Abstract
The invention discloses a spray drying method and a device thereof, comprising: a screw extrusion bulking machine is introduced into a spray drying system, the screw extrusion bulking machine is connected with an airflow spray head, the material enters from the inlet of the screw extrusion bulking machine, the material is heated, mixed and conveyed by the screw extrusion bulking machine, the material is atomized and blown out through the airflow spray head by the high pressure air, and the material is cooled and dried by the cold air from an aerator. Compared with the prior art, the method and the device of the invention has higher calorific efficiency, can adapt various natural glues like gelling starch, modified starch, collagen and algin with low water content and high degree of viscosity, simplifies the preprocess device before spray drying, simplifies process, saves investments, greatly enhances production efficiency, and simultaneously has compatibility to the traditional process.
Description
One, technical field
The present invention relates to a kind of spray drying process and equipment thereof, be applicable to the industries such as food, chemical industry, medicine, feed.
Two, background technology
Generally by formations such as air blast, air cleaner, air heater, spray tower, cyclone separator (or sack cleaner), air-introduced machine, dehvery pumps, connected mode is as follows for spray drying system:
Spray-drying mainly contains centrifugal spray, press atomization and three kinds of modes of air-stream spraying, front two kinds more commonly used at present.Heat medium is generally used air, inert gas; The thermal source presentation mode mainly contains Steam Heating, electrical heating, hot-blast stove heating etc.Current spray drying technology has common characteristics: temperature of charge is lower, hot blast temperature is higher, utilizes both temperature difference and hot blast humidity unsaturated, conducts heat between material and the hot blast, mass transfer, reaches the effect of dried material.Because existing spray-drying all is to adopt air is heated, and by the indirect mode of hot air material, therefore, has the problem that production efficiency is low, heat utilization rate is low, equipment investment is expensive again.Especially to the raw material of high viscosity or high solid content in heating, the dry run of carrying, the problem that production efficiency is low is just more outstanding.
Three, summary of the invention
The purpose of this invention is to provide a kind of spray drying process and equipment thereof, solving the dry problem of high viscosity, high solid content material, and then reach the effect that takes full advantage of the energy, reduce cost, raises the efficiency.
The technical solution used in the present invention is: drying system equipment comprises air blast, air cleaner, air heater, spray tower, cyclone separator (or sack cleaner), air-introduced machine and dehvery pump, the present invention replaces dehvery pump with the screw extrusion machine, the screw extrusion machine is connected with the air-stream spraying head, material is entered by the entrance of screw extrusion machine, finish heating to material by the screw extrusion machine, mix, carry, finish atomizing to material by the air-flow shower nozzle by pressure-air, ejection, the cold wind that is flowed by air blast to air-introduced machine is finished the cooling to material, dry.
In general, the screw extrusion function is about the heating material to 150 ℃, even higher; Pressure energy reaches tens air pressure even tens air pressure.Such material, because and have the huge temperature difference and pressure reduction between the cold wind, strong mass exchange (moisture) and exchange heat can occur after both contacts, material can be finished rapidly dry run.
Drying system of the present invention is connection device in the following manner:
Method of the present invention is that material is directly heated, and air generally need not heating, even can precooling.Certainly, if the screw extrusion machine is only finished mixing, conveying to material, and do not heat, can carry out equally conventional spray-drying operation with hot blast.
The present invention has used the screw extrusion technology.We know that the screw extrusion technology is present one of the most energy-conservation, efficient food-processing method; And the air-stream spraying technology is one of the most effective method that solves the high-viscosity material drying.These two kinds of methods combine, and can effectively solve the difficult problem such as heating, conveying, drying of high-viscosity material.
The present invention compares with conventional method: the first, and the thermal efficiency is higher; The second, can adapt to the material that various water content are low, viscosity is high, such as various natural glue classes such as ripe starch, converted starch, collagen, algins; The 3rd, simplify the pre-processing device before the spray-drying, such as heating tank, blending tank, conveyer, conveyance conduit etc., not only simplified technique, but also saved investment, can also greatly enhance productivity; Four, traditional process had compatibility.
Four, description of drawings
Fig. 1 is the structural representation that screw extrusion machine of the present invention is connected with the air-stream spraying head;
Fig. 2 is the structural representation of screw extrusion machine and the another kind of connected mode of air-stream spraying head.
Five, the specific embodiment
Replace dehvery pump as apparatus for feeding with the screw extrusion machine, and the screw extrusion machine is connected with the air-stream spraying head of spray tower.Screw extrusion machine 1 is made of drive 3, auger 4 and heater 5; Air-stream spraying head 2 has front high-pressure pipe 6 and rear high-pressure pipe 7.After material is entered by screw extrusion machine 1 entrance, transmit by auger 4, again by heater 5 heating, be sent to the air-stream spraying head 2 of connection by outlet, material is dispelled, is sprayed by high pressure draught, air blast is blown into the cold wind of spray tower and material obversion, the heat exchange of heating by air cleaner, and dry material is collected by cyclone separator or cloth bag separator.The entrance of air-stream spraying head 2 can be positioned on the fog-spray nozzle sidewall, screw extrusion machine 1 and 2 vertical connections of air-stream spraying head, and material enters 90 ° of fog-spray nozzle rear steerings, is dispelled and transfers out from high- pressure pipe 6,7 pressure-air.The entrance of air-stream spraying head 2 also can be positioned at the fog-spray nozzle afterbody, and screw extrusion machine 1 connects with air-stream spraying head 2 levels, and the material that enters the air-stream spraying head is dispelled, sprays by high- pressure pipe 6,7.
