Technical Description
1. Liquid feed system, utilizing two feed tubes to drip the liquid culture into the granulation tank in droplet form, followed by rapid freezing within a few seconds.
3. Electric stirrer, continuously agitating with liquid nitrogen to prevent particle aggregation and isolation by surrounding gases, ensuring thorough contact between particles and liquid nitrogen.
5. Liquid nitrogen level control, used for adjusting the liquid nitrogen level in the granulator tank.
7. Ventilation system to maintain a slight negative pressure within the refrigeration tank, preventing nitrogen from escaping into the surrounding environment.The feeding and unloading devices are removable and separable.Individual cleaning and...
