Description

TECHNICAL FIELD

[0001] The utility model relates to the field of food vinegar production, and specifically discloses a food vinegar production post-maturation device with good mixing effect. BACKGROUND

[0002] Food vinegar post-maturation is a key process in food vinegar production, and through standing and slow oxidation, organic acids, esters and other flavor substances in vinegar are fully mixed. However, the prior art has the following significant defects in practical application:

[0003] Conventional stirring devices (such as single-shaft paddles) are prone to form flow dead zones during operation, leading to uneven distribution of dissolved oxygen in upper and lower layers of vinegar in the tank, significant differences in microbial metabolic activity, and insufficient esterification reaction in some areas with excessively high acidity, directly affecting the flavor levels of food vinegar.

[0004] Colloidal precipitates generated during post-maturation easily deposit at the bottom of the tank. Traditional conical tank bottoms can partially collect precipitates, but lack dynamic anti-accumulation structures and require frequent shutdown for cleaning. Meanwhile, fixed air vents cannot achieve uniform diffusion of gas-liquid microbubbles, resulting in low oxidation efficiency.

[0005] Food vinegar post-maturation requires consideration of both aerobic and anaerobic bacterial activity. Existing devices have poor sealing (such as open structure of ceramic jars prone to contamination) or single function (such as lack of temperature control integration in stainless steel tanks), which cannot precisely adjust the micro-oxygen environment and temperature gradient, leading to prolonged post-maturation period and unstable quality.
