Description

Chestnut peel cutting device {CHESTNUT CUTTING APPARATUS}

The present invention relates to a chestnut husk cutting device.

In general, chestnuts are nut fruits, and the inner pulp is protected by a double shell of an inner shell and an outer shell, so in order to process chestnuts as food, the outer shell and inner shell surrounding the fruit must be removed.

The inner and outer skins of chestnuts are firmly attached to the surface of the fruit, so it is very difficult to remove the inner and outer skins from the fruit, and mechanical means for removing them from the fruit have not been developed.

Recently, as the number of suppliers of peeled chestnuts for processed food using chestnuts is increasing day by day, people use tools such as knives and scissors individually to remove the tough outer skin and chestnuts adhered to the surface of the fruit in order. However, there is a problem in that it takes a lot of work time and it takes a lot of labor and time to process a large amount of chestnuts.

In addition, when the skin of the chestnut is removed using a knife or scissors, the appearance of the chestnut is non-uniform, so when removing the skin, a part of the fruit is cut together with the inner skin, reducing the size of the fruit and reducing the marketability.

In order to solve this problem, a peel removal device using chemical or mechanical means is being developed, but in the case of chemical means, there is concern about damage to fruits other than the skin of chestnuts or deterioration of taste due to the use of chemicals. Due to problems such as environmental contamination, the use of chemical peel removal methods is limited.

In addition, the peeling device using mechanical means is difficult to peel the chestnut skins in large quantities, and the chestnuts are put in a processing cylinder with a blade formed therein and rotated at high speed, and as it is rotated, a sheath is formed at chestnuts by the blade or the chestnuts are damaged The skin is removed by the skin removal device, but there is a problem that the product value is reduced by destroying the chestnuts.

At this time, when it is determined that a chestnut having poor marketability is determined among a plurality of chestnuts, the seating block 91 where the chestnut having poor marketability is located may be raised. As shown in FIG. 9 , in a state in which the seating block 91 is raised, the motor unit 93 applies vibration to the seating block 91 so that the seating block 91 may vibrate at a predetermined intensity. By applying a predetermined vibration to the seating block 91, the chestnuts with poor marketability and the chestnuts with good marketability located adjacent to the chestnuts can fall from the corresponding seating block 91 and be seated on another seating block 91 . Thereafter, the seating block 91 may descend to the inside of the housing 92 by the cylinder portion 94 .

The motor unit 93 may vibrate once again in a state in which the seating block 91, on which chestnuts of poor marketability are seated, descends to the inside of the housing 92. At this time, the motor unit 93 may apply vibration of a stronger intensity than when the seating block 91 is raised, so that all chestnuts seated on the seating block 91 fall into the housing 92.

Through this method, balms of poor marketability can be dropped into the housing 92 . At this time, chestnuts with marketability, including chestnuts with poor marketability, seated on the seating block 91 may also fall into the housing 92 . Therefore, the operator can separately select and remove only balms of poor marketability from the inside of the housing 92 .

If the chestnuts with low marketability are not separately separated, and the operation of sorting the chestnuts with low marketability from among the total amount of cut chestnuts is carried out, the work time becomes longer and the sorting operation becomes difficult.

Accordingly, after first sorting the housing 92 through the product discrimination unit 80 and the defect classification unit 90, the work can proceed more quickly by sorting chestnuts with poor marketability among a small amount of chestnuts.

Although representative embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications are possible to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, and should be defined by not only the claims to be described later, but also those equivalent to these claims.
