Abstract

The invention discloses a combined type solar dryer which comprises at least one dryer unit. According to the combined type solar dryer, a vacuum tube solar heat collector is utilized to absorb solar energy and heat a heat accumulation medium, and then the heat accumulation medium heats air in a drying chamber so as to achieve the purpose of drying materials in the drying chamber. The combined type solar dryer is flexible in usage mode, applicable to both low-temperature ranges and high-temperature ranges, and usable on powered or powerless occasions; and meanwhile, the combined type solar dryer can be used alone in the form of one single drying unit or can be used in a large-scale mode by combining and connecting a plurality of the drying units to form a large system, and conveyor belts can be used in upper and lower drying layers of the combined long drying system so as to facilitate circular operations of drying a large quantity of materials.

Description

technical field

[0001] The invention belongs to the technical field of solar light and heat utilization, and in particular relates to a combined solar dryer. Background technique

[0002] While there are various solar dryer designs, each is designed for a single purpose. For example, it is only applicable to a fixed temperature range, or only applicable to occasions with external power, or only applicable to occasions without external power, and its capacity is generally fixed. However, in fact, some users are faced with changing usage conditions, which requires a flexible and changeable solar dryer, and there is a lack of corresponding products on the market. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a combined solar drier with simple structure and flexibility, so as to meet the needs of users in various occasions in actual use.

[0004] In order to solve the above-mentioned technical problems, the prese...
