Abstract
The said drying method specially for producing dry fresh spirulina powder is a multiple-fluid spray drying process. Compared with available drying method, the said method has a dry spirulina powder yield of 1.5-2 times higher and a drying cost and power consumption of 30% lower.
Description
What the inventive method related generally to is a kind of method of production and processing fresh Spirulina dry powder.This processing method is under the prerequisite of not destroying the fresh spirulina cell body, removes fresh Spirulina appearance moisture content at first as much as possible, and makes the interior moisture content of cell still remain on 75-85% simultaneously.At total moisture content is 85-90%, under the mobile very poor situation of fresh Spirulina, still can make its atomizing back dry rapidly, and can keep unique processing method of the nutrition that former fresh Spirulina contains fully.
At present the drying means of the fresh Spirulina that uses in the U.S., Japan, Mexico and other country that produces spirulina is, adopt advanced at present centrifugal spray drying method and pressure spray dryer method, the method that this quilt generally adopts is that its total moisture content is remained on more than 95%, and have under the prerequisite of good flowability, carry out centrifugal spray and pressure spray dryer then.More than the limitation of these two kinds of drying means be: it can not make fresh spirulina be lower than 95% at total moisture content, otherwise fresh Spirulina is difficult to carry out spray-drying because of flowability is too poor, and behind 95 kilograms of moisture content of every evaporation, can only obtain the fresh Spirulina dry powder of 5kg.
The present invention has then overcome the poor efficiency and the limitation of above two kinds of methods fully to the drying means of fresh Spirulina.
The present invention adopts multithread spray body seasoning.This method is under the prerequisite that guarantees the fresh Spirulina dry powder quality, has accomplished raising output, energy savings and reduces production costs.
This method can be removed the water that attaches of spirulina cells outer surface as much as possible under the prerequisite of not destroying the fresh spirulina cell body, the fresh Spirulina of this moment becomes " fish is frozen " shape fresh Spirulina mud.The multithread spray body drying system that the inventive method adopts can make the fresh Spirulina mud of " fish is frozen " shape, is sent into drying tower very easily, and is atomized in the air-flow that 195-210 degree Celsius rotates at a high speed and rapid drying.This desirable process has reached every evaporation 85-90kg moisture content, can produce the purpose of the fresh Spirulina dry powder of 15-10kg.
For processing method of the present invention is described in detail in detail, can learn in conjunction with the accompanying drawings.
In the process chart of accompanying drawing one, at first be after the fresh Spirulina in the production pond is cleaned, dewaters through sieving, when making fresh spirulina become similar " fish is frozen " shape algae mud, they are sent in the multithread spray body drying tower incessantly continuously carry out drying again.
Accompanying drawing two is front fundamental diagrams of multithread spray body drying tower.The diameter of multithread spray body drying tower is 1.3m-3m as seen from the figure, and body of the tower is high between the 6m-15m (can select for use arbitrarily according to the output size).Cat head at drying tower (3) is connected to a blower fan (1), when temperature is controlled between 195-215 ℃, under the effect of blower fan (1), enters in the dry body of the tower (4) through guiding distribution plate (2), does rapid rotation descending motion from top to bottom." fish is frozen " shape fresh Spirulina mud after concentrating is sent into the multithread body nozzle (5) that is installed in the drying tower (4) by charging line, jet atomization rapidly in hot-air then.The fresh Spirulina powder that has been atomized dehydrates rapidly in descending motion again along with the thermal current of rotation at full speed.Enter gas, powder separator (6) after the outlet of fresh spirulina powder drying tower bottom, the fresh Spirulina dry powder after the separation is admitted to storage warehouse (7) packed products, and separated humid air then is discharged in the atmosphere.
Embodiment
Get some jin of fresh spirulinas through filtering, wash and making its pH value reach at 7 o'clock, just send them to inspissator and dewater.Continuously send into multithread body nozzle in the drying tower concentrating the good fresh spirulina mud of water content about 85%, through the feeding in the nozzle, primary atomization, secondary-atomizing, after the technical process of three atomizings, in tower in the rotary descending motion from top to down of 195-215 degree air-flow Celsius, can make fresh Spirulina mud with the fresh Spirulina dry powder of output 3kg-15kg per hour, and can guarantee the natural nutrition composition of bright spiral shell algae, the moisture content of algae powder can be controlled in 5-10%, controllable granularity is between 60～200 orders, and appearance color is a bottle green.After the gas of the fresh Spirulina dry powder drying tower bottom after these are dried, powder separator separate, can vacuum-packed finished product.
The fresh Spirulina dry powder of producing with the inventive method has kept the high protein of the 60-72% that former fresh Spirulina contains and various trace elements and other nutrition of vitamin and other needed by human fully.Steady quality in finished product storage life 18 months does not have corrupt.
The inventive method has following evident characteristic:
Compare with external prior art, have at evaporation moisture content, consume in the identical situation of thermal source, fresh Spirulina powder yield rate improves one to two times, and comprehensive energy consumption reduces more than 30%, thereby has reduced the cost of fresh Spirulina drying.
Compare with the external centrifugal spray drying that adopts at present and/or two kinds of equipment of pressure spray dryer fresh Spirulina, the advantage of using multithread spray body drying tower of the present invention then is simple in structure, the high efficiency of equipment own, the flour extraction height, power consumption is few, the maintenance cycle is longer, and is easy to maintenance, and maintenance cost is low.
