我国南方谷物收获季节,特别夏收水稻和春收小麦期间高温多雨、空气相对湿度大,为适应生产队抢收并烘干受湿谷物而设计的堆放式简易谷物烘干机(已在本刊一九七五年第一期上介绍)。据调查了解,有些使用单位,由于操作规程未能完全掌握,如取用过高的热风温度,使烘干后谷物质量有所下降。现将该机的使用说明及注意事项介绍如下,供参考。一、燃烧炉及堆放架用料 1. 燃烧炉煤炉约用红砖100块,大方砖3块、柴炉约用红砖130块,大方砖4块,炉高11块。 2.堆放架堆放架的前后两挡墙,约用300块红砖。另外,两个梯形木架(用40×40毫米方木)。长3760毫米,直径40～50毫米圓竹16根。长4000毫米,宽30～40毫米的竹片16条。铁筛网(10～14目) In the south of China cereal harvest season, in particular, the summer harvest of rice and spring wheat harvest during the high temperature and rain, the relative humidity of the air, in order to meet the production team grab and dry wet cereal designed by the stack type simple grain dryer Introduced in the first period in 1975). According to the investigation, some units were used. As the operating procedures were not completely mastered, such as the hot air temperature taken too high, the quality of cereals after drying decreased. Now the machine’s instructions and precautions described below, for reference. First, the combustion furnace and stacking materials 1 burning furnace about red brick 100, 3 large brick, wood stove about 130 red brick, 4 large tiles, 11 high furnace. 2. Stacking racks before and after the two retaining walls, about 300 red brick. In addition, two trapezoidal wooden racks (40 x 40 mm square wood). 3760 mm long, diameter of 40 to 50 mm bamboo 16. 4000 mm long, 30 to 40 mm wide bamboo 16. Iron mesh (10 ~ 14 mesh)
