Juice Production
Juice production involves extracting and processing liquids from fruits and vegetables to create high-quality, flavorful beverages. Huading provides advanced centrifuges tailored for the juice industry, ensuring efficient separation and clarification processes.
Fruit juice products hold a significant share in the beverage industry, reflecting their widespread popularity. Juices made from high-quality fruits and vegetables are not only delicious but also rich in vitamins and minerals beneficial to human health.​
Industrial juice production is a complex process that presents various challenges. One of the primary obstacles is producing high-quality final products that meet the stringent demands of end consumers. Additionally, juice production requires substantial energy consumption, posing economic and financial challenges for manufacturers.​
To achieve efficient operations with high economic benefits, companies need to establish continuous production processes. This necessitates the use of industrial juice production equipment that is easy to clean and maintain, ensuring consistent product quality and operational efficiency.
Typical Processing Flow for Fruit and Vegetable Juices
- Fruits or vegetables are conveyed to a grinder via a conveyor belt for milling.
- The conveyor belt is rinsed with water, which separates the ground fruit or vegetable pulp into a mixture of liquid juice and solid pulp.
- The solid-liquid mixture is then sent to a vibrating screen for separation, with the liquid phase being directed for enzymatic treatment.
- After enzymatic treatment, the liquid phase is sent to a centrifuge for further separation, resulting in the final fruit or vegetable juice.
Centrifugal Separation in Juice Processing
The juicing process starts by selecting, washing, and cutting fresh, ripe fruits. Various methods, including manual or mechanical pressing, are then employed to extract juice from the produce. The extracted liquid is then subjected to centrifugal filtration and separation to effectively remove solid residues. Centrifuges are widely used in both the vegetable and fruit juice industries, and today, production would not be possible without them.
1. Clarification
After extraction using presses and decanters, fruit juices may remain cloudy. To prevent any negative impact on the juice quality, it is essential to promptly remove the particles causing the turbidity. Centrifugal clarifying separators are particularly effective for pre-clarifying juices and ensuring a clean, high-quality product.
2. Direct Juice De-oiling
Freshly pressed juice often contains unwanted peel oil, which can give the juice a bitter taste. This oil can be efficiently removed with specialized separators, improving the juice’s flavor and overall quality.
3. Essential Oil Production
Citrus peel contains valuable essential oils, which can be separated from the peel using water washing and then further separated into distinct components (water and essential oil) via a two-stage centrifugal system.
4. Wax Removal
During essential oil production, excess wax may be present in the oil phase. Special separators can be used in a process called “winterisation” to remove these waxes, resulting in a purer and higher-quality essential oil.
5. Pectin Production
Decanter centrifuges can separate coarse extracts made from fresh fruit skins and pulp. These extracts are then further clarified by using a separator, improving the purity and yield of pectin. Decanters can also be applied in subsequent sedimentation processes for more refined extraction.
6. Residue Handling
Ultrafiltration is often used for fine clarification, but this process generates a retentate with high solid content. Decanter separators can concentrate this residue, enabling the recovery of valuable juice. Additionally, specialized separators can extend the cleaning intervals of ultrafiltration systems and enhance overall efficiency.
