Preferably, if the coagulating liquid containing the cation-containing compound is allowed to flow down a multi-stage coagulating liquid tank and the mixed liquid is dropped therein from the nozzle, the drops will not stick to each other and the residence time can be controlled. Gels with uniform properties can be produced. If the coagulating liquid is allowed to flow at a constant flow rate and the dropped material is moved together with the coagulating liquid, the residence time of the dropped material can be suppressed by adjusting the flow rate of the coagulating liquid. If it is necessary to increase the residence time, simply increasing the length of the coagulation tank or slowing down the flow rate will not make the water flow uniform throughout the coagulation tank, and the drippings will move with the water flow. It is difficult to do so. Therefore, if a multistage coagulation tank is used, the water flow can be made uniform. If a longer residence time is required, the number of stages may be increased.

Further, the separated coagulating liquid may be recovered and reused.

間凍結させ、室温で解凍させる。FIG. 3 is a schematic sectional view of an apparatus for producing an immobilized biocatalyst showing an embodiment of the present invention. The PVA dissolution tank, sodium alginate dissolution tank, and biocatalyst supply tank are equipped with a stirring device and a temperature control device so that raw materials can be prepared. The mixing tank is also equipped with a similar stirring device and temperature control device. The dropping device has a notch near the nozzle hole, and is designed to prevent the mixed layer from sticking around the hole. A schematic representation of the nozzle is shown in FIGS. 4 and 5. The liquid is sent from the dissolution tank and the supply tank to the mixing layer, and from the mixing tank to the dropping nozzle using a pump. If there are contaminants, they can be removed by inserting a filter in the middle of the piping. The mixed liquid discharged from the nozzle is dropped onto the coagulating liquid layer and immediately converted into a spherical acid shape. The coagulating liquid layer is multi-stage, designed to ensure that the flow of the coagulating liquid is uniform throughout the tank, and the residence time in the coagulating liquid can be made constant. The coagulating liquid is an aqueous calcium chloride solution that is pumped from a coagulating liquid storage tank, discharged through a slit in the coagulating tank, and fluidized together with the spherical molded product. The spherical molded product and the coagulated liquid are separated by a mesh belt conveyor. The coagulating liquid is collected by the coagulating liquid recovery tank and returned to the coagulating liquid storage tank for reuse. The spherical molded product is washed with water using a shower. This is frozen at -20°C for 20 hours and thawed at room temperature.
