When choosing Tetra Pak filling machine, the following principles should be followed:

1. The principle of high productivity and good product quality. Productivity directly reflects the production capacity of the production line. Therefore, the higher the productivity, the better the economic benefits. In order to improve the quality of products, the filling machine with high precision and automation should be selected. But the price of the equipment is also increased, which increases the unit cost of the product. Therefore, in the selection of filling machine, the relevant factors should be considered in combination with the production process requirements.

2. The principle of serving the production process. First of all, the suitable filling machine should be selected according to the properties of filling materials (viscosity, foaming, volatility, gas content, etc.) to meet the production process requirements. For example, for liquor with strong aroma, in order to avoid the loss of volatile aromatic substances, cup filling machine or atmospheric pressure filling machine should be used; for juice liquid, in order to reduce contact with air and ensure product quality, vacuum juice filling machine should be used. Secondly, the production capacity of the filling machine should be matched with the production capacity of the processing and packaging machinery before and after the filling process.

3. The principle of wide process range. The process scope of filling machine machinery refers to its ability to adapt to different production requirements. The wider the process range is, the better the utilization rate of the equipment can be improved, and the multi-purpose of one machine can be realized, that is, the same equipment can be used to fill a variety of materials and specifications. Therefore, in order to adapt to the production requirements of various varieties and specifications, the filling machine with the widest technological range should be selected.
