Pharmaceutical Chemical Food Powder Spray Dryer

Based on differences in drying methods, structural design, and applicable materials, liquid material dryers can be divided into several mainstream types, each with its unique advantages and applicable scenarios:   1. Spray Dryer: Suitable for various solutions, emulsions, suspensions, and pastes, especially widely used in the food (e.g., milk powder, coffee powder) and pharmaceutical (e.g., antibiotic powder) industries. Its advantages include fast drying speed (typically only a few seconds to tens of seconds), uniform particle size, good flowability, and the ability to achieve continuous production.   2. Rotary Drum Dryer: Available in single-drum and double-drum structures, suitable for processing high-viscosity, high-solids-content liquid materials (e.g., starch slurry, yeast paste, feed paste). During operation, the drum rotates at a certain speed, its surface contacting the heating medium (steam). The liquid material is evenly adhered to the drum surface by a distributor and scra…
