Abstract

PURPOSE:To obtain the title device capable of removing a large amount of shell of boiled eggs in a short time, having greatly improved hygienic aspect, including a process of pushing boiled eggs from above by a press machine under such pressure as to crack only shell at the outer periphery part at the central position. CONSTITUTION:Boiled eggs 1 transported side by side by a conveyor with blades are pushed at the outer periphery part of the central position from above by a press machine 2 under pressure to crack only shell, then the boiled eggs 1 are sandwiched in the longer direction by adsorption pats 3 in a state of shell of the boiled eggs 1 adsorbed from both sides by one-fourth of the boiled eggs, the adsorption pats 3 are rotated left and right reversely while jetting water 6 toward the central position of the cracked shell 5 of the boiled eggs 1 by a high-pressure nozzle 4 and the shell is separated outside to give the objective device.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field This invention relates to a device that can fully automatically remove the shells of boiled eggs.

(b) Conventional technology Conventionally, there was no other way to peel a boiled egg other than to peel it by hand, which was very time consuming and difficult.

Q9 Problems to be solved by the invention This invention provides a hygienic device capable of continuously peeling boiled eggs in a short period of time for the catering lunch box industry where it is necessary to peel a large quantity of boiled eggs. With the goal.

B) Means for Solving the Problems An embodiment in which the present invention is implemented as an automatic boiled egg shell removal device will be described below with reference to the drawings.

The first figure shows a shell-breaking part that breaks the shell of a boiled egg and a mechanism that separates the shell from the egg body.

Boiled eggs transported in parallel by a conveyor with blades (
1) From above, press the outer periphery of the central position with a press machine (2) with enough pressure to break only the shell, and in the next step, press the boiled egg (1) in the longitudinal direction with a suction pad (3). Boiled eggs (1℃
After holding each shell with about a quarter of it adsorbed from both sides, use a high-pressure nozzle /l/(4) to spray water (6 ) This is an automatic boiled egg shell removing device that rotates the suction pad (3) in the left and right directions and pulls it outward while fully injecting the eggs.

((e) Function) Since the present invention is the above-mentioned device, the work of breaking the shells (5) with the press machine (2) from above the boiled eggs (1) that have been conveyed in parallel by the conveyor with blades is done by humans. This is the result of focusing on the process of peeling the shell of a boiled egg by hand.In boiled eggs, the main body of the boiling dish, the shell, and the thin skin in between protect the dish, so when peeling the shell, If the shell is in close contact with the dish body (7) in a near-vacuum state, making it difficult to work with, a human's hand may hit the shell on the desk to remove the shell (7).
The reason why the shell is damaged when the thin skin is in close contact with 7) is that the damaged state of the irregularly shaped shell creates a gap between the boiling dish body (7) and the thin skin, and the close contact is broken and the shell is broken. The press machine (2) mechanically creates a condition that makes it easier to peel the egg shells, making it possible to work continuously.

In the next continuous process, the outer periphery of the boiled egg (1) at the central position is removed from the boiled egg (1) that has been damaged by the press (2).
After holding the eggs in an adsorbed state with suction pads (3) from both sides in the longitudinal direction, water (6) is applied to the center of the shell (5) of the boiled egg (1) using a high water pressure nozzle (4). When the water is spouted, water (6) is injected into the gap created by the shell (5) splitting.
, the boiling dish body (7) and the cracked shell 6) are separated from the close contact state, and the cracked shell (5) is blown away by the high pressure water (6), making it easy to separate the shells (5) from side to side. Then,
The remaining shell (5) can be peeled off from both sides by rotating the adsorption para (3) that is pinched from both sides in opposite directions and pulling it outward.
7) It becomes something that can be taken out.

(f) Example If the tip of the pressing machine (2) that fully presses the boiled egg (1) has a shape close to the outer semicircle of the boiled egg (1), the area at the center where the shell (5) breaks can be reduced. In many cases, if the receiver is placed on a conveyor with blades that serves as a plate so that the protruding part touches the bottom center of the boiled egg (1), the press machine (2)
Needless to say, both the tip and the outer circumference of the boiled egg (1) press against the central outer circumferential part of the boiled egg (1), causing further damage to the shell (5) over a large area.

After the boiled egg main body (7) is taken out, the boiled egg main body receiver of the rotating cylinder is dropped onto the dish (8) and collected.
A simple device is sufficient for dropping the shell (5) portion onto a conveyor below and collecting it in a crusher.

(G) Effects of the Invention Since the present invention is a device as described above, it has the following effects.

Hygiene has improved dramatically since boiled eggs do not have to be touched by human hands as in the past.

A high water pressure nozzle removes and takes out the gold from the boiled egg body, which has a cleaning effect, removes impurities such as #I bacteria that are resistant to boiled eggs, and helps prevent boiled eggs from spoiling, resulting in the above effects. Together with this, the sanitary effect increases.

Since mass production using a belt conveyor is possible, large quantities can be supplied to the catering lunch box industry in a short period of time, and being able to process in a short period of time allows us to provide consumers with the most important freshness of food. It has the effect of becoming a thing.

Since all of the shelling work is done by machines, there is no need to rely on the labor that was previously done by hand, resulting in a significant reduction in labor.
