Application

Vacuum in filling and sealing

Before filling, the container is evacuated ā€“ the bottle before the beer, the can before the preserved food, the battery cell before the electrolyte, the gas cylinder before the gas. According to Leybold, evacuation ensures clean, dry and bubble-free filling; according to Atlas Copco and Leybold, beer bottles are evacuated before CO2 flushing so that little oxygen remains in the beer. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it ā€“ 361 models from 5 manufacturers.

  • Evacuation before fillingLeybold: before filling with gas or liquid, the container is evacuated so that filling is clean, dry and bubble-free. Becker names the evacuation of tubes, bottles and containers during filling.
  • Beer bottlesLeybold: bottles are evacuated several times and flushed with CO2 to keep the oxygen low ā€“ with DRYVAC up to 80,000 bottles/h. According to Atlas Copco, the bottle is evacuated against oxidation before CO2 flushing and filling (GHS VSD+); Busch names DOLPHIN.
  • ElectrolyteLeybold: repeated evacuation and partial filling for complete wetting, DRYVAC down to min. approx. 0.01 mbar. Busch: evacuate the cell, then fill it under vacuum (R5 RA, COBRA NC/NX, MINK MM/MV); Pfeiffer Vacuum names ACP.
  • Foam and cappingAccording to Atlas Copco, the beer foam separator keeps foam out of the vacuum line (stainless steel, CIP, automatic draining); Atlas Copco names energy savings of up to 40% with it and describes capping bottles under vacuum as airtight against leakage and oxidation.

Operating principle

How it works: Filling and sealing

The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.

  1. EvacuationThe closed container at the filling valve is evacuated ā€“ according to Leybold, beer bottles several times in alternation with CO2 flushing, battery cells down to min. approx. 0.01 mbar.
  2. FillingLiquid or gas flows into the evacuated container: clean, dry and bubble-free (Leybold); according to Leybold, cells are repeatedly partially filled; according to Busch, they are filled under vacuum.
  3. SealingAccording to Atlas Copco, bottles are capped airtight under vacuum against leakage and oxidation and cells are sealed without residual air and moisture; Elmo Rietschle names bottle filling and capping with vacuum control.

Frequently asked questions

Filling and sealing: frequently asked questions

Why are bottles evacuated before filling?

So that no air remains in the container: according to Leybold, the container is evacuated before filling with gas or liquid so that filling is clean, dry and bubble-free. With beer, it is about oxygen ā€“ according to Atlas Copco, the bottle is evacuated against oxidation before CO2 flushing and filling; according to Leybold, it is evacuated several times and flushed with CO2 to keep the oxygen low.

How does beer bottling under vacuum work?

The bottle is evacuated at the filling valve, flushed with CO2 and filled ā€“ according to Leybold, several times in alternation, with DRYVAC up to 80,000 bottles per hour. For this, Atlas Copco names GHS VSD+ (for beer GHS 402ā€“1002) and the beer foam separator, which keeps foam out of the vacuum line; Busch names DOLPHIN, and in its product finder for beverage bottling also HUCKEPACK and R5.

Which vacuum pump for filling systems?

For bottles, Atlas Copco names GHS VSD+ and LRP VSD+, Busch names COBRA, MINK, PANDA, PUMA and R5, Leybold names CLAWVAC, Pfeiffer Vacuum names ACP, COMBI, DuoVane, HiLobe and HiScroll, and Edwards names LR. For cans and preserved food, Atlas Copco names GHS VSD+; for vacuum filling machines, Leybold names SOGEVAC (small) and NOVADRY (large).

Which vacuum pump for electrolyte filling of battery cells?

Leybold names DRYVAC: repeated evacuation and partial filling for complete wetting, down to min. approx. 0.01 mbar. Busch names R5 RA, COBRA NC/NX and MINK MM/MV ā€“ evacuate the cell, then fill it under vacuum ā€“ and Pfeiffer Vacuum names ACP. Becker names evacuating batteries during filling, without a series.

How much vacuum does electrolyte filling need?

For electrolyte filling with DRYVAC, Leybold names min. approx. 0.01 mbar.

Oil-free or oil-lubricated for filling?

Both are named. Dry-running: Leybold DRYVAC, NOVADRY and CLAWVAC, Busch COBRA and MINK, Edwards XDS and GV, Pfeiffer Vacuum ACP, HiScroll and HiLobe. Oil-lubricated: Leybold SOGEVAC, Busch R5, Atlas Copco GHS VSD+, Pfeiffer Vacuum DuoVane. Liquid ring: Busch DOLPHIN, Atlas Copco LRP VSD+, Edwards LR. Leybold assigns SOGEVAC to small and NOVADRY to large vacuum filling machines.

What can be done if beer foam gets into the vacuum line?

For this, Atlas Copco names the beer foam separator as an accessory system for the GHS VSD+: it keeps foam out of the vacuum line, is made of stainless steel, is CIP-capable and empties itself; Atlas Copco names energy savings of up to 40% with it.

Which vacuum pump for vacuum filling machines (sausage)?

For vacuum filling machines for sausage and alternative proteins, Leybold names SOGEVAC for small and NOVADRY for large machines.

How are gas cylinders evacuated and filled?

According to Leybold, gas cylinders are evacuated before filling so that filling is clean, dry and bubble-free. Edwards names evacuating and filling gas cylinders for XDS and GV, and system evacuation and backfilling for the GV series.

Why is sealing done under vacuum?

Atlas Copco names two reasons: capping bottles under vacuum makes them airtight against leakage and oxidation, and battery cells are sealed under vacuum without residual air and moisture. Elmo Rietschle names bottle filling and capping with vacuum control for hygienic filling.

A single pump or a central vacuum system?

A central system in a room of its own keeps noise and heat away from production and matches its output to the demand. Central vacuum systems are planned and built by Eugen Theis Vakuum, a company of the Ehrler & Beck group ā€“ more under Central Vacuum.

Does Ehrler & Beck also supply spare parts and service?

Yes. Ehrler & Beck offers original spare parts and accessories as well as maintenance and repair.
