Can You Grind Oats In A Coffee Grinder? Yes, you can grind oats in a coffee grinder, as long as the food ingredient is small enough to fit into the feed tube and brittle enough to be broken down by the blades of the coffee grinder, it can be processed in the device.

Most cereals (and I don’t mean what you have for breakfast every morning) and grains fit this description which means they can get ground in your coffee grinder.

However, since they are usually milled in large batches, there are a few things to take note of whenever you want to use your coffee grinder to grind oats into flour.

Things to note before using your coffee grinder to grind oats

Grind in batches

With the growing demand for more gluten-free food on menus, there are innovative ways in which some grains are milled to flour to replace “all-purpose flour” one of such food items is oats, therefore, when you need to grind oats into flour, it is usually done in larger quantities compared to spices and coffee beans.

In order not to overwork your coffee grinder which typically holds about 2-5 cups of food items at a time.

You need to grind the oats in small batches, taking your time with each batch to grind it as smooth as you can get it. That way you get the best results and also maintain your coffee grinder.

Allow coffee grinder downtime

When grinding the oats, ensure you allow the coffee grinder to rest between batches, because when you use it for an extended period it may begin to overheat because of the friction between the blades of the coffee grinder and the dry oats.

Usually, when electronic devices begin to overheat, that’s when they’re most prone to damage, therefore, if you don’t want to factor in a new coffee grinder in your next budget then I suggest you allow it a couple of minutes of downtime to cool down a bit.

Make sure it’s properly dry

You need to ensure the oats are completely free of moisture before you start grinding, if it is not completely dry and you grind it that way, it will affect the texture of the end product which you get, it will also affect the blades of the coffee grinder making them dull overtime— finally, it may cause the coffee grinder to clog because the processed oats may end up being like paste and you’ll have a difficult time getting it out of the coffee grinder.

Always make sure you dry the oats or whatever you want to grind properly before running it through your coffee grinder.

Clean before and after use

You need to clean the coffee grinder before you grind the oats and after you are done, to avoid cross-contamination.

Let me explain, coffee grinders are not just used to grind coffee, they can also be used to grind spices like Peppercorns, cumin, cinnamon, etc.

If you end up grinding oats with the coffee grinder that you just used to grind any of the spices mentioned earlier, you know it will impact the taste of the oats flour when you’re done.

The same goes for not cleaning after you’re done grinding the oats, the coffee beans or spice you grind afterwards will be affected— hence, cross-contamination.
