Product Description
+++ vitamins Vitamins are called "ten thousand years" products. They are a kind of organic substances that are necessary to maintain animal life. They are also important active substances to maintain the body's health.Vitamin C production has two fermentation processes: Reichstein method and two-step fermentation. Impurities in fermentation broth are removed by the use of heat precipitation method for the above two traditional vitamin C extraction process .After the fermentation broth was allowed to settle, it was separated by a cation exchange resin. However, the fermentation broth is passed directly through the ion exchange resin, which can cause serious contamination of the resin surface and reduce the exchange capacity.Modern extraction process generally applies ultrafiltration membrane gulonic acid fermentation broth production, because the broth protein molecular weight range is generally 1-10kDa, so to choose a certain molecular weight cut-off can remove most of the protein and some macromolecular impurities in place of the traditional heating method to remove protein.Compared with the traditional process, Gulonic acid fermentation broth has obvious advantages: simple process, fully automatic operation and good stability; the yield is improved, generally reach more than 99% during membrane filtration for removing impurities . At present, integrated membrane technology including ceramic membrane ,ultrafiltration &nanofiltration membrane are applied to vitamin C production enterprises because membrane process has more important feature is the separation of relatively high accuracy, which can be verified from the fermentation broth protein removal rate.Vitamins: Vitamin C, vitamin B2, vitamin B12 and so onDepending on the requirements of each particular application, atech innovations offers a wide range of different membrane designs. The standard range includes single-channel and multi-channel membranes with various channel diameters suitable for ultrafiltration (starting at 5 kD) and microfiltration (up to 1.2 µm).
Product DescriptionJIUWU Ceramic membrane element is made from alumina and zirconia which is an asymmetric membrane structure with multi-channel tubular shape. The pore is on the channel. Driven by operation pressure, the liquid is running in the membrane. The part less than pore size is permeation, the part lager than pore size is concentrated liquid, so as to achieve the separation, concentration and purification purposes.
Ceramic Membrane System
Skid-mounted device (Ceramic Membrane Filtration System) effectively allocates and stores machine for process and modular systems in the field of solid-liquid separation. A CMF skid-mounted device is designed by order and fully optimized as process flow, which includes CMF unit, power part, control part and supporting pipelines, valves and instruments. The device can be designed as a containerized device.
Ceramic Membrane ModuleHousing is designed with standard connectors (flange, clamp, whorl coping) to attach with incoming and outgoing piping. This includes a manifold, which directs incoming flow to all ceramic membrane elements in the housing. The housings are produced from different types of stainless steel, coated steel or plastic, titanium, as required by the application. The sealing material holds elements in the weakest place in housings. A wide array of materials (EPDM, Fluoro rubber, silicon) is available by customer's needs.
Ceramic Membrane Element
As a core technology, JIUWU has become the largest ceramic membrane element producer and a world leader in cross-flow filtration. JIUWU ceramic membrane element is tubular composite membranes on an open porous carrier tube made of high purity α-alumina oxide (AL2O3) and titanium oxide (TiO2). The ceramic membrane element is optimized for maximum water permeability and high mechanical stability.

FAQWhat Are The Advantages Of Ceramic Membrane?Compared with such traditional filter like polymer membrane, ceramic membrane has many unique advantages:High separate accuracy, limpid and transparent filtrate with little content of impurity;
• Pure aluminium oxide brings membrane excellent performance on resistance to acid and alkali and makes the membrane longer working life;
• No additive needed, the dense bacterial residue can be recycled as feed, so it's an environmental friendly technology;
• Operate under normal temperature and duration, which ensure product activity. More of the original flavour and aroma of the fruit is retained;
• Higher yield rate of high quality products;
• The membrane pore size keeps asymmetric distribution and low slow decay, and maintain high flux filtration;
• Greatly reduce the discharge of waste;
• Membrane runs with high strength and excellent wear resistance
• Controlled by PLC automatically
• Less grounding necessary for installation &small footprint
How Does Ceramic Membrane Work?During filtration by means of ceramic membrane made by JIUWU the medium to be filtered flows through the channels of the membrane carrier. All particles whose size exceeds the pore radius of the membrane are retained. The particles /molecules build up in the concentrate. The filtrate permeates through the pores and depending on the procedure is subjected to subsequent process stages. This filtering method is also called "cross-flow filtration" or "dynamic filtration" . Cross-flow management can achieve stable fluxes. Cleaning is performed by means of backward flushing or chemical cleaning.
Does Ceramic Membrane Need To Be Cleaned?Membrane fouling is a major obstacle to wide spread application of the membrane. It is the phenomenon whereby the membrane permeated flux decreases and the transmembrane pressure (TMP) rise with the passage of time due to the membrane fouling. To solve the problem, cleaning step is must be took, or the membrane after using can be exchanged.
What Is The Structure Of Ceramic Membrane?From the perspective of microstructure, the inorganic ceramic membrane has two structures: "symmetric ceramic membrane" and "asymmetric ceramic membrane". Since asymmetric ceramic membrane has better mechanical strength and higher permeation flux, which has dominated industrial application. Industrially applied and widely promoted porous ceramic membrane is mainly composed of three layers: the supporting layer, transition layer, separation(membrane) layer.
