Grape juice is called vegetable milk. It has the following nutritional values:

Grape contains 16% carbohydrate (mostly glucose), 0.5% plant fiber, potassium chloride, iron and phosphorus, and digestible sugar. These substances contribute to the balance of blood acids and the construction of bones and nerves.



Among all summer fruits, grape has the highest iron content. They are good for anemia patients.

Grape juice can improve our immunity against diseases. As scientists have proved, every 100g grape contains 50 IU of vitamin A, 100 IU of vitamin C and 10 IU of vitamin B2.

Studies have shown that grape is beneficial to patients with nephritis because it can reduce albumin and sodium chloride in the kidneys.



Grape juice can improve liver function and promote bile secretion. Some doctors include grape juice in the diet of diabetes patients because it contains substances such as insulin.


Grape juice is extracted from grape pulp. It plays an important role in the wine industry, just like wine and brandy. But sometimes it is made into a non-alcoholic beverage.

Production technology of grape juice processing line

Grape juice is popular because of its nutritional value and good taste. Nowadays, grape juice production has become a very promising industry. In the process of grape juice production, the following aspects should be noted:

Protect the flavor, taste, color and characteristics of grapes as much as possible

Prevent pigment fading and tartar precipitation.

The extracted grape juice must be pasteurized to prevent yeast fermentation.

Prevent grape juice from coming into direct contact with iron, copper and other metals to prevent them from chemical reaction.

The grape juice production process includes raw material selection, cleaning, sorting, stemming, crushing, heating for color distillation, juice extraction, filtration, blending, clarification, filling and sealing, pasteurization and cooling.

Selection of raw materials for grape juice processing line

The grapes for making fruit juice should be fresh, mature and have good flavor. You should throw away those fruits that are not ripe, over ripe and mechanically damaged, or they will pollute the quality of the juice. It is best to process on the same day as the grapes are picked. If storage is required, please keep the temperature at 0 ºC and the humidity at 80% - 85%.



In order to improve the selection efficiency, experienced producers usually use grape vibration separators. It can transport grapes and separate unqualified grapes, stems and impurities through high-frequency vibration.





Grape cleaning of grape juice processing line

After selection, we need to clean the grapes with a fruit washing machine. The fruit surf cleaner can wash the grape surface and remove the dirt with rolling water without damaging the grape. To achieve a better cleaning effect, you can immerse the grapes in potassium permanganate solution for 3 minutes and then rinse them with tap water.

Grape stalking

Grape stem accounts for 3-8% of grape weight. They are mainly composed of lignin, with tannin content of 1-2.5%, acid content of 0.5-1.5%, and a small amount of bitter compounds. They must be removed from the grapes to prevent contamination of the grape juice.

Grape stalk remover is a kind of equipment specially used to remove grape stems and protect the integrity of grape grains. The press roller is made of non-toxic high elastic rubber, which will not damage the grapes. Then, the single screw pump will transport the grapes to the next process for juice extraction. The diameter of the roller screen can be customized according to the size of the grape.




Grape stalking machine of grape juice processing line

Adopt eccentric adjustable cutting edge. The rotation speed can be adjusted to adapt to different grape sizes. It improves the removal rate and particle integrity. The screen is made of nylon and has acid, alkali and corrosion resistance. For production capacity greater than 5t / h, wheel type separator shall be equipped.



Extraction of grape juice from grape juice processing line

After removing the stems, the grapes are extracted by a twin-screw grape crusher. It can press grapes into juice and separate peel and residue. Parts in contact with raw materials are made of SUS304 stainless steel. Lower extrusion speed was used to obtain higher juice yield. Pressure and humidity are adjustable. In addition, it is also suitable for fermented grapes and grapes with high fiber content.




Grape juice filtration of grape juice processing line

The crude grape juice contains some residues after extraction. You can filter it with a cloth bag and then collect the clear juice in a stainless steel tank.



Color extraction and heating of grape juice processing line

This is another process for making red grape juice. The purpose is to dissolve grape pigment in grape juice by heating crushed grapes to 60-70 ° C for 15 minutes.



Grape juice blending in grape juice processing line

The sugar content of grape juice was increased to 16% by adding 20% sugar solution. Then add 3 kg of 2% tartaric acid solution to every 100 kg of grape juice to prevent tartaric precipitation.

Preparation method of 2% metatartaric acid solution: add 1kg metatartaric acid to 49kg water. After soaking for 2 hours and boiling for 5 minutes, mix to promote dissolution, and filter with blue velvet. After that, add water to 50kg and cool it quickly for future use.



Clarification of grape juice in grape juice processing line

Gelatin and tannin are commonly used to clarify grape juice. Add 4-6 g of tannin per 100 kg of juice. After 8 hours, 6-10kg gelatin was added. Keep the temperature between 8 ºC and 12 ºC. When all the flocs in the juice are precipitated, use the bucket to suck out the clear liquid.


Pasteurization and filling of grape juice processing line

Pasteurization requires high temperature and short time. The grape juice was heated to 90 ° C for 30 seconds. Hot filling and aseptic cold filling are two common filling methods. During hot filling, when the grape juice is cooled to 85 ºC, it can be put into a can and sealed. In aseptic cold filling, the grape juice is cooled to room temperature and put into a bottle under aseptic conditions.
