Description
Technical field
The present invention relates to natural pigment and extract processing technique field, the high vacuum continuous liquid-discharging device used in especially a kind of course of processing.
Background technology
The natural pigment extract is in order to reduce its damage in leaching process, so the requirement to temperature, vacuum tightness and degree of oxidation is very high in leaching process.Natural pigment extract Lutein medicinal extract poor fluidity, under high vacuum condition, used the high vacuum auto liquor drainage tank, and during the work of high vacuum auto liquor drainage tank, when liquid level reach a certain height, vacuum-pumping valve is closed, and system stops feed liquor.Liquid pump under vacuum state is not easy to be drawn out of, and needs the air valve door to open, and after broken sky, with liquid absorbing pump, pot liquid is beaten away.When liquid level is reduced to certain altitude, the air valve door is closed, and vacuum break valve is connected with system, after broken sky, all will again vacuumize at every turn; Discharge opeing after broken empty, flow is low, poor continuity, efficiency is low, and lutein extract solidifies and is not easy to discharge when in container for storing liquid, temperature is too low.Broken sky causes the instantaneous reduction of vacuum tightness, frequently vacuumizes, broken sky causes the vacuum pump load larger, and the operation of equipment is caused to bad impact.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of high vacuum continuous liquid-discharging device, do not need brokenly sky to get final product drawing liquid, the vacuum pump load is less.
In order to realize the foregoing invention purpose, the invention provides following technical scheme: a kind of high vacuum continuous liquid-discharging device, comprise short-path evaporator, the first container for storing liquid, the second container for storing liquid, vacuum apparatus and interchanger, the concentrated solution outlet of described short-path evaporator is communicated with described the first container for storing liquid through described interchanger, described the first container for storing liquid is communicated with described the second container for storing liquid, and described the second container for storing liquid all is communicated with described vacuum apparatus with described short-path evaporator; On described the first container for storing liquid arrangement height, lower than described the second container for storing liquid, described the second container for storing liquid bottom is provided with Send out pump.
Further, between described the first container for storing liquid and described the second container for storing liquid, through toothed gear pump, be connected.
A kind of high vacuum continuous draining method of using said apparatus comprises the following steps:
, the xenthophylls finished product that generates under 0～100Pa of short-path evaporator, enter the first container for storing liquid after heat exchange;
(2), adopt toothed gear pump that the xenthophylls in the first container for storing liquid is delivered in the second container for storing liquid;
, xenthophylls is in the second container for storing liquid bottom deposition, through Send out pump, export.
Compared with prior art, the present invention has the following advantages: can guarantee the xenthophylls continuous draining, and need not break sky, can not cause the fluctuation of system vacuum degree, reduce the load of vacuum pump, be applicable to production continuously in enormous quantities.
The accompanying drawing explanation
Fig. 1 is device of the present invention and flowage structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection scope of the present invention.
A kind of high vacuum continuous liquid-discharging device as shown in Figure 1, comprise short-path evaporator 1, the first container for storing liquid 3, the second container for storing liquid 4, vacuum apparatus 5 and interchanger 2, the concentrated solution outlet of described short-path evaporator 1 is communicated with described the first container for storing liquid 3 through described interchanger 2, described the first container for storing liquid 3 is communicated with described the second container for storing liquid 4, and described the second container for storing liquid 4 all is communicated with described vacuum apparatus 5 with described short-path evaporator 1; On described the first container for storing liquid 3 arrangement height, lower than described the second container for storing liquid 4, described the second container for storing liquid 4 bottoms are provided with Send out pump.Between described the first container for storing liquid 3 and described the second container for storing liquid 4, through toothed gear pump, be connected.
Xenthophylls finished product under high vacuum after molecular distillation enters in the first container for storing liquid 3 of its bottom, increase a set of the second container for storing liquid 4 above the first container for storing liquid 3, vacuum tightness and the first container for storing liquid 3 Vacuum Balances, the xenthophylls finished product is got in the second container for storing liquid 4 by toothed gear pump.In the second container for storing liquid 4 bottoms, a toothed gear pump is installed, after lutein extract is filled the pump housing in the deadweight situation, is opened toothed gear pump, by the xenthophylls finished product squeeze in the normal pressure finished pot, carry out filling.
The Vacuum Balance of the first container for storing liquid 3 and the second container for storing liquid 4, the first container for storing liquid 3 liquid are squeezed in the second container for storing liquid 4 by toothed gear pump, and the second container for storing liquid 4 liquid are squeezed into finished pot after in the deadweight situation, the second container for storing liquid 4 lower tooth wheel pumps being filled.The resistance that pump overcomes vacuum when beating liquid is little, does not need brokenly blank operation just liquid to be beaten away.It is empty that this operating method does not need brokenly, can not cause vacuum pump moment to meet increase, the fluctuation of system vacuum degree.
Specific operation process is:
1, in the situation that vacuum tightness 0-100Pa xenthophylls mixing oil through molecular distillation, the xenthophylls finished product of output flows into the first container for storing liquid of bottom, the first container for storing liquid internal vacuum and molecular distillation balance.
2, increase a set of the second container for storing liquid, vacuum tightness and the first container for storing liquid Vacuum Balance above the first container for storing liquid; Use toothed gear pump that the first container for storing liquid Lutein finished product is squeezed in the second container for storing liquid.
3, a toothed gear pump is installed in the second container for storing liquid container for storing liquid bottom, after the xenthophylls finished product is filled pump under the deadweight state, opens toothed gear pump, the xenthophylls finished product is squeezed into to non-pressure vessel filling.
Must ensure the effect that certain liquid level plays fluid-tight in the first container for storing liquid and the second container for storing liquid, during continuous draining, the system vacuum degree is not received impact.
