Problems solved by technology

Based on this, it is judged that the main reason for the unsatisfactory cleaning effect is that the effect of alkali cleaning is not obvious.
[0007] For the second problem in the cleaning process of the ultra-high temperature sterilizer - after the alkali washing is completed, the shutdown of the homogenizer often occurs during the process of water pushing the alkali. The temperature is as high as 80°C. When encountering cold water, a large amount of foam will be generated, which will cause the liquid level sensor of the balance tank to send an error signal, resulting in the failure to replenish the softened water in time, resulting in no cleaning liquid in the cleaning circuit, and the homogenizer is running empty, which is protected by the program. automatic shutdown

Embodiment 1

[0017] Embodiment 1: as shown in Figure 1, the ultra-high temperature sterilization machine cleaning process includes the following process steps,

[0018] (1) First, add the cleaning media: water, alkaline water, water, acid water, and water to the balance tank in sequence;

[0019] (2), each medium enters the balance cylinder, preheating degassing device, high temperature sterilization device, cooling heat exchanger, homogenizer, and finally returns to the balance cylinder through the pipeline;

[0020] (3) Steam enters the steam-water mixer to heat the water in the hot water circulation system. The hot water circulation system then heats the temperature of the high-temperature sterilization device and the preheating degassing device. The hot water in the hot water circulation system is heated in the high-temperature sterilization device, Continuous circulation between the preheating degassing device and the steam-water mixer; by controlling the opening of the steam control ...

[0024] (2), each of the mediums enters the balance cylinder, preheating degassing device, high temperature sterilization device, cooling heat exchanger, homogenizer, and finally returns to the balance cylinder through the pipeline;

[0025] (3) Steam enters the steam-water mixer to heat the water in the hot water circulation system. The hot water circulation system then heats the temperature of the high-temperature sterilization device and the preheating degassing device. The hot water in the hot water circulation system is heated in the high-temperature sterilization device, Continuous circulation between the preheating degassing device and the steam-water mixer; by controlling the opening of the steam ...

Embodiment 3

[0027] Embodiment 3: as shown in Figure 1, the ultra-high temperature sterilization machine cleaning process includes the following process steps,

[0028] (1) First, add the cleaning media: water, alkaline water, water, acid water, and water to the balance tank in sequence;

[0029] (2), each of the mediums enters the balance cylinder, preheating degassing device, high temperature sterilization device, cooling heat exchanger, homogenizer, and finally returns to the balance cylinder through the pipeline;

[0030] (3) Steam enters the steam-water mixer to heat the water in the hot water circulation system. The hot water circulation system then heats the temperature of the high-temperature sterilization device and the preheating degassing device. The hot water in the hot water circulation system is heated in the high-temperature sterilization device, Continuous circulation between the preheating degassing device and the steam-water mixer; by controlling the opening of the steam ...

Abstract

The present invention discloses a cleaning process of ultrahigh temperature sterilizing machine. It is characterized by that the caustic washing temperature of high-temperature sterilizing device is controlled at 90deg.C-110deg.C, and the caustic washing temperature of balance cylinder is controlled at 50deg.C-70deg.C.

Description

Technical field: [0001] The invention relates to a cleaning process for an ultra-high temperature sterilizer. In particular, it relates to a cleaning process for an ultra-high temperature sterilizer specially used for liquid milk production. Background technique: [0002] The main parts of the ultra-high temperature sterilizer include: balance cylinder, preheating and degassing device, high-temperature sterilization device, cooling heat exchanger, homogenizer, steam-water mixer, hot water circulation pipeline and cold water circulation pipeline. The hot water circulation pipeline, the cold water circulation pipeline and the cleaning pipeline are completely isolated, and there is only a heat exchange relationship between them, and there is no interconnection on the pipeline. Among them, the balance cylinder, preheating and degassing device, high temperature sterilization device, cooling heat exchanger and homogenizer are connected in sequence through cleaning pipelines. A s...
