A rotary nut cracker

Abstract

The invention discloses a rotary nut cracking machine, which comprises a supporting device. The upper end of the supporting device is provided with a receiving device which is rotatably mounted on the upper end of the supporting device. The upper surface of the receiving device is provided with a plurality of annular grooves, and the centers of the ring grooves coincide with each other. However, the radius gradually increases, and the width and depth of the annular groove gradually increase with the increase of the radius of the annular groove. The bottom of the annular groove is provided with several through holes, and the diameter of the through holes increases with the increase of the width of the annular groove. A recovery tank is provided under the supporting device, and a telescopic device is provided on the left side of the recovery tank. The upper end of the telescopic device is connected with a connecting rod, and the connecting rod is connected with a pressure plate located directly above the receiving device. The shape and size of the lower surface of the pressure plate are consistent with the shape and size of the upper surface of the accommodating device. The present invention can satisfy the demand for shell breaking of nuts, can also classify nuts, save working time and manpower, and can make full use of the economic value of nuts to bring more economic benefits to users.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a rotary nut shell breaking machine. Background technique [0002] Nut shelling machines usually have stamping type and pressing plate type. The stamping shell breaking uses a punch and a mold to punch the nuts with a certain pressure and spacing, so as to achieve the purpose of breaking the shell. The pressure plate type uses two parallel steel plates to squeeze each other to break the shell. The existing nut shelling machines have the disadvantages of non-adjustable spacing, slow speed, a large amount of manpower assistance, low effect and efficiency of cracking hard shells, and unsatisfactory nut integrity rate. In terms of nut grading, the existing technology uses a graded barrel-shaped screen with holes of different diameters on it, and rotates the screen barrel to achieve the purpose of grading. This kind of equipment has the disadvantages of high energy consumpti...

AI Technical Summary

Problems solved by technology

The existing nut shelling machinery has the disadvantages of non-adjustable spacing, slow speed, and the need for a large amount of manpower assistance. The effect and efficiency of breaking hard shells are relatively low, and the integrity rate of nuts is not ideal.

In terms of nut grading, the existing technology is to use a graded barrel-shaped screen with holes of different diameters on it, and rotate the screen barrel to achieve the purpose of grading. During the process, it is easy to cause the problem that the nuts block the screen holes

[0003] In the prior art, two different equipments are often used for grading and shelling of nuts. When shelling ungraded nuts is simply cracked with a shelling machine, due to the difference in the diameter of the nuts, the crushing is uneven and the crushing efficiency is low.

When using the method of grading first and then cracking the shells to process nuts, the nuts need to be graded and cracked separately. Due to the use of two sets of equipment, the energy consumption increases and the equipment installation takes up a lot of space, which brings many problems to production and use. inconvenient
