Application
Boiling, cooking and extracting under vacuum
Under vacuum, water boils at a lower temperature: masses cook, aromas can be extracted and oils deodorised without heating the product strongly. Busch names cooking with less heat and degassing of the mass, Becker the vacuum extraction of aromas, gently at low temperature, Edwards extraction at a lower temperature. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it ā 294 models from 5 manufacturers.

In short
Vacuum cooking and extraction: the key facts
- Less heatBusch: when mixing, preparing and cooking, the mass is degassed and cooked with less heat ā with DOLPHIN, and in the product finder also COBRA, PANDA, PUMA and R5.
- Gentle extractionBecker names the vacuum extraction of aromas, gently at low temperature (VADS), Edwards extraction at a lower temperature (XDS).
- Sugar coatingBusch names sugar coating under vacuum for confectionery with DOLPHIN, and in the product finder also MINK, SAMOS, SECO and TYR; the product data list the series DOLPHIN, SAMOS and TYR for this.
- PasteurisationBusch names pasteurisation and sterilisation for COBRA, DOLPHIN and R5, Edwards cooking and vacuum cooking for LR, Pfeiffer Vacuum mixing, preparing and cooking for HiLobe.
Operating principle
How it works: Vacuum cooking and extraction
The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.
- EvacuationThe filled kettle is closed and evacuated; Busch names degassing of the mass at this stage.
- CookingUnder vacuum, the water boils at a lower temperature: Busch names cooking with less heat, Becker and Edwards extraction at low and lower temperature respectively.
- CondensationThe vapours are condensed in the condenser and collected in the condensate receiver; the pump only conveys the non-condensable gases.
Vacuum and sizing
Vacuum cooking and extraction: how much vacuum is needed
What the manufacturers say about pressure, pumping speed and sizing.
Which vacuum
The manufacturers describe the benefit: less heat (Busch), low or lower temperature (Becker, Edwards). We determine the pressure required together with you, based on the product and the desired boiling temperature.
Which pump types
Busch names the liquid ring series DOLPHIN for cooking and sugar coating, plus COBRA, R5, PANDA/PUMA as well as MINK, SAMOS, SECO and TYR; Edwards the XDS scroll vacuum pump for extraction and LR for cooking and vacuum cooking; Becker the VADS; Pfeiffer Vacuum the Roots pump HiLobe; Leybold the SCREWLINE for botanical processing.
What the manufacturers point out
Busch: degassing the mass, cooking with less heat. Becker: gentle, at low temperature. Edwards: lower temperature. Elmo Rietschle names deodorisation of salad oil and fats, coffee roasting and preservation only as a list.

Frequently asked questions
Vacuum cooking and extraction: frequently asked questions
Why cook under vacuum?
Because water boils at a lower temperature under vacuum. Busch names cooking with less heat and degassing of the mass for this, Becker gentle extraction at low temperature, Edwards extraction at a lower temperature.
How does a vacuum cooking kettle work?
The heated kettle is closed and evacuated; the water in the product boils at a lower temperature, the vapours are condensed in the condenser, and the vacuum pump only conveys the non-condensable gases. Busch names DOLPHIN for this, and in its product finder also COBRA, PANDA, PUMA and R5, Pfeiffer Vacuum names HiLobe.
Which vacuum pump for vacuum cooking in the food industry?
For mixing, preparing and cooking Busch names DOLPHIN as well as COBRA, PANDA, PUMA and R5, Pfeiffer Vacuum HiLobe, and Edwards the liquid ring series LR for cooking and vacuum cooking.
Which vacuum pump for the vacuum extraction of aromas?
Becker names the VADS for the vacuum extraction of aromas, gently at low temperature. Edwards names the XDS scroll vacuum pump for extraction at a lower temperature, Leybold the SCREWLINE for botanical processing.
Which vacuum pump for panning and sugar coating?
Busch names sugar coating under vacuum for DOLPHIN, and in its product finder also MINK, SAMOS, SECO and TYR; the product data list the series DOLPHIN, SAMOS and TYR for this.
How much vacuum does vacuum cooking need?
The pressure determines the boiling temperature: the lower the pressure, the lower the temperature at which water boils ā Busch names cooking with less heat, Becker and Edwards low and lower temperatures respectively.
Oil-free or oil-lubricated for cooking and extraction?
Both are named. Liquid ring: Busch DOLPHIN, Edwards LR. Oil-lubricated: Busch R5. Dry-running: Busch COBRA, MINK, SECO, SAMOS and TYR, Becker VADS, Edwards XDS, Leybold SCREWLINE. Roots pumps with backing pump: Busch PANDA/PUMA, Pfeiffer Vacuum HiLobe.
Which vacuum pump for pasteurisation and sterilisation?
Busch names COBRA, DOLPHIN and R5; in its product finder there are COBRA products. Elmo Rietschle names food preservation without a series.
What happens to the vapours during vacuum cooking?
They are condensed in the condenser upstream of the pump and collected in the condensate receiver; only the non-condensable gases pass through the pump. Busch names degassing of the mass.
Which vacuum pump for deodorising edible oil?
Edwards names deodorisation in chemical process engineering, Elmo Rietschle the deodorisation of salad oil and fats ā both without a series.
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.
