Colloid Mill Machine

Fruit Colloid Mill Machine for Pulping and Grinding

In fruit or food sauce production, are you facing these common challenges? One is the obvious graininess in fruit pulp or sauces, rough and uneven texture, the second problem is finished products that tend to separate or settle, poor stability, the third is inconsistent quality between batches, and the last challenge is low efficiency with high energy consumption from conventional grinding equipment.

If any of these problems exist, then the equipment you truly need is a colloid mill machine. The colloid mill machine is an indispensable key machine in fruit and food processing. Such as in the jam processing equipment.

If your product contains fruit pulp or requires a smooth texture, a colloid mill machine is usually necessary. Tell us your material and production capacity. Our engineers will recommend the right model of colloid grinder for you.

A colloid mill machine is a fine grinding machine that utilizes the high-speed relative motion between the stator and rotor to generate strong shear, friction, and emulsification effects. It is widely used in the production of fruit products, jams, purees, juices, and various food sauces.

In fruit and food processing applications, a colloid mill machine can rapidly grind fruit pulp and sauce materials into a fine, uniform, and stable slurry within a short time. It significantly improves product texture, enhances batch-to-batch consistency, and creates ideal conditions for subsequent heating, sterilization, and filling processes of the fruit and food production line.

In a complete fruit juice or food processing line, raw fruits are usually pre-processed by a fruit crusher machine before entering the colloid mill machine for high-shear grinding.

Working Principle of Colloid Mill Machine

The core components of a colloid mill machine consist of a high-speed rotating rotor and a fixed stator, the space between them can be adjustable according to the specific processing requirements. In addition, the colloid mill machine is equipped with a main drive unit, an adjustment system, and a cooling system. All key components of the colloid grinder are made of stainless steel, ensuring corrosion resistance, non-toxicity, and compliance with food processing standards.

Designed for different applications, colloid mill machines are available in various processing capacities and are suitable for a wide range of raw materials. Users can select the most appropriate colloid grinder based on their actual production needs. The overall structure of the colloid mill machine is compact, with a small footprint. It is suitable for single-machine use or integration into food processing production lines.

When the material enters the grinding zone of a colloid mill machine by gravity or pump feeding, it is simultaneously subjected to high-speed shear force, intense friction, as well as impact and vortex action. Under these combined effects, fruit pulp and sauce materials are rapidly refined into a slurry with uniform particle size distribution and stable internal structure. Compared with conventional grinding equipment, a colloid mill machine can achieve much higher grinding precision within a shorter processing time.

The rotor speed typically ranges from 2,000 to 18,000 rpm, depending on the model and application. Customized colloid mill configuration for your fruit or sauce processing.

Colloid Mill Machine Advantages

• The colloid mill machine features stable operation, low energy consumption, simple and safe operation, and high processing efficiency. It is easy to maintain and suitable for a wide range of applications.
• Colloid mill machines can grind fruit pulp and sauce materials to an extremely fine state, significantly improving the texture and appearance of the final product. Particle sizes can be reduced to just a few microns, making colloid grinder ideal for producing fine emulsions and stable suspensions.
• The rotor–stator clearance can be adjusted according to material properties and actual processing requirements, allowing flexible adaptation to different fruits and sauce formulations.
• A finer and more uniform slurry facilitates subsequent processes such as heating, mixing, sterilization, and filling, thereby improving the overall efficiency of the entire production line.
• Manufactured from 304 / 316 stainless steel, the colloid mill machine offers excellent corrosion resistance, hygienic performance, and long-term durability, fully meeting food processing standards.
• The colloid mill machine is very easy to clean. Simple water is sufficient, as the high shear forces effectively clean the internal grinding components.
• Colloid mill machines can be customized to meet the specific requirements of different industries and applications. They are available in various sizes and materials and can be equipped with different rotor and stator designs to achieve the desired particle size and homogenization effect. For low-viscosity materials that require recirculation, such as soy milk and fruit & vegetable beverages, the colloid mill can be equipped with a circulation pipe. For high-viscosity materials such as peanut butter, a square inlet design without a cooling pipe is available.
• With a wide range of applications, the colloid mill machine is suitable for processing strawberry jam, blueberry jam, grape jam, tomato paste, chili sauce, and mashed potatoes etc. It can also be used to produce nut butter, almond milk, fruit juice, mooncake fillings, soy milk, ice cream, and various beverages.
• The colloid mill machine offers excellent temperature resistance and can adapt to diverse processing conditions. It supports continuous, large-scale production, meeting the demands of industrial food processing.
• Wear-resistant materials are used throughout the colloid mill machine to ensure a long service life. Its compact size and structure further simplify operation and maintenance.

Colloid Mill Machine Applications

The colloid mill machine is a key piece of equipment for improving the quality of fruit and food sauces. Its multifunctional design and wide range of applications make it a valuable solution for achieving fine, uniform textures and meeting high-level processing requirements.

Food Industry

The colloid mill is widely used for processing fruit purees, fruit pulp-based juices, and blended fruit beverages made from mango, banana, strawberry, apple, pear, tomato, and other fruits. It is also suitable for producing a variety of food and beverage products, including dairy products, chocolate, bean paste, jam, peanut butter, cream beverages, chili sauce, sesame products, fruit tea, ice cream, mooncake fillings, soy milk, and more, ensuring a smooth and uniform product texture.

Beyond the food industry, colloid mill machines are also applied in the chemical industry for the production of pigments, dyes, and emulsified asphalt. In the pharmaceutical industry, they are used for fine processing of syrups, ointments, royal jelly, pollen, nutrient solutions, traditional Chinese medicine preparations, vaccines, and various pharmaceutical formulations. In addition, colloid mills are widely used in the daily chemical and personal care industries for manufacturing toothpaste, shampoo, cosmetics, soap, lip balm, and other consumer products, as well as in various other industrial applications.
