Crystallization Reactor

Crystallization reactor Introduction

Crystallization reactor is a crystallization equipment that requires rapid cooling of frozen water or refrigerant water in the interlayer after the material mixing reaction. The requirements for the stirring form, rotation speed, heating and cooling of the equipment are different, and the design, material selection, structure and explosion-proof and non-explosion-proof requirements of the reducer are also different. Therefore, the crystallization kettle can be divided into normal pressure and pressure vessels. The user who needs it should provide the fundamental use.

Crystallization reactor working principles

The crystallization reactor is a crystallization equipment that requires a sharp cooling of chilled water or refrigerant water in the interlayer after the mixing reaction of materials. The key links are the size of the interlayer area, the structural form of the agitator and the form of the material outlet, the high-precision polishing inside the tank, and the cleaning inside the tank. There is no dead angle requirement to meet the process conditions of use.

Structure and performance of Crystallization reactor

●The inside and outside of the crystallization kettle tube is polished, and the heating layer is divided into spiral belt and jacket type. Heating energy is divided into steam and electric heating to choose from.

●The insulation board is made of 304 material and filled with polyurethane foaming agent.

●Equipped with sight glass, stirring device, feeding port, tank washer, respirator, liquid medicine inlet, injection water inlet, return port, steam inlet, condensate outlet, cooling water inlet, outlet, material outlet, Sewage outlet, sampling port, temperature measuring port, liquid level device.

Crystallization reactor advantages

(1) Made of imported 316L stainless steel, the inner wall is polished with electrolytic mirror, and the outer wall is made of 304 all-welded structure for heat preservation and electrolytic matt treatment.

(2) Install a 0.2 μm hydrophobic vent filter on the kettle body.

(3) It can withstand high temperature sterilization at 121°C and is equipped with a sanitary pressure gauge.

(4) The external connection port of the tank body adopts a sanitary chuck.

(5) Equipped with temperature monitoring device, 2 sight glasses, cleaning ball and nitrogen inlet.

(6) The seal of the shaft adopts a special sanitary mechanical seal to ensure that the material is not polluted.

Crystallization reactor application

This product is used for hydrolysis, neutralization crystallization, distillation, evaporation, storage and other production links in the pharmaceutical, chemical, food, light industry and other industries.

Crystallization reactor purpose - Extract oil

Dissolve oil

Dissolve the clarified oil in pentane, making sure the vent/condenser of the jacketed vessel is connected to a suitable blower motor or fume hood to vent pentane vapors. The boiling point of pentane is 36 °C. Pentane releases many vapors even at lower temperatures. , make sure the vessel condenser cools down to -20 °C. Add pentane and oil in a 1:2 ratio in a jacketed vessel. Turn on agitation and turn on the heating bath and set to 45 °C. Wait until the solution reaches 45°C and all the oil is dissolved.

Precipitation

Set the bath to 5°C. Slow down mixing speed. crystals will form spontaneously or "flush" out of the pentane solution. Continue to reduce the temperature to at least -10 degrees Celsius. The temperatures you use and how they change over time can change the growth of the crystals.

Collect crystals

Once precipitation has stopped, rinse or physically remove crystals from the reactor. Rinse the crystals with ice-cold pentane to flush impurities from the crystal surfaces. More rinses with pentane can improve poor color, but reduce overall yield. Keeping the and material cool during this step will help improve yields.
