| 目的 对比研究芒果果脯热泵干燥过程与传统化石能源热风干燥的成本效益，为企业生产提供科学指导。方法 在芒果果脯干燥动力学模型基础上，为芒果果脯的干燥生产过程建立生命周期成本与效益分析模型，辅以芒果热泵干燥实验数据，验证模型的正确性，并用该模型对芒果果脯热泵干燥企业的生产成本进行预测分析，比较采用热泵干燥和传统热风干燥方法的能耗、成本效益。结果 在热泵干燥条件下，不同高度层的芒果受热均匀，可以精准调控果干温度。相较于燃煤锅炉加热干燥，采用热泵干燥可以降低17.1%的生产成本，有利于减轻企业的经济负担。与传统锅炉加热干燥方法相比，采用热泵干燥方法可使生产能耗下降30.17%，二氧化碳排放量减少了32%，符合我国节能减排发展战略。结论 证明了热泵技术在芒果果脯干燥生产上的优越性。该模型方法还可用于龙眼、荔枝等同类农副产品生产中，为果脯果干生产企业的生产成本控制提供测算方法。 |

| The work aims to compare the cost benefits of heat pump drying process and traditional fossil energy hot air drying process of mango preserves, so as to provide scientific guidance for the production of enterprises. Based on the drying dynamics model of mango preserves, a life cycle cost and benefit analysis model was established for the drying process of mango preserves. The correctness of the model was verified by the experimental data of mango heat pump drying. The model was used to predict and analyze the heat pump drying plant of mango preserves, and the energy consumption and cost benefits of heat pump drying and traditional hot air drying were compared. The results indicated that under the condition of heat pump drying, mangoes with different heights were heated evenly, and the drying temperature could be precisely controlled. At the same time, compared with coal-fired boiler heating and drying, the heat pump drying could reduce the production cost by 17.1%, which was conducive to reducing the economic burden of enterprises. Compared with those of traditional boiler heating and drying method, the energy consumption of heat pump drying was reduced by 30.17%, and the carbon dioxide emission was reduced by 32%, which was in line with the development strategy of energy saving and emission reduction in China. This proves the superiority of heat pump technology in drying of mango preserves. The model method can also be applied to the production of longan, litchi and other similar agricultural and sideline products, and provide guidance for the production cost control of preserved and dried fruit production enterprises. |
