Problems solved by technology

If the harvested rice is not dried in time, the rice tends to become soft and have a slight musty smell, and then the husks are wet and ash-colored, turning white, producing aflatoxin, which will be poisoned and even fatal after human consumption
The existing rice drying device is to pile up the rice for drying. This drying method has a small area of ​​contact with each grain of rice, and cannot fully dry each grain of rice. The drying efficiency is not high, and the waste gas generated during the drying process is directly discharged. , no waste gas reuse
In addition, the heating and drying of the conveying process is realized by installing a heating plate on the surface of the conveying device. Since the heating plate only heats the contact surface, the hot air with humidity formed after heating cannot be diffused in time, which is not only inefficient, but also and not completely dry

Abstract

The invention provides a spiral rice circulation drying exhaust gas secondary utilization device, which is characterized by comprising a support, wherein a drying buffer bin, a discharge bin and a packing auger conveying machine are erected on the support and are arranged side by side; a feeding bin is arranged on the drying buffer bin; a hollow air guiding cylinder is arranged in the center in the drying buffer bin, and is perpendicular to the bottom part of the drying buffer bin and the bottom part of the feeding bin; and a spiral conveying pipe is arranged at an outer wall of the hollow air guiding cylinder. The spiral rice circulation drying exhaust gas secondary utilization device provided by the invention is simple in structure, firstly pre-screens and pre-dries rice, then fully utilizes a spiral structure for enabling the rice to freely roll on a conveying face of the spiral conveying pipe, and utilizes hot air to enter in the spiral conveying pipe so as to fully dry each face of each rolled rice through air holes, and exhaust gas produced during a drying process is processed through a dust collection device so as to be secondarily utilized for pre-drying the rice in a reserve bin, so that the rice drying efficiency is improved, the energy consumption is reduced, and the enterprise cost is reduced.

Description

technical field [0001] The invention relates to the technical field of crops, in particular to a spiral type paddy cycle drying waste gas secondary utilization device. Background technique [0002] Moisture is an important chemical component in rice. Moisture in rice not only has a great influence on the physiology of seeds, but also has a great influence on the processing and storage of rice and the value of rice. If the harvested rice is not dried in time, the rice tends to become soft and have a slight musty smell, and then the chaff is wet and grayed, turning white, producing aflatoxin, which will be poisoned and even fatal after human consumption. The existing rice drying device is to pile up the rice for drying. This drying method has a small area of ​​contact with each grain of rice, and cannot fully dry each grain of rice. The drying efficiency is not high, and the waste gas generated during the drying process is directly discharged. , no reuse of exhaust gas. In a...
