We can discuss in detail the raw materials and products of the grape juice production line from the following aspects:
1. Raw materials
•
Fresh grapes: This is the main raw material for producing grape juice. Choosing fresh, ripe, and pest free grapes is crucial to ensure the taste and nutritional value of the final product.
•
Water: Used for cleaning grapes and diluting concentrated grape juice.
•
Sugar: Adjust the sweetness of grape juice as needed.
•
Vitamin C: Sometimes added to enhance the nutritional value of grape juice.
•
Preservatives: Optional, used to extend the shelf life of products.
2. Product
•
Freshly squeezed grape juice: directly extracted from fresh grapes, retaining the most nutrients.
•
Concentrated grape juice: made by evaporating some of the water, convenient for transportation and storage.
•
Resveraging grape juice: Made from concentrated grape juice and water, it is convenient for large-scale production and distribution.
•
NFC (Not From Concentrate) Grape Juice: Non concentrated reduced grape juice, extracted directly from fresh grapes without concentration treatment, with a taste closer to freshly squeezed grape juice.
•
Functional grape juice: Specific nutrients such as vitamins, minerals, etc. can be added to meet the needs of different consumers.

Some advantages of grape juice processing line:
1. The equipment has simple operation, powerful machine performance and low energy consumption.
2. It is a convenient device, which can identify unqualified grapes, immature grapes, bad grapes and hidden impurities in grapes.
3. Remove the residual gravel, sand, stems and raw grape grains in the grape cluster.

Technological process of grape juice processing line:
First, the grape grains are sent to the vibrating screen to remove the impurities hidden in unqualified grapes, immature grapes, bad grapes and grape grains. Then, the grape seeds are evenly sent to the stemming machine through the elevator to completely remove the stems, which will not cause damage to the grape fruit. Then, the grape granules are peeled and seeded, and the grape pulp is beaten, sterilized and filled.
We manufacture all the equipment needed for grape juice production; From raw grape unloading system to grape juice extraction system, from grape juice ultrafiltration system to grape juice evaporator system, grape juice pasteurizer, grape juice clarification system, grape juice degumming tank and grape juice processing tank to grape juice storage tank.
