Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating equipment technology, and in particular to a uniform heating device for drying cocoa beans. Background Technology
[0002] The equipment for uniformly heating and drying cocoa beans mainly involves the following aspects: Cocoa beans are rich in nutrients such as fat, protein, carbohydrates, minerals, and various vitamins. During the drying process, if the temperature is too high, the time is too long, or the drying method is improper, these nutrients can be easily destroyed, affecting the quality and nutritional value of the cocoa beans. For example, proteins may denature at high temperatures, and fats may oxidize and become rancid, thus altering the taste and flavor of the cocoa beans. Cocoa beans have a unique flavor and aroma, mainly composed of alkaloids, phenolic compounds, and other components. During the drying process, it is necessary to precisely control parameters such as temperature, humidity, and time to ensure that these flavor substances are preserved; otherwise, the cocoa beans may lose their flavor, reducing their commercial value. Cocoa beans are relatively small in size, oval or round in shape, and have a certain degree of curvature on the surface. This shape makes heat transfer inside the cocoa bean relatively difficult, easily leading to localized overheating or under-drying. Therefore, the drying equipment needs to be able to evenly distribute hot air around each cocoa bean to ensure uniform drying. The thick and hard outer shell of the cocoa bean also hinders the rapid dissipation of internal moisture to some extent. When designing drying equipment, it is necessary to consider how to improve the efficiency of heat transfer so that moisture can be smoothly transferred from the inside to the outside of the cocoa beans, while avoiding problems such as cracking of the cocoa beans during the drying process due to the hard outer shell.
[0003] Drying is a crucial step in the processing of cocoa beans. Traditional drying methods often have many problems, such as uneven heating, which leads to some cocoa beans being over-dried while others are not yet at the appropriate humidity, affecting the quality of the cocoa beans and subsequent processing. Moreover, some drying equipment has poor dehumidification, making cocoa beans susceptible to the effects of a humid environment during the drying process, reducing their flavor and shelf life. Therefore, we propose a cocoa bean drying uniform heating device to solve this problem. Utility Model Content

[0013] In this utility model, a cocoa bean drying and uniform heating device is described. The cocoa beans to be dried are evenly placed on a filter screen in a placement drawer. The placement drawer is slidably installed between T-shaped slide bars, allowing the user to easily pull out or push in the placement drawer as needed for loading or removing cocoa beans. Next, the door panel is closed, and the inclined slot on the door panel matches the buckle inside the outer shell. When the door panel is closed, the buckle automatically springs into the inclined slot under the action of a spring, firmly locking the door panel onto the outer shell. Then, the heating screw is activated to generate heat, causing the motor to drive the fan blades to rotate and generate airflow. The moisture in the airflow is condensed into water droplets by the condenser plate. The airflow passes through the drying ventilation box in the connecting pipe for drying treatment, and then enters the outer shell through the airflow holes on the outer shell and the fan cover, accelerating the airflow around the cocoa beans and improving the drying efficiency, thereby maintaining the dryness of the airflow. After being heated by the heating screw, the dried airflow forms hot air, which evenly heats and dries the cocoa beans.

By starting motor two, the output end of motor two drives a large gear to rotate through connecting rod one, connecting rod two, and connecting rod three. The large gear meshes with a small gear, which in turn drives a toggle plate fixedly connected to the small gear to rotate. Since multiple toggle plates are connected by connecting rods, they rotate synchronously, causing the toggle plates to swing continuously. In conjunction with the ventilation pipe inside the outer shell, motor one and the fan inside the fan cover are started, working in conjunction with the connecting pipe and the drying ventilation box to achieve circulation and enhance the drying effect. After drying is completed, the heating screw and motor two are turned off, the lever is pulled to unlock the door panel, the door panel is opened, and then the storage drawer is pulled out to take out the dried cocoa beans. The rubber ring enhances the sealing between the door panel and the outer shell to prevent hot air leakage.
[0015] This utility model has a reasonable structural design. By combining a drying ventilation box and a condenser, it can effectively remove moisture from the air, providing a dry drying environment for cocoa beans. It also allows for hot air circulation inside the device, which better maintains the dry environment inside the equipment, thus achieving efficient and uniform drying and heating treatment of cocoa beans.
