在毛主席无产阶级革命路线指引下,在伟大的无产阶级文化大革命运动推动下,广大保粮职工以阶级斗争为纲,坚持党的基本路线,自力更生、奋发图强地开展了群众性的缺氧贮粮的科学保粮实验。粮油缺氧贮粮保管期间,粮堆内氧气的浓度变化,是衡定贮粮品质好坏的重要指标。过去测定氧气的浓度,都是采用奥氏气体分析仪进行测定。但这种方法费时费工、劳动强度较大。而且气温在10℃以下时,准确性较差。奥氏气体分析仪又是玻璃仪器,使用中易于损坏。
Guided by Chairman Mao’s proletarian revolutionary line and under the great proletarian cultural revolution movement, the majority of grain-conserving grain workers carried out mass hypoxia stored grain with the guidance of the class struggle as their key link, their basic line, their own efforts and their own efforts, The science of food preservation experiments. Oxygen storage grain cereals during storage, the concentration of oxygen in the grain piles, is to determine the quality of grain is an important indicator of quality. In the past, the concentration of oxygen was measured using an austenitic gas analyzer. However, this method is time-consuming and labor-intensive. And the temperature below 10 ℃, the accuracy is poor. Austenitic gas analyzer is a glass instrument, easy to damage in use.
