Freeze Dryer For Broccoli

Freeze Dryer Supplier Freeze Dried Vegatables Broccoli

The broccoli freeze dryer is a device used to freeze-dry fresh broccoli. Through freeze-drying technology, the water in the broccoli is removed at low temperatures, thereby maintaining its original nutrients, color, shape and flavor. The freeze-dried broccoli is light in weight, easy to store and transport, and has a greatly extended shelf life.

Working Principle
Freezing process: Fresh broccoli is first quickly frozen to an extremely low temperature, usually at -40°C or lower. This step ensures that the cell structure and nutrients of the broccoli are not destroyed during the freezing process.
Sublimation drying: Under a vacuum environment, the water in the broccoli is directly converted from solid to gas through sublimation, avoiding the formation of liquid water, thereby maximizing the retention of the nutrition and appearance of the broccoli.
 Main components
1.Vacuum system: Maintain a low-pressure environment to ensure that the water can sublime at low temperatures.
2.Refrigeration system: Provides the low-temperature environment required for rapid freezing, usually using an efficient compressor or liquid nitrogen system.
3.Heating system: Provides the right amount of heat during the sublimation process to help evaporate water and maintain the texture and nutrition of broccoli.
4.Control system: The freeze dryer is equipped with an automated control system that can accurately adjust the temperature, vacuum and drying time to ensure the stability and consistency of the production process.

Features

1.Optional nitrogen generator can effectively utilize the heat generated during the nitrogen production process while enjoying the inert material protection, and the most efficient energy saving;

2.low-temperature vacuum drying oven can choose steam, hot water and other heat sources for heating;

3.The ice layer of cold hydrazine becomes thinner and the refrigeration energy consumption decreases with high condensation efficiency.

4.The design of the Freeze Dryer For Broccoli box through the heating plate layer has a larger heating area than the conventional vacuum box, and the heating is more uniform;

Technical parameters
Processing capacity: Depending on the type and size of the freeze dryer, the processing capacity ranges from a few kilograms to dozens of kilograms, suitable for production needs of different scales.
Condenser temperature: Usually below -50℃, used to capture and condense sublimated water vapor.
Drying time: The freeze-drying time of broccoli is usually between 12 and 24 hours, depending on the thickness of the broccoli flakes and the initial moisture content.
Advantages
1.Nutrient retention: Freeze-drying technology can maximize the retention of nutrients such as vitamins, minerals and antioxidants in broccoli, far better than other drying methods.
2.Extended shelf life: The freeze-dried broccoli is almost completely free of moisture and can be stored for a long time under vacuum packaging conditions, with a shelf life of up to several years.
3.Lightweight and easy to store: The freeze-dried broccoli is light in weight and small in size, which is convenient for long-distance transportation and storage, and is very suitable for export or long-term storage.
4.Good rehydration effect: Freeze-dried broccoli can quickly restore its original shape and taste after rehydration, which is close to the quality of fresh broccoli.
