Description

Technical Field

[0001] The invention relates to the technical field of minced fish production, in particular to automatic water adding equipment and method for minced fish production. Background Art

[0002] In the production of surimi products, surimi is the core raw material, and its quality is directly related to the quality of the final product. In the traditional surimi production process, it is difficult to control the amount of water added during the mixing process of surimi and water.

[0003] In the past, workers relied on their experience to roughly judge whether water was needed by observing the appearance of the surimi with the naked eye or simply touching it with their hands. This subjective judgment method has great errors. Due to the lack of accurate detection methods, it is impossible to grasp the exact water content of the surimi in real time. Once too much water is added, the excess water will seep out during the subsequent processing, affecting the product molding, and may also breed microorganisms and shorten the shelf life of the product; if too little water is added, the surimi will not be sticky enough and difficult to process and shape, which will also reduce the product quality.

[0004] With the increasing quality requirements of consumers for surimi products and the demand for large-scale and standardized production in the food industry, it is necessary to provide an automatic water-adding equipment for surimi production and a method for adding water to surimi to meet the demand for accurate addition of water during the mixing and processing of surimi.
