some production drying methods with potential safety hazards and environmental pollution problems have been comprehensively prohibited. Some advanced drying methods, such as steam drying and vacuum drying, can improve the quality and shorten the production cycle at the same time. However, these methods have large investment and high operating costs, which cannot reduce the cost of drying to a lower level and are not suitable for promotion. Which drying method and equipment should be selected for new wood drying? How to transform the wood drying room in line with the environmental protection policy, with good drying effect and low operating cost, is a problem that wood processing enterprises should carefully consider

Many people in the drying industry must have a deep feeling about dehumidification in the drying room during the wood drying process - it's too difficult! Its difficulty is not to force out the water in the materials, but to discharge the water at a low cost. In the past, the hot and humid air in the drying room and drying room was forced out through the fan; In this way, the heat in the room will be discharged out of the room. Therefore, dehumidifiers with super dehumidification capacity have undoubtedly become the most simple and effective way to remove moisture in more and more drying rooms; However, the temperature in the general drying room should be increased to 40 ℃, or even above 50 ℃; The working environment temperature of conventional refrigerated dehumidifier is 5-38 ℃. If the temperature exceeds 38 ℃, the dehumidifier will be shut down due to automatic protection, and dehumidification cannot be carried out

For the demand of energy-saving dehumidification and drying in drying rooms and drying rooms, electrical appliances are specially developed_ G wood dryer and Parkoo series heating, drying and dehumidifying integrated machine (applicable to dehumidification in the environment where the indoor temperature is higher than 38 ℃ but lower than 55 ℃); It can not only quickly remove the moisture in the drying room, but also effectively control the humidity in the drying room during the whole drying process, so as to greatly accelerate the drying speed, effectively improve the utilization rate of the drying room and the drying quality. The overall quality of wood has reached a stage, and its advantages are self-evident.! Welcome to inquire about the details of wood dryer and wood dehumidifier
