Poultry egg preboiling centering method and poultry egg preboiling centering machine

Abstract

The invention discloses a poultry egg preboiling centering method and a poultry egg preboiling centering machine. The method comprises the following steps of forwards conveying poultry eggs onto an egg plate; enabling the poultry eggs to enter hot water being 70 to 85 DEG C; soaking 1 / 2 to 2 / 3 of the poultry eggs by the hot water; pushing the poultry eggs in the hot water; enabling the poultry eggs to be in contact with the egg plate in the pushing process and to roll through receiving the friction force; steaming and boiling the poultry eggs in the hot water for 2 to 3 min; then, enabling thepoultry eggs to leave away from the hot water; and completing the poultry egg preboiling centering. The poultry egg preboiling centering machine comprises a machine frame, upper egg conveying equipment, preboiling centering conveying equipment and a water tank, wherein the upper egg conveying equipment, the preboiling centering conveying equipment and the water tank are arranged on the machine frame. The poultry egg preboiling centering method and the poultry egg preboiling centering machine provided by the invention have the advantages that the hot water is used for directly steaming and boiling the poultry eggs; the hot water is directly in contact with the poultry eggs and always covers the poultry eggs, so that the heating efficiency is high; and the water consumption is very low. Inaddition, the poultry eggs continuously roll and move in the preboiling process; the yolks can be enabled to be always in the centers of the poultry eggs; and the centering effect is good.

Description

technical field [0001] The application belongs to the technical field of poultry egg processing, and in particular relates to a poultry egg precooking and centering method and a poultry egg precooking centering machine. Background technique [0002] At present, the poultry and egg packaging industry needs to do a centering treatment for the eggs first. The egg centering treatment is to heat the eggs to reduce the fluidity of the egg white and egg yolk, so that the egg yolk of the egg is placed in the center of the egg to prevent the egg from being exposed when peeling. yolk. After rest assured, the eggs are in a half-cooked state, and follow-up processing is required to cook the eggs. For example, in the packaging of marinated eggs, the eggs need to be pre-centered, mainly because the yolk of poultry eggs will float up and finally touch the shell when the eggs are placed in a fixed state, so the yolk is exposed when the eggs are cooked and peeled. It sticks to the eggshell...

AI Technical Summary

Problems solved by technology

However, there is a very serious problem in this centering method. Since the specific gravity of poultry eggs is close to that of water, during the centering process, poultry eggs are affected by the buoyancy of water and float on the water surface, only partly in contact with water, and are unevenly heated. , it is very easy to cause partial heating and solidification, and it is impossible to achieve centering

Therefore, this technology has not been widely used in actual production.
