Dry cocoa solids are the components of cocoa beans remaining after cocoa butter, the fat component, is extracted from chocolate liquor, roasted cocoa beans that have been ground into a liquid state. Cocoa butter is 50% to 57% of the weight of cocoa beans and gives chocolate its characteristic melting properties. Cocoa powder is the powdered form of the solids sold as an end product. Pure natural cocoa powder appears to be light brown, while normal alkalized cocoa powder is darker and brownish red. Cocoa milk powder contains flavanol antioxidants, amounts of which are reduced if the cocoa is subjected to acid-reducing alkalization. Health benefits have been attributed to cocoa flavonoids.
High speed centrifugal spray drying is the most widely used process in liquid shaping technology. It is suitable for producing powder and granules solid products from solution, emulsion, soliquoid, and pumpable paste materials. Therefore, when the particle size, final moisture, bulk density and granules shape meet the accurate standard, centrifugal spray drying is a ideal drying process.
The high speed centrifugal spray dryer supplied by XINGGAN with the features of fast drying speed, well dispersed, stable operating, simplified working process. The applicable raw material can be solution, slurry, emulsion, suspension, paste, melting material, or even caky material.
Applications
Food Industry: fatty milk powder, cocoa milk powder, substitute milk powder, Amino acid, vitamin, egg white (yolk), oats, chicken juice, bone powder, protein, soybean, peanut protein, blood powder, soy sauce powder, coffee, instant dissolvable tea, glucose, pentadiene carboxylic acid, pectin, flavours, vegetable juice, yeast, starch, etc.
Main Characteristics
1. The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95%-98% of the water can be evaporated instantly, and the drying time is only a few seconds, which is especially suitable for the drying of heat-sensitive materials.
2. The product has good uniformity, fluidity and solubility, high purity and good quality.
3. Simplified production process and convenient operation and control. For liquids with a moisture content of 40-60% (up to 90% for special materials), the liquid can be dried into powder products at one time, without crushing and screening after drying, reducing production procedures and improving product purity. The product particle size, bulk density and water content can be adjusted by changing the operating conditions within a certain range, and the control and management are very convenient.

Components of Cocoa Powder Centrifugal Spray Dryer
The cocoa powder spray dryer equipment is composed of five parts: feeding system, heating system, drying tower system, receiving system, and electric control system.
1. Feeding System:
The peristaltic pump can evenly deliver the slurry to the atomizer, and the feeding speed can be automatically adjusted.
Features: Driven by a DC brushless motor, stable feeding and silent operation. It has the functions of displaying the rotating speed and quantifying the speed.
The atomizer is an electric atomizer with water cooling device, frequency conversion control, bearings and other accessories are all well-known domestic brands. The line speed of the atomizer is> 120 m/s. The atomizer is vertical blades and the material is fed in a rectangular channel. It can quickly turn the slurry into a mist continuously and uniformly, and the surface area of the particles is enlarged to form a good heat exchange with the clean hot air, so that the moisture is instantly evaporated and vaporized by the induced draft fan to draw out and empty.
2. Heating System:
The drying air entering the tower through the electric heater is air filtered. The primary filter and the intermediate filter are non-woven fabrics to prevent flying insects from entering the tower. The heating process uses electric heating to complete the heating process to meet the heat requirements of the entire system with enough heat.
3. Drying Room:
The drying chamber is composed of hot air volute, hot air distributor, air disperser, inner tower body, tower body frame, outer tower body, discharge pipe, insulation material, observation cleaning door, lamp hole, etc. The clean air filtered by the air filter enters the hot air volute through the electric heater and hot air pipe, and enters the drying tower evenly through the hot air distributor. The hot air distributor can adjust the rotation angle according to the characteristics of the material to control the stay of the material time.
4. Receiving System:
The main material collection system of this equipment is collected by the cyclone separator, part of the fine material is collected by the secondary cyclone collector, and the discharge port is equipped with a manual butterfly valve to collect the material from the collecting barrel.
5. Electronic Control System:
The complete spray drying equipment is controlled by a standard electronic control system, which can achieve the following functions:
1). Stable start, safe and reliable operation of the motor.
2). According to the process logic of the whole set of drying equipment, set up various auxiliary equipment and effectively deal with abnormal conditions.
3). Make the inlet temperature be a certain set constant process value, the outlet temperature and the feeding pump are interlocked control, and the outlet temperature is adjusted by the size of the feeding amount.
