Description

Smart milling device {SMART FLOR MILLING APPRATUS}

The present invention relates to a smart milling device, and more particularly, to a smart milling device that has excellent grinding performance by changing grinding conditions depending on the type of grain and in which grains are ground in response to various recipes by grafting IoT. .

In recent years, as the standard of living has improved, consumers' preferences for food have diversified and become more luxurious, and there is a growing tendency to prefer processed foods that are easy to cook and have a high taste preference. In addition, as women's social participation and the increase in the number of single-person households, rice consumption is gradually decreasing, while consumption of substitute meals or convenience foods that replace rice, a staple food, is gradually increasing.

Therefore, in order to satisfy the changing tastes of consumers while promoting rice consumption, various substitutes or convenience foods such as rice cakes, snacks, and bread, which use rice as the main ingredient, are being developed and commercialized.

Furthermore, various grains other than rice are gaining popularity as ingredients for baking and confectionery. In particular, demand for pulverized grain powder as a premix of various foods is increasing.

However, when grains are pulverized by a known mill, the pulverization is performed under the same conditions even though the types of grains are different. In addition, the required particle size and the like are different depending on the final product, and grain powder having the same particle size is produced when grain is pulverized with a known mill.

In this case, grain powders that do not match the characteristics of grains or products are used, resulting in poor taste and texture.

Therefore, it is necessary to develop a milling device that grinds grains so that the final product can have the characteristics of the powder required while having the grinding conditions suitable for the characteristics of various grains.

In the middle classification, uses such as confectionery and baking may be classified. Even for the same grain, for example, grain, the required particle size may be different depending on whether it is for confectionery or baking.

In the small category, various menus such as muffins and croissants may be subdivided even for baking, and recipe information according to each menu is stored.

As described above, the controller 900 controls at least one of the motor of the pin mill 200 and the inverter motor of the blower 500 according to information input from the user terminal 950 . For example, by controlling the inverter motor, the speed of the blower 500 varies according to the suction power of the inverter motor, and when the speed of the blower 500 increases, the suction power increases, and as a result, the particle size of the pulverized grain powder is large and coarse. lose
