Hulling & Hull Separation Machinery

Share: FacebookTwitterStumble
Oil seeds like sunflower, neem seeds & seeds of cocoa, coffee needs special impact type huller to recover kernels. After hulling Air Classifier is used to separate loose hulls. There after mixture is graded on special multi desk grader to separate whole Kernels broken kernels un hulled seeds etc. some varieties of seeds need one of the following operations to separate kernels before further processing.
  • De hulling: Sun flower, neem seeds, coffee seeds, cocoa seeds.
  • Decorticating Ground nuts.
  • Cracking Soybeans.
  • De husking: Gram dal, Tuver.
All this operations need different types of machineries depending upon characteristic of seeds cover and kernels. After separation of hulls or husks, separation machineries like air classifier, aspirator columns, pneumatic scalper etc. are used to separate kernels. Important factors to be considered in selection of these machineries are as under
  • Hulling Efficiency
  • Whole kernel Recovery
  • Broken Meat Recovery.


Impact Huller  hot

Impact Huller provides efficient hulling of Sunflower seeds, Safflower, Neem seeds, Palm nuts etc. for further separation of hulls and meats.

Salient Features:
  • Most efficient huller with minimum breakage & fines.
  • Control of speed & feed permits operator to obtain best possible hulling of given material.
  • Cyclone collector and closed air circulation provides dust free working in the plant.
  • Several models are available for capacity up to 3 TPH on Sunflower seed basis.
  • VFD drive permits setting of optimal speed for most efficient hulling of products

Decorticator

Salient Features:-
  • Unlike Impact type huller, this machine loosens husk of groundnut pods under pressure and friction.
  • Grate bars can be set as per grade size of material for most efficient decortications of groundnut pods for minimum breakage
  • Body and drum constructed of heavy gauge steel.

Pneumatic Aspirator

Wildly known as air wash scalper mainly used as pre cleaner before storage of seeds and grains. Floating drum and vacuum system allows control of feed and air for efficient aspiration of light impurities.

Aspirated lights and coarse dust are collected into cyclone through fan suction.

Salient Features:-
  • Increases capacity of next cleaning machine.
  • Controls of feed and air allow adjustments for efficient separation.
  • Eliminates dust from cleaning room.
  • No moving parts.

Aspirator Column

It is widely used as post aspirator unit at discharge chute of screeners /fine cleaners to further clean product 

Salient Features:-
  • It operates under air vacuum system and is most effective for the separation of light weight particles from heavy products
  • It is also used to separate husk/hulls after hulling of seeds like sunflower, neem seeds etc.
  • Uniform air distribution.
  • Air chamber observation window.
  • • Heavy gauge steel construction.
  • It is widely used as post aspirator unit at discharge chute of screeners /fine cleaners to further clean product.

Multi Point Aspirator

Multi point aspiration column design provides a superior method of separating fines from free flowing granular material.  The material is dropped in a free-fall vertical flow path into an opposing upward air stream to suspend the fines in the air stream for removal to the collection system.
Salient Features:-
  • High capacity multi pass aspirator.
  • The cleaning process takes place as the product enters the aspiration columns and is contacted by an airflow which removes light fines, straw, hulls, etc.
  • The cleaned product falls through the aspiration column, which by its design expands the product stream allowing for more efficient cleaning.
  • The aspirated light materials are sucked through the aspiration column and discharged to an outside collection system ,which may include cyclone and blower unit.

Hulls Screen Grader

After dehulling, hull separation is an equally important operation. The hull grader has to employ the most suitable design considering terminal velocity of hulls and kernels. Since, there is wide variation in particle size in the dehulled material, it become a matter of knowledge of separation technology and experience to select suitable air separators.
