Objective:
We conducted a survey at one of the leading beverage manufacturers in Thailand. The survey’s primary objective was to find gaps in the steam system at the plant.
Issues:
During our survey, we observed that the plant was facing difficulties in maintaining a stable temperature at the bottle washer. Our observations revealed an overshoot of 3 to 5oC in the process temperature. The fluctuations in temperature not only affected plant operations but also resulted in excessive steam consumption. Therefore, during our discussions with the plant, we prioritized addressing the issues pertaining to the bottlewasher.
We found that the existing mechanical temperature control valve was not able to consistently maintain the required process temperature.
Solution:
Our field engineer studied the bottle washer in detail to establish its specific process requirements. Based on this analysis, a suitable temperature control valve was selected to maintain the desired temperatures in each zone. The solution focused on minimizing energy consumption in the bottle washer while sustaining optimum productivity (bottles per minute).
Our engineer collaborated with the plant team to successfully implement the solution, and the benefits of the implementation were documented by the plant team.
Benefits:
a. Consistent process temperature.
b. Reduction in steam consumption resulting in fuel savings of 2%.
c. Water savings of 71 tons per annum.
d. 5.7 ton reduction in CO₂ emissions.
e. Monetary savings of 90,606 THB per annum.
