为完成我市逐年增加的粮食干燥任务,满足城市粮食供应和出口创汇需要,从1982年起在大连市开发了一种JHZ型粮食干燥机。这种新型粮食干燥机,是一种间接加热式干燥机。它具有热耗低,烘后粮品质好,可以使用低值煤作燃料,主机实现了工厂化生产等特点。适于在我国大规模发展。从数量上看,这种干燥机在我市已建成投产七台,正在建设中两台,到年底,我市将有九台投入使用,日干燥玉米能力将达到3,000吨。从性能上看,已发展了JHZ-33型,JHZ-47型和JHZ-49型三代。在这些干燥机的研制和建设中,都把降低消耗、节省能源作为主要目标,特别是JHZ-49型干燥机节能效果显著。根据“粮食干燥技术”一书介绍,我国间 In order to complete the increasing grain drying task of our city year by year and meet the needs of urban grain supply and foreign exchange earning, a JHZ grain dryer has been developed in Dalian since 1982. This new grain dryer is an indirect heated dryer. It has low heat consumption, good quality baked goods, you can use low-value coal as a fuel, the host achieved the characteristics of factory production. Suitable for large-scale development in our country. In terms of quantity, this dryer has been put into operation in our city, with seven units under construction and two units under construction. By the end of the year, nine units will be put into use in the city and the daily dry corn capacity will reach 3,000 tons. From the performance point of view, has developed the JHZ-33 type, JHZ-47 type and JHZ-49 type three generations. In the development and construction of these dryers, all reduce the consumption and save energy as the main objective, especially the JHZ-49 dryer energy-saving effect is remarkable. According to “Food Drying Technology,” a book introduced between our country
