Introduction

Molecular distillation equipment is a complete molecular distillation equipment,including: molecular evaporator,degassing system,feeding system,heating system,cooling vacuum system and control system.

Characteristics

1.The ordinary distillation is separated at the boiling temperature,and the molecular distillation can be carried out at any temperature.As long as there is a temperature difference between the hot and cold sides,the separation can be achieved.

2.Ordinary distillation is a reversible process of evaporation and condensation.A phase equilibrium state can be formed between the liquid phase and the gas phase.In the molecular distillation process,molecules escaping from the evaporation surface directly fly to the condensation surface without colliding with other molecules in the middle.In theory,there is no possibility of returning to the evaporation surface,so the molecular distillation process is irreversible.

3.The ordinary distillation has bubbling and boiling phenomenon; the molecular distillation process is free evaporation on the surface of the liquid layer without bubbling.

4.The separation factor indicating the ordinary distillation separation ability is related to the vapor pressure ratio of the component,and the separation factor indicating the molecular distillation separation ability is related to the vapor pressure and molecular weight ratio of the component,and can be obtained from the relative evaporation speed.

Advantage

1.The distillation temperature is low,and the molecular distillation is operated at a temperature far below the boiling point.As long as there is a temperature difference,the separation purpose can be achieved,which is the essential difference between molecular distillation and conventional distillation.

2.The distillation vacuum is high,and the inside of the molecular distillation apparatus can obtain a high degree of vacuum.Usually,molecular distillation is operated at a very low pressure,so that the material is not easily oxidized and damaged.

3.The distillate film is thin and the heat transfer efficiency is high.

4.The heating time of the material is short,the distance between the heated liquid surface and the condensing surface is smaller than the average free path of the light molecules,so the light molecules escaping from the liquid surface reach the condensation surface almost without collision.Therefore,the distillation material has a short heating time,and the residence time at the distillation temperature is generally between several seconds and several tens of seconds,which reduces the chance of thermal decomposition of the material.

5.The degree of separation is higher,and molecular distillation can separate substances that are not easily separated.

6.There is no boiling bubbling phenomenon.Molecular distillation is the free evaporation on the surface of the liquid layer.Under low pressure,there is no dissolved air in the liquid.Therefore,the whole liquid cannot be boiled during the distillation process without bubbling.

7.Non-toxic,harmless,non-polluting,no residue,can get pure and safe products,and the operation process is simple and the equipment is few.Molecular distillation technology can separate substances that are difficult to separate by conventional distillation.

8.The molecular distillation equipment is expensive.The molecular distillation unit must ensure the high vacuum of the system pressure.The material sealing requirements are high,and the distance between the evaporation surface and the condensation surface should be moderate.The equipment processing is difficult and the cost is high.

9.The product consumes less energy,and the total heat loss due to molecular distillation is small.Due to the unique structure of the molecular distillation unit,the internal pressure is extremely low,and the internal resistance is much smaller than conventional distillation,which can greatly save energy.

In the future, our company will still adhere to the quality policy of 'Quality First, Customer First, Work Together, Pursue Excellence', and strive to be the industry leader with excellent Laboratory Falling Thin Film Evaporation Apparatus for Ethanol Removal.
