The invention discloses an efficient energy-saving
drying machine which is of a
waste heat recycling model, comprising a high temperature heat-preservation cylinder
assembly, a low temperature heat-preservation cylinder
assembly and a multi-source heatpump
assembly. The
machine not only uses the multi-source heatpump technology to improve the
heating efficiency, but also takes the original useless hot air as
heat power supply to absorb heat from hot air by utilizing a heat absorbing coil, meanwhile, the
moisture of the temperature-lowed hot air is condensed into water, the air becomes drier and drier and the temperature becomes higher and higher, after the temperature reaches a seted dgree, a program controller adjusts the working frequency of a compressor by a frequency converter so as to ensure the temperature to keep an optimum temperature. In this way, all
drying machines can save more than 80%
electricity and the invention is certainly one of the most important energy-saving and emission-reduction measures, which is a thorough revolution of the
drying machines. According to that drying all materials in the world needs 3000 billion degrees per year currently, if 80%
electricity can be saved, 2400 billion degrees of
electricity can be saved, 0.864 billion tons of
coal can be saved and 1.4688 billion tons of
carbon dioxide emission can be reduced per year.
