simple description:When choosing a desiccant dryer process, it is of vital importance to identify the drying performance of the material. Materials can be divided into two types: hygroscopic and non-hygroscopic. Hygroscopic materials can absorb moisture from the surrounding environment, while non-hygroscopic materials cannot absorb moisture from the environment. For non-hygroscopic materials, the moisture existing in any environment remains on the surface, becoming "surface moisture" and easy to be removed. However, rubber particles made of non-hygroscopic materials may also become hygroscopic due to additives or fillers.
Convection dryer can use a hot air dryer to dry non-hygroscopic materials. Because the water is only loosely constrained by the interfacial tension between the material and the water, it is easy to remove. The principle of this type of machine is to use a fan to absorb the air in the environment and heat it to the temperature required to dry a specific material. The heated air passes through a drying hopper and heats the material by convection to remove moisture.
It is generally best to use microwave drying equipment for drying hygroscopic materials: the first drying section focuses on the inside of the material; the second drying section evaporates the moisture on the surface of the material. At this time, the drying speed slows down and is dried. The temperature of the material begins to rise; in the last stage, the material reaches a moisture absorption balance with the dry gas. At this stage, the temperature difference between inside and outside will be eliminated.

simple description:Check the fault:
Check the evaporator, the condensed water on the surface is uniform and it is proved that there is no blockage;
Inspecting the condenser, there is no large temperature difference between the tubes, which proves that the condenser is not clogged;
The compressor will automatically stop after working for a period of time, while the fan operation and control system are normal;
Check the compressor's overheating protection, there is no action; it is estimated that the compressor is faulty, and the protector in the compressor has acted, causing the compressor to automatically stop. The inspection found that the winding resistance when the compressor was just stopped was different from the resistance value when the compressor was cold. |

| simple description:The desiccant dryer should be cleaned and kept clean from time to time. 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 clean. When the ambient temperature exceeds 15°C, the water droplets covering the surface of the evaporator will freeze and the effect of the dehumidifier will be weakened. If the ambient temperature exceeds 40°C, the pressure in the system will increase and the compressor will expand. Cut off the line, otherwise the compressor motor will be damaged. Therefore, the best operating temperature range of the dehumidifier is 15°C~40°C. If the humidity in the air is below 30%, it is too dry and uncomfortable. Therefore, a reliable humidity controller takes control to maintain the range of 50% to 60%. When in use, the doors and windows are adjusted and closed, so that the indoor dehumidification effect can be achieved. The body of the desiccant dryer must be placed, not tilted or down, to avoid machine failure or abnormal noise. |

simple description:Four determinants of drying efficiency of desiccant dryers
An outstanding dehumidification dryer has the following 4 factors to determine the drying power: drying temperature DryTemperatur, drying time Residtime, airflow, and temperature Dewpoint. These four elements are interlocked, and any change in conditions will affect the drying effect. |

simple description:The temperature value of the plastic desiccant dryer after drying
Plastic desiccant dryers are mainly used for monotonous and highly hygroscopic plastics. Plastic desiccant dryers send the dehumidified low dew point air into one or more standard drying hoppers to advance the drying power and shorten the monotonic time. The dehumidification dryer uses a fan to draw moist air into the machine and passes through the heat exchanger. At this moment, the moisture in the air condenses into water droplets and becomes dry air to be discharged out of the machine. This cycle reduces the indoor humidity. |

simple description:Analysis of thAnalysis of the reason why the desiccant dryer can not dry materials normally
Analysis of the reason why the desiccant dryer can not dry the materials normally, is now widely used with engineering plastics. Dehumidifying dryers have gradually replaced traditional hot air dryers and are widely used in industrial production. The use of dehumidification dryers can be divided into stand-alone and centralized. Stand-alone dehumidification dryers generally include a dryer host, a dehumidifying dryer barrel, and a suction machine. The single-machine application is suitable for a small number of various types of drying, and its advantages are good drying efficiency and convenient and quick reloading.e reason why the desiccant dryer can not dry materials normally |

simple description:Monotonic temperature of desiccant dryer
It refers to the temperature of the air entering the monotonous barrel. Each material is due to its physical properties, such as molecular structure, specific gravity, specific heat, transmittance and other factors. When the temperature is monotonous, the temperature is allowed to be bound. When the temperature is too high, the range is partially added. Transpiration and agglomeration are too low and some crystalline materials cannot meet the required monotonous conditions, such as: PC/120℃, ABS/80~95℃. |
