Alipainetäyttö

Alipainetäyttö, also known as vacuum filling, is a manufacturing process used to fill containers with products under reduced atmospheric pressure. This method is particularly effective for products that are viscous, prone to foaming, or sensitive to air. By creating a vacuum, the air within the container is removed, allowing the product to flow in more easily and completely, minimizing the presence of air bubbles.

The process typically involves placing an empty container into a vacuum chamber. Once the chamber is sealed and the vacuum is established, the product is introduced. The pressure difference between the product reservoir and the inside of the container drives the filling process. As the product enters the container, the displaced air is continuously evacuated. This ensures that the container is filled to its desired level without significant air entrapment.

Alipainetäyttö is widely employed in various industries. In the food and beverage sector, it is used for filling sauces, jams, and carbonated drinks where minimizing headspace and preventing oxidation are crucial. The pharmaceutical industry utilizes this technique for filling vials and syringes with sensitive medications. Cosmetics and personal care products, such as lotions and perfumes, also benefit from vacuum filling to achieve a smooth, consistent fill and extend shelf life. The precision and efficiency of alipainetäyttö contribute to product quality and consumer satisfaction.
