Description

  The present invention relates to a cooking apparatus that cooks food while stirring a food such as jam.

  Conventionally, a cooking apparatus that heats a cooked food while stirring it has been proposed as a means to reduce the burden of cooking by preventing the cooked food such as stew and jam from scorching on the bottom of the pan even if the cook is not completely attached. (For example, refer to Patent Document 1).

  In such a cooking device, in the case of a cooked product such as jam that causes the ingredients to boil to some extent, for example, it is heated to around 80 ° C. and held for a predetermined time to soften the ingredients and soak the taste into the ingredients After performing the preheating process to improve the temperature, cooking is efficiently performed in a short time by executing the stirring process that breaks the outer shape of the ingredients by intermittently rotating the stirring means while maintaining heating at about 110 ° C. There is.

However, in the above cooking apparatus, if the cook tries to operate the cooking apparatus again in order to further boil the ingredients after cooking is completed, a preheating process is performed in which the inside of the cooking container is heated to a predetermined preheating temperature. Since the stirring means does not rotate intermittently until the preheating step is completed, the ingredients cannot be efficiently boiled, which is a problem.

  Next, the operation of the cooking apparatus 10 under the control of the microcomputer 48 will be described with reference to the drawings. FIG. 4 is a flowchart of a cooking program for producing jam.

  In this cooking apparatus 10, as shown in FIG. 1, three kinds of cooking programs and jams for producing breads of different materials by pressing various menu keys 16a, 16b, 16c, and 16d on the operation display panel 16 One cooking program can be selected from the cooking programs for manufacturing the menu, and a menu corresponding to the selected cooking program is displayed on the display unit 16g, and is selected by pressing the start key 16f. Start running the cooking program.

  When a wheat bread menu key 16a is pressed on the operation display panel 16 to select a cooking program for producing wheat bread and a start key 16f is pressed, wheat bread materials such as flour and water charged into the cooking container 20 are selected. A kneading process, a primary fermentation process in which the wheat bread material (bread dough) after the kneading process is left at a predetermined temperature for a predetermined time to perform primary fermentation of bread, and after rotating the stirring means 26 and degassing the bread dough A degassing dough resting process in which bread dough is uniformly inflated by leaving at a predetermined temperature for a predetermined time, a dough rounding process in which the dough is rolled by rotating the stirring means 26, and the dough is left in the cooking container 20 for a predetermined time at a predetermined temperature. The molding and fermentation process for expanding to a predetermined height position, the baking process for baking bread dough, and the atmospheric temperature inside the baking tank 18 are kept at a predetermined temperature. A moisturizing step of decreasing slowly, is continuously performed.

  When the rice flour bread menu key 16b is pressed on the operation display panel 16 to select a cooking program for producing rice flour bread and the start key 16f is pressed, rice flour bread materials such as rice flour and water introduced into the cooking container 20 are selected.

  When a cooking program for producing natural yeast bread is selected by pressing the natural yeast bread menu key 16c on the operation display panel 16 and the start key 16f is pressed, natural food such as flour or water charged into the cooking container 20 is selected. The kneading process of kneading the yeast bread material, the primary fermentation process in which the wheat bread material (bread dough) after the kneading process is left at a predetermined temperature for a predetermined time to perform primary fermentation of bread, and the gas of the bread dough by rotating the stirring means 26 Degassing dough resting process in which bread dough is uniformly inflated by leaving at a predetermined temperature for a predetermined time after drawing, dough rounding process for rotating dough by rotating stirring means 26, and cooking by leaving the dough at a predetermined temperature for a predetermined time A molding fermentation process for expanding the container 20 to a predetermined height position, a baking process for baking bread dough, and an atmospheric temperature inside the baking tank 18 A moisturizing step of decreasing slowly to a constant temperature, is continuously performed.

  Next, as shown in FIG. 4, the jam menu key 16d is pressed on the operation display panel 16 to select a cooking program for producing jam (step S1), and then the time setting button 16e is pressed. The cooking time for jam production is set (step S2). Next, a cooking program for producing jam is executed by pressing the start key 16f, and the process proceeds to step S4 (step S3). Next, in step S4, if the temperature in the cooking container 20 detected by the temperature sensor 30 is equal to or lower than a predetermined value (for example, 60 ° C.), the process proceeds to step S5, and if higher than 60 ° C., the process proceeds to step S6.

  In step S5, the preheating process which maintains the atmospheric temperature inside the baking tank 18 at 85 ° C. for 15 minutes is performed by the heating means 22, and the process proceeds to step S6.

  In step S <b> 6, a stirring process is performed in which the motor 38 is intermittently driven while the atmospheric temperature inside the baking bath 18 is maintained at 110 ° C. by the heating means 22. This stirring process is performed by subtracting the elapsed time from the cooking time set in step S2, that is, when the temperature in the cooking container 20 at the start of the cooking program for producing jam is a predetermined value of 60 ° C. or less, preheating from the cooking time. After subtracting the time for which the process was performed (15 minutes in the present embodiment), when the temperature is higher than the predetermined value of 60 ° C., the cooking program is terminated after the cooking time is executed.

  As described above, in the cooking apparatus 10 of the present embodiment, the temperature in the cooking container 20 is higher than the predetermined temperature, such as when trying to execute the cooking program for manufacturing jam again immediately after the end of the cooking program for manufacturing jam. In this case, it is determined that the preheating step is unnecessary, and the stirring means is intermittently rotated without performing the preheating step. Jam can be efficiently produced according to the customer's convenience.

It is a perspective view of the cooking device concerning one embodiment of the present invention. It is a schematic sectional drawing of the cooking apparatus of FIG. It is a control block diagram of the cooking apparatus of FIG. It is a flowchart of the cooking program which manufactures jam.
