85 Energy Efficiency Measures
Focusing on life cycle costing

- Unterbereich: Management
- Implementierungsaufwand :
- Einsparpotential :
Energy-efficient products are usually more expensive in the first place but they reduce the energy costs in the long run. Considering the life cycle costs instead of focusing on investments only can therefore help to yield energy savings.
Use of sensor technology for energy savings
- Kategorie: Management
- Bereich: Organization
- Unterbereich: Management
- Implementierungsaufwand :
- Einsparpotential :
The use of sensors in installations and processes helps to more easily identify energy demand, malfunctions and idle times. In combination with a regular review or automated analysis, this can serve as a basis for improvements in energy efficiency.
Use of waste heat for process heating
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Meat and production of meat products
- Implementierungsaufwand :
- Einsparpotential :
In many small businesses water for cooking, brewing or cleaning meat is heated in cooking pots. A more efficient alternative is to use the waste heat from cooling systems to preheat the water instead.
Use of advanced cooking and boiling equipment
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Meat and production of meat products
- Implementierungsaufwand :
- Einsparpotential :
Boiling and cooking of meat is responsible for about one quarter of the overall power consumption of this branch of the food industry. When purchasing new equipment, efficient technologies, good thermal insulation and multifarious applications should have a priority when energy efficiency is concerned.
Use friction for smoke generation
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Fish, crustaceans and molluscs
- Implementierungsaufwand :
- Einsparpotential :
With conventional smoking methods such as burning, it is difficult to control the volume of smoke. An alternative method for generating smoke works through creating friction between wood and a rapidly turning rough roller (or pinon shaft), thereby creating smoke. With this method a better control of the smoke volume is possible and an overproduction of smoke and in turn, energy usage can be optimized.
Use of modern freezer and chillers
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Fish, crustaceans and molluscs
- Implementierungsaufwand :
- Einsparpotential :
Due to technological progress, many older freezers and chillers are outdated today from the point of energy consumption. The use of modern systems can help to reduce the energy consumption for freezing and chilling.
Cool fruits and vegetables before deep freezing
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Fruit and vegetables
- Implementierungsaufwand :
- Einsparpotential :
The common deep freezing process sees the fruits and vegetables being frozen from room temperature. A more efficient way is to cool them before with cold water that is gained from previous cooling processes. After blanching fruit and vegetables are cooled to around 4°C with water before entering the freezing process. This is achieved by bringing them into contact with cold water. Water is then removed and collected from the fruits and vegetables and reused for the next cooling process.
Check on using osmosis for concentration of fruit juice
- Kategorie: Process-specific
- Bereich: Food processing
- Unterbereich: Fruit and vegetables
- Implementierungsaufwand :
- Einsparpotential :
For concentrating liquid food products, e.g. juice, thermal methods such as evaporation are commonly used to remove water from the original liquid. This thermal process is energy-intensive. Innovative alternatives are based on osmosis. They are a less aggressive method to remove water while preserving the organoleptic properties of the products, thus also decreasing energy demand.
