As we all know, each drying equipment has its specific scope of application, and each kind of material can find several kinds of drying equipment that can meet the basic requirements, but the most suitable one can only have one kind. If improperly selected, users must not only bear unnecessary one-time high procurement costs, but also pay a heavy price during the entire use period, such as low efficiency, high energy consumption, high operating costs, poor product quality, and even equipment devices. It can't work normally.
The role of automatic control in the dryer is getting bigger and bigger, but its one-time investment is also the issue that people are most concerned about. Sometimes the investment in control equipment even exceeds the investment in the mechanical part of the dryer. It is also the subject that research should be carried out to determine a reasonable control plan for dryers and drying process requirements and to determine appropriate control measures for specific drying projects.
In addition, it should also pay attention to the magnification of drying equipment. The enlargement involves disciplines such as fluid mechanics, mechanics, thermodynamics, heat transfer, materials science, dust removal, corrosion protection, electrical appliances, and control. It is very likely that some problems will arise during the amplification process. Therefore, the amplification of the drying device is by no means a simple geometrical enlargement.
In this respect, it largely depends on the experience of industrialization, the mastery of the physical properties of materials and the understanding of drying equipment. The phenomena that may occur during the enlargement process should be predicted rationally and objectively, and corresponding solutions can be proposed. The so-called research amplification effect is to grasp the drying theory and drying technology while paying attention to accumulating practical experience and summing up lessons.
The dryer lacks the combination of self-control technology and drying equipment
At present, the low level of automation of domestically produced drying equipment and the backwardness of control means are common problems. As far as the current level of automation is concerned, it is not difficult to solve the control problem in the drying equipment, but what is lacking most is the problem of the reasonable combination of the automatic control technology and the drying equipment. Different materials require different dryers. Similarly, there are major differences in the requirements for control methods for different materials.
