multi grains color sorting machine, coffee bean optical sorting machine

Zhongke color sorter

Helps processors meet stringent safety standards

Maximises product value and yield

Delivers consistent performance and stability

Increases productivity and lower operational costs

Our CCD color sorter machine features

1,Advanced image acquisition system

The color sorter machine use the high resolution monochromatic camera or RGB

camera with high quality industrial lens to achieve clear and accurate image acquisition .The

camera could capture the micro defects of material instantly.

2,High reliability

The optical sorters use high signal-to-noise ratio sensor and anti-interference circuit

system,which could highly improve stability and reliability.

3,Intelligent image processing algorithm

Color sorting algorithms of gray level,color difference and HSV are perfectly combined with

shape sorting algorithms of size,circular degree,texture etc,and successfully solved a series

of high difficulty color sorting problems,and dramatically enhance the sorting accuracy.

4,Unique chutes processing technology

The special anodizing and hardening technology can greatly improve the channel smoothness

and ware resistance to guarantee high production.

5,High quality solenoid valve(ejector)

The color sorters are equipped with high quality solenoid valve.The valve has longer

lifespan ,high frequency ,and low air consumption.The working frequency is 1000 times per

second,which guarantees the accurate and perfect ejecting.For the different sizes and

characteristics of material particle, The optical sorters use the solenoid valve of

different sizes.


6,High efficiency and reliable light source

Advanced LED lighting technology with advantages of super high intensity,long lifetime and

perfect performance.

7,Simple operation, easy to learn and use

Simple optical system design, precise automatic correction system, combined with the

well-designed human-machine interface to simplify the complexity of machine commissioning

and use, ensuring the simple operation and the machine is easy to learn and use.

Coffee Sorting

Delivering the highest standards in product quality and safety,it provides  optical sorting

solutions for coffee processorswho demand high standards in product quality and safety. With

a focus on precision sorting and consistent yield, the color sorters meet requirements

of small, medium and large processors who sort a variety of beans;roasted,semi/fully washed sun

dried green  Robusta and Arabica.Its commitment to substantial investment in R&D ensures that

its advanced optical sorting technology produces excellent results in removing even the most

challenging of defects.


We can sort in robusta coffee, arabica coffee and roasted coffee all type of contaminants:

black, brown, reddish,amber beans, immature beans, insect damaged coffee.
