What is drying?
Modern drying method is to use technical machines to dry agricultural products. From the most rudimentary dryers, up to the present time, we can easily find multifunctional, extremely modern and advanced agricultural dryers.
Manufacturers also offer a wide range of high-quality drying systems, also known as drying lines, which operate fully automatically and produce output, not only in the production of dryers. The quality of agricultural products is very high, the nutrients are not changed. Therefore, more and more food processing facilities and processing factories are choosing modern drying systems for agricultural products.
Advantages of the drying method:
Currently, to dry agricultural products, people use many different drying methods. The traditional drying method is still applied to a number of agricultural products such as rice, corn, potatoes… This method is a form of natural drying of agricultural products. Agricultural products are thinly sliced or seeded and sun-dried to a certain degree. However, this simple traditional drying method increasingly shows disadvantages, reduces agricultural productivity and especially takes a lot of time.
The advent of modern dryers and drying systems has overcome the above disadvantages. The current drying method has outstanding advantages and is widely used in many provinces. Farmers, businesses and processing facilities no longer have to rely on the weather, do not need to spend too much time and energy, and still get the desired output of dried agricultural products.
Modern drying lines operate very quickly, operate smoothly and reduce the risk of causing environmental pollution to a very low level. Many types of dryers allow people to dry a very large amount of agricultural products in one drying, drying products, ensuring no mold or termites. The system also operates safely and securely, without causing difficulties for those directly involved in the management of the drying process.
Working principle of drying process
Drying is a very complex mass transfer process. They have solid phase involvement. This process includes both internal and external diffusion of the solid material. Simultaneously, heat transfer takes place. This is a continuous process, not separate. In other words, this process will convert the amount of water in the material from the liquid phase to the vapor phase. Finally separate the vapor phase from the starting material.
The driving force behind this process is the moisture difference. The difference is inside and above the surface of the material. Phase transition diffusion will be applied on the surface of the material. The standard is greater than the partial pressure of water vapor in ambient air.
