Description

Technical Field

[0001] The utility model relates to the field of freeze-drying technical equipment, and specifically, to a freeze-drying rack for vials. Background Art

[0002] With the advantages of thorough dehydration, long shelf life, good reconstitution property, and the ability to maximize the protection of the composition structure and properties of samples, the freeze-drying technology has attracted much attention in the fields of medicine, biology, food industry, etc. Laboratory freeze dryers are indispensable tools in the fields of biomedicine, food, and chemical industry. Some institutions predict that the global market size of laboratory freeze dryers will reach 150 million US dollars in 2029, with a compound annual growth rate (CAGR) of 3.3% in the next few years.

[0003] Calibrators or quality control products are composed of main raw materials, biological excipients, chemical excipients, or buffer systems, etc. The main biological raw materials provide the analyte components to be measured for calibrators or quality control products, and biological excipients, chemical excipients, and buffer solutions build an appropriate and stable storage environment for the analyte to enable its long-term stability. The appearance form can be divided into two forms: liquid and freeze-dried powder, and the best form is freeze-dried. Currently, the vial freeze-drying method is mostly adopted, and the vial freeze-drying production line is relatively perfect in the pharmaceutical field. However, it is found through observation that there is no good light-shielding measure during sample dispensing, and the performance of the materials that need to be protected from light in the vial will be reduced. It is difficult to transfer the materials after being filled. Before entering the box, the material tray is pulled to the pallet, and the vials do not have a good fixation and are prone to tipping over during accumulation. For example, the loading rack and freeze-drying cabinet for injection vials provided by patent CN217295387U, although it fixes the vials, fails to solve the problem of light shielding.
