Automatic Rice Packing Machine are used to pack different types of rice, such as indica rice, japonica rice, and glutinous rice. They offer common sizes, including 1kg, 2.5kg, 5kg, 10kg, and 25kg.Automatic Rice Packing Machine Types can be selected based on packaging capacity. Small and medium-sized machines typically produce 800-2000 bags per hour, while large, high-speed machines can reach 2000-5000 bags. The equipment boasts a metering accuracy of ±0.2%-±0.5%. When packing 5kg, standard machines can produce 15-30 bags per minute, while high-speed machines can produce 30-60 bags per minute. The entire process can be automated, and some models feature automatic bag loading, vacuum packaging, date printing, status monitoring, and the ability to package multiple materials.

What are the Automatic Rice Packing Machine Types?

Commonly available automatic rice packing machine types include open-mouth bag machines, pre-made bag machines, vertical machines, and vacuum machines.

Open-mouth bag packaging machines: Suitable for packaging of 5kg and above, especially large-capacity packages such as 25kg and 50kg. They are used for packaging flat-bottomed, open-top woven or sacks and are the most common and traditional type of Automatic Rice Packing Machine Types. Typically, an operator manually puts the bags in place, while the machine automatically performs metering, filling, and unloading. Sealing is then performed by auxiliary equipment or manually.

Preformed bag packaging machines: Primarily used for small-format, high-quality retail packaging, such as 1kg, 2.5kg, 5kg, and 10kg. They are used to package pre-formed, three- or four-side-sealed bags. A robotic arm automatically removes the bag, opens it, metering, filling, vacuuming, sealing, and discharging it.Automatic Rice Packing Machine Types offer a high degree of automation.

Vertical packaging machines: Vertical Automatic Rice Packing Machine Types Suitable for flexible production of small volumes and multiple specifications, typically ranging from 100g to 5kg. Using roll film for on-site bag making, the machine automatically completes the entire bag-making, metering, filling, sealing, and cutting process from a roll of film. The film is rolled into a tube by a former, sealed longitudinally and then transversely at the bottom. After filling, the top is transversely sealed and cut to form a complete bag. Various packaging styles are available, including back-seal, three-side seal, four-side seal, and stand-up pouches.

Vacuum packaging machines: They isolate air, inhibit mold and insect infestation, and extend the shelf life of rice. They also reduce oxidation, reduce volume, save storage and transportation space, and protect against moisture and dust. The material is fed manually or automatically to the packaging film, sealed to form the bag, and vacuumed. Once the vacuum is achieved, the bag is heat-sealed. Finally, the bag is cut and packaged. These machines are suitable for portable bags as small as 250g and 500g, household bags as medium as 1kg, 2.5kg, and 5kg, and commercial bags as large as 10kg and 20kg.

Display of different Automatic Rice Packing Machine Types

What types of bags can be packaged with Automatic Rice Packing Machine Types?

When selecting Automatic Rice Packing Machine Types, some bag types are incompatible with the machine type, so the appropriate bag type should also be considered. Different bags have different packing capacities, so choose the appropriate one based on your specific needs.

Plastic Composite Bags: These are typically made of PET/PE or NY/PE composites. They are puncture-resistant, have a strong seal, and are moisture-resistant, making them suitable for long-term storage. They come in three-side-seal and four-side-seal styles, with common capacities of 1kg, 2.5kg, and 5kg, making them the mainstream choice for small household packaging.

Woven Bags: These are constructed of a woven PP outer layer with a PE inner film, offering excellent load-bearing capacity and low cost. They are typically open-top or seamed-bottom bags with capacities of 25kg and 50kg, and are used for industrial-grade bulk rice transportation.

Vacuum Bags: These are made of a PA/PE composite material, capable of vacuuming to isolate air and extend the shelf life of rice. Three-side-seal vacuum bags are the most common, with capacities ranging from 0.5kg to 10kg, and are suitable for high-end or long-term storage needs.

Paper-Plastic Composite Bags: Made of kraft paper outer layer and PE film inner layer, these bags are environmentally friendly, recyclable, and aesthetically pleasing. Most are square-bottom valve bags with capacities of 10kg and 20kg, balancing practicality and environmental friendliness.

Automatic Rice Packing Machine Types Selection

When selecting an automatic rice packing machine, due to the varying flowability and grain size of different rice types, the choice can be based on the rice's characteristics and production output.

Automatic Rice Packing Machine Types for Rice Types

Indica rice has long, slender grains with good flowability, making it suitable for all four types of packaging machines. Japonica rice has short, round grains with slightly poor flowability, making open-mouth and pre-made bag packaging machines more suitable. Glutinous rice is sticky and prone to bridging and clogging, making open-mouth and pre-made bag packaging machines more suitable. Open-mouth bag packaging machines require a "anti-sticking stirring + vibratory feeding" mechanism, such as a conical feed hopper with a camber-breaking shaft and a vertical spiral feed mechanism, to prevent bridging and clogging of glutinous rice and enable fast and slow feeding of coarse and fine grains.

Automatic Rice Packing Machine Types in terms of Production

Vertical packaging machines are suitable for small to medium production runs, with a single unit capable of 100-500 bags/hour, making them ideal for start-up rice mills or community distribution. Pre-made bag packaging machines are suitable for medium to high production runs, with a single unit capable of 400-800 bags/hour, making them ideal for branded rice products that prioritize aesthetically pleasing packaging. Open-mouth bag packaging machines are designed for large production runs and packaging, with a single unit capable of 300-600 bags/hour. They are suitable for large formats such as ton bags and are ideal for bulk export by grain depots and large rice companies.

As an essential food in daily life, automatic rice packing machines have become an essential choice for the grain processing industry chain. Whether it is a vertical packaging machine, a vacuum packaging machine, an open bag packaging machine, or a pre-made bag packaging machine, Automatic Rice Packing Machine Types not only solve the problems of low efficiency, large errors, and susceptibility to contamination in traditional manual packaging, but also realize the standardization of the entire process from metering, filling to sealing and labeling through automation technology. It meets the needs of households, supermarkets and industries for different functions such as small package retail, large package wholesale, vacuum preservation, etc., and has become an indispensable production link for modern rice processing enterprises.
