For taking away the humidity material drying procedure is achieved. Evolution of roof variety, particularly, solar cycle drier kayak drier solar tunnel drier, and greenhouse sprays length research workers have learned greenhouse drier. Inside this newspaper drier below convection variety and convection sort have been all studied. Greenhouse drier provides rather large excellent product compared to sun drying that is open plus the harvest declines are reduced by it. It's been discovered that the use of rainwater drier below convection lessens moisture material in addition to drying speed is rapid and comparative humidity is significantly less than convection manner.

Exergy Analyses

This paper presents energy and exergy analyses of solar drying of coconuts in a hemispherical solar tunnel drier. Coconuts were dried from an initial moisture content of about 55% (w.b.) to 7% (w.b.) in the solar tunnel drier in 60 hrs whereas the open sun drying process takes 153 hrs for reducing the moisture content to the same level. The drying experiments were conducted at a mass flow rate of 7.25 kg/s with an average air velocity of 0.1 m/s. Using the first law of thermodynamics, energy analysis was carried out to estimate the amount of energy received by the solar tunnel drier and the ratios of energy utilization. However, exergy analysis was accomplished to determine the exergy loss and exergy efficiency by applying the second law of thermodynamics. Energy utilization, energy utilization ratio, exergy inflow and exergy loss in the drier were studied and these values are found to be increased with increasing solar radiation. The exergy inflow and exergy loss in the drier varied between 0.194 kJ/s–8.18 kJ/s and 0.085 kJ/s–5.377 kJ/s respectively. The exergy efficiency of the drier varied between 23.6%–53%.

And Performance

This paper presents dying efficiency and performance of the solar tunnel dryer for drying of garlic. The dryer is a tunnel like semi-cylindrical in shape, poly house made up of UV-stabilized polyethylene sheet. The capacity is large enough that it can be used to dry 400 kg of garlic under controlled environmental conditions. The temperature inside the dryer was always higher than the ambient and the variation varied from 8-30 ºC. Initial moisture content of garlic was reduced from 66 % (w.b.) to about 9 % (w.b.) in 9 days which is considered to be a safe level. During the drying process the average thermal efficiency of the drier was estimated to be about 13.45 %. Drying time was considerably reduced with the use of a solar tunnel drier and pressing of the sample. Also, the final dried garlic was found to be good in terms of quality and sensory evaluation shows that it is highly acceptable.

Canning Industry

In an attempt to develop a suitable substitute for the agar used in large quantities by the canning industry, gelose preparations were made from bleached and unbleached Irish moss. About 30 to 60% of the total moss solids, depending on the type of moss used, were extracted in one-half hour by hot water. Suspended solids were removed by filtration with diatomaceous earth, and the extracts purified with activated charcoal. Extracts were dried successfully on a laboratory model double-drum drier, an experimental spray drier, an experimental tunnel drier, and by air-drying the concentrated extract at room temperature. All methods of drying yielded products capable of forming good jellies.Although agar jellies were definitely stronger than those from equivalent concentrations of Irish moss, the addition of 0.2% potassium chloride produced jellies from Irish moss that were stronger than those from agar. On the basis of consumer taste panel tests on canned chicken, no statistically significant difference could be demonstrated between the acceptability of agar and Irish moss jellies.
