How many discs are in a cream separator?
120 discsThere are up to 120 discs arranged one over other, angle of inclination being 45-60° to the horizontal. Outward diameters are 200-300 mm. Disc are generally made up of stainless steel and wall thickness will be 0.4 mm. The number of discs in a cream separator relates to its capacity.Oct 9, 2012
What happens when cream is separated from milk?
It will decrease as whole density of milk will decrease when cream is separated as it is a part of milk. The density changes due to differences in the density between cream and milk. Cream is lighter than water and milk is heavier than water. The average density of whole milk could be close to 1.024g per liter.Oct 29, 2010
How did the cream separator change farming?
For thousands of years cream was separated by the slow and inefficient method of pouring raw milk into various containers and letting gravity move the less dense cream to the surface where it could be skimmed off.May 1, 2008
Who invented milk separator?

What is the working principle of cream separator?
Separation of cream is based on the principle that milk fat,because of its lower density is lighter than the skim milk portion. Hence it tends to rise to the surface and separates from the serum (skim milk). This principle is applicable to both gravity method and mechanical method of cream separation.
Why was the cream separator important?
A milk or cream separator is a device that removes cream from whole milk. As a result, the whole milk is divided into cream and skim milk after separation. Cream and skim milk have different densities and therefore they tend to get separated under the impact of gravity.Sep 27, 2018
How fat is separated from milk?
Centrifugal separation is another technique commonly used to separate fat from milk to make skim milk. As suggested by the name, centrifugal separation relies on the use of a centrifuge, which spins containers of milk at forces as high as 5,000 to 10,000 times that of gravity.
How much is a cream separator worth?
The cost of a cream separator can vary from two or three hundred dollars to twenty or thirty dollars, depending upon the size of the separator and whether or not all the original parts are included.
How milk is separated from cream?
The process by which cream is separated from milk is called centrifugation. Well, Centrifugation is a process where a mixture can be separated through spinning. The process is used to separate skim milk from whole milk, from the big separators.
How is milk skimmed?
So how is skim milk made? Traditionally, the fat was removed naturally from milk due to gravity. The quicker, modernized way of making low-fat and skim milks is to place the whole milk into a machine called a centrifugal separator, which spins some or all of the fat globules out of the milk.
How does a Delaval cream separator work?
The milk-cream separator. At that time, cream was separated from milk simply by the milk being left to stand until the fat floated up to the surface and could be skimmed off. The milk-cream separator was based on a simple principle — a rapidly rotating container creates centrifugal force.
What does milk separate into?
Milk contains two types of proteins: casein and whey. Cheese is made the same way — by curdling milk — except the milk is curdled on purpose. Most cheese is made in factories. After milk is poured into big vats, a “starter culture” of bacteria is added to convert the lactose into lactic acid.
How is cream produced from milk?
Cream is a dairy product composed of the higher-fat layer skimmed from the top of milk before homogenization. In un-homogenized milk, the fat, which is less dense, eventually rises to the top. In the industrial production of cream, this process is accelerated by using centrifuges called "separators".
Who invented the milk separator?
In 1878, Gustaf and his business partner Oskar Lamm patented the invention. Gustaf was awarded the Wallmark Prize from the Royal Swedish Academy of Sciences for his invention. The milk separator won first prize in a number of international exhibitions and in 1883, Gustaf and Oskar Lamm founded the company AB Separator (now Alfa-Laval).
What is milk separator?
The milk-cream separator was based on a simple principle — a rapidly rotating container creates centrifugal force. Rapid rotation causes heavier substances to be pressed out toward the walls of the container while lighter substances are collected in the middle.
How does a steam turbine work?
The idea to use water vapour as a propellant was not new. The steam turbine was actually described 2000 years ago by the Greek mathematician Hero. The turbine converts the kinetic and thermal energy of water vapour into mechanical rotary motion. The nozzle of the turbine blows steam onto the wheel and makes it rotate. Gustaf was awarded a patent for his steam turbine in 1883. At the same time, the Englishman Charles Parsons also constructed a steam turbine. Gustaf´s steam turbine, with the — for that time — astounding rotation speed of 30,000-40,000 revolutions per minute, quickly became a best-seller. The company “AB de Lavals ångturbine” was founded in 1893 (now known as STAL-Laval turbin AB). Today, steam turbines are used in power stations to run electric generators.
What was Gustaf de Laval's most famous invention?
Gustaf de Laval was a productive inventor with vision. The steam turbine, the milk-cream separator and the milk-skimming machine were his most famous inventions. Gustaf was not quite as good at handling his finances, however, and died in extreme poverty.
How long did the Lavals milk machine last?
The AB de Lavals Laktator company survived for two years. In 1897, the company was dissolved and the employees dismissed. There are several other similar stories.
What is the de laval nozzle?
The de Laval nozzle. The de Laval nozzle is an hourglass-shaped tube that accelerates gases moving through the tube to supersonic speeds (i.e. faster than the speed of sound). The same principle is used in steam turbines, modern rocket engines and supersonic jet engines.
How long did it take Gustaf to build a ship?
Gustaf wanted to build a ship that would cross the Atlantic in ten hours. A prototype was built and a test run was conducted on Lake Mälaren. The hull contained a high-pressure air machine that forced the air out of small holes in the hull.
Childhood and Studies
The Quest For Success
- The young Gustav was passionate about his ideas. He would achieve great things and be Sweden´s saviour. This attitude characterized his entire life. Gustaf´s first project was a glass factory where glass bottles were to be formed using centrifugal force. But market prices on bottles fell and the project ended in a financial fiasco.
Two World-Renowned Inventions
- In 1874, Gustaf began working as an engineer at the Kloster ironworks in Dalarna. It was there that he got the idea for two inventions that would make him world-famous.

Setbacks
- Gustaf didn’t live in the now. It didn’t matter to him if his debts mounted. New ideas and new inventions were the only things that were important. He dreamed of helicopters and fast ships. Nobody could control him and his business partners left him one after the other. The money that he made on the success of his milk-cream separator was swallowed up by other projects. One f…
