It is widely used in pharmaceutical, dentistry, food industry, etc. Anhydrous magnesium citrate needs to be dried during the production process to remove moisture, help maintain the stability of the compound, and prevent decomposition or changes in reaction activity caused by residual moisture.

For example, a drying device for producing low-moisture anhydrous citric acid with publication number CN218155281U is coordinated with a box body, a rotating mechanism, a material receiving box, a driving mechanism, a longitudinal tube, an air outlet and a heating mechanism, and has the advantages of rolling heating of the anhydrous citric acid, uniform heating and high quality of the finished product. It solves the problem that the existing drying equipment for producing anhydrous citric acid can only simply dry the material, and the anhydrous citric acid is piled up, so that the internal material cannot be exposed to heat, resulting in uneven drying of the material, and at the same time, the external material is damaged by excessive heating, which reduces the quality of the finished product. However, in actual use, when drying anhydrous magnesium citrate, the moisture generated by the drying cannot be guided and discharged, and the moisture generated by the drying is mixed with the hot air, which is easy to increase the humidity inside the box during the drying process.

1. Drying components are arranged inside and outside the drying box. When drying anhydrous magnesium citrate, the material is added into the drying box through the feed hopper, and the blower and the exhaust fan are started at the same time. The heating wire on the blower starts to work, so that the blower can blow out hot air to dry the material. The moisture generated by the drying generates thermal expansion after being heated, so that it can float above the inside of the drying box. The driving motor is started to drive the rotating shaft to rotate, and the rotating shaft drives the stirring rod to rotate to turn the material. While the rotating shaft rotates, the rotating rod is driven to rotate through the meshing of the first bevel gear and the second bevel gear, and the rotating rod drives the turntable to rotate, so that the column block rotates in a circle, and then the movable frame can be pushed to move back and forth through the sliding connection of the movable frame, and the air supply pipe is driven to move back and forth through the sliding rod, so that the movable rod moves back and forth, and the movable rod can move back and forth through the rack and the rotating gear during the movement. The cooperation of drives the rotating rod to rotate behind the mounting frame, and then drives the connecting shaft to rotate through the cooperation of the third bevel gear and the fourth bevel gear. After the connecting shaft rotates, the cooperation of the first pulley and the second pulley drives the rotating shaft to rotate, so that the driving gear rotates, and the driving gear drives the movable tube to rotate through the meshing outer gear ring. While the movable tube rotates, it slides in the limiting ring groove through the limiting ring to limit the position, thereby expanding the exhaust range of the exhaust pipe, and can quickly export the moisture above the inside of the drying box. Through the drying component, when drying anhydrous magnesium citrate, the moisture can be exported, and the anhydrous magnesium citrate can be turned over during the drying process, so that the material can fully contact with the hot air, and the moisture extraction range can be expanded, and the moisture inside the drying box can be quickly exported, so as to avoid affecting the drying quality of anhydrous magnesium citrate and improve the drying efficiency.

2. During the drying process, magnesium citrate anhydrous will generate a certain amount of dust due to the turning. The exhaust pipe will export some dust when exporting moisture. The exhaust pipe can guide dust and moisture into the purification box, and the moisture is discharged through the air outlet. The movable rod drives the piston to move back and forth in the cylinder during the reciprocating movement. One end of the water inlet pipe is connected to the water container. When the movable rod drives the piston to move to the left, the one-way valve inside the connecting pipe is closed, and the one-way valve inside the water inlet pipe is opened. The cylinder is vacuumed by the piston to allow water to enter the cylinder. When the movable rod drives the piston to move to the right, the one-way valve inside the water inlet pipe is closed, and the one-way valve inside the connecting pipe is opened, so that the water inside the cylinder enters the diverter pipe through the connecting pipe and is sprayed out through the nozzle, so that the exported dust can be sprayed, and the dust can be treated to reduce dust, so as to avoid the generation of dust that affects environmental hygiene, and avoid inhalation by staff, and avoid direct contact between staff and magnesium citrate anhydrous dust, thereby improving safety.

3. When the sliding rod drives the air supply pipe to move back and forth, the hot air delivery range can be expanded, and the air supply pipe drives the positioning sleeve to slide on the positioning rod during the movement to limit the movement of the air supply pipe. The movement of the air supply pipe can drive the rotating pipe to move. After the rotating pipe rotates, the engagement of the external teeth and the tooth plate can drive the rotating pipe to rotate. When the rotating pipe rotates, the positioning ring drives the positioning ring to slide inside the positioning ring groove to support the rotation of the rotating pipe. After the rotating pipe rotates, the range of hot air delivery can be further improved, so that the hot air can be evenly delivered to the inside of the drying box, which can fully dry the anhydrous magnesium citrate, shorten the drying time, and improve the drying efficiency.

The cylinder 241 is vacuumed by the piston 242, so that water enters the cylinder 241. When the movable rod 217 drives the piston 242 to move to the right, the internal one-way valve of the water inlet pipe 243 is closed, and the internal one-way valve of the connecting pipe 245 is opened, so that the water inside the cylinder 241 can pass through. The dust enters the diversion pipe 244 through the connecting pipe 245 and is sprayed out through the nozzle, so that the exported dust can be sprayed and the dust can be reduced. The sliding rod 215 drives the air supply pipe 213 to move back and forth, which can expand the hot air delivery range, and the air supply pipe 213 drives the positioning sleeve 252 to slide on the positioning rod 253 during the movement, so as to limit the movement of the air supply pipe 213. The movement of the air supply pipe 213 can drive the rotating pipe 247 to move. After the rotating pipe 247 rotates, the rotating pipe 247 can be driven to rotate through the engagement of the external teeth 249 and the tooth plate 248. When the rotating pipe 247 rotates, the positioning ring 251 is driven to slide inside the positioning ring groove 250 to support the rotation of the rotating pipe 247. After the rotating pipe 247 rotates, the range of hot air delivery can be further improved.
