II. Packaging Process: Fully Automatic Assembly Line in One Smooth Flow
The fully automatic rice vacuum packaging machine line is not a single machine operation, but a continuous packaging system coordinated by multiple pieces of equipment. With the MCGD8‑200 as the core, it can be equipped with a hoist, multihead weigher and conveyor at the front end, and connected with a checkweigher, case unpacking, cartoning and sealing machine at the rear end, forming a fully automatic line from bulk material feeding to finished product cartoning. The specific processes are as follows:
- Automatic Pouch Feeding: The manipulator sucks empty pouches from the pouch magazine and accurately sends them to the bag clamping station. Bulk rice enters the multihead weigher system through the hoist for automatic weighing.
- Coding: Thermal transfer or inkjet equipment prints production date, batch number and other information on the pouch.
- Zipper Opening: For zipper pouches, the device automatically opens the pouch zipper for subsequent filling.
- Pouch Opening: Suction cups open the pouch mouth and blow air for shaping to ensure full opening.
- Metered Filling: The vertical bag former makes roll film into packaging bags and completes material filling.
- Cleaning: The pouch mouth cleaning device removes residual dust to ensure firm sealing.
- Heat Sealing: The key step is the vacuum shaping system, which vacuumizes the packaging bag and then completes sealing, finally outputting beautiful brick-shaped or hexahedral finished products.
- Shaping: The sealed finished products are smoothed by a shaping plate and conveyed to the conveyor belt.
The whole line runs smoothly without manual intervention, with an operating speed of 1500–4800 bags per hour. The entire process integrates feeding, weighing, bag making, filling, vacuum pumping and sealing, realizing an "unmanned, continuous packaging" assembly line operation mode.
III. Application Scenarios: Covering Diversified Market Demands
The automatic rice weighing packaging machine is not only suitable for packaging grain products such as rice, millet, black rice, brown rice, fragrant rice, glutinous rice, yellow rice, coix seed, oatmeal, buckwheat, sorghum, corn grits, corn kernels, wheat, barley, quinoa, mixed grains and mixed congee ingredients, but also widely used for automated packaging of beans including soybeans, mung beans, red beans, black beans, kidney beans, peas, lentils, broad beans, chickpeas, speckled kidney beans, white beans and green soybeans, nuts and dried fruits such as peanuts, melon seeds, sunflower seeds, pumpkin seeds, black sesame, white sesame, lotus seeds, longans, red dates, raisins, walnuts, almonds, cashews, pistachios, pecans, pine nuts and chestnuts, as well as seasonings, food auxiliary granules and puffed snack granules. The equipment supports multiple pouch types and can flexibly adapt to different product specifications and packaging forms, helping enterprises realize intelligent upgrading of production lines.
IV. Anti-Oxidation Adaptation: Technical Support for Extending Shelf Life
In response to the special requirements of grain products such as rice for anti-oxidation, insect prevention and mold resistance, the fully automatic rice vacuum packaging machine fully considers preservation adaptability in its design. Adopting internal vacuum pumping technology with high-barrier packaging materials, it can strongly remove oxygen and effectively inhibit mold and insect infestation in rice. Using high-barrier packaging materials such as aluminum foil composite bags, vacuum pumping reduces the oxygen concentration inside the package, suppresses the respiration intensity of rice and mold reproduction, prevents rice aging, mold and insects, and better maintains rice quality. Compared with ordinary woven bag packaging, vacuum packaging significantly extends the shelf life of rice and preserves its taste and freshness. Actual tests show that rice and bean products packaged by high-precision vacuum packaging equipment have a shelf life of 12–18 months, while reducing the risk of insect infestation and ensuring stable product quality. It is recommended to ensure the moisture content of rice is below 14% before packaging, and storage away from light can delay fat oxidation.
