The invention relates to a low-pressure steam and high-temperature condensate heat energy recycling device, a shaping machine and a drying machine. The low-pressure steam and high-temperature condensate heat energy recycling device comprises a fixed support, a secondary steam generation cylinder, an inlet pipeline, a steam discharge pipeline, a liquid discharge pipeline, a heat exchanging mechanism, a first condensate pipeline, a second condensate pipe and a condensate collecting mechanism. The low-pressure steam and high-temperature condensate heat energy recycling device can collect high-temperature steam condensate produced by a machine which uses steam and produces steam, treats the high-temperature steam condensate in a centralized manner, distributes the produced secondary steam and supplies the steam to the heat exchanging mechanism so as to preheat the new air of the machines such as the shaping machine and the drying machine. By the low-pressure steam and high-temperature condensate heat energy recycling device, steam consumption is reduced, the work efficiency of the shaping machine or the drying machine can be increased greatly, manpower and operation costs can be lowered, product stability can be increased, and a traditional shaping machine or drying machine can be allowed to be energy-saving and environmentally friendly.
