Industrial Colloid Mills & Paste Grinding Machines

Feature

⚙️ High-Shear Stator & Rotor :
The core grinding mechanism operates at incredibly high speeds (up to 2900 RPM), subjecting the material to intense shear, friction, and high-frequency vibration for perfect homogenization.
📏 Micro-Adjustable Fineness :
Features an external adjustment ring that allows operators to easily and precisely control the clearance between the stator and rotor, achieving grinding fineness from 50 to 2 microns.
🛡️ Sanitary SUS304/316 Build :
All parts in contact with the product are made of food-grade stainless steel. The dynamic sealing system ensures zero contamination, making it perfect for food and pharmaceutical applications.
🔄 Continuous Flow Processing :
Equipped with a circulating pipe design. Materials can be fed continuously or cycled through the mill multiple times automatically until the desired ultra-smooth texture is achieved.

Working Principle of a Paste Grinding Machine

Liquid or semi-liquid materials are broken down by the high-speed relative motion of the rotor and stator, subjecting the material to intense shear forces, friction, and high-frequency vibrations, which effectively grind, emulsify, and homogenize the material to produce finely processed products.

Maintenance of the paste grinding machine

1. while the paste grinder is in operation, ensure that the bearing temperature does not exceed the ambient temperature. The ambient temperature is 35°C; the maximum temperature should not exceed 80°C. 2. if you hear an unusual noise during operation, please stop immediately to investigate. 3. regularly check the wear on the shaft sleeve; please replace it in a timely manner if significant wear is detected. 4. if the paste grinder is not used for an extended period, you must clean all parts of the pump, dry them thoroughly, install rotating parts, and apply a layer of grease to properly preserve them.

Frequently Asked Questions

Q: Can this machine grind dry materials like whole roasted peanuts without adding oil or water?

A: Yes, absolutely. Roasted peanuts naturally release their own oils when subjected to the high-shear forces of the colloid mill. You can feed dry roasted peanuts directly into the hopper to produce 100% pure, smooth peanut butter without any liquid additives.

Q: My chili paste contains tough seeds and skins. Will it clog the machine?

A: No. The intense shearing action of the toothed rotor will pulverize tough chili skins and seeds. However, for extremely tough materials or to achieve a silkier texture, we recommend utilizing the circulating pipe to cycle the paste through the mill a second time.

Q: How difficult is it to clean the grinding chamber when switching from peanut butter to fruit jam?

A: It is quite simple. The machine is designed for easy flushing. You can run hot water and food-grade detergent through the hopper while the machine is running to flush out the system. For a deep clean, the stator cover can be easily unbolted for direct manual cleaning.
