Development of Ultra-high Pressure Cooling and Quick Freezing Device Based on Hydraulic Transmission

Abstract

Based on the theory of high pressure supercooling and pressure relief quick freezing, the ultra-high pressure instantaneous freezing device is developed. This device can break through the limitations of existing ultra-high pressure device design. Through the new hydraulic transmission design, It can complete fast pressurization, fast pressure relief and achieve continuous work. The matching of whole systems under certain load conditions, hydraulic transmission system, refrigeration system, pressure vessel and pressure relief system has been completed. The device can realize the whole process of ultra-high pressure quick freezing from food feeding, pressure cooling, pressure relief instant freezing and semi-automatic food discharging. Compared with the conventional same-capacity quick-freezing device, the energy consumption of the instantaneous freezing device under the design condition is only 24.52% of that of the traditional quick-freezing device, which greatly saves energy consumption. From the perspective of application, the design concept of ultra-high pressure quick-freezing device is perfected and the practical process of ultra-high pressure quick-freezing is advanced.
