Product Description:        To improve extraction efficiency and shorten the leaching time of active tea components, high-temperature water extraction is generally adopted in tea processing. Under specific conditions of temperature, duration, and agitation, effective components such as tea polysaccharides, tea polyphenols, and trace elements are extracted from the tea leaves. The resulting tea broth often lacks clarity due to the simultaneous extraction of impurities like pectin and fibers, necessitating further clarification and purification. The concentrated tea juice commonly purchased online is a high-concentration product obtained by concentrating the extracted liquid. This article uses our company’s instant tea powder production line in Yunnan Pu’er as a case study to explain the domestic processes of tea extraction, filtration, and concentration, providing useful information for those interested in learning more.      Traditional tea extraction involves coarse filtration using methods like plate and frame or diatomaceous earth after leaching, followed by thin-film evaporation or other vacuum concentration techniques to obtain concentrated tea liquid. However, this results in poor clarity, low purity, and compromised taste due to thermal degradation during thin-film evaporation. Additionally, the energy consumption for concentration is high, typically requiring 0.8–1 ton of steam to evaporate one ton of water, resulting in a dehydration cost between RMB 260–300.      Modern tea extraction lines now incorporate advanced membrane separation technology to enhance quality and reduce energy consumption. For example, one Pu’er tea company’s instant tea powder production process is as follows:Tea extraction → Centrifugation → Ceramic membrane filtration → Nanofiltration membrane concentration → Vacuum concentration → Drying      Given the complex composition of tea liquid and high requirements for product flavor, the combination of ceramic membrane filtration and nanofiltration membrane concentration replaces traditional thin-film evaporation. This approach effectively removes impurities such as colloids, macromolecular proteins, and fibers while preserving the active components of the tea, achieving physical clarification and purification. The filtrate is then processed through a nanofiltration membrane system to increase concentration and yield. This method maintains the original flavor of the tea while significantly reducing energy consumption—typically costing only RMB 8–15 to remove one ton of water via membrane concentration. Treating 20 tons of tea liquid with nanofiltration can yield approximately 2.5 tons of concentrate at 15% concentration. If the desired concentration is not achieved, further vacuum concentration may be applied. The dried powder from the concentrate exhibits excellent dispersibility, high purity, rapid dissolution in water, and superior clarity.     For more information on complete equipment for instant tea powder production lines, please contact Engineer Zhang at Chongqing Jiahe Filtration Technology Co., Ltd. I will provide tailored solutions based on your specific needs. You are also welcome to visit our company to see the actual equipment or conduct on-site sample tests to observe the separation effects. more>

Category: Chemicals/Mixing Equipment/Mixers

Company: Jiangsu Zhuoya Environmental Protection Co., Ltd.

Product Description: The application of mixers in water and wastewater treatment is an important field in fluid mixing. The following diagram illustrates the different applications of mixers in these two processes, involving operations such as rapid mixing, flocculation, chemical preparation and storage, neutralization, homogenization, anaerobic mixing, and sludge blending. I. Rapid Mixing   The function of a rapid mixer is to uniformly blend the added chemicals with the raw water within the retention time. From a mixing perspective, the rapid mixing process is a flow-controlled process. Therefore, selecting medium to high-flow axial-flow impellers is most appropriate.   For a long time, a traditional design method for rapid mixers has been based on the G-value or GT-value. This concept was proposed by T.R. Camp in the forties and fifties, with the G-value correlation expressed as:   The GT-value is the product of the G-value and the average retention time (T). Both the G-value and GT-value only consider the volume of the rapid mixing tank, water treatment capacity, mixer shaft power, and water viscosity, without accounting for the efficiency of the impeller itself.   The G-value originated from inefficient (low-flow) radial-flow impellers. If efficient axial-flow impellers are selected while still using the traditional G-value or GT-value for design, the selected mixer's power and the discharge flow generated by the impeller will far exceed the mixing requirements of the rapid mixing process itself. Therefore, with the advancement of mixing technology, the G-value and GT-value are now only used as reference values for mixer selection and design.   The design method for efficient axial-flow impeller rapid mixers is based on the mixer's discharge flow, using the ratio (N) of the discharge flow generated by the impeller during the average retention time to the effective volume of the rapid mixing tank as the basis for selecting and designing rapid mixers. Due to factors such as chemical dosage, mixing tank geometry, and other influences, this ratio is not fixed but generally requires n>1.5. For the same impeller achieving the same mixing effect (i.e., the same ratio n), the mixing power will decrease as the D/T (where T is the tank diameter or equivalent diameter) value increases. In other words, there is not just one suitable mixer for a mixing process; multiple combinations of mixing power, rotational speed, and impeller diameter are possible. II. Flocculation   In the flocculation process, the role of mixing has two aspects: first, mixing to promote collisions between fine particles, allowing them to gradually grow; second, solid suspension to ensure that the aggregated particles are uniformly suspended in the liquid, preventing sedimentation in the flocculation tank. Additionally, an important constraint in the flocculation mixing process is the shear stress generated by the shear rate, which can break the flocculated particles. This is why the limitation of tip speed is often considered in flocculation mixer design. The FRF series of mixers are specifically designed for the flocculation process, featuring very low speed, high discharge flow, and efficient axial-flow impellers. Therefore, the traditional G-value or GT-value is also only used as a reference.   more>

Category: Chemicals/Chemical Intermediates/Intermediate Compounds

Company: Jiaozuo City Libo Light Alloy Co., Ltd.

Product Description: Pei Yingying  186258 79268Due to the strong electrochemical activity of the zinc plate, after connection, a large number of excess electrons from the zinc plate flow along the wire into the copper and iron plates.In the formula, ------ the number of electrons flowing from the zinc plate into the iron plate.When e1 is sufficiently large, it can offset the electron flow e_corrosion that originally caused the pitting corrosion of the iron plate. At this point, no more electrons flow from the iron plate into the copper plate along the wire. The current direction in the circuit is from the iron and copper plates through the wire into the zinc plate, and then from the zinc plate through seawater back to the iron and copper plates. Therefore, the pointer on the ammeter will point to zero or reverse. This indicates that the corrosion current of the iron has disappeared, the iron plate no longer undergoes pitting corrosion, and is thus protected. Due to the connection of the zinc plate, both the iron and copper plates in the corrosion cell become cathodes and are protected, hence this protection is called cathodic protection.The principle of cathodic protection is explained below using polarization curves. To simplify the explanation, the cathodic and anodic polarization curves are approximated as straight lines.The cathodic polarization curve is the anodic polarization curve, and the two intersect at point S. The corresponding current c is the corrosion current of the system, and the corresponding potential c is the corrosion potential (or mixed potential) of the system.When cathodic protection is applied to the system, meaning a cathodic current is applied to polarize the cathode, the total potential of the system shifts in the negative direction, such as to 1. At this point, the total current on the cathode is 11, equivalent to the segment E1Q. Part of this current is externally applied, equivalent to segment PQ, while another part is still due to anodic corrosion, equivalent to segment E1P. It can be observed that the anodic corrosion current 1 is smaller than the corrosion current c, meaning the anodic corrosion rate is reduced, providing some protection.When the externally applied current continues to increase, the system's potential will further shift in the negative direction. When the potential reaches the equilibrium potential of the anode, the anodic corrosion current becomes zero, achieving complete protection. At this point, the cathodic current lp (equivalent to the segment) is entirely externally applied. This externally applied current is called the minimum protection current, and the corresponding potential is called the minimum protection potential (generally, polarizing the metal from its stable potential by 200–300 mV in the negative direction in seawater can achieve complete protection).(1) Main Parameters of Cathodic Protection: Protection PotentialProtection potential refers to the potential value required to stop metal corrosion during cathodic protection. To completely halt corrosion,the potential of the protected metal must be polarized to the active anode's [open-circuit] potential. For steel structures, thispotential is the equilibrium potential of iron in the given electrolyte solution.The protection potential value has a certain range. For example, the protection potential of iron in seawater ranges between -0.80 to -1.0 V (silver/silver chloride electrode). When the potential is more positive than -0.80 V, iron cannot be fully protected, so this value is alsoreferred to as the minimum protection potential.The protection potential value is often used as a criterion to determine whether cathodic protection is complete. By measuring the potential values at various parts of the protected structure,the protection status can be understood. Therefore, the protection potential value is an important indicator for designing and monitoring cathodic protection.Pei Yingying 186258 79268 more>

Company: Jiaozuo City Libo Light Alloy Co., Ltd.

Product Description: Pei Yingying  1862587  9268II. Cathodic Protection Sacrificial Anode Anti-Corrosion MeasuresThe main reason for the corrosion of ballast tanks is the electrochemical reaction occurring on the submerged steel plate sections. Seawater is a strong electrolyte, and since the ship's steel is not a pure ideal metal but an alloy composed of iron, carbon, and other metallic elements, numerous micro-cell pairs form on the steel surface due to variations in electrode potential at different locations. The micro-anode areas suffer corrosion, while the micro-cathode areas remain unaffected. According to electrochemical corrosion theory, the corrosion of the ship's steel plates in seawater is caused by the action of these micro-cells.III. The arrangement of sacrificial anodes should follow the following principles:(1) The sacrificial anodes required for the ship's outer plates should be uniformly and symmetrically arranged along the bilge keel and the flow lines before and after the bilge keel to reduce additional resistance of the hull;(2) The sacrificial anodes required for the propeller and rudder should be uniformly arranged on the stern shell plate and the rudder. Sacrificial anodes should not be placed on the shell plate within 300 m of the propeller blade tip or in the anode-free zone of single-screw ships;(3) The sacrificial anodes required for the sea chest and sonar transducer well should be arranged inside the chest and well.IV. Installation of Sacrificial AnodesSacrificial anodes can be installed by welding or bolting. Generally, the welding method is simple, provides high installation strength, and has low contact resistance, while bolting allows for easier replacement without damaging the coating on the surrounding area or the reverse side of the steel plate.The following points should be noted during the installation of sacrificial anodes:(1) Before installation, the back of the anode should be coated with an insulating paint. The hull surface at the installation site should also be coated with insulating paint or padded with other insulating materials to prevent detachment due to corrosion on the back of the anode and to ensure the back remains inactive. The usable area of the anode should match the design value;(2) The anode surface must not be painted or contaminated and should be protected before painting and launching;(3) During installation, the anode should be welded to the designated position, with the back tightly pressed against the hull surface. The welding points of the iron feet should be repainted.Pei Yingying   186258   79268 more>

During the cathodic protection process, the anode consumes uniformly, resulting in a longer service life. In practical applications, the measured working potential ranges between -1.8V to -1.85V, providing more effective protection for target structures. In soils with resistivity above 8000 ohm·m, high-potential magnesium anodes are recommended. Application Scope: In sacrificial anode cathodic protection systems, magnesium anodes can be used in soil or freshwater environments with resistivity ranging from 20 ohm·m to 100 ohm·m. In nature, most metals exist in compound forms. Through refining, energy is imparted to transform them from ionic states to atomic states. However, reverting to their natural state is an inherent characteristic of metals. The process where metals react with surrounding electrolytes and transition from atoms to ions is called corrosion. The fundamental principle of cathodic protection is to supply a large number of electrons to the metal, keeping the protected metal in an electron-rich state, ensuring uniform negative potential across all points, and making it difficult for metal atoms to lose electrons and dissolve into ions. This can be achieved through two methods: sacrificial anode cathodic protection and impressed current cathodic protection. Therefore, to prevent corrosion in water pipelines, sacrificial anodes are used, and magnesium anodes serve this purpose effectively. It is known that magnesium anodes in water pipelines prevent corrosion. Complete Sets of Magnesium Alloy Sacrificial Anodes | Specialized for PipelinesJiaozuo Libo Anti-Corrosion Materials: Magnesium alloy sacrificial anodes, aluminum alloy sacrificial anodes, zinc alloy sacrificial anodes, reference electrodes, test stations, backfill materials, impressed current cathodic protection, high-silicon cast iron anodes, deep well anodes, potentiostats, thermite welders, insulating supports, insulating joints, and more.The primary function of magnesium anodes is corrosion prevention, extending the service life of gas pipelines. Magnesium anodes come in four common specifications, typically equipped with a 3-meter, 10-square-millimeter cable, though cable length can be customized based on customer requirements. Based on customer procurement experience, the 14kg and 22kg magnesium anodes are frequently used due to their higher weight and longer protection lifespan. Before leaving the factory, magnesium anodes can be assembled into complete sets, including one magnesium anode, backfill material, and a cotton bag, packaged together. With cables pre-attached, on-site installation only requires welding the cable to the pipeline and applying anti-corrosion treatment. This simplifies installation, improves construction efficiency, and makes it easier for on-site teams to weld the magnesium anodes. Complete Sets of Magnesium Alloy Sacrificial Anodes | Specialized for PipelinesMagnesium anodes can not only be installed for corrosion protection in gas pipelines but also for protecting buried storage tanks, whether for oil or water storage. Installation on storage tanks is similar to pipelines: weld the cable and apply anti-corrosion treatment. This anti-corrosion step is critical—though simple, it must be done carefully to prevent water seepage and air exposure. After installation, the magnesium anode should be saturated with water to ensure it is thoroughly soaked, creating a better working environment underground. This ensures accurate potential and more effective protection. Once installed, the system can be used with confidence. more>

This involves combining solar cell modules with building materials to create building components that serve as the building's exterior surface materials. Alternatively, specialized modules can be directly used as roofing or curtain wall materials to cover the building surface, making the photovoltaic modules an integral part of the building. Moreover, considering the application of photovoltaic power generation during the architectural design phase allows for the integration of architectural design and photovoltaic system design, achieving the best combination of architecture and photovoltaics: maintaining the building's aesthetics while maximizing the power generation efficiency of the solar system.        Mangzhong Construction always adheres to the philosophy of "Creating Brilliance Through Quality" and maintains an attitude of "Serving with Heart, Emotion, and Intelligence." With strong technical R&D capabilities in solar power generation systems, engineering design expertise, and extensive project experience, the company strives to repay the trust placed in it by its customers.Company Name: Jiangsu Mangzhong Construction Co., Ltd.Business Scope: EPC for Photovoltaic Power Stations and Investment in Photovoltaic Solar Power StationsCompany Landline: 025-5888 3737Mobile Number: 159 5163 4545Company Website: http://www.mangz.cn more>

Product Description:       The capacity of a fully premixed low-nitrogen steam generator, which is the evaporation rate of the boiler, refers to the amount of steam produced per hour by the steam boiler, measured in t/h (or g/s). In large steam boilers, capacity is further divided into rated evaporation capacity and maximum continuous evaporation capacity.      The rated evaporation capacity of a fully premixed low-nitrogen steam generator refers to the specified evaporation capacity under rated steam parameters, rated feedwater temperature, and using design fuel, while ensuring thermal efficiency. The maximum continuous evaporation capacity of a steam boiler refers to the maximum evaporation capacity achievable during long-term operation under rated steam parameters, rated feedwater temperature, and using design fuel.      The rated steam parameters for the rated evaporation capacity of a fully premixed low-nitrogen steam generator include rated steam pressure and rated steam temperature. Rated steam pressure refers to the outlet steam pressure that must be guaranteed during long-term operation of the steam boiler under specified feedwater pressure and within the specified load range, measured in MPa.      Rated steam temperature refers to the outlet steam temperature that must be ensured during long-term continuous operation of the steam boiler within the specified load range, under rated steam pressure and rated feedwater temperature, measured in degrees Celsius. In modern power plant boilers equipped with reheaters, the steam parameters of the steam boiler include not only the rated superheated steam parameters but also the rated reheat steam parameters. more>
