The present paper addresses the issue of postharvest handling of grain with focus on storage, when cooling is used in order to maintain the quality of the processed product and the required storage period. The paper presents the results of the control measurements at postharvest equipment, their evaluation and comparison. The measurements were performed manually by the means of the measuring device Dickey - John type GAC 2100. Results of the measurements of temperature and moisture content of grain provide basis for decisions upon possible extension of the storage period, alternatively upon further processing of grain. The paper also describes methods of maintaining the required parameters during grain storage, such as cold preservation. This section includes description and operating principle of the device Granifrigor; the recommended storage periods of different types of crops, depending on moisture content and temperature of cooling of grain. Moreover, principles of grain storage are described with respect to division according to moisture content.
