This unit is a device that can simultaneously complete drying and granulation. According to the process requirements, the pressure, flow rate, and nozzle size of the material liquid pump can be adjusted to obtain the required spherical particles in a certain size ratio.
The working process of this unit involves the high-pressure input of material liquid through a diaphragm pump, spraying mist like droplets, and then flowing down in parallel with hot air. Most of the powder particles are collected by the bottom discharge port of the tower, and the exhaust gas and its small powder are separated by a cyclone separator. The exhaust gas is discharged by a suction fan, and the powder is collected by a pollination tube located at the lower end of the cyclone separator. The fan outlet can also be equipped with a secondary dust removal device, with a recovery rate of over 96-98%.
The tower body, pipeline, and separator materials in contact with the materials of this unit are all made of SUS304. There is sufficient moisture retention layer between the interior of the tower and the outer shell, and the filling material is ultra-fine glass wool. The tower is equipped with observation doors, mirrors, light sources, and control instruments, which are controlled and displayed by an electrical control console.
Product application
Pharmaceutical industry: tablets, granules, capsules and granules; Low sugar, sugar free traditional Chinese patent medicines and simple preparations granules; Food: cocoa, coffee, milk powder, granular fruit juice, seasonings, etc; Other industries: pesticides, feed, fertilizers, pigments, dyes, etc.
Product Features
1. The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% -98% of the water can be evaporated in an instant, and the drying time only needs tens of seconds to tens of seconds. It is particularly suitable for drying heat sensitive materials.
2. All products are spherical particles with uniform particle size, good flowability, good solubility, high product purity, and good quality.
3. Widely applicable, according to the characteristics of the material, it can be dried with hot air or granulated with cold air, with strong adaptability to the material.
4. Simple and stable operation, convenient control, and easy implementation of automated tasks.

Technical parameter
Selection example: It is required to process a liquid extract amount of I=120kg (with a solid content of 30%) and a seed amount of II=60kg per batch. The theoretical finished product amount M=mI+mII=120kg x 30%+60kg=96kg can be obtained from I and II. The working time T=120kg/30kg/h=4h. The boiling amount can be found in the technical parameter column as the standard load range. Therefore, PGL-30 type is more suitable for completing two batches per shift.
