A rocker churn used on the Barthelemy farm near St. Cloud. Children had the task of rocking the churn. It is a Davis Swing Butter Churn #5, manufactured by the Vermont Farm Machine Company, Bellows Falls, Vermont.
A churn is a device for making butter. The following are various types of churns used for making butter at home or on the farm.
The earliest churns were goatskins or other primitive containers in which cream could be agitated. Skin bags were sometimes used by Asian nomads to turn their cream into butter just by shaking the skin bags till the butter was formed.
The regular quart fruit jar has been a churn for many, just a little cream and a lot of agitation was all that was needed.
A more sophisticated version of this concept were rocker type or swing churns and many churns that were powered by animals.
The dash churn , familiar to farm homes for centuries, consisted of a tall, narrow, nearly cylindrical stone or wood tub fitted with a wooden cover. The cream was agitated by a hand-operated vertical wooden plunger, stave, or dash.

Wooden barrel churns
The barrel could be spun freely, and often had a small, built-in window that allowed the churner to keep track of how things were going. "Barrel" churns were used throughout the 1800s.
Metal Dazey churns, 1907.
Another type, widely used in the 19th century, was shaped like a small barrel and mounted in a wooden cradle. Operation of a hand crank caused the barrel to revolve end over end. One of the early manufacturers was Blanchard Churn Company, probably of Nashua, new Hampshire. Around the Civil War times and after, the Union churn company was a major manufacturer, a typical model was a wooden three legged type. Foreign churns were imported into American early colonies and most of these were of some wooden type construction, mostly the tall tapered wooded slatted sided bodies with hand crafted metal bands or some type of early wire bands that held them together. All of these churns had a wooden stomper, that was constructed with a X at the end of a wooden shaft that agitated the cream when moved up and down.
Tin churns were made by numerous manufacturers in the latter 1800's. One of the most common were the metal Dazey churns. These were made in sizes from 1 Gallon to at least 16 gallon types. Most of the larger ones were powered by some external source, other than a hand crank. Some of these older churns had a two handled crank operation, sort of like a bicycle peddle mechanism.
In the later part of the 1800's Stoneware churns were fairly common. Many of these had advantages to offer with the designs and decorations that were part of there outside coating. Galling numbers was common with these churns.
Small churns like this 13" tall, 4 quart Dazey were common in both rural and urban households.

Glass churn jars
Millions of hand-turned glass churn jars were used from the early 1800s through the 1950s or 1960s. Glass butter churns, made in the 1960s, came with electric motors. The evolution of home butter churns continued right up to the point where people started buying butter instead of making it.
Early Glass churns were made in 4 sizes: 1, 2, 3 and 4 quart types. After the mid 1920's the addition of the 6 and 8 quart jar sizes appeared. Horseshoe or Beveled edge jar types were first and then the Bullseye with the square shoulder and the round raised company information on the glass jars. Next came the Slopped shoulder types, the metal tops had a very strait up and down metal grip on the metal crank mechanism, often had a little flower (Daisy) raised on the metal crank side. The slope shoulder churns were supposed to be easier for cleaning and the butter particles did not stick as easily in the upper corners of the jar. After 1936, most of the wooden paddles only had two blades, for it was found that it took the same time for a 4 bladed paddle to churn butter as a two bladed paddle.
The Dazey Company is a well-known manufacturer of glass churn jars. At the beginning of the 20th century, Nathan P. Dazey was producing can openers in Dallas. He met E.B. Jones, a sickly man who had designed a small glass butter churn with a crude dasher. In time, Dazey fully bought out Jones' EZ Churn Company, and became a major manufacturer in the U.S. In 1910, his son Jack came into the business and the company began to grow. The company added other size churns as well as electric churns up to ten gallons. Seeing a market for this design in the rural family homes, he soon was trying to find a foundry to make parts for him. Dallas area was not equipped to handle this assignment, we think now, and he soon found St. Louis more able to meet his needs.
During World War I, there was a shortage of butter and Dazey developed a churn where you could add one pound of butter and one pound of milk and end up with two pounds of butter. The company did very well during the war. In the late 1920's Dazey introduced a wall type can opener with a cutting wheel that revolutionized the can opener industry. At this time the churn business was beginning to decline due to many farmers moving to the cities and Dazey began producing other kitchen items. By the end of World War II, Dazey began manufacture other products, and by the 1950's the brand was sold to Landers, Frary and Clark, the manufacturers of Universal products, and eventually to the Rival Company who eventually killed the brand.
Whey strainers on Dazey churns were not at first used. Probably around 1920 there was introduced a oval type whey strainer with a removable top. This was soon followed by a rather squarish designed slip in unit that did it job fairly well. After 1928 the old Square shoulder jars disappeared from the scene and the slopped shoulder jar came in being. The Patented date would indicate that in 1922, Feb. 14th, the new jars came into being.
One of the more unusual models, used in the 1920s, was a metal and tin framed butter churn with wooden dashers and gears.
Other major manufacturers included the Standard Churn Company of Wapokoneta OH, and Taylor in the St. Louis area produced discounted models. Dazey and the Blow Churn company in England collaborated on several models. Blow churns were made in most of the same sizes that our American churns were made in. (An English Quart has a different oz. size than our American quarts.)
Electricity did not really hit the Midwest until around the early 1940's. Hand made churn butter was a daily staple, often a family member had the chore of making butter once a week. In the later part of the 1930's a new churn was introduced by Dazey Churn Co. that had a round pair shaped jar with somewhat scalloped sides. On the bottom of the Jar held all of the company information. These units were also famous for its red football designed cover of the metal gears that powered the paddles below. These are reported to have came in 2,4,6,and 8 sizes. These churns were just before the electric models came into being and were not manufactured long. Some of the later types of these had a built in whey strainer on the metal cap part
Thousands of companies in some way lead to the making of Butter Churns after the 1700's and up into nearly the mid 1900's. Several dozen churn designs were patented a year. Some of the earliest patents were in the mid 1860's and continued into the 1940's, probably over 2000 churn patent entries.
With the advent of the cream separator in the late 19th century, the manufacture of butter moved from the farm to the factory.
Modern industrial churns are large, barrel-shaped, revolving containers in which the cream is agitated until the microscopic fat globules clump together. The liquid buttermilk is drained, and the butter is washed with sterilized water. Continuous churns, developed in Europe in the 1930s, can produce a ton of butter per hour.
Churning physically agitates the cream until it ruptures the fragile membranes surrounding the milk fat. Once broken, the fat droplets can join with each other and form clumps of fat, or butter grains.
Churning is the process of shaking up cream or whole milk to make butter, usually using a butter churn.
A butter churn is a device used to convert cream into butter. This is done through a mechanical process, frequently via a pole inserted through the lid of the churn, or via a crank used to turn a rotating device inside the churn.
churning process is used to separate the butter from the milk. Moving the milk or curd continuously with skimmers produces butter . This process is called churning. Generally Shaking milk or curd in a jar bottle for an hour also produces butter.
Churning (or Centrifugation): It is the process of separation of the lighter particles of a suspended solid from a liquid. For example, to obtain butter from the curd or milk. Condensation: The process of conversion of water vapour into its liquid form is called condensation.
Small yellowish clumps of butter will start to appear. Keep churning until you see two distinct substances in jar: thin white buttermilk and thick clumps of yellow butter. This should take around 8-10 minutes.
Butter churners like this one were used in many dairy farms in the 19th century along with the milking stool, butter pats and butter prints. It is made of three parts - the churn, the plunger/dasher and the lid.
Definition: Churn is a measurement of the percentage of accounts that cancel or choose not to renew their subscriptions. A high churn rate can negatively impact Monthly Recurring Revenue (MRR) and can also indicate dissatisfaction with a product or service.
It should take about 30 minutes total to make butter in your stand mixer. The whisking process itself could take around 10 minutes. Squeezing the milk out of the butter will take another few minutes and rinsing the butter will be another 10 or 15 minutes.

Churning is excessive trading of assets in a client's brokerage account in order to generate commissions. Churning is illegal and unethical and is subject to severe fines and sanctions. Brokerages may charge a commission on trades or a flat percentage fee for managed accounts.
The stomach wall has three layers of muscles. In mechanical digestion the food is churn and squeezed by these muscles in the stomach. Hydrochloric acid helps to break the large particle into liquid. So, that stomach is called a churning machine.
The verb churn means to mix cream until it turns into butter, separating out the buttermilk. You can make your own butter by churning it in a jar if you don't have a churn, shaking heavy cream until it becomes solid.
Shake the cream for 5 to 10 minutes until the butter forms and is sloshing around in some liquid. After a few minutes, it will turn solid and it will feel like nothing is happening on the inside. Just keep shaking until that butter forms.
The ideal temperature for churning butter is around 60-65 F. If the cream is too cold, it is harder for the fat globules to stick together, and if it is too warm the butter will be a little too soft and gloopy. Pour the cream into the glass jar of the churn. Screw on lid.
There are four different types of churn: customer churn, revenue churn, gross MRR churn, and net churn. A low churn rate improves your MRR, customer lifetime revenue, and customer retention rate. A good monthly churn rate for SaaS businesses is below 1%.
The churning of your stomach ensures that partially digested food is broken down into absorbable nutrients.
During churning, air bubbles surrounded by a protein film are formed. As a continuous shear is applied during churning, the milk fat globules will collapse allowing the liquid fat to surround the air bubbles.
Melt butter in 1-quart saucepan over low heat, without stirring, 10-15 minutes or until melted and solids separate from fat. Remove from heat; let stand 5 minutes. Skim off foam. Slowly pour off clear yellow liquid, leaving behind the residue of milk solids that has settled to bottom of pan.
Butter is a dairy product made by churning either fresh fermented cream or milk. It consists of butterfat, milk proteins, and water. This product is solid at room temperature.
What tools and equipment are needed for this? You need a mixing bowl, whisk or electric mixer, spoon or plastic spatula, measuring cups or scales, teaspoons, tablespoons, cooling racks, cake pans, parchment paper and an oven.
Instead of churning in an ice cream maker, pour into a ziptop bag, squeeze out all air, and seal. Freeze, lying flat, until solid. Remove from freezer and break into chunks small enough to fit into the bowl of your food processor or a high-powered blender. Pulse until completely smooth.
- Setting out chilled butter at room temperature for 30 to 45 minutes prior to use gives it time to soften. ...
- Place the butter stick in a resealable plastic bag or between two sheets of waxed or parchment paper, then pound and roll with a rolling pin to flatten and soften.
Don't over-churn your butter. If you do, you will end up losing that lovely yellow color and again your butter will be pale.
If creamed too long the mixture will turn white and, if you use it, will give your baked goods a dense, almost gluey, texture. So, don't leave your mixer unattended and keep an eye on the mixture so you can see when it's ready. Unfortunately, there isn't a way to correct over-creamed butter and sugar.
Place softened butter and sugar into large mixing bowl. Mix, using hand mixer or stand mixer on medium speed 1-2 minutes, or until butter mixture is pale yellow, light and fluffy. Use a rubber spatula to scrape the sides of the bowl once or twice while mixing.
Buttermilk is actually a byproduct of the butter making process. It's the liquid part of the cream that is left behind when the butter solids coagulate during churning.
Inside the churn is a wooden stick, called a dasher. The dasher would be moved up and down to separate the yellow butter fat from the milk fat. Just like churns come in different shapes and sizes dashers can vary too.
Such a machine looks like a container with a couple of paddles in it. They rotate and churn cream, converting it into butter. Paddle churns can be mechanical or electric. The first kind has a hand crank that one has to rotate manually to make the spread.
Now, just so we're on the same page, 5% – 7% Annual churn – the good churn rate – translates to 0.42 – 0.58% monthly churn. This means companies with “acceptable” churn, lose only about 1 out of every 200 customers (or dollars) per month.
The churn rate formula is: (Lost Customers ÷ Total Customers at the Start of Time Period) x 100. For example, if your business had 250 customers at the beginning of the month and lost 10 customers by the end, you would divide 10 by 250. The answer is 0.04.
Churn prevention refers to the strategies companies use to minimize the number of customers and volume of revenue that is lost to different types of churn. Proactive churn prevention helps eliminate potential issues before they occur and keep customers happy as your company grows.
Add a bit of salt to the cream before shaking or mixing (up to 1/4 teaspoon salt per 1 cup cream). Once your butter is churned you can also add in herbs, honey, and other flavorings for some gourmet butter options.

Salting the butter: For 2 cups of cream, add 1/2 teaspoon of sea salt for a fairly salty butter, or 1/4 teaspoon for lightly salted; alternately, leave unsalted. Keeps 2-3 weeks in the fridge or 6 months in the freezer. Once you've whipped up homemade butter, add herbs and flavorings to make compound butter.
Whether you're shaking a jar or churning an old fashioned butter churn, it all works the same way. As you agitate the fat in the milk cream, the fat membranes break open, and the sticky fat will start to clump together into a ball of butter.
The stomach lining contains muscles which physically squeeze and mix the food with strong digestive juices ('churning') Food is digested within the stomach for several hours and is turned into a creamy paste called chyme.
(Kirn is a Scots and Northern English word for churn.) Other names for the dash are dasher-staff, churn-staff, churning-stick, plunger, plumper, or kirn-staff.
From the 1700's to the 1940's thousands of companies made butter churns in a variety of sizes and styles. First used was a plunge or dash churn where the up and down action of the wooden plunger or dasher (a flat wooden circle or cross piece attached to the round wooden handle) agitates the cream.
Figure 2: The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
The stomach muscles churn and mix the food with digestive juices that have acids and enzymes. These juices help break up food into much smaller pieces.
Churning of milk cream to get butter involves a physical change. Here there is no involvement of chemical reaction or no new product gets formed. The principal involved in the given process is centrifugation which turns the milk cream into butter.
When milk cream is churned, we get butter. Here, no new substance is formed. Instead, the fat droplets in milk cream join together to form clumps of fat (butter). There is no chemical change happening here, only a physical change.
Cultured butter vs regular butter.
|Regular Butter||Cultured Butter|
|Contains milk fat, water, and milk solids||Contains more milk fat|
|Good source of sugar, protein, and fat||Good source of fat and broken down sugars and protein|
Buttermilk is actually a byproduct of the butter making process. It's the liquid part of the cream that is left behind when the butter solids coagulate during churning.
To make butter, the cream is agitated (stirred up) so that the fat molecules get shaken out of position and clump together. Eventually, after enough agitation, the fat molecules clump so much that butter forms.
Heat (thermal energy), light (radiant energy), electrical, and physical (kinetic energy) are familiar kinds of energy. In this activity, potential (stored) energy gets turned into physical, or kinetic energy, (shaking of cream) and ultimately turns the cream to butter.
- Pour the cup of heavy whipping cream into a jar that can hold at least 3 cups.
- Place the lid on the jar tight.
- Shake the jar for about 20 minutes.
- Observe the jar as you shake. ...
- Pour the buttermilk out of the jar. ...
- Continue shaking and pouring out buttermilk until buttermilk stops forming.
Definitions of butter churn. a vessel in which cream is agitated to separate butterfat from buttermilk. synonyms: churn. type of: vessel. an object used as a container (especially for liquids)
The salt content is usually between 1.5%-2%, depending on the brand. Salt not only adds flavour, but it acts as a preservative giving butter a longer shelf life of about 3 months. Using salted butter is ideal for all types of cooking and is a great way to add extra flavour, with no need to add extra salt.

The grains of butter are washed and kneaded : washed in pure water to remove the buttermilk and kneaded to finally obtain astable emulsion (that is 16% water in suspension in 82% fat) and to give the butter a nice smooth and uniform texture.
It is possible to overmix the butter and sugar. If you overmix, however, the butter will separate out of the mixture and it will be grainy and soupy, so be sure to stop once your butter becomes light and fluffy.
Always buy heavy cream or whipping cream for churning butter. Any brand will do. You need the higher fat content. Heavy cream is approximately 40% butterfat and 60% milk solids and water.
