At present, beer filling is basically in accordance with the following process Into the bottle → vacuum → carbon dioxide → vacuum → carbon dioxide → filling → standing → pressure relief → bottle. Mechanical valves and electronic valves are identical in process flow. In terms of time allocation, mechanical valves are generally distributed in the form of a rotation angle, because the sliders or levers that control the action of vacuuming, inflating, opening and closing the wine valve (the traditional mechanical valve is only closed) and pressure relief are pressed. The magnitude of the angle of rotation is placed on the control loop, and in practice the magnitude of these angles of rotation is determined by time and is the corresponding angle of rotation shown at normal operating speed. The technical data given by the manufacturer is still time. When the speed is lower than the normal running speed, the time for completion of the entire process increases, and the time is shortened when the speed is overspeed. Therefore, the use of mechanical valve filling beer overspeed operation may affect the filling quality, such as increased oxygen content and liquid level, and even anti-bubble phenomenon. Because in the overspeed operation, the control of all valves is completed by the slider or lever on the control ring, the time between the slider and the lever will be reduced, which will affect the filling quality of the entire filling process. The electronic filling valve control is controlled in time series, and the time for completing each step of the filling process is always the same when the rotation speed changes. If there is no speed limit in the program, the effect of overspeed is only the shortening of the pressure relief time, which affects the subsequent process of zui, and will not have any impact on the previous processes, such as pumping and filling. In summary, when the filling valve is determined, the time for completing each segment of the filling process is determined, unless there is a large margin for each segment when designing or giving technical data, otherwise the quality of the filling is inevitable. Have an adverse effect. Therefore, if you want to improve production efficiency, you should start from improving the efficiency of the whole line and improving the reliability of the operation, instead of increasing the speed of the filling machine.
