Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature drying, in particular to a low-temperature drying device for rice processing. Background Art

[0002] The rice dryer is used for rice with high moisture content after harvest. In order to make the rice meet the conditions for safe storage (without mildew), the moisture content of the rice must be reduced to a safe moisture content for storage (that is, 12% is the safe moisture content for rice storage) to reduce the moisture content.

[0003] However, such drying devices in the prior art, such as a drying device for rice processing in Chinese patent application number 202322348738.4, cannot continuously dry the grains when in use. When a large amount of grains are waiting to be dried, this device can only store a portion of the grains for drying at a time, and then pour out the grains for drying again. In this way, the overall drying efficiency is low, and the grains cannot be dried continuously. Therefore, an improved low-temperature drying device for rice processing is needed to address this problem. Utility Model Content

[0020] A scraper 8 is fixedly provided on the outer surface of the upper end of the rotating disk 7, and the scraper 8 makes it easier for the rotating disk 7 to drive the grains on the upper end of the rotating disk 7 to rotate; then the grains are thrown away by centrifugal force to disperse the grains, which makes it easier to carry out subsequent hot air drying.

[0021] The upper end of the transmission pipe 2 is fixedly provided with a feed port 9, through which the grains to be dried can be conveniently added into the transmission pipe 2; then the spiral transmission rod 3 inside the transmission pipe 2 can be used to transmit the grains to the upper end of the rotating disk 7;

[0022] A draw plate 10 is provided at one side of the lower end of the drying bin 1, and the draw plate 10 can seal the drying bin 1. When the grains in the drying bin 1 need to be released, the draw plate 10 is opened, so that the grains can leak out from the draw plate 10 under the action of the downward force.

[0023] A guide block 11 is fixedly provided at the lower end of the drying bin 1, and the guide block 11 can conveniently guide the grains to be discharged to the draw plate 10 for discharge;

[0024] The discharge port 4 is located at one side of the upper end of the rotating disk 7, so that the grains discharged from the discharge port 4 can fall on the upper end of the rotating disk 7 and will not appear at the center of the rotating disk 7, which makes it easier for the grains to be thrown out by the centrifugal force.

[0025] Working principle: When using this device, the hot air connecting pipe 12 needs to be connected to the hot air blower, so that the hot air connecting pipe 12 can blow out hot air of suitable temperature, and then the hot air can flow upward from the lower end of the drying bin 1; when the grains need to be dried later, the grains to be dried can be added to the transmission pipe 2 through the feed port 9; then the spiral transmission rod 3 inside the transmission pipe 2 can be used to transmit the grains to the upper end of the rotating disk 7; at this time, the motor 6 is turned on and the rotating disk 7 is driven by the motor 6 to rotate at a high speed. At this time, the scraper 8 makes it easier for the rotating disk 7 to drive the upper end of the rotating disk 7 The grains are rotated; in this way, the grains can be thrown out by centrifugal force to disperse the grains, which is convenient for subsequent hot air drying. After that, when the dried grains are accumulated in a layer at the lower end of the drying bin 1, the draw plate 10 can be opened to allow the grains to flow out. In this way, the upper end continuously enters the grains to be dried, and the lower end continuously discharges the dried grains. In this way, the device can form continuous drying work, thereby greatly improving the drying efficiency. At the same time, during drying, the centrifugal force can be used to throw the rice away to disperse the rice, which is convenient for subsequent hot air drying.
