[0003] The helical blades of the auger of the device spirally extend to the bottom of the tank body along the conical surface of the cone body. When working, the helical blades of the auger scrape up the granular materials at the bottom of the tank body and transport them to the upper side of the tank body to be mixed with the atomized liquid droplets. Contact, but its disadvantages are: the inner wall of the spiral casing and the internal spiral blades are cleaning dead angles, which cannot be cleaned by compressed air or manually, and the added oil is atomized and sprayed, and will be bonded to the spiral with the powder in the material; After spraying the material many times, the inside of the tank is not cleaned cleanly, and bacteria are easy to breed, which makes it impossible to meet the requirements of food hygiene; the conical discharge door is easy to stick to the material, resulting in poor closure and the risk of air leakage; the single auger cannot fully stir the material , the spraying is not uniform enough, the internal volume of the tank is not large enough, and the efficiency of spraying and processing materials is low

Abstract

The invention discloses an automatic vacuum spraying process method in the field of food, pet food and aquatic feed processing. The automatic vacuum spraying process method comprises the following steps: self-inspection: carrying out self-inspection resetting on a weighing sensor of material adding equipment; feeding: adding material particles into a mixing cavity through a feeding port; vacuumizing: opening a butterfly valve connected with a vacuumizing pipe, starting a vacuum pump, and vacuumizing the interior of the mixing cavity; spraying: spraying grease to the material particles in the mixing cavity through a first nozzle assembly; vacuum release: enabling air to enter the mixing cavity by adjusting the opening degree of a pressure release valve; normal-pressure slurry spray/powderspraying: spraying a pasty phagostimulant on the surfaces of the material particles in the mixing cavity through a second nozzle assembly, or adding a powdery phagostimulant into the mixing cavity through the feeding port; discharging: continuously rotating the stirring shaft, opening a discharge door, and discharging; and continuing self-inspection and feeding, and starting the next cycle. Vacuumspraying can be completed quickly and efficiently, and the spraying efficiency is higher.
