85 Energy Efficiency Measures
Heat recovery for fermentation
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Bakery and farinaceous products
- Implementierungsaufwand :
- Einsparpotential :
Fermentation takes place at temperature levels up to 40 °C. Instead of using conventional heating methods such temperatures can easily obtained by using waste heat from other systems such as ovens, refrigeration systems or compressors. This will help to reduce energy consumption.
Use of ultrasonic evaporators in evaporation
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Bakery and farinaceous products
- Implementierungsaufwand :
- Einsparpotential :
For humidification in fermentation chambers, ultrasonic evaporators can be used instead of electrically heated evaporators. This can help to considerably reduce power for evaporation. In addition, ultrasonic evaporators have the double advantage to prevent condensation and also product surface drying as their mist contains very small droplets.
Turning off bakery equipment
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Bakery and farinaceous products
- Implementierungsaufwand :
- Einsparpotential :
Switching bakery machinery and oven off during idle time and in between baking processes leads to a reduced energy consumption.
Energy-optimized choice and use of baking ovens
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Bakery and farinaceous products
- Implementierungsaufwand :
- Einsparpotential :
Baking ovens are one of the main power consumers in the baking industry. Various approaches such as choosing an oven with an optimal "surface-to-baking surface" , a regular control of steam injectors, a minimisation of idle times and a constant use of the maximum load are important for reducing energy consumption in bakeries.
Hot water network instead of local electric heating
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Bakery and farinaceous products
- Implementierungsaufwand :
- Einsparpotential :
The hot water network is usually heated with natural gas or heating oil boilers. Connecting the dishwasher to the hot water network will result in lower electricity costs and environmental pollution than compared to using the integrated electric water heater. The integrated water heater then only has to bridge the temperature gap due to e.g. thermal losses.
