Problems solved by technology

However, although the high-speed motor has a high speed and better crushing effect, the motor power and heat are also large, which leads to the following problems in the existing filter-free soymilk machine: 1) The power of the high-speed motor is higher than that of the ordinary motor, and the energy consumption is high, which invisibly improves 2) The high-speed motor generates a lot of heat during beating, and the heat generated by the motor will cause the temperature of the slurry to rise, and there is a risk of overflow when the soymilk machine is beating with the motor
[0006] 4. Soybean milk machine uses thyristor to control heating tube in order to achieve low power heating, but because the rated current of heating tube is large, the greater the current, the greater the heat generation of thyristor, so besides the necessary drive circuit, thyristor needs additional Increase the heat dissipation of the heat sink, and the cost of the whole circuit is higher
This control method SCR is turned on at non-zero crossing points, and it will also generate a lot of EMI interference.
