Innovative meat processors resort to innovative air filtration procedures for their smoking processes

The amount of harmful emissions that companies are allowed to release are strictly regulated by national legislations. Investments in environmentally-friendly equipment and procedures will not only help reduce those emissions, but will also help reduce cooperating costs – thus leading to competitive success for the company. Choosing a suitable filter is important. Using a filter that is made out of durable material will minimize maintenance and repair times, as well as completely eliminate replacement costs!

Meat processing praxis and its alternative

Emissions from industrial frying lines and smokehouses consist of a greasy, oily and tar-like compound, which has a very strong odour. Therefore, technical requirements related to air purification are very high. Traditional solids separators are often not an optimal solution because if the filter is not of a suitable material, the tar and oil can quickly cause blockages – making it useless after a short period of time. Due to this, some smokehouse and frying line operators still work with conventional thermal after burning systems.

In these systems, the polluted air is converted to water and carbon dioxide via deep warming effects, and is thus cleaned. However, this process has several disadvantages. Firstly, it is very environmentally damaging due to the fact that the required temperature (about 750°C) can only be obtained by expending large amounts of combustible energy (e.g. gas or oil), therefore leading to enormous CO2 emissions. This also means huge operating costs for the smokehouse and frying line operator due to the consumption of limited reserves and rising prices for traditional resources.

Fortunately, there are energy-efficient alternatives on the market. The energy-efficient exhaust air cleaning method is based on a system that is a combination of an electrostatic precipitator and a scrubber. First, the flue gas is led to the tubular electric filter. Next, particles and droplets are electrostatic-ally charged, and then filtered out through the exhaust. Due to the electric field, the tar-water mixture deposits on the filter wall and then runs down into a collection barrel. The particle filtration is followed by the gas scrubbing. First, the flow of air is led into the gas scrubber. Then, the gaseous component of the exhaust air is bound and removed by the absorbent (washing liquid). Lastly, the completely purified gas leaves the air filtration system up through the chimney. Compared to conventional post-combustion systems, this innovative air-purification system uses over 80% less energy!

The modern exhaust air system is not only energy efficient, but also contains a highly economical and durable filter. The electrostatic precipitator enables sustainable purification of the exhaust air without filter replacement. The filter does need to be cleaned habitually in order to avoid permanent deposits, but this is carried out at regular intervals automatically. The electrostatic precipitator has a heater that heats the electrostatic filter once a week and removes viscous tar from the filter.

Also, because the emission control system is connected to the smoke generator, the exhaust air filter system starts up as soon as smoke is produced. Because of this, it can be ensured that the food processing equipment is constantly remaining environmentally-friendly whenever the energy-efficient air purification system is in use.

Energy-efficient air pollution control

The importance of clean air is increasingly being recognized globally. The industrial nations in particular hold a large responsibility in keeping the air free of pollution, therefore it is essential for companies to invest in innovative systems for air pollution control.

It is also important that environmental-friendly systems help instead of hurt companies economically. By using innovative exhaust filter systems, food processing companies that use smokehouses and industrial frying lines can sustainably prevent pollution caused by smoke and odours, while simultaneously minimizing energy consumption – an important contribution to climate protection.

KMA Umwelttechnik GmbH
