摘要
目前粮食干燥方式受限于环境和人工条件,极大地限制了粮食加工行业的发展,因此,寻求高效的干燥技术与装备成为粮食加工行业发展的重要目标。梳理了国内外空气源热泵干燥技术与装备的研发应用现状,以系统控制和工艺参数为研究对象,研究空气源热泵干燥技术的装备结构与工作原理,分析了干燥装备存在的干燥不均匀、能耗大、效率低等问题产生的原因,并探讨了相应改善方法;针对多重组合干燥技术,分析了微波、太阳能与远红外3类与空气源热泵干燥技术联合方式下的干燥优势,探讨了联合干燥技术相较于单一干燥技术在装备和工艺中存在的优势和不足。结合干燥行业发展问题,从联合干燥技术研究方向、联合干燥工艺改进、干燥信息平台搭建、干燥设备研发升级4个方面对联合干燥在粮食干燥领域进行了展望,以期为干燥领域发展和装备创新提供参考。
At present,grain drying methods are limited by environmental and artificial conditions,which greatly restricts the development of the grain processing industry.Therefore,seeking efficient drying technology and equipment has be-come an important goal for the development of the grain processing industry.This paper summarizes the research and ap-plication status of air source heat pump drying technology and equipment at home and abroad.Taking the equipment structure and working principle of air source heat pump drying technology as the research object,it analyzes the reasons for problems such as uneven drying,high energy consumption,and low efficiency in drying equipment and discusses the corresponding improvement methods.It also discusses the advantages and disadvantages of combined drying technology compared to single drying technology in terms of equipment,processes,and other aspects.Based on research directions,improvement of joint drying processes,construction of drying information platforms,and equipment research and devel-opment policies,the development of joint drying technologies in the field of grain drying is expected to provide a refer-ence for the development and equipment innovation in the drying field.
