对高大平房仓的门窗、通风口、环流熏蒸管道等易导热部位用PVC发泡塑料作隔热保温处理,以提高仓房的隔热性能,进一步改善仓房的储粮条件;地坪用糠壳铺垫,防止底层结露;秋冬季进行自然通风和机械通风降温;春季对粮面进行薄膜密闭、泡沫板压盖保冷;在膜下铺设环流熏蒸回流管网,并均匀预留若干个风口,可进行膜下环流熏蒸和全仓不揭膜通风,还可利用环流风机平衡堆内粮温;高温季节,在环流熏蒸管道上串接小功率制冷机组对粮堆进行辅助制冷,使粮堆长期保持在低温状态;夜间合理利用轴流风机适时排除仓内空间积热,降低仓温,延缓粮温上升。实践证明,粮食在储藏过程中综合运用这些储粮技术,减少了外界环境因素对粮堆的影响,可达到明显的控温效果,使高大平房仓储粮度夏时,平均粮温控制在15℃,表层最高粮温不超过23℃,确保了粮食储存安全,延缓了粮食品质陈化,降低了保管费用,取得了良好的综合效益。
On the large windows and doors warehouse bungalow, vents, circulating fumigation and other easy to heat conductive parts of PVC foam plastic insulation for thermal insulation treatment to improve the storage of thermal insulation properties to further improve the barns grain storage conditions; , To prevent the bottom of condensation; autumn and winter for natural ventilation and mechanical ventilation cooling; spring food film surface sealing, foam board gland cooler; laying under the membrane circulating fumigation return pipe network, and even reserve a number of tuyeres, can be carried out Membrane circulation fumigation and the whole warehouse is not exposed membrane ventilation, but also the use of circulating fan balance reactor grain temperature; high season, circulating fumigation pipeline in series with low-power refrigeration unit on the food pile auxiliary cooling, so that the long-term Low temperature state; the rational use of axial flow fan at night to exclude the accumulation of space within the warehouse heat, reduce warehouse temperature, delay food temperature rise. Practice has proved that the integrated use of grain storage technology in grain storage technology, reducing the impact of external environmental factors on the grain heap, can achieve significant temperature control effect, so that when the large bungalow warehouse grain summer, the average grain temperature control at 15 ℃ , The surface maximum grain temperature does not exceed 23 ℃, to ensure the safety of grain storage, delay the aging of food quality and reduce storage costs, and achieved good comprehensive benefits.
