Fresh milk ceramic membrane microfiltration treatment system

Abstract

The invention provides a fresh milk ceramic membrane microfiltration treatment system. The fresh milk ceramic membrane microfiltration treatment system comprises: a balance tank for storing milk; a power module for conveying milk in the system; a ceramic membrane module for carrying out ceramic membrane microfiltration on milk by utilizing a ceramic membrane; a transmembrane pressure difference control module for controlling the concentration side pressure and the permeation side pressure of the ceramic membrane; and a temperature control module for regulating the temperature in the fresh milkceramic membrane microfiltration treatment system.

Description

technical field [0001] The invention relates to the field of dairy production, in particular to a fresh milk ceramic membrane microfiltration treatment system. Background technique [0002] The current practical microfiltration ceramic membrane process for milk treatment is mainly as follows: After the milk is simply separated, it is heated to 50-55°C and then directly enters the microfiltration ceramic membrane module, and the bacteria in the milk is removed through the separation of the microfiltration ceramic membrane. Body, body cells and other large particles. In the control of the microfiltration module, the module uses the concentration side pressure sensor, the inlet temperature sensor, the inlet and outlet electromagnetic flowmeter, and the circulation pump frequency converter to regulate and control. [0003] This method has the advantages of real-time monitoring of pressure, temperature and flow, which can ensure the processing capacity of the system and the safe...

AI Technical Summary

Problems solved by technology

[0005] 2) The surface of the ceramic microfiltration membrane is easy to form a secondary pollution film layer, which affects the processing capacity of the overall microfiltration system;

[0006] 3) As the treatment capacity decreases, the pressure is forced to increase continuously, so that some pollutants enter the membrane structure due to the pressure, resulting in more serious pollution;

[0007] 4) The system processing capacity will decline seriously as the running time prolongs;

[0008] 5) Frequent CIP (Clean In Place) cleaning, resulting in a large amount of cleaning wastewater;

[0009] 6) The service life of the system is only about 1-2 years
