Description

Technical Field

[0001] The utility model relates to the technical field of apple slice processing, in particular to a combined drying device for processing semi-dried apple slices. Background Art

[0002] Apple slice drying means cutting fresh apples into thin slices and then gradually evaporating the moisture through hot air or other means to extend the shelf life and increase the taste. These dried apple slices can be eaten directly as snacks or as raw materials in food processing.

[0003] After searching, application number CN202222839419.9 discloses a drying device for producing semi-dried apple slices. The device can keep the semi-dried apple slices in motion during the drying process, so that the surface is heated evenly, thereby improving the drying effect.

[0004] However, the inventors have discovered that the prior art still has the following defects:

[0005] When the drying device in the prior art is in use, the hot air blower blows hot air downward, and the air duct of the hot air blower is very short, which leads to low efficiency of hot air output and seriously affects the drying efficiency.

[0006] Therefore, we propose a combined drying equipment for processing semi-dried apple slices. Utility Model Content

[0007] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a combined drying device for processing semi-dried apple slices.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a combined drying device for processing semi-dried apple slices, comprising a device housing, a feeding port for feeding apple slices to be dried is provided on the front side of the device housing, a discharging port for taking out the dried apple slices as finished products is provided on the side of the outside of the device housing opposite to the feeding port, a transmission wheel connected to two wall surfaces of the device housing through a rotating shaft is arranged inside the device housing, a mesh conveyor belt is connected to the two sets of transmission wheels, and a driving motor connected to the rotating shaft of one set of transmission wheels and driving the transmission wheels is installed on the inner wall surface of the device housing;

[0009] An air inlet duct with a "U"-shaped structure is installed at the inner top of the equipment shell, and an air supply duct for supplying air downward is connected downwardly to the bending part of the air inlet duct, a fan for blowing air downward is installed at the position of the air supply duct, and a row of electric heating rods for heating the air are installed on the inner wall of the air inlet duct, a conveying hood is connected to the lower end of the air supply duct and the position of the conveying hood corresponds to the upper end surface of the conveyor belt, and a plurality of groups of laterally arranged air outlet slots are provided at the lower end of the conveying hood.

[0010] Preferably, an inclined partition plate is provided inside the conveying cover, and the partition plate divides the inside of the conveying cover into two spaces.

[0011] Preferably, the upper end of the partition plate corresponds to the center of the fan.

[0012] Preferably, dust-proof filters are installed at the two groups of air inlet positions of the air inlet duct to prevent external dust from entering the interior of the device.

[0013] Preferably, a side window with heat-insulating transparent glass installed inside is provided on the side surface of the equipment housing at a position corresponding to the conveyor belt.

[0014] Beneficial Effects

[0015] The utility model provides a combined drying device for processing semi-dried apple slices, which has the following beneficial effects:

[0016] (1) In the combined drying equipment for processing semi-dried apple slices, the conveyor belt is arranged in a mesh shape, which can increase the contact area between hot air and apple slices and improve the drying efficiency. The air inlet pipe is arranged in a "U" shape to realize air intake from two air inlets, and the air from the two air inlets can be heated by electric heating rods, thereby improving the efficiency of hot air generation and thus improving the drying efficiency.

[0017] (2) The combined drying equipment for processing semi-dried apple slices can divide the hot air into two groups by setting a partition plate, wherein half of the hot air is directly transported vertically downward and discharged through the air outlet slot corresponding to the lower end of the fan. The hot air of this part has a short travel distance and can maintain a high heat contact with the apple slices to achieve rapid drying. The other half of the hot air is guided by the partition plate to flow to the air outlet slot position close to the discharge port and blown downward. The hot air of this part has a long travel distance, resulting in a lower temperature and a lower wind speed. Through two dryings at different temperatures and wind speeds, the uniform drying of the apple slices can be better ensured. The initial high-temperature and high-wind speed drying helps to quickly remove surface moisture, while the secondary drying at low temperature and low wind speed can gradually evaporate the internal moisture, so that the entire apple slice is dried more evenly.

[0028] When in use, the apple slices to be processed are put into the equipment through the feed port 2. After entering the equipment, the apple slices fall onto the conveyor belt 6 and move to the side of the discharge port 3 as the conveyor belt 6 runs. After all the electric heating rods 12 are energized, they heat the air inside the air inlet pipe 8. As the fan 11 runs, the heated air is transported to the inside of the conveying cover 9 through the air supply pipe 10 and blown downward through the air outlet slot 14 to dry the apple slices. Setting the conveyor belt 6 in a mesh shape can increase the contact area between the hot air and the apple slices, thereby improving the drying efficiency. Setting the air inlet pipe 8 in a "U" shape can realize air intake from two air inlets, and the air at the two air inlets can be heated by the electric heating rods 12, thereby improving the efficiency of hot air generation, thereby improving the drying efficiency.

[0029] Embodiment 2: Based on the above embodiment, Figure 4 As shown, a partition plate 15 in an inclined state is provided inside the conveying cover 9 , and the partition plate 15 divides the inside of the conveying cover 9 into two spaces, and the upper end of the partition plate 15 corresponds to the center position of the fan 11 .

[0030] By setting the partition plate 15, the hot air can be divided into two groups, half of which is directly transported vertically downward and discharged through the air outlet slot 14 corresponding to the lower end of the fan 11. The hot air of this part has a short stroke and can maintain a high heat in contact with the apple slices to achieve rapid drying. The other half of the hot air is guided by the partition plate 15 to flow to the air outlet slot 14 position close to the side of the discharge port 3 and blown downward. This part of the hot air has a longer stroke, resulting in a lower temperature and a lower wind speed. Through two dryings at different temperatures and wind speeds, the uniform drying of the apple slices can be better ensured. The initial high-temperature and high-wind speed drying helps to quickly remove surface moisture, while the secondary drying at a low temperature and low wind speed can gradually evaporate the internal moisture, so that the entire apple slice is dried more evenly.

[0031] Embodiment 3: Based on the above embodiment, Figure 3 As shown, dust-proof filters 13 are installed at the two groups of air inlet positions of the air inlet pipe 8 to prevent external dust from entering the interior of the device.
