เครื่องบรรจุประเภทต่างๆ และการใช้งานที่เป็นเอกลักษณ์

Filling machines are indispensable in various industries where there are requirements for precise filling and packaging of products. They are used to fill products ranging from liquids to powders into containers such as bottles, cans, and pouches. There are different types of filling machines, each designed for specific products and container types. In this article, we will discover various types of filling machines.

 

1. Gravity filling machines: These machines use gravity to fill containers with low to medium viscosity liquids such as water, juice, and wine. The principle of gravity filling is based on the fact that liquids flow downwards due to gravity. The liquid is first poured into a holding tank and then allowed to flow into the container via a gravity-fed nozzle. Gravity filling machines are usually used for filling glass bottles, plastic bottles, and cans.

2. Piston filling machines: These machines use a piston to measure and dispense a precise volume of liquid into containers. The volume is determined by adjusting the stroke length or the size of the cylinder. Piston filling machines are used for filling high viscosity liquids such as oils, syrups, and creams. They are also used for filling products with small particulates such as salad dressings and yogurt.

3. Vacuum filling machines: These machines use vacuum to fill containers with thin to medium viscosity liquids. The principle behind vacuum filling is that the vacuum created in the container draws the liquid into it. A vacuum filling machine has a reservoir that holds the liquid, and a nozzle that is placed inside the container. The machine creates a vacuum in the container, and the liquid is drawn into it. Vacuum filling machines are used for filling glass bottles and plastic bottles.

4. Overflow filling machines: These machines are used for filling containers with thin liquids that foam, such as detergents, shampoos, and soaps. The principle behind overflow filling is that the liquid is filled to a specific level, and any excess liquid overflows into a catchment tray. The machine detects the level of the liquid using sensors and adjusts the filling volume accordingly.

5. Auger filling machines: These machines are used for filling powders, granules, and dry products such as flour, sugar, and spices. The principle behind auger filling is that a screw rotates in a cylinder, moving the product forward and into a funnel that dispenses it into the container. Auger filling machines are precise and can handle a wide range of products.

 

In conclusion, filling machines are an essential part of the packaging process. Different types of filling machines are designed for specific products and container types. The choice of a filling machine depends on the product viscosity, the container material, and the required filling accuracy. Choosing the right filling machine can improve productivity, reduce waste, and enhance the quality of the final product.
