How to dry raisins and how to dry raisins

How to keep raisins dry:

1.In order to get the best preservation and drying of raisins, scientific research can prove that it is necessary to keep the room relatively dry, and it is better to control the moisture and humidity between 40% and 50%. With such moisture and humidity, the preserved raisins are optimal in terms of taste and color.

And the retention of sugar is also the most suitable degree.

2.Raisins should be stored at the right temperature.

The preservation of raisins should pay attention to the best temperature, the temperature is too high, the water of the raisins will evaporate, at this time the raisins will become unusually shriveled, the taste is not good, and the raisins that are too shriveled do not look good. Therefore, a suitable temperature is required, and after long-term research, it has been found that keeping the temperature at about 26 degrees Celsius is the best storage time.

3.Raisins can also be stored in the refrigerator.

If you open the bag, you need to store the raisins in the refrigerator for best preservation. Because of the open raisins, because they are rich in sugar and sweet smell, they are easy to attract all kinds of small insects. Over time, raisins can be damaged.

Put the grapes into the drying tray, expose to the sun for about 10 days, when the surface is partially dry, you can turn it all over, wet a little on the surface layer to continue to dry, until two-thirds of the fruit is dry, when the fruit is not exuded by hand, you can stack the tray, dry in the shade for a week. In sunny weather, the total drying time is about 20-25 days.

The fruit bunches are stacked for 15 to 20 days to dry evenly, and at the same time the fruit stalks are removed, and the finished product is made.

In order to speed up drying and shorten the evaporation time of water, lye treatment can be used. Impregnated in a solution of sodium hydroxide with a concentration of 1 5 banknotes, thin skins can also be treated with sodium carbonate or a mixture of sodium carbonate and sodium hydroxide with a concentration of 3 6 seconds, and the raw materials are immediately rinsed in clean water after alkali immersion.

Raw materials: grapes, lye appropriate amount.

1. Raw material selection: Dried grapes should be selected with thin skin, plump and soft flesh, beautiful appearance and high sugar content;

2. Cut the bunches: After harvesting, cut off the fruits that are too small and damaged, and cut the fruit bunches into several small bunches if they are too large, and lay a layer on the drying plate;

3. Soda soaking treatment: After the raw materials are soaked in soda treatment, immediately put them in clean water and rinse them clean. The drying time of the fruit after alkali maceration treatment can be shortened by 8 to 10 days;

4. Exposure: Put the grapes into the drying tray, expose them to the sun for about 10 days, when the surface is partially dry, you can turn them all over, and put them on the surface to continue to dry, until two-thirds of the fruits are dry, and dry them in the shade for a week.
