Description

Technical Field

[0001] This invention relates to the field of baking oven technology, specifically to a baking device and method for white phoenix tea leaves. Background Technology

[0002] Bai Feng Cai tea is a unique vegetable with both medicinal and edible value. Rich in flavonoids, polysaccharides, and various vitamins, it possesses properties such as clearing heat and detoxifying, and promoting blood circulation. In recent years, with the rapid development of the health food market, health teas and ready-to-eat dried vegetable products made from dried and roasted Bai Feng Cai tea have become increasingly popular among consumers. During processing, roasting is a crucial step that determines the product's color, flavor, nutrient retention, and physical properties.

[0003] Currently, traditional methods of drying Bai Feng Cai tea leaves mostly employ hot air circulating ovens or belt dryers for static or continuous drying. These types of equipment generally suffer from the following technical defects: First, the material is in a relatively static state on the trays or conveyor belts, leading to severe leaf accumulation, especially in the later stages when moisture content decreases, easily causing caking. This results in uneven heating between the upper and lower layers, with the bottom layer easily overheating and scorching, while the upper layer remains insufficiently dried, severely affecting the consistency of product quality. Second, the hot air mainly passes through the surface of the material, resulting in poor penetration and difficulty in effectively removing internal moisture, leading to low drying efficiency and high energy consumption.

[0004] Furthermore, in terms of functional enhancement, to improve the antioxidant capacity and color stability of dried white phoenix tea leaves, it is often necessary to spray vitamin C and other auxiliary ingredient solutions during the baking process. However, existing technologies mostly rely on manual spraying, which is inefficient and results in uneven spraying. Therefore, a white phoenix tea leaf baking equipment and method are needed to solve these problems. Summary of the Invention

[0050] The material containing disc 302 is clamped with the hook 3012 through the clamping groove 3023 and hung on the hanging arm 3011, so that when the rocker bed 301 swings, the material containing disc 302 swings through the hanging arm 3011, and the clamping type makes the material containing disc 302 stable during the baking process, and meanwhile, the installation and dismounting of the baking disc are avoided.

[0061] Embodiment 2

[0062] Please refer to Figures 1-11 A white featherleaf tea leaf roasting method, comprising the following steps:

[0063] Step 1, first select fresh white featherleaf tea leaves, remove the roots and yellow leaves, and repeatedly rinse with flowing water for 3-5 times to ensure that the surface mud, insect eggs, and residual agricultural residues are completely removed. After rinsing, the leaves are placed on a perforated bamboo sieve and naturally drained for more than 30 minutes in a well-ventilated place to avoid excessive moisture on the leaf surface affecting the uniformity of subsequent roasting. The drained white featherleaf tea leaves need to be sliced, and a stainless steel knife is used to cut the leaves into 3-4 mm thick slices along the vein direction. The cutting force should be uniform to avoid breaking the leaves. The cut leaves need to be gently shaken to remove residual debris, and then evenly spread in the holding tray 302. The supporting ribs 3021 at the bottom of the holding tray 302 can naturally separate the leaves, keeping a small gap between each leaf, which is beneficial for heat penetration and provides space for subsequent auxiliary material spraying and mechanical lifting. When loading the tray, pay attention to the edge leaves not exceeding the tray body to avoid spilling during swinging.

[0064] Step 2, the pre-processed container 302 needs to be reliably connected with the shaker 301, the shaker 301 is symmetrically installed with a hanging arm 3011 on both sides, the top end of the hanging arm 3011 is provided with a top inverted bevel metal hook 3012, the left and right sides of the container 302 are correspondingly processed with a rectangular clamping groove 3023 matched with the hook 3012, the depth of the clamping groove 3023 is slightly larger than the thickness of the hook 3012, so as to ensure that there is no looseness after embedding, the operator needs to hold the bottom of the container 302 with both hands, slowly press the clamping groove 3023 to the hook 3012, and then test the connection stability by lifting the container 302 slightly, if there is no obvious shaking, it means that the clamping is successful;

[0065] Step 3, the equipment starting stage needs to be operated in steps, first connect the power supply of the heating wire 106, the heating wire 106 starts to heat and reflects through the mirror surface of the cambered surface shaker 301, and uniformly projects the heat radiation to the bottom of the container 302, gradually improves the temperature in the box body 101, at the same time, start the motor 304, the output shaft of the motor 304 drives the rotating disc 303 to rotate at a constant speed, the eccentric shaft 3031 on the side surface of the rotating disc 303 rotates to produce regular displacement, drives the swing rod 3014 to swing left and right, and then drives the shaker 301 to reciprocate, in order to balance the humidity in the box body 101, synchronously open the top exhaust fan 103 at the initial stage of heating, the humid hot air in the box body 101 is exhausted through the top air outlet 102, and at the same time, the dry air outside is sucked into the bottom air inlet 105, forming an air circulation of "in from the bottom and out from the top";

[0066] Step 4, when the temperature in the box body 101 is stabilized at 80-90℃, start the pipeline pump 202 to start auxiliary material spraying, the pipeline pump 202 sucks the vitamin C solution in the auxiliary material box 203 through the internal thread interface 2021, delivers it to the hollow cavity of the spray fin 201 through the pipeline, and finally sprays it out from the atomizing spray hole 2014 on the upper end of the fin 2012, which can uniformly cover the surface of the vegetable slices in the container 302, due to the continuous swinging of the shaker 301, the fin 2012 is intermittently inserted into the rectangular groove 3024 at the bottom of the container 302, which gently lifts the vegetable slices, expands the gap between the leaves, promotes the heat flow, and makes the droplets more easily penetrate into the leaf back, the vitamin C solution rapidly evaporates in the 80-90℃ heat environment, part of the effective components adhere to the surface of the leaves, inhibit the degradation of chlorophyll by using its strong antioxidant property, and delay the browning of the leaves;

[0067] Step 5, after reaching the baking requirements, first turn off the power of the heating wire 106, stop heating, but keep the motor 304 and the exhaust fan 103 continue to run for 5-8 minutes, the motor 304 drives the swing bed 301 to continue to swing, so that the slices are evenly cooled and the remaining water vapor is discharged under the residual heat; the exhaust fan 103 continuously discharges the residual moisture in the box 101, so as to avoid the slices from being soft due to water vapor condensation; when the temperature in the box 101 is reduced to below 50℃, turn off the motor 304 and the exhaust fan 103, carefully take out the material holding tray 302 with a heat insulation glove, and after taking out, the material holding tray 302 needs to be transferred to a cooling rack and placed in a ventilated and cool place to cool to room temperature naturally.

[0068] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
