The eggbeater is a commonly used mixing and blending device in food processing, used to beat thick pastes, such as syrup, pasta, egg liquid, cheese, etc. The eggbeater is divided into manual and electric.
When the egg beater is operating, the mixer rotates at high speed and forced to beat. The materials to be blended are in full contact with each other and rubbed violently, so as to achieve the functions of mixing, emulsifying, inflating the egg beater, and eliminating part of the water. Because the viscosity of the blending material is lower than that of the dough mixer, the speed of the eggbeater is higher than that of the dough mixer, generally in the range of 70 ~ 270r / min, which is called a high-speed blender.
The eggbeater is mostly manual and vertical, consisting of agitator, container, rotating device, container lifting mechanism and machine base. How to measure and control, of course you must know that measurement and control are measurement and control, what to measure, measure the concentration of the solid liquid mixture in the container, that is, viscosity, what to control, and control the speed of the rotating device. The most commonly used measurement of viscosity is an acceleration sensor. I'm not sure what sensor it uses, but if I design it, I will definitely use an acceleration sensor. According to the knowledge of physics, the first law is f = ma, and the second object is in a liquid of different viscosity. The laws of movement are different and there is not a complicated relationship. The sensors on the rotating device collect concentration information to the controller, and through feedback adjustment, usually feedback voltage information to the control device, and the speed of the voltage is adjusted to adjust the speed of the speed. Automatic control is used here Knowledge of negative feedback in principle.
Generally speaking, when the concentration is high, it needs to accelerate the rotation. After the turn, the eggs are beaten almost. The feedback signal goes back to know that the concentration is small, and the eggbeater reduces the speed.
The above is how the egg beater judges whether the egg beater is completed. For more exciting content, please follow us.
