Product Details
How to achieve the drying efficiency?
A good drying efficiency is determined by four factors: drying temperature, residence time, air flow, and dew point. And these four factors are interconnected, and any change in conditions will affect the drying effect.
Drying temperature refers to the temperature of the air entering the drying bucket. Due to the physical properties of each raw material, such as molecular structure, specific gravity, specific heat, moisture content and other factors, the temperature during drying has certain limits. If the temperature is too high, some additives in the raw material will volatilize, deteriorate or agglomerate. If the temperature is too low, some crystalline raw materials will not reach the required drying conditions, such as PC/120 ℃, ABS/80~95 ℃. In addition, insulation and insulation are required in the selection of dry barrels to avoid drying temperature leakage, resulting in insufficient drying temperature or energy waste.
Residence time refers to the pre drying time of raw materials before forming. If the drying time is too long, it can cause the raw materials to deteriorate, agglomerate, or waste energy. If the drying time is too short, it can cause high moisture content. For example: PC/3-4 hours, ABS/3-4 hours.
Air flow is a medium that removes moisture from raw materials, and the size of the air flow can affect the effectiveness of dehumidification. Excessive air volume can cause excessive return air temperature, causing overheating and affecting the stability of the dew point. If the air volume is too small, it cannot completely remove the moisture in the raw material. The air volume also represents the dehumidification ability of the dehumidification dryer.
Dew point temperature refers to the temperature at which a gas cools down to condense the moisture it contains into water droplets. It is a unit used to measure the degree of dryness (wetness) of a gas. The less moisture in the gas, the lower the dew point temperature. A good dehumidification dryer should have a dew point temperature of -40 ℃.
The use of dehumidification dryers can be divided into single machine and centralized type. Single machine dehumidification dryers usually include the dryer host, drying drum, and suction machine. The use of a single unit is suitable for a small amount of diverse drying, with the advantage of good drying efficiency and convenient and fast material replacement. A centralized dryer includes a dryer host and several drying drums, each with an independent heating controller that can simultaneously dry several different raw materials. It is also equipped with an air volume control valve to control the air volume of each drying drum
