The sterilization mechanism of this sterilization cabinet uses saturated steam as the sterilization medium, and utilizes the physical characteristics of releasing a large amount of latent heat and humidity during steam condensation to keep the sterilized items in a high temperature and moist state. After a set constant temperature time, the main component protein of bacteria solidifies and is killed.
Steam sterilization is the lowest cost, safest, and most effective sterilization method among all sterilization processes. At the same time, it can also sterilize traditional Chinese medicine foam materials, decoction pieces, etc., ensuring the final quality requirements of traditional Chinese medicine products. For the majority of traditional Chinese medicine pharmaceutical companies currently undergoing GMP transformation, this type of equipment can not only reduce their costs, but also control product quality. Therefore, it can be said that the steam composite traditional Chinese medicine powder sterilization cabinet has solved a major problem in the manufacturing process of traditional Chinese medicine and is the preferred equipment for pharmaceutical designers and traditional Chinese medicine pharmaceutical companies.

Main performance characteristics
The cabinet structure adopts a horizontal rectangular structure+reinforced rib jacket+internal drying coil, which is conducive to steam entering the reinforced rib jacket+internal drying coil for preheating first.
Multiple points of steam inlet and exhaust are installed on the inner layer of the cabinet to ensure uniform sterilization temperature inside the cabinet. Strengthen the ribbed jacket and internal drying coil with steam injection and multi-point exhaust to ensure uniform preheating and drying temperature inside the cabinet. Install a water ring vacuum pump in the equipment pipeline. Cabinet vacuum is beneficial for the penetration of steam during sterilization, ensuring sterilization effectiveness, and also facilitating product preheating and vacuum drying.
The equipment is equipped with a dedicated stainless steel sterilization vehicle and sterilization tray, with a reasonable design and large loading capacity, which is conducive to the sterilization and drying effects of the product. The device is controlled by PLC+touch screen+micro panel printer, and users can set various sterilization parameters and print them through the micro panel printer.
Fixed temperature and pressure sensors are installed in the inner chamber, reinforced rib jacket, internal drying coil, and low-temperature steam storage tank. The system analyzes the detection data to ensure dynamic balance of temperature and pressure at all times.

Install movable temperature sensors in the interior to monitor the temperature inside the cabinet in real time, adjust the process automatically according to temperature changes, and meet sterilization requirements.
Adopting airtight sealing technology to ensure the reliability of door sealing.
The equipment is equipped with a dedicated GMP verification interface, which can perform GMP verification of on-site temperature and sterilization effectiveness. The characteristics of sterilization process are as follows:
Preheating: Strengthen the rib jacket and introduce steam into the internal drying coil. The inner vacuum will heat the traditional Chinese medicine powder (minimizing the generation of condensed water when steam enters the inner chamber).
Sterilization: Before sterilization, the inner layer is in a vacuum state and enters from the steam storage tank for sterilization. It is sterilized using instantaneous high-temperature saturated steam (80-105 ° C or 105-121 ° C), and the temperature and time can be set according to user requirements. Flash evaporation cooling and dehumidification: Using the principle of flash evaporation, quickly evacuate and reduce pressure to cool and dehumidify, avoiding prolonged residence time at high temperatures and affecting the composition of the powder;
Drying: Strengthen the tendon jacket and maintain a certain pressure with an internal drying coil, keep warm and heat, vacuum the inner layer, and control the appropriate drying time. The several indicators of the sterilized traditional Chinese medicine powder using a steam composite sterilization cabinet are as follows:
Mold and miscellaneous bacteria index く 10CFU/G
Loose and less prone to clumping of medicinal powder (depending on the variety and situation)
The moisture content of the medicinal powder is ≤ 5% (dry value of the product)
The medicinal powder is not easily discolored
Suitable for 65~134 ° C
