Horizontal type colloid mill

Types of Horizontal Type Colloid Mills

A horizontal type colloid mill comes in different variations depending on the material, product, working capacity, and purpose. Generally, there are two main types:

• Pure Food Grade: A pure food-grade colloid mill is designed specifically to process food products and complies with sanitary food standards. It is primarily used to make food emulsions, purees, spreads, sauces, and other food products. The machine is manufactured wholly out of food-grade stainless steel and approved hygienic components for quality food processing. Moreover, the food-grade colloid mill features hygienic designs, including closed grinding chambers, washable surfaces, and minimal dead spaces to prevent bacteria buildup.
• Hygienic Food and Non-Food Grade: The non-food colloid mill machine is intended to handle industrial materials like adhesives, inks, and sealants. It is manufactured with less hygienic and more industrial-grade materials for manufacturing. Nonetheless, some colloid mills that process non-food products can be modified to achieve food-grade specifications. Typically, these models will have food-grade rubber and stainless steel components. They will also have more sanitizing options like CIP and fewer dead spaces. Overall, the machines are more versatile and can process both food and non-food products. It is crucial to note that the colloid mill for food products has to meet strict hygiene requirements, unlike those processing industrial products.

Besides the two main types, colloid mills can also be classified depending on their operation. For instance, the planet offers both horizontal and vertical mills, and while the latter is more common, horizontal colloid mills are preferred for their high-efficiency grinding. When comparing a homogenizer colloid mill with a standard colloid mill, the former ensures even finer particle size reduction and better dispersion, which is essential for industries like pharmaceuticals and cosmetics where product consistency and stability are critical.
