Abstract
The invention relates to an atomizing and pelletizing device which is provided with a drying tower and a cyclone separator, wherein the top of the drying tower is provided with an atomizer, the bottom of the drying tower is provided with an internal fluidized bed, and a discharging hole of the internal fluidized bed is connected with an external fluidized bed through a feeding pipe. By combining a fluidized bed drying technology and a atomizing drying technology, the invention ensures that particle shape and size are easy to control, a drying process is completed while lower powder temperature can be kept, thus the atomizing and pelletizing device can be applied to drying forming of a thermal-sensitive product. Fine powder collected by the cyclone separator is recycled to the drying tower, so that concentration of powder in the drying tower is increased, the powder and atomized liquid drops which are not completely dried generate agglomeration and pelletizing, so that the dust content of the atomizing and pelletizing device is reduced to be minimum, material loss is greatly reduced, yield is increased, and cost is saved.
Description
Technical field
The present invention relates to a kind of spraying granulation device.
Background technology
The spraying granulation device is a kind of multi-functional special equipments such as spray-drying, granulation that integrate, and in food, pharmacy, agriculture chemical manufacture, is widely used.The spraying granulation device 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 earlier by preheating, and through fog-spray nozzle material is atomized; The material of atomizing in hothouse after, moisture is by rapidly evaporation, the material fine powder of shaping is collected; Can carry out next step necessary processing, overall process need not artificial treatment.
Yet the product cut size of this apparatus processing 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, causes 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 like processing such as the processing of amino acid, yeast, vegetable fat powder, milk, plant or Chinese herbal medicine extracting concentrate etc.
Summary of the invention
The object of the present invention is to provide a kind of the loss late of processing materials is reduced significantly, product is produced the efficient height, powder dust content few, can the free flowing granule product, and can when keeping low powder temperature, accomplish the drying process with atomizing of dry run.
The technical scheme that realizes the object of the invention is: the present invention has drying tower and cyclone separator, and said drying tower top is provided with atomizer; Said drying tower bottom is provided with built-in fluid bed, and the logical charge tube of the discharging opening of built-in fluid bed connects external fluid bed.
Above-mentioned built-in fluid bed and external fluid bed are orifice plate or mesh structure fluid bed.
The present invention has following characteristics:
(1) the present invention has two fluid beds; Built-in fluid bed can be delivered to external fluid bed by the logical charge tube of discharging opening with shaping and granularity and the satisfactory material particles of humidity and carry out further processed, and unfashioned material fine powder, the material particles that particle diameter is too small and compactness is not enough 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 among the present invention is arranged on the drying tower middle part, and the material dust that cyclone separator is collected directly gets into and carries out granulation process in the drying tower, need not to atomize through atomizer once more, practices thrift cost.
(4) be provided with antiseized wall device in the drying tower of the present invention; This device is pressed close to the inwall place and is constantly stirred in spray-drying process; Prevent the generation of the sticking wall of wet stock; The compressed air that sprays in the fumarole of bull stick simultaneously can be clean with the drying tower inner wall blowing, solved the sticking wall problem of material, and is reasonable in design ingenious.
Description of drawings
For content of the present invention is more clearly understood, below basis specific embodiment and combine accompanying drawing, the present invention is done further detailed explanation, wherein
Fig. 1 is a structural representation of the present invention.
The specific embodiment
See Fig. 1, the present invention has drying tower 1 and cyclone separator or bag hose 2, and the air outlet on drying tower 1 top is connected with the import of cyclone separator through pipeline; Drying tower 1 top is provided with atomizer 3; The bottom is provided with built-in fluid bed 4; The logical charge tube 5 of the discharging opening of built-in fluid bed 4 connects external fluid bed 6; Built-in fluid bed 4 is orifice plate or mesh structure fluid bed with external fluid bed 6, has built-in fluid bed orifice plate 41 and external fluid bed orifice plate 61 respectively, and built-in fluid bed 4 all is connected with air line 8 with external fluid bed 6 bottoms; Be provided with antiseized wall mechanism 7 in the drying tower 1; Said antiseized wall mechanism 7 has the bull stick 71 that matches with drying tower 1 inner wall shape and drives the driven unit 72 of bull stick 71 near move in the drying tower 1; Said bull stick 71 is a hollow tube; Its lower end is connected with compressed air, and body is provided with row's fumarole near a side of drying tower 1 inwall; The feedback outlet of cyclone separator 2 is arranged on the middle part of drying tower 1.
When spraying granulation device of the present invention is worked; Heated material liquid is sprayed onto in the drying tower 1 through atomizer 3 atomizings by feed pipe 9; Atomized drop moisture in drying tower is formed material particles by evaporation rapidly, drops down onto afterwards in the built-in fluid bed 4; Through getting into external fluid bed 6 fluidized dryings and cooling by the logical charge tube 5 of discharging opening after the fluidized drying of built-in fluid bed 4; Because the blowing of built-in fluid bed 4 bottom hot-airs, make the material dust of carrying secretly in the material particles rise to drying tower 1 middle part with hot-air, contact the formation material particles with the atomized drop of ejection in the fog-spray nozzle 3; And also can leading to charge tube, the material dust in material dust in the external fluid bed 6 and cyclone separator or the bag hose 2 gets into again 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; And bull stick 71 move in the drying tower 1 of the driving lower edge of driven unit 72 of antiseized wall mechanism 7; Prevent the generation of the sticking wall of wet stock; Bull stick 71 is along in the drying tower 1 move the time, and the compressed air in bull stick 71 bodys blows out from fumarole, can the drying tower inner wall blowing is clean; Solve the sticking wall problem of material, reduced the loss of material.
