Freeze drying of instant food can retain the nutrients and taste of food to the greatest extent through low temperature and vacuum environment. The freeze-dried products after production can be rehydrated very quickly. Unlike traditional instant noodles, porridge, and dried mushrooms, which need to be soaked or steamed before they can be eaten, freeze-dried instant food is convenient and quick to eat.
Freeze drying of instant food sublimates and dries the food in a low-temperature vacuum environment to retain the nutrients, color, flavor and shape of the food to the greatest extent. The equipment integrates refrigeration system, vacuum system, heating system and intelligent control system, and automatically controls the temperature and vacuum degree during the freeze drying process through the freeze drying curve to ensure the stability of each batch of products. The temperature control range of the partition is wide (-30℃ to +80℃), and the ultimate vacuum can reach 10Pa, which can meet the freeze drying needs of various instant foods, such as freeze-dried rice, freeze-dried noodles, freeze-dried soups, etc.
Compared with traditional drying methods, the low-temperature vacuum environment avoids the damage of high temperature to the heat-sensitive components of food, and retains the natural nutrition and active substances of food. The freeze-dried food is porous sponge-like, with good rehydration, which is convenient for consumers to eat quickly. In addition, freeze-dried food has a low moisture content (<3%) and can be stored for a long time at room temperature without adding preservatives, which greatly extends the shelf life and reduces transportation and storage costs.
KASSEL freeze dryer has an intelligent operation interface, which can set and store freeze drying curves through the PLC control system, and achieve one-button start and automatic operation. It is also equipped with a data traceability function to ensure the controllability and traceability of the production process. Whether it is a small-scale trial production or large-scale industrial production, KASSEL freeze dryer can provide efficient and stable solutions.
