Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical freeze-drying and dispensing equipment, and more specifically, to a bottle baffle strip for a freeze dryer plate. Background Technology

[0002] Freeze dryers play an irreplaceable role in the pharmaceutical field. Through the principle of low-temperature vacuum sublimation, they effectively remove moisture from drugs (especially heat-labile proteins, vaccines, live bacteria preparations, and antibiotics) while preserving their biological activity and potency to the maximum extent. This allows for long-term stable storage and transportation at room temperature, completely solving the extreme dependence of biological products and high-value-added pharmaceuticals on cold chain logistics. Freeze dryers are core equipment for ensuring the safety of the global pharmaceutical supply chain and improving patients' access to medication.

[0003] Bottle baffles on the inlet and outlet plates of a freeze dryer are crucial. During the feeding stage, they ensure that bottles enter the freeze-drying chamber in an orderly and stable manner, preventing damage or positional deviations caused by disorderly movement or collisions, thus ensuring a smooth and efficient feeding process. During the discharge stage, they effectively prevent bottles from tipping over or scattering due to inertia or external factors when leaving the freeze-drying chamber, ensuring complete and orderly discharge. This, in turn, maintains the stability and continuity of the entire freeze-drying process, reduces product loss and production failure rates, and is of great significance for improving the quality and efficiency of freeze-drying production.

[0004] Existing freeze dryers use bottle-blocking strips on the inlet and outlet trays, such as Figure 1 As shown, the bottle baffle for the feed and discharge plates of the freeze dryer includes a solid strip-shaped body 1, and the upper surface of the front end 2 of the solid strip-shaped body 1 extends forward with an inclined surface.

[0005] The existing bottle-blocking strips used in the inlet and outlet trays of freeze dryers have the following shortcomings: During the bottle feeding and unloading process in the production process, the bottles come into contact with the bottle surface 3 of the bottle baffle strip, and the friction leads to a large number of broken bottles, affecting the product qualification rate. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a bottle-blocking strip for freeze dryer plates, which aims to improve at least one of the problems mentioned in the background art.

[0007] A bottle baffle for a freeze dryer plate includes a strip-shaped body, wherein the bottle face of the strip-shaped body is recessed at the center of the strip-shaped body to form a groove, and the groove divides the bottle face into an upper bottle portion and a lower bottle portion.

[0008] Optionally, both the upper and lower bottle portions are coated with a coating.

[0009] Optionally, the coating is a Teflon coating.

[0010] Optionally, the coating thickness is 2µm to 50µm.

[0011] Optionally, the depth of the groove is 1 / 20 to 1 / 2 of the width of the strip body, and the distance between the bottom of the upper bottle and the top of the lower bottle is 1 / 5 to 4 / 2 of the height of the strip body.

[0012] Optionally, the upper surface of the front end of the strip-shaped body is a forward-extending slope.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By designing grooves, this invention ensures that during the bottle feeding and discharging process, the bottle can only contact the upper and lower parts of the bottle, reducing the contact area, decreasing the breakage rate, and significantly improving the product qualification rate.
