Description

TECHNICAL FIELD

[0001] The present application relates to the processing technology field of Fritillaria, and in particular to a Fritillaria peeling processing method. BACKGROUND

[0002] Freshly picked Fritillaria needs to be peeled in time, because: first, the outer skin of Fritillaria has strong water retention and contains polyphenols, which are easily oxidized and reddened at room temperature, wrinkled, and moldy, causing rot. After peeling, combined with lime powder or short-term sulfur fumigation, it can quickly dehydrate, inhibit enzyme activity, and extend the shelf life. When Fritillaria is not peeled, its drying speed is slow, about 36-48 hours, and the color of Fritillaria is yellow. Second, when the outer skin is dried, the dense structure of the outer skin hinders water evaporation, and is prone to "dry inside and wet outside" or "bubbling" deformation. After peeling, water can be evenly lost, and the dried pieces are flat, powdery, and white in color. Third, the outer skin of Fritillaria also contains alkaloids (such as fritillaria A and B), bitter amino acids, saponins, and tannins, which, after combining with taste buds, will produce persistent bitterness and astringency.

[0003] Currently, the existing Fritillaria peeling processing technology, such as the disclosed technology with the publication number CN115607618A and the name "Method for processing Zhejiang Fritillaria medicinal materials with oyster shell ash powder", places the graded bulbs into a stainless steel peeling drum with protrusions, and the outer skin is removed by impact and friction until the internal sap of the bulb is exuded. This technology uses a stainless steel peeling drum with protrusions for hard friction, which can remove the outer skin of Fritillaria, but it also easily causes the Fritillaria flesh to wear off. For example, the disclosed technology with the publication number CN105917788A and the name "Method for breaking dormancy of Eichhornia crassipes seeds and improving their survival rate", uses a mixture of seeds and sand for physical peeling, which has a large friction force for physical peeling and also easily causes the Fritillaria flesh to wear off. In addition, after physical peeling with sand, the outer skin of Fritillaria is mixed with sand, which cannot be reused. If the sand containing the outer skin of Fritillaria is reused, the physical peeling ability is weakened, or it is not convenient to control the physical peeling time, i.e. sand with a high content of Fritillaria outer skin (with buffering operation) needs a longer time for physical peeling, and the operation time varies greatly each time.

[0004] Therefore, there is an urgent need for a Fritillaria peeling processing method that is simple to operate, reliable to use, and reusable. SUMMARY

[0005] To solve the above problems, the present application provides a Fritillaria peeling processing method, and the technical solution adopted by the present application is as follows:

[0006] A Fritillaria peeling processing method, comprising the following steps:

[0007] Wash the freshly picked Fritillaria and set aside;

[0008] Put water, fine sand and washed fritillaria in a round barrel with smooth inner wall in the proportion of 3:1:(1.0-2.0), mix evenly, and stir in the same direction for 2-5 minutes; the stirring speed is 120 revolutions per minute; the particle size of the fine sand is 0.125-0.25 mm;

[0009] Filter with a filter screen with a mesh size of 2-5 mm, and rinse to obtain the peeled fritillaria.

[0010] Further, the stirring uses a handheld mixer or a stirring kettle, and the stirring paddle of the handheld mixer or the stirring kettle is inserted into the center of the bottom of the inner wall of the round barrel.

[0011] Further, the filter screen is used to filter the mixture of water, fine sand and the outer skin of fritillaria.

[0012] Put the mixture of water, fine sand and the outer skin of fritillaria in a container, and let the mixture stand for 5-10 minutes.

[0013] The outer skin of fritillaria and the fine sand are layered in the container, the outer skin of fritillaria floats on the water surface, and the fine sand is placed at the bottom of the container.

[0014] Lift out the upper floating outer skin of fritillaria, drain the water in the container, and reuse the fine sand.

[0015] Compared with the prior art, the present application has the following advantages:

[0016] (1) The present application mixes water, fine sand and washed fritillaria, which can ensure the flowability of stirring and physically break the outer skin of washed fritillaria using fine sand, effectively avoiding hard friction damage to the pulp of fritillaria and ensuring the reliability of peeling.

[0017] (2) The present application uses the combination of water and fine sand, according to the density difference between the outer skin of fritillaria and the fine sand, the outer skin of fritillaria floating on the water surface is lifted out after filtration and standing, so as to facilitate the reuse of water and fine sand.

[0018] In summary, the present application has the advantages of simple operation, reliable use, and reuse, and has high practical value and popularization value in the field of fritillaria processing technology. BRIEF DESCRIPTION OF DRAWINGS

[0025] To make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present application include but are not limited to the following embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present application.

[0026] In the embodiments of the present application, the words such as “exemplary” or “for example” are used to mean serving as an example, instance, or illustration. Any embodiment or design solution described as “exemplary” or “for example” in the embodiments of the present application should not be interpreted as being more preferred or advantageous than other embodiments or design solutions. In fact, the use of the words such as “exemplary” or “for example” is intended to present the relevant concept in a specific manner.

[0027] In the description of the embodiments of the present application, the meaning of “plurality” is two or more, unless otherwise specified. For example, a plurality of processing units refers to two or more processing units; a plurality of systems refers to two or more systems.

[0028] As shown in Figures 1 to 5 , the present embodiment provides a Fritillaria peeling processing method, which comprises the following steps:

[0029] Freshly picked Fritillaria is washed and prepared for use. In this process, the washed Fritillaria needs to be selected, or selected before washing, to remove rotten, moldy, worm-eaten, damaged, deformed, and germinated Fritillaria.

[0030] Peeling process: as shown in Figure 2 and Figure 3As shown, the water, fine sand and the cleaned fritillaria bulb are put into a smooth inner wall barrel in a ratio of 3:1:(1.0-2.0), mixed uniformly, and stirred in the same rotation direction for 2-5 minutes. In this embodiment, the stirring speed is 120 revolutions per minute. Here, the fine sand has a particle size range of 0.125-0.25 mm. In this embodiment, the stirring can be performed by a handheld mixer or a stirring tank, and the stirring paddle of the handheld mixer or the stirring tank is inserted into the center of the inner wall bottom of the barrel.

[0031] After the peeling, the mixture is filtered by a filter screen with a mesh size of 2-5 mm, washed by clean water, and the peeled fritillaria bulb is obtained, as shown in Figure 4

[0032] The mixture of the water, fine sand and the fritillaria bulb skin needs to be separated. Since the density of the fine sand is about 1390-1450 kg / m 3 , and the density of the fritillaria bulb skin is about 600-900 kg / m 3 , the density of the water is greater than that of the fritillaria bulb skin and less than that of the fine sand. According to the density difference of the three, the fritillaria bulb skin mixed in the fine sand and water is separated by layering.

[0033] Here, the mixture of the water, fine sand and fritillaria bulb skin is put into a container, stirred, and the mixture is allowed to stand for 5-10 minutes.

[0034] The fritillaria bulb skin and the fine sand are separated by layering in the container, the fritillaria bulb skin floats on the water surface, and the fine sand is placed at the bottom of the container.

[0035] The upper layer of the floating fritillaria bulb skin is fished out, the water in the container is drained, and the fine sand is reused.

[0036] The above embodiments are only preferred embodiments of the present application, and are not a limitation on the protection scope of the present application. Any changes made by using the design principles of the present application and based on non-creative labor shall be within the protection scope of the present application.​
