In the hot filling production of juice drinks, the ultra-high temperature instant killing technology heats the beverage to above 100℃ through steam to achieve sterilization, while the bottle chiller quickly cools the high-temperature beverage to room temperature through spray cooling. These two processes usually operate independently, resulting in energy waste and increased carbon emissions. To solve this problem, this paper proposes a comprehensive utilization method of heat energy, which recovers the heat energy released by the bottle chiller for the preheating stage of ultra-high temperature instant killing, thereby building an efficient heat energy recycling system.
In the traditional production process, ultra-high temperature instant killing technology consumes a lot of steam, while the bottle chiller consumes refrigerant and needs to be equipped with a cooling tower for heat dissipation. If the heat energy recovery of the bottle chilling link can be used for the ultra-high temperature instant killing process, it will significantly reduce energy consumption and optimize energy utilization.
The heat energy utilization system designed in this paper includes an ultra-high temperature instant killing device, a filling and capping device, a conveyor line and a bottle chilling system. The bottle chilling system consists of five temperature zones, each of which is equipped with an independent heat exchanger and water pump to achieve gradual cooling and heat energy recovery. During the production process, the beverage is first heated to 100°C, then enters the filling and capping device, and finally cools down in stages through the bottle cooling system. The water temperature of the bottle cooling machine rises rapidly during operation, and the heat energy is recovered through the heat exchanger and used to preheat the low-temperature beverage, forming a closed-loop heat energy cycle.
The system can effectively reduce the consumption of steam and refrigerant, reduce waste heat emissions, and achieve energy conservation and emission reduction goals. At the same time, the system has an automatic dynamic control function, which can adjust the refrigerant supply according to the real-time temperature to ensure the stability of the production process.
In summary, the comprehensive utilization method of heat energy studied in this paper effectively recovers the heat energy in the bottle cooling link and is used in the preheating stage of the ultra-high temperature instant killing device, which significantly improves the energy efficiency of juice beverage production and reduces carbon emissions.(The article information comes from BREW & BEVERAGE TECHNOLOGY AND EQUIPMENT)
