Description

TECHNICAL FIELD

[0001] The utility model relates to an easy-to-clean grain dryer. BACKGROUND

[0002] Grain dryer is a key equipment for drying high-moisture grain, such as rice, wheat, corn, etc., to ensure the quality of grain storage and processing. It adopts a circulating drying process and uses hot air as the drying medium to ensure uniform heating of the grain and excellent quality after drying. A corn processing dryer is disclosed in Chinese Patent No. 202223012142.9, which comprises a box body, a material guiding channel is arranged inside the box body, a material conveying roller is rotatably connected inside the material guiding channel, and a spiral blade is fixedly connected to the side of the material conveying roller. Between every two adjacent spiral blades in the same plane, a paddle is arranged. A sand discharging channel is also arranged inside the box body, and a sand discharging hole is formed in the box body to communicate with the material guiding channel and the sand discharging channel. The corn processing dryer further comprises an electric motor, which is fixedly installed on the box body and has an output shaft fixedly connected to one end of the material conveying roller; a hot air blower, which is fixedly installed on the box body and has an air outlet communicating with an air outlet pipe; a cavity is formed in the material conveying roller, and the other end of the material conveying roller is fixedly connected to an air inlet pipe communicating with the cavity; one end of the air inlet pipe penetrates through the box body and is fixedly connected to a rotary joint; the air outlet pipe communicates with the rotary joint; and a plurality of air outlet holes are formed in the material conveying roller. Figure 1 It can be seen that in the corn processing dryer, the sand discharging hole is arranged at the bottom of the box body, and the impurities in the corn kernels will fall into the sand discharging channel from the sand discharging hole 9. During the continuous corn drying process, due to the different sizes of the impurities, larger impurity particles are prone to accumulate at the bottom of the box body and are not easy to discharge, which may further cause partial blockage of the sand discharging holes, affecting the sand discharging effect and making it difficult to clean.

[0026] This utility model has at least the following beneficial effects:

[0027] The grain to be dried enters the drying chamber through the feed inlet. The stirring component continuously stirs and turns the grain. Hot air injected through multiple hot air holes comes into full contact with the grain to dry it. Afterward, the cooled air, carrying moisture and some dust from the grain, is discharged through multiple discharge holes. Larger impurity particles, under the influence of gravity, are sieved through the discharge holes and fall directly into the discharge channel as the grain tumbles. Even larger impurity particles are concentrated at the bottom of the drying chamber by gravity and do not block the discharge holes. Therefore, the air, after heat exchange and cooling, not only removes moisture and a large amount of fine dust and impurities from the grain when it exits the chamber, but also continuously blows away impurities through the discharge holes with high pressure, effectively reducing the accumulation of impurities, improving grain drying efficiency, and reducing maintenance costs.

[0028] In summary, the easy-to-clean grain dryer provided by this utility model can effectively remove moisture and impurities while drying grain, thereby improving grain drying efficiency and reducing maintenance costs.
