Grape freeze dryer 

The nutritional composition of grape grape is not only delicious, but also has high nutritional value. The sugar content of grapes in mature berries is as high as 10% - 30%, mainly glucose. A variety of fruit acids in grapes help digestion. Eating more grapes appropriately can strengthen the spleen and stomach. Grapes contain minerals such as calcium, potassium, phosphorus, iron, a variety of vitamins B1, B2, B6, C and P, as well as a variety of amino acids needed by the human body. Regular consumption of grapes is of great benefit to neurasthenia and excessive fatigue.

Eating an appropriate amount of fresh grapes every day will not only reduce the risk of cardiovascular disease, but also be particularly beneficial to the health of patients with ischemic heart disease and atherosclerotic heart disease. Flavonoids in fresh grapes can "clean" the blood and prevent the formation of cholesterol plaque. The darker the grapes are, the more flavonoids they contain, but if the grape skin and grape seeds are eaten together, it has a better protective effect on the heart.

Grape freeze dryer processing technology includes the following steps:

1. After washing the fresh grapes without mechanical damage and diseases and pests, moisturize them in the environment of 35-45 ℃ and 80-100% relative humidity for 30-60min;

2. The grapes treated in step 1 were pre cooled at 2-4 ℃ for 30-60min;

3. When the pre cooled grapes are placed at 20-25 ℃, uniform wrinkles appear on the surface of the grape skin;

4. Immerse the grapes in the pretreatment solution in step 3, take them out and dry them;

5. The grapes in step 4 were vacuum freeze-dried. The eutectic point temperature was - 15.5 ℃, the pre freezing temperature was - 35 ℃, 2h, the primary drying temperature was - 20 ℃, the pressure was < 100Pa, 12h, the secondary drying temperature was 55 ℃, the pressure was < 100Pa, 6h.

6. After freeze-drying, take out the freeze-dried grapes and seal them for storage.

The freeze-dried grapes processed by food freeze-drying machine can not only speed up the freeze-drying speed of grapes, shorten the freeze-drying time and maintain the shape of grapes, but also maintain the pleasant flower aroma, fruit aroma and fresh flavor of grapes.
