背景技术 Background technique
由于国内猪饲料以玉米--豆粕型饲料为主，因此大量的玉米被应用于饲料生产中。玉米的储藏尤为重要，储存环境的高水分、高温度等很容易造成玉米在筒仓中发生霉变，影响玉米品质，霉变的玉米制成的饲料饲喂动物严重时会造成动物的死亡。 Since the domestic pig feed is mainly corn-soybean meal type feed, a large amount of corn is used in feed production. The storage of corn is particularly important. The high moisture and high temperature in the storage environment can easily cause the corn to go moldy in the silo, affecting the quality of the corn. If the feed made of moldy corn is fed to animals, it will cause the death of the animal.
人工晾晒费工费时，还受环境因素的影响，机械化的烘干设备在饲料厂的运用广泛，但现有的烘干机采用的供热原料为柴油、煤炭等，烘干过程中会造成环境污染，并且烘干成本很高。现有的烘干机多为立式、卧式固定筒烘干机，这样会造成玉米受热不均匀，烘干效率不高，造成局部烘干过度，玉米发黑，也会造成局部玉米烘干除湿程度不够，造成玉米霉变。现有的烘干机大多不设有除尘设备，这样会造成空气污染，特别是玉米皮，不经过收集处理会到处飞扬，造成整个厂区的污染，使得清扫工作量加大。 Manual drying is labor-intensive and time-consuming, and is also affected by environmental factors. Mechanized drying equipment is widely used in feed factories. However, the heating materials used in existing dryers are diesel, coal, etc., which will cause environmental pollution during the drying process. Contamination, and drying costs are high. Most of the existing dryers are vertical and horizontal fixed cylinder dryers, which will cause uneven heating of corn, low drying efficiency, local overdrying, blackening of corn, and partial drying of corn. The degree of dehumidification is not enough, causing corn mildew. Most of the existing dryers are not equipped with dust removal equipment, which will cause air pollution, especially corn husks, which will fly everywhere without collection and treatment, causing pollution of the entire factory area and increasing the cleaning workload.
因此，有必要对现有的烘干机进行改进，提高粉碎效率，节约能耗，降低噪音。 Therefore, it is necessary to improve the existing dryer to increase the crushing efficiency, save energy consumption and reduce noise.
