Description

Spiral dry distillation device

The utility model relates to a kind of water distilling apparatus, a kind of spiral dry distillation device that extracts aromatic oil from Chinese pepper from the Chinese prickly ash pericarp of definitely saying so.

Aromatic oil from Chinese pepper extracts from the Chinese prickly ash pericarp, and it contains 26 kinds of effective Chemical Composition, is the important source material of mutual industries such as food, change are mutual, medicine, also is the indispensable diet condiment of people's daily life.Experimental results show that the effective Chemical Composition in the aromatic oil from Chinese pepper, do not have vaporization reaction substantially under temperature is lower than normal pressure below 160 ℃, therefore currently used poach distillation extraction aromatic oil from Chinese pepper length consuming time, fuel-displaced few is unsuitable for large-scale production.It is that carrier is planted only at 0.03-0.05MPa mutually with dry distillation that the present invention adopts with steam, under 103 ℃-105 ℃ the pressure and temperature, the effective ingredient in the aromatic oil from Chinese pepper is separated, and the time spent is short, and is fuel-displaced many, is suitable for large-scale production.

The purpose of this utility model is: to provide a kind of be carrier with steam, plant mutually with dry distillation and extract the spiral dry distillation device that aromatic oil from Chinese pepper adopted.

Goal of the invention of the present utility model realizes by implementing following technical proposals:

Spiral dry distillation device is that a kind of roof one end has hopper, connects feeding tube down, and the other end has the profit vapour outlet of tipping condenser, and diapire has an encloses container of material slag outlet.A plate of preventing that has countless eyelets is arranged in the container, the cavity of container is separated into two chambeies up and down, come together in epicoele because there is profit steam to pass the eyelet of preventing on the plate from cavity of resorption, therefore deserve to be called the chamber and be profit vapor collection remittance chamber, and two conveyings that the rotating shaft along continuous straight runs is settled are housed in the cavity of resorption, the spiral conveyer that spice is used, its rotating shaft is by electric motor driving, offer a lot of spouts on the diapire of cavity of resorption, in order to the nozzle on the water vapour pressurizing device is adorned thereon, be equiped with material-loosing apparatus in the hopper, it is unimpeded to be convenient to material, and the feeding tube that is connected on the hopper lower end runs through the epicoele of container, its nozzle directly is opened in prevents on the plate, guarantees that material is directly in the cavity of resorption; Be contained in the wind sheltering feeder in the feeding tube, can suppress the vapour pressure from cavity of resorption effectively, make material unimpeded, the wind sheltering discharger of device in the outlet of cavity of resorption material slag also can suppress the vapour pressure from cavity of resorption effectively, avoids the material leakage; For keeping required temperature in the container, the outer wall of container epicoele is provided with thermal insulation layer.

Essential characteristic of the present utility model is: have the plate of preventing of band eyelet in the container, container cavity is separated into two chambeies up and down; Epicoele is profit vapor collection remittance chamber, and device has the spiral conveyer of rotating shaft along continuous straight runs rotation in the cavity of resorption; The feeding tube that connects under the hopper runs through the container epicoele, and its nozzle directly is opened in prevents on the plate, offers spout on the diapire of container cavity of resorption, and the nozzle that sprays pressurized water steam in the chamber is installed.

It is of the present utility model that to make principle mutually as follows:

Under the driving of motor, augur, material by hopper under the material-loosing apparatus effect through the wind sheltering opening for feed, feeding tube enters the distiller cavity of resorption, and by the flight of spiral conveyer it is stirred slowly and to push backward, steam from boiler is input in the pressurizing device, spray in the distiller cavity of resorption with certain temperature and pressure through nozzle, fully act on material, the volatile aromatic oil molecule that its inside is had breaks through oil vacuole, break away from parent, mixing with water vapor, is carrier with the water vapor, enters the epicoele of distiller by preventing eyelet on the plate, enter condensing chamber through the profit vapour outlet under differential pressure action, water separator deoils behind the cold filtration.

Advantage of the present utility model is: apparatus structure is simple, processing ease, and the distillation time spent is short, the oil yield height, constant product quality is suitable for the mass-producing continuous production.

Accompanying drawing is the utility model structure longitudinal section synoptic diagram.

Mark among the figure: 1 is the distiller container, 2 the plates of preventing for the band eyelet, and 3 is distiller container epicoele, 4 is distiller container cavity of resorption, 5,6 is spiral conveyer, and 7 is hopper, and 8 is material-loosing apparatus, 9 is feeding tube, and 10 are the wind sheltering feeder, and 11 is the profit vapour outlet, 12 are the outlet of material slag, and 13 are the wind sheltering discharger, and 14 is nozzle, 15 for installing the spout of nozzle, and 16 is thermal insulation layer, and 17 is the feeding tube mouth, 18 is the water vapor supercharging device, and 19 is step-down gear, and 20 is electric motor.
