Description
技术领域 technical field
本实用新型技术属于茶叶加工设备技术领域，具体涉及一种微波和热风一体式茶叶干燥装置。 The technology of the utility model belongs to the technical field of tea processing equipment, and in particular relates to a microwave and hot air integrated tea drying device.
背景技术 Background technique
茶叶是一种著名的保健饮品，尤其是绿茶，其保持了鲜绿的色泽和天然有益健康的成分，深受广大民众的喜爱绿茶，绿茶的加工需要经过摊青、杀青、理条、做形、提毫、炒干、精选等多个步骤才能完成。炒干是绿茶加工的关键工序。目前，我国多数绿茶产品的干燥操作是在单一干燥设备内，在一种干燥参数下完成的。从物料干燥动力学特性可以看出，物料在不同的干燥阶段，其最优干燥参数是不同的。采用单一干燥设备和单一干燥参数，不仅造成能源与资源的浪费，还会影响茶的品质，如高温处理，由于失水速度快，没有类似烘干的较长受热作用，化学成分转化不充分，苦味的花青素也不能得以适量转化;再则受热强弱不匀，因而炒干的味尚浓带苦，不够醇，另外受热不均匀，热效率低的问题，造成茶叶叶绿素被破坏，使茶叶发黄，影响了茶叶的质量。 Tea is a well-known health drink, especially green tea, which maintains its bright green color and natural and healthy ingredients, and is deeply loved by the general public. , Lifting, frying, and selection can be completed through multiple steps. Stir-frying is a key process in green tea processing. At present, the drying operation of most green tea products in my country is completed under one drying parameter in a single drying equipment. From the dynamic characteristics of material drying, it can be seen that the optimal drying parameters of materials are different in different drying stages. The use of a single drying equipment and a single drying parameter not only causes a waste of energy and resources, but also affects the quality of tea. For example, high-temperature treatment, due to the rapid water loss, there is no longer heating effect similar to drying, and the chemical composition is not fully transformed. Bitter anthocyanins cannot be transformed in an appropriate amount; moreover, the intensity of heating is uneven, so the taste of frying is still strong and bitter, not mellow enough. In addition, the problem of uneven heating and low thermal efficiency causes the chlorophyll of the tea to be destroyed, making the tea Yellowing affects the quality of tea.
因此，生产中急需一款新型组合干燥方式的烘干设备，来实现物料在不同干燥阶段，采用不同干燥参数和干燥方式，提高能源利用率和茶叶烘干的品质和效率。 Therefore, there is an urgent need for a new type of drying equipment with combined drying methods in production to realize the use of different drying parameters and drying methods in different drying stages to improve energy utilization and the quality and efficiency of tea drying.
