Rapid fixing method of temperature probe

Abstract

The invention discloses a rapid fixing method of a temperature probe, comprising the following steps of: A, location: a fixing module is fixedly arranged in a sterilization container; B, connection: connection using fast connecting chucks is carried out among mobile brackets (1), and the mobile brackets (1) and a fixing bracket (4) of the fixing module are connected by the fast connecting chucks; and C, probe fixing: the probe penetrates into a nozzle of the mobile bracket (1) which is located at the top and out from a hole A (5) of the mobile bracket (1), a mobile sleeve is sheathed outside the probe, and the mobile sleeve and a slot A (6) of the mobile bracket (1) are fixedly connected. The method of the invention has the beneficial effects of having a simple operation process, saving a large amount of time, rapidly and uniformly arranging the temperature probe in any complicated cavity, accurately measuring the temperature of the cavity, improving probe arrangement efficiency, reducing probe replacement cost and overcoming the defects in the prior art that the probe is likely to break and the probe measurement is not accurate.

Description

technical field [0001] The invention relates to the technical field of fixing probes in sterilization equipment, in particular to a fast fixing method for temperature probes. Background technique [0002] Good Manufacturing Practice for Drugs (Revised in 2010) Appendix 1: When thermal sterilization (including moist heat sterilization and dry heat sterilization) is required in Chapter 11 "Sterilization Process" and Chapter 12 "Sterilization Methods" heat sterilization), physical detection means must be used to verify that it has achieved the sterilization effect on all parts of the product or article. Among them, the temperature of thermal sterilization is one of the key physical indicators. [0003] The verification objects include moist heat sterilizers, dry heat sterilizers, tunnel ovens and tanks, etc.; the verification status includes no-load heat distribution, full-load heat distribution and heat penetration test. The strategy used in the actual verification: use limi...

AI Technical Summary

Problems solved by technology

[0005] Probe layout technology for moist heat sterilizers and dry heat sterilizers: when conducting heat distribution tests with no load, place the probes on an empty car for winding. On the one hand, this arrangement will force the probes to be changed. The probe is broken; on the other hand, the temperature probe will be close to the metal bracket of the empty car and the position of the probe will be offset, and the temperature in the cavity cannot be accurately measured

When the heat distribution test is carried out at full load, due to the different device technology, for example, the load has a moving tank, the car cannot be used, and the temperature value in the cavity cannot be measured only by placing the probe on the load.

When conducting the heat penetration test, for the moving tank cavity, three probes are inserted into the tank hole and placed on the upper, middle and lower sides of the vertical line of the cavity. This probe placement method cannot prove that the temperature of all parts inside the cavity reaches Require

[0006] Tunnel oven probe layout technology: when conducting heat distribution test with no load, the probe is fixed on the moving chain with iron wire. On the one hand, this arrangement will force the probe to change, and long-term use will cause the probe to break; on the other hand, the temperature probe There will be deviation in the position close to the tunnel oven track and the probe, and the temperature in the cavity cannot be accurately measured

When testing the heat distribution at full load, the probe is fixed on the bottle mouth with an iron wire and the probe is turned up. On the one hand, this arrangement will force the probe to change, and it will cause the probe to break after long-term use; on the other hand, the temperature probe will appear tight. The temperature in the chamber cannot be accurately measured due to the offset of the position of the glass bottle and the probe

During the heat penetration test, the probe is fixed on the mouth of the bottle or the moving chain with an iron wire and the probe is inserted into the glass bottle at the same time. On the one hand, this arrangement will force the probe to change, and it will cause the probe to break when used for a long time; on the other hand On the one hand, the temperature probe will not rely on the glass bottle wall and the position of the probe will shift, and the temperature of the glass bottle wall cannot be accurately measured.

[0007] Tank probe layout technology: heat distribution test is carried out during online sterilization. Three probes are inserted into the tank hole and placed on the upper, middle and lower sides of the vertical line of the cavity. This probe placement method cannot prove that the temperature of all parts inside the cavity reaches Require

When testing the heat distribution at full load, insert 3 probes into the tank hole and place them at the top, middle and bottom of the vertical line of the cavity, and higher than the stirring paddle. This probe placement method cannot prove that the temperature values ​​of all parts inside the cavity meet the requirements. At the same time, the temperature probe will be wound on the stirring paddle, and the probe will break
