Juice clarification and pre concentration

Concentrate and extract tea juice and flower juice (such as rose, chrysanthemum, honeysuckle, etc.)

II Application of dairy products

In the dairy industry, whey protein is concentrated from whey protein and separated from whey cheese, combined with ultrafiltration concentration and NF extraction technology. The company uses imported dairy professional membrane elements, which are applied to different separation and concentration requirements as follows:

Whey protein concentration and separation (WPC/WPI):Using a polymer roll filter membrane, VT, MT&ST ultrafiltration membranes provide the optimal equilibrium flux for protein extraction when collecting whey protein, thereby ensuring the optimal lifespan of the membrane.

High pH and high temperature:Imported ultrafiltration and microfiltration membranes have a "PHT" structure that is resistant to high pH and high temperature. PHT membranes do not require chlorine disinfection, which can extend the service life of membranes and equipment. At the same time, PHT membranes can also withstand high temperatures.

Milk protein concentration and separation:Imported MK membrane elements have been used for milk concentration since 1999, using PES 30KD ultrafiltration membranes and companies that concentrate and separate milk protein from milk. Today, MK membrane elements are widely used due to their excellent performance characteristics.

Separation of whey and casein:The use of imported FR, V0.1 ultrafiltration and microfiltration membranes provides the most economically feasible method for separating casein and whey proteins.

Removal of fat and microorganisms:Standardization is an important process in milk production, and the current method is to use centrifugal separation technology to remove most of the fat in milk. Imported ultrafiltration membranes, such as FR, V0.1, and V0.2 membranes, can be used to remove fat and microorganisms in the manufacture of high-quality WPC and WPIS. Compared with traditional ceramic membranes, this ultrafiltration system has lower operating pressure, lower manufacturing costs, and simpler operation.

Lactose concentration:Xingda Company is honored to announce that our new NFX nanofiltration membrane will be used for lactose concentration. The NFX membrane can prevent 99% of MgSO4 from passing through, while traditional NF membranes can only prevent 98% of MgSO4 from passing through. At equal or greater flow rates, NFX membranes greatly block the passage of lactose, thereby achieving the goal of concentrating lactose.

Clarification of brine water:In the production process of solidified cheese, brine is used to solidify the cheese, and the brine needs to be treated, but it is expensive. Ultrafiltration can clarify the brine, making it reusable. Imported BN membranes can clarify the brine, provide ion balance, and allow the cheese to solidify at the optimal rate.

III Juice clarification and pre concentration

The traditional juice processing techniques include berry selection, cleaning, crushing, pressing, enzymatic hydrolysis, filtration (including coarse filtration and fine processing), and concentration. Although diatomaceous earth and centrifuge filtration in the process can ensure the clarity of the filtrate, the warranty period of the product is not long due to the difficulty in filtering out bacterial microorganisms. In addition, the product yield is low and the operating cost is high. Filter aids and clarifying agents need to be added during the processing, making the process complex and consuming large amounts of raw materials.

Guangzhou Kaimo uses organic tube membranes for juice clarification, which can remove bacteria, pectin, and crude protein that cause juice spoilage. The resulting juice has excellent quality, retaining aromatic components and nutrients. Tube membranes have gradually shown their superiority in juice filtration. The process flowchart and characteristics are as follows:

1. Use polyvinylidene fluoride (PVDF) material tubular membrane, which has the characteristics of high anti pollution, high membrane flux, stable effluent and long service life;

2. During operation, the automatic flushing function is timed and stopped to ensure that the membrane stack will not be clogged;

3. Reasonable process design and short process, bidirectional feeding system, fully utilizing membrane tube filtration performance, greatly reducing production cycle;

4. Stable filtration quality, achieving sterile filtration, good product quality, excellent color, aroma, and taste;

5. Membrane filtration has no temperature rise, phase change, added chemicals, or pollution, effectively retaining nutrients and aromatic components, and the product is green and environmentally friendly;

6. The concentration extraction process has low energy consumption, low operating costs, simple operation, stable operation, and easy maintenance;

7. High degree of automation, integrated data processing, online monitoring and remote operation of configuration, reducing labor intensity;

4 Tea and flowers(Roses, chrysanthemums, honeysuckle, etc)Concentration and extraction

In modern life, tea, food and plant essence, plant essential oil, etc. can be rapidly dissolved. The traditional deep processing technology can be generally divided into mechanical processing, physical processing, chemical and biochemical processing, and comprehensive technology processing. The clarification effect of the product produced by the process is poor, and the taste and quality of the product are not ideal and poor.

The concentration and extraction deep processing technology developed by Guangzhou Kaimo Integrated Membrane Separation Technology applies microfiltration, ultrafiltration, nanofiltration, and reverse osmosis technologies to the deep processing of tea and flowers, overcoming the shortcomings of traditional processes. It can extract various functional components from tea and flowers, produce concentrated and high-purity innovative products, reduce production costs, and improve product quality. The process flow diagram and characteristics are as follows:

1. The multi-stage membrane with different pore sizes has high filtration accuracy, good product stability, and clear and transparent concentrated solution, eliminating turbidity precipitation and "turbidity after cooling" phenomenon;

2. During operation, timed and automatic shutdown flushing is performed. The front-end ceramic membrane has strong anti pollution ability, and the back-end membrane process is resistant to acid and alkali cleaning, ensuring that the membrane system is not contaminated or blocked;

3. Reasonable process design and short process, bidirectional feeding system, fully utilizing membrane tube filtration performance, greatly reducing production cycle;

4. Stable filtration quality, achieving sterile filtration, high fold concentration of tea juice and flower juice, good product quality, excellent color, aroma, and taste;

5. Membrane filtration has no temperature rise, phase change, added chemicals, or pollution, effectively retaining nutrients and aromatic components, and the product is green and environmentally friendly;

6. The concentration extraction process has low energy consumption, low operating costs, simple operation, stable operation, and easy maintenance;

7. High degree of automation, integrated data processing, online monitoring and remote operation of configuration, reducing labor intensity;
