Description

Technical Field

[0001] This utility model relates to the field of vegetable washing equipment technology, specifically a high-efficiency vegetable washing device. Background Technology

[0002] In the food processing industry, vegetable cleaning is a crucial step in the production process, and its cleaning effect directly affects food safety, product quality, and subsequent processing efficiency.

[0003] Currently, the vegetable washing technologies commonly used in the food processing industry have the following main problems:

[0004] 1. Insufficient cleaning effect: Traditional cleaning equipment mostly relies on high-pressure spraying or drum friction cleaning. Although it can remove surface dirt, it is difficult to completely remove residual pesticides, microorganisms and mud and sand attached to the folds of vegetables, which cannot meet the high standards of hygiene and safety requirements of the food processing industry.

[0005] 2. High water consumption: Food processing enterprises usually need to wash vegetables continuously and in large quantities. Traditional equipment adopts unidirectional flow operation, which leads to serious waste of water resources. In addition, the direct discharge of sewage not only increases environmental pressure, but also increases production costs.

[0006] 3. Low efficiency of the filtration system: The existing equipment's filtration devices are mostly single-layer filter screens or simple sedimentation tanks, which are easily clogged by vegetable leaves, roots, etc., requiring frequent shutdowns for cleaning, which affects production efficiency. In addition, the lack of effective treatment for pollutants such as grease and colloids leads to a decline in the quality of circulating water and affects the cleaning effect.

[0007] Therefore, we propose a highly efficient vegetable washing device. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a highly efficient vegetable washing device with the following beneficial effects:

[0019] 1. This is a high-efficiency vegetable washing device. The washing tank of the vegetable washing machine consists of an inner box and an outer box, with a sandwich layer between the inner box and the outer box.

When the primary coarse filter layer and the intermediate adsorption layer work together, the pre-filtration of the primary layer can reduce the load on the intermediate adsorption layer (such as activated carbon or zeolite), preventing its microporous structure from becoming saturated quickly and extending its service life.
