Drying temperature of the drying equipment has what effect on the material

The drying temperature of the drying equipment has various influences on the material, and these influences are directly related to the product quality and production efficiency. The following is a detailed analysis of these effects:

First, the impact of physical and chemical properties of the material
Burning or deterioration:
Excessive drying temperature may lead to material scorching or deterioration, especially in the heat-sensitive materials more significant. Scorched products not only look bad, but also may affect its physical and chemical properties and activity.

Color change:
Some materials will undergo color changes at high temperatures, such as oxidation, browning, etc., which will affect the appearance and quality of the product.

Destruction of activity:
High temperature may destroy the activity of the active ingredients in the material, resulting in a decline in product quality.

Second, the impact of drying efficiency
Accelerated water evaporation:
In general, higher drying temperature can accelerate the evaporation of water, thus improving the drying efficiency.

Surface hardening:
However, too high a temperature can lead to the surface hardening of the material too quickly, but rather hinder the diffusion of internal moisture, thereby reducing the drying efficiency. Especially in the spray drying process, too high a temperature can lead to droplet surface hardening, increasing the risk of sticking to the wall.

Third, the impact on the product recovery rate
Incomplete drying:
Too low a drying temperature may result in the material not being fully dried, thus affecting the product recovery rate. Products with high moisture content may not meet quality standards and need to be rejected or reprocessed.

Over-drying:
High drying temperatures may result in over-drying of the material, resulting in a loss of quality. Over-dried products may become weak, brittle or cracked, thus affecting their integrity and end use.

IV. Impact on Equipment
Equipment Aging:
Prolonged operation at high temperatures accelerates equipment aging and wear, e.g. bearings, seals and other wear parts may fail due to high temperatures.

Increased energy consumption:
In order to maintain a high-temperature environment, the need to consume more energy, which not only increases production costs, but also may have a negative impact on the environment.

V. Impact on operational safety
Fire risk:
Excessive temperatures may cause fire or explosion and other safety incidents, especially when handling flammable and explosive materials is more dangerous.

Personnel injury:
The high temperature environment may pose a threat to the health of the operators, such as burns and heat stroke.

To summarize, the drying temperature of drying equipment affects the material in many ways, including the physical and chemical properties of the material, drying efficiency, product recovery rate, equipment life and operation safety. Therefore, in actual operation, the drying temperature should be set reasonably according to the nature of the material, drying requirements and equipment performance and other factors, in order to ensure product quality and production efficiency, and at the same time, to protect the safe operation of the equipment and the health of the operators.
