Description

TECHNICAL FIELD

[0001] The embodiment of the utility model relates to the technical field of freeze-drying machine, more specifically, it relates to a high -efficient defrosting food freeze -drying machine. BACKGROUND

[0002] Food freeze-drying machine is a freeze-drying equipment that removes water in food by freeze-drying technology, and its core function is to effectively remove water in the material through low-temperature freezing and vacuum dehydration technology, while retaining its original structure, activity and nutritional ingredients.

[0003] During the freeze-drying process of the food freeze-drying machine, the water in the food will become water vapor through sublimation, and then condense into an ice layer. After long-term operation, the thickness of the ice layer will gradually increase, thereby affecting the water capture efficiency of the freeze-drying machine and increasing the energy consumption. In severe cases, it may even cause abnormal operation of the equipment. Therefore, the freeze-drying machine generally has a defrosting function. However, after defrosting, the freeze-drying machine usually discharges water through a drain. However, during the drainage process, since the bottom of the freeze-drying chamber is relatively flat, there will still be a lot of water stains remaining in the freeze-drying chamber during the drainage process. Therefore, during the next freeze-drying process, the water stains will quickly condense into ice, affecting the water capture efficiency of the freeze-drying machine and causing insufficient defrosting.

[0004] Therefore, a new solution is needed to solve this problem. UTILITY MODEL CONTENT

[0005] The purpose of the embodiment of the utility model is to provide a high-efficiency defrosting food freeze-drying machine to solve the above problems.

[0007] The utility model is further provided as follows: the driving mechanism comprises a driving motor arranged in the freeze-drying machine main body, a transmission gear is fixedly connected to the output end of the driving motor, and a rack is fixedly connected to one side of the conductive block.

[0008] The utility model is further provided as follows: a long slot is arranged in the freeze-drying machine main body and communicates with the chute, and the rack and the long slot are in sliding cooperation.

[0009] The present invention is further configured such that: two symmetrically distributed protrusions are provided at the bottom of the rotating rod, and a groove is formed between the two protrusions, and the cleaning component slides in the groove.

[0010] The present invention is further configured such that: two symmetrically distributed adjusting columns are provided on the cleaning component, the adjusting columns are slidably engaged with the cleaning component, a cavity is provided inside the cleaning component, an adjusting plate is fixedly connected to one end of the adjusting column, the adjusting plate extends out of the cleaning component, a spring is fixedly connected between the adjusting plate and the cleaning component, and a limiting hole is provided on the protrusion to engage with the adjusting column.
