Cell thawing machine and method for operating same

A method for operating a cell thawing machine comprising a heating block comprising a first heating block and a second heating block which form a heating space for accommodating and heating a container in which a predetermined amount of biological material including cells is stored through linear movement by a driving force of a motor, and heat the container accommodated in the heating space through heat provided from a heater;

• and a sensor for changing a position in connection with the linear movement of the heating block and detecting the state of the container disposed in the heating space, the method comprising:
• a first step of preheating the first heating block and the second heating block to a predetermined temperature by driving the heater while one surface of the first heating block and one surface of the second heating block facing each other are in contact with each other;
• a second step of heating the container disposed in the heating space to thaw the biological material while the first heating block and the second heating block are changed to a heating position forming the heating space;
• and
• a third step of changing the first heating block and the second heating block to a standby position by moving the same in a direction of moving away from the heating position such that the container disposed in the heating space can be removed,
• wherein in the second step, the container disposed in the heating space is heated by heat transferred from the first heating block and the second heating block in a non-contact manner without contacting the first heating block and the second heating block.
