Description

Technical Field

[0001] The invention relates to the field of longan kernel starch processing, and in particular to integrated longan kernel cleaning, drying, grinding and processing equipment and a method. Background Art

[0002] On April 4, 2023, South China Agricultural University submitted a patent application for longan kernel polyphenol starch active film, preparation method and use thereof. The patent application number is 202310353123.2, which is a prior application. This patent is for a deep processing device adapted for the deep processing of longan kernels, and has a certain relevance to the patent application.

[0003] Longan kernel is rich in starch and polyphenol compounds, and is a good renewable starch resource and source of functional active ingredients. Longan kernel starch can be used to prepare starch-based films.

[0004] It should be noted that the grinding equipment for major grains such as wheat is very mature, but it cannot be directly applied to longan kernels. The first reason is that the seed shapes are inconsistent, and the second reason is that the process requirements are inconsistent.

[0005] According to traditional design concepts, cleaning, drying, crushing and screening require four independent stations. Therefore, if the deep processing of longan kernels is transformed into productivity, a large amount of site environment and equipment are required, which is a relatively large investment. However, the output of longan kernels is definitely not comparable to the output of ordinary grains, so they are idle when not processed.

[0006] Lin Jing, Ye Shihua et al. published "Design and Practice of Disc-type Automatic Shelling and Core Removing Machine for Fresh Longan" in "China Equipment Engineering" on February 25, 2019; however, it only removes the core of longan, rather than deep processing of longan core;

[0007] A search was conducted in the Chinese Patent Publication Database using "longan kernel and processing and starch" as abstract keywords, with the search time node being 2023-05-01. The preparation of a longan kernel resistant starch disclosed in CN107501420A was not an equipment.

[0008] For industrialization, the continuous processing of longan kernel starch is a technical problem that needs to be solved urgently.

[0009] That is, the defects of the prior art are:

[0010] Excessive demand for workstations;

Pour the longan kernels in step 3 again through the guide funnel 24.

[0044] Step 5: Crushing:
