Abstract
The present invention relates to development of an integrated small-scale pulse mill which dehusks pulses and separates husk, powder and dehulled pulses in a compact integrated unit.
Claims (16)
1. An integrated small-scale pulse mill for milling different types of pulses, said mill comprising:
a feed hopper (A) provided with a control mechanism being fitted atop a top side of a milling chamber (B) for controllably feeding the pulses to the milling chamber, wherein said milling chamber dehulls the pulses and produces a mill stream consisting of whole dehulled grains/dhal, husk and powder;
said milling chamber comprising of a truncated cone rotating inside a woven wire mesh cage;
a chute (C) being provided at a bottom side of the milling chamber for removing the mill stream from the milling chamber and feeding the same to an aspiration system (G) comprising of an expansion chamber;
said expansion chamber being coupled to a centrifugal blower (H) for delivering air at a predetermined air flow rate and pressure and a dust collector for separating the powder from the mill stream;
said aspiration chamber being coupled to a sieve through a shaft for separating the husk from the whole dehulled grains;
said milling chamber, aspirating chamber, shaft and the sieve being coupled to a driving mechanism, and the whole mill being mounted securely on a sturdy frame structure.
a feed hopper (A) provided with a control mechanism being fitted atop a top side of a milling chamber (B) for controllably feeding the pulses to the milling chamber, wherein said milling chamber dehulls the pulses and produces a mill stream consisting of whole dehulled grains/dhal, husk and powder;
said milling chamber comprising of a truncated cone rotating inside a woven wire mesh cage;
a chute (C) being provided at a bottom side of the milling chamber for removing the mill stream from the milling chamber and feeding the same to an aspiration system (G) comprising of an expansion chamber;
said expansion chamber being coupled to a centrifugal blower (H) for delivering air at a predetermined air flow rate and pressure and a dust collector for separating the powder from the mill stream;
said aspiration chamber being coupled to a sieve through a shaft for separating the husk from the whole dehulled grains;
said milling chamber, aspirating chamber, shaft and the sieve being coupled to a driving mechanism, and the whole mill being mounted securely on a sturdy frame structure.
2. An integrated small-scale pulse mill as claimed in claim 1, wherein the control mechanism is a mechanical control mechanism, electrical control mechanism or a pneumatic control mechanism.
3. An integrated small-scale pulse mill as claimed in claim 1, wherein the milling chamber consists of a top and a bottom open truncated cone shaped wire mesh cage having inside it a concentrically placed rotatable abrasive coated cone having a base angle in the range of 45° to 85°, the said coated cone being fixed atop a vertical shaft being rotatably fixed onto a support structure by fixing means and coupled to a prime mover.
4. An integrated small-scale pulse mill as claimed in claim 3, wherein the milling chamber consists of a truncated cone, coated with emery or carborundum or resinoid material with particle size of Aluminium oxide or silicon carbide or both of mesh size in the range of 8 to 40 BSS mesh.
5. An integrated small-scale pulse mill as claimed in claim 3, wherein the base angle greater than 60°.
6. An integrated small-scale pulse hill as claimed in claim 3, wherein the truncated cones are cast on a fabricated MS or Cl conical base and are provided with provision to mount the said cone on a shaft.
7. An integrated small-scale pulse mill as claimed in claim 6, wherein the diameter of the shaft is in the range of 25 to 75 mm.
8. An integrated shall-scale pulse mill as claimed in claim 3, wherein the truncated cones are mounted vertically on the shaft such that they allow gravity assisted flow of material.
9. An integrated small-scale pulse mill as claimed in claim 1, wherein the diameter of the truncated cone is the range of 100mm to 300mm at the top and 350mm to 450mm at the bottom; with a curved surface area of 1500 to 3000 cm2 .
10. An integrated small-scale pulse mill as claimed in claim 1, wherein the said cone is fixed to the vertical shaft and rotates inside a spring steel or woven wire mesh screen cage of 8 to 24 BSS mesh concentric to the said cone, to get the dehusking capacity in the range of 75 to 100 kg/h.
11. An integrated small-scale pulse mill as claimed in claim 1, wherein the clearance between the cone and wire mesh screen is vertically adjustable, to attain a clearance of 2mm to 20mm.
12. An integrated small-scale pulse mill as claimed in claim 1, wherein the peripheral speed of the said cone is in the range of 500 to 1500 m min-1 for dehusking different variety of pulses such as Tur, Bengal gram, Green gram, Black gram, Horse gram and Lentil.
13. All integrated small-scale pulse mill as claimed in claim 1, wherein the aspiration chamber is designed to suit a capacity of 80 to 100 kg of mill stream products per hour with the centrifugal blower running at 2000 to 4000 rpm delivering air pressure of at a volume flow rate of 200 - 400 ft3 min-1 for aspiration of 10 to 25 leg of light material per hour.
14. An integrated small-scale pulse mill as claimed in claim 1, wherein the dust collection system consists of an inlet and an outlet ducting connected to a cyclone collector for collecting the said aspirated light material.
15. An integrated small-scale pulse mill as claimed in claim 1, wherein the milled product fall under gravity on to a reciprocating sieve deck driven through an eccentric of 10 to 30 mm eccentricity or driven by a vibratory motor with sieves having round and oblong openings ranging from 2mm to 5mm for separation of brokens, dhal and whole grains of different pulses so milled, with the sieves being interchangeable to accommodate different sizes of brokens, dhal and grains.
16. An integrated small-scale pulse mill as claimed in claim 1, wherein the entire system described above is mounted on a single or multiple sturdy frame(s) constructed out of mild steel angles, flats, channels, pipes that are square, round or rectangular.
