A cashew butter processing line is a complete, integrated set of machines that converts roasted cashew kernels — especially lower-grade splits, pieces and brokens — into smooth, shelf-stable cashew butter or paste, then fills and seals it into retail jars or pouches. Cashew Tech sources, specifies and supplies these lines as part of its turnkey and supplies offering, and integrates them into new or existing plants.
The core sequence is: colour sorter → roaster → cooling/de-skinning → grinder/colloid mill (fine paste) → mixing (optional salt/oil) → degassing → filling → capping/sealing. Lines are built in food-grade stainless steel, with optional PLC control, at a capacity confirmed per configuration.
The strategic value is clear: this is value-addition. It monetises kernels that would otherwise sell at a discount as lower grades, turning by-product splits and pieces into a branded consumer product with far higher margin.
The process flow, step by step
| Stage | Machine | Function |
|---|---|---|
| Sorting | Colour sorter | Removes discoloured and foreign matter |
| Roasting | Roaster | Flavour development + moisture reduction |
| Cooling & de-skinning | Cooler / peeler | Removes the testa (red skin) |
| Fine grinding | Colloid mill / grinder | Produces the smooth paste |
| Mixing | Mixer | Optional salt, oil or blends |
| Degassing | Deaerator | Removes trapped air for texture & shelf life |
| Filling | Filler | Into jars or pouches |
| Capping / sealing | Capper | Finished retail unit |
The colloid mill is the heart of the line
The grinder/colloid mill produces the fine, smooth paste that defines the product; grind fineness is specified per recipe. Degassing then removes trapped air for a smoother texture and longer shelf life.
Feedstock: monetising splits & pieces
The line runs on splits (S), pieces and brokens — the grades that fetch a discount as whole-kernel exports (see cashew kernels). Turning them into butter is the fastest route up the value chain for an established processor.
Construction, capacity & integration
Contact parts are food-grade stainless steel, with optional PLC automation. Capacity in kg/h, grind fineness in microns, and recipe (unsalted, salted, oil, blends) are confirmed per configuration — none are invented. For roasting detail see the roasting machine and the roasting process guide; output packs are covered on the retail packaging machine page.
