Instructions for Operation Points
(1) Coconut cracking, water extraction, and shredding: After washing the mature coconut, split it along the middle to allow the coconut water to flow out. Collect the coconut water and filter it for later use. Split the coconut into two pieces, use a specially designed toothed scraper to scrape out the coconut flesh, making it loose. Then place it on a plate in a dryer, control the temperature at 70-80 ℃, and dry it into dried silk with a strong coconut aroma. Store it for later use.
(2) Grinding with water: After filtering tap water through a water purifier, it is heated to 70 ℃ by passing through a rapid water heater. 0.04% is added to a hot water tank and stirred. The coconut fiber and hot water are mixed evenly according to a weight ratio of 1:10 (coconut fiber: water), and then put into a grinding wheel for grinding. Coconut milk is separated by a 120 mesh sieve in a pulp residue separator, and then separated by a 180 mesh sieve in a second separator to obtain the first layer of juice. Coconut residue can be filtered with a small amount of hot water to obtain the second layer of juice. Mix the first and second juices and pump them into a storage tank for later use.
(3) Ingredients: Dissolve white sugar in a sandwich pot to make a concentrated syrup with a concentration of 50%. Filter it through a filter and set aside for later use. Open the discharge valve of the storage tank to let the coconut juice flow down to the batching tank. After the constant volume, add 10% of the filtered coconut water, then add citric acid flavoring solution to the pH value of 6~7, then add 18% concentrated syrup, 0.05%, 0.2% emulsifier (60% monoglyceride+10% sorbitan fatty acid ester+30% polyoxyethylene anhydride fatty acid ester), add an appropriate amount of stabilizer (xanthan gum), heat to 80 ℃, and then add a small amount of essence (or no).
(4) High pressure homogenization: two-stage homogenization, with a homogenization pressure of 23 megapascals for the first stage and 30 megapascals for the second stage, and a homogenization temperature of around 80 ℃.
(5) Sterilization: Sterilize at 121 ℃ for 15 minutes.

Key Machine of The Coconut Water and Milk Processing Line:
Coconut water extracting machine
It is composed of a coconut water drilling machine and a coconut water extraction conveyor, the machine is made of SUS304 material and with vat for coconut water collection. It is semi-automatic, one operator holds the coconut and aims the coconut eye to the drill to get the water then pours coconut water into the coconut water collection vat.
Coconut dehusking machine
Coconut dehusking machine is to remove the outer hard husk. This type of peeling machine is semi-automatic equipment. It is mainly composed of a round cutter plate, a hard alloy cutter head, a wedge blade knife and a geared motor. When the machine is working, manually hold the coconut, align the position of the front coconut eye with the sprout blade, and press it down. At this time, the rotating peeling blade and the wedge-shaped top blade squeeze the coconut placed in it, thus smoothly peeling the coconut meat. The whole machine is designed for fixed installation and height-adjustable placement, which can satisfy both large-scale production line use and individual independent use, and has a wide range of adaptability. The capacity is 200-300PCS/H.
Coconut paring machine
This coconut testa removing machine, which is also called coconut scalping machine or coconut paring machine, removes the thin and brownish testa off the deshelled coconut. This coconut testa removing machine requires one operator to feed the deshelled coconut flesh in pieces into the machine during the paring operation.
Coconut meat blanching machine
The crawler-type coconut meat blanching machine is composed of a stainless steel tank, a stainless steel baffle track, a steam heating interface, a cleaning port, a water outlet, a motor, a cooling sprinkler, a temperature control unit and other parts. The coconut meat is fed into the blanching tank. Driven by the crawler belt, the material is slowly moved towards the discharge port after being blanched and sterilized by high-temperature water. After the material discharge from the blanching tank, it is sprayed with cold water and transport to the sorting machine.
The whole machine is made of SUS304 stainless steel except for standard parts such as motors and bearings, which fully meet food hygiene requirements. The equipment is suitable for the pre-cooking process of coconut meat, vegetables and fruits, and has good temperature control. The processes of feeding, moisturizing, cooking, and discharging can be operated continuously without interruption. It has the advantages of low labor intensity, high performance, easy operation, and labor-saving.
Coconut meat sorting machine
We use belt conveyor to sort coconut meat and cut the coconut meat into small pieces.
Coconut meat grinding machine
The coconut meat grinding machine consists of a feeding hopper, a sawtooth type converter, a frame, the main shaft, a bearing housing, a transmission, and a discharge hopper. When the coconut meat enters from the feeding hopper, the coconut flesh is transferred to the sawtooth by a tangential spiral and grinds the coconut meat into small particles(3-5mm).
Coconut milk extracting machine
There are two types of machines for coconut milk extracting: one is using belt press, the other is using double screw juice extractors. To increase the coconut milk yield rate, usually, two stages of double screw juice extractors or double screw extractors and belt press combined extraction method are adopted. In the first stage of coconut milk extraction, the grinded coconut meat will be fed into the double screw extractors or belt press, after extraction, the coconut flake slag discharged from the first stage extractor will be blended with RO water (coconut meat slag and RO water ratio:1:1) and then fed into the second stage belt press or double screw extractor to get the coconut milk. Then the coconut milk from the first stage and second stage extractor will be mixed together.
The double screw type juice extractor usually has a higher yield rate than the belt press with about 55%-60%. The pneumatic double screw type extracting machine Working principle: Coconut kernel from the feed hopper led by screw. The cavity of the screw is smaller and smaller, press the coconut kernel, and coconut milk is pressed out and collected into a vessel, and the solid after extracted coconut milk is discharged out through the interspaces between the screw and pressure regulating head.
Coconut water disk separator
In a coconut water processing line, water is collected in tanks after the coconuts have been cracked. As this liquid contains oil and small particles like coconut meat, a separator is needed to separate and remove solids and to separate the oil from the water, preventing oxidation and discoloration. The separators are able to maintain the highest nutritional value and all the healthy properties of the water present inside the coconuts. And the water flavor profile is maintained without compromise. We provide a plug-and-play solution that fits perfectly into the processing line. Our separators are easy to install, operate, and maintain, with the high g-force ensuring extremely efficient separation.
Coconut water and milk cooling batch tanks
After we obtain milk and water from fresh coconuts, the liquids are fragile, we need to cool down to 4℃ instantly and store them into a closed environment using chill water. The cooling tank is for storing coconut water and milk at low temperatures for next station processing. The tank is made of SUS304/316 food-grade material with double layers insulation completed with inlet, outlet, man-hole, agitator, CIP washing ball etc.
Coconut water evaporator
As fresh coconut water is hard to preserve, so we usually process it into concentrate coconut water, then dilute with water (concentrated coconut water and water ratio are 1:10)to get the repack coconut water drinks. Fresh coconut water-soluble solid content is about 4brix, after vacuum falling film evaporator, concentrate coconut water made into 65brix. Coconut Water Concentrate has strong coconut taste, has medium sweet and yellow to orange color. The end products usually fill into 220kg aseptic bags in drums and storage into a cold dry environment.
Coconut water and milk pasteurizererilizer
There are two sterilizing processes during coconut water and milk processing. The first process uses plate-type pasteurizer to do pre-pasteurization (70-95℃ for 15-20 seconds)when extracting out the coconut water and milk, then storage into batch tanks instantly. the second process is that before coconut water and coconut milk filling, we use a tubular type UHT sterilizer(137-140℃ for 3-5 seconds) or DSI sterilizer to kill all the bacteria in the products. After sterilizing, the coconut water and milk can do aseptic filling into tetra pak cartons or hot filling into bottles or tin cans.
Coconut water and milk filler
According to different pasteurizationerilization and filling methods combination, there are mainly three filling methods for coconut water and coconut milk products.
Single-strength and RTD coconut water/coconut milk can do aseptic filling into aseptic brick cartons with UHT sterilization technology or hot filling into PET or glass bottles and small tin cans with pasteurization method;
Concentrated coconut water will be filled into aseptic bags in drums for repacking after UHT sterilizing or filled into bags after pasteurization for blast freezing.
Some manufacturers also make chilled or frozen coconut milk, this type of coconut milk after being pasteurized, will be cold-filled into containers then for cold distribution or frozen by blast freezer and for storage.
