Embodiment 1

[0054] This embodiment provides a fluid delivery system. In one embodiment, as figure 1 As shown, the fluid delivery system includes a fluid delivery target, a fluid delivery source 11 .

[0055] Among them, the fluid delivery target includes a material cylinder 14 and a fluid output unit 15. The material cylinder 14 is connected with a first air intake control unit 1 and a feed valve 2, and the first air intake control unit 1 is suitable for controlling the feeding of sterile air into the material cylinder. , the fluid output unit 15 communicates with a cleaning return pipeline; the fluid delivery source 11 is provided with a feed valve 9, and the feed valve 9 is connected to the feed valve 2 through a feed pipeline; the feed pipeline is provided with the highest point 4, the highest The height of point 4 is higher than that of the feed valve 2, and there is a drainage branch connected between the feed pipeline close to the feed valve 2 and the cleaning return pipeline, and ...

Embodiment 2

[0072] This embodiment provides a control method using a fluid delivery system, and the control method is used in the fluid delivery system provided in Embodiment 1. In one embodiment, the control method includes the following steps:

[0073] S1: Discharge the water from the highest point 4 to the feed valve 2;

[0074] S2: Control the opening of the first air intake control unit 1 and the feed valve 2, so that the feed pipeline is filled with sterile air;

[0075] S3: Control the opening of the feed valve 9 and the top air discharge valve 3, so that the feed liquid in the fluid delivery source 11 enters the feed pipeline, and the feed liquid pushes the sterile air to be discharged through the feed top air discharge valve 3.

[0076] In this embodiment, the water in the feeding pipeline is discharged first, and the temperature of the feeding pipeline can be lowered during the process of filling the feeding pipeline with sterile air, thereby avoiding the impact of sterile hot ...

Embodiment 3

[0102] This embodiment provides a control method using a fluid delivery system, and the control method is used in the fluid delivery system provided in Embodiment 1. The difference between this embodiment and embodiment 2 is:

[0103] Step S1 includes: controlling the feed valve 2, turning on the cleaning return pump 13, and discharging the water from the highest point 4 to the feed valve 2.

[0104] In this embodiment, step S1 can drain the hot water in the second branch section by increasing the backflow delay function in the last link of cleaning and disinfection, without manual operation by the operator, and also realizes the manual operation error prevention function.

[0105] Specifically in this embodiment, the following steps are included:

[0106] Step S1: control the feed valve 2 and the cleaning return pump 13 to turn on, and discharge the water from the highest point 4 to the feed valve 2. Increase the time-delay function of reflux and evacuation after cleaning a...

Abstract

The invention relates to the technical field of food production, in particular to a fluid conveying system and a control method thereof. The fluid conveying system comprises a fluid conveying target and a fluid conveying source, the fluid conveying target comprises a material cylinder and a fluid output unit, the material cylinder is communicated with a first air inlet control unit and a feeding valve, and the first air inlet control unit is suitable for controlling sterile air to be introduced into the material cylinder. The fluid output unit is communicated with a cleaning return pipeline. The fluid conveying source is provided with a supply valve, and the supply valve is connected with the feeding valve through a supply pipeline. The supply pipeline is provided with a highest point, the highest point is higher than the feeding valve, a drainage branch is connected between the position, close to the feeding valve, of the supply pipeline and the cleaning return pipeline, and a material top air ground discharging valve is arranged on the drainage branch. Water in the supply pipeline can be discharged firstly, so that active ingredients in feed liquid can be prevented from being damaged by sterile hot water, meanwhile, dropping pollution and feed liquid waste caused by dilution of the feed liquid can be avoided, and further, the influence of dropping on fluid conveying target performance and product quality can be avoided.

Description

technical field [0001] The invention relates to the technical field of food production, in particular to a fluid delivery system and a control method thereof. Background technique [0002] The production, filling and storage of yogurt and other dairy products require strict production conditions due to their special process. The important preparation before the liquid filling is to sterilize the pipeline, pump body and filling machine that the liquid will flow through. The usual disinfection method is to use sterile water above 90°C to flow through the entire filling system for disinfection. Therefore, before the filling machine feeds, the pipeline is filled with 90°C sterile water. Under this condition, the pipeline material is directly topped with water. The heat of the pipeline and hot water will make the state of the material thinner, and the filling head will drip when filling. The material will cause pollution, and the increase of the material-water mixture will caus...
