Abstract
The invention discloses a hollow granulation device which comprises a storage tank, a pump, a heat exchanger, a liquid flow meter, a first check valve, a gas storage tank, a gas flow meter, a second check valve, a first mixer, a high pressure pump, a second mixer, a spray drying tower, a first valve, a second valve, a thermometer, a first pressure gauge, a second pressure gauge, a third valve and a fourth valve. Before spray drying, liquid is mixed with inert gas and is introduced into the high pressure pump, the gas is acutely compressed under the action of the high pressure pump and is uniformly mixed in the liquid by the mixer, and then, the liquid is introduced into the spray tower; and when the liquid is atomized, the gas in each fog drop fully volatilizes and forms a gas protection layer on the surface of the fog drop. Thus, the invention effectively controls the generation of oxidation reactions and the volatilization of aromatic substances, and reserves the original tea quality of the instant tea powder. Simultaneously, the obtained tea powder is in the shape of a hollow granule, and the fluidity and the solubility are greatly improved.
Description
Technical field
The present invention relates to a kind of spray-drying installation, relate in particular to a kind of device of hollow granulation.
Background technology
In the current spray drying device, no matter be centrifugal spray-drying or press spray drying, when producing instant tea powder, need spray-dired millet paste directly to enter and form vaporific drop in the spray tower, carry out with hot-air in the tower that the moisture in the droplet is evaporated rapidly behind the convective motion, what arrive the spray tower bottom is the instant tea powder of solid shape.In this process, active ingredient in the droplet is easily by high-temperature oxydation and brown stain, and the volatilization that wherein material of low volatilization point such as essence also can be a large amount of and losing, with these two kinds of instant tea powders that method obtains, be that soup look, fragrance or flavour all can produce great change, lose the due quality characteristic of former tea.
Summary of the invention
The deficiency that can change for the quality characteristic that overcomes instant tea powder in spray-drying process, the invention provides a kind of device of hollow granulation, use the instant tea powder that this device obtains, in outward appearance still is that interior quality has all obtained effective improvement, especially the color, smell and taste that kept instant tea powder make it have the characteristic of former tea.
Technical scheme of the present invention is: a kind of device of hollow granulation, it comprises: storage tank, pump, heat exchanger, fluid flowmeter, first check-valves, gas reservoir, gas flowmeter, second check-valves, first blender, high-pressure pump, second blender, spray drying tower, first valve, second valve, thermometer, first Pressure gauge, second Pressure gauge, the 3rd valve, the 4th valve.Wherein, described storage tank outlet links to each other with pump inlet, pump discharge wherein one the tunnel connects behind first valve and links to each other with storage tank upper end import, form the loop, another road of pump discharge connects heat exchanger successively, the 4th valve, fluid flowmeter, first check-valves, thermometer, link to each other with the place, liquid inlet of first blender behind first Pressure gauge, gas reservoir connects second valve successively, gas flowmeter, second check-valves, the 3rd valve, gas access with first blender behind second Pressure gauge links to each other, the outlet of first blender links to each other with the import of high-pressure pump, and the high pressure delivery side of pump links to each other with spray tower after connecting second blender.
The invention has the beneficial effects as follows: before spray-drying; liquid with enter high-pressure pump after inertness gas (carbon dioxide or nitrogen) mixes; under the effect of high-pressure pump; gas is entered spray tower by violent compression back by the blender mixing in liquid; in the moment that liquid is atomized; the gas of droplet the inside fully volatilizees and forms one deck gas shield layer on the droplet surface; the generation of oxidation reaction and the volatilization of fragrance matter have been controlled effectively; make the quality characteristic of instant tea powder Central Plains tea obtain reservation; the tea powder that obtains simultaneously is the hollow particle shape, and mobile and dissolubility improves greatly.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
As shown in Figure 1, the device of hollow granulation of the present invention comprises: storage tank 1, pump 2, heat exchanger 3, fluid flowmeter 4, first check-valves 5, gas reservoir 6, gas flowmeter 7, second check-valves 8, first blender 9, high-pressure pump 10, second blender 11, spray drying tower 12, first valve 13, second valve 14, thermometer 15, first Pressure gauge 16, second Pressure gauge 17, the 3rd valve 18, the 4th valve 19.
