Project Description

Colloid Mill 

The Application Scope 

Colloid mill is mainly used for ultrafine crushing of wet materials in food, pharmaceutical, chemical and other industries. It can crush, emulsify, homogenize and mix various semi-fluid and milky substances.

It is widely used in vegetable, plant, aloe vera, coconut, pineapple pulp, chili sauce, garlic paste, sesame, cashew nut, walnut, fruit tea, ice cream, fruit jam, fruit juice, soybean sauce, bean paste, peanut milk, protein milk, soy milk, dairy products, malted milk, flavors, condiments, beer, vegetable protein, animal protein and various food and beverages.

Nuts and grains grinding and pulping: It is widely used in peanut butter/milk, almond butter/milk, soy milk, oat milk production, where they grind nuts or seeds into a fine paste, creating a smooth and creamy texture.

Fruit and vegetables wet grinding: when making fruit and vegetable pulp on a small scale, the colloid mill is an ideal equipment to grind the fruits and vegetables into fine pulp.

Sauce, jam and dressings processing:

  • Mayonnaise: Colloid mills are often used in the production of mayonnaise to create a stable emulsion of oil and water. The mill helps achieve the desired texture and consistency.
  • Salad dressings: Colloid mills can be used to emulsify ingredients in salad dressings, ensuring a smooth and homogeneous product.
  • Tomato sauce: The milling process helps break down tomato particles and improve the overall quality of the sauce, resulting in smoother textures and better flavor distribution.

Dairy products:

  • Cheese spreads: Colloid mills can be used to achieve a uniform texture in cheese spreads by reducing particle sizes.
  • Ice cream: Colloid mills may be used to homogenize and emulsify ice cream mixtures, ensuring a smooth and creamy product.

Beverages:

  • Beverage ingredients dissolving: Colloid mills play a role in creating stable emulsions in beverages, such as dissolving the pectins, stabilizers and emulsifiers.
  • Chocolate and cocoa processing: Colloid mills can be used to refine the particle size of cocoa solids in chocolate production.

Working Principle 

Colloid mill is a fine processing machine for wet materials. The principle is that the relative movement of the rotor grinding teeth and the stator grinding teeth under high-speed rotation makes the processed material subject to the combined force of gravity and centrifugal force, and is subjected to strong force when passing through its adjustable annular gap. Shear force, friction force and high-frequency vibration to achieve the purpose of dispersion, crushing, emulsification, homogenization and mixing.

Feature 

A colloid mill is a type of machine that is used for grinding, mixing, and homogenizing materials, especially those that are difficult to reduce in size, such as emulsions and suspensions.

  • In the working process when dealing with heat-sensitive materials, since the rotor will generate high temperatures during high-speed rotation, cooling water can be fed to cool the machine.
  • The machine is composed of body machine, motor, adjusting plate, material inlet and outlet. The body machine is made of SUS304 material, durable and wear-resistant; The adjusting plate can adjust the gear position according to the required material fineness; The material inlet is connected to the hopper and the circulating pipe, so that the material can be grounded circulated; A discharge valve is installed at the discharge port, when the material is refined, the discharge valve can be opened to discharge the material.
  • It is suitable for fine grinding of fluid and semi-fluid materials, and the dynamic and static grinding discs are strengthened, which has good performance.
  • The cleaning of the equipment does not require disassembly and assembly, and the cleaning is convenient. Only need to pass in clean water, the high shear of the equipment will thoroughly clean the interior.
  • Customizable: Colloid mills can be customized to meet the specific needs of different industries and applications. They can be made in different sizes and materials, with various types of rotors and stators to achieve the desired particle size and homogenization.
  • High Shearing Force: Colloid mills use a high-speed rotor that rotates at a very high speed, which generates a high shearing force. This force is responsible for the grinding and homogenization of the material being processed.
  • High Efficiency: Colloid mills are known for their high efficiency in grinding and homogenizing materials. They are capable of reducing particle size to a few micrometers, which makes them ideal for producing fine emulsions and suspensions.
  • The colloid mill can be equipped with a circulation pipe to grind materials with low viscosity that require reflux, such as soy milk, fruit and vegetable pulp drinks; the square mouth without cooling pipe can be used to grind materials with high viscosity such as peanut butter, etc.
  • The flow rate of the colloid mill is not constant. For materials with different concentrations and viscosities, the flow rate changes greatly.
