Packaging Vacuum Applications

Vacuum PackagingVacuum pumps can play a critical role in packaging processes, as well as in packaging production.  Packaging can be efficiently and precisely formed, thermoformed and coated using vacuum techniques. It can also be moved, transported, opened and sealed by vacuum. During the packaging process, goods to be packaged can be fed and inserted with the aid of vacuum.

Using vacuum in food packaging helps to keep food fresh longer – with no loss in quality. The use of MAP (modified atmosphere packaging) for fresh food products maintains the appearance, freshness and flavor.

Which Busch vacuum solutions should we use for packaging applications?

R 5 series vacuum pumps are the ideal vacuum generators for packaging. They use the proven rotary vane principle and are regarded as the vacuum pump of choice for this market. We also offer oil-free technology for a wide range of packaging applications – such as the highly energy-efficient Mink claw vacuum pumps and the dry running rotary vane vacuum pumps of the Seco series. For example, Mink vacuum pumps are used to transport the foil that creates the tubular bag during the packaging process, whereas Seco vacuum pumps are primarily used in handling or holding processes.

Degassing Vacuum Applications

Busch Degassing

In many industries the degassing of liquid, paste-like and moist products is one of the most important applications of modern vacuum technology. Gases, vapors and moisture are extracted under vacuum from the processed material, improving product quality.

The degassing of plastics during extrusion is one example. Vaporized moisture and gases driven off by the melting process are extracted directly from the extruder screw zone, significantly improving the structure and physical properties of the product.

We offer a standardized range of vacuum pump systems designed specifically for extrusion processes, which include separator/filter units to condense the extracted vapors and gases. Our project engineers will calculate your requirements and recommend a system precisely matched to your extruder throughput and raw material.

Which Busch vacuum solutions work the best for degassing processes?

We offer vacuum solutions for all degassing processes. Our customers rely on our high-quality products and decades of experience in all areas of degassing. For degassing applications in the food production industry, we offer a wide range of vacuum pumps that can be optimized for any process and meet the highest hygiene standards.

One area in which vacuum systems are subject to special requirements is steel degassing. The high vapor/gas temperatures and elevated dust levels present particular problems. Our systems can operate in this hostile environment, as they are completely dry running and use the latest technology. The energy efficiency levels of our systems are superior to those of our competitors.

Depending on the technical requirements of your degassing process, R 5 rotary vane vacuum pumps, Mink claw vacuum pumps or COBRA screw vacuum pumps are the most suitable models.

Drying Vacuum Applications

Busch Drying application

It is hard to imagine many industrial markets operating efficiently without vacuum drying processes. The liquid contained in the processed materials is evaporated by pressure reduction and extracted as vapor.

Vacuum drying is faster, gentler and more energy-efficient than heat drying. It is particularly suited to drying processes for chemicals, pharmaceuticals, food and other applications in which excess heat would destroy or degrade the product.

For example, in fruit concentrate production or the freeze drying of coffee or fruit, vacuum drying maintains product consistency and preserves vital ingredients such as vitamins and flavors.

Vacuum drying is especially suited to the drying of products with a large surface area, such as plastic granules or other hygroscopic materials. Vacuum is also used to dry industrial components.

Which Busch series are particularly suited for drying processes?

Busch COBRA vacuum pumps are recognized as the pump of choice in the chemical and pharmaceutical industries, where a large number of drying processes are required. They are used extensively to generate high vacuum levels in one stage operation.

COBRA screw vacuum pumps are the ideal choice for drying processes, as they exhibit a high tolerance to humidity and are completely free of operating fluids. The absence of operating fluids eliminates contamination of processed materials.

If there is a risk that explosive vapors may be produced during the drying process, a wide range of explosion-protected (ATEX) vacuum pumps is available to handle such materials. These pumps meet all national and international safety certification requirements.

We not only offer vacuum technology for drying processes, but we also supply separation units that condense extracted vapors and recycle them as liquids. As the vacuum pumps are dry running and use no operating fluids, contamination is eliminated and if required, the liquids can be reused immediately.

Our large product portfolio is designed to cater to a broad spectrum of drying processes. The applications range from small rotary vane vacuum pumps to large vacuum systems and turn-key vacuum installations.

When drying ceramic substances or construction materials such as bricks or tiles, liquid ring and rotary vane vacuum pumps are used. Dolphin liquid ring vacuum pumps represent a particularly efficient and durable way of extracting humid gases and vapors, as the only operating fluid required is water.

A special version of our R 5 rotary vane vacuum pump exhibits high vapor compatibility so that the water vapor does not condense within the pump and extracted moisture does not come into contact with the material to be dried.

Both technologies are suitable for the particular requirements of these processes and are available in many different sizes and variants.

COBRA screw vacuum pumps easily extract all types of vapors at low pressure levels and use a dry running operating principle. When combined with Puma or Panda Vacuum-Boosters, they can be used in vacuum systems for drying processes.

The R 5 or Huckepack rotary vane vacuum pumps and Dolphin liquid ring vacuum pumps have proven themselves worldwide in the drying of ceramic and construction materials.

What are some Busch vacuum technology drying process examples?

  • Freeze Drying (food)
  • Powdered Milk Production
  • Sludge Drying (wastewater industry)
  • Wood Processing Drying
  • Drying of Plastic Granules
  • Ceramics Drying
  • Components Drying

Holding/Lifting Vacuum Applications

Busch Handling Application

It’s difficult to imagine modern production processes without using vacuum technology for the holding, transporting or handling of goods. How else would it be possible to stack cardboard so quickly and reliably, move glass panels, hold wooden components for milling, or load heavy items such as paper rolls, sacks or even bricks?

The idea is simple and ingenious. A suction cup, vacuum plate or vacuum table is used to apply suction and hold an object firmly. This is an extremely effective method for moving, transporting or clamping objects.

In automated production processes such as furniture manufacturing, the component parts are moved by vacuum through the entire production line. The process begins with the delivery of wooden panels that are fed to the initial processing machine by a robot fitted with a vacuum suction device. The panels are held by vacuum and processed on this machine before being transported to the next processing stage by another vacuum gripper. At the end of the production line, a robot automatically stacks the crated furniture items on pallets.

In printing shops, vacuum is used to transport individual sheets of paper. They are drawn into the printing machine by vacuum, where they are fed through the individual printing stations by rollers using vacuum before being stacked again after printing. The paper is also fed through all the subsequent processing machines using vacuum.

Which Busch vacuum pumps work best for holding and handling goods?

Due to the numerous areas of application and tasks involved in holding and handling goods, the requirements for vacuum generators could hardly be more varied. For instance, dry running and oil-lubricated rotary vane vacuum pumps from the Seco and R 5 series, Samos side channel regenerative blowers, Mink claw vacuum pumps or Tyr rotary lobe blowers may be suitable.  If the vacuum supply of the operation is centralized, individual vacuum systems may be more appropriate.

We supply the appropriate vacuum technology for all handling devices. For example, extremely energy-efficient and low-maintenance Mink claw vacuum pumps are used for clamping components to CNC machining centers used for woodworking. The wooden items are held in place firmly and securely for processing.

What are some Busch vacuum technology holding and handling examples?

  • Automated materials handling – In production processes
  • Palletizing – Stacking of packed units on pallets
  • Loading and unloading – Of ships, vehicles and other means of transport
  • Clamping – To woodworking machinery
  • Packaging – Of an extremely wide range of articles in cardboard boxes or other packaging
  • Paper Transport – For printing and processing machines in the printing industry
  • Pick and Place – In the electronics, food, parts packaging and many other industries

Distillation Vacuum Applications

Busch Distillation

Vacuum distillation is an important process in the pharmaceutical and chemical industry and has applications in many other sectors including beverage and food production. Another example is crude oil refining where two distillation processes are required due to crude oil containing heavier and lighter hydrocarbons with different boiling points. After atmospheric distillation, a second distillation is carried out under vacuum to separate heavy hydrocarbons at lower temperatures, minimizing thermal cracking and the creation of unwanted by-products.

Our wide range of vapor-compatible, corrosion-free vacuum equipment is ideal for use in distillation processes. We offer ATEX (explosion-proof) models for use with flammable vapors, gases and liquids.

Which Busch vacuum pumps are best for distillation processes?

COBRA screw vacuum pumps are ideal for distillation applications as they generate high vacuum in a single stage. As these pumps run without operating fluids, they are able to extract media as a vapor without contamination. As a result, the media can be reused after condensation. An extensive range of sizes and models are available, including explosion-proof versions (ATEX).

Dolphin liquid ring vacuum pumps are extremely robust vacuum generators that are used in a number of distillation processes. They can be supplied in a wide range of series, sizes and material of construction options to suit specific applications.

Huckepack rotary vane vacuum pumps have been used in distillation processes for more than 50 years. These two-stage vacuum pumps have a simple and proven design and are fresh-oil lubricated. The operating fluid is supplied to the compression chambers in minimal quantities. Process-compatible fluids can be used.

Oil-lubricated R5 rotary vane vacuum pumps may also be suitable for use in distillation processes.

What are some Busch vacuum technology distillation processes examples?

  • Crude Oil Distillation – Used to separate out the individual hydrocarbons
  • Solvent Recovery – Used to recover solvents from a process medium
  • Vacuum-supported Distillation – In pharmaceutical or chemical applications

Forming/Pressing/Laminating Vacuum Applications

Busch Forming Application

Forming, pressing and laminating with vacuum are popular processes in many branches of industry and in manufacturing technology. These processes are used to join a large variety of materials together or form them into a specific mold.

For forming, it is important that a clearly defined vacuum is used to bring the material into the mold. An established process and one that is used for many products is thermoforming, which is used to shape plastic foils. For this process, plastic foils are heated to soften them. Vacuum is applied through the mold. This pulls the foil, which has been softened by the heating process, into the mold. Once the foil has cooled down, it holds the shape of the mold. This method can be used to create packaging for food products and other commodities, and even preformed plastic forms for garden ponds.

Pressing with vacuum is used in the wood industry, for example, when several layers of wood are glued together and mechanical pressing cannot be used because of the geometric shape. Vacuum can also be used to attach veneers or to fix synthetics to wooden profiles, for example onto kitchen fronts.

Laminating under vacuum is a process that is used to join different layers of materials together, and one that is commonly used in semiconductors and the electronics industries. Solar modules, flat screens and smartphone displays are created in this way.

Which Busch vacuum solutions are best for forming, pressing and laminating applications?

State-of-the-art R 5 rotary vane vacuum pumps have been proven in forming applications with many years of successful operation.

The energy-efficient Mink claw vacuum pumps can be used for pressing when low vacuum is acceptable, in producing furniture for example. If higher vacuums are required, R 5 rotary vane vacuum pumps are the first choice.

COBRA screw vacuum pumps are the preferred vacuum pumps for laminating processes in the production of solar modules, flat screens and smartphone displays because they can discharge leaking gases and vapors without interference.
