Vacuum automatic packaging machines have extremely broad and precise applications in the snack food sector, as detailed below:
Automated Packaging Process:
The vacuum automatic packaging machine can automatically complete a series of operations including bag picking, bag loading, coding, bag opening, material feeding, weighing, filling, vacuuming, sealing, and conveying. For example, the automatic bagging vacuum packaging machine developed by Dongguan Yunzhong Food Engineering Technology Co., Ltd. can perform continuous automated vacuum packaging for snack foods such as chicken feet, duck feet, duck necks, dried tofu, etc., greatly improving production efficiency and effectively solving labor shortage issues for enterprises.
Wide Material Adaptability:
Snack foods come in various shapes and sizes, and the vacuum automatic packaging machine can package liquids, pastes, powders, granules, and solid materials. For instance, equipped with a multi-head weigher, it can quantitatively package granular items like nuts and fried seeds. With a liquid and paste quantitative filling system, it can package fluids like sauces. For soft products like spicy gluten strips, a special pushing device ensures smooth bagging without deformation.
Extended Product Shelf Life:
For plant-based meats rich in unsaturated fatty acids that are prone to oxidation, as well as marinated snacks like eggs and chicken feet, the vacuum automatic bagging machine effectively removes air from the packaging bag, reducing oxygen levels. This inhibits microbial growth and oxidation reactions, extending the shelf life of products like marinated eggs from just a few days under normal packaging to several weeks.
Compatibility with Multiple Bag Types:
Packaging bags for snack foods come in many forms. Vacuum automatic packaging machines typically adapt to various bag types, such as flat bags, stand-up pouches, zipper bags, and shaped bags. Moreover, bags of different widths can be accommodated by adjusting the bag clamp width, which is convenient and time-saving.
Ensured Packaging Quality:
The vacuum automatic packaging machine precisely controls sealing temperature, pressure, and time, ensuring seal integrity and firmness. Even for irregularly shaped products like chicken feet, this prevents air leakage during transportation and storage. Additionally, the equipment is typically made of food-grade stainless steel, eliminating secondary contamination during automated packaging and ensuring food safety.
Customized Features:
Some vacuum automatic packaging machines allow parameter and function customization for specific snack foods. For example, Yilong’s YL-160R fully automatic vacuum packaging machine for cold noodles can intelligently adjust vacuum intensity to prevent the noodles from sticking or breaking. It also supports simultaneous packaging of chili oil packets and seasoning packets, offering consumers a convenient "ready-to-eat" experience.
