Abstract
The invention provides a preparation method of frozen and dried coffee with baked and ground appearance. The method comprises the following steps: S1. slowly freezing the lower layer part of water extraction liquid of the coffee while the supernatant liquid is basically not frozen; S2. spraying liquid nitrogen onto the upper layer part of the coffee extract liquid to enable the upper layer part to be rapidly frozen; S3. grinding the coffee extract frozen in the S2; and S4. freezing and drying the frozen coffee extract ground in the S3. The frozen and dried coffee prepared by the method has the good baked and ground appearance, and the good flavor of the frozen and dried coffee is maintained.
Description
Technical field
The present invention relates to the preparation method of beverage, be specifically related to a kind of freeze-dried coffee with baking ground coffee outward appearance.
Background technology
Bake ground coffee and have good outward appearance, freeze-dried coffee service, coffee set is for good local flavor.At present also do not have a kind of coffee to possess both advantages simultaneously.
Summary of the invention
The object of this invention is to provide a kind of preparation method of the freeze-dried coffee with baking ground coffee outward appearance, solve one or more in above-mentioned prior art problem.
According to an aspect of the present invention, provide a kind of preparation method of the freeze-dried coffee with baking ground coffee outward appearance, comprise the following steps:
S1, by the underclad portion slow freezing of the water extract of coffee, simultaneously supernatant liquid not yet freezes substantially;
S2, the top section of coffee extract is sprayed to liquid nitrogen, make its quick freezing;
S3, the coffee extract freezing in S2 is ground;
S4, S3 is ground to freeze coffee extract freeze-dried.
The preparation method that the present invention proposes a kind of freeze-dried coffee with baking ground coffee outward appearance, method is simple, easily implements, and the freeze-dried coffee of making has the good appearance that bakes ground coffee, and keeps the good local flavor of freeze-dried coffee.
Detailed description of the invention
Embodiment 1:
One aspect of the present invention, proposes a kind of preparation method with the freeze-dried coffee that toasts ground coffee outward appearance, comprises the following steps:
S1, by the underclad portion slow freezing of the water extract of coffee, supernatant liquid not yet freezes-coffee extract is put into the stainless steel disc of-30 DEG C substantially simultaneously, the liquid layer degree of depth is 19mm, makes extract bottom be frozen into solid, and liquid upper strata or the non-solid state of viscosity.
S2, the top section of coffee extract is sprayed to liquid nitrogen, make its quick freezing;-liquid nitrogen sprays into, and covers the whole surface of extraction liquid layer, and the upper strata adhesive layer of this extract is freezed immediately, then nitrogen natural evaporation.
S3, the coffee extract freezing in S2 is ground;-the tabular coffee extract freezing is crushed to by 8 object sieves, the particle freezing becomes the particle of different colours, and by vibration, these particles evenly divide and deposit on the whole again.
S4, S3 is ground to freeze coffee extract freeze-dried.-then the coffee particles freezing is put into the pressure of 250mmHg (33.33kPa) and the freezer of 42 DEG C carries out freeze-dried.
The present invention proposes a kind of freeze-dried coffee with baking ground coffee outward appearance, method is simple, easily implement, and the peanut black tea drinks taste lubrication of making, delicate fragrance is pleasant.
More than statement is only optimal way of the present invention, it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, within these also should be considered as protection scope of the present invention.
