A vacuum oil spraying device for fish feed

ActiveCN224268222UGuaranteed nutritionNot easy to spreadFeeding-stuffFood coatingOil and greaseNutrition
This utility model relates to an oil spraying device, specifically a vacuum oil spraying device for aquatic feed. The device includes a vacuum tank, to which a vacuum pump is connected via a vacuum tube. The vacuum tube has a venting opening. A feeding mechanism is located at the top of the vacuum tank, and an oil spraying mechanism is located below it. This device sprays oil onto the feed surface. After spraying, the atmospheric pressure from the vacuum venting forces the oil adsorbed on the feed surface into the feed pores, forcing the oil into the feed interior. This prevents the oil from diffusing to the water surface, eliminating the barrier of air created by the oil and allowing effective contact between air and the water surface, thus effectively increasing dissolved oxygen levels. Simultaneously, it prevents nutrient loss due to oil diffusion, effectively ensuring the feed's nutritional value. This solves the problem of existing oil spraying devices only spraying oil onto the feed surface, causing the oil to easily diffuse to the water surface, resulting in the oil isolating the water from air and leading to nutrient loss.
