Possible accumulation of benzpyrene in wheat grain during its drying by means of a heat-carrying agent (air diluted combustion products) containing this carcinogen was studied in a laboratory set-up. With benzpyrene contained in the heat-carrier in an amount of 0.12 gamma/m3 this carcinogen was amassing in the grain with all conditions and methods of drying under study. An increased benzpyrene content in the grain by comparison with the background one was noted under optimal conditions of drying in a solid layer, boiling layer and in a suspended state by as much as 23, 11 and 3 times respectively. On the basis of these and literature data a conclusion is drawn that grain may be dried in suspended state (recirculation dryers) under definite, parctically realizable conditions without accumulation of benzpyrene therein.
在实验室装置中，研究了通过含有这种致癌物的载热剂（空气稀释燃烧产物）干燥小麦籽粒时苯并芘在其中可能的积累情况。当热载体中苯并芘含量为0.12微克/立方米时，在所研究的所有干燥条件和方法下，这种致癌物都会在籽粒中积累。在固体层、沸腾层和悬浮状态下的最佳干燥条件下，籽粒中苯并芘含量相对于背景值分别增加了23倍、11倍和3倍。基于这些及文献数据得出结论：在一定的、实际可行的条件下，可在悬浮状态（循环干燥机）下干燥籽粒，而不会在其中积累苯并芘。
