Bone soup/bone extract contains abundant protein components (after enzymatic hydrolysis, they become bone peptides). After filtration and concentration, it can be used as a food additive and has been widely applied in the food and health supplement industries. Generally, raw materials such as pig bones, cow bones, sheep bones, chicken bones, and fish bones are crushed and then boiled. After boiling, the bone soup undergoes preliminary sedimentation/centrifugation to obtain a milky white bone soup liquid (obtained after enzymatic hydrolysis as the bone peptide liquid). The traditional bone soup liquid requires multiple levels of centrifuges for oil and impurity removal, and the resulting filtrate is a turbid liquid, not clear enough. The centrifugal process is energy-intensive, labor-intensive, and difficult to achieve automation. 

Wuhan Bona specializes in the development of membrane separation and concentration technology and the production of membrane equipment. They have developed an integrated process of membrane filtration and membrane concentration to replace the traditional process. Firstly, they use membrane filtration technology to pre-treat the raw bone soup liquid, removing colloids, oils, bone debris and other impurities, while retaining most of the effective components such as proteins in the bone soup. Then, the filtrate is sent to the membrane concentration equipment for concentration. The bone soup can be concentrated by up to 10 times or more, with protein content reaching over 40%. Our company optimizes the membrane core selection of the membrane concentration equipment to increase the concentration speed by 1 times and realizes the automated process of bone soup filtration and concentration, effectively reducing the concentration energy consumption and cost. 

Process Characteristics: 

Membrane filtration pretreatment can withstand high temperatures. The bone broth does not need to be cooled down, thereby reducing energy loss. 

2. The filtrate obtained after pre-treatment is clear and transparent, with high quality and excellent pre-treatment effect. 

3. The membrane concentration process can withstand high temperatures and can reduce energy loss. 

4. The membrane concentration process uses imported membrane elements, which have stable quality, high concentration efficiency, high concentration ratio, and excellent product quality. 

5. Optimization of membrane concentration process involves selecting the appropriate membrane core, resulting in high production efficiency. 

6. The entire process does not involve any phase change, effectively preserving nutrients and active ingredients. 

7. The entire process does not require the addition of any chemicals and is pollution-free. It is a green and environmentally friendly technology. 

8. Optimize the system design, with reduced total energy consumption, lower operating costs, simple operation, smooth running, and convenient maintenance; 

9. The system is fully automated, capable of performing integrated data processing and real-time monitoring, thereby reducing labor intensity.
