Case application: Application of Sunwoele VFD (Variable-frequency Drive) on dough mixer
I. Introduction:
The dough mixer is a kind of pasta machine, which is widely used in hotels, bakeries, cake shops, coffee shops, bars, tea houses, families and other occasions. The main thing is to mix the flour and water evenly. There are vacuum mixers and non-vacuum mixers. Divided into horizontal, vertical, single-axis, double-axis, half-axis and so on. The spiral stirring hook is driven by the transmission device to rotate in the mixing cylinder, and at the same time the mixing cylinder is driven by the transmission device to rotate at a constant speed. The flour in the tank is continuously pushed, pulled, kneaded, pressed, fully stirred, and quickly mixed, so that the dry flour is uniformly hydrated, the gluten is expanded, and it becomes a dough with certain elasticity, stretchability and uniform flow.

3. Application site and equipment:
Dough mixer
1. Application site process requirements:
It is required to realize stepless speed regulation, and there are three low, medium and high gears to switch. The third gear can be automatically switched according to the current. When the current exceeds the set value at high speed, it will automatically reduce to low speed immediately; Reduce to low speed to ensure that the equipment is not damaged.
2. Which function of the product is used to solve this application requirement:
Sunwoele VFD (Variable-frequency Drive) adopts high-precision vector control, low-frequency high-torque, fast dynamic response, speed regulation accuracy 0.01HZ, automatic current limiting function, can freely set the required current value, when the motor operating current exceeds the set The frequency will automatically drop to the set value (software built-in parameter) to ensure the normal operation of the machine. The maximum speed of the device is 106HZ, the medium speed is 60HZ, and the low speed is 35HZ. The potentiometer can adjust the speed steplessly. These three speeds will be marked next to the potentiometer. Drive) will automatically jump back to normal speed, which can protect the device from being damaged.

Routine care and maintenance of VFD (Variable-frequency Drive) in this working condition, precautions, etc.:
⑴ Keep ventilation holes in the electrical part of the dough mixer to ensure good heat dissipation of the VFD (Variable-frequency Drive)
⑵ Try not to let water flow into the VFD (Variable-frequency Drive) cabinet during manual operation, so as not to cause short circuit and cause danger
⑶Regular maintenance of VFD (Variable-frequency Drive) in order to prolong the service life of VFD (Variable-frequency Drive)
