Description

Technical Field

[0001] This utility model belongs to the field of dried bean curd production and processing technology, specifically a drying device for producing dried bean curd. Background Technology

[0002] Tofu skin (yuba) is a traditional soy protein product that is very popular with consumers. It is yellowish-white in color, glossy and translucent, and rich in protein and various nutrients. It is widely used in cooking and food processing. The traditional processing of tofu skin mainly includes key steps such as selecting soybeans, grinding, filtering, boiling, shaping, and drying. Among these, the drying process plays a decisive role in the texture, color and shelf life of the final product.

[0003] In the drying process, many manufacturers still use traditional drying rooms or simple drying tunnels. These devices generally have the problem of low thermal energy utilization. Their working method is often to directly introduce heated air into the drying area to dry the dried bean curd sticks, and then directly discharge the hot and humid exhaust gas containing a large amount of water vapor to the outside.

[0004] This open-type dehumidification mode not only wastes a lot of heat-carrying air, resulting in high energy consumption per unit of product, but also affects the uniformity and efficiency of drying due to unstable heat energy and emission losses, ultimately increasing the company's production costs and restricting further improvement in production efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a drying device for producing dried bean curd sticks.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model describes a drying device for producing dried bean curd sticks, including a drying chamber. The inner wall of the drying chamber is fixedly provided with a heat insulation layer. A sealing door is movably provided at one end of the drying chamber. A sealing strip is fixedly provided on the inner outer ring of the sealing door. A control panel is fixedly provided at one end of the drying chamber. Several shock-absorbing pads are fixedly provided at the bottom of the drying chamber. A heat circulation component is fixedly provided at one end of the drying chamber. The drying chamber, as the main structure of the entire device, provides a closed space for the drying process. The heat insulation layer is attached to the inner wall of the drying chamber to reduce the loss of internal heat to the outside and improve the heat energy utilization rate. The sealing door is movably provided at one end of the chamber to facilitate loading and unloading of dried bean curd stick products. The sealing strip is fixed to the inner outer ring of the sealing door to enhance the sealing performance after the door is closed and prevent heat leakage. The control panel is fixedly provided for centralized operation and setting of various drying parameters.

[0007] Preferably, the heat circulation component includes a blower box, with a blower box fixedly installed at one end of the drying chamber, and a movable frame movably installed at the end of the blower box near the drying chamber. A handle is fixedly installed on the top of the movable frame. The blower box, as part of the heat circulation component, is fixed to one end of the chamber to guide airflow. The movable frame is movably installed at the end of the blower box near the chamber to support the filter components. The handle is fixed to the top of the movable frame to facilitate the user to lift and reinstall the movable frame by hand.

[0008] Preferably, a filter screen is fixedly installed inside the movable frame, and a through hole is opened at the upper edge of the air box. The filter screen is fixedly installed inside the movable frame to intercept and remove impurities and fibers in the flowing air, and the through hole is opened at the upper edge of the air box as a channel for hot and humid air to enter and exit the air box.

[0009] Preferably, a fan is fixedly installed inside the air box, and a cover plate is movably installed at one end of the air box. The fan is fixed inside the air box to generate suction to drive the air inside the box to circulate. The cover plate is movably installed at one end of the air box to facilitate maintenance and cleaning of the inside of the air box.

[0010] Preferably, a heating fan is fixedly installed on the inner wall of the drying chamber, and several air guide strips are installed inside the air outlet of the heating fan. The heating fan is fixed to the inner wall of the drying chamber and is responsible for generating and blowing out the hot air required for drying. The air guide strips are installed inside the air outlet of the heating fan to organize and guide the direction of the hot air so that its distribution is more reasonable.

[0011] Preferably, the air guide strip has screw holes at both ends. The air guide strip is connected to the inner wall of the air outlet of the heating fan by adjusting bolts. The screw holes at both ends of the air guide strip provide an installation base for adjusting its angle. The adjusting bolts fix the air guide strip by screwing into the screw holes and can change the angle of the air guide strip by adjusting its tightness, thereby controlling the direction of hot air flow.

[0012] Preferably, a circulating air duct is fixedly provided between the air box and the heating fan, and a dehumidifier is fixedly provided on the circulating air duct. The circulating air duct is fixedly connected between the air box and the heating fan to form a closed path that allows air to return from the air box to the heating fan.

The cover plate 13 is movably installed to facilitate maintenance of the internal components of the blower box 7.

[0027] Furthermore, such as Figure 4As shown, a heating fan 14 is fixedly installed on the inner wall of the drying chamber 1. Several air guide strips 15 are installed inside the air outlet of the heating fan 14. Screw holes 16 are opened at both ends of the air guide strips 15. The air guide strips 15 are connected to the inner wall of the air outlet of the heating fan 14 by adjusting bolts 17. A circulation air duct 18 is fixedly installed between the air box 7 and the heating fan 14. A dehumidifier 19 is fixedly installed on the circulation air duct 18. The heating fan 14 generates and blows out the hot air required for drying. 15 is set inside the air outlet of the heating fan 14 to guide and distribute the direction of hot air. Screw holes 16 are opened at both ends of the air guide strip 15 to provide fixed points for angle adjustment.
