Product Details
1. Overview
1.1 Introduction
The hundred level purification dry heat sterilization cabinet designed and produced by Hubei Hengfeng Medical Pharmaceutical Equipment Co., Ltd. fully complies with the requirements of the 2010 version of China's "Good Manufacturing Practice for Drugs", the 2010 version of the "Pharmacopoeia of the People's Republic of China", and the pharmaceutical machinery industry standards for dry heat sterilization. The product has reached the international advanced level in design, manufacturing technology, and performance. We have rich experience in the design and manufacturing of dry heat sterilization cabinets, and the equipment can fully meet the requirements of the tenderer.
1.2 Model Identification
The JGM series has 5 standard models with a working volume ranging from 1.0 m3_5.0 m3Between them, non-standard products can be designed according to customer requirements.
1.3 Scope of Application
This device is used for sterilization and heat removal of heat-resistant materials in the biological vaccine and pharmaceutical industries. It can also be used for drying heat-resistant materials, such as glass bottles, glass containers, metal products, and equipment components.
1.4 Working principle
Turn on the power switch, start the program, and the oven will automatically run according to the set program. The air inlet fan will be turned on, and fresh air will be continuously replenished to increase the pressure inside the chamber (controlled by a frequency converter). At the same time, the exhaust valve will be opened to discharge wet gas outward. The heated hot air will be filtered by a high-temperature and high-efficiency filter and enter the inner chamber in a laminar flow state, continuously circulating under the action of the circulating fan. Heat up to the set temperature, the interior enters a constant temperature state, the sterilization process begins, and the system automatically counts. After reaching the set sterilization time, the sterilization process ends, and the cooling fan automatically turns on to enter the cooling stage. When the temperature reaches 80 ℃ (which can be set), the system automatically shuts down. Open the door and release items.
