The utility model discloses a dehumidification
system for
drying soft capsules. The device comprises a tray
drying room, a
fresh air bag type primary filter section, a
fresh air and return air mixing section, a first-stage
refrigeration dehumidification section, a second-stage
refrigeration dehumidification section and an air reheating section, the air reheating section is connected with a bag type medium-efficiency filter section through a fan section, the tray
drying room is provided with a laminar flow section, and an air supply section is connected with the bag type medium-efficiency filter section through a high-efficiency filter. The air return section is connected to the
fresh air and return air mixing section and the bag type medium-efficiency filtering section, a fifth temperature and
humidity transmitter is arranged in the air return section, the first-stage freezing dehumidification section is provided with a first
evaporator and a second
evaporator, and the air reheating section is provided with a heat
recovery section and an
electric heating section. A tray space is formed between the air supply section and the air return section. The rotary dehumidification
system has the advantages that constant temperature and
relative humidity of each workshop are ensured so as to meet the requirements of process production, the rotary dehumidification
system is reasonable in structural design, small in influence of external air conditions and long in service life, and the manufacturing cost and
energy consumption are obviously lower than those of a common rotary dehumidification system at present.
