A litchi processing line is a facility designed for processing litchi fruit into various products such as juice, pulp, syrup, or canned litchis. Similar to other fruit processing lines, it consists of several stages and equipment to efficiently convert the raw fruit into marketable products.

Here are the main steps involved in a litchi processing line:

1. Receiving and sorting: Freshly harvested litchi fruits are received at the plant and sorted to remove any damaged or overripe fruits. This is typically done manually or using sorting machines.

2. Cleaning and washing: The litchis undergo a thorough cleaning and washing process to remove dirt, debris, and any pesticide residues. This helps ensure the safety and purity of the final product.

3. Peeling and deseeding: Depending on the desired product, the litchis may be peeled and deseeded. This can be done manually or using specialized machinery.

4. Crushing and pulping: The peeled and deseeded litchis are crushed or pulped to extract the juice and pulp from the fruit. This can be achieved through processes like maceration, pulping machines, or enzymatic treatment.

5. Juice extraction: The crushed litchis undergo a process to separate the juice from the solids. This can be done using methods such as pressing, centrifugation, or filtration.

6. Heating and pasteurization: The extracted litchi juice is heat-treated to eliminate any harmful bacteria or microorganisms and to extend the shelf life of the product. This step is crucial for ensuring food safety.

7. Clarification and filtration: The litchi juice is clarified and filtered to remove any remaining impurities or particles, resulting in a clear and smooth final product.

8. Formulation and packaging: Depending on the desired product, the litchi juice or pulp may be blended with other ingredients such as water, sweeteners, or flavorings. The final product is then packaged into bottles, cans, or Tetra Pak containers.

9. Quality control and storage: The finished products go through quality control checks to ensure they meet safety and quality standards. They are then stored in suitable conditions until distribution.

Throughout the processing line, various equipment such as conveyors, washers, peelers, pulpers, pasteurizers, and packaging machines are used to facilitate the different processing steps.

It's worth noting that the specific setup of a litchi processing line may vary depending on the scale of operation, desired product range, and other factors.

Major equipment
Litchi shelling machine is applicable to the pre-treatment of litchi wine and litchi drinks. Only litchi after shelling can be put into production. The main function of the equipment is to remove the stem, clean and disinfect the litchi. After the treatment of the equipment, the peel and pulp of litchi can be separated.

The litchi peeler and corer is designed by absorbing foreign advanced technology. First, the litchi is cut with a blade and peeled and cored by the strike force of the high-speed L-bar. This equipment is characterized by no classification and high efficiency. It is suitable for large-scale industrial production. Peeler and corer are carried out at the same time, reducing the operation process.

Litchi processing line is widely used in litchi juice industry, fruit wine industry, quick-frozen pulp, quick-frozen pulp, etc.
Litchi processing production lines were successfully exported to Madagascar, India, Thailand, Vietnam and other countries in 2016.
The specifications of litchi processing production line are: 2-3t/h, 4-5t/h, 5-10t/h, etc.

Litchi processing plant is suitable for processing litchi and longan. It can clean and peel litchi, remove litchi seeds, extract litchi juice and litchi pulp. Litchi juice and pulp can be further processed into litchi juice, pulp and wine.

Roller Fruit Sorter of litchi processing production line

This machine is used for sorting spherical and oval fruits such as litchi, pineapple, pomegranate, mango, citrus, apple and pear. Driven by the motor and chain, the roller rotates, and the fruit rotates and moves forward at the same time. In this process, employees can select defective fruits.



Brush spray fruit washing machine for litchi processing production line

The brush can remove dirt and pesticide residues on the peel, and the spray can wash away all impurities. This machine is suitable for litchi, apple, pear, orange, tomato and carrot. It can be combined with other fruit washing machines to achieve a thorough cleaning effect.



Surfing fruit washing machine for litchi processing production line

This machine is suitable for cleaning spherical and oval fruits. The high-pressure water pump keeps the fruit rotating in the tank. The clean fruit is transferred to the fruit elevator through the impactor, and the dust and impurities will flow into the receiving tank at the bottom. The surf fruit washing machine can be equipped with ultrasonic and ozone systems to achieve sterilization effect.



Scraper fruit elevator of litchi processing production line

This is the transmission equipment of litchi processing plant. It is used to transfer fruit from one process to the next. It is composed of drive motor, sprocket and disk, scraper, rack and tensioning device. When starting work, the motor drives the chain plate and carries the scraper. The fruit is fed to the scarifier and lifted to the next equipment.



Litchi / longan peeling machine for litchi processing production line

This machine is used for pretreatment of litchi / longan juice and wine. Using rubber roller to separate litchi pulp and shell, the peeling rate is as high as 99%. Use after litchi and longan are blocked, cleaned and disinfected.



Litchi / longan corer for litchi processing production line

This machine can cut litchi and longan, extrude the pulp, separate the core and peel, and transport the pulp to the next process.



Fruit pulper of litchi processing production line

This machine is used for crushing pulp, extracting juice and separating residue. It integrates crushing and centrifugal functions. The process is carried out in a closed state to minimize oxidation and maintain the flavor of the juice. The solid content in the juice and the humidity of the slag can be adjusted.



Characteristics of litchi processing production line

Litchi processing plant can automatically realize the cleaning, sterilization, peeling, nucleation, pulping and juicing of litchi or longan. It is widely used in the pretreatment of litchi, longan juice and wine.


The processing plant is specially designed to adapt to the characteristics of litchi and achieve high efficiency. We can customize the specifications according to the needs of customers.
