Imported pharmaceutical continuous consumption system steam liquefaction injector

ImportPharmaceutical continuous consumption system steam liquefaction injectorContinuous sterilization, also known as continuous disinfection, is a process in pharmaceutical continuous disinfection (disinfection) systems where a steam liquefaction injector is used“Rapid heating sterilization, high-intensity micro turbulent mixing, continuous and unobstructed operation”To achieve efficient and energy-saving sterilization of culture media as a core technological feature.

Pharmaceutical continuous disinfection is a method of sterilizing culture media, which includes four stages: preheating, heating, maintenance, and cooling. Preheat the culture medium to60～75℃Afterwards, quickly raise the temperature to126～132℃Maintaining the insulation of the tank5～7After minutes, cool down to40～50℃Finally, it enters the sterilized fermentation tank that has been emptied. The main cooling methods include spray cooling, vacuum cooling, and thin plate heat exchanger cooling.

This technology adopts pipeline operation, and the core equipment includes heat exchangersSteam liquefaction injectorThree types of systems are formed, including heat exchanger combination type, steam direct injection type, and continuous consumption tower-Maintain the combination of tanks. During the sterilization process, the steam pressure needs to be stable at0.044～0.049 MPaAbove, it has the characteristics of high thermal energy utilization rate and short sterilization time, but it needs to be matched with an empty tank sterilization and sterile air pressure holding system. Suitable for large-scale liquid culture medium sterilization, with high requirements for equipment sealing, not suitable for sterilization scenarios containing solid materials.

working principle

Traditional steam injectors have problems such as energy waste and low efficiency, so in practical applications, continuous steam injectors are often used. The continuous elimination steam injector is a special type of steam injector that sprays high-speed and high-pressure steam into an intermediate chamber through a curved nozzle, forming a high-speed rotating steam cyclone. Then, it mixes with low-pressure steam in the cyclone area and increases the energy and pressure of low-pressure steam through the laws of conservation of momentum and energy, thereby achieving steam pressurization and delivery.

technical advantage

Formation of high-intensity micro turbulence: The material liquid and steam are sheared and mixed at high speed at the nozzle, ensuring highly uniform temperature and concentration, and eliminating local overheating or non liquefaction phenomena

Zero insoluble particles: starch dispersed at the bottom, no residual cyclodextrin, creating favorable conditions for subsequent saccharification and filtration

Protein coagulation and separation: Proteins quickly coagulate into clusters and float up after being heated, greatly improving the filtration speed of sugar solution

Non clogging structure: optimized nozzle aperture and flow channel design, even in the presence of whole grains of rice or high concentration starch milk（≥25Be）Under certain conditions, it is not easy to block

Maintenance free disassembly: used by most devices1–3No need to disassemble, wash or clean within the year, ensuring continuous and stable operation of the production line
