Coffee bean cleaning, peeling, polishing, and selection process principle and flow:

Coffee beans go through a rigorous process before they can be roasted and brewed into coffee.  The process involves several steps that ensure the coffee beans are clean, free of impurities, and have a consistent appearance.

The cleaning process is the first step in coffee bean processing.  It involves removing any foreign materials that may have gotten into the coffee beans during harvesting or transport.  This is done using machines that use air to separate the coffee beans from the debris.

The next step is peeling.  This process involves removing the outer layer of the coffee bean, which is the parchment skin.  This is done using a machine that applies pressure to the beans, cracking the parchment skin and separating it from the bean.

Once the parchment skin has been removed, the beans go through a polishing process.  This involves removing any residual material or rough edges on the beans.  The polishing process is important since it ensures that the beans have a uniform appearance and won't jam during the roasting process.

Finally, after the beans have been cleaned, peeled, and polished, they are sorted based on size, weight, density, and color.  This process ensures that only the best quality beans are selected for roasting and brewing into coffee.

The overall process involves a combination of machines and human expertise to ensure that the coffee beans meet the highest quality standards.  By going through this process, the coffee beans are ready to be roasted and brewed into a delicious cup of coffee.
