Training Course on Energy Management in Dairy Industries in Mongolia

Ulaanbaatar, Mongolia, in September 2002

By request from the Government of Mongolia, experts from UNESCAP and the Morinaga Milk Industries Company, Japan, conducted an energy audit and a training course on energy management to identify potential for energy savings and productivity improvement.

The dairy industry in Mongolia is very important for local supply of a nutritious, varied and affordable diet. Industries expressed interest in reducing energy costs for production and increasing product quality as well as reducing environmental impacts. The purpose of the training was to enhance productivity in dairy industry through energy conservation and efficiency improvement and modern dairy production technology. Training was provided on the following subjects:

• Principles of energy management
• Environmental policy and internal audit
• Good manufacturing practice
• Milk products standards
• Operational management and quality control
• Energy saving measures

Based on the on-site assessment, the advisory team made the following observations and recommendations on energy saving potentials:

1. Process improvement

• Prevent leakages
• Remove of unnecessary equipments and pipes
• Optimize pressure of homogenization
• Control overrun in ice cream mix
• Manage cold storage

2. Equipment improvement

• Reuse water
• Reuse steam drainage
• Strengthen heat insulation of pipes
• Replace the homogenizer motor
• Improve the power factor

3. Additional measures

• Heat Recovery of the Dryer
• Integration of the Voltage Transformers
• Adoption of Distributed Heat and Power Generator

Large potential exists for energy savings and cost reductions in the factory. Savings amount to 15.5% for water consumption, 12.8% for heat consumption, and 21.5% for electric power consumption, respectively. If these savings are realized, total annual energy expenses could be cut by 14%.
