With the development of science and technology, most of the current liquid products use mechanized filling instead of the original manual operation, which improves the productivity, guarantees the product quality, and can reduce the mutual pollution between the production environment and the materials to be loaded. Classification of filling machines: different filling materials (gas-containing liquids, gas-free liquids, pastes, etc.) and different packaging containers (bottles, cans, boxes, buckets, bags, etc.), and the variety of filling machines is not used. To be the same, the classification methods for filling machines are usually the following:
1. According to the structure: linear filling machine, rotary filling machine
2. According to the quantitative device: cup type canned machine, liquid surface filling machine, rotor type filling machine, plunger type filling machine
3. According to the number of filling valve head: single head filling machine, multi-head filling machine
4. According to the filling principle: vacuum filling machine, normal pressure filling and filling machine, back pressure filling machine, negative pressure filling machine, pressure filling machine
5. According to the supply tank structure: single chamber feeding filling machine, double chamber feeding filling machine, multi-room feeding filling machine
6. According to the degree of automation: manual filling machine filling machine, semi-automatic filling machine, automatic filling machine, filling pressure filling machine
7. According to the lifting structure of the packaging container: slide type lifting and filling machine, pneumatic lifting and filling machine, slide pneumatic combination lifting and filling machine
Selection of filling machine: Reasonable selection of filling machine is an important way to ensure product quality and improve economic efficiency. In general, close contact with production practice, try to choose a filling machine with good quality, high efficiency, simple structure, convenient use and maintenance, small size and light weight.
Filling machine knowledge The following principles should be followed when selecting a filling machine:
1. The principle of high productivity and good product quality. The level of productivity directly reflects the production capacity of the production line. Therefore, the higher the productivity, the better the economic benefits it produces. In order to improve the quality of the product, a filling machine with high precision and high degree of automation should be selected. However, the price of the equipment has also increased correspondingly, increasing the unit cost of the product. Therefore, when selecting a filling machine, the relevant factors should be considered comprehensively in combination with the requirements of the production process.
2. The principle of serving the production process. First, the appropriate filling machine should be selected according to the nature of the filling material (viscosity, foaming, volatility, gas content, etc.) to meet the production process requirements. For example, in the case of concentrated aromatic liquors, in order to avoid loss of volatile aromatic substances, a cup-type or atmospheric-pressure filling machine should generally be used; for juice-type liquids, in order to reduce contact with air and ensure product quality, generally, it should be adopted. Vacuum and juice filling machine. Secondly, the production capacity of the filling machine should be matched with the processing capacity of the processing and packaging machinery before and after the process.
3. The principle of wide process range. The scope of the filling machine refers to its ability to adapt to different production requirements. The wider the process range, the more the equipment utilization 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 various specifications. Therefore, in order to adapt to the production requirements of many varieties and specifications of the beverage and beverage industry, the filling machine with the widest process range should be selected.
