The experts conducted a detailed consultation and interviews. Now introduce several new feed drying equipment and methods for your reference.

1. The purpose and method of feed drying
The purpose of feed drying is to remove the excess moisture in the feed material for packaging, transportation, storage, processing and use. Drying equipment classification, drying equipment, according to the different classification, commonly used drying equipment: spray drying equipment, fluidized bed drying equipment, air drying equipment, rotary cylinder drying equipment, drum drying equipment, infrared drying equipment, high Frequency drying equipment.

2. Emerging drying equipment 
(1) spiral flash drying equipment Spiral flash drying equipment mainly by the feeder, drying room, cyclone separator and bag collector composition. The dried material enters the drying chamber from the feeder, the hot air enters the drying chamber along the tangential direction and flows upward from the bottom of the drying chamber at a high speed, and makes full contact with the material so that the material is in a stable balanced fluidization state. In the drying chamber, , The mass of material is dispersed into irregular granules and the larger un-dried material moves toward the wall of the chamber and falls to the lower portion of the drying chamber due to its large settling velocity, repeating the above- process. As the materials are dispersed and the materials are collided with each other, the dry particles on the surface of the material block will move to the axis of the drying room gas rotation axis and be discharged to the material collector together with the airflow, so as to obtain the drying with uniform particle size and dryness. product. This drying equipment has the outstanding advantages of high drying efficiency, low energy consumption, uniform drying products, compact structure, will crush and dry in one melt. Apply to dry and sticky, paste, powder, cake-like materials. In the feed industry, can be used for drying blood meal, meat and bone meal, fish meal, protein cream, dross and so on.

(2) spiral vibration drying equipment The machine from the inside and outside the tube, ring orifice, vibration source and other components. Two vibration motor cross arrangement, the motor rotation, will produce vertical excitation force and the vertical axis of the excitation force even moments, so that the vertical and vertical drying equipment body vertical vibration and vertical centerline around the torsional vibration , The synthesis of two vibrations, the material along the horizontal annular orifice from top to bottom to do continuous jumping movement. The drying medium from the blower through the air inlet into the drying tube, bottom-up through the layers of the orifice, through the material layer. As the material continuously throwing, flip, both to avoid the material adhesion spiral groove surface, but also greatly increases the material and drying medium contact area, thereby strengthening the material and drying medium heat and mass transfer process. The advantages of spiral vibration drying equipment is energy-saving, suitable for a wide range of materials, dry product quality, high production efficiency. Suitable for drying all kinds of granular, powder, block, sheet materials. In the feed industry, the drying equipment can be used for drying fish and shrimp bait, a variety of additives, distiller's grains, starch residue, plant protein.

(3) rotary vane drying equipment Rotary vane drying equipment is downstream-type drying equipment. The material is fed into the rotary drum by the feeding device, and the material plate is put in the cylinder to lift the material to the top. When the material is falling, the high-speed rotating blades are broken, so that the material moves to the outlet and, at the same time, Hot air generated by the combustion furnace into the tube with full access to the material, so that the material quickly dried, and then discharged through the discharge side of the conveyor. As the drying equipment built-in broken leaves, can make the material into the drying equipment immediately broken up, in particular, there is a certain viscosity of the material from the large pieces were broken into small pieces, bring out part of the water, so that with hot air full Contact, speed up the drying rate. The drying equipment is characterized by large heat transfer coefficient, high thermal efficiency, product deterioration, oxidation, processing capacity. For drying a variety of granular, small block, sheet-like high-humidity materials. In the feed industry, the machine can be used to dry chicken pig manure, forage, such as bad residue.
