Industrial fruit dryer machine
Industrial fruit dryer is an industrial equipment specially used for drying fruits. Its main function is to remove moisture from fruits through drying technology to achieve the purpose of preservation and processing. Fruit dryer is suitable for dehydrating and drying various fruits and can maintain the original color, taste and nutrients of the fruits.
PALET supports customization of various types of industrial dehydration machines, including hot air dryers, vacuum dryers, freeze dryers, etc.
Process of drying fruit
The processing and drying process of different types of fruits may be different, so the fruit dryer can be designed with a variety of drying methods: hot air drying, vacuum drying, and freeze drying. Let’s take a look at their drying processes.
Hot air drying
Hot air drying is a commonly used drying technology, mainly used to remove moisture from materials. Its basic principle is to directly transfer heat and moisture through hot air, so that the moisture in the wet material evaporates, thereby achieving the purpose of drying.
The advantages of hot air drying include simple operation, relatively low cost, and wide applicability. However, its disadvantages also include high energy consumption, slow drying speed, and some materials may be denatured or lose nutrients due to high temperature.
Vacuum drying
Vacuum drying is a drying technology that removes moisture from a substance by reducing the ambient pressure. In a vacuum environment, the boiling point of water is lower than that of normal pressure, so moisture can evaporate at a lower temperature. This method is widely used in drying heat-sensitive substances, processing of medicines, preservation of food, and drying of some industrial products.
Under vacuum conditions, moisture evaporates more easily, thus speeding up the drying process. By reducing adverse reactions such as oxidation and discoloration, it helps to maintain the appearance and nutritional content of the product. Low pressure conditions can inhibit the growth of certain microorganisms and extend the shelf life of the product.
Freeze drying
Freeze drying is a process of rapidly freezing a substance at low temperatures, usually between -50°C and -80°C, so that its moisture is converted into ice, and then the ice is sublimated into water vapor in a vacuum environment to obtain a dry product. Freeze drying can effectively maintain the shape, color, nutrients and flavor of the substance. The shelf life of the product is greatly extended.
