AI Technical Summary
Traditional flour drying equipment has only one ventilation opening, which prevents hot and humid air from escaping in time, leading to saturation of humidity inside the drum and flour clumping. In addition, adding ventilation ducts will increase the risk of seal failure and increase costs.
Design a flour drying device that uses a rotatable discharge port on the cover to switch the position of the discharge port, thus achieving two uses: as a ventilation port to discharge moisture.
It improves dehumidification efficiency, avoids humidity saturation and flour clumping, simplifies the structure and reduces costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of flour processing technology, specifically a flour drying device. Background Technology
[0002] In flour drying processes, the rapid removal of hot and humid airflow directly affects drying efficiency. Traditional equipment (such as inclined drying drums) generally suffers from the following drawbacks:
[0003] Limited number of ventilation openings: Relying solely on a single fixed ventilation opening on the top or side wall of the cylinder for moisture removal, when processing flour with high moisture content, the hot and humid air cannot escape in time, leading to:
[0004] The humidity inside the drum is saturated, extending the drying time.
[0005] Moisture condenses on the surface of flour particles, causing them to clump and spoil.
[0006] Structural redundancy: In order to improve exhaust efficiency, some equipment has additional ventilation ducts, but this increases the risk of seal failure and manufacturing costs.
[0007] Therefore, there is an urgent need for a device that can dynamically increase the number of effective ventilation openings to accelerate the discharge of hot and humid air without changing the structural complexity. Utility Model Content
[0008] The purpose of this invention is to provide a drying device for flour processing to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A flour drying device includes an inclined drying cylinder for holding flour. A coaxially mounted rotating shaft is installed inside the drying cylinder. A spiral stirring blade, which rotates synchronously with the rotating shaft, is fixed to the surface of the shaft. The rotating shaft is a heating rod. The top of the drying cylinder is mounted on a bracket, and a rotatable cover is installed at the bottom of the drying cylinder. The cover has a discharge port. During drying, the discharge port rotates with the cover and moves to the upper part of the cover, at which point the discharge port can serve as a ventilation opening to discharge moisture generated during drying.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention achieves a dual-purpose function by switching the position of the discharge port, and improves dehumidification efficiency by adding ventilation openings. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-3 In this embodiment of the present invention, a flour drying device includes an inclined drying cylinder 2 for holding flour. A rotating shaft 7 is rotatably mounted inside the drying cylinder 2. A spiral stirring blade 8 that rotates synchronously with the rotating shaft 7 is fixed on the surface of the rotating shaft 7. The rotating shaft 7 is a heating rod. The top of the drying cylinder 2 is mounted on the top of the rotating shaft 7 through a bracket. A rotatable baffle 4 is installed at the bottom of the drying cylinder 2. A discharge port is opened on the baffle 4. During drying, the discharge port rotates with the baffle 4 and moves to the upper part of the baffle 4. At this time, the discharge port can serve as a ventilation port to discharge the moisture generated during drying.
[0018] This invention achieves a dual-purpose function by switching the position of the discharge port, and improves dehumidification efficiency by adding ventilation openings.
[0019] The top end of the rotating shaft 7 is connected to the drive shaft of the motor via an insulated coupling, and the motor is fixed on a bracket at the top of the drying cylinder 2.
[0020] The drying cylinder 2 is fixed to the base 1 by the support foot 3.
[0021] The outer side of the cover 4 is provided with a handle 5 that can only rotate along the plane passing through the axis of the drying cylinder 2. One end of the handle 5 is hinged to the outer side of the cover 4. When rotating the cover 4, it can be operated through the handle 5.
[0022] The drying cylinder 2 is fixed with a locking block 6 at the position corresponding to the upper part of the cover 4 for fixing the handle 5. When the discharge port moves to the upper part of the cover 4, the handle 5 can be fixed by the locking block 6.
[0023] The card block 6 has an L-shaped card slot, and one end of the card slot forms an opening on the side of the card block 6. When the handle 5 is fixed, the handle 5 is locked in the L-shaped card slot.
