Small spray dryers currently face four major problems

Spray drying equipment can be divided into centrifugal, pressure and airflow according to the structure of the netomizer.
food dried with a small spray dryer can be a solution, slurry or paste, but must be pumped.
food materials need to be atomized before they can be exchanged for heat in the drying chamber.
droplets formed by the spray are very small, which provides a considerable heat exchange area, allowing the evaporation process to take place quickly.
Small spray dryer is currently facing four major problems: First, the phenomenon of sticky walls become the number one problem sticky wall phenomenon is a prominent problem hindering the normal operation of spray dryers, rich in animal fat food materials tend to be deposited on the drying chamber wall.
over time, these food items will gradually become a source of pollution, endangering food health. The main reason for the
sticky wall phenomenon is that the wall temperature of the spray dryer is too high to make the product sticky, so the drying chamber is changed to a mezzanine structure to improve cooling efficiency;
, the size is too large to face the placement problem the size is too large to face the restrictions of the placement area.
Small spray dryer prices with people's attention to food production conditions, many food enterprises have built 300,000 or 100,000 levels of dust-free purification workshop, but spray dryer because of the large size, can not be placed in the whole clean area, many enterprises will choose to collect the part of the material in the clean area, the rest of the place elsewhere.
this situation, it is necessary to spray drying equipment system to improve the closed performance and prevent external environmental pollution.
3. Material control can be intelligent to change the spray dryer in the operation of the finished product particle size distribution, residual moisture content, accumulation density and particle shape in line with precise standards, the resulting particles can get the desired results.
the accumulation density as an example, in the spray drying process, the pile density is one of the important characteristics of food, in the operation of each measure to ensure that a good stack density.
the density of the reactor is related to powder temperature and humidity, feed temperature, particle size distribution, inhalation dry air temperature, product discharge temperature, air contact mode, sprayer type and position set in the spray dryer, etc.
, environmental protection and energy-saving problem is the most urgent spray drying although in the production process without dust trouble, but in the production of products easy to produce dust.
The thermal efficiency application rate of other spray drying equipment is an indisputable fact, the general feed port temperature is around 150 degrees C to 250 degrees C, the outlet temperature after atomization and drying is 60 degrees C to 100 degrees C, it can be seen that most of the heat energy has not been used up.
