Abstract
The invention relates to a drink mixing control method which comprises the following steps of: monitoring the flow of the mixed drink through a drink flowmeter in real time, monitoring the flow of a material with low proportion through a material flowmeter in real time, controlling a flow regulation valve locator of the material with low proportion by using a proportional controller, controlling the flow regulation valve of the material with low proportion through the flow regulation valve locator, and regulating the flow of the material with low proportion according to the flow of the drink, so that a proportional coefficient between the flow of the material with low proportion and the flow of the drink is kept to be a constant value. The drink mixing control method is easy to control and obvious in effect, and the precision of the drink mixing proportion can be improved, so that the quality of the drink is improved.
Description
Technical field
The present invention relates to a kind of control method of beverage blends.
Background technology
Usually two kinds of materials are obtained beverage after mix, as syrup and fresh water (FW) are mixed.At present when beverage blends; Usually two kinds of materials are mixed by certain ratio, during mixing, detect the flow of two kinds of materials respectively through flowmeter; Fluctuations in discharge according to every kind of material; Come to control respectively the flow of this kind material through being separately positioned on two kinds of flow control valves on the material feed pipe, thereby control the total flow of beverage, and reach the purpose of control beverage blends ratio.When two kinds of mixing of materials, exist a material proportion bigger usually, another material proportion is less, because there is disturbance unavoidably in material when carrying, the mobile of material can change because of being disturbed.Above-mentioned control method when material that wherein a kind of material, particularly proportioning are bigger is disturbed, can makes the precision of the blending ratio of beverage be a greater impact, thereby influence the quality of beverage.
Summary of the invention
Technical matters to be solved by this invention is: a kind of control method that can improve the beverage blends of beverage blends proportional precision is provided.
For addressing the above problem; The technical scheme that the present invention adopts is: the control method of beverage blends; Step is following: monitor the flow that mixes the back beverage in real time through the beverage flow meter; Monitor the flow of the less material of one of them proportioning in real time through the mass flow meter, the flow regulation valve positioner of the material that usage ratio controller control proportioning is less, the flow control valve of the material that flow regulation valve positioner control proportioning is less; Regulate the flow of the less material of proportioning according to the flow of beverage, make a scale-up factor between the flow of flow and beverage of the less material of this proportioning remain a definite value.
The invention has the beneficial effects as follows: the control method of above-mentioned beverage blends, its control is simple, effect is remarkable, can improve the precision of beverage blends ratio, thereby improves the quality of beverage.
Description of drawings
Fig. 1 is a principle schematic of the present invention;
Among the figure: 1, beverage flow meter, 2, the mass flow meter, 3, proportional controller, 4, the flow regulation valve positioner, 5, flow control valve.
Embodiment
Through specific embodiment the control method of beverage blends of the present invention is done further to describe in detail below.
As shown in Figure 1; The control method of beverage blends; Step is following: the flow that mixes the back beverage through beverage flow meter 1 monitoring in real time; Through the flow of the less material of mass flow 2 real-time one of them proportioning of monitoring, the flow regulation valve positioner 4 of the material that usage ratio controller 3 control proportionings are less, the flow control valve 5 of the material that flow regulation valve positioner 4 control proportionings are less; Regulate the flow of the less material of proportioning according to the flow of beverage, make a scale-up factor between the flow of flow and beverage of the less material of this proportioning remain a definite value.
What above-mentioned control method adopted is the ratio control principle; Promptly two kinds of materials mix by certain ratio; Play a leading role and uncontrollable mass flow is called initiatively amount (like beverage flow); Another kind of mass flow is being called from momentum (like the syrup flow---be the less material of proportioning) of servo-actuated, and it is followed initiatively amount and changes, and numerically both keep certain ratio.
Represent as follows with mathematical formulae:
K＝q2/q1
K is a ratio coefficient in the formula; Q2 is from momentum; Q1 initiatively measures
This controlling schemes is single closed loop ratio control forms, and the measured value that is about to amount (beverage flow q1) initiatively draws the merchant of being divided by as controlled variable through division controller, and setting value is ratio coefficient K.
Characteristics:,, get back on the setting value by initiatively amount (beverage flow q1) decision the certain ratio relation of the maintenance of both flows on original numerical value again through closed-loop path control when changed by disturbance from momentum (syrup flow q2); When changing, also follow variation from momentum when the amount initiatively setting value of momentum (promptly from), both flows keep original ratio relation again under new numerical value.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
