Description

Technical Field

[0001] This utility model relates to the field of liquid vaccine production technology, and in particular to a trough-type filter. Background Technology

[0002] In veterinary vaccine production, the harvested semi-finished products often contain a large number of impurities, such as numerous fragments in chicken embryo fluid and residual inorganic salts from the production of sheep clostridial disease multivalent dry powder inactivated vaccines. These impurities can seriously affect product quality and cause adverse reactions in animals after injection. Therefore, purification processes are needed to remove impurities and obtain high-quality products. Conventional purification methods include ultrafiltration, centrifugation, and dialysis. Due to the large production volume of veterinary vaccines, purification processes require a large amount of equipment and are complex to operate. In particular, when there are many impurities, equipment blockages frequently occur, requiring frequent replacement of equipment parts during production. This results in low production efficiency, severely affects the lifespan of equipment, and increases production costs. One production team in a certain unit needs to purify 1 million milliliters of semi-finished product per day, taking more than 6 hours, which increases labor intensity and working hours.
