You might have often wondered how does juice production line work. The process of fruit juice production starts by purchasing raw materials. The fruit is selected based on quality before it is dumped or unloaded into the juice production line. There are two methods of unloading: one is called the wet method or hydro-unloading and the other is known as the dry method.


The fruits are washed two or three times before they are transported to the sorting unit. The sorting unit is an important section of the juice production line. The sorting machine selects the best fruit from the abundance of raw material that is supplied to it. The criteria of selecting a high quality fruit is to test its nutrition value, freshness, juiciness and sugar to acid ratio. Trained employees carry out the fruit inspection and reject any raw material that does not fit the quality benchmark. The common sorting machine used in the juice production line is the rolling rail.


Along with sorting, the fruit is given a good brush and spray cleaning to get rid of extraneous substance and any stickiness on the peel. The rotatory brush rollers do the job of giving the fruit a good clean and removing all the dirt. The fruit surfing machine gives the fruit another clean by using a blower and transfers the fruit into an elevator. The elevator is also known as the vertical screw feeder. The fruit then goes into a peeling and extraction machine where the fruit is peeled and pulp is extracted from it. The fruit pulp is pumped into tanks and taken to the next stage of juice production line.

The pulp is pressed to extract maximum juice from the fruit. The chamber in which pulp is pressed is fully automatic and pressurized to achieve optimum results. There is a piston inside the chamber that squeezes juice out of the fruit pulp. The process continues for several cycles and the cylinder continuously rotates to loosen more pulp for pressing.


The extracted juice is transferred to a storage site. The storage site has a closed system to guarantee hygiene of the pressed juice. The unclarified juice is then taken into intermediate tanks where pasteurization takes place and aroma of the fruit is restored which was lost in the evaporation process. Pasteurization normally takes place between 95 to 105°C and kills all the microbes that might have survived.


The unclarified juice is then taken into the ultrafiltration system where it goes through the evaporation process again and is cooled to low temperatures of 5-8°C through condensation. Samples from the clarified juice are tested in the laboratory before the content is transported into juice filling machines. The juice filling machine manufactures juice bottles in different packaging and quantities. Each bottle is labelled according to brand and shipped to a warehouse from where it is taken into retail shops. The juice filling machines are technically advanced computerized equipment that provide monitoring and control over the entire filling process, and make the operation run smoothly.
