Performance Analysis of Mixed Mode Solar Dryer for Tobacco Leaves /

Abstract

It is well recognized that mishandling organic products results in a large loss. For tobacco leaves, drying is the most effective and ideal preservation method before storage in order to reduce the growth of mould and mycotoxin. The problem of two separate temperature ranges for drying makes it very challenging to dry tobacco leaves and stems. A mixed mode, active type, affordable, and environmentally friendly solar dryer is proposed in the current study work to dry tobacco leaves. The dryer consists of an exhaust fan with a regulator to create the necessary airflow in the system, a solar collector/absorber integrated with a single drying chamber divided into two halves, and solar panels. The suggested design can maintain two distinct temperature ranges for tobacco leaves in a single cabinet with almost perfect uniformity. For tobacco leaves, the drying temperatures for the leaves and stems are 333 K and 348 K, individually. The objective of the ongoing review is to look at the exhibition of a clever blended mode sun based bureau dryer for drying tobacco. Tobacco leaves and stems can be dried separately in portions that are close to the appropriate temperature range thanks to the cabinet dryer's proposed architecture. Utilizing a verified numerical model with varied operational settings, the performance is assessed. The outcomes show improved execution records and a more equivalent circulation of temperature, tension, and speed. The drying chamber can keep a temperature somewhere in the range of 298 and 344 K, and the sun powered safeguard can reach up to 330 K. It has also been examined how air admission and outlet sizes, delta speed, gulf temperature variety, examinations of the left and right sides of the sun powered bureau dryer, and the proportion of outlet to channel width influence the sun oriented bureau dryer's typical temperature. By and large, the outcomes demonstrate the way that the proposed plan setup can keep the temperature even in various pieces of the single bureau dryer, which is a decent sign for keeping the nature of the dried tobacco leaves and stems at a standard level.
