Problems solved by technology

However, the current freeze-drying method generally has a long drying process, because the product is easy to collapse after freezing or the drying is not complete, resulting in poor freezing effect
Therefore, the prior art has the problems of low freeze-drying efficiency and poor freeze-drying effect.

Embodiment

[0024]A one-step dynamic freeze-drying method of freeze-dried facial mask, such asfigure 1 As shown, including the following steps:

[0025]S1. Pretreatment of the mask carrier: use a dryer to dry the mask carrier; the power of the dryer is 60 kilowatts, and use the dryer to dry the mask carrier for 100 minutes;

[0026]S2. Preparation of facial mask liquid: stir and mix the ingredients of the facial mask liquid evenly to make a facial mask liquid; the raw materials of the facial mask liquid include polysaccharides, ceramides, polymer moisturizing ingredients, collagen and active extracts; in the facial mask liquid, based on The total weight of the facial mask liquid includes: 6 parts of polysaccharides, 1 part of ceramides, 3 parts of high molecular moisturizing ingredients, 10 parts of collagen, and 60 parts of extracts;

[0027]S3. Spraying mask liquid: spray the mask liquid on the mask carrier several times;

[0028]S4. Freeze drying: The freezing tunnel uses liquid nitrogen for freezing an...

Abstract

The invention discloses a one-stage dynamic freeze-drying method of a freeze-dried mask, relates to the technical field of freeze-drying, and aims at solving the problems that the freeze-drying treatment efficiency is low and the freeze-drying treatment effect is poor. The technical key point is that the one-stage dynamic freeze-drying method of the freeze-dried mask comprises the following steps:preparation of a mask liquid; mask liquid spraying; freeze drying; and package. A proper cooling and freeze-drying procedure is set for a mask carrier, so that the temperature of the mask carrier isdynamically changed in the freezing tunnel, active matters of the mask are reserved in a most proper manner under the condition that the concentration and the vacuum degree of a material system are not changed, and the advantages of higher freeze-drying treatment efficiency and better freeze-drying treatment effect are achieved.

Description

Technical field[0001]The invention relates to the technical field of freeze-drying, in particular to a one-step dynamic freeze-drying method for freeze-dried facial masks.Background technique[0002]Freeze-drying is to freeze a substance containing a large amount of water into a solid by cooling in advance, and then sublimate the solid water directly, while the substance itself remains in the ice shelf when it is frozen. Freeze-dried products are dried at a temperature below 0°C for most of the time, that is, when the product is frozen, until the later stage, in order to further reduce the residual moisture content of the product, the product is allowed to rise to a temperature above 0°C. In the process of freeze-drying at low temperature, the loss of some volatile components in the substance is very small. It is suitable for drying some chemical products, medicines and food, and the dried product can be stored for a long time without deterioration.[0003]At present, the existing freez...
