Description

Article 30, Paragraph 2 of the Patent Law applies February 19, 2019 Exhibited at HCJ (Kitchen Equipment Exhibition) 2019. Displayed at the International Food Industry Exhibition (FOOMA JAPAN) 2019 on July 9, 2019. Exhibited at Food System Solution 2019 on September 9, 2019.

The present invention relates to steam convection ovens. Specifically, one menu dish can be cooked in a plurality of steps, and after the preceding cooking step, a temperature raising step is provided to raise the temperature up to the set temperature, and after reaching the set temperature, The present invention relates to a steam convection oven capable of easily performing a cooking method for switching to the next cooking step.

Patent Document 1 discloses a step cooking method in which, when heating in a hot water bath in vacuum cooking, the core temperatures of two large and small items are detected, and the temperature of the hot water is changed stepwise for cooking. This step cooking method was also commonly used in steam convection ovens using core temperature and timers.

In a normal step cooking method, after the preceding cooking step, a temperature raising step is provided to raise the temperature up to the set temperature, and after the set temperature is reached, the subsequent cooking step is switched to. However, depending on whether the amount of food material is large or small, the time required to reach the set temperature in the next step is different, as shown in FIG.

Therefore, in the conventional steam convection oven, in order to realize a temperature raising step that raises the temperature to the set temperature after the preceding cooking step, it is necessary to appropriately determine the amount of ingredients in the preceding cooking step, and then Skilled techniques were required, such as appropriately judging and inputting the time required to raise the temperature to the set temperature of the cooking step.

For example, as shown in FIG. 3, in the case of steamed cooking that requires 4 minutes of steamed cooking at 99 degrees Celsius and 5 minutes of grilled cooking at 150 degrees Celsius, the time for the temperature raising step when the amount of ingredients is small is 2. Minutes and 30 seconds are sufficient, but if the amount of ingredients is large, 5 minutes is required.

That is, if the amount of food in the preceding cooking step is small, the time to reach the set temperature will be short, and if the amount of food is large, the time to reach the set temperature will be long. In order to set the temperature for the next cooking step so that it can be cooked for a specified time after reaching the appropriate temperature, an expert predicts the time to reach the set temperature for the next cooking step according to the amount of ingredients. requires skill.

However, in industries such as supermarkets and convenience stores where many part-time workers are used, there is a problem that skilled technicians cannot be secured, and there was a demand for a steam convection oven that even beginners can work like a veteran.
