Most important feature of the storage systems is to preserve the integrity of the grain for a given period with minimal loss in quality and quantity. The main objective of this study aimed to choose the proper conditions which ensure safe storage process using infrared heating at the optimum radiation intensity of 882.67 W/m² and exposure time of 15 min and the ultraviolet radiation at radiation intensity of 3.538 mW/cm² and exposure time of 40 min on storability of cowpea seeds using different types of plastic hermetic bags in comparison with polypropylene (pp) woven bags. The changes in cowpea seeds quality during storage of pre-treated cowpea seeds in terms of moisture content, protein content, total microbial count and insect detection were also determined. The results show that, the moisture content of seeds stored in pp woven bags increased in contrast with both types of studied hermetic bags, oxygen concentration for hermetic bags decreased during storage period and carbon dioxide increased unlike pp woven bag, The rate of seeds infection with microorganisms and weevils was lower comparing with the samples stored in both types of hermetic bags and crude protein content of seeds stored in hermetic bags reduced at a very slight rate in comparison with that stored in woven bag.

Experiments were carried out through summer season of 2013 in the rice mechanization center at Meet El-Dyba, Kafr El-Sheik Governorate, Egypt for trying to obtain high quality of dried peppermint with the highest volatile oil percent at least drying time. The experiments were conducted under the following variables of two different drying methods (sun drying and solar greenhouse dryer), two different plant conditions (whole plants and leaves), three different loads (2,4 and 6 kg/m2) and three different air velocities (0.5, 1 and 1.5 m/sec.) under continuously fan operating system. The moisture content, relative humidity, temperature, volatile oil and total microbes count (TMC) were in the proper best region under the following conditions: Use of solar tunnel greenhouse for drying peppermint. Drying the peppermint as leaves in order to reduce the drying time. Procedure the drying process at air velocity of 1m/s. Loading the greenhouse by about 4 kg/m2. [ABSTRACT FROM AUTHOR]
