In today's increasingly globalized world, food preservation technology has become an important link connecting consumers from various countries. The vacuum packaging machine, this seemingly simple device, actually contains powerful preservation technology, bringing revolutionary changes to the global food industry. Today, we will delve into the working principle, types, and wide applications of vacuum packaging machines in the international market.
The vacuum packaging machine removes the air inside the packaging bag, placing food or other items in a vacuum state, effectively extending their shelf life and preventing oxidation.
The specific workflow includes the following steps:
Putting food in: First, place the food or other items to be packaged into the packaging bag, ensuring that the seal is clean and free of foreign objects.
Sealing preparation: Insert the opening of the packaging bag into the sealing table of the vacuum packaging machine and prepare for sealing.
Sealing and pumping: After starting the machine, the sealing table will heat up and fuse the plastic on both sides together, completing the initial sealing of the packaging bag. Subsequently, the vacuum pump starts working, extracting air from the inside of the packaging bag through pressure difference until a vacuum state is formed.
Secondary sealing: After the pumping is completed, the sealing table will heat up the top of the packaging bag again to ensure a more secure seal at the sealing point.
Complete packaging: After all steps are completed, release the packaging bag and take it out. At this point, the food has been sealed in a vacuum state and can be kept fresh for a long time.
There are many types of vacuum packaging machines, each with its unique application scenarios. Here are some common types:
Food vacuum packaging machine: specially used for vacuum packaging of sausages, meat products, biscuits and other foods, effectively preventing mold and extending shelf life.
Single chamber/double chamber vacuum packaging machine: suitable for food processing plants of different scales, suitable models can be selected according to production needs.
Desktop vacuum packaging machine: compact and portable, suitable for households or small shops, capable of processing various foods such as meat, soy sauce products, seasonings, etc.
Tea vacuum packaging machine: using plastic composite film as packaging material, suitable for vacuum packaging of tea, dried fruits and other products, maintaining their original flavor.
Fully automatic stretch film vacuum packaging machine: uses a forming mold to heat and shape the film, and then vacuum package it, suitable for packaging irregularly shaped products.
Continuous vacuum packaging machine: adopting chain drive, automatic lid swing, continuous output of products, suitable for large-scale production lines.
Vacuum packaging machines have been widely used worldwide, especially in industries such as food, medicine, and chemicals. In the food industry, vacuum packaging machines not only extend the shelf life of food, but also reduce food waste and improve food safety levels. In the field of medicine, vacuum packaging technology is used for packaging drugs and medical devices to ensure their sterility, moisture resistance, and oxidation resistance.
