Continuous Ball Mill for Grinding Cocoa Liquor

Описание

Это ball mill is primarily designed for the fine grinding of cocoa liquor, achieving a fineness of 20–25 microns; it is widely utilized in chocolate production. The mill is capable of continuous grinding, thereby ensuring a stable output.

Working Principle of the Cocoa Liquor Ball Mill

The equipment utilizes high-strength steel balls as the grinding medium. Through the friction and shear forces generated between the steel balls and the internal cocoa liquor, it rapidly refines the cocoa mass, ultimately achieving the desired fineness (20–25 microns).

This ball mill can be integrated with storage tanks, mixing tanks, and rotor pumps to form a continuous production line, thereby ensuring stable production capacity.

The Cocoa Liquor Grinding Process:

Cocoa beans must first be roasted and crushed into cocoa nibs before undergoing the following processing steps:

1. Initial Grinding

The cocoa nibs are processed through a colloid mill to produce cocoa liquor (a type of suspension). This grinder is a high-speed shear device featuring a core assembly consisting of a stator and a rotor; while its refining capability is less intensive than that of a ball mill, it typically achieves a fineness of 80–100 mesh.

2. Fine Grinding

The cocoa liquor from the initial grinding stage is transferred to a ball mill for fine grinding. The resulting finished cocoa liquor can achieve a fineness of up to 25 microns (approximately 500 mesh) and is then ready for use in chocolate production.

Advantages of the Cocoa Liquor Grinding Mill:

• Achieves Fine Grinding:

The grinding fineness can reach 20–25 microns. It meets chocolate production standards in a single pass, eliminating the need for subsequent regrinding and significantly simplifying the production process.

• Strict Temperature Control Preserves Pure Cocoa Flavor:

Our ball mill features a double-walled, jacketed tubular design. This structure works in tandem with a dedicated cooling system to rapidly and uniformly dissipate the heat generated during grinding. By strictly maintaining the product temperature within a reasonable range of ≤110°C, it prevents high temperatures from degrading the cocoa liquor’s aromatic compounds and compromising its flavor profile.

• Continuous Operation: Stable and Efficient Output

There is no need for frequent shutdowns to load or discharge material. The grinding mill features a continuous-grinding design that integrates seamlessly into continuous production lines, enabling uninterrupted 24-hour operation. This significantly boosts production efficiency while ensuring a stable output, with capacities ranging from 500 to 1,000 kg/h available to suit your needs.

In summary, this ball mill is an ideal choice for the cocoa and chocolate processing industry. It not only dramatically enhances the grinding efficiency of cocoa liquor but also minimizes heat generation, thereby ensuring the stability of both the quality and flavor of the final product.
