c, bottle filling packaging part includes water treatment system, bottle blow molding machine, juice bottle filling machine, bottle Reverse cap sterilizer, bottle cooling pasteurisation tunnel, film or carton packing machine.
Here’s an English explanation of the roles of each machine in a juice processing line, organized by workflow:
1. Syrup Melting Tank
Function: Dissolves sugar, concentrates, or additives into syrup under controlled heating. Ensures uniform consistency for blending with juice base.
2. Juice Mixing Tanks (2 units)
Function:
Tank 1: Blends syrup, fruit juice concentrate, water, and stabilizers (e.g., pectin) to achieve the target Brix level and flavor profile.
Tank 2: Adjusts acidity (pH) and adds preservatives or vitamins (if required) while maintaining agitation for homogeneity.
3. Double Filter
Function: A two-stage filtration system:
Pre-filter: Removes coarse particles (e.g., pulp fragments, undissolved solids).
Fine filter: Eliminates micron-level impurities (e.g., colloids, microorganisms) using membrane or diatomaceous earth filtration.
4. Homogenizer
Function: Breaks down fat globules and suspends solids evenly in the juice under high pressure (15–25 MPa). Prevents sedimentation and enhances mouthfeel stability.
5. Vacuum Degasser
Function: Removes dissolved oxygen and entrapped air from the juice under vacuum conditions. Benefits:
Prevents oxidation (color/flavor degradation).
Extends shelf life.
Improves UHT sterilization efficiency.
6. UHT Juice Sterilizer (Ultra High Temperature Sterilizer)
Function: Heats juice to 135–150°C for 2–6 seconds to kill microbes (e.g., bacteria, yeasts) while minimizing nutrient loss. Critical for aseptic packaging compatibility.
7. Aseptic Tank
Function: Stores sterilized juice temporarily in a sterile, temperature-controlled environment (4–25°C) before filling into pre-sterilized containers (e.g., cartons, PET bottles).
8. CIP System (Clean-in-Place System)
Function: Automatically cleans and sanitizes tanks, pipes, and equipment using hot water, detergents, and disinfectants without disassembly. Ensures hygiene and prevents cross-contamination between batches.

There are various ways to make juice, and we can produce different types of juice according to the requirements of customers.
1. NFC juice is the abbreviation of the English phrase “Not From Concentrate”, and it is called “non-concentrated 100% pure juice” in Chinese. It is made by washing fresh original fruits, squeezing out the juice, and directly filling it into containers after instant sterilization (without going through the processes of concentration and restoration). Since this freshly squeezed juice is exposed to heat for a relatively short time during the processing, the loss of nutrients is relatively small, and it can better retain the original flavor of fresh fruits. The filling of NFC juice can be divided into cold filling and hot filling. Cold filling is more conducive to preserving the nutritional components and flavor of the original juice, while hot filling is more conducive to the preservation time of the juice. The disadvantages of this kind of juice are that it is suitable for low-temperature storage and has a relatively short shelf life. In addition, since it is a real pure juice and is not easy to store, the cost is also relatively high. NFC juice is made by directly pasteurizing the fruit juice squeezed from fruits and processing it in a low-temperature environment.
2. Fruit juice beverages are prepared by adding water, white sugar, food additives, etc. on the basis of fruit juice or concentrated fruit juice. Most of the fruit juice beverages commonly seen on the market are restored from concentrated fruit juice, commonly known as FC concentrated fruit juice. There is a serious loss of nutrients. The advantage of restored fruit juice is that it is easy to store and the price is relatively low, which is generally acceptable to the public. Due to the complex processing of concentration and restoration, its freshness and taste cannot be compared with those of NFC products. The ingredient list shows “water”, “concentrated fruit juice”, etc., and this kind of juice actually belongs to “restored fruit juice”.
a. Preparation of 100% fruit juice: 100% FC (From Concentrate), that is, 100% concentrated fruit juice, is made by first squeezing the fruit into original juice and then using the method of low-temperature vacuum concentration to evaporate a part of the water. When preparing 100% fruit juice, the same amount of water that the fruit juice lost during the concentration process needs to be restored to the concentrated fruit juice raw material to make a product with the color, flavor and soluble solid content of the original fruit pulp.
b. Preparation of non-100% fruit juice: Non-100% concentrated and restored fruit juice is made by diluting concentrated fruit juice with water, sugar, preservatives, citric acid and other flavoring agents to restore it into drinkable juice.
3. Fruit-flavored beverages: This kind of beverage only has the taste of fruit juice but contains no fruit juice. It is mixed and prepared with sugar and/or sweeteners, acidity regulators, edible flavors, etc. Some beverage outer packages will indicate “apple flavor”, “orange flavor”, etc. The taste of these beverages is average, and they are all prepared by adding corresponding flavors. This kind of beverage has a high sugar content and contains a large amount of artificial synthetic pigments, so it is advisable to drink it as little as possible.
Water Treatment:
Classification: The water treatment equipment encompasses a diverse range, including reverse osmosis water treatment machines, ultrafiltration water treatment systems, bipolar reverse osmosis units, reverse osmosis systems integrated with EDI electrolysis devices, reverse osmosis setups equipped with electrolysis components for the production of weakly alkaline water, and seawater desalination water treatment facilities. In a typical bottled water filling production line, it is common practice to install a reverse osmosis water treatment machine.
Working Principle of Reverse Osmosis Water Treatment: This machine operates by applying high pressure to push water through a semi-permeable membrane. Through this process, it effectively eliminates dissolved salts, organic substances, bacteria, viruses, and other contaminants present in the water, ultimately yielding high-purity water.
Components: The system consists of a raw water storage tank, a quartz sand filtration device, an activated carbon filtration apparatus, a water softening filter unit, a precision filter, a reverse osmosis membrane module, an ultraviolet sterilization device, an ozone generator, an ozone mixing tower, and a pure water storage tank.
Output: Our water treatment machines offer a wide spectrum of output capacities. These include 250 liters per hour, 500 liters per hour, 1000 liters per hour, 2000 liters per hour, 3000 liters per hour, 5000 liters per hour, 8000 liters per hour, 10 tons per hour, 20 tons per hour, 30 tons per hour, 50 tons per hour, and 100 tons per hour.

High temperature resistant bottle blowing machine:
The filling machine paired with the juice production line is often a high-temperature resistant bottle blowing machine, because the filling temperature of juice is 80-90 degrees, and high-temperature resistant bottle blowing machines are 60-80% more expensive than ordinary bottle blowing machines. Not only are bottle blowing machines more expensive, but the preforms and caps used to produce bottles are also more expensive, and the materials used for preforms and caps are more resistant to high temperatures. The preform used to produce this type of bottle weighs more, and the blown bottle structure will have many muscle lines and small protrusions on the surface, which can increase the stability of the structure.
If you don’t want an expensive high-temperature bottle blowing machine, another solution is to sterilize the juice through an ultra-high temperature instantaneous sterilization machine at 115 degrees Celsius, then cool the juice to around 60-70 degrees Celsius before filling. This way, ordinary bottles can be used, and you don’t need a high-temperature bottle blowing machine anymore. However, the shelf life of juice filled at 60-70 degrees Celsius is not as long as that filled at 80-90 degrees Celsius.

Labeling Machines:
Classification: There exist four types of labeling machines, namely self – adhesive label labeling machines, sleeve label labeling machines, hot – melt adhesive OPP label labeling machines, and cold – glue paper label labeling machines. We only supply the machines. Customers are required to purchase labels on their own, while we can also assist customers in purchasing labels on their behalf.
Different bottle shapes and sizes might necessitate the use of different types of labeling machines. The way labels are applied to the bottles also leads to variations in machines. For example, there are single – sided round bottle labeling, single – sided double – sided labeling, single – sided triple – sided labeling, double – label front – and – back double – sided labeling, and applying three labels to one bottle, etc.
Labeling machines are usually used in conjunction with coding machines. Coding machines can print the production date on the bottles. The labeling machine is connected to the filling machine and the film wrapping machine via a conveyor belt. We can recommend suitable models to customers according to the production line speed, bottle shape, and label size.
The label content is designed and provided by the printing company.

Film Wrapping Machine:
Working Principle: The film wrapping machine consists of a conveying section, a bottle – separating section, a film – cutting section, and a shrink tunnel. The conveying section of the film wrapping machine is relatively wide and docks with the conveyor belt of the production line. There are bottle – separating plates on the conveyor belt. When the bottle – grouping device is activated, it divides the bottles into groups and sends them into the film – wrapping section. Once a group of bottles is wrapped by the film – wrapping section, it immediately enters the shrink tunnel. The shrink tunnel operates by motor – heating, which tightly shrinks the film onto a group of bottles, thus turning the loose bottles into a package for easy transportation. A palletizer and a stretch – wrapping machine can be connected to the rear end of the film wrapping machine.
The width of the film is designed according to the size of a group of bottles required by the customer. The conveyance of a group of bottles can be in any form, with the most common being 3×4 = 12 bottles and 4×6 = 24 bottles.
Classification: There are transparent film wrapping machines, colored – film wrapping machines (with printed patterns on the film), film wrapping machines with bottom trays, etc. Different production speeds result in different models of film wrapping machines.
The consumable of the film wrapping machine is PE film, and the vulnerable part is the heating tube in the shrink tunnel.
