Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to drying equipment and a drying process for oil-tea camellia seeds. Background Art

[0002] Camellia seeds, as the fruit of the oil-tea tree, are mainly used to produce camellia oil. They have high nutritional value and economic benefits and are widely used in food, cosmetics, and pharmaceuticals. In order to ensure the quality and oil yield of camellia seeds, mature camellia seeds must be fully dried before pressing or extraction. Reasonable drying can reduce the water content of camellia seeds, prevent mold and deterioration, and improve the oil yield and quality of camellia oil. Currently, the commonly used camellia seed drying equipment mostly uses traditional hot air or drum drying methods. These devices are difficult to evenly heat the camellia seeds, resulting in uneven temperature and humidity distribution in different areas during the drying process. Some camellia seeds may not be heated enough, while others may be overheated. Among them, the water content of underheated camellia seeds is high, which is easy to cause mold and deterioration during storage, while the internal oil of overheated camellia seeds may oxidize. Both underheated and overheated camellia seeds will reduce the yield and quality of camellia oil. Summary of the invention

On the other hand, the drying of the material is divided into two steps to improve the accuracy of the control of the drying degree of the material. Furthermore, the first preset degree and the second preset degree are both artificially set parameters, wherein the second preset degree is the optimal drying degree when pressing oil from camellia seeds.

[0031] The regulating component is used to dry and stir the material in the primary drying unit to improve the drying uniformity of the material in the primary drying unit, and to adjust the drying speed of the material in the secondary drying unit when stirring the material in the primary drying unit to ensure that the material can be fully dried in the secondary drying unit.

[0032] The drying device for camellia seeds of the present invention comprises the following steps: when drying the camellia seeds, the camellia seeds are transported into a drying chamber through a feeding port, the camellia seeds entering the drying chamber enter a primary drying unit, the primary drying unit performs preliminary drying on the camellia seeds, and dries the camellia seeds to a first preset degree; during the process of drying the materials in the primary drying unit, the regulating component can stir the materials to accelerate the drying of the materials; after the first drying unit dries the camellia seeds to the first preset degree, the camellia seeds enter a secondary drying unit, the secondary drying unit continues to dry the camellia seeds, and at the same time, the regulating component adjusts the drying efficiency of the secondary drying unit to ensure that the camellia seeds can quickly reach a second preset degree under the action of the secondary drying unit; after the drying degree of the camellia seeds reaches the second preset degree, the camellia seeds can leave the drying chamber through a discharging port, and the camellia seeds are dried step by step through the primary drying unit and the secondary drying unit, so that the camellia seeds can be dried to a required degree, and at the same time, the camellia seeds are prevented from being dried unevenly.

[0033] In one of the embodiments, the multi-stage drying component also includes a pre-drying unit, which is used to perform preliminary drying of the material, and the first-stage drying unit is used to dry the material after being dried by the pre-drying unit. By setting the first-stage drying unit and the second-stage drying unit, there is still extra space in the drying chamber. In order to improve the drying efficiency of the material, the pre-drying unit is arranged at the feed inlet. After the pre-drying unit pre-dries the material, the drying time of the first-stage drying unit is reduced, thereby improving the drying efficiency of the material.

[0034] In one embodiment, the pre-drying unit includes a first drying cylinder 150, which is fixedly arranged below the feed port. When the material is put into the drying chamber through the feed port, the material is directly received by the first drying cylinder 150.

The side wall of the first drying cylinder 150 is provided with a plurality of first air guide holes 151, and the heat emitted by the heating plate 140 inside the drying chamber can be radiated to the inside of the first drying cylinder 150 through the first air guide holes 151. The first drying cylinder 150 is provided with a first discharge port, which is arranged at the lower end of the first drying cylinder 150. The first drying cylinder 150 is provided with a first blocking plate 152 for blocking the first discharge port. In the initial state, the first blocking plate 152 is in a state of blocking the first discharge port. When the humidity of the material inside the first drying cylinder 150 reaches a third preset level, the first blocking plate 152 is adjusted to unblock the first discharge port. Specifically, the third preset degree is a manually set parameter, wherein the humidity of the material at the third preset degree is greater than the humidity of the material at the first preset degree. After the dryness of the material inside the first drying drum 150 reaches the third preset degree, the material inside the first drying drum 150 can now be separated from the first drying drum 150. After the material is separated from the first drying drum 150, the material can continue to be dried by the primary drying unit.
