A filter tube is connected to one end of the air inlet pipe.

The beneficial effects of this utility model are: discharging valves are installed on the inlet and outlet at the upper and lower ends of the silo to seal and isolate the silo, and allow external moisture to contact the melon seeds. In addition, the melon seeds are dried by cooling circulating air. While cooling the melon seeds, the moisture in the melon seeds is removed; at the same time, the transfer tube can be evacuated to lock the freshness of the melon seeds.

Detailed ways

As shown in Figures 1 to 3, the melon seed transfer silo includes a silo 3. The top and bottom of the silo 3 are equipped with a first discharge valve 1 and a second discharge valve 7 respectively. The upper and lower ends of the silo 3 pass through dehumidification pipes. 17 is connected, a circulating air pump 16 and a condensation box 9 are installed on the dehumidification pipe 17. A condenser 11 is provided in the condensation box 9. The condenser 11 is connected to the chiller 12, and the lower end of the condensation box 9 passes through a drainage pipe.

When the utility model is in use: the melon seeds are sent into the silo 3 through the belt conveyor and the bucket elevator for temporary storage. The unloader is closed, so the melon seeds temporarily stored in the silo 3 can be isolated from the outside world. At the same time, the circulating air pump 16 and the chiller 12 can be started to use the condensed and dry air to cool down the melon seeds in the silo 3 and remove the melon seeds at the same time. The moisture absorbed during the transportation process, after the melon seeds are dehumidified and dried, open the valve on the drain pipe to drain the condensed water.

Between the circulating air pump 16 and the condensation box 9, the dehumidification pipe 17 is connected to the exhaust pipe through a three-way solenoid valve 14, and a first solenoid valve 13 is installed on the exhaust pipe. During factory holidays, when melon seeds need to stay in the transfer silo 3 for a long time, you can switch the three-way solenoid valve 14 and open the first solenoid valve 13 to connect the silo 3 to the outside world, and then start the circulating air pump 16 to align the transfer silo. 3 is vacuumed. When the pressure in the transfer silo 3 reaches -0.08Mpa, the circulating air pump 16 is stopped and the first solenoid valve 13 is closed, so that the melon seeds can be stored in a vacuum environment to prevent oxidation of the melon seeds and lock the melon seeds. fresh.

A second solenoid valve 10 is installed on the drainage pipe. A temperature and humidity sensor 15 and a pressure sensor 18 are installed on the silo 3. The pressure sensor 18 and the temperature and humidity sensor 15 are connected to the input end of the controller. The three-way solenoid valve 14 and the first The solenoid valve 13, the second solenoid valve 10, the chiller 12 and the circulating air pump 16 are connected to the output end of the controller. The controller is a PLC controller with a temperature and humidity sensor 15 that detects the temperature and humidity of the melon seeds in the transfer silo 3 in real time. When it is detected that the temperature and humidity of the melon seeds exceed the preset value, the circulating air pump 16 and the chiller 12 are started to control the melon seeds. Carry out cooling and dehumidification.

When the factory is off work or on holiday, the controller controls the three-way solenoid valve 14, the first solenoid valve 13 and the circulating air pump 16 to evacuate the transfer silo 3, and at the same time cooperates with the pressure sensor to maintain the pressure of the transfer silo 3. Between -0.07Mpa~-0.09Mpa.

Every 48 hours, the controller controls the second solenoid valve 10 to open for 3 minutes to drain the condensed water in the condensation box 9 .

There is a jacket 5 outside the silo 3. The lower end of the dehumidification pipe 17 is connected to the jacket 5. Inside the jacket 5, there are multiple air inlet pipes 6 connected to the silo 3. Each air inlet pipe 6 is evenly spaced around the axis of the silo 3. distributed.

One end of the air inlet pipe 6 is connected with a filter pipe 4 . This structure can expand the air intake range of the circulating air pipe, making the air intake more uniform, so that the melon seeds can be evenly dried and cooled.
