Abstract

When a solid product of a target component is obtained by heating a container in which a solution containing a target component is housed with a heater and evaporating the solvent in the solution, the amount of heating by the heater is controlled based on the detection results of the temperature of the container detected by a temperature detection part so that the temperature of the container approaches a target temperature. At least one of a starting timing T 2 and an ending timing T 4 is then discriminated based on the amount of heating by the heater. Since the amount of heating by the heater varies while being sensitively affected by the vaporization heat generated when the solvent evaporates, the starting timing T 2 or the ending timing T 4 can be accurately discriminated by using the amount of heating by the heater as a discrimination criterion.

First claim

1 . A heating control device for obtaining a solid product of a target component by heating a container in which a solution containing the target component is contained with a heater and evaporating a solvent in the solution, the heating control device comprising:
a controller including
a temperature detection module for detecting a temperature of the container;
a heating amount module for controlling an amount of heating by the heater so that the temperature of the container approaches a target temperature based on the detection results provided by the temperature detection module; and
a timing discrimination module for discriminating at least one of a starting timing at which the solidification of the target component begins and an ending timing at which the solidification of the target component ends based on the amount of heating by the heater.

2 . The heating control device according to claim 1 , wherein the timing discrimination module discriminates at least one of the starting timing and the ending timing based on whether the amount of heating by the heater has reached a prescribed threshold.

3 . The heating control device according to claim 1 , wherein the timing discrimination module discriminates at least one of the starting timing and the ending timing based on an amount of change in the amount of heating by the heater within a prescribed amount of time.

4 . The heating control device according to claim 1 , wherein the timing discrimination module discriminates only a timing outside a prescribed time range as the ending timing.

5 . A heating control method for obtaining a solid product of a target component by heating a container in which a solution containing the target component is contained with a heater and evaporating a solvent in the solution, the heating control method comprising:
controlling the amount of heating by the heater so that the temperature of the container approaches a target temperature based on the detection results provided by a temperature detection module for detecting the temperature of the container; and discriminating at least one of the starting timing at which the solidification of the target component begins and the ending timing at which the solidification of the target component ends based on the amount of heating by the heater.

6 . A non-transitory computer-readable medium including a program for a heating control device for obtaining a solid product of a target component by heating a container in which a solution containing the target component is contained with a heater and evaporating a solvent in the solution, wherein the program makes a computer execute the following steps:
controlling the amount of heating by the heater so that the temperature of the container approaches a target temperature based on the detection results provided by a temperature detection module for detecting the temperature of the container; and discriminating at least one of the starting timing at which the solidification of the target component begins and the ending timing at which the solidification of the target component ends based on the amount of heating by the heater.
