1. In the coffee production line, YPG Pressure Spray Dryer is widely used for drying coffee extract to coffee powder.    2. General description of spray drying: Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts. Air is the heated drying medium; however, if the liquid is a flammable solvent such as ethanol or the product is oxygen-sensitive then nitrogen is used   All spray dryers use some type of atomizer or spray nozzle to disperse the liquid or slurry into a controlled drop size spray. The most common of these are rotary disks and single-fluid high pressure swirl nozzles. Alternatively, for some applications two-fluid or ultrasonic nozzles are used. Depending on the process needs, drop sizes from 10 to 500 µm can be achieved with the appropriate choices. The most common applications are in the 100 to 200 µm diameter range. The dry powder is often free-flowing     Spray Drying is still the most economical method of evaporation to reduce a liquid feed to solid powder particles. Powder remaining one of the most versatile methods of preservation and cost effective in both storage and transportation of finished goods.       3. Application in coffee extract spray drying: In general, the moisture content of coffee extract is 50%~60%, and moisture content of coffee power is 3%~4%. And drying temperature is about 220°C~260°C. Spray Dryer is one of the main products in our company. And our engineer has rich experience in coffee spray drying, he stayed in Indonesia for 5 years. Many coffee spray drying tower in Indonesia are designed and manufactured that guided by him. Welcome to visit our company and have a face to face discussion with our engineer, and visit our workshop.   Following is a PID diagram of coffee spray drying:       And following are pictures of one coffee pressure spray dryer we made in Indonesia:         4.
