Description
Technical field
The present invention relates to a kind of esterification device field, particularly relate to a kind of reactor for continuous seepage ethyl butyrate.
Background technology
Ethyl butyrate is mainly used in spices, essence extraction and makes solvent.Ethyl butyrate also can be used in flavor formulation, as banana, pineapple etc., and adjustable multiple Fruity type essence and other flavor essence.Traditional preparation method carries out esterification primarily of n-butyric acie and ethanol and obtains.But at present industrial mostly adopt have charging aperture, under have the batch (-type) reaction kettle of the esterification of discharging opening, its production efficiency is lower, can not realize continuous and automatic large-scale production.Material can not fully mix by the stirred tank for routine, and temperature is not easily controlled, thus makes the quality of product low.
Summary of the invention
In order to overcome the shortcoming that the production efficiency existed in above-mentioned technical problem is low, mixing of materials is uneven and product quality is low, the invention provides a kind of reactor for continuous seepage ethyl butyrate.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of reactor for continuous seepage ethyl butyrate, comprise the skirt of kettle and support kettle, the top and bottom of kettle are respectively arranged with material outlet and material inlet, material inlet is provided with feed pipe, feed pipe is also provided with shower nozzle, reactor outside is also provided with feed proportioning tank and measuring pump, described feed proportioning tank is provided with head tank charging aperture, agitating device is provided with in feed proportioning tank, described metering delivery side of pump is communicated with the charging aperture of reactor, also be provided with at least two-layer mixed reactor in reactor, and be connected with temperature controller in still.
Further, described reaction kettle body upper end is provided with capping.
Further, the agitating device in described feed proportioning tank has a blade and a reinforcement.
Further, described temperature controller comprises temperature detecting unit, temperature display unit and temperature control unit, and control unit is connected with detecting unit by circuit with display unit.
Further, described mixed reactor is six layers.
First a kind of reactor for continuous seepage ethyl butyrate provided by the present invention is fully uniformly mixed by the agitating device in feed proportioning tank, by measuring pump, the butyric acid in head tank, ethanol and catalyst mix raw material are accurately delivered in reactor continuously again, by six layers of mixed reactor, ensure that three kinds of materials fully contact and successive reaction, ensure that the flowing of material in reaction tower, thus improve production efficiency and product quality, also ensure that the mixture homogeneity of material.
