A liquid egg pasteurization system

Abstract

The invention discloses a pasteurization system for an egg liquid and belongs to the technical field of automatic production. The system mainly comprises a combined heat exchange plate, a thermal insulation coil, a heating accessory, an energy recovery accessory, a power pump and a pneumatic valve bank. An enclosed pure water circulation system is adopted in the system, so that the defect of potential safety hazards caused by direct heat exchange between cold and hot materials in a traditional energy recovery unit is avoided; the flow direction of a cleanout fluid in the heat exchange plate can be adjusted by changing the on-off state of a pneumatic valve; and positive and reverse cleaning of the heat exchange plate is realized. In addition, small-cycle repeated sterilization on the material in a plate preheating section, a heating section and a thermal insulation pipe can be realized under the exceptional circumstance that the sterilization effect of the sterilized egg liquid does not meet the requirements; the condition that the product reaches the set sterilization effect is ensured; and a pre-cooling section and a cooling section behind the thermal insulation pipe are prevented from being polluted during abnormal sterilization.

Description

technical field [0001] The invention relates to a liquid egg pasteurization system, which belongs to the technical field of automatic production. Background technique [0002] The egg pasteurizer is the most critical equipment to ensure product quality in the whole egg processing. Due to the high viscosity of the egg liquid, it is sensitive to temperature, and the egg liquid also contains egg membrane silk and other substances, and a pasteurizer must be able to process egg yolk liquid and protein liquid , Whole egg liquid and egg liquid with salt and sugar are completely different in nature of egg liquid raw materials, so there are very special and strict requirements for egg killing machine. [0003] At present, the existing pasteurization units mainly include plate type sterilization unit and tube type sterilization unit. Among them, the plates of plate type sterilization unit are easy to block, not easy to clean thoroughly, and the continuous sterilization time is limited...

Problems solved by technology

[0003] At present, the existing pasteurization units mainly include plate type sterilization unit and tube type sterilization unit. Among them, the plates of plate type sterilization unit are easy to block, not easy to clean thoroughly, and the continuous sterilization time is limited, which affects production efficiency; tube type sterilization unit The structure is complex, not suitable for processing high-viscosity materials, and it is difficult to process egg yolk liquid, egg white liquid, whole egg liquid and egg liquid with salt and sugar with completely different properties on one pasteurization machine
