Milling FAQs

The fit of the stone is tight in order for the mill to maintain tight tolerances. One trick to remove it is to rotate the stone while pulling it out. This helps to keep the stone from getting lodged.

No they are hulled  (outer shell removed) and cannot be sprouted.

A high concentration of flour dust suspended in air is explosive, as is any high concentration of powdered combustible material in the presence of oxygen. Although there have been explosions at commercial flour mills, such as the Washburn flour mill explosion near Minneapolis in 1878, flour explosions in home kitchens are very rare. Cooks should not let the fear of fire discourage them from baking or keeping flour at home. Flours stored in airtight containers pose virtually no risk of combustion because they lack the surface area to ignite. Also, the Lee Household Flour mill is designed to contain flour dust.

Our stone mill is not designed to mill moist grains, but if you mistakenly do, there will likely be a stubborn layer of flour left on the inside of the mill. If it doesn’t come off with the regular brush, try a bottle brush, a firm toothbrush, or another coarse brush. When milling sprouted grains, make sure the grains are sufficiently dehydrated prior to milling.

While almost all the grain will feed down and be ground into flour, a small amount of unground may remain in the mill.

The easiest way to put the nylon cover on the bowl is to attach the cover to the mill opening then start at one edge of the bowl and stretch it across until the elastic sits below the lip of the bowl all the way around. Make sure the elastic is snug around both the bowl and the outlet to prevent flour from leaking out and creating a messy situation.

The best way to tell when the mill is done is to listen to the sound of the motor. You'll hear it speed up and see there is no more grain in the hopper.

The time needed to grind flour depends on:

  1. the type of grain being milled
  2. the moisture content of the grain
  3. the grind setting of the mill

Four cups of a soft grain with the mill set to coarse grind could take less than 2 minutes. In general, if you fill the hopper all the way to the 8-cups line with a hard grain and set the control lever to fine, it will take between 20 and 30 minutes. If you only need a few cups of flour to make one loaf of bread, it should take about 10 minutes.

Is Grinding Your Own Flour Healthier? Depends on what you’re paying for in flour. Buying premade organic foods doesn’t give you full control of what you put into your body. Many things labeled as “natural” and “organic” can be more expensive. The price and quality of the ingredients you buy for home grinding will control your costs.

Commercially milled and treated all-purpose flour is chemically treated to minimize cost and prolong shelf life. The reason most people mill their own flour is baking and dietary more than cost.

 

Is Grinding Your Own Flour Healthier? The white and whole grain flour in grocery stores are often treated with chemical agents. During the commercial flour milling process biochemical changes are made to the flour to increase shelf life. The purpose of commercially milled flour is to make money and not be healthy. By grinding your own flour you preserve all the nutritional value. The flour created by you contains no additives of any kind creating healthier bread and baked goods for you and your family.

 

Is Grinding Your Own Flour Low Carb? Depends on what kind of flour you grind. Many bakers elect to grind using other flours besides just wheat. A big part of the reason Quinoa has dramatically risen in popularity in recent years is low carb dieters.

Popular low carb flours:

  • Quinoa Flour
  • Almond Flour
  • Coconut Flour

Stone Flour MillThe Lee Household Flour Mill uses a stationary stone for grinding grain into flour. This traditional milling method removes the need for sifting by fully grinding the grain kernel. Because our mill does not rely on a ‘stone on stone’ design, there is no risk of stone fragments in your flour. The air current from the rotating disk rubs each grain kernel against the stone, reducing it to fine flour.

A picture of the stone and technical details may be found on our website.

Traditional Legacy S-600 Flour Mill from Royal Lee OrganicsThe centrifugal force increased due to the slightly higher RPM motor.  The actual amount of increase will vary based on the type of grain you are milling, smaller grains lower increase, larger grains larger increase.

Lee Flour Mill Replacement Parts and AccessoriesAll interior parts, with exception to the outer housing, are stainless steel, no plastic inside the mill.  The disk, mill blades, adjustable ring, all stainless steel.  The only plastic parts are: Grain hopper, power switch, power cable cord grip, electrical terminal insulation, and a small amount in motor construction…

Can I substitute one kind of flour for another?Generally, yes. Most often, flours are substituted due to wheat allergy or wheat intolerance. While many types of flour can be substituted for wheat flour in equal portions, other types may require slightly more or less. Also, because non-wheat flours lack gluten, it is usually necessary to compensate for this in other ways.

Learn more about different flours in our Flourpedia section.

Do flour mills micronize flour?Yes. Commercial flour millers and high-quality home flour mills reduce grains and seeds to particles the size of a micron. This is called micronization. By definition, it is the pulverization of a substance into particles of just a few microns in size. To give you an idea how small this is, one micron equates to .001 millimeter.

How much faster are electric flour millsTo produce 5 cups of flour (the typical amount needed for a loaf of bread) it takes about half an hour with a hand-operated flour mill. It is not a relaxing process. You will be turning the handle pretty vigorously during this time.

With the Lee Household Flour Mill and other electrically powered home grain mills, it takes about 10 minutes and the only work required of you is to add wheat berries into the hopper as you mill.

Dead Bugs In FlourThere are plenty of small insects that will work their way into bags of flour from your home mill and other pantry items, but the most likely culprits are weevils. These are a species of tiny beetles that get into flour, cereal, rice and other pantry items. They probably hatched from eggs that were already in the flour when you bought it. The reason they were dead is because there is little nutritional value in most store-bought flour.

If you don’t mind eating a few small insects with your baked goods (seriously, it won’t hurt you), you can easily kill off any live insects by storing your flour in the freezer for a few days. Also, scattering some bay leaves around your pantry shelves will help keep pests away.

What are sprouted grains?Sprouted grains are grains (of wheat, rice, barley, etc.) which have begun to sprout. Grains are actually the dormant seeds of cereal grasses. Given the right temperature and moisture, they will sprout. As the popularity of raw food diets increases, many sprouted grain and sprouted legume products are becoming available in stores. You can also sprout your own grains, and use your home mill to prepare them.

Sprouted grains are even more nutritious than whole grain for these reasons:

  • They are easier to digest than unsprouted grains and are lower on the glycemic index, which makes them more agreeable to anyone with blood sugar level concerns
  • They have a higher vitamin content—almost twice the vitamin B6 and folate, and four times the niacin
  • The sprouting process releases the enyzmes, vitamins and minerals within the grain and makes them more easily assimilated
  • They have more protein and less starch than non-sprouted grains

BENEFITS OF MILLING YOUR OWN FLOUR

Cost Savings

Why mill your own flour

A loaf of organic, gluten free bread costs anywhere from 5-7 dollars a loaf or more, and some specialty breads cost as much as 30 dollars a loaf! Baking your own allows you to control the ingredients and spend less. For less than what a loaf of store bought white bread costs, you can make your own organic, whole food bread at home. Your Lee Household Flour Mill can pay for itself in less than a year of use.

Better Flavor and Nutrition

Freshly milled flour yields better tasting, more nutritious breads and other foods. All of the vital nutrients in the wheat berries are preserved, as well as the bran. There is simply no comparison between store-bought enriched white flour and freshly milled whole wheat flour.

Less Spoilage

If you bake a lot, chances are you purchase your ingredients in bulk. Bags of pre-milled flour require dry, cool storage and are prone to staleness. By storing wheat berries in their natural wrapper you will enjoy years of shelf life in the pantry with the option to mill as much, or as little as you need. You control the freshness of your ingredients.

Space Saver

A cup of wheat berries typically yields a cup and ½ of flour.  Our convenient 10lb bags of popular grains fit neatly on the shelf of your pantry. 

How long before freshly milled flour goes rancid?We always recommend milling only as much flour as you need for whatever you are making. However, we understand there is often flour left over in your home mill. Here’s what you need to know:

  • If left in a container in your pantry, freshly milled flour will go bad in about 2 days. There are some who say it should last for 5 days, but we think this is pushing it. Rancidity has been found in freshly milled flour as soon as 2 days after being milled.
  • If stored in the refrigerator in a sealed container, freshly milled flour should be good for 10 days.
  • If stored in a container in the freezer, freshly milled flour will be good for 30 days.

What's better, hand operated flour mill or electric flour mill?This all depends on your situation. If you are preparing for a massive natural disaster, or live in an area with unreliable (or nonexistent) electric service, you will probably want a hand operated mill. 

The drawback to hand operated mills is that it can take quite a while to hand mill as much flour as you need for baking. They also don’t mill as finely as powered mills, and the mill itself is usually a clunky device that has to be permanently mounted to a table or a counter in your kitchen. Fine if you have the room for it. Not so good if you don’t.

On the other hand, electrically powered mills produce extraordinarily fine flour in a very short amount of time. The Lee Flour Mill is also designed to fit on a kitchen counter under most standard kitchen cabinets and can easily be stored out of the way inside a cabinet if desired. In general, you'll find an electrically powered home grain mill far more convenient than a hand powered one.

Can flour be re-milled in Lee Household Flour Mill?Emphatically, NO! Re-milling flour which has already been milled in the machine can damage the motor. While other, less efficient home flour mills may require or even recommend re-milling, this is not the case for the Lee Household Flour Mill. Our mill produces the finest flour of any home flour mill on the market, eliminating the need to re-mill completely. The adjustable settings let you select from coarse to extra fine milling, giving you just the right flour you need without having to mill over and over. 

Can Lee Household Flour Mill be damaged if left running?No. Even if the motor were to overheat, there is an automatic shutoff which will power off the motor if it nears a dangerously high operating temperature. Also, because the Lee mill uses a stationary carborundum milling stone (against which the grain is flung at high velocity by a rapidly rotating impeller), there is no possibility of damaging the stone once all the grain in the hopper has been milled because there is nothing coming into contact with it.

Does the Lee Household Flour Mill have to be cleaned after each use?Yes. Freshly milled flour attracts insects in fairly short order, and the flour trapped inside your mill will become rancid in just a few days if not cleaned out. To keep your mill and your kitchen free of pests, and to ensure the flour you mill is free of any old, rancid flour, you should clean out the grinding chamber and brush off the mill stone after each use.

One of the improvements made on the new Lee Household Flour Mill was to make it easier to clean. The entire cleanup is quite simple and shouldn’t take more than a few minutes.

Can You Mill Flax Seeds?While the Lee mill could certainly mill flax seeds, you would end up with a huge mess inside the mill due to the oily content of flax seeds, and possibly even a clogged grinding chamber. You should avoid milling any oily seeds, grains or nuts. If you only need a small quantity of such seeds or nuts, our suggestion is to purchase a small electric coffee grinder which you use solely for grinding oily seeds and nuts. These are relatively inexpensive and easy to clean after milling something with a high oil content.

How do you know if a grain or seed is safe to mill?If you are unsure about whether a grain might be oily, or have too much moisture to mill, you can try milling a very small quantity (about one-fourth of a cup). If the milled flour clumps together when you pinch it between your fingers, it is too moist/oily to mill. Another test is to put a few grains inside a folded over paper towel and crush them with something heavy. If you can see oil or moisture on the paper towel, don’t try to mill this grain.

You can learn more about milling grains, seeds and nuts in our online Flourpedia.
