Description

The invention relates to devices for breaking a large number of eggs and separating yolks from proteins and can be used in the food industry.

A known machine for breaking eggs and separating their contents. The machine includes a chain roller transport and a conveyor belt on which the knots for breaking eggs are rigidly mounted. Each of the nodes contains a base, two paws for receiving the egg, a spring-loaded swivel clamp for fixing the egg, and two spring-loaded knives aligned with the blades mounted on the same axis as the legs, and a mechanism for opening the legs, made in the form of a cam mounted on the same axis as the clamp for fixation of the egg, and is equipped with a stop with a handle and a roller mounted for rotation and interaction with the legs. Knot

an egg separation separator (separator) is mounted under the breaking assembly and includes a protein cup having a hemispherical recess in the center and coaxially mounted, in a recess on the bracket, a yolk cup. At the loading position there is a shell-discharge mechanism comprising a tray and a plate stop; trays for collecting products and shells are installed.

The disadvantages of this machine are the complexity of the design of the mechanism for opening the legs of the breaking unit, where the impact (opening and mixing) on the legs is produced from the machine copier through an additional device in the form of a cam equipped with a roller, and unproductive loss of protein accumulating between the shell and the knives, because the breaking unit is rigidly installed in the conveyor (does not have

rotation options for pouring protein).

These disadvantages are eliminated in the machine for the extraction of egg contents and its separation, described in US patent Ns 4321864, N.CL, 99-500 from 03.30.82. The machine contains a loading device, a closed conveyor, on which the breakdown nodes are pivotally mounted with mounted below them separators controlled by the copier system. The breaking unit comprises a base on which two spring-loaded tabs are articulated. The paws are parallel and have a bend for receiving the egg. A spring-loaded blade of a knife is hingedly mounted on each foot in the bending zone. A spring-loaded clamp for fixing the egg is also pivotally mounted on the base, and a pusher interacting with the copier is rigidly fixed. The breaker is much simpler and more reliable than its counterpart, due to the hinged fastening of the assembly on the conveyor and the possibility of rotation, the accumulation of protein between the shell and the knives is prevented.

The separator is made in the form of two cups pivotally mounted on a common base, which is mounted on the conveyor. The cups are aligned, the top is for the yolk and has an opening through which protein flows into the bottom cup,

The process of breaking the egg and separating its contents is carried out by turning the conveyor in the discharge zone, the yolk and protein are separately poured into the appropriate containers, and the shell is blown off by air from the nozzles into a special tray.

However, when the egg is automatically loaded, when it rolls into the paws of the breaker assembly of the rotating conveyor, cases of incorrect egg orientation, i.e. its major axis is inclined. In this case, the shell is broken unevenly with a knife, destruction of the yolk by a knife is possible, while a smaller fragment of the shell is not fixed by pressure, falls into the separator cup, and the destruction of the yolk is also possible (see Fig. 5). In addition, a portion of the protein adhering to the walls remains in the shell, i.e. the yield of the product is reduced.

An object of the invention is to more fully extract the contents of eggs.

This goal is achieved by the fact that in the machine for extracting the contents of the egg and its separation, comprising a loading conveyor, a rotor with pivotally mounted separation nodes, each of which includes a clamp, a vertically mounted breaking mechanism, mounted to interact with the copier fixed to the rotor coaxially having sections of loading, orientation, separation, breaking and unloading, and a separator, vertical corrugations are made on the copier located on the sections oriented and and sharing the contents of it.

Performing the copier corrugated in the orientation zone allows you to set the egg in the legs horizontally with a large axis due to the vibration of the breaking unit and the egg self-installation, i.e. guaranteed to provide high-quality egg breaking, eliminates the destruction of the yolk. Making the copier grooved in the separation zone by vibration allows the protein to be more fully ejected from the shell, thereby increasing the protein yield.

In FIG. 1 shows a general view of the machine; in FIG. 2 - sequence diagram of the machine; in FIG. 3 - a breakdown and separator assembly in the egg orientation zone B; in FIG. 4 - wrong orientation of the egg; in FIG. 5 - a notch and a shell break with an incorrect orientation of the egg; in FIG. 6 - correct orientation of the egg; in FIG. 7 - a notch and a break in the shell with the correct orientation of the egg; in FIG. 8 is a breaker assembly and a separator in a zone D for separating the protein from the yolk.

The machine for extracting the contents of eggs and its separation includes a frame 1 on which a loading conveyor 2 is mounted, a rotor 3 with separation units 4 mounted thereon, a drive 5, a copier 6 (FIGS. 1, 2) of an egg clamp, a copier 7 of a knife platoon , copier 8 lifting the breaking unit, copier 9 for moving the separator valve, cam 10 (Fig. 2) for spreading the legs and knives, cam 11 for combining the legs and knives, copier for controlling the separator and trays for collecting proteins, yolks and shells (not shown) . The separation unit 4 comprises a clamp 12 (FIGS. 1, 3, 8) fixedly mounted on the rotor 3, a breaker assembly 13 and a separator 14. The clamp 12 is a bracket 15 (FIGS. 3, 8) on which the axis lock 16 is mounted the hinge 17 of the breaking unit 13, the latch 18 of the axis of the hinge 19 of the separator 14, the latch 20 of the separator 14.

The breaking unit is made in the form of a bracket 21 with a pusher 22, paws 24, on which spring-loaded knives 25 are pivotally mounted, are pivotally mounted on the axis 23 of the bracket 21. A spring 27 is placed between the tabs 24.

Screws 28 serve to control the extension of the knives so as to prevent the yolk from breaking when the shell is cut. The clamp 29 (Fig. 1, 2, 3, 8). fixing egg in the legs 24 mounted on the bracket 21 and has the ability to rotate around the axis 30 under the action of the copier b. On the copier 8 (Fig. 2) between the zones of loading A, breaking B and unloading D in the orientation zones B and breaking D, corrugated overlays 31 are installed.

The separator 14 (Fig. 1,3,8) contains two cups 32 connected by a bracket. A valve 33 is mounted in the opening of the upper cup 32, which is mounted on the bracket of the separator 14 using the axis 34. Relative to which the valve 33 can move up and down under the action of the copier 9 (Fig. 1). The separator 14 is mounted on the bracket 15 and is able to rotate around the axis of the hinge 19 when unloading the yolk and protein in the receiving trays under the action of a control copier (not shown).

The rotor 3, receiving rotation from the drive 5. moves synchronously with the loading conveyor 2, and at the time of passage of the loading zone A, the egg from the conveyor rolls into the legs 24 (Fig. 1, 2) of the breaking unit 13. 8, the copier 8 lifted the clamp 29 upward, and the copier 9 lowered the knives 25 down. In FIG. Figure 4 shows an embodiment of the position of the egg in the legs when its major axis is inclined. In the orientation zone B, the pusher 22 (Fig. 2) of the breaking unit 13, which is in contact with the corrugated plate 31 mounted on the copier 8, transmits vibration to the tabs 24, under the influence of which the egg self-aligns with the major axis horizontally (Fig. 6). Next, the spring-loaded clip 29 comes off the copier 6 and fixes the egg in the legs 24 (Fig. 2). With further rotation of the rotor 3, the separation unit 4 enters zone B, where the spring-loaded knife 25 breaks off the copier 7 and cuts the shell, and the cam 10, turning around the axis 23, spreads the legs 24 and knives 25, which break the shell (Fig. 7).

the yolk enters the valve 33, and the protein into the upper cup 32 of the separator 14. Next, the separation unit 4 enters the separation zone G (Fig. 2), in which the pusher 22 of the breaking unit 13 interacts with the corrugated plate of the copier 8, which creates a vibration of the breaking unit 13, providing a more complete separation of the protein from the shell and the flow of protein into the upper cup. At the same time, the lever 35 (Fig. 1, 8) interacts with the step copier 9, and the valve 33 moves up and down, opening and closing the hole in the upper cup 32 of the separator 14, through which the protein flows into the lower cup 32. Then, the separation unit 4 enters in the area D (Fig. 2) unloading. The control copier (not shown in the drawing) releases the separator 14 from the latch 20, and it rotates around the axis of the hinge 17, pouring the yolk and protein into the corresponding trays (not shown in the drawing). Further, in zone E, the clip 29 along the copy 6 rises up, freeing the shell: which is blown off by air from the pneumatic cutters into the receiving tray (not shown in the drawing). In the And zone, preparation for loading takes place: the knives 25 are cocked with the copier 7 and the tabs 24 are brought together with the cam 11. The separation unit 4 takes its initial position and the cycle repeats.
