Key points to note when using a vacuum dryer
1. Vacuum dryers without explosion-proof or corrosion-proof chambers must not be used to dry flammable, explosive, or corrosive substances. If the items being dried are moist, a filter should be placed between the vacuum chamber and the vacuum pump to prevent moisture from entering the pump and causing malfunction. If the dried items are lightweight and small (small particles), a screen should be placed at the vacuum port inside the chamber to prevent the dried material from being sucked in and...
Principle of spray drying equipment
Among various drying equipment, spray dryers are one of the most widely used, used for drying solutions, suspensions, or slurries.

Can spray dryers be used to dry bacterial solutions?
Spray dryers can be used to dry bacterial solutions. A spray dryer is a device that can simultaneously dry and granulate liquids. It uses specialized equipment to spray liquid materials into a mist, which then comes into contact with hot air and is thus dried. This equipment is particularly suitable for drying some heat-sensitive liquids, suspensions, and viscous liquids, including bacterial solutions. In practical applications, spray dryers are widely used to dry various bacterial solutions,...
How to control the burner of a hollow paddle dryer
1. Regarding the burner of this hollow dryer, its proportional control produces high flame temperature and efficiency, but it is not suitable for many applications, including low-temperature processes. Low-temperature processes typically have range ratios of 20 to 1, 30 to 1, or even higher for heat dissipation requirements. In proportional control systems, the burner is difficult to operate, with heat output range ratios greater than 10 to 1, making it difficult to control the flow rate...
