Firstly, check and improve the uneven heat conduction. Uneven heat conduction is often caused by poor contact or uneven contact area between the pot bottom and the fire source (such as electric heating tubes or flames). You can try adjusting the placement of the mixing pot or adjusting the fire source to ensure even contact between the bottom of the pot and the fire source. In addition, it is possible to choose materials with good thermal conductivity to make the pot bottom and improve heat transfer efficiency.
Secondly, adjust and improve the temperature control system. The instability of the temperature control system may lead to inaccurate temperature control, resulting in uneven temperature. You can check the position and status of the temperature sensor to ensure that it accurately senses temperature changes. Meanwhile, it is possible to consider using higher precision temperature control devices or increasing the number and distribution of temperature sensors to improve control accuracy.
Once again, optimize the working condition of the mixer. The incompatibility of the mixer may lead to uneven distribution of liquid temperature. The speed, angle, and position of the mixer can be adjusted to better evenly transfer heat to the liquid. In addition, increasing the number and layout of mixers can be considered to improve the mixing effect.
Additionally, other auxiliary measures can also be attempted. For example, a heat exchanger can be added to the liquid wash mixing pot to regulate the temperature through external heating and cooling. The uniformity of the liquid can also be improved by increasing the stirring and circulation speed of the liquid. In addition, an insulation layer can be added to the liquid wash mixing pot to reduce heat loss and improve temperature stability.
