1. Finned tubes.
The finned tube is the core component of the steam finned tube radiator, and its performance directly determines the heat exchange efficiency of the radiator. The main function of the finned tube is to increase the heat dissipation area through the fins and improve the heat transfer efficiency. In the process of preserved fruit drying, the high-temperature steam passes through the fin tube to transfer heat to the fins, and then exchanges heat with air through the fins, so as to achieve the drying effect.
Finned tubes are typically made of metal, such as copper, aluminum, or stainless steel, which have good thermal conductivity and corrosion resistance. The shape and arrangement of the fins will also affect the heat dissipation effect, and the common fin shapes are straight fins, corrugated fins, etc. Reasonable fin design can increase the heat dissipation area and improve the heat exchange efficiency, resulting in faster drying speed and higher drying quality.
2. Steam distribution system.
The steam distribution system is another important component of the steam finned tube radiator, its main function is to evenly distribute the steam into each finned tube, ensuring that each finned tube can get enough heat. The design of the steam distribution system has a direct impact on the flow distribution and heat transfer of the steam.
A steam distribution system usually consists of a steam main pipe, branch pipes, and connectors. The steam supervisor is responsible for transporting the steam from the steam source to the branch tubes, which distribute the steam evenly into each finned tube. To ensure uniform steam distribution, the design of the branch pipe needs to take into account factors such as pressure, flow and resistance of the steam.
3. Temperature control system.
The temperature control system is one of the key components of the steam finned tube radiator, and its main role is to monitor and control the temperature during the drying process. Through accurate temperature control, it can ensure that the preserved fruit is heated evenly during the drying process, avoiding over-drying or under-drying, so as to ensure the quality and taste of the product.
Temperature control systems typically consist of temperature sensors, controllers, and actuators. The temperature sensor is responsible for monitoring the temperature in the drying chamber in real time and transmitting the temperature signal to the controller. According to the difference between the set temperature and the actual temperature, the controller controls the actuator to adjust the flow or temperature of the steam, so as to achieve precise control of the temperature in the drying room.
Fourth, the supporting structure.
The supporting structure is the frame and foundation of the steam finned tube radiator, and its main role is to support and fix the finned tube, steam distribution system and temperature control system and other components to ensure the stability and safety of the entire radiator.
Support structures are usually made of metal materials, such as angle steel, channel steel, etc., which have sufficient strength and rigidity to withstand the weight of finned tubes and working loads. At the same time, the design of the supporting structure also needs to take into account the installation, maintenance and overhaul of the radiator, so as to facilitate the subsequent operation and management.
5. Synergy between components.
During the preserved fruit drying process, the various components of the steam finned tube radiator need to work together to achieve efficient heat transfer and temperature control. The steam is evenly distributed to each finned tube through a steam distribution system, which transfers heat to the fins and exchanges heat with air for a drying effect. The temperature control system monitors and controls the temperature in the drying room in real time to ensure that the preserved fruits are heated evenly and achieve the desired drying effect. The support structure provides stable support and foundation guarantee for the entire radiator. Steam finned tube radiator
