Ceftiofur sodium crystal freeze-drying technology and method

Abstract

The invention relates to the technical field of freeze-drying technologies, in particular to a freeze-drying technology for ceftiofur sodium crystals, and adopts a freeze-drying device which comprises a freeze-drying machine, a door plate is rotatably mounted at the rear end of the freeze-drying machine through a hinge, a placement frame is fixedly mounted in the freeze-drying machine, a plurality of storage devices are placed at the upper end of the placement frame, and the storage devices are arranged in the freeze-drying machine. The storage device comprises a mounting assembly, a scraper assembly, a pushing assembly and a fixing assembly. Through the arrangement of the storage device, a worker can conveniently transport and store a ceftiofur sodium solution into the freeze dryer, the movement amplitude and inertia generated in the transportation process cannot cause overflow of the ceftiofur sodium solution, so that waste is avoided, the worker can conveniently clean the ceftiofur sodium solution, and the working efficiency is improved. And when the freeze-dried ceftiofur sodium crystals are taken out, a special scraper blade is used for stacking and cleaning the ceftiofur sodium crystals, so that the ceftiofur sodium crystals cannot drift away, and the body health of workers can be protected.

Description

technical field [0001] The invention relates to the technical field of lyophilization technology, in particular to a ceftiofur sodium crystal lyophilization technology and method. Background technique [0002] Drying is one of the methods to keep substances from spoilage. There are many drying methods, such as drying, boiling, drying, spray drying and vacuum drying, etc., but these drying methods are carried out at temperatures above 0°C or higher. , The products obtained by drying generally shrink in size and harden in texture. Some substances are oxidized, most of some volatile components will be lost, and some heat-sensitive substances, such as proteins and vitamins, will be denatured. Microbes will lose their biological activity, and the dried substances are not easy to dissolve in water, etc. Therefore, the dried products have great differences in properties compared with those before drying, and the freeze-drying method is different from the above drying methods. The d...

Problems solved by technology

[0003] But present ceftiofur sodium crystal freeze-drying technology and method, when ceftiofur sodium solution is carried out freeze-drying to get ceftiofur sodium crystal, because the device for storing ceftiofur sodium solution is transported into freeze-drying When inside the machine, the ceftiofur sodium solution often overflows due to the amplitude and inertia of the movement, resulting in unnecessary waste, and it is not convenient for the staff to clean up, and the ceftiofur sodium crystals obtained after freeze-drying are in the When taking out, due to the large storage device, ceftiofur sodium crystals will be scattered when taking out, which will also increase the waste of products and endanger the surrounding staff. Therefore, a ceftiofur sodium crystal freeze-drying technology and method
