Solar thermal dryers are solar-operated gadgets utilized to dehumidify various products, especially food items and rubber sheets. This article provides detailed design, parametric studies, and an in-depth review of mixed-mode solar dryers (MMSD) with a case study of fish drying near coastal lines. Due to several advantages compared to open sun drying and prominent performance index compared to indirect and direct type solar dryers, mixed-mode solar dryers have large adaptability on the field. Moreover, mixed-mode solar thermal dryers with different augmentations are reviewed, for instance, mixed-mode solar dryers with evacuated tube collectors, phase change materials, ultraviolet rays stabilized housing, and dehumidifiers. The case study of fish drying near the coastal line of Gujarat, India has been carried out to study the present scenario of the drying activities. Hence, the objective of this review is to identify the capable mixed-mode solar dryer with heat recovery systems. Substantial reviews within the article suggest an essential need to implement the hybrid mixed-mode solar dryer cum distiller technology for small-scale enterprises that can simultaneously provide potable water near coastal lines along with drying of fishes from the solar dryer. Furthermore, future research demands such hybrid mixed-mode solar drying systems that strongly fulfill the requirements of local communities near coastal lines involved in fish drying activities.
太阳能干燥器是一种太阳能驱动的设备，用于除湿各种产品，特别是食品和橡胶片。本文详细介绍了混合模式太阳能干燥器（MMSD）的设计、参数研究和深入评价，并以沿海地区的鱼类干燥为例进行了案例研究。与开放式太阳干燥相比，混合模式太阳能干燥器具有许多优势，与间接和直接式太阳能干燥器相比，其性能指标更为突出，因此在该领域具有很大的适应性。此外，还对不同增强型混合模式太阳能热干燥器进行了回顾，例如，带有真空管集热器、相变材料、紫外线稳定外壳和除湿器的混合模式太阳能干燥器。在印度古吉拉特邦沿海地区进行了鱼类干燥的案例研究，以研究干燥活动的现状。因此，本综述的目的是确定具有热回收系统的高效混合模式太阳能干燥器。本文中的大量综述表明，对于沿海地区的小型企业来说，迫切需要实施混合式混合模式太阳能干燥器和蒸馏器技术，以便在提供饮用水的同时，从太阳能干燥器中干燥鱼类。此外，未来的研究需要这种混合式混合模式太阳能干燥系统，它能够满足沿海地区参与鱼类干燥活动的当地社区的需求。
