Description

Technical Field

[0001] The utility model relates to the technical field of drying machines, in particular to a constant temperature drying machine. Background Art

[0002] Drying is the process of removing moisture from materials while retaining the solid content. This process typically involves passing hot air through the material to evaporate and remove the moisture. Drying typically requires the use of a dryer. There are many types of dryers available, one of which is a constant temperature dryer. Constant temperature dryers maintain a constant drying temperature and dry items evenly, making them commonly used for drying food, fruits, and vegetables.

[0003] However, the current constant temperature dryer has certain shortcomings when in use. The existing constant temperature dryer generally has a drying grid inside, and when in use, the food is generally placed on the drying grid. This method of drying food is relatively simple. When drying some foods with relatively high internal moisture, the internal moisture will drip downward and fall on the food below. Therefore, the food below will be exposed to more moisture. At the same time, the drying time is relatively long and the drying time of the food inside the constant temperature drying box is different, so the food drying time is prolonged and the food drying efficiency is reduced. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a constant temperature dryer, which solves the problem of moisture from the upper food dripping onto the food below the drying box when drying food with relatively high moisture content. Therefore, it avoids the food inside the drying box from drying at different speeds, prevents the food drying time from being prolonged and reduces the food drying efficiency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a constant temperature dryer, comprising a drying box, a support frame is provided inside the drying box, and two groups of drying plates are provided side by side on the inner side of the support frame, both ends of the drying plates are fixedly connected with rotating shafts, and one end of the rotating shaft is rotatably connected to the inner surface of the support frame, the upper surface of one end of the drying plate is fixedly connected to the support frame, and the inner surface of the support frame is fixedly connected to a number of support rods, the upper surface of the other end of the drying plate is fixedly connected to a material receiving trough, and the width of the material receiving trough is greater than the width of the support frame, a cleaning mechanism is provided inside the material receiving trough, a limiting mechanism is fixedly installed on one side surface of the drying plate, and a box door is installed on the front side surface of the drying box.

[0006] Preferably, the cleaning mechanism includes a motor, and the motor is fixedly mounted on the upper surface of the support frame, one end of the motor is fixedly connected to a reciprocating screw through the material receiving trough, and one end of the reciprocating screw is rotatably connected to the inner surface of the material receiving trough, the side surface of the reciprocating screw is threadedly connected to a movable plate, and the lower end of the movable plate is fixedly connected to a cleaning brush.

[0007] Preferably, the length of the cleaning brush matches the width of the interior of the receiving trough.

[0008] Preferably, the limiting mechanism includes a limiting hole, and a limiting rod is provided inside the limiting hole, the side surface sliding sleeve of the limiting rod is provided with a fixing plate, and the fixing plate is fixedly connected to the upper surface of the drying plate, one end of the limiting rod is fixedly connected to a reset spring, and one end of the reset spring is fixedly connected to one side surface of the fixing plate.

[0009] Preferably, a slide groove is symmetrically fixedly connected to the inner surface of the drying box, and a slider is slidably connected inside the slide groove, and one side surface of the slider is fixedly connected to the outer surface of the support frame.

[0010] Preferably, a sewage main pipe is fixedly installed inside the drying box, and a number of sewage branch pipes are fixedly installed on the side surface of the sewage main pipe, one end of the sewage branch pipe is fixedly connected to the material receiving trough, and a collecting trough is installed on the rear side surface of the drying box, and one end of the sewage main pipe passes through the drying box and is located inside the collecting trough.

[0012] 1.

Therefore, it avoids the food inside the drying box from drying at different speeds, prevents the food drying time from being prolonged and reduces the food drying efficiency.

[0013] 2. Through the reciprocating screw, cleaning brush and movable plate in the cleaning mechanism inside the receiving trough, the motor, the drainage branch pipe under the receiving trough and the drainage main pipe inside the drying box, the moisture and impurities inside the receiving trough can be easily cleaned, thereby ensuring the sanitary environment inside the drying box and the receiving trough, and preventing the quality of subsequent food drying from being affected.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides a technical solution: a constant temperature drying machine, comprising a drying box 1, wherein the drying box 1 is provided with a support frame 7, and two groups of drying plates 8 are arranged side by side on the inner side of the support frame 7, both ends of the drying plates 8 are fixedly connected with a rotating shaft 701, and one end of the rotating shaft 701 is rotatably connected to the inner surface of the support frame 7, the upper surface of one end of the drying plate 8 is fixedly connected to a support frame 801, and the inner surface of the support frame 801 is fixedly connected to a plurality of support rods 802, the upper surface of the other end of the drying plate 8 is fixedly connected to a material receiving trough 2, and the width of the material receiving trough 2 is greater than the width of the support frame 801, a cleaning mechanism is provided inside the material receiving trough 2, and a limiting mechanism is fixedly installed on one side surface of the drying plate 8, and a box door 4 is installed on the front side surface of the drying box 1.

[0022] As a technical optimization solution of the present invention, the cleaning mechanism includes a motor 10, and the motor 10 is fixedly mounted on the upper surface of the support frame 7. One end of the motor 10 passes through the material receiving trough 2 and is fixedly connected to a reciprocating screw 1001, and one end of the reciprocating screw 1001 is rotatably connected to the inner surface of the material receiving trough 2. The side surface of the reciprocating screw 1001 is threadedly connected to a movable plate 1003, and the lower end of the movable plate 1003 is fixedly connected to a cleaning brush 1002. When the motor 10 is started, the reciprocating screw 1001 can drive the cleaning brush 1002 to move inside the material receiving trough 2, thereby cleaning impurities and accumulated water inside the material receiving trough 2, thereby improving the cleanliness of the inside of the material receiving trough 2 and the inside of the drying box 1.

[0023] As a technical optimization solution of the present invention, the length of the cleaning brush 1002 matches the width of the interior of the receiving trough 2, thereby limiting the position of the cleaning brush 1002 and preventing the reciprocating screw 1001 from rotating when the motor 10 drives the cleaning brush 1002 to rotate, thereby preventing the receiving trough 2 from being cleaned. The reciprocating screw 1001 and the movable plate 1003 are threadedly engaged, and the rotation of the reciprocating screw 1001 is converted into linear movement of the movable plate 1003.

[0024] As a technical optimization solution of the present invention, the limiting mechanism includes a limiting hole 702, and a limiting rod 1101 is provided inside the limiting hole 702. The side surface sliding sleeve of the limiting rod 1101 is provided with a fixed plate 11, and the fixed plate 11 is fixedly connected to the upper surface of the drying plate 8. One end of the limiting rod 1101 is fixedly connected to a return spring 1102, and one end of the return spring 1102 is fixedly connected to one side surface of the fixed plate 11, which can limit the drying plate 8 and prevent the drying plate 8 from rotating when the drying plate 8 horizontally dries food with relatively low moisture, causing the food on the upper surface of the drying plate 8 to scatter.

[0025] As a technical optimization solution of the present invention, the inner surface of the drying box 1 is symmetrically fixedly connected with a slide groove 5, and the inside of the slide groove 5 is slidably connected with a slider 9. One side surface of the slider 9 is fixedly connected to the outer surface of the support frame 7, which can support the support frame 7 and facilitate the support frame 7 to be taken out or installed inside the drying box 1 for the convenience of staff operation.

[0026] As a technical optimization solution of the present invention, a sewage main pipe 6 is fixedly installed inside the drying box 1, and a number of sewage branch pipes 3 are fixedly installed on the side surface of the sewage main pipe 6. One end of the sewage branch pipe 3 is fixedly connected to the material receiving trough 2. A collecting trough 12 is installed on the rear side surface of the drying box 1, and one end of the sewage main pipe 6 passes through the drying box 1 and is located inside the collecting trough 12. The water inside the material receiving trough 2 can be discharged from the interior of the drying box 1 through the sewage branch pipe 3 and the sewage main pipe 6, and the moisture can be collected through the collecting trough 12.

[0027] When the present invention is in use, when drying ordinary food, it is only necessary to place the food on the upper surface of the drying plate 8, and then install the support frame 7 inside the drying box 1 to dry it. When drying food with relatively high moisture content, the staff first pulls the limit rod 1101 in the limit mechanism. At this time, one end of the limit rod 1101 will be out of the limit hole 702, and at the same time, the drying plate 8 is in a vertical state through the rotating shaft 701 due to the gravity of the receiving trough 2. Then the staff hangs the dried food on the support rod 802 with a rope or a hook, so that the receiving trough 2 will be below the dried food. At this time, when the moisture on the food is reduced, it will fall into the inside of the receiving trough 2, and then be transported to the inside of the sewage pipe 6 through the sewage branch pipe 3 on the lower surface of the receiving trough 2, so that the sewage pipe 6 discharges the moisture from the interior of the drying box 1 and flows into the inside of the collecting trough 12 for collection. During the drying process, the staff can start the motor 10, so that the motor 10 drives the cleaning brush 1002 to move through the reciprocating screw 1001, thereby cleaning the inside of the receiving trough 2.
