Description

Sunflower shelling flail block and sunflower sheller and sheller using same

The technical field is as follows:

the utility model relates to a sunflower shelling field especially relates to a sunflower shelling gets rid of the piece and uses this sunflower huller and peel machine of getting rid of the piece.

The background art comprises the following steps:

the sunflower seeds are rich in unsaturated fatty acid, multiple vitamins and trace elements, are delicious in taste and are a popular snack and edible oil source. In part of food processing industries, sunflower seeds need to be hulled and kernel-extracted, so that a sunflower huller can be used for production.

Currently, sunflower hullers are common in the market, for example, a chinese patent with a patent number ZL201621478574.0 discloses a sunflower hulling and hulling separator, a chinese patent with a patent number ZL202011195360.3 discloses a sunflower hulling system, hulling processes of the two sunflower husks all include that sunflower raw materials are sent to a throwing cylinder by a hoist for hulling, sunflower hulls are removed by boiling separation after primary hulling, the rest sunflower seeds and the sunflower raw materials without hulling enter a sieving machine (or a fine screening sieve) for further separation, sunflower seeds are collected as finished products, the sunflower raw materials without hulling are sent to the hoist for lifting again and enter the throwing cylinder for hulling treatment.

The huller disclosed in the chinese patent No. ZL201621478574.0 comprises a cross support, a throwing disc, a throwing block and a rotating motor, which are arranged in a throwing barrel, and the hulling principle is that raw material sunflower seeds sent by a distributor are fed into the throwing disc along a feed port at the top of the huller, the throwing disc is driven by the rotating motor to rotate, the raw material sunflower seeds are thrown outwards along the throwing block under the action of centrifugal force, thrown onto the barrel wall and then collided, so that the hull opening of the sunflower seeds is even divided into two petals, and hulling is realized; the huller disclosed in chinese patent No. ZL202011195360.3 has substantially the same structure and hulling principle as the huller disclosed in chinese patent No. ZL201621478574.0, and the above two hullers have the following problems:

Comparative example 1

This comparative example provides a huller 2, this huller 2 is used among the last generation sunflower huller of Bayankee mechanical manufacturing limited company of Bayankee Yongming machine house (ZL 201621478574.0 a sunflower hulling and peeling sorter) (the huller of ZL 201678574.0 and get rid of a section of thick bamboo 2.1), it is smooth to get rid of a 1 surface, huller 2 among the comparative example 1 compares with huller 2 among the embodiment 2, it is the same to get rid of a 2.1 size, the distributor 2.6 size is the same, motor 2.3 power is the same, it is the same to get rid of a 1 size, it is also the same to get rid of the quantity of piece 1.

A shelling experiment was performed using the sheller 2 of example 2 and the sheller 2 of comparative example 1, each sheller 2 fed 10kg of sunflower seeds at the same feed rate, and the hull and kernel of sunflower seeds and unshelled sunflower seeds (including unopened sunflower seeds and opened unshelled sunflower seeds) were collected and separated from the discharge port, and the weights of the collected materials were calculated and listed in table 1.

TABLE 1 shelling effectiveness statistics table

As can be seen from table 1, the sunflower seeds (whole sunflower seeds and crushed sunflower seeds) obtained in example 2 were 3.48kg, accounting for 34.8% of the sunflower seed input, while the sunflower seeds (whole sunflower seeds and crushed sunflower seeds) obtained in comparative example 1 were only 1.53kg, accounting for 15.3% of the sunflower seed input; in contrast, the sunflower peel and unshelled sunflower seeds separated in example 2 were 3.45kg and 3.04kg, respectively, and the ratio of the sunflower seed entry was 34.5% and 30.4%, respectively; the sunflower hull and unshelled sunflower seeds separated in comparative example 1 were 1.53kg and 6.90kg, respectively, and the ratio of the sunflower seed entry was 15.3% and 69.0%, respectively;

in addition, the whole sunflower kernel obtained in example 2 was 3.32kg, accounting for 33.2% of the sunflower seed material (yield), while the whole sunflower kernel obtained in comparative example 1 was 1.28kg, accounting for only 12.8% of the sunflower seed material (yield).

It can be seen that, when the huller 2 of the embodiment 2 is used for hulling sunflower seeds, the hulling efficiency is higher than that of the traditional huller 2, and the occupation ratio of the whole sunflower seeds is also higher, because:

1. the huller 2 is provided with the guide groove 1.2, after the sunflower seeds enter the huller 2, the sunflower seeds are evenly distributed by the distributor and enter a cavity between adjacent throwing blocks 1, the huller 2 rotates, the throwing blocks 1 are contacted with the sunflower seeds, the sunflower seeds enter the guide groove 1.2, the head or tail of the sunflower seeds face the throwing cylinder 2.1 due to the fact that the width of the sunflower seeds is equal to the width of the guide groove 1.2, the head or tail of the sunflower seeds are thrown out along the guide groove 1.2 under the action of centrifugal force, and the head or tail of the sunflower seeds impact the throwing cylinder 2.1 to break the hulls; and traditional flail piece 1 only can drive the sunflower seed outwards and get rid of, does not have the guide effect to the sunflower seed, and when the sunflower seed was got rid of on getting rid of section of thick bamboo 2.1, head, afterbody and belly all probably hit with getting rid of a section of thick bamboo 2.1, and the broken shell rate on the one hand is low during the belly striking, and on the other hand the sunflower seed is beaten the probability of smashing and is increaseed.

2. The inclined plane 1.3 is arranged on the huller 2, after the huller 2 enters a cavity between adjacent throwing blocks 1, the inclined plane 1.3 of the throwing block 1 is in contact with the sunflower seeds, the sunflower seeds can easily rise along the inclined plane 1.3, all the guide grooves 1.2 of the throwing blocks 1 can enter the sunflower seeds from bottom to top, and the thrown sunflower seeds are more uniform in height; and traditional throwing block 1 and sunflower seeds contact the back, and the sunflower seeds of throwing block 1 lower part pile up more, and the sunflower seeds of upper portion is less, is thrown away the sunflower seeds of back lower part and does not disperse, and the striking is thrown that the section of thick bamboo 2.1 back broken shell effect is poor, influences the shelling rate.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
