Description

Technical Field

[0001] The utility model relates to the technical field of food, in particular to a nut cleaning machine. Background Technique

[0002] The cleaning machine is mainly used for cleaning foods such as nuts and kernels to increase the cleanliness and food safety of nuts, kernels and other foods. The belt cleaning machine can continuously clean nuts without interruption, improving production efficiency. At present, for the existing belt cleaning machine, the cleaning water is in a static state, which cannot meet the requirements of deeper cleaning processes, so the cleaning is not sufficient, not fast enough, and not uniform enough, seriously affecting the cleanliness and food safety of the food.

[0003] The Chinese utility model with the publication date of August 2, 2024 and the publication number of CN221449834U proposes an ultrasonic belt flavoring machine, which includes a frame and a conveyor belt arranged on the frame. A sunken flavoring tank for containing the material water is arranged on the frame, and a sunken section is arranged on the conveyor belt to pass through the sunken flavoring tank; an ultrasonic device is arranged at the bottom of the sunken flavoring tank to oscillate the material water. Through the ultrasonic waves generated by the ultrasonic device, the material water inside the sunken flavoring tank generates cavitation effect and mechanical effect, making the material water and the material fully contact. Because the ultrasonic waves have high energy, high vibration frequency and strong penetration ability, the material water can enter the nuts or kernels faster, with a deeper flavoring level, higher flavoring efficiency, shortening the material soaking time, and making the material flavoring more uniform, improving the flavoring efficiency and production efficiency. This flavoring machine conveys the kernels through a conveyor belt and acts on the liquid in the tank through ultrasonic waves. If the liquid in the tank is replaced with clean water, it can also be used for cleaning the kernels. However, when this patent is used for cleaning the kernels, since some kernels will float on the water surface or gather together, the cleaning effect is poor. Content of the Utility Model
