Grain Dehuller

GRAINS-DEHULLER 

Grain Dehuller to maximize the process output of oilseed, grain and pulses, you need to separate hulls from their kernels efficiently. We offer a wide range of dehulling and hull separation processes which you can tailor to your own product. Loosen and remove the hull with mechanical treatments. Or add a hull control system to further increase process efficiency and yield

We preparation solution delivers top dehulling results leading to a higher protein content in the extraction meal. You have the choice between one or two-stage grain,oil seeds,peas,pulses dehulling. www.immy.cn / www.immyhitech.com 

After the first dehulling stage, the dehulled product contains less than 16 percent residual hulling fragments. 

With a second round, you can further reduce this amount to less than 12 percent to obtain an even higher protein content in the extraction meal. 

After the second stage, a sifter ensures that oil loss during hull separation is as low as possible.

For Soft seeds, such as sunflower, cotton, copra, palm and rapeseeds, have higher oil content than soy and cannot undergo direct extraction. Instead,oil content is reduced to below 20 percent by screw presses and then extracted from the expelled cake in a solvent extraction system. 

For the processing of rapeseed, We offers its expertise in designing and implementing warm and cold preparation processes. 

Copra and palm kernels must further undergo a prereduction by a hammer mill before being processed by a cracking and a flaking mill. 

The flaking mill and its ability to produce consistently thin flakes are key to the efficient extraction of all oilseeds.

We also offers its competence in the designing and implementing of front-end, warm and hot dehulling processes or processes without dehulling. The hot dehulling process sets itself apart through lower energy costs and is suitable for beans containing up to 14 percent of moisture. 

In all mentioned processes, the beans will be optimally conditioned, cracked, dehulled and flaked so that you can get the maximum oil out of them during extraction. The overall fiber content is also reduced, delivering high protein content in the extraction meal.

Soybeans are not only processed to obtain oils and extraction meals, but also for manufacturing high-grade products such as white flakes, protein concentrates and isolates. The food processing industry is transforming these semi-finished products into an ever-expanding range of foodstuffs. Bühler has developed preparation processes in this field that fully satisfy the extracting requirements placed on the end products.
