Hot air system for the pharmaceutical industry

2023/03/04

The hot air system is a very important process system in the pharmaceutical industry. It mainly sends heated air to the drying equipment to evaporate the moisture in the equipment, so as to achieve the purpose of drying materials. Below we will introduce the basic composition and working principle of the hot air system in the pharmaceutical industry.

First, the basic composition of the hot air system

  1. Heat source: The heat source of the hot air system mainly includes electricity, steam, natural gas and other forms.

    Among them, steam is the most commonly used heat source, and its reliability and economy have been widely recognized.

  2. Heat exchanger: The heat exchanger is the key equipment that transfers the heat energy of the heat source to the hot air system, mainly including tube heat exchangers and plate heat exchangers.

  3. Air delivery system: The air delivery system is the core part of the hot air system, mainly including fans, air ducts, regulating valves and other equipment.

  4. Control system: The control system includes temperature controllers, humidity controllers, electric valves and other equipment, which are used to monitor and adjust various parameters of the hot air system.

Second, the working principle of the hot air system

The working principle of the hot air system in the pharmaceutical industry is to heat the air through a heat exchanger, and then transport the hot air to the drying equipment to evaporate the moisture, thereby achieving the purpose of drying the material.

Specifically, the hot air system sucks in the outside air through the fan, and after filtering and heating, it transports the heated air to the drying equipment.

In the drying equipment, the air passes through the surface of the material to take away the moisture, and after dehumidification, it returns to the heat exchanger for reheating.

It should be noted that when using the hot air system, it is necessary to select appropriate temperature and humidity parameters according to different materials to ensure the drying effect and material quality. At the same time, it is also necessary to pay attention to the stability and reliability of the control system to ensure the normal operation of the hot air system.

In short, the hot air system in the pharmaceutical industry is a very important process system. It heats the air and transports the hot air to the drying equipment to evaporate the moisture, thereby achieving the purpose of drying the material.
