| Operating instructions for plastic pellet dryer: plastic pellet dryer operation control panel![]() 2. Setting of drying temperature: Press the mode switch key twice according to the instruction, when the drying temperature setting display shows the unit symbol of °C, you can set the temperature to be dried by pressing "△". 3. The operation of conveying material can be divided into one-time, two-time and three-time conveying operation. Press the corresponding conveying operation/stop button and number of times according to different times. Example: Once the conveying material is running, press the conveying 1 run/stop key, and the indicator light flashes quickly at this time. When the conveying 1 run/stop button is pressed again, the indicator light slowly dims, when the indicator does not flash, it means Full barrel. The second and third conveying operations can be deduced by analogy. 4. When the plastic pellet dryer is automatically operated to feed materials from the drying cylinder to the hopper of the molding machine, first turn on the conveying 1 to keep the material in the drying cylinder full, and then press conveying 2 or 3 to feed the material from the drying cylinder to the hopper of the molding machine. When the material in the hopper is full, the sensor indicator light on the hopper is on, and the conveying 2 (conveying 3) indicator light is on at the same time. 5. If an abnormality occurs during the use of the plastic pellet dryer, the alarm will sound, and the abnormal code will be displayed on the monitor. Press the power button to confirm the alarm and the alarm will stop. When the abnormality is eliminated, the alarm code will be eliminated by pressing the reset button. 6. When the warning light flashes, please check whether the raw materials have been used up, or enter the system console panel to check whether there is a problem, and correct it in time. (Automatic error correction function) Precautions for plastic pellet dryer: Points for attention when using the plastic pellet dryer:1. The plastic pellet dryer should be cleaned frequently and kept clean. The dehumidifier should be placed in the center of the room. The air inlet and outlet of the refrigerated dryer should not be blocked by obstructions, and the air filter should be cleaned. When the ambient temperature is lower than 15℃, the water droplets attached to the evaporator surface will freeze and the dehumidifier effect will be weakened. If the ambient temperature exceeds 40℃, the pressure in the system will increase and the compressor will overload. At this time, the overload protector The circuit should be cut off, otherwise the compressor motor will be damaged. So the best temperature range for dehumidifier is 15℃~40℃. If the humidity in the air is below 30%, it will be too dry and uncomfortable, so a reliable humidity controller will control it to maintain the range of 50% to 60%. When in use, close doors and windows as much as possible to achieve dehumidification in the room. The body of the desiccant dryer must be placed flat, not tilted or turned sideways, to avoid machine failure or abnormal noise. 2. The water storage in the desiccant dryer is too full. In order to avoid overflowing and contaminating the ground, when the machine body must be moved during operation, please unplug the power cord first, and then pour out the water in the water storage bucket. After moving the dehumidifier, it is best to put it statically for four to six hours before starting to use it. Because the compressor pipeline in the dehumidifier contains cold coal, it must take four to six hours to return the cold coal to its original position after being moved. 3. Clean the air filter regularly (about once every two weeks) to maintain the dehumidification and dust removal efficiency and life of the machine. Clean the air filter and wash it with water below 40°C; it is better to clean it with detergent. After washing off the dust, rinse it with water, dry it in the shade and put it back into the body. When cleaning the body, wipe it gently with a damp cloth; avoid directly splashing water for cleaning, so as not to damage the electrical insulation. Adhesives on the surface of the body can be cleaned with soap and water. Avoid spraying with gasoline, petroleum spirit, solvent or spray insecticide to avoid peeling paint or discoloration. Do not use thin rods or iron wires to dig out the inside of the machine to avoid malfunction or danger. Please unplug the power cord to maintain the life of the machine when it is out of power, not used for a long time, or when traveling.
