Description

Technical Field

[0001] The invention relates to the technical field of grain processing equipment, in particular to a drying implementation method for a grain drying center. Background Art

[0002] Grain drying equipment is often used in grain processing equipment. As we all know, when the temperature and humidity conditions in the environment where the grain is located meet the growth and reproduction of microorganisms, mildew will occur. That is to say, moisture and temperature are two important factors for the reproduction of microorganisms such as mold in grain (i.e., grain mildew). Under normal circumstances, controlling the moisture content of grain below the safe moisture content may prevent the mildew of grain. At present, the method to reduce the moisture content of grain is the spontaneous combustion and drying method. In the main grain producing areas, due to the large output and insufficient drying space, the moisture content of grain purchased by the grain depot often exceeds the safe moisture content, which is the main factor causing the mildew of grain in the grain depot, especially when the grain purchase period is in the cloudy weather; in addition, even if the moisture content of the grain does not exceed the safe moisture content when entering the warehouse, due to the spontaneous combustion and moisture return, the stored grain also needs to be dried regularly to ensure that the grain does not mildew. Due to the limitation of the drying space of the grain depot, the stored grain often cannot be dried on time, resulting in mildew of the grain in the grain depot.

[0003] There are some grain drying equipment in the prior art, but they are all grain dryers with relatively simple functions and cannot handle a large amount of grain that needs to be dried at one time. During the grain drying process, someone needs to perform the feeding and conveying operation separately, which has a relatively low work efficiency; and it is not possible to perform batch moisture content detection on the dried grain, so the quality of grain drying will be uneven. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a drying method for a grain drying center that can realize loading and transportation of multiple grain dryers and can detect the moisture content of grain after drying, thereby improving the quality of grain.

[0005] The present invention is implemented by the following method: a drying implementation method for a grain drying center, the implementation method comprising the following steps:

[0006] Step S1: during use, the rice is transported to the feed inlets of multiple rice dryers through a conveying mechanism;

[0007] Step S2, drying the rice by a rice dryer, and the plurality of rice dryers are controlled by a controller, the plurality of rice dryers are equipped with temperature and humidity sensors, and the temperature and humidity sensors are electrically connected to the controller;

[0008] Step S3, when the drying time of the rice dryer reaches the time set by the user, the temperature and humidity sensor will feed back the temperature and humidity inside each rice dryer to the controller in real time, and then discharge the material. A detection element is provided at the discharge port of the rice dryer to detect the moisture content of the rice;

[0009] Step S4: If the rice temperature and humidity are qualified, the rice is transferred to the next step. If the rice temperature and humidity are unqualified, it proves that the drying degree is not enough.

[0010] The rice is transported back to the rice dryer for further drying, and this cycle is repeated to achieve the drying effect of the rice.

[0011] Furthermore, the conveying mechanism includes a conveying cylinder, a screw conveyor is arranged inside the conveying cylinder, a plurality of discharge hoppers are connected to the left and right sides of the conveying cylinder at equal distances, an opening and closing part is arranged on the discharge hopper, a feed hopper is arranged at the feed port of the rice dryer, and the feed hopper is arranged in coordination with the discharge hopper.

[0012] Furthermore, the opening and closing member includes a support frame, the support frame is arranged on the discharge hopper, a first telescopic cylinder is embedded in the support frame, and an opening and closing plate is arranged at the end of the telescopic rod of the first telescopic cylinder.

[0013] Furthermore, a first exhaust pipe is connected to the upper surface of the rice dryer, and multiple first exhaust pipes are connected to an outlet pipe, the outlet pipe is connected to a filter box, an activated carbon filter plate is arranged at the upper end of the filter box, and a second exhaust pipe is connected to the upper surface of the filter box.

[0014] Furthermore, the detection element comprises a material receiving conveyor belt, which is arranged directly below the discharge port of the rice dryer. The material receiving conveyor belt is divided into multiple detection areas by multiple partitions, and a screening element is arranged in the detection area.

[0015] Furthermore, the partition includes a moisture content detector, and a plurality of gantries are equidistantly arranged on the upper surface of the left and right support plates of the material receiving conveyor belt, a second telescopic cylinder is embedded in the horizontal plate of the gantry, and the moisture content detector is arranged at the end of the telescopic rod of the second telescopic cylinder; the screening component includes a third telescopic cylinder, a plurality of the third telescopic cylinders are equidistantly embedded on the right support plate of the material receiving conveyor belt, a pushing plate is arranged at the end of the telescopic rod of the third telescopic cylinder, and a plurality of discharge hoppers corresponding to the pushing plate are equidistantly connected to the left support plate of the material receiving conveyor belt.

[0016] The beneficial effects of the present invention are as follows: the present invention can realize loading of multiple rice dryers and realize batch transportation of grains, and then can also detect the temperature and humidity of the rice dryer, timely monitor whether the drying conditions have been reached, and timely stop the machine to discharge the materials, so as to achieve energy saving. The detection part can realize moisture content detection after the rice is discharged to detect whether the moisture content of the rice is qualified. In this way, the whole batch of unqualified rice can be dried again, and the quality of the rice can be controlled, the quality of the rice can be improved, and the storage of the rice can be realized. The present invention has a simple structure and is easy to operate, and can effectively save manpower and material resources and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
