With the in-depth research and development of spray drying technology and equipment, more and more spray drying equipment will appear in the market, and the food industry will accelerate its development with broad prospects.Spray dryerDuring homework, it is necessary to ensure that the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product meet the standards in order to achieve the desired effect.

Take the bulk density as an example. In the process of spray drying, the bulk density is one of the important characteristics of food. Each measure should ensure that the bulk density reaches * during the operation. The bulk density is affected by the temperature and humidity of the powder, the feed temperature, the particle size distribution, the temperature of the dry air inhaled, the product discharge temperature, the air contact mode, the type of spray dryer and the position set in the spray dryer. To ensure the ideal stacking density of food raw materials, experienced masters are needed to take charge.

But with the advent of the intelligent era, ifSpray dryerIt can analyze and judge the spray temperature and duration required by materials according to the humidity, location, particle size, etc. of materials, which can greatly reduce the dependence of equipment on people. Although spray drying has no dust problem in the production process, it is easy to produce dust at the product outlet. In addition, it is an indisputable fact that the application rate of thermal efficiency of spray drying equipment is low. Generally, the inlet temperature is about 150 ℃~250 ℃, and the outlet temperature after spray drying is 60 ℃~100 ℃. It can be seen that more than half of the heat energy has not been used. The application of spray drying in the food industry not only overcomes the shortcomings of difficult storage of materials, retains the nutritional value of materials, but also simplifies the production process and avoids dust problems in the drying process.

implementSmall spray dryerAutomatic control can reduce the labor intensity of operators, decrease the number of operators, lower operating costs, and improve the quality of food and medicine after baking. as ifSpray dryerIn the process of powder production, the spray dryer has realized an unmanned system, which canSpray dryerThe key data such as inlet and outlet air temperature, air volume, mud pressure, and moisture inside the system are processed through software to analyze the factors that cause system changes in real time, and can simulate manual operation to adjust the temperature and slurry supply flow rate of the hot blast stove, ultimately replacing human operation. This series of advantages make the small spray dryer improve its vitality. However, with the increase of equipment demand for small spray dryers and the improvement of technical difficulty requirements, the cost of small spray dryers is bound to increase, which is a problem to be solved in the future. The compact design of the small spray dryer can be independently placed in the laboratory or on a specially designed stainless steel rack, which is self-contained and can operate without other facilities. The small spray dryer adopts one button startup and large color LCD touch screen operation. It can adopt two operation modes of * automatic or manual monitoring to facilitate the operation and monitoring of the experimental process.
