Grape Juice Processing Line

How to Make Grape Juice?

Grape juice is not only rich in glucose, minerals, and various vitamins, earning it the title "plant milk," but it is also the foundation for fine wine-making and healthy beverage production. The AGICO grape juice processing line covers the entire process from raw material selection to finished product filling. We not only provide individual machines but can also offer a one-stop turnkey project, including entire plant design, equipment manufacturing, installation and commissioning, and after-sales service based on customer needs. The AGICO grape juice processing line is suitable for juice processing plants, wineries, and beverage companies.

Core Equipment of Grape Juice Processing Line

Grape Vibrating Sorter

The AGICO Grape Vibrating Sorter utilizes advanced vibrating screening technology. Through high-frequency vibration and even material spreading, it effectively removes unripe, rotten grapes, as well as impurities like leaves, twigs, and stones mixed in. It completes the selection process without damaging the grape berries, ensuring a quality foundation for subsequent processing.

Grape Selecting

Fruit Surfing Washing Machine

Selected grapes enter the Fruit Surfing Washing Machine. This equipment uses tumbling water flow to gently scour the grape surface, thoroughly removing dust and residues while avoiding mechanical damage. It can be combined with a disinfectant solution soak, followed by a water spray rinse.

Grape Destemmer

Grape stems contain high levels of tannins and bitter compounds and must be removed. The AGICO Grape Destemmer utilizes eccentric, adjustable destemming blades. The rotation speed can be flexibly adjusted based on the grape variety, efficiently removing stems while maximizing berry integrity. The sieve drum is made from nylon or stainless steel, resistant to acids, alkalis, and corrosion, ensuring hygiene and safety. The crushing rollers are made from high-elasticity, non-toxic rubber, causing minimal damage to the pulp.

Double Screw Grape Crusher

Destemmed grapes are fed into the Double Screw Grape Crusher, the core equipment for juice extraction. This equipment uses a low-speed squeezing principle with adjustable pressure and gaps, efficiently separating juice from skins and seeds while ensuring juice clarity. All contact parts are made of SUS304 stainless steel. It is suitable not only for fresh grapes but also for fermented grape mash.

Subsequent Processing and Sterilization System

• Filtration and Clarification: Pressed juice contains pomace and requires fine filtration using plate-and-frame filters or diatomaceous earth filters. For products needing long-term stability, our process includes a gelatin-tannin clarification method, allowing sedimentation at 8-12°C to eventually obtain bright, clear juice.
• UHT Sterilizer: To preserve the fresh nutrients of the juice, we recommend using a plate UHT sterilizer for high-temperature short-time sterilization (e.g., 90°C for 30 seconds), followed by rapid cooling before filling.
• Aseptic Filling: Options include hot filling (85°C) or aseptic cold filling, ensuring the product is sealed under sterile conditions to extend shelf life.

Advantages of the AGICO Grape Fruit Juice Production Line

• Integrated Planning, Seamless Connection: From feeding and cleaning to filling, all equipment is designed and commissioned by us, ensuring capacity matching and stable operation.
• Superior Materials, Safe and Durable: All parts in contact with juice are made from food-grade stainless steel or polymer materials, eliminating heavy metal contamination.
• Customized Service: Whether for small workshops processing a few tons per day or large factories handling dozens of tons per hour, we provide tailored solutions. For example, for red grape juice, we can add jacketed heating equipment for the hot maceration stage.
• Practice-Proven Technology: Our process parameters (such as clarifying agent ratios, sterilization times) are based on extensive practical experience and scientific research, ensuring you can quickly produce high-quality products after commissioning.
