Comparison of filling valve structure and working principle
The mechanical and the electronic filling valve all adopt the isobaric filling principle. The whole filling process flow is similar. We can see from (Fig. 1), the main difference is as follows:
- The electronic filling valve has the function of steam sterilizing wine valve.
- When filling, you need to open the valve to inflate and equal pressure, and then open the liquid valve to return air. The mechanical valve realizes this function by relying on the dial’s mechanical method to lift the valve stem’s fork. In contrast, the electronic valve depends on the electrical control of the cylinder’s piston movement. Which is stable and reliable.
The process of achieving equal pressure filling is different:
Mechanical filling valve:
It realizes the connection of the relevant chambers by controlling the pressing of the guide bar according to the time sequence;
Electronic filling valve:
Connect the corresponding chamber through the switch of the pneumatic diaphragm valve. Smooth movement and guaranteed accuracy. - Different vacuuming methods:
Mechanical filling valve
Add a control valve on the vacuum channel, and add a pressure block on the centring ring. When a bottle lifts the centring ring, its pressing block presses the control valve’s stem. Then open the vacuum valve to vacuum the bottle.
On the contrary, it cannot be vacuumed and cannot reduce the load of the vacuum pump:
Electronic filling valve
The electric eye senses the presence to determine the control of the diaphragm valve switch. And then realize the vacuum function. - Different cleaning convenience:
Mechanical filling valve
The whole valve is placed in the filling cylinder, so it is immersed in the material and not easy to clean. And it will have a stirring effect on the material during operation. Which is not conducive to filling. And the spring may produce microbial contamination of beer. There are dead spots for cleaning, and sanitary conditions are not so good;
The electronic filling valve
It is designed with steam cleaning and centring devices. Make the residual oxygen and harmful bacteria content meet the storage requirements of beer. And overcome the shortcomings of mechanical valve spring immersed in wine. It is easy to clean and prevents the wine from being polluted again. It is an ideal filling valve in the aseptic filling of pure draft beer.

Comparison of filling machine supporting bottle structure and working principle
By a separate feeding screw device, the bottles are supplied to the filling table. All these processes will follow the required state, spacing, and speed. And the bottle holding mechanism will rises. So that the bottle mouth and the filling head are in close contact for filling. After the filling process is completed, it is lowered and reset. The position of the filling valve remains unchanged, only the bottle holder rises and falls. The bottle holding mechanisms have three structural forms:
- mechanical,
- pneumatic,
- and combined mechanical and pneumatic.
The mechanical and pneumatic combined bottle holding mechanism works stably and reliably. The compressed air is circulated in the loop pipe and only needs to supplement the leakage, so it is widely used. It uses compressed air as the power source. Has good shock absorption and buffering capacity. It is not easy to damage the bottle when it fails. But, the movement speed of the piston is effected by the change of air pressure. If the pressure drop is small, not only the rising speed of the bottle will be slowed down. It is also difficult to maintain close contact between the bottle mouth and the filling head. It is easy to cause wine leakage and foaming, and the wine is not full. If the pressure rises greatly, the rising speed of the bottle will increase. It will not be easy to align with the liquid inlet pipe. And make the bottle receive a strong impact force, it is also easy to cause alcohol. The pressure of the bottle holding cylinder has a certain relationship with the filling pressure. Generally, when the filling pressure is 2.0-4.0bar, the pressure of the bottle holding cylinder is 2.5-3.0bar.
From figure 2, we can see that the mechanical valve adopts a mixed centring type lifting mechanism. During the whole process of filling the wine, the bottle, and the wine valve approach or leave as needed. The wine machine keeps the height of the wine valve unchanged. This action is completed by lifting the bottle with the lifting cylinder. When the lifting cylinder revolves around the centre tower, the cam profile changes in the height direction. Forcing the roller to take the lifting cylinder and the outer cylinder to descend. In this way, the bottles after filling the wine also drop together. Disengage the filling valve above.
The electronic valve adopts a mixed eccentric bottle holder and bottle mechanism. Use the pneumatic mechanism to hold the bottle up evenly with self-buffering function. At the same time, it takes advantage of the feature. That the cam descending mechanism can better get smooth motion control. Make the lifting movement of the bottle holder get fast and good working quality.

maintenance and maintenance
Develop detailed monthly and annual maintenance budgets. Strengthen the planned preventive maintenance of equipment. Use equipment classification as the basis. Establish preventive maintenance based on routine inspections and regular maintenance. Establish equipment integrity rate standards and maintenance systems. For those parts with repeated failures, improve and repair the cause of the failure. Prevent the recurrence of similar failures. Identify the key factors affecting the quality of the equipment. Take measures to reduce or eliminate quality defects in the process of development.
