高水分粮的化学防霉,就是使用化学药剂,即防霉剂,杀死或抑制粮食上的霉菌,从而保护高水分粮免受其危害。通常,粮食经过机械和自然干燥,水分保持在与相对湿度65—70％相平衡的水分界限以下,是比较稳定安全的,很难受到微生物的侵害。但是,由于不可避免的客观自然因素或人力物力的限制,粮食往往不能及时得以干燥,导致水分过高,霉烂变质。例如,粮食收获后,恰遇连续阴雨天气,干燥机械设施缺乏,粮食不能及时干燥;因仓房条件设施差,在季节转换或昼夜变化过程中仓内外温差过大,粮堆水分发生转移,出现结霉现象使粮食水分增高;此外,在饲料加工过程中,要 Chemical mildew of high moisture food, is the use of chemical agents, fungicides to kill or inhibit the mold on the food, thereby protecting high moisture food from harm. Normally, the food is mechanically and naturally dried and the moisture is kept below the moisture limit of 65-70% of the relative humidity, which is relatively stable and safe and hardly affected by microorganisms. However, due to the unavoidable objective and natural factors or human and material limitations, food can often not be dried in time, resulting in excessive moisture and rotten mildew. For example, after the harvest of grain, there will be continuous rainy weather, lack of dry machinery and equipment, and the food can not be dried in time. Due to the poor storage facilities in barns, the temperature difference between inside and outside the warehouse is too large during the season change or diurnal change, Mold phenomenon makes grain moisture increase; In addition, in the feed processing process, want
