Abstract
Description
Technical Field
[0001] This utility model relates to the field of heparin sodium processing technology, specifically to heparin sodium freeze-drying equipment. Background Technology
[0002] In the processing and production of heparin sodium, a vacuum freeze-drying device is used to freeze the moisture in the heparin sodium, and then directly sublimate it from solid to gas under vacuum to complete the drying. In the existing technology, the heparin sodium freeze-drying device does not receive uniform heat radiation after freezing, resulting in an unsatisfactory drying effect.
[0003] For example, patent publication number CN209940879U describes a drying device for preparing sodium heparin, including a drying chamber, a freezing device, and a vacuum device. The drying chamber is divided into a freezing chamber, a buffer chamber, and a drying chamber. A conveyor belt is installed inside the drying chamber. The freezing chamber is connected to the freezing device via a pipe and has an inlet. The collection tank is connected to a cold energy recovery device. The drying chamber has an outlet and is connected to the vacuum device via a vacuum pipe. A microwave transmitter is installed inside the drying chamber. The drying chamber is divided into a freezing chamber and a drying chamber. The moisture in the material is first condensed into ice crystals, and then heated to directly sublimate into gas, reducing the amount of condensate produced during the drying process. Microwave heating directly heats the material, avoiding heat loss and ensuring a uniform temperature inside the drying chamber, further reducing condensate production. Through freezing in the freezing chamber and microwave heating in the drying chamber, sodium heparin can be fully dried. However, this sodium heparin freeze-drying device has a problem: the degree of heat radiation received by the frozen sodium heparin is uneven, resulting in an unsatisfactory drying effect.
