Pharmaceutical drying machine

Abstract

The invention provides a pharmaceutical drying machine comprising a base, two supporting rods arranged on the two sides of the base correspondingly, an outer cylinder installed between the two supporting rods in a rotating mode, an inner cylinder installed in the outer cylinder in a rotating mode, an air heater arranged on one side of the base and a heat recovery device connected with an air inlet of the air heater. Both the outer cylinder and the inner cylinder are open, a first end cover capable of opening and closing an opening of the outer cylinder is arranged at the position of the opening of the outer cylinder, and a second end cover capable of opening and closing an opening of the inner cylinder is arranged at the the position of the opening of the inner cylinder. By means of the heat recovery device, hot air entering the heat recovery device can be used for heating air entering the air heater, and therefore the energy consumption of the machine is greatly reduced; a first motor drives the inner cylinder to rotate, the drying speed of medicinal materials can be increased; and meanwhile, the medicinal materials are dried more uniformly, the integrity of the medicinal materials cannot be damaged, the drying efficiency of the machine is effectively improved, and the pharmaceutical drying machine is worthy of further application and popularization.

Description

technical field [0001] The invention relates to the technical field of medicinal material processing, in particular to a pharmaceutical dryer. Background technique [0002] In the processing of medicinal materials, drying of medicinal raw materials is a very important process, which affects a series of procedures such as slicing, grinding, and storage of medicinal materials. However, the existing methods of drying medicinal raw materials usually use open air Drying, and this method has certain requirements on the weather conditions, and usually takes a long time, which is not conducive to mass production. [0003] At present, there are some equipments for drying medicinal materials on the market, but these devices still take a long time to dry medicinal materials, and have high energy consumption, and when drying a large number of medicinal materials, often medicinal materials The drying is uneven.

[0002] In the processing of medicinal materials, drying of medicinal raw materials is a very important process, which affects a series of procedures such as slicing, grinding, and storage of medicinal materials. However, the existing methods of drying medicinal raw materials usually use open air drying, and this method has certain requirements on the weather conditions, and usually takes a long time, which is not conducive to mass production

[0003] At present, there are some equipments for drying medicinal materials on the market, but these devices still take a long time to dry medicinal materials, and have high energy consumption, and when drying a large number of medicinal materials, often medicinal materials The drying is uneven. In the same batch, some are already very dry and some have not met the drying requirements, which seriously affects the work efficiency of pharmaceuticals. The existing equipment for drying medicinal materials has a stirring rod in the drying chamber It is used to stir the medicinal materials in the drying chamber to speed up their drying speed, but this method is easy to destroy the integrity of the medicinal materials, resulting in the inability to maintain the medicinal properties of the medicinal materials for a long time, resulting in a certain amount of waste
