Description

Technical Field

[0001] This utility model relates to the field of freeze-drying equipment technology, and in particular to an auxiliary component for transferring materials to be freeze-dried. Background Technology

[0002] Freeze-drying is a routine operation in the production of pharmaceuticals or chemical products. The material to be freeze-dried is typically placed in a freeze-drying tray. For materials requiring aseptic processing, they usually need to be filtered through a sterilizing filter before being placed in the freeze-drying tray. During operation, the material outlet of the sterilizing filter is often directly connected to the material inlet of the freeze-drying tray. Because the material outlet of the sterilizing filter is much smaller than the material inlet of the freeze-drying tray, this creates an open operation, potentially leading to contamination of the material to be freeze-dried. Furthermore, the material to be freeze-dried may drip onto the outer wall of the freeze-drying tray, especially when the sterilizing filter is removed. Residual material from the filter outlet is more likely to drip onto the outer wall of the freeze-drying tray, resulting in product powder remaining on the outer wall of the tray after freeze-drying. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an auxiliary component for transferring materials to be freeze-dried, which can realize the closed feeding of freeze-drying trays, avoid open operation, and prevent material leakage.

[0004] To solve the above-mentioned technical problems, the present invention provides an auxiliary component for transferring materials to be freeze-dried, comprising:

[0005] An end cap, which matches the material inlet of the freeze-drying tray, is used to cover the material inlet of the freeze-drying tray when the freeze-dried material is transferred. The top of the end cap protrudes to form a liquid inlet, and the outer diameter of the liquid inlet is equal to the outer diameter of the material outlet of the sterilization filter.

[0006] A flexible tube, one end of which is installed at the material outlet of the sterilization filter, and the other end of which is installed at the liquid inlet;

[0007] A pipe clamp, which is installed on the hose, is used to control the flow of the material to be freeze-dried.

[0008] Preferably, the sidewall of the end cap is formed as a double-layer structure of an outer sidewall and an inner sidewall, with a gap between the outer sidewall and the inner sidewall.

[0009] Preferably, the inner wall of the outer side wall is sealed and securely connected to the material inlet of the freeze-drying tray.

[0010] Preferably, the outer diameter of the inner sidewall is smaller than the inner diameter of the material inlet of the freeze-drying tray.

[0011] Preferably, the hose is fixedly installed on the outer surface of the liquid inlet by a sleeve.

[0012] Preferably, the outer surface of the inlet is circumferentially formed with protrusions to increase the sealing and friction with the hose.

[0013] Preferably, a fixing strap is provided at the connection position between the hose and the material outlet and the liquid inlet of the sterilization filter.

[0014] Preferably, the hose is made of silicone.

[0015] This utility model provides an auxiliary component for transferring materials to be freeze-dried, which connects a sterilization filter and a freeze-drying tray to achieve closed-loop conveying of the materials to be freeze-dried. This avoids open operation and effectively prevents material leakage. The structure is simple, easy to disassemble, and highly applicable, making it suitable for widespread use in the transfer of materials to be freeze-dried. Attached Figure Description

[0020] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] refer to Figure 1 This invention illustrates an auxiliary component for transferring materials to be freeze-dried, comprising:

[0022] An end cap, which matches the material inlet of the freeze-drying tray, is used to cover the material inlet of the freeze-drying tray when the freeze-dried material is transferred. The top of the end cap protrudes to form a liquid inlet, and the outer diameter of the liquid inlet is equal to the outer diameter of the material outlet of the sterilization filter.

[0023] A flexible tube, one end of which is installed at the material outlet of the sterilization filter, and the other end of which is installed at the liquid inlet;

[0024] A pipe clamp, which is installed on the hose, is used to control the flow of the material to be freeze-dried.

[0025] In this embodiment of the invention, the two ends of the hose are respectively fitted onto the material outlet of the sterilization filter and the liquid inlet of the end cap, effectively ensuring the airtightness of the material to be freeze-dried discharged from the sterilization filter during the transfer process before entering the freeze-drying tray. The end cap matches the material inlet of the freeze-drying tray, meaning that when the end cap is placed over the material inlet of the freeze-drying tray, the airtightness is good, effectively preventing material leakage. Therefore, the material to be freeze-dried, transported from the hose to the end cap and entering the freeze-drying tray through the liquid inlet, will not be leaked, achieving airtight feeding of the freeze-drying tray. After feeding is completed, the hose is locked and the flow is cut off using a pipe clamp to prevent the residual material to be freeze-dried at the material outlet of the sterilization filter from dripping onto the outer wall of the freeze-drying tray. In addition, the auxiliary component for transferring material to be freeze-dried provided in this embodiment of the invention has a simple structure, is easy to disassemble, has high applicability, and is easy to widely apply in the transfer operation of material to be freeze-dried.

[0026] In one specific implementation, reference is made to... Figure 2 The end cap has a double-layered structure consisting of an outer side wall and an inner side wall, with a gap between them. Preferably, the inner wall of the outer side wall is sealed and securely connected to the material inlet of the freeze-drying tray, and the outer diameter of the inner side wall is smaller than the inner diameter of the material inlet of the freeze-drying tray. Understandably, the material to be freeze-dried, conveyed from the hose to the liquid inlet of the end cap, flows along the inner wall of the inner sidewall into the freeze-drying tray. The outer sidewall is securely sealed to the material inlet of the freeze-drying tray using a fastening method that matches the material inlet of the freeze-drying tray. For example, the material inlet of the freeze-drying tray generally has a threaded connection structure on its outer wall. Therefore, by setting the inner wall of the outer sidewall to a matching threaded structure, the outer sidewall is threadedly connected to the outer wall of the material inlet of the freeze-drying tray. Both the tightness and sealing performance can meet the usage requirements, and the material to be freeze-dried does not come into contact with the outer sidewall or the material inlet of the freeze-drying tray, reducing the possibility of leakage. After the material to be freeze-dried is transferred, the hose is locked and the flow is cut off using a pipe clamp. The amount of material to be freeze-dried hanging on the inner sidewall of the end cap is very small. When the end cap is removed, it is not easy to drip onto the outer wall of the freeze-drying tray. Therefore, it also effectively prevents material leakage to a certain extent.

[0027] In one specific embodiment, the hose is fixedly installed on the outer surface of the inlet by a sleeve. Preferably, the outer surface of the inlet has circumferential protrusions to increase the sealing and friction with the hose. More preferably, a fixing strap is provided at the connection point between the hose and the material outlet of the sterilizing filter and the inlet. Understandably, the hose has a certain degree of elasticity, which allows it to be securely fitted onto the outer surface of the inlet (similar to securing it onto the sterilizing filter). The circumferential protrusions and fixing straps on the outer surface of the inlet are all designed to increase the sealing between the two and prevent leakage of the material to be freeze-dried.

[0028] In one specific embodiment, the tubing is made of silicone. Understandably, the tubing is preferably made of bio-friendly materials, such as silicone. However, if this is not desired, all bio-friendly materials commonly used in the biomedical field are suitable for this invention.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
