A coconut processing plant is a complete industrial solution designed to process fresh coconuts into various coconut products, including coconut milk, coconut cream, coconut water, virgin coconut oil, and desiccated coconut.

Coconut is rich in fat and nutrients, making it an important raw material for the food and beverage industry. Coconut meat contains approximately 3.4%-4.0% protein and 30%-40% fat, while dried coconut meat contains 50%-70% coconut oil. In addition, coconut meat is rich in carbohydrates, dietary fiber, minerals, vitamins, and other essential nutrients. Coconut water is a natural refreshing beverage that contains approximately 0.1% protein, 0.1% fat, and 4% carbohydrates, along with minerals and electrolytes.

The coconut processing line includes a complete range of equipment for processing fresh coconuts into various coconut products. The main systems include a coconut dehusking and paring system, coconut water extraction system, coconut water filtration and pasteurization system, coconut meat cleaning and blanching system, coconut meat sorting system, coconut milk extraction system, coconut milk blending and sterilization system, coconut water evaporation system, coconut water and coconut milk filling system, CIP cleaning system, and RO water treatment system.

This coconut processing plant features high flexibility and can produce a wide range of coconut products by adjusting the process flow and equipment configuration, including UHT sterilized coconut milk and coconut cream, pasteurized chilled or frozen coconut water and coconut milk, single-strength coconut water, concentrated coconut water, virgin coconut oil (VCO), desiccated coconut, and coconut milk powder. According to customer requirements, different packaging solutions can be provided, including aseptic bags, tin cans, PET bottles, glass bottles, and other consumer packages.

The industrial coconut milk production process includes harvesting mature coconuts, removing the husk and shell, extracting and cleaning coconut meat, grinding, extracting coconut milk, blending with water and other ingredients, heating, separating impurities, homogenizing, pasteurizing or sterilizing, and finally filling the finished product into containers under hygienic conditions for storage and distribution.

The capacity of the coconut processing line ranges from 500 LPH to 50,000 LPH, and the equipment configuration can be customized according to the customer’s product requirements, production capacity, packaging type, and investment budget.

Single-strength coconut water production process: The single-strength coconut water is a natural, refreshing beverage rich in electrolytes, especially sodium and potassium, making it an ideal drink for hydration. For industrial production, fresh coconuts are dehusked and deshelled before coconut water extraction. The extracted coconut water is filtered by a cloth filter or disc centrifuge separator to remove impurities, then rapidly cooled, degassed, sterilized, and aseptically filled. Single-strength coconut water usually contains 92%-95% water with approximately 4°Brix soluble solids.

Concentrated coconut water production process: is produced by filtering and cooling fresh coconut water, followed by clarification and multi-effect vacuum evaporation to increase the concentration from about 4°Brix to 60-65°Brix. The concentrated product is commonly packed into 200 kg food-grade bags in drums for bulk transportation and long-term storage.

Coconut milk/cream production process: Coconut milk and coconut cream are natural oil-in-water emulsions extracted from mature coconut meat. Coconut milk generally contains 5%-20% fat, while coconut cream contains approximately 20%-35% fat. The industrial coconut milk/cream production process includes coconut dehusking, deshelling, paring, grinding, extraction, filtration, standardization, homogenization, sterilization or pasteurization, and aseptic filling. The final products can be packed in aseptic bags, Tetra Pak cartons, bottles, pouches, or cans.

Coconut milk powder production process: Coconut milk powder is produced by spray drying processed coconut milk. After extraction, filtration, standardization, pasteurization, and homogenization, the coconut milk is fed into a spray dryer to remove moisture and produce stable coconut milk powder. Anti-caking agents such as maltodextrin may be added to improve powder stability before final packaging.

Desiccated coconut production process: Desiccated coconut is a dried coconut product with approximately 2%-3% moisture content, widely used in bakery products, biscuits, cakes, cookies, and snacks. The production process includes grinding, hot air drying, screening, and packaging. Using a belt dryer, the drying temperature is generally controlled at 60℃-75℃, reducing coconut moisture from about 19% to 2%-3% before packaging.

Coconut oil production process: coconut oil is one of the major products extracted from coconut kernels. Depending on the raw material and processing technology, coconut oil production can be divided into two main methods: dry processing and fresh coconut processing:

–The dry process uses dried coconut meat (copra) as the raw material, where oil is extracted through pressing and then refined to produce RBD coconut oil (Refined, Bleached, and Deodorized coconut oil).

–The fresh coconut process uses fresh coconut kernels as the raw material and produces virgin coconut oil (VCO) through fresh-wet or fresh-dry extraction methods. VCO is obtained without extensive refining, helping to preserve the natural flavor, aroma, and nutritional properties of coconut oil.

The coconut water extraction system consists of a coconut water drilling machine and a coconut water collection conveyor. The equipment is made of SUS304 stainless steel and is equipped with a collection vat for hygienic coconut water storage.

The system is semi-automatic and requires one operator to place the coconut, align the coconut eye with the drilling device, extract the coconut water, and transfer it into the collection vat for further processing.

The coconut deshelling machine is used to remove the hard outer shell from coconuts. This semi-automatic machine is mainly composed of a circular cutter plate, hard alloy cutter head, wedge blade, and geared motor.

During operation, the operator manually places the coconut, aligns the coconut eye with the cutting blade, and presses the coconut downward. The rotating peeling blade and wedge-shaped blade work together to remove the hard shell and separate the coconut meat efficiently.

The machine features a fixed installation design with adjustable height, making it suitable for both large-scale coconut processing lines and standalone operation. It offers high adaptability and stable performance, with a processing capacity of 200-300 pieces per hour.

The coconut testa removing machine, also known as a coconut scalping machine or coconut paring machine, is used to remove the thin brown testa layer from deshelled coconut meat.

During operation, one operator manually feeds the deshelled coconut pieces into the machine, where the paring system removes the testa layer to obtain clean white coconut meat for further processing, such as coconut milk, coconut cream, and coconut powder production.

The crawler-type coconut meat blanching machine is used for blanching and sterilizing coconut meat before further processing. The machine consists of a SUS304 stainless steel tank, crawler conveyor, steam heating system, cleaning port, water outlet, motor, cooling spray system, and temperature control unit.

During operation, coconut meat is continuously fed into the blanching tank and slowly transported by the crawler belt. The coconut meat is blanched and sterilized in high-temperature water, then cooled by cold-water spraying after discharge before being transferred to the sorting system.

Except for standard components such as motors and bearings, the entire machine is made of SUS304 stainless steel, meeting food hygiene requirements. It provides precise temperature control and continuous operation, with advantages including low labor requirements, high efficiency, easy operation, and reliable performance. The equipment is also suitable for blanching vegetables and fruits.

The coconut meat sorting and cutting machine is an essential pre-processing unit in a coconut milk processing line. It uses a belt conveyor system to inspect, sort, and cut coconut meat into uniform small pieces before washing, grinding, and extraction.

The equipment helps ensure stable feeding to the coconut milk grinder, improve extraction efficiency and yield, reduce fiber blockage and mechanical loss, and provide consistent raw material quality for downstream processes, including pressing, separation, homogenization, sterilization, and aseptic or chilled filling.

The coconut meat grinding machine is used to grind coconut meat into small particles before coconut milk extraction. The machine consists of a feeding hopper, sawtooth grinding unit, frame, main shaft, bearing housing, transmission system, and discharge hopper.

During operation, coconut meat enters through the feeding hopper and is continuously transferred to the sawtooth grinding chamber by a tangential spiral mechanism. The high-speed rotating sawtooth cutter finely grinds the coconut meat into uniform particles of approximately 3-5 mm, improving the efficiency of subsequent coconut milk extraction.

The coconut milk extraction system mainly includes two types of extraction equipment: double screw juice extractors and belt presses. To improve coconut milk yield, industrial coconut processing plants usually adopt two-stage extraction, using either double screw extractors in both stages or a combination of double screw extractors and belt presses.

In the first extraction stage, ground coconut meat is fed into the double screw extractor or belt press to separate coconut milk from coconut residue. The coconut residue from the first stage is then mixed with RO water (typically at a 1:1 ratio) and processed through a second-stage extractor, such as a belt press, double screw extractor, or hydraulic press, to recover additional coconut milk. The coconut milk collected from both extraction stages is combined for further processing.

Double screw extractors can achieve approximately 55%-60% coconut milk extraction yield depending on coconut variety, maturity, and process conditions.

The working principle of the pneumatic double screw extractor is as follows: coconut meat enters through the feeding hopper and is conveyed forward by rotating screws. As the screw cavity gradually becomes smaller, the coconut meat is compressed, forcing coconut milk to separate and flow into the collection vessel. The extracted coconut residue is discharged through the gap between the screw and the pressure-regulating head.

The belt press coconut milk extractor is designed for high-capacity coconut milk processing plants. Before extraction, coconut meat is ground into fine flakes and then continuously fed into the belt press system.

During the extraction process, RO purified water is added to improve coconut milk recovery. The belt press applies continuous pressure to separate coconut milk from coconut residue, providing stable operation and high processing efficiency for industrial-scale production.

During coconut water extraction, coconut meat particles, fibers, colloidal substances, and protein compounds may enter the coconut water, resulting in turbidity, sedimentation, and flavor deterioration. Therefore, after preliminary filtration through a vibrating screen or 100-200 mesh filter, a disc centrifuge separator is commonly used for further clarification.

The disc separator removes fine suspended solids and improves the clarity and stability of coconut water. Depending on the process requirements, the separator can operate at high bowl speeds of approximately 5,000-8,000 rpm. Moderate heating (typically 40-60°C) can be applied to improve separation efficiency by reducing viscosity. The separator is capable of removing suspended particles in the range of approximately 5-50 μm, providing clarified coconut water suitable for subsequent degassing, pasteurization, concentration, or aseptic filling.

After coconut water and coconut milk are extracted from fresh coconuts, they are highly sensitive to microbial growth and quality deterioration. Therefore, rapid cooling to approximately 4℃ is required to maintain freshness, flavor, and product quality before further processing.

The coconut water and coconut milk cooling tank is designed for hygienic storage and temperature control of coconut liquids in a closed environment using chilled water circulation. The tank is manufactured from food-grade SUS304 or SUS316 stainless steel and features a double-layer insulated structure for efficient cooling performance.

The cooling tank is equipped with essential components, including product inlet and outlet ports, manhole, agitator, CIP spray ball, and other sanitary fittings, ensuring safe storage and easy cleaning during continuous coconut processing operations.

Fresh coconut water is highly perishable due to its rich nutrients and high water activity, making long-term storage difficult. Therefore, it is commonly processed into coconut water concentrate, which can later be reconstituted with water according to the required product specifications to produce coconut water beverages.

Fresh coconut water typically contains approximately 4°Brix soluble solids. Using a vacuum falling film evaporator, the coconut water is concentrated to around 60-65°Brix under low-temperature evaporation conditions. This process reduces thermal impact and helps preserve the natural coconut flavor and quality.

The resulting coconut water concentrate has a strong coconut aroma, moderate sweetness, and a light yellow to golden yellow color. It is commonly filled into 220 kg aseptic bags placed in drums and stored under suitable conditions for transportation and long-term storage.

During coconut water and coconut milk processing, heat treatment is applied at two stages to ensure product safety, quality, and shelf stability.

The first stage is pre-pasteurization after coconut water or coconut milk extraction. The fresh extracted product is quickly pasteurized using a plate heat exchanger, typically at around 75-95℃ for a short of seconds, to reduce the initial microbial load and prevent product deterioration. After pasteurization, the coconut water or coconut milk is rapidly cooled and transferred into hygienic storage tanks for temporary storage before further processing.

The second stage is final sterilization before filling. A tubular UHT sterilizer is commonly used to heat the product to approximately 137-140℃ for 3-5 seconds, effectively eliminating pathogenic microorganisms and achieving commercial sterility. For premium coconut water or coconut milk products, direct steam injection (DSI) sterilization technology can also be applied.

After sterilization, the coconut products can be filled using different packaging technologies according to market requirements, including aseptic filling into Tetra Pak cartons or aseptic bags, as well as hot filling into bottles, pouches, or tin cans.

The complete sterilization system ensures safe production while maintaining the natural flavor, color, and nutritional characteristics of coconut water and coconut milk.

According to different product types, sterilization methods, and market requirements, coconut water and coconut milk products can be filled using three main packaging solutions: aseptic filling, hot filling, and cold filling.

1. Aseptic Filling for Coconut Milk and Concentrated Coconut Water

Aseptic filling is widely used for coconut milk and concentrated coconut water products that require long shelf life and ambient storage. In B2B applications, sterilized coconut milk and coconut water concentrate are commonly filled into aseptic bags ranging from 5L to 220L for bulk transportation, industrial repacking, or further processing.

For B2C products, aseptic filling technology is commonly combined with UHT sterilization and used for packaging formats such as brick cartons, PET bottles, and other consumer packages, providing extended shelf life without refrigeration.

2. Hot Filling for Ready-to-Drink Coconut Water and Coconut Milk

Hot filling is mainly used for B2C ready-to-drink (RTD) coconut water and coconut milk products. After pasteurization, the products are filled at elevated temperatures into suitable consumer packages, such as PET bottles, glass bottles, and cans.

This filling method is suitable for products distributed through conventional retail channels and helps maintain product safety while preserving the natural flavor characteristics of coconut beverages.

3. Cold Filling for Frozen Coconut Water and Coconut Milk Products

Cold filling is mainly applied to chilled or frozen coconut water and coconut milk products. After pasteurization, the products are filled into hygienic containers under cold conditions and then stored through refrigeration or rapid freezing.

Frozen coconut water and coconut milk products are commonly used in foodservice, beverage preparation, and markets where cold-chain distribution is available.
