What Grains Suit Automatic Grain Pouch Packing Machine Best

If you're a buyer looking for the perfect match between grains and automatic grain pouch packing machine, let's get straight to the point: it all boils down to three key factors – particle size, flowability, and moisture content. Based on our experience, medium-grain rice, clean wheat, refined oats, and small legumes like mung beans and red beans are undoubtedly the most suitable choices.
We've conducted comparative tests on KaiXiang automatic grain pouch packing machine, and these grains achieve a perfect balance in packaging efficiency and stability. They can help you avoid various annoying problems that plague packaging lines, such as clogging, inaccurate weighing, and poor sealing.

Key Characteristics of Grains Suitable for Automatic Bagging

To be honest, not all grains are suitable for automatic packing equipment. After extensive field testing, we've found the optimal solution: grains with a moisture content of 10-14%, uniform particle size with a size difference of no more than 2 mm, and moderate flowability with an angle of repose of 30-40°.
Ultra-fine grains, such as fine bran, are a nightmare – they generate a lot of dust that accumulates in the feeding chute of KaiXiang machines. On the other hand, grains with extremely irregular shapes, such as unhulled barley, can easily clog the metering system, leading to the shutdown of the entire production line.

The Four Best Grains for KaiXiang Automatic Bagging Machines

Whether you're a small-batch artisanal grain brand or a large processing plant, these four grains work perfectly with KaiXiang's automatic grain pouch packing solutions, consistently delivering reliable results. We've verified this on countless production lines.

• Medium-Grain Rice: Its smooth surface and uniform particle size allow it to pass easily and smoothly through KaiXiang's servo-driven feeding system. For 500g bags, packaging speeds can reach 40-60 bags per minute.
• Polished Oats: Hulled and polished oats have their sharp, rough edges removed, completely avoiding the problem of bag breakage during the sealing process. Incidentally, this is a very common problem with unprocessed oats. KaiXiang's metering cups, customized for the particle size of oats, reduce waste by 8% compared to ordinary packaging machines on the market.
• Clean Wheat: Low impurity content (≤0.5%) is essential. The good news is that KaiXiang's built-in impurity filter works in sync with the wheat flow rate, so you don't have to worry about the feeding chute clogging. A flour mill in Shandong used KaiXiang's machines for wheat packaging, saving the factory a significant amount of labor.
• Small legumes (mung beans, red beans): These small beans have a hard texture and are not easily broken during the feeding process. In addition, KaiXiang's adjustable pressure sealing function ensures that each bag is perfectly sealed, which is crucial for keeping the beans fresh.

KaiXiang's Customization Services

The grains we listed above are ideal choices, but if you're dealing with more niche grain types, don't worry—KaiXiang excels at customized solutions. For high-moisture grains like fresh quinoa, we can add a pre-drying module to the machine. For irregular grains like mixed grains, our flexible metering system automatically adjusts to accommodate differences in particle size. A multi-grain brand in Zhejiang upgraded to KaiXiang's customized packaging solution, increasing production efficiency by 40%. This demonstrates that the right customized solution can bridge the gap between "ideal grains" and the grains used in everyday practice.
