JP2013066697A - Device for removing astringent coat called chaff and fine power of crushed coffee beans - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve such problems that a device for removing astringents coats or fine power is suggested, such as a removal device just like a fanning mill or a device for removing by separating by winding coffee materials crushed by a coffee mill while the materials fall in a passage, since astringent coats, called chaff, and finely crushed fine power are left when roasted coffee beans are crushed by the coffee mill, causing a harsh taste or unpleasant taste, however, these devices can not completely remove the astringent coats or fine power, and are not put to practical use.SOLUTION: The crushed coffee beans are put into a cylindrical container whose upper part is cylindrical, lower part is conical, and bottom part is equipped with a stirring device. A lid with an exhaust tube and a filter is fixed to the cylindrical container. The air pressured from an air supply opening at the upper part of the cylindrical container by an air supply blower sucks the relatively light small astringent coats or fine power mixed in the crushed coffee beans from the lower part of the exhaust tube to separate them from the relatively heavy crushed coffee beans. The separated astringent coats or fine power pass through the exhaust tube, and are caught at the filter part. Thus, the device removes the astringent coats or fine power of the crushed coffee beans.

Description

  The present invention relates to an apparatus for removing coffee beans crushed into fine powder and astringent skin (chaff) mixed in roasted and crushed coffee beans.

  When roasted coffee beans are crushed with a coffee mill, finely pulverized fine powder is produced. This astringent peel (chaff) and fine powder cause an astringent taste and a miscellaneous taste when extracting coffee. Therefore, an apparatus for removing the astringent skin (chaff) and fine powder has been proposed.

  There has also been proposed a device for removing chaff and fine powder that mimics farm tools that remove rice husks and straw debris by wind from threshed grains called Karatsu. This tangled device simply blows the coffee material that is falling and cannot completely separate the coffee from the chaff, and the separated chaff is released into the atmosphere and completely removed. It's hard to call it a device.

  There has also been proposed a coffee mill having a coffee material that is crushed and made to collide with a net in the middle of falling down a passage, and at this time the wind is applied to separate and remove the caff and coffee. In this apparatus, the dropping speed control mechanism in the middle of the coffee material falling is complicated. Further, the structure of the mill is further complicated, for example, the handle of the mill interferes with a forced ventilation mechanism that generates wind or an air passage.

  The present invention is an apparatus that easily separates and removes a small specific gravity astringent crust (chaff) and finely pulverized fine powder mixed in roasted and crushed coffee beans into a large specific gravity of crushed coffee beans.

  According to the present invention, a lid provided with an exhaust pipe and a filter case having a lower end extending up to a conical portion of a cylindrical container and a lower end extending to a conical portion of the cylindrical container is fixed to the upper part of the cylindrical container. The filter case has a removable filter on the inner periphery of the filter case, and is a coffee beans astringent peel (chaff) and fine powder removing device crushed and crushed.

  The present invention is an apparatus for removing coffee beans that have been roasted and crushed and provided with an opening for feeding air to the upper side surface of a cylindrical body of a cylindrical container.

  The present invention is characterized in that the driving source of the stirring device is installed in the outer casing of the cylindrical container, and the driving source and the cylindrical container having the stirring blade can be separated. And a fine powder removing device.

  The present invention is an apparatus for removing coffee chaff and fine powder that has been roasted and crushed, characterized in that a stirring device in which a drive source and a stirring blade are integrated is provided at the bottom of a cylindrical container.

  The present invention is a coffee mill astringent crust (chaff) and a fine powder removing device, in which a coffee mill, a roasted and crushed coffee bean peel and a fine powder removing device are integrated.

  The effect of the present invention is to provide coffee lovers with crushed coffee beans from which astringent crust (chaff) and fine powder mixed in roasted and crushed coffee beans, which cause a taste and miscellaneous taste, are removed. It can provide delicious coffee beans that Ainu lovers have sought without sacrificing the original taste of coffee.

  Hereinafter, the structure of the crushed coffee bean peel (chaff) and the fine powder removing device of the present invention will be described. Crush coffee beans mixed with roasted and crushed astringent crust (chaff) and fine powder are put into a cylindrical container equipped with a stirrer at the bottom with the upper part squeezed into a straight barrel and the lower part conical. Install an air supply blower in line with the air pressure feed opening on the upper side of the straight body. An exhaust pipe having a lower end extending to the conical portion of the cylindrical container and a lid provided with a filter case with a removable filter attached to the upper part thereof are fixed to the upper part of the cylindrical container.

Hereinafter, the operation of the apparatus for removing finely ground coffee (chaff) fine powder of the present invention will be described. The roasted and crushed coffee beans mixed with astringent skin (chaff) and fine powder are put into a cylindrical container. Operate the air supply blower to pump air. The pumped air circulates around the exhaust stack, increasing the speed along the conical throttle and creating a negative pressure at the bottom of the exhaust stack.
Small chaff and fine powder close to the surface mixed with the crushed coffee beans are sucked into the exhaust pipe. The agitator provided at the bottom of the cylindrical container is operated in order to suck the astringent skin (chaff) and fine powder mixed in the bottom and inside of the coffee beans in the cylindrical container.

  The astringent skin (chaff) and fine powder sucked into the exhaust pipe pass through the exhaust pipe and are captured and stored by the filter of the filter case. Clean air is released to the outside.
