Detail

OneProduct Description:

The laboratory micro spray granulator (micro boiling granulator) is a miniature multi-function granulating and coating equipment developed by our company. It has the advantages of small volume, low material handling capacity and convenient preparation, and can be used for mixing, drying, granulation and coating functions of various pellets and pellets. The equipment also has spray drying function to meet the needs of universities and scientific research. There are nearly more than 500 institutions of higher learning in our country that have adopted the spray granulation equipment of our company.


TwoProduct mix:

The multi-function spray granulation machine top spray device is made up of a conical pot body and expansion chamber. Because the pot body is cone-shaped, the fountain type fluidization state is ensured, and the inlet air flow drives the material in the pot to enter the expansion chamber upward. The gravity is greater than that of the wind, and the material moves back and forth in the pan and the expansion chamber. A plurality of nozzles are installed at the top of the expansion chamber, which can be used for spraying atomized liquid into the granulation and coating process. Top injection can be applied to many aspects such as drying, granulation and masking.
The bottom spraying device of a multi-function spray granulator is composed of a conical pot body and a built-in draft tube. The bottom of the pot body adopts a double air inlet structure to control the flow state inside and outside the draft tube. The material moves upwards at high speed in the draft tube and enters the expansion chamber and falls into the outside of the draft tube. The atomizing spray gun is installed in the center of the diversion tube. The spray gun sprays liquid from bottom to top, and the direction is consistent with the direction of material and air flow. Bottom spraying is mainly used for functional coating of pellets and fines.


ThreeTechnical characteristics:

1) the multi-function spray granulation machine is easy to operate: the control system adopts PLC automatic control, and the color touch-screen operation. The experimental parameters such as inlet air temperature, air temperature, material temperature, fan speed and spray pressure during the experiment can be changed immediately according to the experimental needs and convenient for users. The touchscreen has USB interface and data can be used. Export to U disk or print online;
2) Operation stability: the core components of the equipment, such as touch screen, fan, heater and control system are imported equipment to ensure the stability and reliability of equipment operation;
3) the multifunctional spray granulator can replace the pan with different volume to meet the experimental needs of different batch materials.
4) feedback function of material temperature and inlet air temperature to ensure the realization of the best process.
5) the multi-function spray granulator adopts a new blow back system to effectively improve the granulation yield.
6) in order to meet the requirements of users in adjusting the parameters in the experimental range, the multi-function spray granulation machine adopts real-time control PID constant temperature control technology in the design of temperature control, so that the temperature control in the whole temperature zone is accurate, and the temperature is stable in the process of granulation and coating.


FourSummary of working principles:

Spray agglomeration in fluidized beds is a molding method that can enhance the properties of powders. By spraying in a fluidized bed system, we can transform the powder, non fluidity, and generally poorly soluble particles into free flowing large particles with excellent solubility. The method is especially suitable for the preparation of tablets and the manufacture of detergents, drinking powders and instant products.

Fluidized bed spray agglomeration and granulating can move tiny powder particles on the fluidized bed, and spray them to bind solution or suspension to produce liquid bridges to form aggregates. Continue spraying until the aggregate reaches the required size. When the capillary and the residual water on the surface evaporate, a hollow space is formed in the particles, and the hardened adhesive solidifies the new structure completely. The lack of kinetic energy in the fluidized bed results in extremely porous structures, which contain a large number of capillaries. Aggregates usually have a size ranging from 100 microns to 3 millimeters, while the starting materials can be super finely sized.

Efficient solution for fluidized bed drying and granular controlled drying (multi-function spray granulator)

Fluidized bed drying is the best way to control wet, powdered, controlled, soft and uniform drying. The intense heat / mass exchange of fluidized bed products makes this method particularly efficient and time-saving. The technology is also suitable for post drying of residual plastic products with low moisture content and extrusion products.

Fluidized bed drying can be used in the whole powder processing industry. In the pharmaceutical industry, this innovative approach has long replaced time-consuming tray drying: drying in a fluidized bed drying process can reduce drying time in a drying oven by about 20 times. In addition, compared with uneven tray drying, fluidized bed drying can provide controlled and uniform drying conditions.

Whether the product is produced in a fluidized bed or a high shear mixer, whether it is mass production or continuous production: drying through a fluidized bed must ensure that drying is always carried out in a thermodynamic equilibrium. The inlet temperature must be chosen so that water transferred from the inside of the particle to the surface through a capillary tube can just evaporate from the surface of the particle. If the inlet temperature is too high, it is likely to form a surface crust, which prevents or even prevents water from being transported deeper into the outside. This will slow down the whole drying process, not speed up.

For spray granulation, spray agglomeration or spray process, it should be noted that not only the moisture needs to be evaporated until the defined residual value is reached, but also the drying process is carried out throughout the spraying process. Too high intake temperature may lead to insufficient liquid bridge, unstable granular structure and uneven appearance.

Fluidized bed drying can provide an efficient solution under reasonable use, bringing soft and uniform drying to your products.


FiveGranulation principle:
The coating principle of multi-function one step granulator for spray granulation coating machine: the bottom spraying device is an important breakthrough in coating technology, making it possible to coat small particle materials. With the development of technology, it has been possible to coat powders of up to 50 m. The bottom spraying device is composed of a conical boiler body and a draft tube. The bottom of the boiler body adopts a double air inlet structure to control the air flow inside and outside the draft tube. The material moves upwards at high speed in the draft tube and enters the expansion chamber and falls into the outside of the draft tube. The spray head atomized droplets from top to bottom in the center of the draft tube, and the droplets spread evenly on the surface of the particles to form a small film. During this process, the thickness of the coating film increased steadily and dried to the completion of the coating.
