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 andthe 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 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, preceding 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 a common characteristic: 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, the heat energy 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,, and then reach the effect that makes full use of the energy, reduces investment, raises the efficiency with the dry problem of solution high viscosity, high solid content material.
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 bulking machine, the screw extrusion bulking machine is connected with the air-stream spraying head, material is entered by the inlet of screw extrusion bulking machine, finish heating by the screw extrusion bulking machine to material, mix, carry, finish atomizing by the air-flow shower nozzle by pressure-air to material, ejection, the cold wind that is flowed by air blast to air-introduced machine is finished the cooling to material, dry.
In general, the expanded function of screw extrusion is heated to material about in the of 150 ℃, even higher; Pressure can reach 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 take place after both contacts, material can be finished dry run rapidly.
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,, and do not heat, can carry out conventional spray-drying operation equally with hot blast if the screw extrusion bulking machine is only finished mixing, conveying to material.
The present invention has used the screw extrusion puffing technique.We know that the screw extrusion puffing technique is the most energy-conservation at present, one of food-processing method efficiently; And the air-stream spraying technology is one of efficient ways that solves the high-viscosity material drying.These two kinds of methods combine, and can solve the difficult problem such as heating, conveying, drying of high-viscosity material effectively.
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, as heating tank, blending tank, conveyer, conveyance conduit etc., not only simplified technology, but also saved investment, can also enhance productivity greatly; Four, traditional process had compatibility.
Four, description of drawings
Fig. 1 is the structural representation that screw extrusion bulking machine of the present invention is connected with the air-stream spraying head;
Fig. 2 is the structural representation of screw extrusion bulking 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 bulking machine, and the screw extrusion bulking machine is connected with the air-stream spraying head of spray tower.Screw extrusion bulking machine 1 is made of drive 3, auger 4 and heater 5; Air-stream spraying head 2 has preceding high-pressure pipe 6 and back high-pressure pipe 7.After material is entered by screw extrusion bulking machine 1 inlet, 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 inlet of air-stream spraying head 2 can be positioned on the fog-spray nozzle sidewall, and screw extrusion bulking machine 1 turns to 90 ° with 2 vertical connections of air-stream spraying head, material after entering fog-spray nozzle, is dispelled and transfers out by the pressure-air from high-pressure pipe 6,7.The inlet of air-stream spraying head 2 also can be positioned at the fog-spray nozzle afterbody, and screw extrusion bulking 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.
