Spray Dryer for Vegetable Powder

Spray dryer for vegetable powder have become vital in the food processing industry and help manufacturers retain the nutritional value, color, flavor, and shelf life of vegetables. This is an innovative drying technique where vegetable extracts in liquid form or purees are converted to powder products by passing hot air over them. It has several advantages and thus the best process suitable for industries that deal with high-quality, stable, and easy-to-store vegetable powders.

A spray dryer for vegetable powder is an innovative technology in the food processing system that is used to produce fine, durable, and easy-to-use vegetable powder from fresh vegetables. It involves the conversion of liquid vegetable extracts or purees into powder form by dehydration of the extract through hot air. This technique also ensures that some nutrients of the vegetables are preserved and that the shelf life is also increased, which makes it a perfect solution for many food manufacturing companies, and the market of healthy food products.

What is Spray Drying?

Spray drying is a single, continuous process in which a liquid feed is converted into a dry powder by evaporative removal of water. It is a technique of reducing a liquid solution or suspension to small droplets, particularly vegetable puree or juice. These droplets are then exposed to hot air inside a drying chamber to evaporate the water content almost immediately leaving behind fine dry particles in the form of powder. This helps to maintain most of the structure, nutrients, and taste of the vegetable, and thus spray drying is very suitable for the production of vegetable powders.

The entire process is very fast and does not require much energy therefore it is used in different industries such as pharmacy, cosmetics, and more so in the food processing industries. Typically for vegetables, spray drying not only enhances shelf stability but also can act as a vehicle for transporting highly potent nutrients in concentrated forms that are portable and lightweight. These vegetable powders can be consumed in various products, such as soups, sauces, seasonings, natural food colors, and dietary supplements.

How Spray Dryer for Vegetable Powder Works

A spray dryer for vegetable powder works on a very basic but efficient mechanism. First, the vegetable material is ready for the purpose and this may involve a process of liquefy, and such methods may include, juicing, pulping, or pureeing the vegetables such as spinach, carrots, tomatoes, or beat. This liquid is then sprayed in the spray dryer the droplets are created by either the nozzle or rotary wheel.

These droplets are further exposed to a hot air jet in the large drying chamber. As the moisture evaporates the droplet quickly becomes powder in the form of fine particles. The collected vegetable powder is separated through a cyclone separator in which the powder is forced out from the air to produce a dry and free-flowing product for packaging.
