Abstract
A device for preventing aleuron from sticking to wall and coking in a spray drying tower belongs to the technical field of food and drug processing machineries and particularly relates to an 'air curtain' device added on the upper end of a spray tower cone body of an existing spray drying tower in domestic and oversea markets. The 'air curtain' device can prevent dried food (drugs) from contacting with the wall of the spray drying tower, thereby preventing products from sticking to the tower wall and coking. One to three 1-millimeter apertures serving as hot-air conducts are arranged on the top of the spray tower and coil around the wall of the cylindrical tower, so that the 'air curtain' device is formed. During production, hot air blows into the apertures vertically to form the 'air curtain', thereby preventing food (drug) sprayed out from being contacted with the wall of the spray tower and preventing the aleuron from sticking to the wall and coking.
Description
Technical field
The utility model belongs to food medicine process equipment field, specifically relates to a kind of device that prevents easily sticking wall of spray drying tower and aleuron coking.
Background technology
Spray-drying is to adopt atomizer that material liquid is separated into droplet, and obtains a kind of drying means of product with hot gas (air, nitrogen or overheated steam) dry droplet.In the ubiquity dry run, the food that is dried (medicine) adheres to the spray tower wall easily in the at present domestic and international spray drying device.
Chinese patent CN200520010864.8, a kind of tomato meal isolated plant particularly is provided, solved the problem of sticking wall of high production capacity spray-drying tomato meal and aleuron coking, it comprises drying tower, warm-air pipe, heat exchanger, pressure fan, the dedusting dehumidifier, exhaust column, air-introduced machine, cyclone separator, vibrated fluidized bed and vibratory sieve, warp is the 7000-8000 millimeter in the drying tower, high 2500-5500 millimeter, around the straight wall section of drying tower, be provided with cold air cover and pipeline, being provided with interior angle in the drying tower bottom is party's awl of 60 degree, single awl bottom is connected to the cold wind disintegrating machine, the cold wind disintegrating machine is connected with vibrated fluidized bed by flexible pipe, pressure fan, air-introduced machine is connected with frequency converter respectively, this device for prolonging the drying process and the time of catsup, and can adjust temperature at any time, air quantity and air velocity, and rate of drying is fast, and the temperature of drop is lower in the dry run, the drying of suitable especially heat sensitive material can keep the look of tomato meal, fragrant, flavor.CN200620117560.6 has solved the problem of sticking easily wall of conventionally spray-dried device tomato meal and aleuron coking, it comprises drying tower, warm-air pipe, the controllable type heat exchanger, air-heater, air-introduced machine, the dedusting dehumidifier, exhaust duct, the whirlwind pipeline, cyclone separator and vibrated fluidized bed, the drying tower top is connected with warm-air pipe, be provided with rectifier at the drying tower top, below rectifier, be provided with pressure type atomizing gun and pressure distributor, be provided with the Venturi tube feeder in the drying tower middle and upper part, be provided with cold wall air pipe line at the drying tower middle part, be symmetrical arranged 2 pulse of air bugdusters in drying tower straight arm section bottom, it is 60 ° bipyramid that drying tower bottom is provided with interior angle, the bipyramid bottom is connected with 1# vibrations fluid bed by flexible pipe, be connected to 2# vibrations fluid bed under the 1# vibrations fluid bed, this device has the characteristics of wink-dry, the drying of suitable especially heat sensitive material can keep the look of tomato meal, fragrant, flavor.CN200710022624.3 discloses a kind of double-cone shape spray-drying tower body.It comprises the tower body, and this tower body is a cylinder, and it is erects the shape layout, and its underpart is up big and down small conical section.The conical section lower end that is characterized in tower body bottom is connected to up big and down small lower cone, and the upper and lower part of this lower cone has exhaust outlet and discharge gate respectively.Wherein, the diameter of hypocentrum upper end is greater than the lower end diameter of the conical section of tower body body bottom, and seals mutually between the conical section of lower cone upper end and tower body bottom.This double-cone shape spray-drying tower body, cost of investment is low, and the scope of application is unrestricted.Be applicable to liquid materials such as biology, medicine and food are carried out spray drying treatment.Its body of the tower of application number CN200620093695.3 is a cylindrical tube, the drive nozzle of feed liquid pipe and atomizing usefulness is installed at drying tower cylindrical shell internal upper part, have hot-air mouth in drying tower cylindrical shell bottom, top has discharging opening, it is characterized in that the drying tower cylindrical shell up and down two ends be the conically shaped structure, the relative position in drying tower cylindrical shell both sides is equipped with two vibrating motors that incline direction is opposite; Be equipped with filter at the slower conical tube port, on the filter of slower conical tube, be equipped with inert media.The utility model adopts double oscillating electromotor, has prevented the adherent and bonding phenomenon of material.The adding of inert media has increased dry tenacity, has accelerated rate of drying, has shortened drying time, has improved the thermal efficiency; And played the effect of supporting, fragmentation and reinforcement rate of drying, can reduce the size of drying tower cylindrical shell, reduced investment, reduced cost.Can produce continuously, improve drying efficiency.Can dry thermal sensitivity and low-melting rare material.Domestic patent is to relate to and " gas curtain " is installed in the spray tower prevented sticking wall and aleuron device
Summary of the invention
The objective of the invention is to improve product matter, reduce paste cleaning equipment number of times and realize the energy-saving and cost-reducing purpose that is in order to prevent easily sticking wall of spray drying tower and aleuron coking in the spray-drying process.Apparatus of the present invention are that spray tower cone upper end spray tower installs " gas curtain " device on one's body down additional in the spray drying device, and " gas curtain " stops food (medicine) the contact spraying Tata wall that is dried, and guarantees not sticking wall of product and aleuron coking.
Description of drawings:
Accompanying drawing 1 is for preventing the schematic representation of apparatus of easily sticking wall of spray drying tower and aleuron coking, and 1 is the spraying body of the tower among the figure, and 2,3 are air curtain device (having the warm-air pipe of the line of rabbet joint, the wide seam of opening on the warm-air pipe of 1-3 road 1mm), and 4 is the hot blast import, and 5 is sprayer unit.
Accompanying drawing 2 is the spray tower schematic internal view, and 1,2,3 is identical with accompanying drawing 1 among the figure.
The specific embodiment
A kind of device that prevents sticking wall of spray-drying and aleuron coking, during production, sprayer unit 5 is with the spraying in spraying body of the tower 1 of required spray-dired liquid, there is the hot-air (producing hot blast introduces) of certain pressure to enter air curtain device 2 from hot blast import 4, blow vertically in 3, form " gas curtain ", the food of spraying out (medicine) can't contact with spraying body of the tower 1, has realized not sticking wall of spray-drying process and aleuron coking.
