FOR CLEAN FUTURE!

The demands for contemporary production are becoming continuously more stringent. The focus is increasingly shifting onto environmental and energy aspects – many of these measures are not only advantageous for the environment but also for producers.

Suitable smoke cleaning technology is used according to the regulations applicable on site and the smoke generator used.

For clean future!

Smoke cleaning by a condenser:

For chambers with a steam-smoke generator the waste-gas steam-smoke mixture can be washed by a condenser. The exhaust gas is passed through a water curtain generated by spray jets, which washes out the smoke constituents from the steam-smoke mixture. In this way any odour pollution into the environment can be completely avoided without the use of chemicals. The remaining gaseous component of total C is only a fraction – which also means significantly less impact on the environment.

Exhaust smoke cleaning by a thermal – catalytic after-burner:

The thermal – catalytic after-burner cleans the smoke by combustion. The cata- lytic converter supports and accelerates the chemical reaction. Due to the high-quality catalytic converter, coated with a precious metal alloy, temperatures of approx. 450°C are sufficient to clean the exhausted smoke. In addition, the reaction in the catalytic converter produces heat, which in turn reduces the energy required for heating.

Exhaust smoke cleaning by thermal after-burner:

The thermal after-burner is heated by means of an oil and gas-fired burner to approx. 700°C, in order to clean the waste air.

Several units can be connected to one thermal after-burner.

PFE Prepare – Fresh – Exhaust – System

Use: All AUTOTHERM universal and steam-smoke chambers use the outgoing heat from your chambers for energy saving during drying

We developed the Prepare – Fresh – Exhaust (PFE) system to optimise the energy efficiency of the AUTOTHERM universal and steam-smoke units. Drying products, in particular, is very energy intensive!

The energy present in the outgoing air is used by means of a heat exchanger, in order to preheat the drawn in fresh air. The preheated fresh air saves heating energy and can accelerate drying.

The P-F-E system reduces the energy required for drying by up to 20 %.

The AUTOTHERM P-F-E system can be retrofitted to almost all AUTOTHERM universal and steam-smoke chambers.

CES Clima – Energy – Saving – System

Use: All AUTOTHERM cold-smoking chambers and controlled climate storage rooms use the ambient air to reduce energy costs

With the AUTOTHERM C-E-S system it is possible to specifically use the drawn in fresh air in order to save the energy used to heat, cool, humidify and dehumidify.

To this end, the fresh air to be drawn in is measured outside the unit by means of sensors. A microprocessor compares these parameters with the values inside the unit with regard to temperature and relative humidity.
Only if the fresh air is suitable for positively affecting the required parameters in the chamber does the flap open and fresh air is drawn in.

If this air is not suitable, because it is too moist or too dry, too cold or too hot, no fresh air is drawn in and the required parameters are established by switching on heating, cooling and/or humidification.
This prevents, e.g. too cold or too moist air from getting into the air conditioning system which then, in addition to the air inside the unit, has to be conditioned to the required parameters with a high energy cost.

AEC Air – Efficiency – Control – System

Use: All AUTOTHERM cold-smoking chambers and controlled climate storage rooms use state of the art control and process technology to optimise energy use

The A-E-C system optimises the drying process and prevents drying errors such as drying rings or the formation of mould.

Air circulation plays a decisive role during drying in the controlled climate storage or curing chambers and during cold smoking.
The circulating air is primarily responsible for ensuring that the product in the whole chamber dries uniformly.

The A-E-C system takes these factors into account and controls the circulating air velocity depending on the actual value – setpoint ratio of the relative humidity in the chamber. As a result more intensive drying is achieved when necessary and less intensive drying when possible.

This enables optimised drying, which in turn enables the products to be produced effectively and without drying errors (neither mould nor drying rings).
This not only optimises drying but also saves energy.

On customer wishes, thermal – catalytic after-burners and thermal after-burners can be equipped with heat recovery systems.  These produce hot water or are used to preheat the waste air to be cleaned.
