juice filling machine

In the beverage industry, hot-fill and cold-fill juices are two common packaging methods. Here is a detailed comparison of the differences between the two:     Sterilization Process Hot-fill beverages are heated to high temperatures (85°C-95°C) to eliminate bacteria, yeast, mold, and other microorganisms. The hot product is then filled into sterilized containers. As the product cools, a vacuum forms inside the container, extending the shelf life. In contrast, cold-fill beverages do not require heating. The product and container are sterilized separately before filling, using methods such as filtration, UV, or chemical sterilization. After filling, the product is sealed in a sterile environment to prevent contamination. Shelf Life Hot-fill beverages generally have a longer shelf life, generally 6 to 12 months. Some hot-fill juices can be stored for up to 18 months without refrigeration. However, cold-fill beverages have a shorter shelf life. If not refrigerated, they can usually be stored for 1 to 6 months, and some require refrigeration and have a shelf life of only a few days to a few weeks.     Nutritional value and flavor Hot-filled beverages may lose some heat-sensitive nutrients due to high-temperature processing and cause flavor degradation. Cold-filled beverages retain more natural nutrients and flavors because they are not processed at high temperatures. Its taste and nutritional content are closer to the original juice. Production cost Hot filling requires heating and cooling processes, consumes more energy, and increases production costs. In addition, it also requires heat-resistant packaging materials such as glass jars or aluminum cans, which are relatively expensive. Cold filling uses standard PET plastic or other packaging materials, which reduces material costs. However, it requires an aseptic filling environment and advanced equipment, so the initial investment is higher.     Equipment requirements Hot filling requires equipment that can sterilize at high temperatures and handle heat-resistant packaging materials. Cold filling requires aseptic filling equipment and an aseptic production environment. For small-scale production, a "small juice filling machine" may be more appropriate. For bag packaging, a "bag juice filling machine" or "juice bag filling and sealing machine" can be used for hot filling and cold filling. Product safety Hot filling can effectively kill bacteria and other microorganisms to ensure product safety. However, it may slightly reduce the content of some nutrients. Cold filling ensures product safety by maintaining a sterile environment during the filling process, but requires strict control of the production process to prevent contamination.     Market positioning Hot-filled beverages are usually positioned as affordable, long-shelf-life products suitable for mass consumption. Cold-filled beverages, on the other hand, emphasize freshness and naturalness, and usually target the mid-to-high-end market, attracting consumers who pursue nutritious and delicious beverages. In summary, hot-filled and cold-filled beverages each have their own advantages and disadvantages. Hot filling is ideal for extending shelf life and reducing the use of preservatives, while cold filling can retain nutrition and flavor, but requires stricter production control. When choosing a packaging method, manufacturers should consider factors such as product characteristics, target market, and cost budget to make the most appropriate choice.

Food-grade spout bags are also called twist-off bags or screw-on lid bags. They are suitable for milk, juice, purified water or any liquid with good fluidity. They can also be used to can thick liquids such as honey and ketchup. For chemical products, they can also be used to can shampoo, detergent and other liquids.     Features • Safe material: food-grade PET/PE; for areas with plastic reduction laws, we also provide aluminum foil or aluminum-coated PET versions. • Leak-proof screw cap: You can carry it with you whether you are working or going to school, making it convenient for everyone to travel. After drinking, reseal it and slide the bag into your pocket or backpack - fresh and hygienic every time. • Space-saving self-supporting bottom: It is firmly placed on the shelf and remains flat when empty. • The size varies according to the filling volume of different machines, generally between 100 ml and 500 ml, and can be made to 5 liters if required (the filling volume needs to be determined by the size of the machine filling volume); up to 10 colors of printing can be customized.     Perfect match Our compact spout bag filling machine (pictured above) is tailor-made for this bag. Tabletop design, simple and convenient bagging, 1500 bags per hour - perfect for start-ups, cafes, farmers markets or mobile vending machines. Please contact us for samples, minimum order quantity 100,000 pieces.

Introduction: Side-seal liquid packaging machine is a key equipment in the packaging industry, mainly used to fill liquids such as yogurt, milk and juice into bag packaging. The working principle of this machine is to form the roll film into a bag shape and seal it while filling. Working principle: Film conveying and forming: The roll film is loaded onto the film roll and conveyed to the forming tube through a series of rollers and guides. The forming tube forms the flat film into a cylindrical shape, preparing for the subsequent filling and sealing process. Filling and sealing: As the pre-formed film roller moves forward, the filling nozzle accurately distributes the liquid product into the formed bag. At the same time, the sealing mechanism, which usually consists of upper and lower sealing rods equipped with heating elements, applies heat and pressure to seal the edges of the packaging bag. The sealing process is carried out on both sides of the packaging bag, hence the name "side sealing". Sealing parameters such as temperature, pressure and time can be precisely controlled to ensure a strong and leak-proof seal. Maintenance: Daily cleaning: After each production, thoroughly clean the internal and external surfaces of the machine, especially the filling area, sealing rod and film conveying path. Remove any residual liquid, dirt or packaging material to prevent contamination and potential failures in subsequent operations. Use a clean soft cloth or suitable cleaning agent to ensure that electrical components are not corroded by moisture. Lubrication: The milk packing machine needs to regularly lubricate the moving parts of the machine, such as gears, chains and linear guides, with recommended lubricants. Proper lubrication reduces friction, wear and tear, ensures smooth operation and extends the service life of the machine. Please follow the manufacturer's guidance on lubrication intervals and lubricant types. Seal component inspection: Regularly check the sealing strip for wear, damage or residue accumulation. Clean the sealing surface and replace any worn sealing elements in time to maintain stable sealing quality. In addition, check the heating elements and temperature sensors to ensure precise temperature control. Film feeding system adjustment: Monitor the film feeding tension and guide mechanism to ensure smooth and consistent film feeding. Adjust the tension control device and check the film guide device for any wear or misalignment, which may affect the film forming and packaging quality. Electrical system inspection: Check electrical connections, wiring and control system components for any signs of damage, looseness or malfunction. Ensure that the machine's control panel, sensors and actuators are functioning properly to maintain accurate operation and safety. Conclusion: The yogurt packaging machine plays a vital role in the efficient packaging of liquid products. By understanding its working principles and implementing appropriate maintenance measures, operators can optimize machine performance, ensure stable packaging quality and extend its service life. Regular maintenance can not only avoid potential production downtime, but also ensure the safety and hygiene of packaged products, meeting the needs of the packaging industry and the expectations of consumers.
