-6- S 1376268 Amendment (May 22, 2012 revision) [Summary of the Invention] (Problem to be solved by the invention) Among the covered skins, the endocarp layer is soft between the puip and the silver film. The endocarp, the silver film is adhered to the outer surface of the seed to cover the thin seed coat of the seed 'but the endocarp layer is easily stripped. However, the silver film is less likely to be removed than the inner skin layer, so that a silver film may remain after the shelling and polishing. • The silver film remains in the coffee green bean temple, and the raw bean is baked into a powder. When the powder is soaked in hot water to make a coffee drink, it contains warm or miscellaneous flavors, and cannot be clean and delicious. coffee. Therefore, when the apparatus is operated in such a manner that the husking and polishing operation is efficiently and completely peeled off and the silver film is removed, the coffee beans are broken. When the coffee beans are not broken and run, it takes a lot of time to make the work efficiency poor. The present invention has been made in view of the above-mentioned matters, and it is intended to completely remove the coated hide without breaking the coffee beans. Other purposes are to plan the efficiency of the shelling and grinding operation. (Means for Solving the Problem) The unshelled polishing device for coffee beans of the present invention comprises: a husking and polishing mechanism for a husking and polishing chamber having a squeezing and grinding roller, wherein the husking and polishing mechanism is in a plurality of stages In the configuration, the upper part of the husking and polishing mechanism is a one-pass type rinsing machine in which the supply port for the coffee beans is placed, and the outlet for the coffee beans and the peeling skin is discharged. A resistance mechanism for adjusting the husking and grinding pressure is provided, and the lowermost husking and grinding mechanism is a one-pass husking and grinding machine. The 1376268 amendment (corrected on May 22, 2012) is provided with a coffee for the husking and grinding chamber. a supply port for the bean and a connection to the suction chamber, a crust net for discharging the peeling skin peeled off from the coffee bean, and an outlet for discharging the coffee beans, and the outlet side is provided with a husking and polishing device for setting the resistance mechanism A resistance mechanism with a lower pressure value. The supply port of the husking and polishing mechanism of the lowermost stage of the present invention is characterized in that it is connected to the outlet of the husking and polishing mechanism of the upper stage by the wind sorting mechanism. The husking and polishing device for a coffee bean according to the present invention comprises: a husking and polishing mechanism having a husking and polishing chamber in which a husking and polishing roller is incorporated, wherein the squeaking and polishing mechanism is a circulating husking and polishing machine. The shell grinding chamber is provided with a supply port that communicates with the funnel, an outlet that communicates with the funnel via a vertical husking and polishing chamber, and a crust net that communicates with the suction chamber to discharge the peeling skin. On the outlet side of the husking and polishing chamber, An auxiliary resistance mechanism for adjusting the unloading and grinding pressure is provided. (Effect of the Invention) Since the present invention has the above constitution, the α-addition bean is subjected to husking and polishing by a peeling and mixing step and a peeling separation step. In the peeling and mixing step, the coated skin removed from the coffee beans in the husking and polishing chamber is crushed while being pressurized and travels toward the outlet, and is discharged from the outlet together with the coffee beans. Therefore, the peeled cover is called "peeled skin". In the husking and polishing chamber, the unpeeled coating skin is removed and buffered, so that the cracking of the coffee beans is prevented. Moreover, in the peeling separation step, the unsealing and grinding pressure is higher than that of the front section.

S -8 - 1376268 Amendment (amended on May 22, 2012) The pressure of the husking and grinding stroke is smaller, and the peeling of the husking and grinding chamber is discharged from the crust net. Therefore, the coffee beans discharged from the outlet of the husking and polishing chamber are non-ruptured and clean coffee green beans. [Embodiment] (Best Mode for Carrying Out the Invention) A first embodiment of the present invention will be described with reference to Figs. 1 to 5 . • The frame 1 is in the form of a segment, that is, at a predetermined interval in the up-and-down direction, the φ is overlapped with three sets - the secondary pass-type husking mill A, B, C» In the uppermost section, for example, 40% of the entire coated skin for peeling the coffee beans G. The husking and polishing machine a is provided with a cylindrical husking and polishing chamber 3A. However, the husking and polishing chamber 3A is disposed in a horizontal shape, and a husking and polishing roller 5 is provided inside. Although the roller 5 includes the case roller portion 5a and the husking and polishing blade 5b, the husking and polishing blade 5b is provided continuously at the end portion before the delivery of the parent portion 5a. Further, the husking and polishing blade 5b may be disposed at an intermediate portion of the feed roller I sub-portion 5a as shown in Figs. 4 and 5 . A supply port 7 is provided at one side end of the husking and grinding chamber 3 A, and an outlet 9 is provided at the other end. The supply port 7 is connected to the funnel π' and a resistance mechanism 13 is provided in the vicinity of the outlet 9. The resistance mechanism 13 is for adjusting the pressure (resistance) of the husking and polishing chamber in the husking and polishing chamber 3A. The resistance mechanism 13 is operated by a dial provided on an operation panel (not shown), and the resistance is changed by rotating the s-hai dial to cause the resistance plate 13a to move away from or contact the outlet 9. In the figure, reference numeral 14 is a roller driving the pulley that drives the husking and grinding roller 5, and is rotated by the main motor 17 on the right side. The main motor 丨7 is fixed -9- 1376268 Amendment (as amended on May 22, 2012) on the base station 15. The husking mill B is disposed in the middle portion, for example, 40% of the entire coated skin for peeling the coffee beans G. The husking mill B is disposed in parallel below the husking mill A, but the orientation in the horizontal direction is opposite to that of the husking mill A. That is, the supply port 7 of the husking mill B is located on the outlet 9 side of the husking mill A. The supply port 7 is connected to the outlet 9 of the husking and grinding machine A by the drop guide path 19. The husking mills A and B have the same structure. Further, the roller drive pulley 14 of the husking mill B is rotated by the motor 2 1 on the left side. This motor is fixed to the base 15 . The husking mill C is disposed at the lowermost stage, for example, 20% of the entire coated skin for peeling the coffee beans G. The husking mill c is disposed in parallel below the husking mill B, but the orientation in the horizontal direction is opposite to that of the husking mill B. Thus, three sets of husking mills A and B are adjusted. When the direction of C is overlapped, it is possible to reduce the size and reduce the arrangement space as compared with the case where it is arranged horizontally. Further, the coffee beans discharged from the outlet of the upper squeegee mill are attached to the supply port of the husking and polishing machine by the weight of the hull mill, so that it is not necessary to provide a hoisting mechanism such as an elevator. The structure of the husking mill C is substantially the same as that of the husking mills a and B, but has the following differences. The air separation portion 23 is provided at the exit guide line 19 of the outlet of the husking mill B and the supply port 7 of the husking mill C. In the wind sorting unit 23, the peeling skin having a lighter specific gravity than the coffee beans is separated from the coffee beans by the wind force, so the supply of the peeling mill C is provided.

-10- S 1376268 Amendment (as amended on May 22, 2012) To the mouth, only the coffee #豆. (2) The peripheral wall of the husking and polishing chamber 3C is a crust net 25. The crust net 25 is formed by a screen that penetrates a long hole shape, but the size of the long hole is, for example, a short diameter of 1.2 mm and a long diameter of 12 to 15 mm. In addition, the screen may also be a slatted web. (3) The husking and polishing chamber 3C is surrounded by the suction chamber 27, and the suction chamber 27 is connected to the wind sorting unit 23 and the cyclone separator 30. Further, reference numeral 3 2 denotes a suction fan, a 3 3 type complete discharge chute for flowing the curry beans, and a 35-belt belt adjusting pulley. Next, the operation of this embodiment will be described. Preparation for operation: Operate the operation panel to set the operation time of the husking mills A, B, and C, and turn the dial to set the magnitude of the husking and grinding pressure (pressure value). The pressure value is set to be the same for the husking mills A and B. For example, it is set to a value that can be unpacked by about 40% of the entire covering skin, and the husking and grinding machine C has a smaller value than the husking and polishing pressure. For example, it is possible to set a value of about 20% of the entire covering body. The rotational speeds of the two main motors 17, 21 are set to three, and the husking mills A, B, and C are all the same. For example, the feed speed of the coffee beans is set to 50 to 100 cm/sec. Start of operation: When the main power source is turned on to start the main motors 17, 21, the respective husking and polishing rolls 5 are rotated, and the coffee beans G in the hopper 11 are discharged from the supply port 7 into the husking and polishing chamber 3A. Then, the coffee bean G is added in the husking and grinding chamber 3 A

S -11 - 1376268 Amendment (Amended on May 22, 2012) The removal of the covered leather is carried out toward the exit 9. At this time, in the coating of the coffee bean G, the inner end peel layer (the peeling skin) k which is peeled off is mainly peeled off, and the inner layer of the peeled skin k is separated from the coffee bean G and pressurized by the j grinding roller 5 By stirring, the peeling skin has an effect of peeling off the unpeeled coating skin even if the surface is broken. Therefore, a good peeling effect can be obtained without making the resistance value of the resistance mechanism 13 more than necessary.

The coffee beans G and the peeling skin k toward the outlet 9 are discharged from the outlet 9. At this time, about 4% of the entire coated skin covering the coffee beans was peeled off. The coffee beans g and the peeling skin k discharged from the outlet 9 fall into the drop guide path 19 and enter the supply port 7 of the peeling mill b. In this case, the husking and pulverizing machine B is subjected to the same method as the husking and pulverizing machine A, and the husk grinding machine B is used, and in the husking and pulverizing machine B, about 40% of the entire covering of the covered coffee beans is peeled off' Therefore, the coffee bean tanning system is in this state, and it is in a state in which about 80% of the entire skin is peeled off, and is discharged from the outlet 9 of the husking mill b in this state. The coffee bean g and the peeling skin k discharged from the outlet 9 fall into the drop guide path 19 and enter the supply port 7 of the peeling and polishing machine c, but receive the wind by the wind sorting portion 23 on the way of falling. In the selection, the peeling skin k and the coffee bean G are separated and attracted to the suction chamber 27. Therefore, only the coffee beans G can be supplied to the supply port 7 of the husking mill c. The coffee bean G' is peeled off by the husking and polishing roller 5' rotating in the husking and polishing chamber 3C, and the coating is carried out toward the outlet 9, but the husking and grinding pressure is higher than the pressure of the husking and grinding machine A and B. It's smaller, so the curry is not broken.

-12-S 1376268 Amendment (Amended, May 22, 2012) Here, the peeled coating is sucked into the suction chamber 27 through the sheath net 25, and then sent to the cyclone separator 30. Then, the peeling skin is separated from the air in the cyclone separator, and then housed in the shell receiving portion 48. The peeling and polishing machine C' is used to cover about 20% of the entire covering of the β-added beans. Therefore, the coffee bean G is discharged from the outlet 9 of the husking mill C to the completion discharge tank 33 in a state in which 100% (all) of the entire peeling coating is removed. Therefore, the second embodiment of the present invention will be described with reference to FIGS. 6 and 7 , but the same reference numerals as in FIGS. 1 to 5 are used to obtain the second embodiment of the present invention. The name and function are the same. In the present embodiment, a one-pass type husking and grinding machine is used instead of the circulating husking and grinding machine D. The funnel 11 of the husking mill D is connected to the supply port 7 of the husking and polishing chamber 3D. Further, the husking and polishing chamber 3D is an outlet type. The side 9 is an inclined husking and polishing chamber which is inclined upward, but the inclination angle thereof can be appropriately selected in accordance with the necessity. In the husking and polishing chamber 3D, a husking and grinding roller 5 having a feed roller portion 5 & and a husking and polishing blade 5b is incorporated. This roller 5 is driven by the main motor 丨7. A coffee bean outlet 37 is provided in the unshelling polishing chamber 3D on the lower side of the feed roller portion 5a. This outlet 37 is provided at the end portion of the husking and polishing chamber 3D, and is opened and closed by the throttle valve 39. The peripheral wall of the husking and polishing chamber 3D is formed by the reticle 4 1 'the outer periphery of the hull net 4 1 is covered by the net cover 45. The cover 4 5 is, for example, shown in FIG. 7 , and is a pair of cover sheets having a semi-arc shape.

-13- S 1376268 Amendment (as amended on May 22, 2012) 45a and 45b, the upper end of which is rotatably supported. Therefore, the net cover 45 is set to be openable and closable. A suction air passage 42 is provided between the bottom of the casing and the drain + 1 i. A suction chamber 43 is provided on the lower side of the casing net 41. The suction chamber 43 is connected to the cyclone type by the hose 44. The outlet 46a of the cyclone 46 is located in the casing receiving portion 48. The outlet 9 of the husking and polishing chamber π is connected to the vertical husking and polishing portion 5 丨丨 in the funnel. Further, the reference numeral 52 is an auxiliary resistance means which can be assisted when the necessary husking and grinding pressure cannot be obtained. J will help with the land. 54 is a supply roller for feeding the coffee in the funnel 11 and G smoothly to the supply port 7. % is the suction fan motor, and 58 is the operation panel. Next, the operation of this embodiment will be described. Preparation for operation:

* Operate the operation panel 58 to set the operation time and the time to open the blocked * net cover 45. This operating time is a regular case. For the time when the coffee beans can be recycled, the time for opening the net cover 45 is the time when the coffee beans are finished to be circulated twice, and the time of the shell grinding chamber 3D is used. 31 e rc ^ 1 and the fan motor 56 are also set to open. Start when the cover is 4 5 . Start of operation: When the main power source is turned on to start the main motor 17, the coffee beans G in the hopper funnel are rotated by the supply roller 54 while being discharged from the supply port 7 while being restricted by the supply roller 54. However, L plus brown beans G in the shelling grinding chamber _, one side peeled off the covering skin (mainly the endocarp layer) while rising toward the outlet 9 -1 - 1376268. Correct this technique (May 22, 2012 correction) The outlet 9 of the 3D is inclined upward, so that the weight of the curry bean in the funnel 11 and the 罝 罝 研磨 研磨 研磨 , , , , , , , , , , , , , , , , , , , , 施加The resistance of the husking and polishing pressure is adjusted... The state of the pressure is increased. The husking and polishing pressure in the husking and polishing chamber 3D becomes an appropriate pressure necessary for the detachment. Further, when the pressure necessary for the peeling is not obtained, the pressure can be adjusted by the auxiliary resistance means 52. In the husking and polishing chamber 3D, the coating of the coffee bean G (mainly the inner φ skin layer) is peeled off, and the peeled coating (peeling skin) k is broken and pressurized with the coffee beans. The peeling skin k further obtains the effect of removing the unpeeled coating skin. The coffee beans and the peeling skin k which are directed toward the outlet 9 are discharged from the outlet 9 to the vertical husking portion 50, and rise to the inside of the vertical husking and polishing portion 5, and return to the funnel 1 1 (the first cycle). The coffee beans G and the peeling skin k which are returned to the funnel 11 are subjected to shelling and polishing in the same manner as described above. In other words, the coffee bean G and the peeling skin k are restrained by the supply roller 54 and enter the supply port 7 again, and are unsealed and polished in the husking and polishing chamber 3D, and returned through the vertical husking and polishing unit 5 The funnel (the second cycle ends the second cycle, and the third cycle is started to perform the husking and polishing. At this time, as shown in the dotted line of Fig. 7, the moving cover sheets 45a, 45b are rotated, The mesh cover 45 is opened and the suction fan motor 56 is driven. Therefore, the peeling skin k supplied to the supply port 7 together with the coffee bean G and the covering skin k peeled off in the husking and polishing chamber 3D pass through the sheath net 4i. It is attracted to the suction chamber 43, and enters the cyclone separator 46 through the hose 44, and is separated from the air and then falls into the casing receiving portion 48. 5 -15- 1376268 Amendment of this '(May 22, 2012) By the third cycle, the silver film is completely removed, and the green coffee beans G1 are not broken and become clean. The motors 17, 56 are stopped and stopped. When the throttle valve 3 is opened, the coffee bean _ G1 Coffee, raw bean export 3 7 flow down in coffee green bean receiving part 40. In this second implementation Although the mesh cover is provided in the form, the mesh cover can be omitted in the manner of visual operation of the circulating husking and polishing machine. The reason is that the coated skin (peeling skin) k which is peeled off at the initial stage is mostly divided. The mesh of the shell net is larger, so it cannot pass through the shell net 4 i as long as it is not attracted. Therefore, the fan motor 5 is not driven in the initial cycle phase, and the final cycle phase, for example, the third time After the start of the cycle, the same effect as described above can be obtained by driving the fan motor 56. Further, in the second embodiment, a circulating type husking and polishing device for coffee beans having an inclined husking and polishing chamber is used, but Instead of the inclined husking and grinding chamber, it is also possible to use a horizontal husking and grinding chamber. This horizontal _ husking and grinding chamber is such that the husking and grinding blasting chambers are horizontal, so the husking and grinding pressure is smaller than the slanting type. Therefore, when the necessary husking and polishing pressure cannot be obtained, the pressure is adjusted by using an auxiliary resistance device provided near the outlet.
