Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to an apparatus for separating sandbags from citrus fruits such as tangerines, lemons, oranges, and grapefruits.

``Conventional technology'' Citrus fruits consist of an outer skin and a number of rings (
Each tassel is made up of a tassel skin (shonoha) and a number of sand sacs wrapped in this shonoha. The citrus sandbags are then separated into individual pieces and used for canned goods, desserts, juices, etc.

Conventionally, sandbag separation equipment for obtaining sandbags separated into individual sandbags consists of an acid/alkaline solution tank for removing the sandbag skin, a washing tank for washing the sandbags with water, and a sandbag separation system that removes the sandbags. Dispersion devices for individual separation are known. According to this separation device, the rind of the citrus fruit is first dissolved and removed in a solution bath, and the rind is made into an aggregate of sandbags. Next, the obtained aggregate of sandbags is thoroughly washed with water in a washing tank to remove adhering acid/alkaline solution, etc. After this, the aggregate of sandbags is boiled to weaken their mutual adhesion before being sent to a dispersion device.

Then, in the dispersion device, the sand is separated into individual sand bags by direct impact caused by stirring, indirect impact caused by water pressure, eddies, steam, etc.

``Problems to be Solved by the Invention'' Although such conventional sand bag separation devices can collect sand bags with a relatively good shape, they have the following disadvantages.

(1) Fruits are treated chemically using chemicals such as acid/alkaline solutions and washing water, so the treatment takes a long time and wastewater treatment costs a lot of money.

(2) Also, when this separation device is used to separate sandbags, the sandbags are further affected by heat in addition to the effects of chemicals, washing water, etc. Nutrients such as C are significantly lost.

(3) Furthermore, this separation device requires a large amount of labor because there are many locations that require manual labor.

"Object of the Invention" The present invention was made in view of the above circumstances, and includes
It is possible to separate sandbags from citrus fruits such as oranges, grapefruits, lemons, etc. in a short time without any heat treatment, chemical treatment, etc., and there is little loss of nutrients, there are no problems such as wastewater treatment, and it is labor-saving. The purpose of the present invention is to provide a sand bag separation device that can perform the following steps.

[Means for Solving the Problems] In the present invention, the sand bag separation device is equipped with a screw-type conveying means that stores a liquid refrigerant for rapidly freezing citrus fruits and conveys the fruits. A refrigeration device comprising a storage tank and an elevator-type conveyance means for conveying the fruit from the advancing end of the screw-type conveyance means of the storage tank toward a discharge port provided above the outside of the storage tank, and a refrigeration device for hitting and crushing the frozen fruit. The above-mentioned problem was solved by comprising a single-stroke impact device and a sorting device that sorts and takes out the sandbags that are separated into pieces from the crushed fruit.

``Operation'' When citrus fruits are put into this sandbag separation device, they are first rapidly frozen and solidified in a freezing device.

In this state, the sac becomes brittle and brittle, and the sandbags that grow densely within the sac become individually frozen and easily peeled off from each other.

The citrus fruits thus frozen are then sent to a single-stroke striking device and are struck once at a time. This blow destroys the canister of the frozen fruit and separates the sandbags that were enclosed in the canister.

Next, these destroyed canister skins and the like are separated from the separated sand by a sorting device, and the sandbags are taken out.

The first single-stroke striking device 2 and the second single-stroke striking device 4 strike the citrus fruit frozen in the freezing device 1 to crush the bunches of the fruit and break the rind into small pieces. At the same time, the sandbags that were wrapped in the sandbags are separated and removed individually.

The single-strike type impacting device referred to herein is a hitting device that applies an impact to the target fruit only once and does not repeatedly apply impact. It is desirable that the type and intensity of the impact applied by this striking device be adjusted as appropriate depending on the shape, size, and condition of the fruit to be struck.

Suitable for use in the separation device of the present invention. Examples of single-stroke impact devices include a shearing crusher 40 as shown in FIG.
A roller set crusher 41 as shown in FIG. Examples include a roller set crusher 42 as shown in FIG. 5 and a press crusher 43 as shown in FIG.

The shear type crusher 40 shown in FIG.
The rotating roller 47 has a plurality of protrusions 46 that engage with the uneven portions 44 of the fixed teeth 45 with gaps. This shearing type crusher 40 crushes fruits that have slipped onto the uneven portions 44 of fixed teeth 45 by hitting them with protrusions 46 of rotating rollers 47 and shearing them. This shear type crusher 40
is suitable for coarsely crushing fruits.

A roller set crusher 41 shown in FIG. 4 includes two rollers 49 and 49 facing each other and each having a large number of protrusions 48 on their surfaces.

Further, the roller set crusher 42 shown in FIG. 5 is provided with two opposing rollers 51, 51 each having a plurality of protrusions 50a and grooves 50b alternately formed along the axial direction. It is something.

In these roller set crushers 41, 42, the rollers 49, 49 or 51, 51 are rotated inwardly, and the loaded fruit is crushed by the opposing protrusions 48 or 50a. It separates sandbags by hitting them in a suppressive manner.

The press type crusher 43 shown in FIG. 6 includes a press hammer 54 provided on a belt conveyor 53 that drives an endless belt 52 in the form of a mesh or a flat plate. In this press type crusher 43, a belt conveyor 53
The fruits brought in are pressed with a press hammer 54 to separate the sandbags.

In the sand bag separator of this first embodiment, as shown in FIG.
0 is used, and a roller set crusher 42 is used in the second single-stroke impact device 4.

The first sorting device 3 and the second sorting device 5 connected to these single-stroke striking devices 2.4 are for sorting and taking out the sandbags separated by the single-stroke striking device 2.4. . These sorting devices 3.5 include a so-called sieving device,
Various types of devices can be used, such as a wind-force sorting device that uses the power of the wind, a sorting device that uses swirling flow such as a cyclone, and a specific gravity sorting device that uses sedimentation or floating phenomena.

In the sandbag separation device of this first embodiment, as shown in FIG. 7, both the first sorting device 3 and the second sorting device 5 are provided with a sieve 55. It is used.

The sieves 55 of these sorting devices 3.5 have appropriate holes corresponding to the body diameter of the sandbags to be sorted. In the sorting device 3.5 of this example, the sieve 55 is vibrated at an appropriate frequency and amplitude, and precessed at an appropriate rotational speed and angle.

Next, the operation of this sand bag separation device will be explained.

First, in operating the apparatus, liquid refrigerant is supplied from the refrigerant supply pipe 21 to the storage tank 6 of the refrigeration apparatus I.

The height of the liquid level 22 of this liquid refrigerant is kept constant by a liquid level detector 23. In this refrigeration system 1, since the discharge port 10 is installed at a higher position than the storage tank 6, the liquid level 22 of the refrigerant boule 13 can be set high, and a large amount of liquid refrigerant can be stored.

Further, in this refrigeration system I, the discharge port 15 is provided at a high position, so that cold air is prevented from flowing out and loss of refrigerant is prevented.

Next, the citrus fruit is put into the freezing device 1 either as it is or after removing the outer skin. At this time, fruits may be added one by one, but the yield of sandbags is better if they are added in parts. The processed fruit falls from the chute 20 into the refrigerant boule +3 of the storage tank 6. Inside the housing 7, the screw 24 of the transfer means 8 is rotated by a drive 31, and the fruit in the refrigerant boule 13 is
The screw blades 27 of the screw 24 sequentially transport the liquid to the discharge port IO side. During this transfer the fruit is cooled or frozen. A large number of holes 30 are bored in the threaded blades 27 of the screw 24, and the liquid refrigerant can freely pass therethrough, thereby preventing entrainment of the liquid refrigerant as the fruit is transferred. Furthermore, this prevents the liquid refrigerant from being unevenly distributed to one side of the storage tank 6, thereby preventing a delay in the transportation of the fruit due to the backflow of the refrigerant caused by the uneven distribution of the refrigerant.

On the discharge port 10 side of the housing 7, an elevator 25 of the transfer means 8 is operated by a drive device 38, and the citrus fruits transferred to the discharge port 10 side by the screw 24 are sequentially transferred to the discharge port 10 by the packets 33 of the elevator 25. and sent to the first single-striking type striking device 2 through the discharge port IO. Since a drain hole 39 is formed in the packet 33 of the elevator 25, the liquid refrigerant is removed while the citrus fruits are carried up by the elevator 25, and loss of the liquid refrigerant due to the packet 33 is prevented.

In addition, in the refrigeration system of this example, the screw sleeve 26 of the screw 24 also serves as the rotation axis of the sprocket 34.34 below the elevator 25, so the bearing mechanism of the sprocket 34.34 is simplified. Housing 7
The internal structure can be simplified.

When freezing citrus fruits using freezing device 1, the product temperature is 150.
It is desirable to keep the temperature below ℃.

If the product temperature exceeds -50° C., the sandbag will not be sufficiently frozen and solidified, and the sandbag will be easily damaged by the impact from the single-stroke impact device 2.4. Furthermore, freezing in the refrigeration/freezing device 1 is as follows:
It is desirable to do this rapidly to maintain the freshness of the sandbag. For citrus fruits frozen in this way, the peel,
The sandbags and the albedo that bind them together have become brittle, and the sandbags wrapped in the sandbags have been frozen individually, making them easy to separate from each other. There is.

The citrus fruits thus frozen in the freezing device 1 are sequentially fed onto the fixed teeth 45 of the shearing type crusher 40 forming the first single-stroke impact device 2. The fruit placed on the fixed teeth 45 slides on the fixed teeth 45, reaches the uneven portion 44, and is struck by the protrusions 46 of the rotating roller 47. This blow shatters the clusters of citrus fruits, crushes the bark, and releases most of the sand sacs that are enclosed in the bark. The citrus fruit processed in this way by the first single-stroke impact device 2 becomes small pieces of camphor skin and individually separated sand sacs, but some of these are incompletely crushed. There are also some uncrushed bunches.

The citrus fruits that have passed through the first single-stroke striking device 2 in this manner are sent to the first sorting device 3. First sorting device 3
Then, the fragmented yeast skin and uncrushed bunches and the individual sand bags are sieved and collected. At this time, since the sieve 55 of the first sorting device 3 is precessed, the sandbag rises vertically in the length direction on the sieve 55 and passes through the sieve 55 in an upright state. In this way, sandbags are sorted efficiently.

Fruits that cannot pass through the sieve 55 of this first sorting device 3 are
It is sent to the second single-striking type striking device 4 for further striking. This second single-striking striking device 4 includes a runner 42 with a set of rollers.
The uncrushed bunches etc. thrown in between the rollers 51.51 are
It is hit with pressure by .... As a result, the sandbags and the like are broken into small pieces, and the remaining sandbags are separated.

The materials processed by the second single-stroke striking device 4 are sent to the second sorting device 5 and sorted again.

The sand sacks sorted by the second sorting device 5 are combined with the sand bags sorted by the first sorting device 3, and the sandbags, which are slightly mixed in, are collected by an appropriate wind sorting device, etc. Small pieces and other impurities are removed and the product is made into a product.
