Coconut milk
Coconut milk is an aqueous emulsion extracted from mature coconut kernel, sold fresh, packaged or reconstituted. It is distinct from the liquid naturally inside a coconut.

Food-rated grater or processor disc · cassava grater · coconut grater · rasping machine
Graters, motorized rasping drums and processor grating discs reduce cassava or coconut to shreds or mash. They perform the grating stage only; later processing determines texture, extraction and cassava safety.
One grating action, several kinds of tool
A grater reduces food by moving it across a rough or perforated surface. Depending on the tool, the result may be shreds, flakes or a wet mash. A hand grater, a processor disc and a motorized rasping drum do the same broad job but are not one standardized machine: scale, drive, feed opening and output differ. The sources do not compare their particle sizes or performance, so a processor disc is a possible home-scale alternative, not a proven equivalent to an industrial cassava grater.
The documented examples show two different scales. A market coconut machine has a metal hopper and motor housing, with a chute for grated coconut. An IITA smallholder guide describes a motorized cassava grater with stainless-steel drum, chute and robust frame. A photo from Nigeria shows a shed-scale machine. None of these sources defines a standard size or universal configuration.
Cassava for gari: the grater is only an early stage
In the IITA guide, peeled and washed cassava roots go through a motorized grater to become wet mash. Its production-scale machine has a stainless-steel drum and food-contact surfaces, powered by a petrol or diesel engine. The equipment table lists 2 tonnes per hour for that context; this is not a rating for a home appliance. The guide also describes traditional graters made from perforated metal sheets and discusses their slower, more labour-intensive use.
Grating is not a stand-alone detoxification treatment. Cassava roots contain cyanide, and the guide treats grating as one part of gari production. Mash must continue through de-watering and fermentation, followed by sieving and roasting. Freshly grated cassava is not ready to eat. The guide warns against pushing roots against the rotating drum with bare hands and recommends stainless steel on food-contact surfaces because mild steel can rust and contaminate the product.

Coconut grating before extraction
A coconut grater prepares the flesh; it does not make coconut milk by itself. A 1993 study of coconut-oil extraction starts with fresh grated coconut meat. One documented route mixes grated flesh with hot water, kneads it, then squeezes and strains out coconut milk. Later settling and separation recover cream or oil; those are extraction steps, not grater functions. The publication reports traditional wet processing in Malaysia, Indonesia, Thailand and other coconut-producing countries, but does not name one grater design for those places.
The same distinction applies to a home processor disc. A grating disc can reduce coconut flesh to smaller pieces, but the study does not test processor discs against hand grating or motorized drums. Disc size and tooth pattern vary by model; the shreds still need the separate water, kneading, squeezing and straining stages specified by the selected method.

Match the grater to its stage
For gari, the grater makes mash; pressing or another de-watering step, fermentation, sieving and roasting follow. For coconut milk, the grater prepares flesh before water extraction and straining. The machine does not replace the press, fermentation stage, sieve or roaster, and it does not validate a food-preservation process.
The cited stainless-steel requirement applies to cassava-processing contact surfaces in the IITA guide. It is not a certification claim about every utensil sold as food-grade. A home processor disc must be assessed by the actual model's materials, guards and cleaning instructions; none of the cited sources compares one with the industrial machines.
History
IITA's 2012 gari guide specifies a motorized stainless-steel drum grater. A 1993 coconut-oil study starts with freshly grated coconut and discusses traditional wet processing. Neither source establishes the first use of hand graters or processor discs.
Equipment details
CapacityThere is no common capacity across this equipment class. The IITA guide lists 2 tonnes/hour for its production-scale grater, not a home-device rating.
SizeThe sources do not establish dimensions for a standard hand grater, processor disc or motorized machine.
PowerNot established This entry covers hand graters, processor discs, electric appliances and engine-driven machines; the taxonomy permits one power source, while the sources show multiple variants.
How you get oneNot established The cited material describes equipment and processing, not a particular seller or current model.
CareThe IITA guide calls for regular cleaning and maintenance of its grater and specifies stainless steel for food-contact parts because mild steel can rust and contaminate the product. Follow the actual appliance's instructions; the sources do not provide one care method for all designs.
Made of
- Stainless steel — Food-contact drum and surfaces in the IITA motorized cassava grater
The guide specifies stainless steel for that processing context, not every home grater or processor disc. - Perforated metal — Traditional cassava grater surface
The guide describes traditional graters as perforated metal sheets; it says these can rust and are hard to keep clean.
Risks and precautions · High risk
Rotating grating surface
The IITA guide warns that pushing cassava against an operating drum with bare hands may cause injury.
Hazard sourceCassava cyanide
Cassava roots contain cyanide; grating is only an early processing stage and does not make fresh mash safe to eat.
Hazard sourceLimits
Grating cassava alone does not remove the cyanide hazard or make fresh mash ready to eat; gari processing continues through de-watering, fermentation, sieving and roasting.

Producing Gari from Cassava: An illustrated guide for smallholder cassava processorsThe guide describes a motorized grater with stainless-steel drum, chute and food-contact surfaces; its equipment table lists 2 tonnes/hour for its production-scale grater.
The guide says grating makes peeled cassava roots into mash and is followed by de-watering and fermentation, then sieving and roasting; grating alone does not complete cyanide reduction.
It specifies stainless-steel food-contact parts, warns that mild steel can rust and contaminate product, and warns against pushing roots against the rotating drum with bare hands.
The guide describes traditional cassava graters as perforated metal sheets and says they are slow and difficult to keep clean.
