Description

Technical Field

[0001] The present invention relates to the technical field of emulsification equipment, in particular to an emulsification equipment for preparing herpes zoster vaccine. Background Art

[0002] Shingles, an acute infectious skin disease caused by the varicella-zoster virus, causes symptoms such as nerve pain that seriously affect patients' quality of life. Vaccination with the shingles vaccine is an effective means of preventing the disease, and the quality of its preparation process is directly related to the effectiveness and safety of the vaccine. During the preparation of the shingles vaccine, because the vaccine ingredients contain a variety of substances with different properties, such as antigen proteins, adjuvants, and buffers, these substances have different densities and solubilities. Under the influence of gravity and molecular forces, phase separation is prone to occur. Traditional emulsification equipment mostly uses a single stirring or simple shearing method, which makes it difficult to fully mix the vaccine ingredients of different properties and maintain a stable dispersion state. It is difficult to overcome the physical differences between the substances, resulting in frequent stratification problems. Stratification not only affects the distribution of the vaccine's active ingredients and reduces the immune effect, but may also cause safety risks. Summary of the Invention

The motor 3 drives the stirring blade 12 to rotate by rotating the long rod 11 to accelerate the flow of the liquid, and drives the rotor 10 to rotate inside the stator 9 to perform shear emulsification. After the mixing mechanism 6 completes the initial counter-mixing, the motor 3 is The rotating long rod 11 drives the rotor 10 to rotate at high speed inside the stator 9. The mixed liquid entering the shear gap between the stator 9 and the rotor 10 will be subjected to high-intensity shear and collision, and the large droplets will be further broken into micron-sized fine particles, ensuring the uniform distribution of vaccine components, thereby improving the stability of the immune effect. The motor 3 is started, and the motor 3 drives the rotating long rod 11 to rotate. On the one hand, the stirring blade 12 accelerates the flow of liquid in the middle fixed cylinder 5.

The liquid spraying short tube 65 of the upper liquid path component and the liquid outlet nozzle 611 of the lower liquid path component are arranged opposite to each other. When the upper liquid is sprayed from the liquid spraying short tube 65 and the bottom liquid is sprayed from the liquid outlet nozzle 611, the two collide with each other on the side of the stator 9 to form a mixed liquid. Compared with the traditional single stirring, it can achieve full contact between substances of different properties, greatly improve the mixing uniformity, and effectively avoid the stratification problem caused by uneven distribution of components.
