The Application of Vacuum Technology in Food Packaging and Freeze-Drying Industries
Over the past two decades, vacuum-sealed packaging has rapidly advanced as a key method for food preservation. This technique effectively removes oxygen, preventing spoilage and extending shelf life. Additionally, vacuum packaging—whether in shrink-wrap or modified-atmosphere forms—safeguards food from insect damage and inhibits mold growth. Its advantages include simple, user-friendly equipment, low operational costs, and affordable plastic materials that are both visually appealing and widely accessible. Common vacuum-packaged products range from pickled vegetables (e.g., mustard tubers, kohlrabi, kelp) to meats (sausages, roast chicken, duck), soy products, milk powder, and malted beverages.The fresh produce supply chain often suffers significant losses due to prolonged intermediary stages between harvest and retail, driving up prices. Vacuum packaging mitigates this by reducing spoilage and refrigeration costs, thus stabilizing prices and easing supply-demand imbalances. As a resul

Working principle of vacuum generator
A vacuum generator is a new, efficient, clean, economical, small vacuum component that uses a positive pressure source to generate negative pressure, which makes it very easy and convenient to obtain negative pressure in places with compressed air or in places where positive and negative pressure are required in a pneumatic system. Vacuum generators are widely used in industrial automation, machinery, electronics, packaging, printing, plastics and robots. The traditional use of vacuum generators is to cooperate with vacuum suction cups to adsorb and transport various materials, especially suitable for adsorbing fragile, soft and thin non-ferrous, non-metallic materials or spherical objects. In such applications, a common feature is that the required air extraction volume is small, the vacuum requirement is low and intermittent operation. The author believes that the analysis and study of the suction mechanism of the vacuum generator and the factors affecting its working performance hav

Application of Vacuum Technology in Aerospace Industry
The main link closely related to vacuum science and aerospace technology comes from the simulation of space environment, because various spacecraft such as launch vehicles, artificial satellites, manned spacecraft, space stations, space probes, and space shuttles are all carried out in the natural vacuum of the universe during space flight.
