| Basil is a popular aromatic and annual herb growing in many regions of the world. Immediately after its harvesting, the highly perishable raw material, i.e. leaves, have to be preserved against deterioration and spoilage. More often, during peak period, most of the crop is lost/wasted due to lack of proper post-harvest processing techniques. Drying is by far the most widely used treatment, which needs to be performed very carefully and preciously so as to preserve the aroma and color of the leaves. Various drying treatments and experimental methods viz., solar drying, tray drying, vacuum |

| ABSTRACTThe main aims of this work are fabricate simple solar dryer for tomatoes fruits drying, solar dryer and open solar drying were used to dry tomato slices, and study of drying time influences on moisture content losses and weigh of tomatoes slices. Also, to studying various parameters such as relative humidity, temperature and velocity of air on tomatoes drying and compared to solar dryer and open solar dried during tomatoes fruits drying. Tomatoes are sliced to a thickness of about 10, 15 and 25 mm. The sliced crops are arranged in single, twice and third layers on surface of mats... |

| Drying is the most common method of medicinal plant preservation and, due to high investment and energy costs, drying is also a large expense in medicinal plant production. Drug quality and consequently earnings are significantly influenced by the drying regime. Conventionally, low drying temperatures between 30 and 50°C are recommended to protect sensitive active ingredients, but the decelerated drying process causes a low capacity of drying installations. Therefore, the objective of research in medicinal plant drying is... |

| Betel leaf or “Paan” is contemplated as “a neglected green gold of India” due to its nutritional, financial, medicinal, social and cultural values. However, surplus production of the leaves during the glut season and lack of adequate storage facilities compel the betel leaf growers to sell it at a through away price. Therefore, the current study was taken up to enhance the shelf life of the leaves by four different drying methods like shed drying, hot air oven drying, vacuum drying and freeze drying. Eight different thin layer drying models were studied... |

| Bioresource products like cassava, which are susceptible to deterioration and waste, benefit greatly from drying as a preservation technique. A prototype for drying cassava chips and other agricultural goods has been developed and tested. Heat source, suction blowers, and drying chambers make up this dryer. An air-forced drying chamber is a separate unit from a drying chamber. Air-forced chamber uses ambient air to dry, while drying chamber uses heat from biomass furnace. Fresh cassava root was peeled, rinsed, and chopped using a... |

| Mallow leaves (Malva sylvestris L.) with initial moisture of 5.02±0.003 on dry basis (82.5% on wet basis) were dried using three different drying methods, microwave, convective and vacuum. The leaves that weigh 75 g each were dried until their moisture fell down to 0.10±0.005 on dry basis (approximately 9% on wet basis). The following drying levels were used in each of the drying processes: 6.67, 8.67, 10, 11.33 W g-1 microwave power density; 50, 75, 100 and 125 °C for convective drying; and 3, 7 kPa at 50 and 75 °C for vacuum drying. Drying periods ranged... |

| ABSTRACT This study investigated the effect of a drying method with intermittent ratios on the effective drying time, specific energy consumption and essential oil yield of clove basil (Ocimum gratissimum L.) leaves. The drying tests were conducted at the Postharvest Laboratory of Medicinal, Aromatic and Condiment Plants, from the Departamento de Engenharia Agrícola of the Universidade Federal de Viçosa, Viçosa, MG, Brazil (20° 46’ 13.5” S; 42° 52’ 23.3” W, and altitude of 645 m) in October and November 2017. The experiment was conducted by using a 3 × 4 factorial scheme including three drying temperatures at 50, 60 and 70... |

| ABSTRACT The objective of this research was to evaluate the effects of different drying methods on physiological quality of crambe seeds. Crambe seeds of FMS Brilhante cultivar were produced in the Lageado experimental farm (UNESP, Botucatu, Brazil) in 2012. The drying methods were: artificial drying with hot air, artificial drying with fresh air, natural yard drying, natural shade drying and natural field drying. The water content of seeds was monitored before, during and after drying.... |

| Opuntia ficus-indica, also known as nopal, is a cactus which grows on arid and semiarid lands of America. Dehydrated nopal is an alternative for food preservation, but drying times of cladodes are very long. The objective of this study was to evaluate dry kinetics of nopal thin slices, of 4 mm thick, 140 mm long and 17 mm wide. We conducted the drying process in a convective cross flow tray dryer at 35 °C, 45 °C and 60 °C and air velocities of 1 m s-1, 1.5 m s-1 and 2 m s-1, under laboratory conditions. Results indicated that the effect of air temperature on the drying time of nopal slices was higher than the air velocity (p≤0.05). The |
