Liquid filling machines are used to fill a variety of liquids, including various types of beverages, pharmaceuticals and so on. Because the liquid is filled, the liquid filling machine container must be kept clean. The filling container used must be strictly inspected and cleaned, so that the beverage after filling cannot be contaminated.

Before the liquid filling machine is used, the temperature of the filling machine tank and the conveying pipeline should be lowered by using water of 0~1 °C. When the filling temperature exceeds 4 °C, the temperature should be lowered first and then the filling operation is carried out. Using the heat preservation tank and constant temperature irrigation, the material can maintain a constant temperature during the specified time of filling, so as to prevent the filling machine from being unstable due to excessive temperature change. In addition, the filling equipment is isolated from other equipment. The lubrication part of the filling machine and the filling material part should be protected from cross-contamination. The lubrication of the conveyor belt should use special soapy water or lubricating oil.

In addition to the cleaning of the filling machine, it is also necessary to keep the filling shop clean and tidy. Because in the production process, the production line cannot be operated normally due to the quality problems of the filling machine. Therefore, when using the filling machine, it is necessary to pay attention to sterilization, ensure clean and low temperature filling.

It is a good method to ensure the bio-stable sterilization of bottled beverages during the production process. It is necessary to control the sterilization time and temperature to ensure the effect, and to avoid excessive sterilization time or excessive temperature, and reduce beverage oxidation. When sterilizing, it should be cooled as soon as possible so that the temperature does not exceed 35 °C. Low-temperature filling is a relatively low requirement for beverage filling. Under normal circumstances, beverages are not easy to be foamed in a low-temperature environment, which is beneficial for filling.

Keep the liquid filling machine clean. All pipes, especially those that are in direct or direct contact with the materials, should be kept clean. Wash them every week. Take water every day and sterilize every time. Make sure the filling machine is clean. The material tank should be brushed and sterilized to ensure that there is no dirt or bacteria in the parts in contact with the material.
