Food industry

In cattle rearing, the animals are frequently fed with wheat starch concentrate. To obtain a higher protein content, a cattle fodder manufacturer adds surplus wheat starch concentrate to the animal food production from an industrial bakery. This involves wheat waffles and brown pastry sheets which are sandwiched around a milk preparation.  

They are then added uncrushed to the wheat starch concentrate. An auger feed conveys the medium to the Boerger Multicrusher. After the initial rough chopping phase, the Boerger Rotary Lobe Pump conveys the medium to be finely chopped in the Boerger Multichopper plus. The speed of both Boerger machines is regulated and synchronized.  

In selecting the chopping unit and pump, the animal fodder manufacturer was impressed with excellent results, especially with the ease of maintenance for Boerger products. The Rotary Lobe Pump, Multicrusher and Multichopper are all designed so that maintenance can be carried out by in-house personnel on site at the animal fodder manufacturer's by simply undoing a four bolts.

A food manufacturer produces syrups, concentrate, vitamin combinations and emulsions. These raw materials are used in the production of alcohol-free beverages. Liquid sugar is also added to the production process. Different doses of the liquid sugar are fed into a mixing tank depending on the type of drink. 

To do this, the beverage manufacturer has been using a Boerger Rotary Lobe Pump since 2003. The customer adds the required amounts of liquid sugar using a control panel. A control unit combined with a frequency converter regulates the speed of the Boerger Rotary Lobe Pump so that the liquid sugar is pumped out of the storage tank into the mixing tank in doses. The customer is very pleased with the long service life, the low wear and the reliability of the Boerger Rotary Lobe Pump.

Glucose syrup is used as an ingredient in countless food products and beverages and is one of the most important products in saccharification. One of Europe's leading fruit and vegetable producers uses a Boerger Rotary Lobe Pump for conveying glucose syrups. The glucose syrup is mixed with other ingredients and then used as a conserving medium for fruit and vegetable preservatives. 

The Boerger Rotary Lobe Pump transfers the glucose syrup from a storage tank into the mixing unit of the production process. 

When selecting a suitable pump, it was essential for the food manufacturer to have one which could handle highly viscous media, guarantee a long service life and be easy to maintain. The preservative manufacturer opted for a Boerger Rotary Lobe Pump.

At a slaughterhouse, pigs and cattle are killed for food production. The slaughterhouse uses a Boerger Rotary Lobe Pump to transfer animal blood.

Once the animals have been slaughtered, the blood drains off in the bleeding zone. A large stainless steel basin is there to collect all the blood flowing from the incision. The Boerger Rotary Lobe Pump conveys the blood from a recess in the basin to a storage tank.  

The slaughterhouse was previously using a membrane pump to do this.  However, the ear tags from the animals kept getting stuck between the membranes and causing damage. The operators at the slaughterhouse sometimes had to open up the membrane several times a day, which cost time and money. The customer is now highly satisfied with the Boerger Rotary Lobe Pump. Alongside the pump's resistance to solids and the operation stability, the customer was particularly impressed with the low maintenance.

In the cement industry, many different materials and substances are used to fire the furnaces. A Japanese cement manufacturer fires its rotary kilns by incinerating fish. In fact, this is the by-product and remains of fish which are not sold and not economically viable.

The fish have to be chopped so that they can be burned effectively. The Japanese cement manufacturer was looking for a chopper to do this. After performing various tests with products, they decided on a Boerger Multicrusher. 

The customer was impressed with the excellent chopping yield and particularly with the Multicrusher's ease of maintenance. Wear parts could be replaced by the customer's in-house maintenance staff directly at the installation site without dismantling any pipe or drive systems.

A major German brewery was looking for a pump to transfer liquid containing diatomite. The brewery uses diatomite as a filtering aid. The yeast and turbidity are filtered out of the beer in three phases. In the separation process of the centrifuge, the diatomite filtration is performed followed by filtration through cellulose layers.  

To pump the diatomite filtered liquid mixture to a collection tank, the brewery needed a pump. It was important for the brewery to have a robust, high performance pump. A Boerger Rotary Lobe Pump was chosen. 

The casing of the Boerger pump is made of duplex stainless steel. Due to the extremely abrasive medium, the pump is fitted with replaceable casing protection plates and liners. The Boerger Rotary Lobe Pump has been operating at the customer for almost 10 years now. Maintenance work can be performed in a matter of minutes by the brewery's own staff thanks to the low maintenance Boerger pumps.

A sugar beet manufacturer was looking for a high performance pump to transfer cooked sugar beet. The pump needed to be resistant to solids and able to convey high-temperature media.  It was essential for the manufacturer to have a pump with high reliability. The customer opted for a Boerger Rotary Lobe Pump in stainless steel.  

Before the sugar beet is transferred to two stainless steel tanks by an auger unit, soil and other impurities are removed. The beet is heated to 105 degrees for approx. 7-8 hours in the stainless steel tanks (excess pressure 0.5 bar – so that it cannot start to boil). After the cooking process, the beet slurry containing large pieces of beet is fed to the Boerger Rotary Lobe Pump through a special auger.

The Boerger pump conveys the unpurified beet slurry into a tank. Then a two-phase decanter is fed by another pump and pure beet substrate is formed.

Technical data

A major German brewery sought a stainless steel tank for storing the process water needed in the beer production. The brewery had received several offers from various providers. They decided to buy a Boerger stainelss steel tank with a volume of 856 m³. 

The Boerger stainless steel tank consists of individual segments (1.5 x 3.0 m) which are bolted to one another. This system offers distinct advantages over a welded stainless steel tank. Besides the intrinsic value based on it being easy to disassemble and relocate somewhere else, the bolted Boerger stainless steel tank is far more reasonable than a welded tank from one of the competitor's .  

The tank also has a stainless steel roof and floor. As the brewery wanted to clean the tank interior once a year, the Boerger stainless steel tank was also fitted with an entrance flap which can be bolted back on firmly after use. The tank takes less than a week to assemble.

A system supplier for preparation and further processing of organic residues was looking for a compact and robust pump for conveying macerated intestines. Due to the consistency of the intestines it was important that the pump could convey media with high portions of solids. The customer opted for a Börger Classic PL 300 rotary lobe pump. The customer is very satisfied with the reliability and the efficiency of the Börger rotary lope pump.

Technical data

A leading provider of gelling and thickening agent for the food and beverage industry processes large quantities of lecithin which is supplied to the company in tanker trucks. Previously a gear pump was used to empty the tanker trucks. As the gear pump had a very high energy consumption but only a moderate flow rate, the customer looked for an alternative pump. In order to be able to use the pump at another location in case of emergency, the Börger rotary lobe pump was built as a hand cart pump. Due to its compact design, the pump can be pushed to the required location like a wheelbarrow. The pump is driven by an electric motor.

Technical data

Lecithin is extracted from the raw vegetable oil in the degumming process of an oil mill by means of a separator. The up to 90 °C hot lecithin mixture is transported to a storage tank. The Börger ONIXline pump conveys the mixture with a viscosity of up to 5,000 mPas in a 35 m high tank where it is inserted by means of nozzles. In the process, a pump pressure of approx. 10 bar is created. More or less of the lecithin mixture has to be added depending on the liquid content of the press cake. The pump is operated by a frequency converter. This way, the speed and flow rate can be varied and adapted to the liquid content of the animal feed. The bleaching earth contained in the lecithin mixture is the reason why the medium is abrasive.
