Vacuum spraying equipment technological advantages
Spray pet food, fish feed and other products, suitable for production lines with high-fat content feed, batch spraying and seasoning mixing. The obvious advantages of vacuum spraying are that the liquid addition ratio can reach up to 30%, and the accuracy and uniformity of liquid spraying are high
Compared to atmospheric pressure spraying, vacuum spraying has technological advantages
Firstly, it can accommodate larger amounts of additives, such as up to 36% oil and fat additives. At present, the amount of oil added to the popular California bass in China needs to reach 9-10%, which cannot be achieved by using atmospheric pressure spraying.
Secondly, the vacuum spraying process is not limited by the amount of liquid added or viscosity, and can be sprayed in stages, even effectively utilizing the characteristics of different liquids to form complementarity.
Thirdly, nothing oil addition before ultrafine grinding can increase the production capacity of ultrafine crushers by 15%, greatly enhancing the production capacity of the production line.
Fourthly, zero addition of oil before puffing can improve the flexibility of the formula and improve the material type without sacrificing production capacity. On the contrary, it can increase the production capacity of the puffing machine by 20%.
Fifthly, increasing the fat level (digestible energy level) in the feed can improve the storage rate of digestible protein and reduce formula costs.
