Spray Dryer for Fruit Powder

A spray dryer for fruit powder is a necessary piece of equipment in the food processing industry for making high-quality powdered fruits. Through this kind of technology, fresh fruits are processed into free-flowing dry powders ready for use while they retain their nutritional value, colors, and tastes. Fruits that have been sprayed or dried can be used in ways that allow for easier storage, transportation, and cost-effective use in subsequent food production.

The spray drying technology is one of the most revolutionary technologies in the food processing industry mainly in the production of fruit powders. With the trend of using natural products over artificial chemicals in food products, the consumption of fruits in powdered form has gained popularity. Spray dryer for fruit powder have been developed as an economical way of dehydrating fresh fruits with little loss of flavor, color, and nutrients to ready-to-market stable powdery forms.

The Working Principle of a Spray Dryer for Fruit Powder

A spray dryer utilizes the method of drying where a liquid fruit pulp or juice is turned into fine fruit powder. This process involves spraying the fruit mixture with a fine spray or droplets of small sizes by use of a nozzle or rotary atomizer in a drying chamber. To this end, hot air which ranges from 150-200 °C is then passed through the chamber such that the liquid droplets will evaporate immediately. The slurry, which is created because of moistened solid particles, is evacuated from the chamber as soon as the moisture leaves the solid where it forms a small fine powdery substance that sinks to the chamber’s bottom.

The hot air is often discharged and a cyclone separator or a bag filter may be utilized to separate the powder from the airflow so that the fruit powder prepared is dry and, thus ready for packing. The main strength of spray drying is that it does not compromise the nutritional value of the fruit since the drying process is fast and does not expose the fruit to high temperatures for long It also yields an easy-to-re-constitute powder.

Factors to Consider When Using a Spray Dryer for Fruit Powder

Thus, spray dryer for fruit powder can be regarded as a perfect solution to produce fruit powder; however, several factors should be taken into consideration. Processing conditions such as the fruit variety, moisture content, and endpoint temperature consequently influence the quality of the final fruit powder. Some fruits contain a lot of sugar and may also have stickiness issues and this may necessitate the use of additives or carriers such as maltodextrin.

Relative temperature and airflow of the spray dryer also influence the process significantly because high heat temperature destroys natural nutrients and flavors in the fruits and is not preferred by the consumers. On the other hand, if the temperature is low, it may be impossible to dry the product effectively which will in turn have low yields. Hence, defining these parameters is critical to achieving optimal yields of good fruit powder.
