Products Description
KFD series vegetables freeze dried machine are manufactured through standardized production processes. Its scope of application can not only freeze-dry vegetables, such as freeze-dried onions, freeze-dried green onions, freeze-dried mushrooms, freeze-dried tomatoes, freeze-dried green beans, freeze-dried broccoli), but can also be widely used to freeze-dry various foods, Chinese herbal medicines, and probiotics. Bacteria and health products, etc. We have selected high-quality materials widely recognized in the industry and imported main components, such as food-grade SUS304 stainless steel materials and German wilo water pumps, which have large lift and good stability. German Bitzer compressors have low energy consumption and high refrigeration efficiency. At the same time, we adopt high-tech manufacturing processes to ensure that the equipment fully complies with GMP standards
How to freeze dry vegetables?( freeze drying brocolli)
1. Vegetable cutter: dicing of broccoli
2. Cleaning and color protection machine: Cleans the surface of the broccoli from contaminants and protects the broccoli from color change.
3. Blanching: Blanching activates the enzyme activity in the vegetable, which helps to preserve the color and prevent color change due to oxidation. In addition, blanching slows down the enzymatic activity of the tissues and helps maintain the texture of the broccoli.
4.Drain the surface of broccoli: Drain the surface water to avoid too much water leading to too long freeze-drying time and increase the load of vegetable freeze-drying machine
5. Vacuum freeze dryer system: pre-freezer, freeze dryer, transportation trolley;
5.1Pre-freezing library: put the drained water of the broccoli into the pre-freezing library of the vegetable freeze dryer for about 4 hours of freeze drying, with the pre-freezing temperature at about -40℃, until the center of the broccoli is completely frozen into ice cubes.
5.2Vacuum Freeze-drying Machine: Put the frozen broccoli into the vacuum freeze-drying bin, after 18~22h of vacuum drying, the water in broccoli is removed, and the moisture content of freeze-dried broccoli is between 5%~10%.
Packing, Coding
Kassel Vegetable Freeze Dryer meets GMP requirements, the whole machine is made of SUS304 stainless steel; Vegetable Freeze Dryer can control the whole broccoli freeze-drying process through Siemens PLC electronic control system, and carry out the freeze-drying data recording, storing, tracking (e.g. freeze-drying temperature, freeze-drying time, freeze-drying vacuum) and authority management for the process of freeze-drying broccoli, and all the freeze-drying data and the freeze-drying process curve can be printed out and used for the process. All freeze-drying data and process curves can be printed out for the optimization of freeze-drying process.

FAQ
1.Are freeze-dried vegetables any good?
Freeze-dried vegetables are able to retain their nutrients, including vitamins and minerals, relatively well during the freeze-drying process. This allows freeze-dried vegetables to provide a degree of nutrition similar to that of fresh vegetables.
