FORM 2 THE PATENTS ACT 1970 (39 OF 1970) COMPLETE SPECIFICATION (SECTION 10, RULE 13) TITLE: "STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY" NAME: Mr. Tukaram Mugutrao Karne ADDRESS: Shreyas Ornate, 95-Tulasibagwale Colony, Sahkarnagar-2, Pune: 411 009, Maharashtra, India. NATIONALITY: A SUBJECT OF THE REPUBLIC OF INDIA. The following Specification particularly describes the nature of this invention and the manner in which it is to be performed: 1 TECHNICAL FIELD This invention relates to "STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY" type sugarcane mill and more particularly to systems for cane crushing mill having several mill units in a in one milling tandem. BACKGROUND Cane sugar industry is passing through a critical phase of set back due to uncertain nature, irregular and insufficient rains and other statutory regulation problems. There are also several technical problems in the sugar industry due to manufacturing defects, acquired inefficiency during modifications, expansions and additions of plant, machinery and equipment. All of these problems contribute to the huge losses to the sugar industry and Nation by way of reduced crushing capacities, lower efficiencies, long duration repeated stoppages, several breakdowns and failures, all resulting in high sugar losses in the process of sugar manufacture ultimately resulting in low sugar Recovery. All of these problems have contributed to the sickness of number of sugar factories in the country. There is a chronic problem, of serious choking at various designs of cane kicker, in the sugar industry. Over feed cane at the kicker is either choked seriously or passed to the leveler from the topside. The cane passing below cane kicker has very irregular poor density of @130 to 150 kg/cub.m. There are several problems due to irregular cane feeding to the cane leveller, cane fibrizer / shredder and mills. All of these problems result in to uncertain as well as irregular milling performance. EXISTING SET UP AND PROBLEMS IN THE SUGAR INDUSTRY There are generally four machines installed for cane preparation. The cane kicker or equalizer, cane chopper or leveller, the cane leveller or cutter and fibrizer or shredder, are installed one after another in series to achieve continuous working and achieve high cane preparation suitable for cane milling process. The desired preparatory index is in the range of 85 to 90%. The cane preparation is expected of shred of long hairy fiber type. The powder formation of sugar cane is supposed to be avoided. PRINCIPLE AND WORKING OF EXISTING CANE KICKER The excess quantity of over feed sugar cane in the cane carrier is kicked back towards the cane yard and normal level of sugar cane shall be allowed to pass, through the clearance set between the tip of arms of the cane kicker and top of the slat of cane carrier, further towards the cane preparatory devices. But there is a chronic problem of serious choking in the various designs of cane kicker in the sugar industry. Therefore the expected simple purpose, of cane kicking of excess sugar cane and regular feeding of cane to the preparatory devices, is never achieved. 2 DESCRIPTION :- In the "STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY" the excess or any quantity of over feed sugar cane in the cane carrier, approaching in vertical or horizontal form, will be chopped off efficiently, thrown back far towards the cane yard but necessarily to fall in the cane carrier. The voids between the cane bundles and below entangled loose cane, are filled up with the chopped off sugar cane pieces. The density of approaching cane is enhanced to @ 200 to 250 kg/cub.m. Normal level of high-density compact sugar cane is allowed to pass, through the clearance set between the tip of knives of Cane Flow Stabilizer and Density Enhancer and top of the slat of cane carrier. The compact, densely, properly leveled and stabilized flow of sugar cane is allowed to pass towards the other cane preparatory devices. The power and speed of equipment are as minimum as possible, only in the required optimum level. The excess sugar cane approaching to the equipment is immediately and efficiently cut out and thrown away far in the cane carrier to fill up empty voids already existing due to batch type cane feeding by the cane feed tables. Excess cane feed to the equipment is never being passed to the leveller or cutter from topside of the equipment. All of the excess sugar cane in the vertical and horizontal state is cut efficiently and not a single excess piece is to be allowed to pass to the leveller or cutter. Cane density proceeding to the leveller and cutter is increased to the higher level of 300 to 350 kg/cub.m, to help improve the total preparatory index and improve the total performance of preparatory devices and milling tandem. DESCRIPTION OF WORKING OF "STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY" Sugar cane comes to the cane sugar factory in the bundled or loose form delivered by bullock carts, tractor-trailers and trucks. It is off loaded and then conveyed through the CC (cane carrier) that travels on the cane carrier in the different shapes, bundles or in the entangled form. It has many gaps and voids in between bundles creating non-continuous less densely flow of sugar cane passing to the CSDE (cane flow stabilizer & density enhancer). Thus the in let cane density is in the range of 150 to 175 kg/cubic meter. The CSDE (cane flow stabilizer & density enhancer) has specially designed knives having two sharp edges, one on the main knife MN and another on the piece CN (cross knife). The tip of the MN (main knife) cuts the excess horizontal cane and the CN (cross knife) cuts the excess pieces of vertical sugar cane. The CSDE (cane flow stabilizer & density enhancer) is designed to rotate in the reverse direction as compared to the travel of IC (incoming cane) on the cane carrier. The CSDE (cane flow stabilizer & density enhancer) rotates with the speed in the range of 3 250 to 300 rpm with the pre-set clearance between tip of knives and top of cane carrier stats. CSDE (cane flow stabilizer & density enhancer) is connected to the electrical motor through the speed reduction gearbox. An excess quantity of sugar cane coming to the CSDE (cane flow stabilizer & density enhancer) approaching in the vertical or horizontal planes is chopped off efficiently, thrown back towards the cane yard but necessarily CCP (cut cane pieces) to fall in the cane carrier. The voids and gaps between the cane bundles and below entangled loose cane are filled up with the copped off sugar cane pieces. The flow is stabilized by cutting and chopping off excess sugar cane on the CC (cane carrier) by the CSDE (cane flow stabilizer & density enhancer). The precisely controlled quantity of densely prepared sugar cane then is allowed to pass to the CK (cane cutter). The density of cane passing below CSDE (cane flow stabilizer & density enhancer) is enhanced from 200 to 250 kg/cubic meter. The partially densely prepared sugar cane by CSDE (cane flow stabilizer & density enhancer) is further finely cut by the cane cutter to increase the cane density to 300 to 350 kg/cubic meter. Further the WPC (well-prepared cane) by CSDE (cane flow stabilizer & density enhancer) and cane cutter CK (cane cutter) proceeds to the cane fibrizer or shredder to compete the cane preparation with higher cane density of 400 to 450 kg/cubic meter and higher cane preparatory index of 85 to 90% suitable for sugar milling process. Thus the CSDE (cane flow stabilizer & density enhancer) is a very useful concept of a new machine for the sugar cane industry. It truly stabilizes cane flow and enhances the density of sugar cane proceeding to the milling tandem. The crushing capacity is increased, cane preparatory index is improved and performance of cane preparatory devices and milling tandem is improved to the great extent with the help of CSDE (cane flow stabilizer & density enhancer). CONSTRUCTION AND OPERATION OF "STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY" 1. The tip diameter is in the range of 1400 to 1500 mm. 2. The installed power is 0.75 to 1.10 bhp/tch crushing rate at 15% fiber on cane. 3. The rotary speed of the rotor is 300 to250 rpm. 4. The final sugar cane cutting speed at the tip of knife is 22 to 20 meters/second 5. The direction of rotation of rotor is revered with respect to the cane traveling to the sugar cane milling tandem through cane carrier. 4 6. The clearance below the tip of knife up to the top level of cane carrier slat is 5.25 times the clearance below cane leveller and with respect to that of cane cutter is 36.75 times. 7. The ratio of clearance below leveller to cutter remains unchanged 7.00 8. There is one working sharp edge for cutting the excess sugar cane in the horizontal plane and one more edge for cutting the excess sugar cane in the vertical plane. 9. The main and cross knives are made up of silicon manganese alloy steel IS: 8461-1977 and working edges are hard faced by satellite alloy metal for best possible abrasion, wear and chemical resistant properties. The cross cutting knife is in a welded construction at the extreme end of main cane knife, leaving end margin of @ 75mm for strength. The length of the cross cutting knife is 80 tol00 mm; width is 75 to 80 mm. 10.The number of knives on the rotor is arranged in the eight equal rows. Total number of knives is 21 to 22 per meter width of the cane carrier. The final total number of knives to be fitted on the rotor is divisible by a basic number four. The knives fitted on each consecutive row are staggered to cover complete width of cane carrier; at the same time knives fitted on opposite rows are in one radial line. The knives fitted on opposite rows are equal in number and weight, for static and dynamic balancing. 11.The holder hubs are made up of abrasion resistant cast steel material IS: 1030-1974 Grade CS 65. 12.There are at least three nut bolts of adequate cross section for each knife holding firmly with the holder hub. 13.A machined and well-balanced flywheel is fitted on NDE to reduce the peak load to 150% of the full load. 14.There is a hinged defector flap located at the vertical center above the rotor assembly to avoid overriding of the cane pieces and proceeding to the cane leveller or cutter. 15.The specious safety guard is provided to avoid the flying sugar cane pieces to travel to the lateral sides of the cane carrier causing injury to the people engaged in off loading the sugar cane to the feed tables and cleaning the cane yard. There should be enough specious room for the 5 excess cane cut out by the "STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY". 16.The two fold hinged flaps are provided at least 3 meters away from the rotor towards cane yard. The height of the flaps is limited so as to allow some excess cane pieces to fly out and settle in the cane carrier voids. 17. All the problems faced by equalizer and cane kicker should be solved by the new design of "STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY". DESCRIPTION OF DRAWING FIG. 1 is a somewhat diagrammatic representation of a STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY.

DETAILED DESCRIPTION Referring to FIG. 1, in the STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY, sugar cane conveyed trough the cane carrier (1) that travels on the cane carrier (1) in the different shapes, bundles or in the entangled form. It has many gaps and voids in between bundles creating non-continuous less densely flow of sugar cane passing to the cane flow stabilizer & density enhancer (2). Thus the in let cane density is in the range of 150 to 175 kg/cubic meter. The cane flow stabilizer & density enhancer(2) has specially designed knives having two sharp edges, one on the main knife (3) and another on the cross knife piece (4). The tip of the main knife (3) cuts the excess horizontal cane and the cross knife (4) cuts the excess pieces of vertical sugar cane. The cane flow stabilizer & density enhancer (2) is designed to rotate in the reverse direction as compared to the travel of incoming cane (5) on the cane carrier. The cane flow stabilizer & density enhancer (2) rotates in the range of 250 to 300 rpm with the pre-set clearance between tip of knives and top of cane carrier stats. Cane flow stabilizer & density enhancer (2) is connected to the electrical motor through the speed reduction gearbox. An excess quantity of sugar cane coming to the cane flow stabilizer & density enhancer (2) approaching in the vertical or horizontal planes is chopped 6 off efficiently, thrown back towards the cane yard but necessarily cut cane pieces (6) to fall in the cane carrier. The voids and gaps between the cane bundles and below entangled loose cane are filled up with the copped off sugar cane pieces. The flow is stabilized by cutting and chopping off excess sugar cane on the cane carrier (1) by the cane flow stabilizer & density enhancer (2). The precisely controlled quantity of densely prepared sugar cane then is allowed to pass to the cane cutter (7). The density of cane passing below cane flow stabilizer & density enhancer (2) is enhanced from 200 to 250 kg/cubic meter. The partially densely prepared sugar cane by cane flow stabilizer & density enhancer (2) is further finely cut by the cane cutter to increase the cane density to 300 to 350 kg/cubic meter. Further the well-prepared cane (8) by cane flow stabilizer & density enhancer (2) and cane cutter (7) proceeds to the cane fibrizer or shredder to compete the cane preparation with higher cane density of 400 to 450 kg/cubic meter and higher cane preparatory index of 85 to 90% suitable for sugar milling process. Thus the cane flow stabilizer & density enhancer (2) is a very useful concept of a new machine for the sugar cane industry. It stabilizes cane flow and enhances the density of sugar cane proceeding to the milling tandem. The crushing capacity is increased, cane preparatory index is improved and performance of cane preparatory devices and milling tandem is improved to the great extent with the help of cane flow stabilizer & density enhancer (2). Referring to FIG. 2, in the STABILIZATION AND PRECISE REGULATION OF CANE FLOW WITH ENHANCEMENT OF CANE DENSITY FOR CANE SUGAR INDUSTRY, there are specially designed knives having two sharp edges, one on the main knife (1) and another on the cross knife piece (2). The tip of the main knife (1) cuts the excess horizontal cane and the cross knife (2) cuts the excess pieces of vertical sugar cane. Both are arranged in the eight equal rows. Total number of knives is 21 to 22 per meter width of the cane carrier. The knives fitted on each consecutive row are staggered to cover complete width of cane carrier; at the same time knives fitted on opposite rows are in one radial line. The knives fitted on opposite rows are equal in number and weight for static and dynamic balancing.
