Technical Field

The present invention relates to dryers, and more particularly, it relates to a pulsed vacuum dryer system.

Background

The desiccator is often used for carrying out drying process for the medicinal material, including establishing the drying cabinet in the drying cabinet, be equipped with the shelf on the drying cabinet, it is mainly through arranging the medicinal material in on the charging tray, arrange the charging tray in the shelf again, the shelf is equipped with the multilayer, because need can circulate the heat source and heat the medicinal material in the shelf, but every layer of shelf all is the relative independence and intakes, so appear each layer of shelf uneven problem of intaking very easily, thereby influence the holistic heating effect of desiccator, only heat through the shelf in addition, the moisture of medicinal material becomes steam and still stops in the drying cabinet, drying efficiency has been reduced.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a pulse vacuum drying machine system, which solves the problem that water vapor of medicinal materials stays in a drying box body.

In order to achieve the purpose, the invention provides the following technical scheme:

a pulse vacuum drier system comprises a drying box body,

A vacuum device for vacuumizing the interior of the drying box body,

The heating device is used for heating the interior of the drying box body, a movable drying trolley is arranged in the drying box body, and a pulse puncturing device is arranged on the drying trolley;

the drying trolley comprises a hollow shelf for placing materials, a circulating heating medium is introduced into the shelf, the pulse puncturing device comprises a compressed air storage tank, a pulse valve and a plurality of nozzles which are detachable from the drying trolley and are arranged outside the drying box, the nozzles all eject clean compressed air or inert gas towards the shelf in a horizontal pulse type intermittent mode, the compressed air storage tank is communicated with the nozzles through an air pipe, and the pulse valve is installed on the air pipe.

The invention is further configured to: the vacuum device comprises an upper vacuum pipeline and a lower vacuum pipeline, the upper vacuum pipeline comprises a condenser, a vacuum buffer tank, a Roots vacuum pump and a first water circulation vacuum pump which are sequentially connected, and the condenser is communicated with an upper vacuum outlet arranged at the top of the drying box body through a vacuum pipe;

the lower vacuum pipeline comprises a second water circulation vacuum pump, the second water circulation vacuum pump is communicated with an air extraction opening formed in the drying trolley through a vacuum pipe, the air extraction opening and the nozzle are located on the same horizontal plane, and gas sprayed out of the nozzle is extracted through the air extraction opening.

The invention is further configured to: the heating device comprises a boiler, and the boiler is communicated with the shelf through a water pipe.
