Why use a cassava grinder in garri production but a rasper in cassava powder production？

In cassava processing, the equipment used at same process stage is specifically selected based on the end product being targeted. Two commonly confused machines are the cassava grinder and the cassava rasper. Although both are used for crushing cassava tubers, their configuration and function vary significantly depending on whether the goal product is garri or cassava powder.

Today, Henan Jinrui, as the professional cassava processing equipment supplier, will introduce two cassava grinding machines and explore why use the cassava grinder in garri production but the rasper in cassava powder production.

The grinding machine is common selected equipment for crushing process in garri production, which can crush cassava while retaining the special flavor of cassava. The cassava particles processed by the cassava grinder are larger, which is conducive to the fermentation and frying processes in the garri production process. There are some reasons for choosing cassava grinder in garri production：

Cassava grinder in garri production

Garri Production Requirements: Garri is a granular fermented food product made from cassava. Its production process requires a mash with moderate texture, rather than ultra-fine particles. The cassava grinder is used to crush peeled and washed cassava tubers into a medium-coarse mash. This texture is ideal for pressing and fermentation.

Efficient Moisture and Toxin Removal: The mash produced by the cassava grinder allows for efficient removal of moisture and toxic components (such as hydrogen cyanide), which is critical for food safety.

Enhanced Frying Process: After fermentation, the mash is roasted to create the final garri product. The coarse texture enhances the frying process, leading to a desirable granular and crispy end product.

Compared with garri production, high-quality cassava powder requires a higher cassava crushing rate. Therefore, cassava rasper is often chosen by cassava powder processors as the best choice of cassava crushing equipment. The following is Henan Jinrui's analysis of the reasons for choosing rasper as a cassava crusher in the cassava powder production process：

Rasper in cassava starch production

Fine and Uniform Texture: Cassava powder requires a much finer and more uniform texture compared to garri. The cassava rasper uses high-speed rotating blades to shred cassava tubers into a very fine slurry.

Efficient Processing: A finer slurry produced by cassava rasper enables more efficient dewatering, drying, and milling processes, which are essential for producing smooth, flour-like cassava powder.

Enhancing Yield: The cassava treated with rasper has a higher crushing rate, which is beneficial to increase the production output of cassava powder. For example, the crushing rate of Henan Jinrui cassava crusher can reach 98%, ensuring maximum cell wall rupture and flour/starch release.

Cassava grinder and rasper are two types of cassava crushing equipment suitable for garri production and cassava powder production respectively. Due to their different configuration structures, the cassava crushing rates are also different. Taking the grinder and rasper manufactured by Henan Jinrui as an example, the crushing rate of the grinder can reach 80%, while the crushing rate of the rasper can reach up to 98%. For garri production, a cassava grinder provides the most suitable texture for fermentation, dewatering, and frying. For cassava powder production, a cassava rasper ensures fine grinding, higher crushing rate, beneficial for the quality and yield of cassava powder. Therefore, it is very important to choose the suitable crushing equipment according to the final product.
