Description
Technical Field
[0001] The invention relates to the technical field of fruit and vegetable drying, and in particular to an internal circulation type fruit and vegetable drying machine. Background Art
[0002] Fruit and vegetable drying refers to the process of removing moisture from fruits or vegetables to make them dry. After drying, the storage time of fruits and vegetables can be extended, storage and transportation can be facilitated, nutrients can be retained, and the taste of fruits and vegetables can be improved. Fruits and vegetables need to be cut into certain shapes before drying to facilitate drying. Fruits and vegetables are generally cut into slices or strips before drying to increase the surface area of fruits and vegetables during drying. Existing fruit and vegetable dryers are generally drum-type fruit and vegetable dryers. When in use, the cut fruits and vegetables are placed in the drum, and hot air is blown to one end of the drum while the drum is rotated to dry them.
[0003] For long strips of fruit and vegetable strips, when the drum rotates, it cannot be guaranteed that the fruit and vegetable strips inside can be turned evenly. The surface of the fruit and vegetable slices is in contact with the hot air flow for different times, resulting in uneven heating at different positions of the fruit and vegetable strips, affecting the taste and nutritional content of the fruit and vegetable strips after drying. During drying, hot air flows from one end of the drum to the other end, resulting in different temperatures for the fruit and vegetable strips near the two ends, resulting in different drying degrees for the fruit and vegetable strips at different positions, reducing the quality of the fruit and vegetable strips after drying.

[0030] Specifically, the air pump 27 drives the gas from the fixed shell 21 through the air pipe 26 to flow into the first cavity 41, and then the air flow in the first cavity 41 is heated by the heater 42 and flows into the second cavity 46.

During drying, it can be ensured that the dried fruits and vegetables at any position are subjected to the same hot air flow temperature, thereby improving the drying quality.
[0031] In this embodiment, a sealed transmission mechanism 2 for transmitting the fruit and vegetable strips from above is disposed at the upper ends of the two first fixed plates 1 , and the sealed transmission mechanism 2 includes a fixed shell 21 .

[0033] A first electric telescopic rod 29 is symmetrically arranged at the upper ends of the two first fixed plates 1, and the telescopic ends of the four first electric telescopic rods 29 are fixedly connected to two symmetrically arranged third fixed plates 25. Two first rotating rollers 24 are rotatably arranged on the inner side surfaces of the two third fixed plates 25, and the sides of the two first rotating rollers 24 are tightly provided with a first transmission belt 22, and a plurality of equidistantly arranged fixing strips 23 are slidably provided on the sides of the first transmission belt 22. A first motor 28 is fixedly connected to the side of one of the third fixed plates 25, and the transmission shaft end of the first motor 28 is fixedly connected to a first rotating roller 24.
[0034] The outer side surface of the first transmission belt 22 is provided with a plurality of equally spaced first limiting grooves 211, and a plurality of first limiting grooves 211 are respectively fixedly connected with first pressure sensors 210, and the upper ends of a plurality of first pressure sensors 210 are respectively fixedly connected with springs 212, and the lower ends of a plurality of fixing bars 23 are fixedly connected with the upper ends of the springs 212, and a plurality of fixing bars 23 are slidably matched with the first limiting grooves 211.
[0035] Specifically, the first motor 28 drives a first rotating roller 24 to rotate, and the first rotating roller 24 drives the first transmission belt 22 to transmit, ensuring that the transmission direction of the first transmission belt 22 is opposite to the transmission direction of the second transmission belt 44, and at the same time, the four first electric telescopic rods 29 are contracted, and the extension and contraction amount of the first electric telescopic rods 29 is controlled by the first pressure sensor 210 on the side of the first transmission belt 22 to ensure that the fixed strip 23 is in contact with the surface of the fruit and vegetable strips. When the first transmission belt 22 and the second transmission belt 44 move in opposite directions, opposite friction forces can be applied to the upper and lower surfaces of several fruit and vegetable strips at the same time, thereby ensuring that several fruit and vegetable strips can rotate at a uniform speed.
[0036] In this embodiment, a feeding mechanism 3 is provided at the end of the first fixing plate 1 to facilitate the entry of fruit and vegetable strips.
[0037] Two symmetrically arranged first connecting plates 31 are fixedly connected to the side surfaces of the two first fixing plates 1, second connecting plates 32 are rotatably arranged at the ends of the two first connecting plates 31, anti-overflow plates 34 are fixedly connected to the ends of the two second connecting plates 32, and a support plate 33 is fixedly connected between the two anti-overflow plates 34.

[0039] When in use, the fruit and vegetable strips cut into uniform strips are placed on the support plate 33. The angle of the support plate 33 can be adjusted by rotating the second connecting plate 32. The anti-overflow plate 34 can prevent the fruit and vegetable strips from falling. At the same time, the second motor 412 is started, and the second motor 412 drives a second rotating roller 43 to rotate. The second rotating roller 43 drives the second transmission belt 44 to transmit. Under the action of gravity, a number of fruit and vegetable strips are moved to the second transmission belt 44. At the same time, the placement position of the fruit and vegetable strips is ensured to be perpendicular to the moving direction of the second transmission belt 44. When the fruit and vegetable strips cover the upper part of the second transmission belt 44, stop adding the fruit and vegetable strips, and at the same time turn on the first motor 28. The first motor 28 drives a first rotating roller 24 to rotate. A first rotating roller 24 drives the first transmission belt 22 to transmit, ensuring that the transmission direction of the first transmission belt 22 is opposite to the transmission direction of the second transmission belt 44, and at the same time, the four first electric telescopic rods 29 are contracted, and the extension and contraction amount of the first electric telescopic rods 29 is controlled by the first pressure sensor 210 on the side of the first transmission belt 22 to ensure that the fixed strip 23 is in contact with the surface of the fruit and vegetable strips. When the first transmission belt 22 and the second transmission belt 44 move in opposite directions, opposite friction forces can be applied to the upper and lower surfaces of several fruit and vegetable strips at the same time, thereby ensuring that several fruit and vegetable strips can rotate at a uniform speed, so that the surface of the fruit and vegetable strips is in contact with the airflow for the same time, thereby improving the quality of the fruit and vegetable strips after drying.
[0040] When the first transmission belt 22 and the second transmission belt 44 drive the plurality of fruit and vegetable strips to rotate at a uniform speed, the air pump 27 is started, and the air pump 27 drives the gas from the fixed shell 21 through the gas pipe 26 to flow into the first cavity 41. After that, the air flow in the first cavity 41 is heated by the heater 42 and flows into the second cavity 46. A plurality of second through holes 48 are connected to the second cavity 46. When the temperature sensor 49 detects that the gas temperature is the same and reaches the drying temperature, a plurality of solenoid valves 410 are started, and the hot air flow can flow to the dried fruits and vegetables between the first transmission belt 22 and the second transmission belt 44, and heat and dry them. During drying, it can be ensured that the temperature of the hot air flow received by the dried fruits and vegetables at any position is the same, thereby improving the quality of drying. When drying is completed, the first motor 28 is turned off, and the second transmission belt 44 can transmit the dried fruit and vegetable strips, which is very convenient.
