Abstract
The invention discloses a microwave vacuum drying method for a concentrated solution of a thermosensitive plant. The method comprises the following steps: 1) extraction of a concentrated solution of a thermosensitive plant; and 2) dehydration of the concentrated solution of the thermosensitive plant, wherein the step 2) comprises, according to the area of a spread material, a sub-step of carrying out dehydration with strong microwaves having an intensity of 4 W/cm<2> when water content is greater than 40%, a sub-step of carrying out dehydration with medium microwaves having an intensity of 2 W/cm<2> when water content is 30 to 40%, a sub-step of carrying out dehydration with slightly weak microwaves having an intensity of 0.5 W/cm<2> when water content is 25 to 30% and a sub-step of carrying out refined extraction with weak microwaves having an intensity of 0.1 W/cm<2> when water content is 20 to 25% to improve condensation purity of the concentrated solution of the thermosensitive plant and prevent excessively low water content and to finally obtain the concentrated solution of the thermosensitive plant with water content of 20 to 25%. With the microwave vacuum drying method provided by the invention, the plant is enabled to form condensed cream, and the advantages of simple processing and a good effect are obtained.
Description
Technical field
The present invention relates to a kind of thermal sensitivity plant concentrate vacuum microwave drying method.
Background technology
Tealeaves is one of worldwide three big beverages, also is called the beverage of 21st century, and various countries, the world today drink just flourish the popularization of tealeaves.Then, existing tealeaves is mainly still packed and is drunk with tealeaves form originally, can not form paste with fixed attention.
Summary of the invention
It is simple that the technical problem that the present invention will solve provides a kind of processing, effective, can form the thermal sensitivity plant concentrate vacuum microwave drying method of paste with fixed attention.
For addressing the above problem, the present invention adopts following technical scheme: a kind of thermal sensitivity plant concentrate vacuum microwave drying method may further comprise the steps:
1), extracts thermal sensitivity plant concentrate;
2), thermal sensitivity plant concentrate is dewatered, may further comprise the steps: according to the stone area,
A, water content were used strong microwave dehydration greater than 40% o'clock, and microwave intensity is at 4W/cm
2
B, water content when 30%-40%, with in microwave dehydration, microwave intensity is at 2W/cm
2
C, water content are when 25%-30%, and with time weak microwave dehydration, microwave intensity is at 0.5W/cm
2
D, water content for further improving the concentrated purity of thermal sensitivity plant concentrate, prevent that simultaneously moisture content is low excessively when 20%-25%, carry out essence with weak microwave and carry, and microwave intensity is at 0.1W/cm
2, finally make the water content of thermal sensitivity plant concentrate at 20%-25%.
Further, the said the 2nd) in the dehydration in step, temperature is at 50 degree-80 degree, and dewatering time is in 2 hours, and vacuum is below 0.1.
Further, said plant is a tealeaves, finally is made for tealeaves and coagulates cream.
The beneficial effect of thermal sensitivity plant concentrate vacuum microwave drying method of the present invention is: it adopts the vacuum microwave drying method through technique scheme, plant is formed coagulate paste, and its processing is simple, effective.
The specific embodiment
A kind of thermal sensitivity plant concentrate vacuum microwave drying method of the present invention may further comprise the steps:
1), extracts thermal sensitivity plant concentrate;
2), thermal sensitivity plant concentrate is dewatered, may further comprise the steps: according to the stone area,
A, water content were used strong microwave dehydration greater than 40% o'clock, and microwave intensity is at 4W/cm
2
B, water content when 30%-40%, with in microwave dehydration, microwave intensity is at 2W/cm
2
C, water content are when 25%-30%, and with time weak microwave dehydration, microwave intensity is at 0.5W/cm
2
D, water content for further improving the concentrated purity of thermal sensitivity plant concentrate, prevent that simultaneously moisture content is low excessively when 20%-25%, carry out essence with weak microwave and carry, and microwave intensity is at 0.1W/cm
2, finally make the water content of thermal sensitivity plant concentrate at 20%-25%.
Wherein, the said the 2nd) in the dehydration in step, temperature is at 50 degree-80 degree, and dewatering time is in 2 hours, and vacuum is below 0.1.In the present embodiment, temperature is at 50 degree, and said plant is a tealeaves, finally is made for tealeaves and coagulates cream.
The beneficial effect of thermal sensitivity plant concentrate vacuum microwave drying method of the present invention is: it adopts the vacuum microwave drying method through technique scheme, plant is formed coagulate paste, and its processing is simple, effective.
Below the present invention is done a detailed description, the above is merely the present invention's preferred embodiment, when can not limiting practical range of the present invention, promptly allly does impartially to change and modify according to the application's scope, all should still belong in the covering scope of the present invention.
