Description

Technical Field

[0001] This utility model belongs to the field of pie processing technology, specifically relating to a drying device for pie processing. Background Technology

[0002] In the pie-making industry, traditional drying is typically done using an oven. Ovens are equipped with heating elements, and the operating temperature is usually controlled between 60-80℃, where pies need to be baked for 1-2 hours. During baking, the oven produces fumes that need to be exhausted through a ventilation system. However, traditional ventilation systems are often simply a fixed hood installed on top of the oven. When the oven is large, the distance between the baking trays and the hood's intake is often considerable, preventing timely exhaust of the fumes. These fumes accumulate inside the oven and may eventually seep into the pies. Once inside, these fumes negatively impact the taste, causing a burnt or unpleasant odor. Furthermore, inadequate ventilation can increase humidity inside the oven, affecting not only the drying process but also the appearance and shelf life of the pies. Utility Model Content

[0003] The purpose of this invention is to provide a drying device for pie processing to solve the problems existing in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A drying apparatus for pie processing, comprising:

[0006] An oven with heating rods installed on its inner walls;

[0007] The lifting mechanism, located inside the oven, includes a lifting motor, a lead screw, a lead screw sleeve, a guide rod, and a lifting connecting plate. The lifting motor drives the lead screws on both sides to rotate synchronously via a synchronous shaft. The lead screw sleeve is fitted onto the lead screw and fixed to the lifting connecting plate. The guide rod is fixed between the upper and lower supports. The lifting connecting plate is slidably connected to the guide rod via the guide sleeve.

[0008] The ventilation mechanism includes an exhaust fan, an exhaust hose, and an air box. The air box is fixed on both sides of the lifting connecting plate and its front and rear positions can be adjusted by adjusting the plate and fastening bolts. The air box has adjustable louvers at the air inlet. The exhaust fan is connected to the air box through the exhaust hose.

[0009] Preferably, the synchronous shaft of the lifting mechanism is provided with gear pairs at both ends, and the gear pairs mesh with the lead screws on both sides to realize synchronous drive of the two lead screws.

[0010] Preferably, the adjusting plate has an L-shaped structure, and the bellows is fixed to preset positions on both sides of the lifting connecting plate by fastening bolts.

[0011] Preferably, the louvers of the bellows are rotatable blades, and the air inlet angle can be adjusted manually or electrically.

[0012] Preferably, a lubricating coating is provided between the guide rod and the guide sleeve to reduce the frictional resistance when the lifting connecting plate moves.

[0013] Preferably, the power of the exhaust fan is 0.5-2kW, and the exhaust hose is made of high-temperature resistant silicone material.

[0014] The beneficial effects of this utility model are as follows: This patent achieves dynamic matching between the position of the bellows and the baking tray by setting a liftable exhaust mechanism inside the oven, significantly improving the efficiency of smoke emission. Specific beneficial effects include: 1) The bellows can be flexibly adjusted according to the height of the baking tray by a lifting motor-driven screw mechanism, shortening the smoke exhaust distance and preventing smoke stagnation; 2) Adjustable louvers at the front of the bellows allow for adjustment of the air intake angle according to baking needs, optimizing smoke collection; 3) The use of a synchronous shaft and guide rod structure ensures smooth movement of the bellows, preventing vibration from affecting smoke exhaust stability; 4) The bolted connection design between the bellows and the adjustment plate supports fine-tuning of the front and rear positions, enhancing adaptability to different sized baking trays; 5) Efficient smoke exhaust reduces smoke contamination of the pie surface, maintaining product flavor, while improving drying uniformity and extending shelf life. This design breaks through the limitations of traditional fixed exhaust systems, significantly improving the baking environment through multi-dimensional dynamic adjustment.

[0018] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0019] like Figure 1 As shown, a drying device for pie processing includes an oven 1 with a rectangular box structure, in which quartz heating rods are evenly distributed on the inner wall, and a pull-out multi-layer baking tray support is provided at the bottom of the oven. The key improvement lies in the built-in lifting and exhaust system.

[0020] The lifting mechanism 2 adopts a dual-screw synchronous drive structure, including:

[0021] A servo motor 21, mounted on the outer side of the rear wall of the oven, is connected to a synchronous shaft 26 arranged laterally at the bottom via a coupling. A gear pair 27 is installed at each end of the synchronous shaft to transmit rotational motion to longitudinally parallel lead screws 28. The lead screws 28 are fixed between an upper support 23 and a lower support 24 via bearing seats, with the upper support fixed to the top of the oven. A lead screw sleeve 22 is rigidly connected to a lifting connecting plate 25, with a guide sleeve hole in the center of the connecting plate for sliding engagement with four guide rods 29.

[0022] The exhaust system 3 consists of the following parts:

[0023] A centrifugal exhaust fan 31, mounted on top of the oven, is connected to an adjustable air box 33 via a flexible exhaust hose 32. The air box is made of aluminum alloy and has an internal guide plate with a rectangular air intake at the front. The air box is connected to a lifting connecting plate 25 via an L-shaped adjusting plate 34, which has oblong holes and fastening bolts. A louvered assembly 35, which can rotate 90° and includes five parallel guide vanes, is installed at the air intake.

[0024] The operator inputs the target height of the air box on the human-machine interface according to the number of baking tray layers, and the system automatically calculates and generates control commands. Temperature and humidity sensors collect real-time environmental data inside the oven, providing a basis for subsequent airflow adjustment. After receiving the command, the servo motor 21 drives the synchronous shaft 26 to rotate, and transmits power to the left and right lead screws 28 through the gear pair 27. The lead screw sleeve 22 drives the lifting connecting plate 25 to move vertically along the guide rod 29, so that the air box 33 is lowered to a position 30-50cm away from the target baking tray. The encoder provides real-time feedback on the lead screw rotation angle to ensure positioning accuracy of ±2mm. The stepper motor drives the louver assembly 35 to rotate, and automatically adjusts the blade angle (0°-90°) according to preset parameters or baking tray position data, so that the air intake is aligned with the main smoke generation area. At the same time, the front and rear positions of the air box can be manually fine-tuned through the waist-shaped hole of the adjustment plate 34 to adapt to different sized baking trays. After the exhaust fan 31 is started, high-speed airflow enters the air box 33 through the flexible hose 32, and its internal guide plate evenly distributes the airflow to the rectangular air intake. When the temperature and humidity sensor detects that the humidity exceeds the standard, the frequency converter automatically increases the speed of the exhaust fan, with a maximum wind speed of up to 25m / s, to ensure that water vapor and grease fumes are quickly discharged.

[0025] This principle breaks through the traditional fixed smoke exhaust mode. Through three-dimensional collaborative control with height self-adaptation, angle adjustment, and wind speed intelligent matching, the smoke residence time is shortened by more than 60%, significantly improving the cleanliness of the baking environment and product consistency.

[0026] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
