LQZ series spray cooling granulator

product description

LPZ-type centrifugal spray cooling granulation device is practical and highly targeted products, is my company for low melting point material cooling granulation "tailored" well-designed special equipment.
Technical characteristics
● Specially designed eddy current air distributor, based on the basic principles of aerodynamics and fluid dynamics, intensifies the heat and mass exchange between the cold air and the hot melt droplets, and at the same time, the system uses the inverse-parallel flow mode to ensure the hot melt fog Drops are fully and effectively cooled by cold air to complete the cooling granulation process.
● The prilling tower adopts the jacketed air-cooling device to ensure the "hot-melt wall" phenomenon of the material does not occur on the inner wall of the prilling tower.
● patented "low hat" exhaust structure device to ensure that more than 90% of the finished product collected in the bottom of the granulation tower, only a small amount of powder into the cyclone, reducing the cyclone gas-solid separation pressure.
● Into the prilling tower system, all of the air through the early, middle and sub-efficient three-stage filtration, purification level reached 300,000 or more.
● The inner wall of prilling tower, powder pipeline and cyclone material are made of stainless steel SUS304 / BA mirror plate. The welding seam is all protected by argon gas and the weld is polished and polished with the precision of 0.3μ, effectively preventing the pipeline " Accumulation powder accumulation "phenomenon. The outlet pipe and the cyclone separator are equipped with quick-opening washing ports for disassembling, cleaning, disinfecting and sterilizing, which fully meets the requirements of food hygiene.
● Product recovery system equipped with a special secondary fluidized bed cooling and drying device to complete the spray granulation of the powder to be sub-cooled and then dried, fully cooled and dried finished product good fluidity, low temperature, can be directly packaged.
Application range
Fat powder, palm oil, amino fatty acids, paraffin, glyceryl fat, tallow, etc., food additives, plastic additives.
Introduction Design a: (according to the material properties and parameters)
Cooling spray granulator (microspherical)
This equipment is mainly used for the spray cooling pelletizing of melting chemical materials such as polyethylene grease, paraffin wax, amino fat, glycerol acid ester and rubber plastic additives to meet various requirements of customers on the product particle size.
Spray Cooling Products During spray cooling / spray condensation, the melt is sprayed into the cooling tower to form spherical particles.
Spray cooling
Cooling process by the introduction of sufficient low-temperature air to complete. The melt is atomized or pelletized by a rotary atomizer fitted with a specially designed rotor, optionally with a pressure nozzle or dual flow nozzle. Spray cooling, used in the chemical, food and pharmaceutical industries, is a suitable method of processing molten material into free-flowing particles and controlling particle size.
Melt characteristics
When the melt atomized droplets come into contact with the cooling air, they can be cooled to a solidified state. The condensation of the pure substance takes place at a constant temperature which is formed during the release of the curing heat by the product.
Not all melts have a defined freezing point. Phase changes can occur over a range of temperatures, or they can be released from the melt phase to the amorphous solid, because of the non-crystalline structure. Atomized droplets may also be subcooled below the solidification temperature.
It is important to state the physical properties and the cure properties of the melt with the data. Based on this, we determine the size and size of the cooling tower, the method of atomization, and the mode of co-flow or counter-flow of gas selected during cooling. In some cases, two-stage cooling method can show advantages.
Spray cooling products
Capsule products

Glycerides
Hydrate
Inorganic / organic melt
Quaternary ammonium compounds
Fatty acids, waxes, magnesium stearate
Design selected
Use of ambient air cooling fluidized bed cooling device is most suitable for two-stage cooling, air conveying system can also be used with cold air delivery.
Design selection also based on the finished product particle size requirements, from fine particles, coarse particles to extra coarse particles, coarse particles to extra coarse products.
Optimize cooling energy consumption and product quality
Equipment that operates in warm climates may require dehumidification and cooling of air before entering the spray cooler. To reduce additional energy consumption, the process air is typically recycled to minimize the load on the dehumidification and cooling equipment.
The recirculation system is designed to allow the evolution of gas from the system and the introduction of ambient air with some degree of vaporization accompanied by spray cooling. The multi-way damper installed in this circulation system allows the equipment to operate in an open cycle without the need to start the dehumidification and cooling equipment, thus reducing operating costs in a cold and dry season.
Run the equipment
Introduction Design two: (according to the particularity of the material parameters)
Granulation drying is a widely used technique for liquid melts. The most suitable melt and plasticity lake-like liquid waxy solid, granular or spherical solid products. Therefore, the final particle size distribution, residual moisture content, bulk density and particle shape must meet the exact standards. Granulation drying is a very good technology. The company is located in:
principle:
The air is filtered by the air surface cooling, into the dryer top air distributor, the hot air spirally into the granulation tower. Liquid feed through the granulation atomizer at the top of the tower, atomized into liquid beads, the tower body to form downstream flow and counter-flow in the formation of mixed flow, increase heat transfer efficiency, and cold air cocurrent contact in a very short period of time can be cured dry For the finished product. The finished product is continuously output from the bottom of the drying tower and the cyclone, and the exhaust gas is exhausted by the fan.
Features:
The cooling speed is high, the surface area of the molten material greatly increases after atomization, and in the cold air current, 70% -80% of the heat can be instantly evaporated, and the drying time is only required for a few seconds. The product has good uniformity, fluidity and solubility Product purity, good quality.
Simplify the production process, easy operation and control. 40-80 mesh for special materials yield of 85%, 30-80 mesh yield of up to 95% can be dried into a microcapsule products, no need to screen after drying to reduce the production process and improve product purity. The product particle size, bulk density, moisture, within a certain range can be adjusted by changing the operating conditions, control and management are very convenient.
Uses: plastic additives, food additives, chemical additives, stearic acid, monoglyceride, paraffin and other solids.
