50% powder chloride drying process

LIMA Fish Feed Machine,Chicken Feed Machine

Choline choride chemical name is 2-hydroxyethyl-trimethyllamine hydrochloride, the molecular formula is C5H14ClNO, and the molecular weight is 139.63. The structure of chloride choline is shown in Figure 1.
Chloride is divided into two states of liquid and powder. This paper studies the drying process of a 50% carrier-type powder chloride (from 70% choline solution with bran, corn core, and bronchi), which is mixed after drying. Carrier bran, corn core, bull skin contains starch and protein colloid, such materials expand the starch particles after impregnating the chloride aqueous solution, and the swells encounter 60 to 80 ¡ã C during the drying process Paste the material, resulting in bonding blocks; the protein colloid occurs gel at this temperature due to its hydrophilic effect, and also causes the bonding of materials. The synergistic effect of starch and protein colloids sometimes makes the drying material plate into a plastic block that cannot be pulverized, damages the production equipment, and makes production cannot be carried out. How to avoid gelation of starch and how to avoid protein gelation or destroy its gelation, is the key to selecting a dry process condition.
1 Domestic powder chloride drying production process and its existing problems
1.1 1980s, manufacturers generally use ovens or drying room drying, materials often slammed, after crushing, can not guarantee Product quality; material is vague variability, even combustion, bringing great problems to safety production. The drying system has a small single-machine processing, and does not meet the requirements of large-scale production. The production environment is poor, and the labor intensity of workers is also large.
1. Drying powder with fried pots, high energy consumption, small production, poor labor conditions, and high labor intensity are high.
1. Tube bundle dryer dry powder chloride, during drying, the material is easily adhered to the outer wall of the heat transfer tube, resulting in a metamorphization of the material, and the product quality is not good. Single-machine processing amount of drying system does not meet the requirements of large-scale production. The typical process is shown in Figure 2.
1. Dry powder, dry powder, drying process, dry process, gas flow pipe, is easy to stick, fire, causing safety accidents. The cyclone is easy to stick to the wall, the system is difficult to run longer, the single-machine processing is small, and the requirements for large-scale production cannot be met. Its typical process is shown in Figure 3.

1.5 Crushed swirl dryer dry powder chloride, the material in the airflow tube is easy to stick to the air during the drying process, causing safety accidents. The drying system has a small single-machine processing, and does not meet the requirements of large-scale production. The swirl dryer is easy to stick to the wall, and the system is difficult to run longer. Its typical process is shown in Figure 4.

1.6 Rotating flash dryer dry powder chloride, and the equipment is small. The material is easy to stick to the wall, accumulating the cone portion of the flash dryer, causing the equipment to be normalWork. Its typical process is shown in Figure 5.
1.7 Rain drying machine drying powder cholinergic, and the amount of equipment is small. The material is easy to stick to the wall, accumulating at the top of the dryer, resulting in a substantial deterioration, and even fire burning. The typical process is shown in Figure 6.
1.8 Fluidized bed dryer dry powder chloride chloride, most of the single-machine yield can operate below 500 kg / h. The drying system is small, and the requirements for large-scale production are not met, and the wind board of the fluidized bed and the particulate material in the bed are required to be cleaned up. During the drying process, the material is easy to pick up the ball and cake, and it needs to be broken after drying. Its typical process is shown in Figure 7.
2 Determination of the drying process
The above powder chloride drying process, and there is a disadvantage that the treatment amount is small, high reliability, and high energy consumption. After the technical and economic comparison of various drying methods and an overview of a large number of documentary data were determined, 50% powder chloride was determined using a secondary self-cleaning rotary cylinder drying machine. Its typical process flow is shown in Figure 8.
The production process has been successfully applied to several chloride drying works in China. The indicators of long-term production practices are as follows: 1 Product annual output gt; 10,000 tons; 2 powder chloride choline drying water 25%; 3 powder choline dry after drying 0.97%; 4 drying machine The rotation speed of 3 r / min; 5 air temperature 160 ¡ã C; 6 exhaust temperature 80 ¡ã C; 7 system steam energy consumption of each ton product ¡Ü 0.92 t.
3 Conclusion The choline production process has the following advantages.
1 solves the problem of material deterioration caused by choline choline in the drying process, and even the problem of fire, the safety and reliability of the system has been greatly improved.
2 Solved the quality of product quality that cannot be guaranteed due to the adhesion of materials, the quality of the product reaches the international level.
3 The entire production process material is basically operated in a closed state, making the pollution problem of odor flavor greatly improve.
4 The energy consumption of the system is greatly reduced, saving costs.
