Description

Technical Field

[0001] The invention belongs to the technical field of coffee drying, and in particular relates to coffee drying equipment with a uniform heating function. Background Art

[0002] Coffee is a beverage made from roasted and ground coffee beans. As one of the three major beverages in the world, it is a major beverage popular in the world along with cocoa and tea. The coffee we drink daily is made from coffee beans with various cooking utensils. Coffee beans refer to the kernels inside the fruit of the coffee tree, which are then roasted using appropriate methods. Therefore, drying equipment is needed to dry the coffee beans during the roasting process.

[0003] Most of the current coffee bean drying methods are to spread the coffee beans flat in a carrying frame and then dry them. During the drying process, the coffee beans mostly remain motionless. On the one hand, it is easy for the coffee beans to stick to the drying frame. On the other hand, the coffee beans are prone to uneven heating, resulting in uneven drying of the coffee beans, which reduces the drying effect of the drying equipment. For this purpose, a coffee drying equipment with uniform heating function is provided. Summary of the Invention

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In the present invention, a turning assembly is provided, and the rotation of the reciprocating screw causes the sliding sleeve to drive the supporting plate to move back and forth, and the supporting plate drives the fixed plate to move back and forth, and the fixed plate drives the shovel plate to move back and forth inside the carrying frame through the spring rod. When the spring rod acts, the bottom surface of the shovel plate is always in contact with the bottom surface of the carrying frame. When the shovel plate moves back and forth, it can effectively prevent the coffee beans from sticking to the bottom surface of the carrying frame during the drying process, thereby ensuring the drying quality of the coffee beans. When the shovel plate moves, the transmission gear drives the stirring plate to rotate through the telescopic rod under the action of the fixed rack. At this time, the stirring plate can realize stirring of the coffee beans in the carrying frame. On the one hand, the coffee beans can be turned over, thereby ensuring the uniformity of drying the coffee beans. On the other hand, when stirring the coffee beans, the clumped coffee beans can be broken up, thereby ensuring the drying effect of the coffee beans.

[0026] 2. In the present invention, a vibration component and a drying component are provided. When the reciprocating screw rotates, it drives the rotating disk to rotate, and the rotating disk drives the top block to rotate synchronously. Under the action of the top rod, the connecting column drives the supporting frame to move. Under the action of the slider and the supporting spring, the supporting frame vibrates up and down, thereby realizing vibration during the coffee bean drying process. On the one hand, it can ensure that the coffee beans in the supporting frame are evenly distributed, avoiding excessive accumulation in some places, resulting in uneven drying. On the other hand, the vibration can also make the coffee beans loose during the drying process, ensuring the flow of hot air between the coffee beans, which not only improves the drying uniformity of the coffee bean drying equipment, but also improves the drying speed of the coffee beans.

[0027] 3. In the present invention, by providing a drying component, the heating cylinder generates heat and rotates itself at the same time, and the rotation drives the inner gear ring to rotate synchronously. At this time, the rotating rod rotates under the action of the rotating gear, and the rotating rod drives the fan blades to rotate synchronously. As the fan blades rotate, the heat generated by the heating cylinder is blown toward the middle of the drying barrel, thereby concentrating the heat generated by the drying equipment. On the one hand, it reduces the heat loss of the drying equipment and improves the full utilization rate of the heat of the drying equipment. On the other hand, the heat is concentrated to dry the coffee beans, which can effectively improve the overall drying speed of the coffee beans and further improve the working efficiency of the drying equipment.
