What factors affect the filling effect of filling machine?
Beer is a flavor beverage with unique taste.
It is deeply liked by the general public, especially in the hot summer, when the heat is unbearable, a glass of cold beer can be the most comfortable. In recent years, due to the impact of the price increase of brewing raw materials, the brewing cost of beer has increased. The market competition for beer is becoming more and more fierce.
In order to reduce the cost of beer production and improve the production efficiency of enterprises, we can also start with the production equipment of beer, such as beer filling machine, which can be used as one example, trano beer equipment filling machine manufacturers are mainly engaged in beer brewing equipment, filling equipment and cleaning equipment. Today, I would like to talk about several factors that affect the filling of beer filling machines: 1. The influence of filling pressure on filling effect, we know that beer contains saturated dissolved CO2 gas, which is produced in the fermentation process or added to beer by artificially filling CO, the solubility of beer to CO2 varies with beer temperature and pressure.
For example, when the temperature of beer is 5℃ and the partial pressure of CO2 is 2bar, the saturated solubility of CO in beer is 5g/L.
The solubility of CO2 in beer is proportional to the partial pressure of CO2.
When the pressure of the back pressure gas in the liquid storage tank is lower than the saturation solubility of CO, CO will escape from the beer, resulting in the phenomenon of wine, dissatisfaction with the filling effect of beer.
Therefore, the filling pressure should be higher than the saturated dissolution pressure of CO, and at the same time should be lower than the pressure of the wine to avoid affecting the speed of the wine.
2. The influence of wine delivery pressure on the filling effect. Beer is transported from The sake can to the filling machine through the pipeline.
Most breweries use the back pressure in the sake tank for its transmission power.
Because there is a long pipeline from the sake can to the filling machine. Beer often has unstable pressure when it reaches the filling machine. The fluctuation is relatively large. The liquid level in the liquid storage tank also causes large fluctuations.
This will cause the escape of CO2 in beer and affect the filling effect of beer.
Generally, the wine pressure is required to be 3 bar, and the absolute value of pressure fluctuation should be less than 0. 3bar. We can add a wine delivery pump on the pipeline.
Frequency conversion control technology is adopted to ensure the stability of wine delivery pressure.
The analog electrical signal that changes with the change of pressure detected by the wine cylinder pressure transmitter 4-20mA input PID regulator.
4-output by PID regulator-
20mA continuously control the regulating signal to control the frequency converter, and then the frequency converter controls the rotating speed of the wine delivery pump, thus realizing the purpose of constant pressure wine supply.
Through the above explanation, do you have a certain understanding of the pressure knowledge of beer filling? A high-quality beer filling machine can improve the overall efficiency of production. Beer filling machine is the core equipment of beer packaging production line, at present, the competition in the beer market is becoming more and more fierce.
In order to compete for the market share of beer, beer manufacturers have also made a lot of efforts to save the time and cost of production. In fact, it is not as good as enterprises to strengthen the improvement of production equipment to reduce expenses from raw materials or other ways, because the filling effect of the filling machine directly affects the economic benefits of the enterprise, its adjustment can create greater benefits for the enterprise.
