Description

CROSS-REFERENCE TO RELATED APPLICATION This application is a continuation of international PCT application serial no. PCT/CN2023/101668, filed on Jun. 21, 2023, which claims the priority benefit of China application no. 202210996033.0, filed on Aug. 19, 2022. The entirety of each of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of this specification. BACKGROUND Technical Field The present invention relates to the field of enzyme reactors, and in particular to a rotary filtering type two-in-one stirring kettle. Description of Related Art An immobilized enzyme refers to the enzyme immobilized on a carrier by using an artificial method, which is in a locked state in a certain space, and can continuously react, and the reacted enzyme can be recycled. At present, theoretical and application studies of the immobilized enzyme have achieved a number of important results, and are widely used in the fields of food, medicine, chemical engineering, etc. In a traditional process, after a reaction in an enzyme catalytic reactor is completed, a reaction product and enzyme carrier particles are conveyed to a filter for filtration and separation, and then conveyed back to the reactor to continue a next batch of reactions. A traditional filter is single in filtering manner, a screen plate is prone to blockage, filtering time is long, and a separation effect is poor. Moreover, a transport line between the reactor and the filter is long, resulting in long batch reaction period, low production efficiency, and fast enzyme carrier loss.
