Abstract

The invention belongs to the field of test boxes, and discloses a walk-in sample stability test box, which includes a closed box and auxiliary equipment outside the box. The airtight box is a walk-in box. The airtight box is equipped with a temperature and humidity control system, a humidification jet pipe, a high-power dehumidifier, a low-power dehumidifier, a cooling coil, an electric heating tube, a temperature and humidity sensor and A set of air duct system for uniform distribution of processing air, multiple air supply circulation fans, etc. All these functional components are respectively connected with the temperature and humidity control system, and control the start and stop and variable output in the process. The auxiliary equipment outside the box is respectively equipped with an electrode humidifier and a water chiller; through the PID regulator in the temperature and humidity control system, the temperature and humidity can be accurately adjusted; the purpose of the present invention is to provide a large volume, temperature and humidity adjustment A walk-in sample stability test chamber with high precision, good temperature and humidity uniformity, and very low energy consumption.

Description

technical field [0001] The invention relates to the field of test boxes, in particular to a walk-in sample stability test box. Background technique [0002] Pharmaceutical companies must observe whether the properties of the drug have changed during the validity period of the drug, that is to say, they must do drug performance stability experiments. The purpose of the stability test is to investigate the time-varying law of the raw material or pharmaceutical preparation under the influence of temperature, humidity, and light, to provide a scientific basis for the production, packaging, storage, and transportation conditions of the drug, and to establish the validity period of the drug through the test. [0003] According to the requirements of the Chinese Pharmacopoeia, every batch of drugs produced by a pharmaceutical company must retain samples within the company and conduct stability experiments on the drugs. With more and more varieties and batches of products, the walk...
