Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, and more specifically, to a drum-type rye seed drying device. Background Art

[0002] Rye is an annual or biennial herbaceous crop of the genus Secale in the Poaceae family. Rye grains are long and narrow, with pointed embryo ends and darker color, mostly brown or grayish-blue. After cleaning, rye seeds need to be dried. Various types of seed drying devices have appeared in the prior art. For example, the patent document with publication number CN218722985U discloses a rapid drying device for rice seed processing. The device uses a hot air blower to transport hot air into the interior of the air inlet bin. The hot air enters the collection bin and is sprayed into the inner bottom of the drum from the air jet holes. The driving device is then controlled to drive the drum. The drum rotates at a constant speed, causing the rice seeds inside the drum to tumble continuously, and the hot air ejected from the air jet holes is continuously sprayed onto the tumbling rice seeds to heat and dry them, so that the rice seeds can be heated evenly, thereby ensuring the drying effect of the device on the rice seeds. However, the seed material in the above-mentioned dryer cannot be subjected to the multi-effect turning effect during drying, so the wind-receiving surface, wind-receiving angle and wind-receiving intensity of the seed material cannot be changed cyclically, which results in limited improvement in the drying efficiency of the species. Based on this, the utility model provides a drum-type rye seed drying device to solve the problems raised in the above-mentioned background technology. Utility Model Content
