[0002] The esterification system in biodiesel production refers to the equipment and system used to carry out esterification reaction between bio-oil or biomass and alcohols (such as methanol or ethanol) under the action of a catalyst, and the reactor is an important part of the system. The existing esterification reactor for biodiesel production cannot effectively mix biodiesel when in use, has low reaction efficiency, and cannot clean the reactor body and stirring rod, which is easy to affect the next reaction effect.

[0003] After searching, a Chinese patent with announcement number CN220393656U discloses an esterification kettle for biodiesel production.
