| Popis: | The result of improving the pasteurizer is a 6-fold decrease in the specific metal consumption by the device, in comparison with the basic design (26kg/m2versus 160kg/m2). The duration of heating and pasteurization of drinking milk at a temperature of 73...77°C while aging over 15...20s is 27.5s, which is 1.8times less. A reduction in the heat consumption for heating the apparatus is achieved, which is 1,372.8kJ (CPiPPU – Continuous "pipe in pipe" pasteurization unit), in comparison to the consumption by the basic pasteurizer, 8,448kJ. The uniformity of flow heating was established when its speed changes from 0.03 to 0.40m/s for various heat supply techniques; under the condition υ=0.4m/s, a temperature drop is ensured: at internal heating ‒ 1.4°C; in the basic design with external heating by a hot heat carrier ‒ 2.7°C; and in the proposed CPiPPU with double-sided heating ‒ 0.5°C. The comparison of heat supply techniques confirms the heat exchange efficiency of raw material processing by CPiPPU while ensuring a minimum temperature drop. The improved continuous pipe-in-pipe pasteurization unit based on the double-sided heating by a flexible film resistive electric heater of the radiating type (FFREHRT) is resource-efficient and can be used to heat food raw materials in the temperature range 15...110°C |
