Circular vibratory screen machine from inside and outside the tube, the annular diaphragms, vibration source. Two vibratory screen motors cross arranged, perpendicular to the direction of rotation of the motor will produce exciting force and a couple of exciting moments around the vertical axis of the rotary vane linear vibratory screen machine are downstream.
So that the circular vibratory screen sieve linear vibratory screen and do the vertical direction around the vertical centerline torsional vibration, two vibration synthesis, so that the top of a material along the horizontal annular diaphragms do continuous jumping movement. Drying medium by the blower through the air inlet blown into the drying cylinder, the bottom-up through the layers of the orifice plate, through the material layer. Material throw, flip, we can avoid material the adhesive spiral groove surface, but also greatly increase the contact area of the material and drying medium, thereby strengthening the material and drying medium heat transfer, mass transfer process. If the temperature was kept constant while reducing the pressure, will get the same result. The vacuum freeze-drying is based on the water of this nature, the use of refrigeration equipment, the material to freeze into a solid, and pulls a vacuum so that the solid ice sublimates directly into the gaseous water vapor, so as to achieve the purpose of drying. Freeze-drying has many advantages: low pressure, the material is not easy to oxidative deterioration, suppress some of the vitality of cells.
The advantages of the vibratory screen station is energy saving, wide range of applicable materials, dry product quality, high production efficiency, suitable for drying various granular, powdered, lump, flake materials. In the feed industry, the circular vibratory screen can be used for a variety of additives, distiller's grain, starch residue, vegetable protein, etc.. Due to the vibratory screen sieve built crushing blade can enter vibratory screen sieve material within Claim been broken, in particular there is a certain viscous material from the large clumps are broken into small pieces, and in contact with hot air, with a portion of water to make adequate contact with the hot air to accelerate the drying speed. The characteristics of the linear shaker is the heat transfer coefficient, high thermal efficiency, product oxidative deterioration, large capacity, suitable for drying various kinds of granular, small block, flaky humidity materials.
