It is a newest generation wood drying equipment and a result of design combining high frequency medium heating technology and vacuum cryogenic dehydration technology, greatly reduced drying time. This equipment adopts PLC programming control, drying chamber equipped with 80 mm thick thermal insulating layer and inside & outside two sets stainless steel condensation system, it is more convenient to choose lumber drying procedure and applicable for drying all kinds of wood. The Main control valve adopts pneumatic valve technology, this technology have advantages like steady, long serve life and low failure rate. The main advantage of our wood drying equipment: short drying cycle, super quality, cost effective and Eco-friendly.
High Frequency Generator Heating Principle
HF generator is the core of dielectric heating equipment. It applies three phase alternating current to form frequency oscillation electric field .Under this high frequency electric field, the molecules like water .glue or PVC will be polarized and form two poles. The electric field will change pole rapidly meanwhile all the molecules will also move in very high speed. The friction and impact among molecules can make material get heated in short time. Then the water will be vaporized, glue becomes solid and PVC gets softened rapidly.
High Frequency Advantage
1) Fast speed and high efficiency When HF starts,the molecules in the dielectric material will be polarized in very short time and heated.HF power only heat polar molecules.It will not heat dielectric material.HF heating is 3-5 times faster than hot steam.So it can save the power and improve the efficiency. 2) Uniform heating High frequency heating is dielectric heating.It forms electric filed with positive and negative pole.HF power can penetrate material deeply.The waster or glue molecules in the material will get heated themselves by friction among molecules.In this way,they get heated from the core material,much more uniformly. 3) Good applicability High frequency heating can heat kinds of thickness material,such as 2-3mm venner surface lamination,1000mm thick engineered wood gluing.And different frquency can meet different material requirement.13.56MHZ is suitable for PVC heating and gluing 27.12MHZ is good for line production . 4) Strong controllability High frequency heating is easy control and suitable for automatic production.Take HF edge gluer for example,HF can equip well with hydraulic system,electrical system can finish the whole process together.It can also well cooperate with last procedure. 5) No damage of wood
In the vacuum environment, moisture can evaporate at lower temperatures ,so vacuum cryogenic dehydration technology avoid high temperature to damage wood . 6)Envirnoment friendly HF heating doesn't need boiler.There is no dust,no fog,no pollution.DAXIN's products accord with national standard of radiation.
