Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for peeling citrus fruits such as summer mandarin oranges, Igeta mandarin oranges, Satsuma mandarin oranges, and other oranges.

Mandarin oranges have a hair-like inner skin (cuticle) inside the outer skin (foreign skin), and inside that, the pulp is divided into multiple pieces radially in a cyst (a cyst).
It is contained in the fruit sac (carp/carp).

The conventional method of peeling mandarin oranges is to boil the mandarin oranges in advance and then manually peel them with a bamboo spatula, which is time-consuming and time-consuming.
It was a time-consuming and tedious task.

There is also a machine that peels the skin as an alternative to this bamboo spatula, but the inner skin adheres to the cyst and the outer skin and inner skin cannot be peeled off properly, and only about 60 to 70% of the skin can be peeled to a satisfactory degree.

Moreover, since a bamboo spatula and a machine are used, there is a drawback that the cyst and pulp are easily damaged.

In addition, as a method of peeling the skin by jetting water,
It is known that high-pressure water is sprayed from the outside of the onion, as in Japanese Patent No. 17391, but if high-pressure water is simply sprayed closely from the outside of the onion, the outer skin and cysts will be strongly damaged by the cilia of the cuticle (inner skin). It was difficult to peel the bound mandarin oranges.

The present invention solves these drawbacks and difficulties, and is based on a new and highly practical concept that allows the outer skin and inner skin to be peeled quickly and reliably, without damaging the cyst or pulp, and eliminating the need for boiling. The purpose of this invention is to provide a method for peeling an orange.

In the present invention, mandarin orange 1 may be boiled in advance or may not be boiled.

A predetermined size of the tangerine outer skin on the opening side or navel side of tangerine 1 is cut off using appropriate means (see FIG. 1).

If necessary, a water spout may be provided in the outer skin portion on the opposite side of the cut out opening 2.

Next, a high-pressure water injector 6 as shown in FIG.
High pressure water of grade A or lower is injected between the cyst 4 and the inner skin 5 or outer skin 3.

The injected high-pressure water passes between the cyst 4, the inner skin 5, and the outer skin 3 while being pushed apart by water pressure. During the passage, the water pressure of the water flow or the water pressure of the water stored in the outer skin 3 is applied to the cyst 4 and the outer skin 3. Pressure is applied between the inner skin 5 and the outer skin 3 in the direction of separating them, so that the outer skin 3 and the inner skin 5 are surely peeled off from the cyst 4 while the inner skin 5 remains attached to the outer skin 3.

The peeled outer skin 3 and the inner skin 5 are easily peeled off by the pressure of high-pressure water or other auxiliary skin removal means.
, the endothelium 5 is separated and removed from the cyst 4, and the orange 1 is removed from the cyst 4.
Only the pulp part that fits within the area is left.

In addition, in the diagram of the high aqua regia injector 6 shown in FIG. 2, 7 is the container body;
8 is a high-pressure water storage, 9 is a high aqua regia hose, 10 is a plurality of injection nozzles provided radially, 11 is a hard skirt, and 12 is a spring.

The example shown in FIG. 3 is another example showing a peeling method using high-pressure water, in which the high-pressure water is sprayed from an annular outer skin cutting groove 15 provided in the body of the orange 1 to remove the outer skin 3, inner skin 5, and cyst 4. The water passes between the two and is discharged from the discharge ports 13.
This method involves separating the cyst from the cyst 4 and peeling the skin.

As described above, according to the present invention, by using high-pressure water and peeling off the outer skin 3 and inner skin 5 under the pressure, the skin can be quickly and reliably peeled without damaging the pulp part that fits in the cyst.
This method has the advantage that the peeling work of mandarin oranges can be performed extremely efficiently, and the mandarin oranges do not require boiling, and the quality of the mandarin oranges is excellent.

Claims (1)

[Claims] 1 Cut out the orange peel part at the navel or navel of the orange 1 to a predetermined size to create an opening 2, then insert a high-pressure water sprayer 6 into the opening to spray high-pressure water between the peel 3 and the cyst 4 or Water is injected between the endothelium 5 and the cyst 4 from the opening 2 while keeping it watertight so as not to leak, and the water pressure of the high-pressure water passing between the outer skin 3, the endothelium 5, and the cyst 4 is used to remove the outer skin 3. , a method for peeling an orange, characterized by separating the endothelium 5 from the cyst 4.
