Coconut Oil & Milk Processing Plants

A coconut oil and milk plant turns husked nuts into coconut milk, cream, virgin oil or copra-based oil, and the route, wet from fresh kernel or dry through copra, is the first decision.

Coconut Oil & Milk Processing Plants

Dehusking and shelling are upstream of this line. The two routes share almost no equipment after the husk is removed, so a buyer should settle the route before anything is sized: dry copra drying, milling and pressing for crude oil, or grating and milk pressing for milk, cream and wet-process virgin oil. Next come the product and pack, whether oil is sold crude, virgin or refined, how steady the nut supply is through the year, and where the shell, husk, cake and parings will go. Heat treatment of milk and the drying of copra are the two steps that most often decide whether a plant works well. Capacity is stated in nuts per day, so the number of operating hours and the share of nuts going to oil or milk should be given early.

In the dry route the nut is split and the kernel dried to copra, then ground, flaked and cooked before an expeller press takes out the oil. The cake that remains still holds some oil and is sold as feed, or solvent extracted if a lower-oil meal is wanted. Pressed oil is crude oil. Refined, bleached and deodorised oil is made from it by neutralising, bleaching and steam deodorising, and is only needed if the product specification calls for it. In the wet route no drying takes place. Fresh kernel is grated and pressed to give a milk, and virgin oil is separated from that emulsion by chilling and centrifugation or by fermentation. Oil from the wet route holds up well when the time and temperature between grating and separation are kept short and the handling afterwards is closed. A milk line goes a different way: the milk is homogenised, heat treated and filled. Coconut milk proteins are poor emulsifiers and heat sensitive, and cream fouls heat exchangers, so homogenisation, the heating profile and any stabiliser are designed as one system with the cleaning cycle. Shell and husk can fire the copra dryer.

Typical Process Route

1

Receiving and preparing nuts

Nuts are checked on arrival, then dehusked and shelled upstream of this line. The days between harvest and processing affect the quality of kernel, so nut age and storage matter as much as the machines.

2

Paring and washing the kernel

The brown skin is pared off where white kernel is needed for milk or virgin oil, and the kernel is washed. Parings are a separate stream that some plants extract for oil.

3

Drying copra (dry route)

Split kernel is dried evenly and soon after splitting, by hot air or other heat, to a moisture low enough to keep. Slow drying, wet weather and early splitting raise the risk of mould, so a plant that buys copra should check moisture and mould at the gate.

4

Grating and milk pressing (wet route and milk)

Fresh kernel is grated and pressed to give milk, which is the starting point for both milk products and wet-process virgin oil. Grated meat oxidises quickly, so it should not stand before pressing.

5

Milling and pressing copra

Dried copra is ground, flaked and cooked to a low moisture, then pressed in an expeller. The cake leaves with some oil still in it, which affects both oil recovery and the value of the meal.

6

Separating oil from the milk

In the wet route, oil is separated from the milk emulsion by chilling and centrifuging, or by fermentation. The time and temperature between grating and separation set how oxidised the finished oil is.

7

Settling and filtration

Pressed or separated oil is settled and filtered to remove fine solids and moisture. Oil is then stored in clean, closed tanks, away from air, light and heat.

8

Refining where specified

Crude oil is neutralised, bleached and deodorised only if a refined product is required. Virgin oil and crude oil skip this section.

9

Heat treatment and filling of milk

Milk is homogenised, heat treated and filled. This is the hardest step on the milk side because the emulsion tends to separate on heating and cream coats heat-exchange surfaces.

Plant Output

Virgin or crude coconut oilRefined coconut oil, where specifiedCoconut milk and creamCopra cake or meal for feedShell and husk for fuel or charcoal

Applications

  • Virgin coconut oil for food, cosmetic and wellness products
  • Crude coconut oil for sale to refiners
  • Refined coconut oil for cooking and food manufacture
  • Coconut milk for cooking and beverage use
  • Coconut cream for sauces, desserts and confectionery
  • Copra cake and meal as animal feed
  • Oil for soap and personal-care manufacture
  • Shell and husk as fuel for the dryer, or as charcoal

Key Features

  • Route Chosen First

    Dry copra and wet fresh-kernel routes use different dryers, presses and separators. Design the plant around one route, or two clearly separate sections, not a loose mixture of both.

  • Copra Moisture Control

    Even drying soon after splitting and a moisture check on incoming copra protect the oil from mould and from a poor flavour.

  • Cream-Safe Heat Exchange

    Coconut cream fouls heat-exchange surfaces and milk tends to separate on heating, so the homogeniser, the heater and the cleaning cycle are designed together.

  • Closed Handling of Oil

    Short, cool, closed handling between grating, separation and storage keeps the oxidation of the finished oil low.

  • By-Product Handling

    Shell, husk, cake and parings leave in larger amounts than the oil. Fuel use, feed sale and storage need a place on the site plan.

  • Refining as a Separate Section

    A refinery is added only when the specification calls for refined oil, so a crude or virgin oil plant does not carry its cost.

Frequently Asked Questions

What information is needed to size Coconut Oil & Milk Processing Plants?
The number of nuts per day and the hours the plant will run, the product mix of oil, milk and cream, whether the route is fresh kernel or copra, and whether oil is sold crude, virgin or refined. For milk, give the pack type and shelf life. Also describe the nut supply across the year and where the shell, husk and cake will go.
What capacity range does Coconut Oil & Milk Processing Plants cover?
The indicative capacity range is 0.5–10 tonnes coconuts/day. It is stated on a coconuts basis per day, so restate your own volume on that basis and say how many hours a day the plant will run.
Can the same line make both virgin coconut oil and coconut milk?
They share the front end. Both start from fresh kernel that is grated and pressed to give a milk, and in the wet route that milk is the intermediate from which virgin oil is separated by chilling and centrifugation or fermentation. They then diverge: milk is homogenised, heat treated and filled, while oil is de-emulsified, filtered and stored. Copra-based oil uses a different, dry front end altogether, so the choice of route matters more than the shared grating step.
Should I buy copra or dry my own?
Buying copra gives a simple pressing plant but puts the quality of drying in the hands of suppliers. Drying evenly soon after the nut is split is the main control against mould, and slow drying, wet weather and contact with soil all raise the risk. If you buy, set a moisture and mould check at the gate. If you dry, the dryer and a shell-and-husk-fired heater become part of the plant.
Do I need a refinery for coconut oil?
Only if your customers buy refined, bleached and deodorised oil. Virgin and crude oil need settling and filtration but not neutralising, bleaching or deodorising. Refining is a separate section with its own chemicals, steam and effluent. Compare it with the purchase of refining capacity elsewhere, and see edible oil filtration and refining systems if you decide to add it.
Why does coconut milk curdle or separate when it is sterilised?
The proteins of coconut milk are poor emulsifiers and heat sensitive. On heating, they denature, aggregate and gel, which causes phase separation and flocculation, and high-temperature sterilisation makes this worse. Preheating, homogenisation and stabilisers are the usual ways to keep the emulsion stable. Cream also fouls heat exchangers, so the cleaning cycle should be designed with the heating profile.
How much oil does a nut or a tonne of copra give?
Oil is only part of what leaves the line. Copra is a fraction of the weight of the nuts, oil is a little over half of the copra, and the remainder is meal. Recovery changes with nut maturity, copra moisture, press type and the oil left in the cake, so any quoted figure should state its basis and the route it applies to.
What can be done with shell, husk and press cake?
Each tonne of nuts leaves more by-product than product. Shell and husk can fire the copra dryer or be made into charcoal or biochar, press cake is a feed ingredient, and parings are sometimes extracted for oil. Settle where each stream goes and how it is stored before the main line is drawn, because a poor by-product plan blocks the site.
How do I request a proposal for Coconut Oil & Milk Processing Plants?
Use the Request a Quote page and describe your project. Decide between oil, milk or both, the supply of nuts and the product and pack.
