The invention belongs to the field of 
pharmacy, and particularly relates to an automatic efficient 
heat energy recovery system applied to the 
pharmaceutical industry, which comprises a primary 
recovery tank, a secondary 
recovery tank, a steam recovery tank, a hot water tank, a 
soft water tank, a cooling water tank, a 
cooling tower, a batching kettle, a water bath sterilization cabinet, a multi-effect 
machine, a first distributing head, a boiler and a second distributing head. Sterilization high-temperature water and flash steam are recycled, 
heat energy is recycled to the maximum extent, the 
water supply temperature of the boiler is greatly increased, and 
energy consumption of the boiler is reduced; full-
automatic control is achieved, manual operation errors and tedious labor are avoided, data of all procedures of the hot water recycling 
system are recorded for 24 hours in the whole process, a basis is provided for management, the abnormal alarm function is achieved, risks caused by faults can be prevented, sterilization high-temperature water is recycled, meanwhile, 
power consumption of a 
cooling tower is reduced, repeated waste of 
energy consumption is avoided, and the whole 
system uses 
soft water, and fault maintenance and energy waste caused by scaling of equipment and pipelines are avoided.
