What are the important things which help you select the best cream separator?

In this blog, we are going to take you through some of the insightful tips to select the best cream separator for your dairy plant.

  • Cream separator capacity is not the actual amount of milk that can be processed

When the manufacturer tells you the cream separator performance like 100litres per hour, it does not mean that it can separate the 100 liters of milk. With time, the separators are going to get clogged with fat, grass particles, and whatnot. It is the reason, after 45 minutes of work the separator needs to be stopped, unwind the drum, and then you need to stop it. It is just going to take 15 minutes. Ask the manufacturer to tell you better what needs to be done while using the machine.

  • Plastic is not always the bad thing

Well, the use of plastic in dairy equipment is helpful in different ways you might have not even thought of. No doubt, the plastic can break easily and it won’t smell the best. Many people prefer metal.

However, plastic is different and it is the perfect option & its use is not going to bother you in any sense. This option is cheaper and it will work best also.

  • Check the parts which come in food contact

The ideal material choice for all these options is stainless steel. Apart from that, you can opt for anodized aluminum. After that, you can choose aluminum and polycarbonate. You should not opt for the tin-plated parts as the material can peel off and starts getting rusted which affects the entire milk quality. So, choose wisely so that the end-user gets quality milk and dairy products.

  • Type of engine present in the machine

Well, there are 2 types of engines which come with a brush and without a brush. With brushless motors, there is the presence of electronics which helps to control the engine speed and it can perfectly adapt the voltage surges.

Engines with brushes are simpler and there is no presence of electronics. Moreover, it even allows you to change the speed of operation which can work great for separation.

Ideally, the motor with brushes is a preferable option as they are safe and there is no need for much electricity in it. So, the problem of getting the machine broken down is reduced.

  • Is there availability of fixing hooks in the separator?

Fixing crates are needed for safety purposes so that the separator is fixed to the milk container. If someone hits it by accident, the separator will not break and the surrounding objects are not going to get damaged. The milk container has to fix hooks attached to it which increases the stability.

What are the topmost things for selecting the quality cream separator?

Given below are the top things which can help you select the premium quality cream separator along with other dairy equipment:

●     Cream separator capacity is not the actual amount you can process

When you get to know that it can perform at 100 liters per hour, this does not mean it can separate 100 liters of milk with this machine. Over time, the cream separator can get clogged with milk fat, solid elements, and particles of grass which can be found in milk. So, keep in mind after 30 minutes of work it needs to be stopped completely, unwind the drum, and then wash it.

The entire process is going to take 15 minutes. So, with 100 liters per hour of capacity, you can separate around 75 liters of milk because 15 minutes are for cleaning the cream separator’s drum.

●     Plastic is not the bad thing always

Many people worry about the quality of the end product when they see that some parts are being made of plastic. No doubt, plastic can be broken easily and they do not even smell good. So, many people prefer to buy a separator which is made of metal.

Plastic is different. Polycarbonate is one material that is used in expensive models. Additionally, it is not oxidized like aluminum and it is cheaper. Buying a plastic cream separator is the best choice you can make.

●     Consider the materials which will come in contact with food

While looking for a cream separator, you need to pay attention to the parts which will come in contact with milk. The following parts can be there like a float chamber, a milk container, a flota drum, skimmed milk outlets, and cream. So, the ideal choice of material for all these parts in stainless steel 304.

Another choice for the quality is anodized aluminum. After that comes the food polycarbonate and aluminum. Plain aluminum is not the best choice because it can not come in contact with milk which is not healthy.

●     What type of engine is present inside?

2 types of engines are there which are brushless one and a collector. Brushless motors are engines that have the electronics present inside it and they regulate the engine speed and then it can adapt the voltage surges.

Collector engines are simple because there is not any type of electronics in it and they have carbon brushes which can change the operating speed depending on the voltage change.

Brushless motors are a preferred choice as their resource is much greater as compared to the collectors. Collector motors are considered safe because there is less use of electronics inside which can be broken down and affect the working of machinery.

●     Selecting the right voltage

Mainly there are 2 voltage standards: 115V and 230V. You need to be extremely curious about it and find about the standards used in your area. Otherwise, connecting 230V to 115V is extremely slow, and if 115 V to 230V it is not safe at all. So, make sure the right voltage is selected while buying the separator.

What is a milk separator and explain the working of milk separators in a dairy plant?

Milk separator is a cream extracting machine from all milk. The whole milk is then split into fat and skim milk. Cream and skim milk have various densities and therefore appear to be distinguished by the influence of severity. You should check for yourself: you can set the cow’s milk out for 24 hours to see if it settles on top. Milk separator is additionally known as a cream separator.

So, how is a centrifugal milk separator functioning?

Using centrifugal force it enhances the separation of the milk. A centrifugal milk separation unit has conical disks revolving in a bowl or drum at a speed of 6,000 to 10000 revolutions a minute, depending on the form. The operating theory of separation is this.

The centrifugal force travels into the holes of the disks as entire milk is inside of the vessel. The fat globules of the milk travel to the middle of the drum and the condensed milk hit the outer edge as they are clearer. That is how cream removal works. A single separator disk stack operates like this. The idea was the same irrespective of whether it is a limited model for home usage or a commercial model with a large dairy.

Key characteristics that are worth looking at the milk fat separator.

Efficiency-: The good quality centrifugal milk separator system is expected to remove skim milk only 0.01% to 0.05% butterfat.

Ability-: The ability of a separator is the volume of milk it is willing to absorb in an hour.

Power supply-: Separators may be electrically driven or manually controlled. Now available are hybrid models.

Specific considerations influencing milk separation

Milk temperature: The optimal temperature for milk separation is about 40 degrees C. The boiling of milk past 45 degrees Celsius is not advised. Different volumes of milk butterfat: more milk butterfat implies more cream after separation. With a milk separator, the average volume of butterfat is around 35% to 40%. It is usable.

Price of the milk: Tiny separators have no tank for self-cleaning, as the big centrifuges do. Instead, through 30-90 minutes, the cup must be carefully washed to extract butterfat, slime, and lateral matter. The precise time of continuous separation also depends on the consistency of the milk.

Our recommendation: Two bowls should be used. You will switch between the milk centrifugation without interrupting it. Another bowl works when you rinse it.

Factors that do not impair the separation of milk

Organic versus pasteurized-: When the milk is pasteurized, the cream is made from fresh milk.

Cow vs goat-: A weaker microstructure owing to its fatty globules and is usually smaller (compared to animal milk). So the cream of the goat grows even later than the cream of the cow. But with dish bowl centrifuge, all forms of milk are fairly well separated.

How Cream Separators Are Necessary Today

With the growing milk industry, we have witnessed many things come to pass. The introduction of advanced dairy machinery has seen milk farmers dance to the best tunes ever. The machines have lessened the workload, hence attaining more from the activities.

What is a Cream Separator?

In the past, milk farmers used to milk their cows normally 2 or 5 cows in the morning. They could use manual labour or cans to separate the cream from the milk. This process was easier with those who had a few cows, but for those who had many, the milk had to be taken somewhere else to separate the cream from the milk. It could cost someone a lot of money one month to another.

Therefore, a cream separator is a machine or device that extracts cream from fresh/whole milk which results into skimmed milk.

The current studies show how cream separators are widely purchased by both dairy farmers and milk plants. The same machines are also required in factories, mostly associated with milk drinks and products.

The current market is promising due to the fact that there are different consumer preferences that have to be met by the dairy industry. There is high demand for skimmed milk, cheese, butter, yogurt, and much more that require separating cream from milk.

Advantages of Cream Separators today

Applying Centrifugal force is one of the best ways of separating cream from milk. The procedure that is currently used by big farms and milk plants is ideal in a unique way due to the fact that less than 1% of the cream is left behind.

The cream separators are in different models and types, but the advanced electric cream separators offer the following benefits

  • Remove Tuberculosis germs
  • Quality milk
  • Remove odours from the milk
  • Provides better cream
  • Purifies the milk
  • Improves aeration
  • Reduces workload
  • Effective from every angle
  • Fast
  • Improve the milk standards

The modern cream separators use a centrifugal force which is fast and effective. The electric cream separator consists of a frame where the rotor is located. The frame also harbors an electrical drive and with a mere press of the button, the milk will be centrifuged to separate the cream from the milk.

This process allows more litres of milk to be centrifuged on a daily basis. An electric cream separator can also be used at home for a number of spinning purposes.

However, also manual or semi-automatic cream separators can be purchased to help at the farm. Usually, depending on the usage and the amount of milk collected in a day, the cream separators are available in various sizes and models.

The cream separator market serves a large market and has helped many farms separate milk for different purposes. Cream separators are manufactured and supplied by NK Dairy Equipment at an affordable rate. They are normally in stainless steel, highly robust plastic and aluminium alloys.
