    The production of beer requires strict processes, including the use of some systems, including temperature control systems, which can be used to strictly control A good production temperature is conducive to production.

    Below, Vdobrew will introduce the temperature control system in craft beer equipment in detail.


    1. The temperature control system for craft beer equipment is mainly composed of three parts:

    Thermostat: Compare the received sensor signal with the target temperature (set value), and output the control signal to the operator.

    Sensor: A component that converts temperature into an electrical signal and is installed at the temperature measurement position.

    Operating device: installed on the heating or cooling device, through the electromagnetic switch to control the supply valve to cut off the current.

    Second, the characteristics of the temperature control system composed of three parts

    Thermostat (how it controls)

    When the temperature is lower than the set value, the switch control has output, otherwise there is no output (heating control). In switching control, the normal fluctuation period around the set value is called the oscillation period.

    1. Time delay:

    Switches with high frequency sensitivity are easy to cause vibration and noise, so the switch control needs “time delay” to eliminate the phenomenon of frequent switching. Example: The temperature is controlled at: full scale 400, hysteresis 0.5%, when the set value is 300, the output is turned on at 299 points.

    2. Proportional control:

    It is a control action based on the proportional difference between the measured value and the set value, and the output on or off is proportional to the deviation. The purpose of this function is to keep the temperature closer to the setpoint for a shorter period of time, further reducing overshoot by increasing or decreasing the control period. The output value is set to 50% of the time period.

    3. Differential operation:

    Proportional operation and integral operation are correction operations of control results. Its slowness is complemented by differential operation, which shortens the time required for the control system to reach a steady state.

    4. Integral operation:

    There is a deviation in the proportional control, but after the proportional control and the integral operation are combined, the temperature control is consistent with the set value. The shorter the integral operation, the stronger the integral operation.


    To sum up, the above is an introduction to the temperature control system of craft beer equipment. It can play a good control effect in use, and can ensure a certain stability. The production requirements of the temperature control system and the parameter setting requirements can be timely adjusted. control.
