Description

Technical Field

[0001] This utility model relates to the field of food processing, and in particular to a high-efficiency drying device for food processing. Background Technology

[0002] Food processing refers to the processing of grains, feed, vegetable oils and sugars, slaughtering and meat processing, aquatic products, and other foods such as vegetables, fruits and nuts, as well as potato processing, dehydrated vegetable processing, and canned vegetable processing, which are carried out directly using agricultural, forestry, animal husbandry and fishery products as raw materials. It is a type of agricultural product processing industry in a broad sense.

[0003] Food processing often requires drying to reduce moisture content and extend shelf life. Current drying equipment mostly uses hot air drying. However, during the drying process, the hot air needs to be exhausted, and a large amount of heat is directly discharged through the exhaust pipe, resulting in a waste of heat resources. To address this issue, we propose a high-efficiency drying device for food processing. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency drying device for food processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency drying device for food processing includes a protective outer shell. Two protective doors are hinged to the front of the protective outer shell. A drying inner shell is fixedly connected inside the protective outer shell, and a cavity is provided between the protective outer shell and the drying inner shell. An exhaust pipe is fixedly connected to the upper surface of the drying inner shell. Equally spaced air holes are provided on the inner bottom wall of the protective outer shell. A drying rack is slidably connected to the inside of the drying inner shell via a guide rail. A wind box is fixedly connected to the bottom surface of the protective outer shell. A mounting frame is fixedly connected inside the wind box, and two fans are installed inside the mounting frame. An electric heating mesh is installed inside the wind box. Two exhaust ports are fixedly installed on the back of the protective outer shell.

[0007] In a further embodiment, a base is fixedly connected to the bottom surface of the bellows, and two sets of lifting lugs are fixedly connected to the upper surface of the protective shell.

[0008] In a further embodiment, a fixed handle is rotatably connected to the front of one of the protective doors via a pin, and a fixing member is fixedly connected to the front of the other protective door, with the fixed handle engaging with the fixing member.

[0009] In a further embodiment, one of the protective doors has a display window on its front, the other protective door has a controller on its front, and the upper surface of the protective housing has an indicator light.

[0010] In a further embodiment, a maintenance plate is mounted on the back of the protective housing by screws, and an instruction label is provided on the back of the maintenance plate.

[0011] In a further embodiment, the outer surface of the bellows is provided with two sets of air inlets, and each air inlet is provided with a filter screen inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device adopts a double-layer structure design, consisting of an outer protective shell and an inner drying shell. The inner drying shell is equipped with a drying rack for placing food and is connected to an air box through evenly distributed air holes. The air box integrates a high-efficiency fan and an electric heating grid, which can generate a stable hot airflow and deliver it to the inside of the drying shell to achieve uniform drying of the food. During the drying process, the generated hot airflow is introduced into the heat-insulating cavity between the protective shell and the drying shell through a dedicated exhaust pipe, using residual heat to assist in heating the drying shell. This innovative heat recycling design not only improves the efficiency of heat energy utilization but also effectively reduces heat loss, achieving an energy-saving and environmentally friendly drying effect.

[0022] Please see Figures 1-4In this utility model, a high-efficiency drying device for food processing includes a protective outer shell 1. Two protective doors 8 are hinged to the front of the protective outer shell 1. A drying inner shell 15 is fixedly connected inside the protective outer shell 1. A cavity 17 is provided between the protective outer shell 1 and the drying inner shell 15. An exhaust pipe 16 is fixedly connected to the upper surface of the drying inner shell 15. Equally spaced air holes 20 are provided on the inner bottom wall of the protective outer shell 1. A drying rack 19 is slidably connected inside the drying inner shell 15 via a guide rail 18. A wind box 10 is fixedly connected to the bottom surface of the protective outer shell 1. A mounting frame 23 is fixedly connected inside the wind box 10. The mounting frame 23 has an internal... Two fans 22 are installed, and an electric heating grid 21 is installed inside the air box 10. Two exhaust ports 14 are fixedly installed on the back of the protective shell 1. After the equipment is started by the controller 4, the fans 22 inside the air box 10 start to operate and work together with the electric heating grid 21 to continuously deliver heated air to the inside of the drying inner shell 15. The hot air circulates between the drying racks 19 to dry the food evenly. During this process, the generated hot steam is introduced into the cavity 17 through the exhaust pipe 16 and uses the residual heat to assist in heating the drying inner shell 15, forming a highly efficient heat energy circulation system, which significantly reduces heat loss and improves energy utilization efficiency.

[0023] A base 11 is fixedly connected to the bottom of the air box 10, and two sets of lifting lugs 6 are fixedly connected to the upper surface of the protective shell 1. The base 11 and the lifting lugs 6 cooperate to facilitate the hoisting of the drying device. A fixed handle 2 is rotatably connected to the front of one of the protective doors 8 through a pin shaft, and a fixing part 3 is fixedly connected to the front of the other protective door 8. The fixed handle 2 and the fixing part 3 are engaged, and the protective door 8 is firmly locked by the linkage mechanism between the fixed handle 2 and the fixing part 3.

[0024] One of the protective doors 8 has a display window 7 on its front, and the other protective door 8 has a controller 4 installed on its front. An indicator light 5 is installed on the upper surface of the protective housing 1. A temperature sensor connected to the controller 4 is also installed in the drying inner housing 15 to monitor the drying temperature. The controller 4 is connected to the indicator light 5 through a wire, which can light up to indicate when the drying device is running. A maintenance plate 13 is installed on the back of the protective housing 1 by screws. An instruction label 12 is provided on the back of the maintenance plate 13. The drying inner housing 15 can be maintained through the maintenance plate 13. The instruction label 12 can explain the use of the drying device. The outer surface of the air box 10 has two sets of air inlets 9. Each air inlet 9 has a filter screen inside. The air inlets 9 facilitate the intake of air into the air box 10, and the filter screen can filter dust when outside air enters.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, first place the drying device stably in the operating position, ensuring that the base 11 is completely in contact with the contact surface. After connecting the power, place the food to be dried in an orderly manner on the drying rack 19 of the drying inner shell 15. Then, close the protective door 8 and securely lock the protective door 8 through the linkage mechanism of the fixed handle 2 and the fixing part 3. After starting the device through the controller 4, the fan 22 in the air box 10 starts to operate, working in conjunction with the electric heating grid 21 to continuously deliver heated air into the drying inner shell 15. The hot air circulates between the drying racks 19, drying the food evenly. During this process, the generated hot steam is introduced into the cavity 17 through the exhaust pipe 16, using the residual heat to assist in heating the drying inner shell 15, forming a highly efficient thermal energy circulation system, which significantly reduces heat loss and improves energy utilization efficiency.
