Description

Technical Field

[0001] This invention relates to the technical field of jujube seed roasting equipment, and specifically discloses a jujube seed roasting device. Background Technology

[0002] Sour jujube seed is an important raw material in the traditional Chinese medicine and health food industry. After being roasted, sour jujube seed can effectively mitigate its medicinal properties, enhance its aroma, and optimize its taste. The temperature control, uniformity of material turning, and adhesion of seasonings during roasting directly determine the quality, medicinal stability, and appearance of the finished sour jujube seed product. Refined and standardized roasting is the core and key process in the deep processing of sour jujube seed, and it is also an important prerequisite for ensuring the consistent quality of sour jujube seed products in the market.

[0003] The jujube seed roasting device is a specialized production equipment for the batch roasting and processing of jujube seeds. It mainly completes the integrated processing steps of roasting jujube seeds, turning materials, and attaching auxiliary ingredients and seasonings. It is widely used in Chinese herbal medicine deep processing plants, health food production workshops, and agricultural and sideline product fine processing production lines. It can realize the industrialized and standardized roasting of jujube seeds and is an indispensable core processing equipment for the large-scale and refined production of jujube seed deep processing industry.

[0004] In the large-scale continuous roasting and processing of jujube seeds, the temperature control and regulation capabilities of the equipment, the adaptability of the power linkage between various mechanisms, and the coordinated performance of material turning and seasoning feeding directly affect the uniformity of heating, the effect of seasoning coating, and the yield of finished products. These factors determine the overall processing quality and energy consumption of the production line. Currently, traditional roasting equipment used for jujube seed processing faces critical problems that urgently need to be addressed in actual industrial mass production. Existing jujube seed roasting equipment mostly adopts a fixed, continuous heating structure, with the heating plate and roasting cylinder in constant contact for heating. This makes intermittent temperature control impossible, and continuous heating easily leads to excessively high internal temperatures and rapid temperature rise in the roasting cylinder, causing localized scorching and uneven heating of the jujube seeds, severely affecting the taste and quality of the finished product. Poor temperature control accuracy makes it difficult to guarantee a high yield. Furthermore, the independent functional structures of traditional equipment result in low power utilization, requiring individual drive mechanisms for each component, leading to complex equipment structures and high energy consumption. In addition, traditional jujube seed roasting equipment... The traditional equipment's turning, feeding, and seasoning processes are disconnected and cannot achieve power linkage. Conventional equipment often adds seasonings only once or sprays them at fixed points, lacking a structure that feeds them synchronously with the turning process. This makes it difficult for the seasonings to adhere evenly to the surface of the jujube kernels, easily resulting in some areas being over-seasoned while others are unseasoned, leading to poor coating and inconsistent product quality. At the same time, traditional equipment lacks a linkage air-blowing feeding structure, making it impossible to automatically and quantitatively deliver seasonings based on the turning power. It mostly relies on manual feeding, which not only increases labor costs but also makes it difficult to accurately control the timing and amount of feeding, greatly affecting the stir-frying and seasoning effect and processing efficiency. The overall equipment suffers from many problems such as poor temperature control, uneven material turning, poor seasoning adhesion, wasted power resources, and low automation, making it difficult to achieve high-quality stir-frying processing of jujube kernels with uniform heating and coating, and failing to meet the needs of refined, high-quality, large-scale production. Therefore, a jujube kernel stir-frying device was invented to address these shortcomings. Summary of the Invention

[0005] To address the technical problem of excessively high frying temperature of jujube seeds due to continuous heating, resulting in surface scorching, the present invention adopts the following technical solution: a jujube seed frying device, comprising a frying cylinder on which a fixing frame is fixedly installed.

[0006] The heating plate, located below the frying pan, generates heat.

[0007] The lifting assembly, mounted on a fixed frame and connected to the heating plate, can drive the heating plate to move up and down.

[0008] The turning component is connected to the inside of the frying cylinder.

[0009] The first and second storage boxes are both fixedly installed on the frame and located above the frying cylinder, and are respectively connected to the inside of the frying cylinder through the conveying assembly.

[0010] The air-blowing component, mounted on a fixed frame and connected to the inside of the second storage box, is capable of feeding the seasonings from the second storage box into the frying drum.

[0011] Furthermore, the lifting assembly includes a lifting plate that is slidably mounted on a fixed frame, a heating plate that is fixedly mounted on the side of the lifting plate facing the frying cylinder, the side of the heating plate facing the frying cylinder being arc-shaped, the radius of the arc-shaped side of the heating plate being equal to the radius of the outer surface of the frying cylinder, and the side of the lifting plate away from the heating plate being flat.

[0012] Furthermore, a first motor is fixedly installed on the fixed frame, a first drive shaft is fixedly installed at the output end of the first motor, a second drive shaft is rotatably installed on the fixed frame, a first drive chain is connected to the second drive shaft, the second drive shaft and the first drive shaft form a chain drive through the first drive chain, and multiple cams are fixedly installed on the outer surface of the second drive shaft, the cams and the plane of the lifting plate form a cam push rod drive.

[0013] Furthermore, when the cam pushes the lifting plate to its highest position, the heating plate comes into contact with the outer surface of the frying cylinder.

[0014] Furthermore, a first fixed frame and a second fixed frame are also fixedly installed on the fixed frame.

A second turntable is rotatably connected to the end of the first connecting rod away from the first turntable. The second turntable is fixedly installed on the outer surface of the third drive shaft.

[0015] Furthermore, the distance between the connection point of the first link and the second turntable and the axis of the second turntable is greater than the distance between the connection point of the first link and the first turntable and the axis of the first turntable.

[0016] Furthermore, a mounting frame is fixedly installed on the first fixed frame, and both the first storage box and the second storage box are fixedly installed on the mounting frame.

A piston rod is slidably installed on the inner wall of the air cylinder, and the piston rod is rotatably connected to the end of the second connecting rod away from the second turntable.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: (1) The present invention controls the heating plate to make intermittent contact with the outer surface of the frying cylinder through the lifting component, thereby avoiding the excessively high temperature of the jujube kernels during continuous heating. At the same time, the lifting component provides a power source for the turning component to turn the jujube kernels, thereby ensuring that the jujube kernels are roasted evenly.

[0020] (2) The present invention utilizes the operation of the flipping component to provide power to the air blowing component, thereby sending the seasoning in the second storage box into the frying cylinder. In this way, the seasoning is evenly wrapped on the outer surface of the jujube kernel by the flipping component, and the seasoning is adhered to the outer surface of the jujube kernel by roasting.

[0041] Appendix Figure 5 To the attached Figure 10 and attached Figure 12As shown, in a preferred embodiment, an air-blowing box 401 is fixedly installed between the two sets of first support columns 102. An air-blowing assembly is connected to the air-blowing box 401. The air-blowing assembly includes a delivery pipe 406 connected to the air-blowing box 401. A one-way valve is installed at the connection between the air-blowing box 401 and the delivery pipe 406. The one-way valve ensures that gas can only enter the delivery pipe 406 from the air-blowing box 401, and gas cannot enter the air-blowing box 401 from the delivery pipe 406. The air-blowing box 401 and the delivery pipe 406 are connected by a second storage box 213. An air-blowing cylinder 402 is fixedly installed on the air-blowing box 401. The air-blowing cylinder 402 communicates with the interior of the air-blowing box 401. The inner wall of the air-blowing cylinder 402...

By sliding the piston along the inner wall of the air cylinder 402, the gas in the air chamber 401 can be blown into the second storage box 213 through the delivery pipe 406, thereby sending the diluted honey or brine in the second storage box 213 into the roasting cylinder 107.

[0042] The working principle of this invention is as follows: (a) Before starting work, according to the type of jujube seeds to be roasted, the diluted honey or salt water is fed into the roasting cylinder 107. When roasting salt-roasted jujube seeds, salt water is fed into the roasting cylinder 107, and when roasting honey-roasted jujube seeds, diluted honey is fed into the roasting cylinder 107. When starting work, the heating power supply is turned on, and the heating plate 218 generates heat through the heating resistance wire, thereby heating the inside of the roasting cylinder 107. After heating for 10 minutes, the first motor 105 and the second motor 214 are started at the same time. The first transmission chain 206 drives the second transmission shaft 203 to rotate, which in turn drives the cam 204 to rotate. The rotation of the cam 204 achieves intermittent contact between the heating plate 218 and the outer surface of the roasting cylinder 107, thereby avoiding the jujube seeds from being roasted too high due to continuous heating and scorching of the outer surface of the jujube seeds.

[0043] (ii) When solenoid valve one and solenoid valve two are activated, the jujube kernels in the first storage box 212 enter the roasting cylinder 107 through the first feeding pipe 216. At the same time, the second drive shaft 203 drives the first turntable 305 to rotate through the second drive chain 303, and then drives the second turntable 309 to swing back and forth through the first connecting rod 308. The second turntable 309 drives the piston rod 403 to slide back and forth along the inner wall of the air blower 402 through the second connecting rod 405, so as to blow the gas in the air blower box 401 into the second storage box 213 through the conveying pipe 406, thereby sending the diluted honey or brine in the second storage box 213 into the roasting cylinder 107.

[0044] (iii) The second turntable 309 swings back and forth, driving the stirring rod 302 to move back and forth through the third drive shaft 301. Thus, the stirring rod 302 evenly coats the seasoning on the outer surface of the jujube kernel, thereby achieving the effect of adhering the seasoning to the outer surface of the jujube kernel through roasting.

[0045] (iv) After the frying is finished, remove the second end cap 109 from the frying cylinder 107, then turn off the heating power, and after cooling for 15 minutes, take the fried jujube kernels out of the frying cylinder 107 from the connection between the second end cap 109 and the frying cylinder 107.
