The present application discloses a drying machine and a cell processing apparatus. The drying machine is configured for drying and crystallizing a material. The drying machine includes a vacuum compartment, a crystallization compartment and a heating device. The vacuum compartment forms a first chamber configured to perform vacuum drying on the material. The crystallization compartment forms a second chamber. The first chamber and the second chamber each have an input end and an output end, and the output end of the first chamber is in communication with the input end of the second chamber, such that the first chamber is in communication with the second chamber to form a continuous material channel. The heating device is arranged in the crystallization compartment and configured for heating crystallization of the material in the second chamber.

A negative electrode manufacturing device for lithium secondary battery that is capable of simultaneously performing crystal surface orientation and pre-drying of a carbon-based negative electrode active material at an edge end of a negative electrode slurry is provided. The negative electrode manufacturing device provides a drying part using light at an edge of a magnetic part that aligns the crystal surface of the carbon-based negative electrode active material.
