Description

 A device for removing chaff and fine powders from roasted coffee beans crushed {Coffee chaff winnow}

  In the present invention, the roasted (roasted) coffee beans (chaff) and fine powders generated when crushing or crushing coffee are crushed and tasteless when coffee is extracted. It is a device that separates and removes the chaff and the fine powder because it is the cause.

 When coffee beans that have been roasted are crushed / crushed with a coffee grinder, chaff and finely pulverized fine powder are generated, and the coffee and the fine powder are coffee ( When coffee) is extracted, it causes spicy taste and miscellaneous taste. Therefore, it is necessary to remove this chaff and fine powder, and it is currently used in many places by roughing it by hand or blowing it by mouth. This is not efficient and has hygiene problems.

 In general, grains (beans, etc.) and husks are used as agricultural implements to remove chaff, rice straw, and shavings from the threshed grains by wind.

 Coffee can also be partially made with a machine such as a tuyere in the pre-roasting stage, and part of the chaff is removed (burned by heat) during the roasting process.

 However, the chaff remaining after roasting remains with the crushed particles of coffee and the fine powder generated during crushing after crushing / grinding for coffee extraction.

 It is good to remove the coffee (coffee) by affecting the taste (spicy taste and clutter).

 A device for collecting chaff from a large amount of roasted coffee has been devised in order to remove farm equipment that removes rice flakes from the grains, such as pung-gu, by chaffing the grain, but it is a real user. It does not fit the field, and after crushing / crushing, further removal of chaff and fine powder is required.

 The following conditions, properties, and conditions of crushed coffee beans (coffee) are different. 1) Types of beans (types of origin and beans) and conditions (difference between hardness and specific gravity) and roasting during roasting. The Italian roaster is classified into about 8 stages, and the volume is about 1.5 times larger. 2) Depending on the type of grinder and coffee extraction method, the particles of crushed coffee beans are from about 16 mesh (loop) to about 60 mesh (loop), 3) according to changes in the surrounding environment (humidity, temperature) , Because the nature and condition of coffee beans are changed, it is extremely difficult to remove chaff and fine powder due to various properties and conditions.

 The present invention is solved by a method of taking out defective parts (chaff and fine powder) by removing the good parts and bad parts using a separation container and easily separating them with a closed structure of the device using the tuyere principle.

 A cup structure with a conical shape on the bottom to put roasted coffee beans into a cylindrical container (4) with a whistling device at the bottom and a discharge path of a certain way to enter the cylindrical container Small chaff of specific gravity mixed with crushed coffee beans, such as air that is fixed to the lid and is compressed according to the slab (discharge passage) 5 in the upper intake port 6 of the cylindrical container. And the fine powder is sucked and separated from the bottom of the exhaust passage, and the large-scale crushed coffee is left at the bottom of the cylindrical container, and the separated chaff and fine powder are collected along the exhaust passage to the upper layer of the container. The coffee beans are crushed and separated and removed (7).

  At the top of the cylindrical container where a slab (discharge passage) (5) that can enter the cylindrical container (4) with a whistle is placed in the place where the roasted coffee beans are placed. There is an intake port (6), fixed together with the upper portion of the cylindrical container, and sucked through the suction port (9) at the top of the upper cap (lid).

 As a result, the air conveyed to the intake port rotates around the side of the container and the discharged co-worker, and suctions small chaff and fine powder with a small specific gravity through the discharge passage. The inner shell and the fine powder are rotated and simultaneously moved to the upper surface to separate them from crushed coffee with a high specific gravity.

 In order to achieve this purpose, the whistling device on the bottom of the cylindrical container should have a close-contact structure so that it can be easily separated from the container. .

 The inlet of the inner shell (chaff) and fine powder and the air to be transported and the sleeve (discharge passage) have a trumpet-shaped structure, making it easy to separate the crushed coffee beans from the inner shell (chaff) and fine powder In this case, the length of the sleeve (discharge passage) is adjustable according to the amount to be separated from the sleeve (discharge passage).

 At the top of the container, there are five intake vents, which flow from the top to the bottom along the sleeve (discharge passage) with the vortex of the intake air. Passage).

 As described above, the present invention is used to easily and hygienic (existing by hand roughly or blown by mouth) the chaff and the fine powder from the roasted coffee beans. This is not efficient and has problems with hygiene.) It is safe for those who produce and drink hygienic and tasty coffee to producers by resolving the cause of spiciness and taste (waste) when coffee is extracted. And serve delicious coffee.

FIG. 2 is a front view of the configuration of a chaff and a fine powder removing device-Coffee chaff winnow of crushed coffee.
FIG. 3 is a structural diagram of the configuration of a chaff and a fine powder removing device-Coffee chaff winnow of crushed coffee.
Figures 4 and 5 show the flow of the airflow of the chaff and fines removal device-Coffee chaff winnow of the crushed coffee beans.
FIG. 6 is a portable device of a coffee chaff and fine powder removing device-Coffee chaff winnow of crushed coffee.
The present invention relates to a device for removing chaff and fine powder mixed with coffee beans from crushed coffee beans roasted from crushed coffee beans. Will,
Stirring coffee in a cylindrical container with a magnetic whipping device (3) at the bottom, where the lower part holds the roasted coffee beans in a conical cup structure (4). It is rotated by a motor at the bottom of the machine to support the crushed coffee beans.
A certain length sleeve (discharge passage) 5 that can enter there is fixed to the lid-shaped cylindrical container, and air is forced along the sleeve (discharge passage) from the upper intake port 6 of the cylindrical container.
When the crushed coffee beans are supported by the stirring device, the compressed air is suction-separated through the sleeve (discharge passage), which has a small specific gravity among the mixed ones, and the specific gravity is large. The ground coffee is left at the bottom of the cylindrical container,
Separated chaff and fine powder are collected along the sleeve (discharge passage) into the upper portion 7 of the lid-shaped container.
The lid-type container upper layer lid (8) is connected to the inlet (9) by a tube and sucks air by a motor, so that air from the lower intake unit (6) of the container is vortexed into a sleeve (discharge passage) and chaff and fine powder. Make this move.
The sleeve (discharge passage) can be adjusted in the form of a slide or screw type according to the amount of crushed coffee beans input, and it is shaped like a trumpet at the entrance of the passage.
In operation, the timer 13 is displayed to prevent excessive operation, and the device is protected by a timer setting function.
