[0002] During the food inspection and testing process, according to the implementation rules of food safety supervision and random inspections and the requirements of national food safety standards such as GB 2760, GB 2761, GB 2762, and GB 19300, when testing for food additives, aflatoxin B1, pollutants, acid value, peroxide value, microorganisms, etc., roasted melon seeds and nut products need to use mechanical means to remove the inedible part and then take the edible part after crushing and other processing before testing.
[0003] At present, most laboratories use manual shelling to obtain the required samples. However, due to the large demand for samples, some single inspection items even require the preparation of at least 1kg of melon seeds. If all the processing is done manually, it will be time-consuming, labor-intensive, and inefficient. In addition, most laboratories have heavy sampling tasks and tight human resources, and manual shelling has caused a great burden on the sample preparation stage. In particular, microbiological inspection projects have very high requirements for sample processing, and exogenous contamination must not be introduced. Therefore, food inspection and testing laboratories are in urgent need of suitable equipment for melon seed shelling.
[0004] The melon seed shelling devices in the prior art are usually large in size, occupy a large area, and require too much production input each time, so they are generally only suitable for use in food processing companies. There are also a small number of melon seed shelling devices designed for home use, but the processing capacity of such melon seed shelling devices is too small, and the inside of the device cannot be cleaned or is very difficult to clean, which has the risk of introducing exogenous contamination and is prone to cross-contamination between samples. Therefore, they are not suitable for the preparation of melon seed samples in the laboratory. Summary of the invention
