Description

Technical Field

[0001] This utility model relates to the field of drying equipment, and in particular to a drum-type drying equipment for dried fruit production. Background Technology

[0002] A drying device is a device used to remove moisture from fruits, nuts, or other foods. In the production and processing of dried fruits, drying devices are often used to remove moisture from washed fresh fruits or nuts. It evaporates moisture by heating the food and providing proper ventilation, thereby making the food drier, extending its shelf life and preventing spoilage.

[0003] In dried fruit drying equipment, drum-type dried fruit drying equipment is favored by dried fruit manufacturers because it can make the dried fruit fully tumble and heat evenly by turning the drum, avoiding local overheating or sparse drying. However, in the use of existing drum-type dried fruit drying equipment, only the bottom part of the drum is used to turn and support the dried fruit. Some of the hot air introduced into the drum does not come into contact with the dried fruit, forming thermal voids. The utilization effect of hot air drying is poor. Therefore, a drum-type drying equipment for dried fruit production is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a drum-type drying equipment for dried fruit production, which aims to improve the problem in the prior art that "only the bottom part of the drum is used to turn and support the dried fruit, and some of the hot air introduced into the drum does not come into contact with the dried fruit, forming thermal voids and resulting in poor utilization of hot air drying".

The air outlet pipe is fixedly connected to the inner wall of the mounting base, and a shield is fixedly connected to the end of the air outlet pipe away from the mounting base. A screen is fixedly connected to the inner wall of the air outlet pipe.

[0008] As a further description of the above technical solution:

[0009] The inner wall of the mounting base is provided with a discharge groove and a feed groove.

[0010] As a further description of the above technical solution:

[0011] The rotating shaft is fixedly connected to the outer wall of the motor's output shaft, and the inner sleeve is rotatably connected to the inner wall of the mounting base.

[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by setting a drying mechanism, the hot air blown out by the hot air blower can be guided to the bottom of the inner sleeve by the air guide plate, and the shield can block other directions of the hot air flow, so that the material at the bottom of the inner sleeve receives the directional penetration of the hot air, and the heat insulation pad can also prevent the heat brought by the hot air from being absorbed and dissipated by the outer sleeve, thus ensuring the utilization efficiency of the hot air.

[0022] 2. In this utility model, the feeding and discharging of dried fruit are controlled by setting a baffle plate.

[0028] 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.

[0029] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a drum-type drying device for dried fruit production, including a mounting base 1 for mounting other components. An outer sleeve 2 for sealing and blocking the internal flow of hot air is fixedly connected to the inner wall of the mounting base 1. A hot air blower 7 is mounted on the outer wall of the outer sleeve 2. The hot air blower 7 is an existing structure and can be implemented by those skilled in the art; therefore, it will not be described in detail in this case. A motor 8 for driving the inner sleeve 41 to rotate is mounted on the inner wall of the mounting base 1. A drying mechanism is provided on the inner wall of the outer sleeve 2, including a mechanism for allowing the dried fruit to dry during the drying process. The flipping assembly 4 includes a rotating shaft 42 for rotating the inner sleeve 41. The rotating shaft 42 is rotatably connected to the inner wall of the mounting base 1 and supported by the mounting base 1. The outer wall of the rotating shaft 42 is fixedly connected to the inner sleeve 41 for placing dried fruit for drying. The outer wall of the inner sleeve 41 has ventilation holes 43 for allowing hot air to enter the inner sleeve 41. The inner wall of the inner sleeve 41 is fixedly connected to a baffle plate 45 for quickly controlling the entry and exit of dried fruit from the inner sleeve 41. The inner wall of the rotating shaft 42 is fixedly connected to a pusher 44 for assisting the discharge and entry of dried fruit into the inner sleeve 41.

[0030] Reference Figure 2 and Figure 3The drying mechanism also includes an air guide assembly 3 for allowing the hot air discharged from the hot air blower 7 to enter the inner sleeve 41 from below. This allows the dried fruit inside the inner sleeve 41 to be dried better by the hot air. The air guide assembly 3 includes a heat insulation pad 31 and an air outlet pipe 33. The heat insulation pad 31 is used to prevent the heat from the hot air from being absorbed and dissipated by the outer sleeve 2. The heat insulation pad 31 is fixedly connected to the inner wall of the outer sleeve 2. An air guide plate 32 is fixedly connected to the inner wall of the heat insulation pad 31. The air guide plate 32 is used to guide the hot air delivered by the hot air blower 7 to the bottom of the inner sleeve 41. The hot air blower 7 is not located at the bottom of the outer sleeve 2 to prevent the residue of the dried fruit from falling into the inner wall of the hot air blower 7 during the drying process and affecting its use. The air outlet pipe 33 is fixedly connected to the inner wall of the mounting base 1 and is used to discharge the cooled hot air that enters the inner sleeve 41. A shield 35 is fixedly connected to the end away from the mounting base 1. The shield 35 is used to block the ventilation holes 43 in other directions of the inner sleeve 41, so that hot air can only enter from the bottom, ensuring that the hot air can contact the dried fruit evenly and stably. A screen 34 is fixedly connected to the inner wall of the air outlet 33 to prevent the dried fruit from entering the air outlet 33. The shield 35 is rotatably connected to the inner wall of the inner sleeve 41. When the inner sleeve 41 rotates, the C-shaped notch of the shield 35 is ensured to face downward. The shield 35 is set in a C-shape to ensure that the hot air only enters from the bottom of the inner sleeve 41. The air guide plate 32 is set in a C-shape and surrounds the inner sleeve 41 on the inner wall of the outer sleeve 2. The air guide plate 32 is arranged in a fan-shaped array with the hot air blower 7 as the base point, so that the hot air discharged by the hot air blower 7 can enter from the bottom of the inner sleeve 41 evenly and stably.

[0031] Reference Figure 1 and Figure 3 The inner wall of the mounting base 1 is provided with a discharge chute 6 for discharging dried fruit. The discharge chute 6 is closed when not in use to prevent hot air loss. The inner wall of the mounting base 1 is provided with a feed chute 5 for placing dried fruit into the inner sleeve 41. The feed chute 5 and the discharge chute 6 are both located on the side of the inner sleeve 41 where the baffle plate 45 is installed. The rotating shaft 42 is fixedly connected to the outer wall of the output shaft of the motor 8. The rotating shaft 42 is driven to rotate by the motor 8. The inner sleeve 41 is rotatably connected to the inner wall of the mounting base 1 to ensure that the dried fruit can enter and exit from the feed chute 5 and the discharge chute 6. The baffle plate 45 is spiral in shape. 1. When rotating, it is used to push the dried fruit. Multiple sets of baffle plates 45 are provided. The multiple sets of baffle plates 45 are arranged in a rotating array with the center line of the rotating shaft 42 as the rotation axis. The entry and discharge of dried fruit can be controlled according to the forward and reverse rotation of the motor 8. The pusher 44 is set in a spiral shape. When rotating with the rotating shaft 42, it can push the dried fruit. The pusher 44 rotates in contact with the inner wall of the shield 35. The part of the pusher 44 that is in contact with the shield 35 is made of elastic heat-resistant material. When rotating, it can contact the inner sleeve 41 through the C-shaped notch of the shield 35. When the dried fruit is discharged, it is ensured that the dried fruit on the inner sleeve 41 can be pushed away by the pusher 44.

[0032] Working principle: During use, the motor 8 is started and rotates forward. Dried fruits fall into the inner sleeve 41 through the feed chute 5. The baffle plate 45 pushes the dried fruits to diffuse into the cylinder. Then, the hot air fan 7 is started. The hot air generated by the hot air fan 7 is sent into the air guide assembly 3 through the side wall of the outer sleeve 2. The C-shaped air guide plates 32 are distributed in a fan-shaped array to evenly guide the hot air to the bottom of the inner sleeve 41. The hot air enters the cylinder through the ventilation holes 43 at the bottom of the inner sleeve 41 and directly penetrates the dried fruit layer. During this process, the motor 8 drives the rotating shaft 42 to rotate the inner sleeve 41. The spiral baffle plate 45 rotates with the inner sleeve, continuously turning and scattering the dried fruits, so that they are evenly exposed to the hot air and cooled down. Hot air is discharged through the air outlet duct 33. The screen 34 blocks dried fruit debris from entering the pipe. The heat insulation pad 31 reduces heat loss and ensures that the heat energy is concentrated in the inner sleeve 41. During the discharge stage, the motor 8 reverses and the spiral blades of the pusher 44 rotate closely against the inner wall of the shield 35, pushing the dried fruit towards the discharge trough 6. The pusher 44 is made of elastic heat-resistant material to prevent dried fruit residue. The shield 35 covers the ventilation holes 43 on the upper part and side wall of the inner sleeve 41, forcing hot air to rise only from the bottom, forming a bottom-up penetrating airflow. The side-mounted design of the hot air blower 7 prevents fruit shell debris from falling in. Combined with the fan-shaped layout of the air guide plate 32, it achieves uniform distribution of hot air.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
