Product introduction:

5KV intelligent dual-display megohmmeter has high test voltage and strong output. The measured object often has power frequency leakage or high-voltage interference on the sensor. Therefore, for personal safety, the instrument must first be connected to a safe grounding wire! !

After the instrument is turned on at high voltage, please do not use the manual discharge method to check the instrument. After the test is completed, you should wait for the instrument to automatically discharge so that the voltmeter on the LCD screen will return to zero before carrying out the routine manual safety needs of manual discharge! Because the short-circuit discharge of a strong electrical pulse wave damage the measured object's insulation life, if the pulse breaks into the meter, it will also damage the integrated circuit within the instrument! !

5KV intelligent dual-display megohmmeter is designed and developed by our company to solve the electrical insulation resistance characteristics of large-scale high-voltage transformers, electrical appliances, long-distance power cables or buried cables under the strong interference of high-voltage substations and power plants. It can also be used for electrical insulation resistance measurement in a wide range of fields.

In the edible oil pressing plant, before the extrusion of oil from oil containing materials, an oil pretreatment process is typically undertaken to improve the efficiency of production and to ultimately save on costs. The entire oil milling process generally includes: cleaning, sieving, hulling, separation, cracking, particle making, frying, softening, flaking, drying, and expelling oil materials. The process: cleaner --> sheller --> huller --> crusher / flaker --> steam cooker --> softening --> extruder --> dryer.

Oil Pressing Plant Pretreatment

In the oil pressing plant/edible oil pressing plant, the pretreatment process typically involves working procedures for removing impurities from the oil material. Such impurities include the following items:
  • Organic impurities, such as stems and leaves, cords and chemical fibers.
  • Inorganic impurities such as soil and metal.

Advantages of Our Oil Pretreatment Technology

  • Heated shelling features means to reduce energy consumption.
  • Double dehulling process which raises the shelling ratio to up to 85% with oil residue in hulls reduced to below 1.5%.
  • Large-volume silos to facilitate adjustments to production capacity.
  • Can produce oil cake as different grades and various protein levels which are adjustable to meet special requirements. Soybean cake can also be milled.
  • With years of research experience on screw Oil Press machine ,we can reach residual oil and low energy consumption. 
  • Complete pre-treatment system can be controlled automatically.

The Goal of Oil Pretreatment

  • Improve the quality of the oil and the cake.
  • Increase rate of productivity; reduce residual oil.
  • Increase treatment capabilities of the equipment.
  • Lessens wear and lengthens the life of the equipment.
  • Ensures safety.
  • Expansion improves the rate of productivity and the quality of the oil cake.

Oil Pretreatment Process

  • Warm hulling process reduces energy consumption.
  • Double cracking and hulling process improves the hulling ratio and reduce oil residue in the hull.
  • High volume hull bin makes production flexible.
  • Makes it possible to produce meals of various protein content (includes meal milling).
  • Adopts the complete explosion puffing process.
  • Automated controls.
