Grape Juice Production Line Overview
Our grape juice production line is designed for businesses looking to extract high-quality juice from grapes efficiently and consistently. Grape juice plays an important role in the wine industry, including wine and brandy production. It can also be made into non-alcoholic beverages. With over 15 years of experience in food machinery manufacturing, Joyshine Machinery provides complete turnkey solutions ranging from small-scale operations to large industrial facilities. The entire line is constructed with food-grade SUS 304 stainless steel, ensuring durability, hygiene, and compliance with international food safety standards.
The complete grape juice production process includes: raw material selection, cleaning, sorting, stem removing, crushing, heating for color distilling, juice extracting, filtration, blending, clarification, filling and sealing, pasteurization and cooling. In the production process, it is essential to protect the flavor, taste, color and properties of grapes as much as possible; prevent the fade of pigment and the precipitation of tartars; pasteurize the extracted juice to prevent yeast fermentation; and prevent grape juice from direct contact with iron, copper and other metals to avoid chemical reactions.

Main Machines in the Line
Each machine is optimized for high performance and easy integration
Grape Vibration Separator
High-frequency vibration separates unqualified grapes, stems and impurities, improving selection efficiency. The adjustable vibration amplitude and frequency adapt to different grape varieties and sizes.
- Capacity: 1-10 tons/h
- Vibration frequency: 960-1450 rpm
- Material: SUS 304
- Power: 0.37-1.5 kW
Fruit Surfing Cleaning Machine
Air bubble and spray washing system thoroughly cleans grapes, removing dirt without damaging the fruit. The surfing water flow creates gentle friction to scrub the grape surface clean.
- Capacity: 1-10 tons/h
- Water consumption: 2-8 m³/h
- Material: SUS 304
- Power: 2.2-5.5 kW
Grape Destemmer
Specialized equipment with adjustable destem blade and customizable drum sieve. The crushing roller is made of non-toxic, high-elastic rubber that protects grape grain integrity. A single-screw pump transmits grapes to the next process.
- Capacity: 1-50 tons/day
- Destem blade: Eccentric & adjustable
- Drum sieve: Customizable pore size
- Power: 1.5-7.5 kW
Double-Screw Grape Crusher
Low-speed squeezing achieves high juice yield (75-85%). All contacting parts with raw materials are made of SUS 304 stainless steel. The pressure and humidity are adjustable. Also applies to fermentative grapes and high-fiber contents.
- Capacity: 1-50 tons/day
- Juice yield: 75-85%
- Screw speed: 5-15 rpm
- Power: 3-15 kW
Color Distillation Tank
Heats crushed grapes to 60-70°C for 15 minutes to dissolve pigments for red grape juice production. This optional step is essential for producing vibrant, richly-colored red grape juice with full-bodied flavor.
- Heating temp: 60-70°C
- Holding time: 15 min
- Heating method: Steam / Electric
- Material: SUS 304
Blending Tank
Precision sugar and acid adjustment to achieve target Brix (16°) and pH. Stainless steel tank with agitator ensures uniform mixing. Add 20% sugar liquor and tartaric acid solution to prevent tartar precipitation.
- Volume: 500-5000 L
- Agitator speed: 20-60 rpm
- Heating: Optional jacket
- Material: SUS 304
Clarification Tank
Gelatin and tannin clarification at 8-12°C. Add 4-6g tannin per 100kg juice, wait 8 hours, then add 6-10kg gelatin. When all floccules settle, the clear juice is extracted from the top.
- Temperature: 8-12°C
- Clarification time: 8-12 hours
- Volume: 500-5000 L
- Material: SUS 304
Plate UHT Sterilizer
High-temperature short-time pasteurization at 90°C for 30 seconds. The plate heat exchanger ensures rapid heating and cooling, preserving the natural flavor, color and nutrients of the grape juice while ensuring food safety.
- Temperature: 90°C
- Holding time: 30 seconds
- Plate material: SUS 316
- Capacity: 1-50 tons/day
Filling & Sealing Machine
Hot filling at 85°C or aseptic cold filling options available. Supports bottles, cans and pouches. The precise filling volume control and automatic sealing ensure product integrity and extended shelf life.
- Filling temp: 85°C (hot) / RT (cold)
- Package types: Bottle, Can, Pouch
- Precision: ±1%
- Material: SUS 304
Cooling System
Rapid cooling after pasteurization to preserve nutrients and flavor. Spray cooling or immersion cooling options available. Brings the product temperature down to room temperature quickly for safe handling and storage.
- Cooling method: Spray / Immersion
- Target temp: Room temperature
- Cooling time: 10-30 min
- Material: SUS 304
