When thousands of materials need to be spray-dried, their chemical composition and physical properties are very different, so so far, spray drying is still said to be a technique, which is true to a certain extent. In the process of estimating and designing the characteristics of the spray dryer, it is difficult to express the actual characteristics of the material and its motion state in the drying tower with theoretical formulas. Therefore, practical experience often plays a big role. The parameters and parameters in the design process are difficult to express with theoretical formulas. Past experience is often different from theoretical research. At present, the characteristic estimation and design of spray dryers are not based solely on theoretical analysis, but also rely on experimental data and the practical experience accumulated by manufacturers over a long period of time.

When you choose a spray drying equipment supplier, the following factors should be considered:
* First of all, you need to have a comprehensive understanding of the supplier to see whether it has the ability to serve you.
* It is necessary to conduct detailed and comprehensive technical exchanges with the supplier's engineering and technical personnel to see whether his technical level in this area is capable of tailoring for you to meet the actual production requirements.
* Whether the supplier is familiar with the characteristics of the customer's materials, especially in aspects such as pre-processing that it is not involved in.
* Comprehensively understand the supplier's production scale and successful cases in the fields involved for reference.
* Whether the supplier can provide customers with test conditions? Before placing an order, do the test in advance and be aware of it.
* Check whether the supplier fully considers objective conditions for equipment operation and energy consumption during the design and theoretical calculation process. A good supplier should stand from the customer's perspective, minimize energy consumption, and strive to create benefits for the enterprise.
* Fully understand the supplier's customer service capabilities, customer service philosophy, and inventory status of spare parts.
* Be able to personally visit the customer's office provided by the supplier to understand the supplier's reputation status and the actual production status of the equipment.
* When purchasing equipment, first look at the materials, configuration, and system integrity.

A good supplier and customer should be a partnership, where both parties work together to create wealth.
