High frequency generator 1.Introduction: High frequency generator named radio frequency generator also. It is the core part of high frequency machinery. Different frequency- 6.78mhz, 13.56mhz, and 27.12mhz can be widely used for woodworking (plywood bending, glue curing, timber drying), grain worm killing, freezing meat melting, and environment protection field.  High frequency generator generates electromagnetic fields between two electrodes through three phase alternating current. In this field, water and glue molecules are polarized - rotated - heated by friction.  high frequency heating is not like conductive heating, which heat material step by step, but help object heated themselves by friction. This is called high frequency dielectric heating-quickly, efficiently and evenly. Besides, there are more advantages in high frequency heating: 1). Easy to control: once cut off power, no heating anymore; once power on, heating works wholly. 2). Low heating loss, energy saving. 3).Environment friendly: high frequency is clean power, dust free. 4).Hf power can kill worm and bacteria in the material like timber and grain. 2.Parameter: Model, hf20-6-ii-ch, hf30-6-ii-ch Power supply, ac 380 v, 50hz, 3 phase four wire Input power, 30kva, 45kva Output power, 20kw, 30kw Frequency, 6.78mhz/ 13.56mhz/27.12mhz Radio tube, fu834 fa, fu924 fa Commutate type, three phase full wave silicon commutate Cooling type, forced air cooled Tuning type, variable capacitance Protection, overload protection, wind pressure protection, door switch protection, filament warm up protection Output type, one/two outputs, one/two outputs Overall size, l1100xw900xh1900mm, l1100xw950xh1950mm Total weight, 700kg, 800kg
