Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drying technology for food production, and in particular relates to a drying device for food production. Background Technology
[0002] Food drying refers to a process of removing solvents or moisture while retaining solids. It usually involves passing hot air through the food to evaporate and remove the moisture. Food drying technology significantly shortens the time required for dehydrating food products, thus accelerating the production of the final food product.
[0003] Existing drying equipment is difficult to effectively reuse heat during use, resulting in a large amount of heat loss and high energy consumption. Therefore, a drying device for food production is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a drying device for food production to solve existing problems.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a drying device for food production, comprising a heating chamber, an air blowing duct connected to one side of the heating chamber, an exhaust fan connected to one side of the heating chamber, a drying chamber located at the back of the heating chamber, a collection chamber formed on the bottom surface of the drying chamber, a drain outlet on the bottom surface of the drying chamber, a dehumidifying filter inserted inside the drying chamber, a second connecting pipe connecting the drying chamber to the air blowing duct, a first connecting pipe connecting the drying chamber to the exhaust fan, a vent pipe connected to the upper surface of the heating chamber, a support frame provided on the circumferential side of the inner wall of the vent pipe, a rod inserted through the middle of the support frame, a spring sleeved on the circumferential side of the rod, and a piston at the top of the rod.
[0007] Furthermore, the heating box is equipped with multiple heating boxes, each containing a drawer, and multiple heating tubes. A cavity is formed on the bottom surface of the heating box, and a hot air blower is installed on one side of the heating box.
[0008] Furthermore, the two ends of the second connecting pipe are respectively connected to one side of the drying box and one side of the blower pipe, one end of the first connecting pipe is connected to one side of the drying box, and the other end of the first connecting pipe is connected to one end of the exhaust fan outlet.
[0009] Furthermore, the shape and size of the drawer box are adapted to the heating box, one end of the exhaust fan is connected to one side of the heating box, one side of the blower pipe is connected to one side of the heating box, one end of the hot air blower is connected to one side of the heating box, the shape and size of the piston are adapted to the opening of the vent pipe, one end of the spring is fixedly connected to the bottom surface of the support frame, a push plate is provided at the bottom end of the insert rod, the other end of the spring is fixedly connected to the upper surface of the push plate, and the vent pipe is connected to the upper surface of the heating box.
[0010] This utility model has the following beneficial effects:
[0011] This invention heats and dries the food placed in the drawer by simultaneously activating the heating element and the hot air blower. The hot air blown by the hot air blower rises inside the heating chamber, and some water vapor is also generated during the heating process. The exhaust fan then extracts the rising water vapor, which then enters the drying chamber through the first connecting pipe. The water vapor passes through the dehumidifying filter to ensure a proper drying environment. Afterward, it returns to the heating chamber through the second connecting pipe and the air blowing pipe, thereby improving the airflow inside the drying device and increasing the drying efficiency of the equipment.
[0012] During operation, the hot air blower continuously blows air into the heating chamber. Under the action of the vent pipe, the heating chamber maintains a certain pressure. When the pressure inside the heating chamber is high during the dehumidification process, the spring is compressed, and the pressure pushes the piston upward. The opening of the vent pipe opens to release the excess pressure, thereby reducing heat loss inside the heating chamber and ensuring the flow of hot steam during the circulation process, thus improving the drying effect.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
