DD265797A1 - DEVICE FOR SEPARATING THE YELLOW FROM THE EIWEISS BY VACUUM - Google Patents

Abstract

The device for separating the egg white from egg yolk by means of vacuum is intended primarily for continuous egg whipping and cutting machines. The invention is based on the principle that the Eiinhalt is intercepted in a funnel-shaped separator and the protein is sucked out of the hopper by means of vacuum, while the egg yolk remains on the egg yolk shell located in the hopper. With appropriate design of the egg yolk shell, the egg yolk is also sucked by vacuum. The vacuum achieves a fast and effective separation and produces protein and yolks with a high purity factor. The handling of the separated egg components is done in a closed, veterinary hygienic system. With a suitable attachment of several separating funnels on a egg-wrapping machine, the process of protein and egg yolk production in a closed system can be largely automated. The device for separating egg whites and egg yolks is shown in FIG.

Field of application of the invention

The invention relates to a device for separating the egg yolk from the egg yolk by means of vacuum, which can be used in all egg processing establishments where manual or mechanical production of protein and egg yolk products takes place. The device is predominantly intended for continuous egg whipping and separating machines.

Characteristic of the known technical solutions All previously known solutions for separating protein from egg yolk are based on the same basic principle.

characterized in that after d6m open the egg egg content is trapped in a separating device, the egg white flows under the action of its own gravity through a separating gap and is thus separated from the egg yolk.

After the structural design, the known separation devices can be divided into two groups. The first group includes dio echalenförmigen separation devices, in connection with the corresponding Impact devices are suitable for the separation of individual Eilnhalten. In DT1920390 (1969) A47 J 43/14 a self-separation device is described. This consists of a trapping tray with a movable egg yolk shell and a receiving tray arranged thereunder

for dos separated protein.

When lifting the egg yolk shell from the seat of the interceptor creates an annular gap, causing the protein in the lower Tray drains and the egg yolk remains in the egg yolk shell. The separation process is performed by a mechanical

accelerated and completed forced movement of egg yolk shell.

U.S. Patent 4,137,837 (1977), U.S. Patent 3,480,056 (1969), U.S. Patent 3,455,356 (1965) and DT 2635072 (1976) are similar Separators boschrieben that differ only in the shape of the outlet gap. The other group includes separators having the shape of a gutter and one or more Own separation column. The egg contents are trapped behind each other in the upper part of the inclined gutter. In the Downward movement, the protein flows through the separation column in a gutter and is thus separated from the egg yolk. Such separation channels are described in DE-OS 2330244 (1973), DE-OS 2703152 (1977) and DD 223632 (1983) A47J43 / 14. The common disadvantage of both types of Trennvorrlchtungen is that the separation by gravity alone

he follows. As a result, in the relatively short residence time in the separator, especially in fresh eggs with viscous

Protein, no high degree of separation can be achieved. It is desired as perfect as possible separation, since the yolk

has a higher commercial value, which increases with increasing purity factor. The measures to improve the

Separation in the mentioned separation devices, such as forced movement of the shells or extension of the separation channel,

can damage the egg yolk.

From a veterinary point of view, the solutions mentioned don have the disadvantage that the separated egg components in the open, of

Gravity is used to transport the gutter system, which is not protected against external contamination, into the collection vessels.

The mentioned disadvantages can be eliminated by the present proposed solution. Aim of the invention

The aim of the invention is to accelerate and complete the separation of the egg white from the egg yolk and thus to achieve a high degree of separation for both products.

Another objective is to transport the separated yew plant from the separation device to the collection vessels in a closed system protected from external contamination.

Explanation of the essence of the invention The stated objectives are achieved by the use of vacuum. The Eiinhalt is intercepted after the impact in a funnel-shaped separator, which has a centrally mounted Egg yolk shell in the size of an average egg yolk. After a visual quality control of the egg, the separator is placed under vacuum. The egg white flows under

the effect of disappointing by the pressure difference ends forces, and is thus from remaining in the egg yolk shell

Egg yolk separately. The fact that the forces caused by pressure difference act in the same direction with gravity, results

nine reinforced, fast and complete separation.

The speed and integrity of the separation also depends on the age and temperature of the egg

existing pressure difference. The separated protein and optionally also the egg yolk can also be transported by vacuum in a closed pipe system in the collection vessels.

exemplary The invention will be explained below with reference to an example. Figure 1: Principle of separation by means of vacuum Figure 2: possibility for the permission of the separating funnel FIG. 3 shows an example of the arrangement of separating funnels on an egg breaking and separating machine The principle of separation of egg white from egg yolk by means of vacuum is shown in FIG. 1 dargobtellt.

The egg contents trapped in the funnel (1) are separated into egg yolk and egg white under the influence of vacuum in the funnel tube, with the aid of the egg yolk shell (2) fixed in the funnel. The separation takes place in that the protein is sucked through the annular gap between the hopper (1) and egg yolk shell (2) by means of the vacuum in the funnel tube. The yolk remains on the egg yolk shell (2). The protein can be sucked with the help of the vacuum into a collection container. The yolk can at sw. kbar stored hopper (1) can be dumped.

FIG. 2 illustrates a possibility for the design of the funnel which functions according to the explained principle. In this case, a removal by vacuum is also provided for the separated egg yolk. For this purpose, after the suction of the protein from the funnel (1) through the tube "a" and the tube "b" placed under vacuum. Thereby, the egg yolk is sucked out of the egg yolk shell (2) through the opening (3) and through the tube "b" into a collecting container which is provided for the egg yolk The shape and dimensions of the funnel (1), the egg yolk shell (2), The opening (3) and the pipes "a" and "b" should be chosen so as to minimize the risk of blockage of the separator due to membrane skin residue, hailstones, etc. In order to prevent clogging, the suction pipes can be supplied regularly, automatically be rewound pivoted disconnector.

FIG. 3 shows an example of the arrangement of the separating funnels illustrated in FIG. 2 on an egg-whipping and separating machine. The egg whipping mechanism is located in the upper area "c" of the machine The impact members (not shown) are mounted so that there is an impact member above each separating hopper so that the f.inha t can pass from the open Ef Into the separating funnel Separation means (4) are mounted on the o-axis of a bogie (5) which rotates in the direction of the arrow together with the impact mechanism The rotation is transmitted by means of the sprocket (6) attached to the turntable (7). The turntable (7) slides on the surface of the piston (8), ensuring proper centering and sealing (not shown) .The turntable (7) serves as a receptacle for the segments (9) on which they pivot The flange (8) is mounted as a lid on a double-walled vessel (12) .In the middle of the flange (8) is the vacuum connection (11), whereby de r interior and via the connection opening (13) and the shell space of the jacketed vessel (12) can be placed under vacuum. The egg white from the separatory funnels (4) is sucked through the tubes "a." The egg yolk from the egg yolk shells (2) of the separating funnel (4) is transported through the tube "b" into the interior of the double-walled vessel (12). During the work coil in the inner and mantle space by automatic level control a minimum liquid level always be present.

The operation of a constructed as described Eiaufschlag- and -trennmaschine can be explained as follows. The feeding and the impact of the eggs take place in area D (section B-B). The individual egg contents each arrive in a separating funnel (4). In the control phase, the lines "a" and "b" are not connected to the jacketed vessel (12), i. H. the separating funnel (4) is not put under vacuum. Thus, in the separation funnel, a visual quality control of the entire Eilnhaltes done. On further rotation of the bogie (5), the line "a" is connected by the longitudinal gap (14) in the flange (8) with the jacket space under vacuum.Thus, the protein can be sucked into the mantle space.Thus the egg white is separated from the egg yolk. The separating funnel (4) remains under vacuum through line "a" until the longitudinal gap (14) ends. Then the line "a" is closed and through the longitudinal gap (15), the line "b" is placed under vacuum. Accordingly, the egg yolk from the egg yolk shell (2) is sucked into the interior of the double-walled vessel. At the end of the longitudinal gap (15), the separating funnel (4) is ready to receive the next egg contents in the area D.

In the case of a zers'.örten egg yolk or enjoyment unfit egg, the separating funnel (4) in dor control phase to the beginning of the longitudinal gap (14) can be manually or automatically swung (16). As a result, the suction lines .8 "and" b "remain closed, and the non-enjoyable egg contents can not get into the double-walled vessel (12). When the separating funnel (16) is pivoted, automatic cleaning and disinfection of the separating funnel, which is wetted by non-digestible egg contents, can be carried out either from the outside or through the suction lines "a" and "b" (cleaning not shown). In addition to the illustrated variant with flange (8) with longitudinal columns of the separation process can also be controlled by in the segments (9) built-in electric or pneumatic valves. Through the valves, the suction lines "a * and" b "can be individually controlled, which offers an automatic quality control method-Jie possibility of a far-reaching full automation.
