Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chrysanthemum tea preparation, in particular to a drying process of Jinshihuangchrysanthemum. BACKGROUND

[0002] Jinshihuangchrysanthemum is a kind of chrysanthemum, with bright yellow color, rich in amino acids, vitamins and trace elements and other substances beneficial to human body, and most of these substances in petals can penetrate into water, so Jinshihuangchrysanthemum can be made into Jinshihuangchrysanthemum tea for drinking. In the preparation process of Jinshihuangchrysanthemum tea, Jinshihuangchrysanthemum needs to be dried, drying is to store for a long time without destroying its nutrients, and the water in Jinshihuangchrysanthemum is removed by drying method to increase the concentration of soluble substances to a level that is difficult for microorganisms to utilize. In the drying process of Jinshihuangchrysanthemum, the drying process determines the quality of Jinshihuangchrysanthemum.

[0003] Through retrieval, the patent with application number CN201710299634.5 proposes a preparation method of Jinshihuangchrysanthemum tea, in which the drying process of Jinshihuangchrysanthemum is as follows: the bamboo sieve full of Jinshihuangchrysanthemum is placed on the steel frame in layers for 4-5h to obtain semi-dry chrysanthemum; temperature control drying: the obtained semi-dry chrysanthemum is pushed into the drying room together with the steel frame to carry out segmented temperature control drying to obtain dry chrysanthemum, and the segmented temperature control drying is divided into five segments, and the temperature and time of the five segments are as follows: 36℃ for 12h, 41℃ for 10h, 46℃ for 12h, 51℃ for 20h, and 56℃ for 18-19h.

[0004] Since the above scheme needs to be first dried for 4-5h to obtain semi-dry chrysanthemum when used, the drying temperature and humidity cannot be accurately controlled during the drying, which will affect the drying effect of chrysanthemum; and the temperature change interval of petals during drying is long, for example, the petals are shaped at 46℃ all the time, and the water in the flesh and the water in the gum of petals, petal and receptacle are discharged together, and the water discharged from the gum will affect the flesh of petals, affect the shaping effect of petals, and further affect the shape of dry flowers and the quality of finished dry flowers. Based on this, the present application proposes a drying process of Jinshihuangchrysanthemum. SUMMARY

[0005] The present application provides a drying process of Jinshihuangchrysanthemum, which solves the problems that the drying temperature and humidity cannot be accurately controlled during the drying, and the dryness of semi-dry chrysanthemum cannot be accurately controlled; and the temperature change interval is long during the drying process, which will affect the shape and color of finished dry flowers.

[0006] The present invention provides the following technical solutions: a drying process for golden chrysanthemum, which omits the spreading and airing step and directly dries the fresh golden chrysanthemum; the drying process of the golden chrysanthemum is divided into eight stages: a drying and soft soft stage, an initial softening stage, a middle softening stage, a softening and consolidating stage, a shaping and coloring stage, a shaping and coloring stabilization stage, a drying adaptation stage and a drying stage, and the drying time, temperature and humidity of each stage are strictly controlled to make the petals of the finished product naturally bright in color.

[0007] The present application provides a drying process for golden chrysanthemum, comprising the following steps:

[0008] Step 1: Material selection

[0009] Select flowers that are more than 70% open, with buds or core bags in the flower core, and the flower core is peach-shaped, spiral ball-shaped, or claw-shaped, about the size of a finger cap;

[0010] Step 2: Arrange the ingredients

[0011] The placement requirements for single chrysanthemums with petals less than five rings are as follows: flowers with a diameter of less than 80mm should be placed in three layers in the sieve tray, and flowers with a diameter of 80mm-100mm should be placed in two and a half layers in the sieve tray; flowers with a diameter of about 100mm, and petals with more than five rings should be placed in one and a half to two layers; flowers with a diameter of about 120mm, and petals with more than five rings should be placed in one layer; flowers of 130mm and above are recommended to be placed in one layer; the arranged sieve tray is placed in the drying equipment with an air energy heating system;

[0012] Step 3: Dry and soft period

[0013] Dehumidification and drying are carried out simultaneously, maintaining the temperature at a medium-low temperature of 35°C for 15-20 hours to remove the surface moisture and superficial moisture of the petals and cores. The surface of the petals and cores are free of moisture and softened, and the cores are also softened. The dehumidification fan is turned on for 3 minutes and then rested for 1-3 minutes;

[0014] Step 4: Initial Softening

[0015] Dehumidification and drying are carried out simultaneously, maintaining the temperature at 38°C for 15-20 hours to remove moisture from the fleshy part of the petals and the core of the flowers, so that the gelatinous part of the petals will soften in the absence of water, and the petals and the core of the flowers will soften completely. The dehumidification fan will be turned on for 3 minutes and then rest for 1-5 minutes;

[0016] Step 5: Mid-bake

[0017] Dehumidification and drying are carried out simultaneously, with the dehumidification fan working continuously to maintain the temperature at 41°C and drying for 10-15 hours to make the petals soft and relaxed, without the hard feeling of raw flowers;

[0018] Step 6: Baking and consolidation period

[0019] Dehumidification and drying are carried out simultaneously, and the dehumidification fan is continuously working to maintain the temperature at a medium temperature of 43°C. The drying time is 4-12 hours to soften the dead corners that have not been softened in step 5.

[0020] Step 7: Shaping and coloring period

[0021] Dehumidification and drying are carried out simultaneously, and the dehumidification fan is working continuously, mainly for drying and weak dehumidification. The temperature is maintained at a medium-high temperature of 45°C. Dry for 2-5 hours. Observe with the naked eye that the flower core and petals are soft or the flower core is slightly dry or slightly hard, and the color is bright.

[0022] Step 8: Styling and color stabilization period

[0023] Dehumidification and drying are carried out simultaneously, and the dehumidification is continuous and weak. The temperature is maintained at a medium-high temperature of 47°C and the drying time is 2-4 hours. This is to continue the shaping of the chrysanthemums that have not been fully shaped in the previous stage. The high temperature is used to force the moisture in the gelatin in the flesh of the flower core, petals and receptacle to be discharged and shaped.

[0024] Step 9: Drying adaptation period

[0025] Maintain the temperature at a high temperature of 51°C for 1-2 hours to drain the deep moisture in the gelatin of the petals, flower core and receptacle, so as to prepare for the high temperature drying period. During the drying process, the strong aroma of the dried chrysanthemum flowers is released.

[0026] Step 10: Drying period

[0027] Maintain the temperature at a high temperature of 58℃-70℃ for more than 5 hours, until the petals and flower cores are dry and hard, and are brittle to the touch. During the drying process, proper moisture removal is carried out to maintain the drying humidity at around 16%.

[0028] Furthermore, in step four, the intermittent stop time of the dehumidification fan is related to the outside temperature. The higher the outside temperature, the shorter the stop time of the dehumidification fan. When the outside temperature is higher than 20°C, the stop time is 1 minute. When the outside temperature is lower than 10°C, the stop time of the dehumidification fan is 3-5 minutes.

[0029] Furthermore, the petals processed in step five are so soft that they appear to have darker color when observed with the naked eye, and have a somewhat crystal-clear feel. The petals are soft and loose, and feel like cotton when touched with fingers. When the flower core is touched, it collapses and does not rebound with a slight touch or pressure of the fingers. The flower core feels damp and sticky. When picked up, the petals feel as soft as boneless, without the hard feeling of raw flowers.

[0030] Furthermore, in step 6, if the petals are glittering and translucent, with rotten edges and soft petals drooping, that is, they are over-softened, the temperature must be immediately raised to 47°C, dried for 2 hours, then raised to 51°C and dried for 2 hours, and then directly dried at high temperature.

[0031] Further, the judgment standard of the step eight is that the most of the surface layer of the chrysanthemum is dry, and the feeling of soft and hard is felt, the color is very natural and bright, if the feeling of the core and the petal of the surface layer of the chrysanthemum is slightly hard, the smell of the slightly fresh chrysanthemum and the strong dry chrysanthemum is smelled, and the core and the petal of more than 75% of the surface layer of the chrysanthemum are slightly hard, the next stage can be entered.

[0032] Further, the judgment basis of the flower type in the step nine is that the flower type is natural and slightly inner rolled, the petal is in the dry and flat fluffy state of natural loss of water, the core is also in the natural inner rolled fluffy state, the receptacle is slightly hard or slightly hard, the color is natural dry cyan, the whole chrysanthemum petal is hard and straight without drooping.

[0033] Further, in the step ten, when the external environment temperature is below 15℃, the dehumidification fan is set to work for 1 minute every 30-60 minutes; when the external environment temperature is above 20-28℃, the dehumidification fan is set to work for 1 minute every 20 minutes; when the external environment is 28-35℃, the dehumidification fan is set to work for 1 minute every 10 minutes; when the external environment is above 35℃, the dehumidification fan is set to work for 1 minute every 3 minutes.

[0034] Compared with the prior art, the present application has the following beneficial effects:

[0035] 1. The gold silk imperial chrysanthemum drying process directly dries the fresh gold silk imperial chrysanthemum placed in order, can accurately control the dryness of the gold silk imperial chrysanthemum, and further makes the product quality consistent, so that the quality of the dried gold silk imperial chrysanthemum is stable; the drying process of the gold silk imperial chrysanthemum is divided into eight stages: softening period, softening initial period, softening middle period, softening consolidation period, shaping and color fixing period, shaping and color fixing stable period, drying adaptation period and drying period, and the drying time, temperature and humidity of each stage are strictly controlled, so that the color of the finished product petal is natural and bright.

[0036] 2. The gold silk imperial chrysanthemum drying process can improve the tolerance of the core through the setting of the temperature in the softening middle period and the softening consolidation period, so that the core will not appear black heart.

[0037] 3. The gold silk imperial chrysanthemum drying process sets the temperature in the shaping and color fixing period, so that the water in the petal is evaporated and lost quickly, and the water in the gum in the receptacle, core and petal is evaporated and fixed in time, the temperature in the shaping and color fixing stable period is set, the water in the gum in the receptacle, core and petal is forced to be discharged and shaped by high temperature, and the two kinds of temperature are used in combination, so that the gold silk imperial chrysanthemum is quickly shaped, and the color is natural and bright.

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0048] The present application provides a gold thread imperial chrysanthemum drying process, comprising the following steps:

[0049] Step one, material selection

[0050] The flower opening reaches more than 70%, the flower core part has flower buds or core package, the flower core is peach type, spiral ball package type, inner claw ball package type, and the size is about the size of a finger cover. This kind of flower is relatively tender, and is not resistant to temperature, so the drying process requirement is very high, and the dried flower product will also be very good.

[0051] Step two, material arrangement

[0052] The single chrysanthemum wrapped petal has five rings or less, and the placement requirement is: the flowers with a diameter less than 80 mm are placed in three layers in the sieve tray, the flowers with a diameter of 80 mm-100 mm are placed in two and a half layers in the sieve tray; the flowers with a diameter of about 100 mm, the single chrysanthemum wrapped petal has five rings or more, are placed in one and a half to 2 layers; the flowers with a diameter of about 120 mm, the single chrysanthemum wrapped petal has five rings or more, are placed in 1 layer; the flowers with a diameter of 130 mm or more are recommended to be placed in 1 layer, and when placing, the core is upwards. The placed sieve tray is placed in the drying equipment with air energy heating system.

[0053] Step three, the neatly placed gold silk emperor chrysanthemum is directly dried, and the gold silk emperor chrysanthemum drying step is divided into eight stages: softening period, softening period, softening medium period, softening consolidation period, shaping and color fixing period, shaping and color fixing stabilization period, drying adaptation period and drying period, and the settings of each stage are as follows:

[0054] The first stage, dry softening period: in this stage, the temperature is maintained at medium-low temperature 35℃, to remove the surface moisture and superficial moisture of the petal and core, the petal and core are soft, like being sunned, and it takes about 15-20 hours to enter the next stage. In this stage, dehumidification and drying need to be carried out synchronously, and the dehumidification fan starts for 3 minutes and stops for 1-3 minutes.

[0055] The second stage, softening initial stage (commonly known as softening initial stage): in this stage, the temperature is maintained at 38℃, and the drying time is 15-20h. In this stage, dehumidification and drying need to be carried out synchronously, and the dehumidification fan starts for 3 minutes and stops for 1-5 minutes (the dehumidification fan stopping time is related to the external temperature. The higher the external temperature, the shorter the dehumidification fan stopping time. If the external temperature is more than 20 degrees, the stopping time is about 1 minute. If the external temperature is below 10 degrees, the dehumidification fan stopping time is longer, about 3-5 minutes, to accumulate heat in the drying room);

[0056] The purpose of this stage is to remove part of the flesh moisture of the petal and core, to make the gelatinous part of the flesh of the petal soft in water shortage, and to make the petal and core completely soft, like being sunned for an afternoon in summer at 38° high temperature, and the core is very soft when touched by fingers, without the hardness of fresh flowers. It is required to reach the feeling of touching cotton flowers, and the petal is soft when pressing the core.

[0057] Third stage, the middle of the softening (commonly known as the flat period): in this stage, the temperature is maintained at 41 °C, dried for 10-15 h, and dried simultaneously, the petals are soft to the naked eye, the color is deep, and there is a sense of crystal clear, the petals are soft and relaxed, the feeling of touching the cotton on the fingers, when touching the core with fingers, the petals collapse with slight touch and light pressure and do not rebound, the feeling of the core is wet and sticky, when holding, the petals are soft like boneless, without the hard feeling of the flower, the next stage of drying can be carried out;

[0058] Fourth stage, full softening period (commonly known as the late flat period, all flat): drying and dehumidifying are carried out simultaneously, the temperature is maintained at medium temperature 43 °C, and the drying time is determined by the amount of flowers to soften the dead angle in the third stage.

[0059] The full softening period can determine that the core tolerance will not produce black heart under the condition of high temperature in the later period. If the full softening is not in place, black heart may occur when the temperature is raised to 45 degrees.

[0060] Fifth stage, shaping and color fixing period: drying and dehumidifying are carried out simultaneously, with weak dehumidification as the main drying, the temperature is maintained at medium-high temperature 45 °C, and the drying time is 2-5 hours, the core and petals are soft or the core is slightly dry or slightly hard, the color is bright, the gelatin in the petal, core and petal is not affected by the water in the gelatin and is evaporated to dry and shape, the fast shaping speed can make the petals involute or upwarp, the flower shape is like a rose shape, the flower shape is very beautiful, and after slight shaping, it can enter the next stage of temperature rising for further shaping.

[0061] Sixth stage, shaping and color fixing and stabilizing period: drying and dehumidifying are carried out simultaneously, and the dehumidification is continuous and weak, the temperature is maintained at medium-high temperature 47 °C, and the drying time is 2-4 h, which is the continuous shaping work of the chrysanthemum in the previous stage, the gelatin in the petal, core and petal is forced to be shaped by high temperature, the judgment standard is that most of the surface chrysanthemum is dry, with soft and hard feeling, the color is very natural and bright, if the touch of the surface chrysanthemum has a slightly hard feeling, there will be a slight smell of fresh flowers and strong dry flowers, and when the surface chrysanthemum has a slightly hard feeling, it can enter the next stage.

[0062] Seventh stage, drying adaptation period: the temperature is maintained at high temperature 51 °C, and the drying time is 1-2 h, the deep water in the gelatin in the petal, core and petal is discharged, and the basis for entering the high temperature drying period is prepared, and the dry chrysanthemum smell is scattered outside during drying, the shape is natural and slightly involute, the petals are dry and flat, the core is also natural and involute, the receptacle is slightly hard or slightly hard, the color is natural and dry green, the whole chrysanthemum is hard and straight without drooping.

[0063] The eighth stage, drying period: maintain the temperature at high temperature 58-70℃, drying time is more than 5 hours, until the petals and the core are dry and hard, easy to break when touched, and appropriately remove the moisture during drying, so that the drying humidity is maintained at about 16%, when the external environment temperature is below 15℃, set the exhaust fan to 30-60 minutes for 1 minute; when the external environment temperature is more than 20-28℃, set the exhaust fan to 20 minutes for 1 minute; when the external environment is 28-35℃, set the exhaust fan to 10 minutes for 1 minute; when the external environment is more than 35℃, set the exhaust fan to 3 minutes for 1 minute.

[0064] In the drying and softening period and the softening consolidation period of the golden silk chrysanthemum, it is important to avoid over-softening. If the petals appear to be crystal clear, with rotten edges and soft petals, it means that the softening is over. In this case, the temperature should be immediately increased to 47℃, and dried for 2 hours, then increased to 51℃ and dried for 2 hours, and then directly dried at high temperature. Because the soft and flat part of the gel in the petals cannot remove the water at a temperature of 43℃, the gel cannot dry. If the temperature is not increased in time, the gel in the petals will soften and fall, which is similar to the feeling of crystal clear and rotten petals. Some of the cores will be independent, and the petals will be flat and soft. If the petals are not increased in time, the petals will soften and rot, and the color will become darker. If the petals appear to be crystal clear and rotten at the tip of the petals during the period of 43℃, the temperature must be increased immediately. If the temperature is not increased or increased for a long time, the petals will be slow-dried, and even if they are dried, the color will become darker, and in severe cases, the petals will become yellow or red, and the petals will become thin or the tip of the petals will appear black. Therefore, the drying and softening period of the chrysanthemum is very important, and the time control is very strict. If the time is controlled well, the petals will not be soft, the core and the petals will not be separated, and the temperature will be increased to 45℃ in time. The petals will be dried for 4 hours, then increased to 47℃ and dried for 3 hours, and then increased to 51℃ and dried for 2 hours. In this way, the water in the gel in the petals and the core will be quickly removed, the petals will be quickly shaped and hardened, and the quality of the dried flowers will be good.

[0065] An embodiment of the present application:

[0066] 1. Select the golden silk chrysanthemum with more than 70% of the flowers opened, and the core part with buds or core packages;
