Milk Pasteurizer

2. This study aims to show that a simplified surface
fitting model used for determining the energy
consumption during pasteurizing milk by
Pasteurizer in a dairy plant.
The study reveals that milk volume and the
temperature gradient between the room and the
final milk temperature can effectively be used for
predicting the energy consumption within 95%.
The objective of this study is to provide resources and methods to reduce energy
use and energy related costs in dairy processing facilities.

Objective

3. Design
The instruments used in the system:
1. Landis and Gyr E650 power meter
2. TMC6-HE temperature sensors
3. HOBO UX120-006M 4-channel analog data logger
Landis and Gyr E650 power meter TMC6-HE temperature sensors
HOBO UX120-006M
4-channel analog data logger

4. The room temperature of the plant where the
Pasteurizer is placed was measured using a
TMC6-HE temperature sensor, connected to a
Hobo UX120-006M four-channel analog data
logger which was configured to log at one-
minute intervals.
The electrical energy consumed by the
Pasteurizer was measured using a Landis and
Gyr E650 meter while the volume of milk was
extracted from the records of the plant.
Methodology

5. Findings
The results showed that the developed model is
able to figure out the electrical energy
consumption of the Pasteurizer within an
acceptable accuracy since 80% of the variation
in the electrical energy consumption by the
Pasteurizer was explained by the mathematical
model. Also, milk volume and the temperature
gradient between the room and the final milk
temperature in the Pasteurizer are primary and
secondary contributors, respectively, to
electrical energy consumption by the
Pasteurizer.
Based on the system that has been
monitored the findings reveal that the
Pasteurizer was operating within the
expected efficiency level as assumed by
the optimized electrical energy
consumption (EEC) closely mirroring the
modelled EEC with a determination
coefficient of 0.95.

6. Limitations
Implications
Originality
Only one system was monitored in this case
study. The milk blending temperatures, effects
of the insulation of the Pasteurizer, were not
taken into account in this study.
The developed model is simple to use, cost
effective and can be applied in real-time on the
dairy farm which will enable the farmer to
quickly identify an increase in the heating
energy per unit of milk heated.
The developed easy-to-use model can be used in dairy plants on similar
Pasteurizer; hence, they can devise ways to manage their energy consumption
in the plant during the heating of milk and foster some energy efficiency
initiatives.
The implementation of the developed model can be useful to dairy plants.
The maintenance of the Pasteurizer can be determined and scheduled
accordingly through energy optimization.
