Standard operating procedures for use, maintenance and repair of high efficiency boiling dryer

1 use 1.1 operation preparation (1) to check whether there is "intact" certificate of equipment (2) check whether the power supply, air source and steam source are normal (3) push in the hopper car and lock it (4) press the main power supply, the "power" signal light is on, and press "on the top cylinder" to lift the material roof and make the cylinder sealed (5) press "fan on" and stop immediately after 5 seconds of wind Check whether the direction of fan is correct (6) restart the fan, adjust the pressure regulating valve of the damper, check whether the opening and closing of the damper are flexible, check and adjust the effect of the damper through the negative pressure gauge, and check whether the cylinder is closed (7) press "lighting" and "manual vibration", observe whether the vibration device is normal from the mirror window, press "automatic vibration", and it should work with the drying equipment in cross operation (8) after the inspection, turn off the fan, put down the top cylinder, turn off the power supply and air source, and carry out normal production 1.2 operation procedure (1) put down the catch rack, install a clean catch bag, and lift the catch rack to the first locking position (2) push in the hopper car, press the "top cylinder" to lift the material roof, seal the cylinder, press the "power supply" to power on, adjust the air inlet temperature indicator to the specified temperature, press the "fan" to start the fan, rotate the pressure regulating valve on the panel, and make the fan open to form a boiling bed (3) observe the negative pressure and boiling of the system (4) when the exhaust temperature reaches the discharge temperature, turn off the fan and dry the product for about 20 minutes (5) manually shake the bag 1015 times (6) turn off the power (7) press "top cylinder down" to lower the hopper and pull out the hopper car (8) clean all materials in batches according to cleaning SOP after drying 2 Maintenance and lubrication (1) the equipment shall be regularly added with edible vegetable oil in the oil mist dispenser to lubricate the cylinder (2) regularly discharge the water vapor in the gas water separator (3) after several months of operation, check whether the shaking cloth bag is damaged and whether the sealing strip is damaged If it is damaged, replace it (4) if the equipment is idle and unused for some reason, it shall be started every 30 days for at least 1 hour to prevent the air valve or cylinder from being damaged due to excessive lubrication and drying.
