This coffee destoner machine has the advantages of novel design, simple and easy use, high efficiency, and screening and impurity removal rate of up to 99%, and has become an essential choice for coffee bean roasting and whole grains and roasted seeds and nut. The high quality destoner has automatic wind extraction stone machine, which is a newly developed material that utilizes the specific gravity of the material to filter and remove the impurities to achieve the purpose of purifying the raw materials. We have optimized and improved the machine, added dust bag to protect the environment and reduce the emission of tiny particles.
1. High efficiency
2. High stone removal rate.
3. Low cost, good effect.
4. Easy operation.
5. New upgrade: dust bag, that is a good protection for environment.
6. Adding frequency converters can adjust the wind speed.

Application: the high quality destoner is used for coffee bean roasting and whole grains and roasted seeds and nuts. Or it can be used in factories, outdoors, food shops, building material shops, manufacturing plant.
* It is mainly used for screening and separation of mixed stone metal particles in coffee beans (green beans or cooked beans), which has obvious effects on improving the quality and grade standards of coffee beans, and can also be used for impurity removal screening of granular materials such as grains.
* New upgrade: adding dust bag to protect the environment and reduce the emission of tiny particles.
* Material: stainless steel + black spray paint, increase service life.
* Adding fans and frequency converters can adjust the wind speed. Different coffee beans use different extraction speeds
1. If the stone is not discharged during the production process
| A．The blowback is too large | adjust the blowback air regulator |
| B．The screen surface tilt is too large | adjust the screen surface inclination angle |
| C．The poly slate is closed too tightly | to improve the poly slate |
| D. Screen surface damage | Replace screen surface |
| E．Sieve or air-distributing plate is blocked | Clean the screen surface |
2. The stone contains more coffee beans during the production process
| A． the blowback is too small | adjust the blowback |
| B． the screen tilt is too small | adjust the screen tilt |
| C． the poly slab is too open | adjust the poly slab |
