Description

  The present invention relates to a wind selector that can separate processed objects such as beans, cereals, and teas into light and heavy objects using wind power.

  Wind selectors are used in various fields, but are often used in agriculture. In particular, beans and various cereals often have a thin skin on the surface of the fruit, and leaves such as teas are often mixed with unwanted materials such as kaba. It is known that if a thin epidermis remains after roasting these beans, it causes various inconveniences in taste. In addition, if an unnecessary object is mixed in the leaves, the product value is reduced because it is treated as a mixture of a fake object and bitterness is increased.

  For example, when coffee beans are roasted, the epidermis remains on the surface of the fruit at a rate of 20 to 30%, but if the beans are ground and roasted while leaving the epidermis, the bitterness that is extraneous in the resulting beverage It is easy to invite a situation where the astringency remains and the original umami taste is impaired. Also, if the skin remains after roasting cocoa beans, the taste of chocolate will be impaired.

  From this point of view, work is performed to remove unnecessary substances contained in the epidermis and tea leaves remaining after roasting, but it is difficult to remove with high accuracy. Conventionally, as a method for removing such skin, a method has been used in which roasted beans are put in a container such as a cylinder and then blown away by blowing air to the beans with a fan or the like. In this method, there is a problem that the wind does not easily spread over the entire outer surface of all the beans, and as a result, the skin remains without peeling or the peeled skin remains between the beans.

  In addition, when tea is applied to the sorting device, the lump of tea leaves cannot be sufficiently loosened, and it reaches the aspirator in a state where the leaves are not separated. Therefore, there was a problem that the yield was bad.

  Various proposals have been made to solve such problems. For example, the crude tea that has been thrown in is separated into a horizontal tube separation part and a hollow casing part that is tangentially connected to the horizontal cylinder separation part, and the wind is sorted into light tea that contains kava and other tea collections. An apparatus has been proposed. (Patent Document 1).

  In addition, in order to sort the crushed coffee beans into good parts and bad parts by wind pressure, an area is formed just below the hopper to sort the ground coffee beans falling from the hopper into good parts and bad parts by wind pressure. An apparatus has been proposed in which an area for sucking and capturing a defective portion is provided on the side blown away by wind pressure, and a receiving area for the selected excellent portion is formed below the area to be selected (Patent Document 2).

  Further, in the process of placing the separating member in a plurality of stages in the middle of the falling separation portion which is a hollow cylinder extending in the vertical direction, the roasted beans and grains dropped from above, and the like in the process of colliding with the separation member The skin remaining on the surface is peeled and separated, and the separated skin is forcibly sucked into the skin transporting portion extending in the lateral direction, and then collided with a partition plate having punch holes. There has been proposed a device for dropping onto a skin drop recovery section connected to the rear end (Patent Document 3).

  However, the device of Patent Document 1 requires a wind force separating means for centrifuging light brown tea, and a vibration of the receiving plate portion and the comb-like portion extending to the receiving plate portion. Because of this, the device is large. In addition, because it separates and sorts tea containing combs on the comb teeth and fine tea sieving and collecting from the gaps between the comb teeth, it is possible to separate light weights depending on the shape of tea leaves and leaves. There is a bug that there is no.

  The apparatus of Patent Document 2 has a problem in that the light skin is not sufficiently separated because the wind is simply applied to the ground beans and the skin.

  In the apparatus of Patent Document 3, because the fallen fruit and the skin are calibrated to separate only the skin with a fan through a small hole, the skin larger than the small hole is not separated, and the fruit smaller than the small hole is classified as a lightweight object. There is a bug.

It is characterized by.

  Furthermore, at least one of the two or more sorting portions is formed in an arc shape or a screw shape.

  In addition, a control means for adjusting the amount of airflow generated from the airflow generation unit is provided, and the airflow generated from the airflow generation unit rises as turbulent flow inside the sorting unit. .
