TOPTION spray dryer is a type of continuous atmospheric dryer. The liquid material is sprayed into mist with special equipment to make it contact with hot air and be dried in only a few seconds. The spray drying equipment is widely used to dry some heat sensitive liquids, suspensions and viscous liquids, such as milk, eggs, tannins and medicines. It is also used for drying fuels, intermediates, soap powder and inorganic salts, etc.

Here we are mainly talking about two different drying methods of instant coffee, freeze drying and spray drying. From the figure below, we can also clearly see the difference. Freeze drying obtains irregularly shaped large-grain coffee powder, the result of spray drying is a fine powder with very good particle uniformity. Instant coffee dried by different processes has different advantages, let’s take a look at it.

With the changes in the market economic environment, many of our customers in the plant essential oil extraction industry are gradually enthusiastic about TOPTION this type affordable essential oil extraction equipment. Not only is the extraction equipment economical price, but also the operation is very simple. One person can complete the entire essential oil extraction process, does not require the assistance of others, which not only to help you save oil extraction equipment procurement costs, but also to save labor costs. Let us take a brief look at TOPTION this essential oil extraction equipment together.

Spray drying technology is most suitable for producing solid powder or particle products from liquid materials, such as solution, emulsion, suspension and pumpable paste states, for this reason, when the particle size and distribution of the final products, residual water contents, mass density and the particle shape must meet the precise standard, spray drying is one of the most desired technologies.

Spray drying machine is popular used for milk powder, instant coffee powder, orange juice powder, egg powder, etc. Professional powder making machine, material drying only need several seconds, so most suitable for drying the heat sensitive materials.

Fish oil is rich in all-cis high-unsaturated fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). This ingredient has good physiological activity, not only has the functions of lowering blood fat, lowering blood pressure, inhibiting platelet aggregation, lowering blood viscosity, but also anti-inflammatory, anti-cancer, and improving immunity, etc. It is considered to be a potential natural and functional food.

Let a mixture liquid which is containing solid particles, evaporate through spray drier finally become a solid powder.

Freeze drying profess is finished under low temp, especially suitable for heat-sensitive material, can prevent the isolation membrane contraction.
