Abstract

The invention belongs to the technical field of material drying, and relates to an energy-saving method for sizing and drying soft capsules. The method comprises the following steps of: combining a sizing and drying system device; after evacuating each heat pump cycle in an inner and outer combined type heat pump circulating subsystem, filling heat pump circulating working media respectively; setting the air supply temperature and dew-point temperature in a central control subsystem; starting a major circulating fan and a temperature regulating and humidity regulating circulating fan, and starting each compressor, so that the air supply temperature and dew-point temperature reach set values to realize stable operation; placing the soft capsules to be dried on a multi-layer meshed soft capsule tray of a middle sizing drying chamber in constant thickness, drying for 6 to 8 hours, taking the dried soft capsules out, and drying the soft capsules in the next batch; and circulating in a reciprocating mode to realize continuous production. According to the method, the device system is simple in structure, low in running cost, good in energy-saving effect, large in treatment batch, high in production efficiency, small in floor space and wide in application range.

Description

Technical field: [0001] The invention belongs to the technical field of material drying, and relates to an organic combination of internal and external composite heat pump circulation technology, double-circulation airflow organization technology and complete cross-type convection shaping drying technology, and adopts a drying system device to realize uniform, high-efficiency and energy-saving shaping drying of soft capsules. In particular, an energy-saving soft capsule setting drying method. technical background: [0002] The current general-purpose soft capsule was invented by French pharmacist Mothes in 1883, and the oily medicine is wrapped in capsules to form a dosage form. It has the advantages of being convenient to carry and use, and has been widely used in the pharmaceutical and food fields. There are two methods of pressing and dripping soft capsules. The oily medicine is wrapped in capsules by a pill press or dropping pill machine to form a soft capsule. At this ...
