FAQ

Are you Manufacturer?

Yes, we are production and sales of spray dryer.

How to choose the suitable spray dryer?

1. First of all, we have to consider what industry or material we are going to do, what are the needs, or what we need to pay attention to when drying materials, such as: temperature and what auxiliary materials can be added, etc.

2. When selecting the model, we also need to consider whether we need to enlarge the production at a later stage.

Spray dryer selection introduction:

• The experimental spray dryer is mainly suitable for universities, research institutes and food, medicine, chemical enterprises laboratory production of trace particles of powder, for most of the solution such as emulsion, suspension with broad-spectrum applicability, suitable for the drying of heat-sensitive substances such as biological products, biological pesticides, enzyme preparations, etc., because the sprayed material is only sprayed into a mist size particles only when the high temperature, so only instant heat, can Keep these active materials in the dry still maintain its active ingredients are not destroyed.
• Low temperature spray dryer is suitable for low temperature drying of heat sensitive, viscous, active materials and materials with high sugar content, such as herbal natural product extracts, dairy products, biological preparations, enzyme preparations, raw fruit juice, polymer materials, etc.
• Centrifugal spray dryer is mainly used to rotate the atomizer high-speed rotational force will be thrown out droplets, the same is dried by hot air into powder or particles, when the experimental demand for uniform powder or particles when the centrifugal spray dryer.
• Spray granulation dryer, there are special double air-fed liquid granulation nozzle, directly uniform spherical droplets through uniform heat into particles. Can be adapted to experimental and small-scale production use, good precision of the granule ball, uniform particles. Its characteristics are atomisation head, Qiaofeng double air-fed liquid granulation nozzle; atomisation mode: bottom-up, increasing the time of the droplets in the air; particle size range of 5 microns to 250 microns, granulation particle size adjustable; inner and outer ring of airflow adjustment, can get the satisfactory particle size requirements; tower cap design, more effective retention of the target particles.
• Closed spray dryer specifically for organic solvents, the use of circulating nitrogen and the formation of inert gas medium instead of the usual air medium, to spray drying. In addition to recovering the product, organic solvents can also be recovered. The closed cycle spray system is specially designed for organic solvents with low flash point or slightly toxic, flammable and explosive characteristics.

How to maintenance spray dryer?

Spray dryer equipment in continuous experimental or production use after a period of time, need to carry out a maintenance and maintenance, if not maintenance or maintenance, will cause damage or pollution to some accessories, such as drying tower: if not maintenance cleaning, the inner wall will be covered with the last use of materials and dirt, resulting in drying out the material will have impurities, etc.

1. Daily maintenance cleaning

• Clean the drying chamber of the spray dryer to remove dirt and residual impurities.
• Check whether the pneumatic valve is working normally and whether it is well sealed.
• Check whether the work of each control valve and air pressure regulator is normal.
• Clean the surface of the temperature and pressure instruments of dirt and impurities, and check whether the values displayed on the two instruments meet the specified requirements.
• Check that the steam injector is not making abnormal noises.
• ensure that the motor and condensate pump must run smoothly and without noise.

2. Weekly maintenance

• Clean the drying chamber of the spray dryer and remove rust, scale and impurities.
• Check the air circuit breaker
• Check the cylinder and pneumatic box door, and add lubricant to the slide bar. Ensure that the drying chamber of the spray dryer can have a high degree of sealing.
• Check the working condition of all parts and stop immediately if abnormalities are found to prevent the fault from expanding.
• Check the nozzles of the spray dryer. (5) Check the nozzles of the spray dryer. If it is found that the spray water is not atomized or blocked, it should be repaired or replaced in time; etc.
