Protein Extraction

Protein is an important substance that constitutes the human body, and it is also the basic substance of human life. Separating valuable proteins from plants is a very important process. Plant protein is extracted from soybeans, peas, and the like via a common acid-salt extraction process. In addition to its nutritional value, plant protein has many important functional properties. In the process of producing protein powder, to increase the output and the extraction rate as much as possible, an increasing number of decanter centrifuges are used in the production line. ZK protein decanter for the protein production process can be used to wash, extract, concentrate, and clarify proteins.

ZK SEPARATION Decanters for Protein Production Process

In producing protein powder, to improve the production efficiency and extraction rate as much as possible, ZK food-grade protein centrifuges are more and more applied to the production process line, playing an increasingly important role in the production process. The ZK protein centrifuge has a high-rigidity rotating rotor to ensure the bearings' service life under high-speed rotation. Simultaneously, it has a foam crushing device and a fully automatic cleaning program, which effectively improves the separation rate and reduces workforce maintenance costs. Fully enclosed high-speed centrifuges with high efficiency are gradually causing technological innovations in soy product production lines and are replacing traditional filter-type equipment.

ZK Protein Isolation Decanter Features and Benefits

  • High Rigidity Screw Rotor

    Decanter centrifuge is a typical double-rotor differential high-speed rotating device. Its separation factor in the protein industry is up to 3500G, which is the feature of a high-speed centrifuge. The rigidity of the rotor and the control of the unbalance amount are important factors for the stability ofoperation. ZK centrifuge is designed in strict accordance with JB/T 8051-2008 centrifuge drum strength calculation specifications. The screw rotor (flexible in high speed state) is put under finite element modal analysis, so that the working speed is far from the first-order and the second-order critical speed to avoid the occurrence of resonance at high speed, ensuring the bearing service life and lowering vibration and noise.

  • Bubble Breaker

    At the acid-sinking section, the high-speed centrifuge will produce a large amount of bubbles in the separation and liquid discharging processes. If the bubble is not broken, it is easy to to take out protein. ZK protein isolation decanter is internally set with a bubble breaker, which plays a good role.

  • Discharge Device for Centripetal Pump With Pressure

    The bubble generated during the draining process of the centrifuge is easy to block the drain pipe, causing the fluctuation in the operating current of the centrifuge. ZK protein isolation decanter is internally provided with a discharge device for centrifugal pump with pressure to avoid the supernatant being ejected at high speed. The device is particularly suitable for the condition that the liquid phase is directly input into the next section or the next working condition of equipment after separation. For example, in the protein separating process, the soybean milk after first and second extraction enters the acid precipitation tank, and if this device is used, the intermediate transition tank, the transfer pump, and related pipes and instruments are needless.

Why Choose ZK Decanter Centrifuge ?

  • ease to use decanter
    Easy Operation

    ZK decanter can run continuously and automatically. The control of the decanter centrifuge is completed through the touch screen of the control panel, and the one-key start and stop of the decanter can be realized through the control panel. The control panel interface is simple and easy to be understood, and operators can easily monitor the working status and understand the operating parameters.

  • durable
    Durable

    All wear-prone areas of ZK centrifuges (separation liquid outlet, solids discharge output, screw conveyor and solids discharge section) are made of abrasion resistant material, and the rotating parts are made of high-strength centrifugally cast stainless steel. For the wear-resistant requirements of special industries, replaceable hard alloy wear-resistant pieces are added to the spiral blades.

  • lubrication
    Lubrication Ways

    In order to meet the actual needs of different customers, ZK decanter centrifuge provide three different lubrication ways (grease pump grease lubrication, lubricating oil circulating lubrication and oil mist lubrication) for customers to choose. All lubrication systems can re-lubricate the rotor bearings during centrifuge operation.

  • security
    Safety and Security

    ZK decanter differential speed automatic control technology can automatically adjust the screw conveyor differential speed, to prevent overload and blockage. At the same time, ZK decanter centrifuge has vibration protection, bearing temperature protection and overload protection system. This can avoid critical operating conditions and prevent damage to centrifuge components and bearings.
