Its function is simple, the performance is general, but it can meet the needs of rigid demand, suitable for ordinary household. The fine powder rate of the five-star burr is relatively small, but the ground coffee powder particles are obvious, and there are larger particles.
Six-star bean mill : Compared with five-star bean mill, six-star bean mill has better grinding fineness. The powder will be finer and more uniform. The six-star bean grinder is for those who want to enhance the taste and flavor of their coffee. Its cost performance is relatively high, and its performance and function are better than that of the five-star bean grinder. The graininess of the six-star grinding machine is significantly reduced, but there are still some larger particles.
