High Speed Horizontal 2 Phase Separation Centrifuge Protein / Soybean Separation

High Speed Horizontal PLC Control Protein Soy Production 2 Phase Searation Centrifuge

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 centrifuges are used in the production line. [ZK Separation] high-speed centrifuge (separation factor ≥ 3500G) in the production process plays an irreplaceable important role.

II. Technical characteristics of high-efficiency protein centrifuge

★ High rigidity screw rotor

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 of operation. [ZK Separation] 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 Separation] centrifuge 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 Separation] centrifuge 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.

• Sanitation plan (CIP system)

The centrifuge control system is arranged with a fully automatic cleaning procedure. The multi-step mode of high-speed cleaning→low-speed cleaning (multi-stage)→high-speed multi-level cleaning ensures that it is thoroughly washed per mechanical cleaning. To avoid human factors, a 360° high-pressure cleaning nozzle is used for the hood, the inner cavity of the base, and the outer surface of the drum.

Note: If the liquid phase is discharged by the built-in centrifugal pump with pressure, the overall dimensions differ from the technical table, please contact ZK Separation.

IV. Soybean product high-speed centrifuge parameter table

★ In the industry of soybean products, high-efficiency fully-enclosed high-speed centrifuges are gradually bringing technological innovation in the soybean production line and replacing conventional filter-type equipment. Soybean hulls (similar to medium density) are hard to be removed by common centrifuges. To this end, [ZK Separation] has developed a floating object trap to solve the problem and make the separated soybean milk meet the process production requirements.

Note: The throughput is related to material characteristics;

Control method:

① direct control using an inverter (double-motor double-frequency conversion mode);

② PLO+ touch screen control (intelligent control mode);

Material: AISI321, AISI316, AISI316L SAF2205, etc.

Safety protection: devices for measuring vibration and temperature, emergency stop button, and measures to prevent faulty operation such as hood not being covered.
