Drying vegetables and fruits in factories is one of the old and effective methods for preserving food for long periods without the need to use chemical preservatives. In our modern era, this process has developed significantly thanks to innovative technologies that contribute to preserving the nutritional value and fresh flavor of dried foods.

In this article, we will review the different methods of drying vegetables and fruits in factories, the health and commercial benefits of this process, in addition to modern technologies that have revolutionized this industry such as freeze drying. We will also explain how ProNano Food Industry Consulting can provide its advice to those interested in establishing a vegetable and fruit drying factory.

Methods of drying vegetables and fruits in factories

Sun drying

Sun drying is one of the oldest methods used in drying vegetables and fruits, as food materials are exposed to direct sunlight until the water evaporates from them. Despite the simplicity of this method, it depends greatly on weather conditions and may take a long time. For this reason, this method is used less in large factories that are looking for higher efficiency and speed.

Hot air drying

Hot air drying is the most common method in factories. This method relies on passing hot air over vegetables and fruits, which causes water to evaporate quickly. This method is more efficient than solar drying and allows control of temperature and humidity, ensuring the quality of the final product.

Microwave drying

Microwave drying is a relatively advanced technology, as it uses microwave radiation to directly heat the water inside vegetables and fruits, which causes it to evaporate quickly. This method is characterized by its speed of implementation and better preservation of the color and flavor of vegetables and fruits than traditional methods.

Freeze drying (freeze drying)

Freeze drying or freeze drying is one of the most advanced and effective technologies in drying vegetables and fruits. This technology relies on first freezing food products and then removing the ice from them under low pressure, which completely preserves their chemical and biological composition. This method is ideal for preserving sensitive vitamins and nutrients, and it contributes to the production of high-quality food products with a long shelf life.

Benefits of drying vegetables and fruits in factories

Preserving nutritional value

One of the most prominent benefits of drying vegetables and fruits in factories is preserving the nutritional value of these products. Thanks to modern technologies such as freeze drying, vitamins and minerals can be preserved to a great extent, making dried products a healthy choice for individuals.

Increased shelf life

The drying process helps reduce the water content in vegetables and fruits to very low levels, which limits the activity of bacteria and fungi and extends the shelf life of the products. This means that these products can be stored for long periods without the need for refrigeration or the use of preservatives.

Reducing logistical costs

Drying vegetables and fruits greatly reduces their weight and size, which facilitates the transportation and storage process. This reduces logistical costs and allows factories to meet large orders at a lower cost.

Product diversity

Drying vegetables and fruits opens up a wide variety of products. Dried products can be used in many industries such as bakery, chocolate, and baby food, providing factories with various business opportunities.

Modern Technologies in Drying Vegetables and Fruits

Freeze Drying

Freeze drying is the latest and most advanced technology in the field of drying vegetables and fruits. This technology relies on freezing the product and then removing the water through sublimation under low pressure. This process preserves the sensory and nutritional properties of vegetables and fruits, making it an ideal choice for foods that need to maintain their quality for a long time.

Electric pulse drying

This technology relies on the use of strong electrical pulses to break down the cells in vegetables and fruits, which facilitates the process of extracting water from them. This method allows products to be dried faster while maintaining their nutritional value.
