Cryogenic treatment equipment with cold energy recovery device

The present invention discloses a processing apparatus with a cryogenic refrigeration recovery unit, including cryogenic equipment housing (1), the liquid nitrogen supply means (2), characterized in that, further comprising: a refrigeration recovery unit (3), a nitrogen outlet and the cryogenic equipment housing (1) is connected to the cold nitrogen exhaust recovering said nitrogen outlet. The present invention at the outlet of a conventional cryogenic processing apparatus nitrogen, arranged for cooling the amount of nitrogen discharged from the cryogenic processing apparatus is recovered and stored by refrigeration recovery, breaking the concept of the traditional cryogenic processing apparatus of the cold direct discharge, this invention is capable of reducing the liquid nitrogen consumption, thereby reducing energy consumption of the apparatus, the present invention also has high recovery efficiency, high operation stability, and so easy to control.
