Dairy pumps

In the dairy industry, pumps must meet many requirements and regulations.

Automatic milk filling plant

dairy pumps are an essential part of milk processing. They are essential for making dairy products such as yogurt, cheese, and cream. Die pumps transport milk from one gas station to the next and thus ensure that production runs smoothly.

In 2019, 33 million tons of milk were produced by around 4.1 million dairy cows. Of this, 31.7 million tons of milk were processed across Germany.

The annual consumption of a German citizen is estimated at 117.2 kilograms per capita.

Just behind the meat industry, the dairy industry is one of the most important industrial sectors of food industry. With the help of 212 companies across Germany, annual sales of 29.6 billion euros are generated.

What does the dairy industry produce?

Die dairy Industry buys chilled raw milk from breeders and farmers. The raw milk comes from either cows, sheep or goats. It is then processed into a wide variety of dairy products. These dairy products can include milk, yogurt, butter, and more. In addition, the dairy industry also converts dairy products into so-called by-products. This includes milk powder, for example. Milk powder is produced by removing all of the water from dairy products.

About our pumps for the dairy industry


What are dairy products?

Exactly what dairy products are is clarified by law in Milk and fat law in connection with the Dairy Product Regulation. There are separate regulations for butter and cheese, for example.

The Milk and Fat Act regulates the interface between the dairies that are supplied and how the products are processed. In addition, it includes delivery and purchase obligations. It also defines the fat content of the products as well as price requirements and regulations with regard to fines.

A distinction is made between treated and untreated dairy products. However, there are also fermented types of milk or products that are extracted from milk components.

Untreated Dairy products include raw milk, preferred milk and raw milk cheese.

To the treated Dairy products include long-lasting milk products, including condensed milk, milk powder, whey powder and cream powder. It also includes a few different types of milk. These types of milk include skimmed milk, skimmed milk, homogenized milk, pasteurized milk or even sterilized milk. In addition, this includes semi-skimmed or low-fat milk, thermized milk, ultra-high-temperature milk, whole milk and ESL milk. ESL milk means extended shelf life - i.e. longer shelf life on the shelf. The shelf life is approximately between pasteurized and ultra-high-temperature shelf-stable milk.

To the group of fermented Dairy products include butter, clarified butter, half-fat butter, cheese, cream cheese, soft cheese, semi-hard cheese, sliced cheese and hard cheese. So-called milk blended products are also fermented milk products. The mixed milk products are also divided into whey, quark, cream, coffee cream, sour-milk products, buttermilk, sour milk, yogurt, kefir, sour cream and creme fraiche.

Bottled dairy products and milk-like products

What requirements must pumps meet in the dairy industry?

In the dairy industry, have bottling plants A big Range of applications and must during pumping process can fulfill a variety of purposes. They must be able to store, collect and unload milk easily, which should save the driver time.

In addition, the dairy industry requires pumps for pasteurization. During pasteurization, the liquids Heated very strongly for a short time. As a result, microorganisms and bacteria can be killed. Die pumping capacity must therefore be able to withstand these high temperatures.

In addition, a type of pump required for filtration systems. This typically involves filtering whey. This allows the whey protein to be extracted. Dairy products contain whey protein on the one hand and casein protein on the other.

To which should the pumping technology Master evaporation in the dairy industry. In the process, the milk is systematically thickened. This is achieved by liquid the moisture is removed. This condition is solved with the help of a vacuum brought about at very high temperatures.

Die pumping systems must be compatible with CIP and SIP cleaning systems. These systems are essential to achieve production safety and a high level of hygiene.

pump manufacturer pumps in the dairy industry must also provide a solution for wastewater treatment. Wastewater can be combined with many solid particles, such as scraps of glass, paper or various fibers, be besieged and soiled. One solution here is a pump type, which is robust, reliable and corrosion-resistant.

Which pumps are suitable for dairy products?

For pumps that you Field of application in the food industry have, there are many regulations.

Breast pumps are subject to particularly strict hygiene regulations. All dairy products are highly perishable and particularly susceptible to germs and bacteria. As a material surface, which is combined with the pumping medium comes into contact is best inox 1.4404.

One EHEDG or else 3A Certifications are indicators of appropriate execution. In addition, for manufacturers of dairy products, a EU regulation 1935/2014 for breast pumps required.

breast pumps should be self-emptying and free of dead space and CIP systems should function without problems.

A surface roughness of less than 0.8 µm makes it difficult for germs to form.

A gentle conveying capacity plays a particularly important role when pumping cheese, as a result of which the consistency can be maintained.

In addition to hygienic centrifugal pumps Are different types of positive displacement pumps very good.

Centrifugal pumps include radial pumps, diagonal pumps, side channel pumps, peripheral gear pumps and axial pumps.

Within centrifugal pumps, also known as centrifugal pumps, an impeller rotates. The resulting suction direction transports the pumped medium into the pump. The operating principle is based on the laws of flowing liquids. Centrifugal pumps only work if Fluid completely fills the pump. Within this liquid, the impeller now rotates and ensures low pressure in the middle of container. This causes the flow moves parallel (axially), vertically (radially), or diagonally.

However, with abrasive liquids with many solid particles or media of high viscosity, positive displacement pumps are more likely to be used.

All positive displacement pumps have one high flexibilityWhat the Aggregate state or the viscosity of the pumped medium. Rotary lobe pumps, screw pumps and diaphragm pumps are particularly popular here.

But also our wobble ring pump combines all features for the ideal furtherance of dairy products. It is gentle on the pumping medium, quick and easy to clean and the sealing systems are easy to change. In addition, it is resource-saving & energy-efficient and CIP and SIP system friendly. It also pumps easily at a temperature of up to 205 degrees Celsius.

Feel free to see for yourself how they work and their benefits. You can find out more about this in our product brochures.
