[0017] Further, the drying and molding device includes a machine platform, a lifting support frame fixedly arranged on the machine platform, a drying reactor arranged on the lifting support frame, a drying molding chamber arranged in the drying reactor, and an auxiliary molding device arranged in the drying molding chamber. The drying reactor includes an upper kettle body and a lower kettle body that cooperate with each other. The lower kettle body is fixedly arranged at the bottom of the lifting support frame. The upper kettle body is movably arranged on the lifting support frame and moves up and down along the height direction of the lifting support frame, approaching or moving away from the lower kettle body. The drying and molding chamber includes a first molding chamber arranged on the upper kettle body and a second molding chamber arranged on the lower kettle body. The first molding chamber is arranged on a side of the upper kettle body close to the lower kettle body, and the second molding chamber is arranged on a side of the lower kettle body close to the upper kettle body. The auxiliary molding device includes a first molding mechanism and a second molding mechanism that are symmetrical to each other. The first molding mechanism is arranged in the first molding chamber, and the second molding mechanism is arranged in the second molding chamber. The first molding mechanism and the second molding mechanism work together to avoid adhesion of the solid-liquid mixture to the equipment during the drying and molding process.

[0018] Furthermore, the first molding mechanism includes a plurality of first molding plates arranged in the first molding cavity and a first ejection device arranged in the upper kettle body; the second molding mechanism includes a plurality of second molding plates arranged in the second molding cavity and a second ejection device arranged in the lower kettle body; the first molding plates and the second molding plates are arranged in a matrix; the first ejection device is used to eject the first molding plates outward; the second ejection device is used to eject the second molding plates outward; and the first molding plates and the second molding plates are both metal plates.

[0019] Further, the first ejection device includes a first rotating rod, a first main ejection block and a first auxiliary ejection block fixedly arranged on the first rotating rod, the first main ejection block and the first auxiliary ejection block are arranged in opposite directions, the first rotating rod is driven to rotate by a first rotating motor, and the first main ejection block and the first auxiliary ejection block rotate following the first rotating rod; the second ejection device includes a second rotating rod, a second main ejection block and a second auxiliary ejection block fixedly arranged on the second rotating rod, the second main ejection block and the second auxiliary ejection block are arranged in opposite directions, the second rotating rod is driven to rotate by a second rotating motor, and the second main ejection block and the second auxiliary ejection block rotate following the second rotating rod.

[0021] Furthermore, the height of the first main pushing block is higher than that of the first auxiliary pushing block, the height of the second main pushing block is higher than that of the second auxiliary pushing block, and magnets are provided at the free ends of the first auxiliary pushing block and the second auxiliary pushing block.

[0022] By adopting the above technical solution, the beneficial effects of the present invention are:

[0023] 1. Compared with the existing traditional donkey-hide gelatin and longan mixture products, the advantages of the present invention are that the longan in the finished product is dried longan rather than fresh longan, and the dried longan has a stronger thermal property than the fresh longan, and has been preliminarily concentrated during the drying process, and the beneficial components have been preliminarily extracted; at the same time, jujube, mulberry, wolfberry, sea buckthorn, licorice, ginger slices and other ingredients are added to the mixture, and these ingredients are all hot warming ingredients. The combination of these ingredients can make the finished product more suitable for women's physical conditioning during confinement or during the physiological period, and brown sugar is added to adjust the taste. Brown sugar can replenish qi and blood while adjusting the taste. At the same time, the mixture of the present invention is also very rich in eating scenarios, and can be chewed directly or brewed with hot water and drunk.

[0024] 2. In the preparation method of the donkey-hide gelatin and longan composition of the present invention, donkey-hide gelatin and brown sugar are not included in the preliminary raw material mixing process. The reason for excluding donkey-hide gelatin and brown sugar is that the raw materials will be constantly in contact and friction with the stirring roller during the stirring process, and the friction will generate heat. If brown sugar and donkey-hide gelatin are also included, it may cause the brown sugar and donkey-hide gelatin to melt due to the heat, which will cause the melted brown sugar and donkey-hide gelatin to adhere to other raw materials, and then local agglomeration will occur, or the raw materials will adhere to the inner wall of the stirring equipment or the stirring roller, resulting in reduced mixing efficiency.

[0025] 3. In the preparation method of the donkey-hide gelatin and longan composition of the present invention, donkey-hide gelatin and brown sugar are not included in the crushing process. The principle is roughly similar to stirring and mixing. The crushing blade in the crushing process runs faster than the stirring roller, and more heat is generated, so it is easier to melt the donkey-hide gelatin and brown sugar. After the brown sugar and donkey-hide gelatin melt, they may adhere to the blade of the crushing blade, making the originally sharp blade blunt and reducing the crushing efficiency. At the same time, in the preparation method of the donkey-hide gelatin and longan composition of the present invention, the reason why brown sugar and donkey-hide gelatin are not involved in the stirring and crushing step is that both are soluble in water and do not need to be stirred and crushed.

[0026] 4. In the present invention, the raw materials are stirred and mixed and then crushed, and then brown sugar, donkey-hide gelatin and distilled water are added for boiling. During the boiling process, the effective ingredients in the raw materials can be completely released, and with continuous boiling, the brown sugar, donkey-hide gelatin, distilled water and other raw materials are slowly mixed to form a thick solid-liquid mixture. With the continuous evaporation of water, the water content in the solid-liquid mixture is continuously reduced, and the solid-liquid mixture will slowly change into a solid form. When it is heated and concentrated to a state where the liquid concentrate only serves as a binder for the solid raw materials, it can be extruded and formed, and the effective ingredients of the finished product obtained after extrusion molding are completely retained.

[0027] 5. Since the accompanying process after boiling and concentrating in the development method of the present invention is extrusion molding, and packaging and storage are carried out after molding, a drying and molding device is specially proposed for the extrusion molding process, which can ensure that the solid-liquid mixture will not adhere to the equipment during the extrusion molding of the solid-liquid mixture by the drying and molding device, and the drying and concentration process in step S5 adopts intermittent drying and concentration. After the equipment works for 1-3 minutes, it is powered off and cooled for 1-3 minutes. Because it is different from conventional drying equipment, the liquid in the present invention is a viscous liquid, and high temperature can evaporate and dry it, but it is not conducive to its solidification, while low temperature can make it solidify, so a high and low temperature switching mode is adopted for drying, concentration and extrusion molding.

[0028] 6. The special equipment proposed in the present invention, the drying and molding device, has an advantage over the existing drying and molding equipment in that it is more suitable for drying viscous solid-liquid mixtures, ensuring that the solid-liquid mixture will not adhere to the equipment during the drying and molding process. The principle is that a first molding mechanism and a second molding mechanism are respectively provided, and the first molding mechanism and the second molding mechanism work together to keep the solid-liquid mixture in a separated state from the first molding mechanism and the second molding mechanism during the drying process, and this state accompanies the entire drying process, which can ensure that the surface of the solid-liquid mixture remains intact after it is completely dried, and will not adhere to the equipment.

[0029] 7. The principle of the first molding mechanism and the second molding mechanism in the present invention during operation is that the first molding plate and the second molding plate serve as upper and lower contact surfaces with the solid-liquid mixture, wherein the first molding plate is attached to or separated from the solid-liquid mixture under the pushing action of the first main pushing block and the first auxiliary pushing block, but not all the first molding plates are separated, but part of the first molding plates are still in contact with the solid-liquid mixture, and part of the first molding plates are separated from the solid-liquid mixture, and the contact and separation are controlled by the first main pushing block and the first auxiliary pushing block on the first rotating rod. When the first main pushing block contacts the first molding plate , providing support for the first forming plate, and with the rotation of the first rotating rod, the first auxiliary pushing block slowly changes to approach the first forming plate, and because the height of the first auxiliary pushing block is lower than that of the first main pushing block, and a magnet is arranged at the free end of the first auxiliary pushing block, when the first auxiliary pushing block approaches the first forming plate, it will be attracted to it under the action of magnetic attraction, and the first forming plate will be separated from the solid-liquid mixture at this time, and this process will be continuously cycled with the rotation of the first rotating rod, ensuring that each first forming plate has a contact and separation process with the solid-liquid mixture, and the working principle of the second forming plate is the same as that of the first forming plate.
