Description

Technical Field

[0001] The utility model belongs to the field of coconut flakes processing and production equipment, and particularly relates to a device for automatically rehydrating, embrittlement and cleaning compressed coconut flakes. Background Art

[0002] The current coconut natto processing process involves the following steps: First, the compressed coconut natto is rehydrated several times until it is plump. This process is repeated four to five times to ensure that the pH is adjusted to the 5-6 range and the specified size standards are met. During this process, the purified water must be frequently replaced manually. After the rehydration step, the coconut natto is drained and transferred to the embrittlement stage. This involves adding an embrittlement solution and heating it to a boil, maintaining a slight boil for 15-30 minutes. It is then packaged and sterilized.

[0003] During small-scale production in a laboratory setting, limited equipment availability necessitates manual operation of all rehydration and embrittlement steps, one by one. In contrast, workshop production lines are more suitable for large-scale production, but product stability is difficult to guarantee for small batches. Key issues with the current coconut processing process include frequent rehydration, long processing times, high water consumption, and a lack of continuity between production steps.
