Abstract
The utility model relates to a spray drying device which is provided with a drying tower and a cyclone separator, wherein the top of the drying tower is provided with an atomizer, and the bottom thereof is provided with an external fluidized bed; and the lower end of the external fluidized bed is provided with a discharge hole, and the upper end thereof is connected with the upper side of the cyclone separator by a material pipe. By combining the drying technology and the spray drying technology of the fluidized bed, the particle shape and the size are easily controlled, the drying technique can be completed under the condition of maintaining lower powder temperature, and the spray drying device can be applied to drying and forming heat-sensitive products; and simultaneously, the spray drying device greatly reduces the material loss, improves the finished product ratio and saves the cost.
Description
Technical field:
The utility model relates to a kind of drying device, refers in particular to a kind of spray-drying installation.
Background technology:
Spray-drying installation is a kind of multi-functional special equipments such as spray-drying, granulation that integrate, and is widely used in food, pharmacy, agriculture chemical manufacture.The spray-drying installation of prior art mainly is made up of spray drying tower, atomizer, cyclone separator, firing equipment and air filter unit.Spray-drying process can be processed as fine powder (containing a large amount of dust) with the liquid that pump is carried continuously with nearly all.In order to reduce thermal energy consumption, liquid can be preheated earlier, and by fog-spray nozzle material is atomized, the atomizing material in hothouse after, moisture is evaporated rapidly, the material fine powder of shaping is collected, can carry out next step necessary processing, overall process need not artificial treatment.
Yet this equipment product processed particle diameter is little, narrow particle size distribution, do not form the fine powder more (accounting for more than 50～100%) of particle in the finished product, and material is easy to generate sticking wall problem in the drying tower, cause material loss bigger, product yield is very low, directly has influence on production efficiency of products, quality and energy resource consumption; Simultaneously, because the spray-drying of prior art is just passed through the material convection drying of the convection current of hot-air in the drying tower with atomizing, relative temperature is higher, at some thermally sensitive liquid of processing, there is certain problem in the processing of extracting concentrate etc. as natural colouring matter, amino acid, yeast, milk, plant or Chinese herbal medicine.
The utility model content:
The purpose of this utility model is to provide a kind of the loss late of processing materials is reduced significantly, product is produced the efficient height, powder dust content is few, can the free flowing granule product, and can when keeping low powder temperature, finish the drying process with atomizing of dry run.The technical scheme that realizes the utility model purpose is: the utlity model has drying tower and cyclone separator, described drying tower top is provided with atomizer; It is characterized in that: described drying tower bottom is provided with external fluid bed, external fluid bed lower end is provided with sieving machine and discharging opening, the upside of logical charge tube in upper end and cyclone separator joins, and the cyclone separator lower end is connected to collection powder bucket, and collection powder bucket bottom joins with the drying tower top by discharge valve, material pipe.
The feedback outlet of cyclone separator is arranged on the top of drying tower.
The upside of logical charge tube in the middle part of drying tower and cyclone separator joins, and the cyclone separator upper end is connected with the filter bag device.
The utlity model has following characteristics:
(1) the utility model is provided with external fluid bed, shaping and granularity and the satisfactory material particles of humidity can be discharged by discharging opening, unfashioned material fine powder, the material particles that particle diameter is too small and compactness is not enough enter drying tower by the feed back pipe and can fully contact bonding with liquid droplet once more, form satisfactory particle, it is few to have guaranteed that product contains Dust Capacity, thereby reach the dustless requirement of product, yield rate is higher, and granulating efficiency is good.
(2) owing to spray-drying and fluidized bed drying processing technology be combined in the drying tower carry out, so can in the big excursion of relevant particle size, moisture and drying air temperature, operate drying tower, thereby better control the degree and the effect of particle agglomeration or granulation, the temperature that can guarantee particle in whole dry run remains lower, therefore is particularly suitable for dry thermal sensitivity product.
(3) the cyclone separator feedback outlet in the utility model is arranged on the drying tower top, and the material dust that cyclone separator is collected directly enters and carries out granulation process in the drying tower, and drying effect is better.
Description of drawings:
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment 1:
See Fig. 1, the utlity model has drying tower 1 and cyclone separator 2, drying tower 1 top is connected with the collection powder bucket 5 of cyclone separator 2 bottoms by pipeline; Drying tower 1 top is provided with atomizer 13, the bottom is provided with external fluid bed 3, external fluid bed 3 lower ends are provided with sieving machine 6 and discharging opening, and the upside of logical charge tube in upper end and cyclone separator 2 joins, and the upside of also logical charge tube in the middle part of drying tower 1 and cyclone separator 2 joins; Cyclone separator 2 upper ends are connected with filter bag device 4, and filter bag device 4 upper ends are connected with exhaust blower 14.The cyclone separator lower end is connected to collection powder bucket 5, and collection powder bucket 5 bottoms join with drying tower 1 top by discharge valve 10, material pipe; Discharge valve 10 opposite sides are connected with silencer 9, Roots blower 8, filter 7 successively; Atomizer 13 outsides connect heater 12, air inlet 11 successively.
When spray-drying installation of the present utility model is worked, heated material liquid is sprayed onto in the drying tower 1 through atomizer 13 atomizings by feed pipe, atomized drop moisture in drying tower is evaporated rapidly, form material particles, drop down onto afterwards in the external fluid bed 3, through after the fluidized drying of external fluid bed 3 by the discharging opening discharge, while is owing to external fluid bed 3 bottom hot-airs blowing, make the material dust of carrying secretly in the material particles rise to drying tower 1 middle part, contact the formation material particles with the atomized drop of ejection in the atomizer 13 with hot-air; And in the external fluid bed 3 and the material dust in the drying tower 1 flow back to successively by cyclone separator 2, collection powder bucket 5, discharge valve 10, material pipe and reenter in the drying tower 1, contact the formation material particles with the atomized drop of ejection in the fog-spray nozzle 3, thereby it is few to make that product contains Dust Capacity, has improved the loss late and the production efficiency of processing materials simultaneously.
