Analysis of Filling Methods of Liquor in China

China's white spirits are filled with various forms. From filling methods, they can be divided into: negative pressure filling, normal pressure filling, quantitative cup filling, siphon filling, plunger filling and flow velocity filling. And so on; from the bottle movement track can be divided into linear filling and rotary filling; from the degree of automation can be divided into automatic filling, semi-automatic filling and manual filling.

1. Negative pressure filling Negative pressure filling can be divided into two-cylinder low vacuum filling, single cylinder low vacuum filling and double cylinder low vacuum quantitative filling. The advantages of negative pressure filling are: the structure of the filling valve is simple, no bottle is not filled, broken bottles are not filled, and wine damage is greatly reduced. How much wine is loaded, the first two are used to determine the height of the wine surface, that is, to control the distance from the wine surface to the mouth of the bottle, and the latter is the capacity type positioning. The main structure of the two-cylinder low vacuum is characterized in that the wine jar is lower than the bottle. The filling principle is: the bottle and the wine valve are sealed, the suction tube is pumped outward from the bottle, and a certain negative pressure is formed in the bottle, the atmosphere will be in the bottle The wine is pressed into the bottle. If the bottle breaks, the bottle will not form a vacuum and therefore will not be filled. The main structure of single-cylinder low vacuum is that the wine jar is higher than the bottle, and the filling principle is: the bottle is sealed with the wine valve, and the suction tube starts to pump air from the bottle. After a certain negative pressure is formed in the bottle, the liquor flows in by its own weight. The bottle, if the bottle breaks, the bottle will not form a vacuum, although the wine valve has been opened, but under the pressure of the atmosphere, the wine will not flow out of the wine valve, so it will not be filled.

2. Atmospheric filling is also called self-flow filling. The main structural feature is that the wine jar is placed above the bottle, and the filling valve is installed at the circumferential position below the wine jar. When filling, the bottle is sealed with the wine valve and then the wine is The top of the valve opens, and the liquid inside the bottle flows into the bottle by its own weight. The air inside the bottle is discharged to the upper part of the bottle through the exhaust pipe. When the liquid level blocks the exhaust pipe, the air inside the bottle is no longer discharged and the filling stops. . The quantitative method of this filling machine is the liquid level positioning, the advantage is no bottle filling.

3, Quantitative cup filling Also known as volumetric filling, from the structure of the quantitative cup can be divided into open cup, semi-closed cup, closed cup. Quantitative cup filling improves filling accuracy compared to constant level filling because it is not affected by bottle shape errors. Its filling principle is: the bottle rises, the bottle mouth first touches the filling valve, so that the valve core moves upwards. During the movement process, the wine inlet is closed first, and then the filling opening is opened. The liquid flows in the bottle by its own weight, and the inside of the bottle The air is discharged into the atmosphere from the mouth of the bottle. After the bottle is filled, it begins to descend and the spool descends. The mouth is closed first, and then the mouth of the wine is opened. After the wine is full, it waits for the next filling process. The filling principle of the opening cup is: the rising of the bottle lifts the measuring cup out of the liquid level of the bottle, and then opens the wine outlet so that the liquid flows into the bottle. After the filling is completed, the bottle is lowered, the wine opening is closed, and the measuring cup is closed. With no wine in it, the liquid fills the measuring cup and waits for the next filling process. The filling accuracy of open and semi-closed measuring cups is generally ±0.5%. The filling accuracy of newly-enclosed Quantitative Cups developed by Xinxiang Light Machine has been further improved. The average error after detection is not more than ±0.15. %, has been much higher than national standards. The advantages of this filling machine are: no bottle filling, high filling accuracy.

4. Piston filling is another form of quantitative cup filling. It is mainly suitable for the filling of larger viscosity liquids, and has higher quantitative accuracy; its filling principle is: plunger at non-filling station Upward movement, the liquid is sucked into the plunger cylinder. In the filling station, the plunger moves downwards to inject the liquid into the bottle. According to this principle, as long as the diameter of the plunger cylinder and the stroke determine the wind-like liquid volume, it is also determined. .

5. Siphonic filling is relatively rare in China. The wine outlet of the wine valve is lower than the liquid level of the wine bottle. The filling amount is the qualitative height of the liquid level of the wine bottle. When the first filling, the liquid needs to be sucked out, and the filling is formal. At the beginning, the bottle opens the valve and the liquid is injected into the bottle by the siphon phenomenon. When the liquid level in the bottle is level with the liquid level of the bottle, the filling is completed, the bottle is lowered and the wine is closed, so that the wine is sealed Wine tube. Will not return to the cylinder, but the filling accuracy of the machine is affected by the liquid level of the bottle. When the seal is not strict, it is easy to drip or return wine.

6, flow speed filling is a simple filling equipment, its filling principle is: liquid flow at a certain speed people take the wine tray, then the wine tray together according to the filling valve uniform and uniform rotation According to the above structure, the quantity of liquid in each valve area of ​​the flow person is equal, and then flows into the bottle. The adjustment of the filling quantity is also very convenient, that is, changing the liquid flow rate or changing the rotation speed of the wine receiving plate. Its biggest advantage is the simple structure, filling a wide range of relative motion, the biggest drawback is that there is no bottle full bottle filling, wine damage higher.

The vast majority of white wine filling machinery is rotary filling because it is easier to achieve smooth, even continuous production. Linear filling is an intermittent production, which is beneficial to the filling of special bottles. Semi-automatic filling machine is mainly used for special-shaped bottles. It is inconvenient to use automatic filling machines. Therefore, manual upper and lower bottles are used for production. In addition, the semi-automatic filling structure is relatively simple, so the price is lower. Automatic filling machine includes automatic bottle filling and start filling. Automatic bottle-out, automatic control of wine tank level, automatic shutdown of failures, thus continuous production. Some automated fillings can automatically adjust the speed according to the number of bottles. Non-failure shutdown automatically starts, thus further reducing the number of workers. The labor intensity, and increase the reliability of normal operation.

All kinds of filling machines above are used for quantification of liquid bottling in two ways: one is the quantification of the liquid surface height, and the liquid level of the quantified method is uniform, which is aesthetically attractive, but how much is the filling liquid Affected by the bottle. The other is the quantitative cup quantification. The wine quantified in this way can be accurately quantified. However, due to bottle problems, the liquid level is inconsistent. This is a considerable contradiction, both in terms of quantitative accuracy and liquid level. Consistent, it is necessary to improve the quality of the bottle, otherwise it is difficult to achieve.

At present, there are thousands of bottles used for white wine filling in China. There are generally phenomena of low quality, such as irregular bottles, off-center bottle mouths, small inner diameter of bottle mouths, large difference in bottle height, and bottle wall thickness. Unequal, etc. These are all threats to the normal use of filling equipment. In order to make the filling equipment still work under these abnormal conditions, it is necessary to choose a filling machine with a flexible bottle holder that can automatically stop when it fails, or a device that avoids this situation by other means to reduce The occurrence of an accident ensures the normal operation of the filling machine.
