Exhaust air purification on the frying line – for bacon strip production

Neutralize odours, avoid grease residues and save energy with oxytec Clean Fryer Air

In the industrial production of bacon strips, the frying process produces considerable quantities of greasy, odorous and thermally contaminated exhaust air. This contains fatty acids, smoke components, organic vapors and aerosols, which not only cause odor problems, but can also lead to deposits, fire loads and technical faults.

With the oxytec Clean Fryer Air System we offer a powerful solution for exhaust air cleaning directly at the frying line – contact-free, residue-free and without thermal post-combustion (TNV). At the same time, the hot exhaust air can be used for heat recovery and process heating – for example with heating systems from our subsidiary Condoheat.

Typical emissions from frying lines for bacon production

Emission source Typical pollutants Special features
Frying section Fatty acids, smoke, VOCs, vapors, odor molecules High temperatures, high humidity, intense odors
Drip areas / deflectors Oil mist, aerosols, particles Sticky, heat-resistant deposits
Cooling zones / extractor hoods Residual heat, steam, light smoke components Often diffuse emission, difficult to detect

Why exhaust air purification is necessary for bacon frying lines

  • Grease and smoke components can be deposited in ventilation and roofs
  • Odors are extremely diffuse and prone to complaints
  • Sticky aerosols and VOCs pollute filters and heat exchangers
  • Thermal post-combustion (TNV) is energy-intensive, requires a lot of maintenance and is difficult to approve
  • In the absence of exhaust air purification, there is a risk of production downtime, conditions or loss of approval

Legal requirements

  • TA Luft (2021): Compliance with VOC limit values and organic emissions
  • GIRL (Odor Immission Directive): relevant in proximity to residential areas
  • BImSchG / 31st BImSchV: Requires approval from certain production quantities
  • Hygiene and fire protection requirements in fat-processing plants

oxytec supplies with all necessary measurement certificates, planning documents and official protocols.

FAQ – häufige Fragen

What emissions are produced during bacon strip production?

Frying bacon strips typically produces:

  • Fatty acids and smoke components
  • VOC-containing vapors and aerosols
  • Intense odors
  • Humid and hot exhaust air

These emissions are sticky, odorous and have a strong filter effect, which means they can be deposited in hoods, pipes and heat exchangers.

How does the oxytec Clean Fryer Air technology work?

UV-C radiation breaks down organic molecules in the exhaust air

The resulting oxidation products are further decomposed by ozone reaction

Result: smoke, grease and odours are neutralized without leaving any residue

The process works dry, without open flames, without chemicals

Can Clean Fryer Air replace thermal oxidation (TNV)?

Yes – completely. Advantages over TNV:

  • No gas consumption, no flame, no secondary exhaust gases
  • Significantly lower energy consumption (up to 60 % savings)
  • Less maintenance required, no heat-up times
  • Fewer approval hurdles and CO ₂ balances

How high is the odor reduction with Clean Fryer Air?

Experience shows:

  • > 90 % reduction of odorous substances (also bacon and smoke odor)
  • Significant reduction in VOC pollution
  • Verifiable through olfactometric measurements (in accordance with EN 13725) and TA-Luft-compliant sampling

Can the system be integrated into existing systems?

Yes – Clean Fryer Air is:

  • modular in design
  • can be integrated into existing hoods, ducts or technical rooms
  • also available as plug & play module for retrofitting
  • Can be combined with heat recovery via Condoheat

How maintenance-intensive is the system?

Low maintenance:

  • UV-C lamps: approx. 8,000-10,000 operating hours
  • No filter clogging, due to dry oxidation
  • Cleaning of the ozone chamber every 6-12 weeks depending on operation
  • Optional with maintenance contract, remote monitoring and replacement service

Is the system subject to approval?

The systems are:

  • generally permit-free when replacing existing systems
  • Compliant with TA Luft, GIRL and BImSchG
  • verifiable with measurement protocols and emission certificates
  • We provide support with communication with authorities and approval procedures

Can the waste heat from the exhaust air be used?

Yes – with heat recovery systems from Condoheat:

  • Air-to-water or air-to-air heat exchanger can be integrated
  • Use for heating, cleaning or process heat
  • Particularly efficient with continuous 3-shift operation

Is the system safe for exhaust air contaminated with grease and smoke?

Yes – oxytec systems are:

  • specially developed for greasy, hot and smoky air flows
  • explosion-proof according to ATEX-compliant design, if required
  • equipped with temperature monitoring and fire protection technology (optional)
