Reasonable selection of liquid filling machine is an important way to ensure product quality and improve economic benefits. Generally speaking, the filling machine with good quality, high efficiency, simple structure, convenient use and maintenance, small size and light weight should be selected as far as possible in close connection with the actual production. Firstly, the suitable liquid filling machine should be selected according to the properties of filling materials (foaming, volatility, corrosiveness, explosiveness, etc.) to meet the production requirements. Secondly, the production capacity of filling machine should be matched with the production capacity of processing and packaging machinery.

1. Principle of Health Grade: Due to the special hygienic requirements of medicine, cosmetics and beverage industry. The parts of the selected filling machine that directly contact the material in structure should be easy to assemble, disassemble and clean, and no dead angle is allowed. Moreover, reliable sealing measures should be taken to prevent the mixing of impurities and material loss.

2. Principles of high productivity and good product quality: The level of productivity directly reflects the production capacity of the production line. So the higher the productivity, the better the economic benefits. In order to improve product quality, filling machines with high accuracy and automation should be selected. However, the price of the equipment has also increased correspondingly, which increases the unit cost of the product. Therefore, when choosing filling machine, the relevant factors should be considered comprehensively according to the production process requirements.

3. Principles of safe operation and convenient maintenance: The operation and adjustment of liquid filling machine should be convenient and labor-saving, safe and reliable. Moreover, its structure should be easy to assemble and disassemble, parts should be universal and standardized, and liquid filling machines with low price, light weight and high explosion-proof grade should be preferred.

4. The principle of wide technological scope: the technological scope of liquid filling machine refers to its ability to adapt to different production requirements. The wider the process scope is, the higher the utilization rate of the equipment will be, and the multi-purpose of one machine will be realized. That is to say, the same equipment can be used to fill many kinds of materials and specifications. Therefore, in order to meet the production requirements of Zhongheng liquid material with multiple specifications, the filler with the widest technological range should be selected. It can adjust filling quantity and filling precision conveniently. The selection and purchase of liquid filling machine must be cautious, not blindly, must be based on the needs of their own enterprises, to buy their own liquid filling machine. A good Zhongheng liquid filling equipment can not only bring good production returns to the enterprise, but also save a lot of management energy, which can be said to kill two birds with one stone.
