Kale is a nutrient-rich vegetable, containing a large amount of vitamins A, C, B2, and a variety of minerals, especially high in calcium, iron, and potassium. Among them, the content of vitamin C is very high, with 153.6220 milligrams of vitamin C per 100 grams of tender leaves, which can be compared with broccoli. Its caloric value is only 209 joules, making it an ideal food for fitness and weight loss. It can be stir-fried, cold-mixed, or made into soup. In Europe and the United States, it is often used with various vegetables to make salads. The flavor is fresh and light, and it remains a beautiful bright green after cooking. However, fresh kale is not easy to preserve and is affected by the season. Dehydrated kale is made by washing, drying, and other processing methods.

Freeze-dried kale processing process:

Selection and cleaning:

First, use a six-station selection conveyor to select fresh and pest-free kale.

Then, use a bubble washer to wash the kale and remove the surface dirt and impurities.

Cutting:

Use a cutting machine to cut the kale into appropriately sized pieces or slices to facilitate freezing and subsequent use.

Blanching:

Send the cut kale into the blanching machine for blanching for 1-2 minutes. This step is to kill bacteria and enzymes, and to maintain the color and nutritional components of the kale.

Cooling:

Quickly send the blanched kale into the cooling machine for cooling to prevent overcooking and loss of nutrients.

Dewatering:

Use a vibrating water machine to drain the water from the cooled kale to ensure that no excessive ice crystals are produced during freezing.

Packaging:

Put the drained kale into plastic bags or frozen boxes, and try to squeeze out the air from the bags to reduce oxidation.

Freezing:

Put the packaged kale into the freezer to freeze.

Storage:

Frozen kale can be stored for several months, but it is recommended to consume it within 3 months to ensure the best taste and nutritional components.
