“…Останніми роками значно зросла зацікавленість дослідників до вивчення комбінованих процесів сушіння з використанням теплових насосів спільно з інфрачервоними випромінювачами. Так, наприклад, дослідження комбінованого конвективно-радіаційного сушіння сировини рослинного та тваринного походження поводились в Польщі [10], Таїланді [11], Китаї [12,13], Туреччині [14]. Досліджувалися випромінювачі різної потужності, які випромінюють в дальній ІЧ області спектра, в результаті було встановлено, що зі збільшенням потужності, що підводиться до ІЧнагрівачів, загальне енергоспоживання зменшується за рахунок прискорення процесу сушіння, а ІЧ сушіння сприяє створенню більш пористої структури в сушеному продукті, що дозволяє отримати продукт з меншою усадкою і поліпшеною регідратацією.…”

The promising development of convective drying of thermolabile materials is the use of heat pumps. The main advantages of heat pump drying are high energy efficiency, controlled thermal conditions of drying, high quality of the final product, environmental cleanliness of the technological process.The processes of air treatment in convective heat pumps with different schemes of dehydration of the drying agent are considered in the paper. As determined, the main disadvantage of heat pump drying is the long duration of the process due to the drying temperature limitation not exceeding 50-60 °C, and the dried material is not initially heated above the temperature of the wet thermometer, which is 25-30 °C. The possibility of using infrared radiation in combination with a heat pump was studied to intensify the process of low-temperature convective drying. It is shown that the combination of heat pump and infrared drying processes provides a synergistic effect, which leads to a shorter drying time and reduced energy consumption, as well as to obtain better quality dried products.

“…Deng et al. (2011) experimented on infrared‐assisted HPD and showed higher equilibrium moisture content as compared to simple HPD. Gungor, Erbay, and Hepbasli (2011) performed the experiment to analyze the performance of the gas engine‐driven HPD and found a drying chamber exergy efficiency of 39.26%–43.24%.…”

Novel waste heat recovery‐assisted heat pump dryer is designed, developed, and experimented in different operating modes. Energy, exergy, economic, and exergoeconomic parameters of the dryer with and without waste heat recovery are experimentally compared. Radish chips are dried to remove moisture from 93.5% to 10.5% at fixed dryer inlet air velocity. Both energy and exergy efficiencies are found highest for the waste heat recovery‐assisted (hybrid) system (56.26% and 35.9%, respectively). Specific moisture extraction rate (2.4 kg/kWh) and coefficient of performance (6.72) are highest for the hybrid system. The payback period for the hybrid system over the simple system is 33 months. The lowest exergoeconomic factor is for expansion devices in both simple and hybrid systems (0.0918 and 0.1348, respectively). Total exergy destruction costs for simple and hybrid systems are 0.10148 and 0.1266 $/h, respectively. The most important component that needs to improve based on the exergoeconomic factor is the drying chamber. Practical applications In the present study, a novel heat pump dryer assisted with waste heat recovery from the diesel engine is designed and developed. Various energy, exergy, economic, and exergoeconomic performance parameters with and without waste heat recovery are experimentally compared. To check the applicability, the radish chips have been dried to remove moisture from 93.5% to 10.5% at fixed dryer inlet air velocity. The testing shows that the proposed system is superior as compared to the simple heat pump dryer in terms of both energy and exergy efficiencies, specific moisture extraction rate, and overall heating coefficient of performance. The payback period for the proposed system over a simple one is found 3 years approximately. The proposed system can be a futuristic and promising solution for the drying applications, which satisfies two purposes: An effective way to utilize the engine waste heat and superior system performance.
