[0018] The grain moistening device in the embodiment of the utility model can effectively solve the problems of uneven grain moistening, poor moistening effect and low moistening efficiency in the traditional grain moistening method. The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the utility model.

[0019] Figure 1 As shown, the grain moistening device includes a heating device 1, a circulating fan 2 and a grain moistening bin assembly 3. The heating device 1 is connected to the circulating fan 2 through a pipeline to form a circulation path for hot air. The other end of the circulating fan 2 is connected to one end of the grain moistening bin assembly 3, and the other end of the grain moistening bin assembly 3 is connected to the heating device 1 to form a closed circulation loop.

[0020] The grain moistening bin assembly 3 includes a first heat-insulating pipe 31, a second heat-insulating pipe 32 and a plurality of grain moistening bins 33. The upper end of each grain moistening bin 33 is connected to the first heat-insulating pipe 31 through a first branch pipe 34, and the lower end of each grain moistening bin 33 is connected to the second heat-insulating pipe 32 through a second branch pipe 35. A first airtight butterfly valve 36 is provided on the first branch pipe 34, and a second airtight butterfly valve 37 is provided on the second branch pipe 35, so as to control the opening and closing of the grain moistening bin 33 according to actual needs.

[0021] In some embodiments, in order to keep the temperature of the hot air stable during the circulation process, a third insulation pipe 4 is provided between the circulation fan 2 and the heating device 1, and a first temperature sensor 5 for detecting the return air temperature is provided on the third insulation pipe 4. At the same time, a second temperature sensor 6 for detecting the outlet air temperature is provided on the side of the second insulation pipe 32 close to the heating device 1, and a third airtight butterfly valve 8 is provided on the side of the first insulation pipe 31 close to the circulation fan 2.

[0022] In addition, in order to monitor the temperature conditions in the grain moistening silo 33 in real time, a third temperature sensor 7 is provided in each grain moistening silo 33, and multiple third temperature sensors 7 are provided in each grain moistening silo 33. The third temperature sensors 7 are arranged at intervals along the upper and lower directions of the grain moistening silo 33 so as to detect the temperature at different height positions in the grain moistening silo 33.

[0023] Working principle:

[0024] When working, heat is first generated by the heating device 1, and then blown by the circulating fan 2 to form hot air, which enters each grain moistening bin 33 through the second insulation pipe 32 and the second branch pipe 35. In the grain moistening bin 33, the hot air contacts the grain to moisten the grain, and the humid hot gas enters the first insulation pipe 31 through the first branch pipe 34, and finally returns to the heating device 1 for reheating, forming a cycle.

[0025] By controlling the opening and closing of the first airtight butterfly valve 36 and the second airtight butterfly valve 37, the grain moistening bin 33 can be individually controlled to meet the moistening requirements of different batches or different types of grain. At the same time, by real-time monitoring of the data of the first temperature sensor 5, the second temperature sensor 6 and the third temperature sensor 7, the temperature of the hot air circulation system and the temperature of different positions in the grain moistening bin 33 can be grasped in real time, thereby achieving precise control of the moistening process.

[0026] The utility model moistens the grain by circulating hot air, which not only improves the moistening efficiency, but also ensures the uniformity of moistening, so that the grain can maintain good integrity during grinding, and improves the grinding efficiency and product quality. At the same time, the device has a simple structure, is easy to operate and maintain, and has high practicality and promotion value.
