PGL Series Spray Dryer Granulator
Description：The working process of this unit is that the feed liquid passes through the high pressure input of the diaphragm pump, sprays droplets of mist, and then flows down in parallel with the hot air. Most of the powder is collected by the bottom discharge outlet, and the exhaust gas and its tiny powder are transported by the cyclone. The separator is separated and the exhaust gas is discharged by the exhaust fan. The powder is collected by a pollination cylinder located at the lower end of the cyclone separator. The fan outlet can also be equipped with a secondary dust removal device, and the recovery rate is above 96-98%.
Details
Product Overview
This unit is a device that can complete drying and pelletizing at the same time. According to the process requirements, the pressure, flow rate, and size of the orifices of the feed pump can be adjusted to obtain the desired spherical particles in a certain size ratio.
The working process of the unit is that the feed liquid passes through the high pressure input of the diaphragm pump and sprays droplets of mist, which then flow down in parallel with the hot air. Most of the particles are collected at the bottom of the tower and the exhaust gas and its tiny powder are separated by a cyclone separator. The exhaust gas is discharged by the exhaust fan. The powder is collected by a pollination cylinder 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 96-98%.
The material of the tower body, pipelines, and separators that are in contact with the material of this unit is made of SUS304. There is a sufficient moisture-retaining layer between the inside of the tower body and the shell, and the filling material is ultra-fine glass wool. The tower body is provided with an observation door, a sight glass, a light source and a control instrument, which are controlled and displayed by an electric control console.
Product Application
Pharmaceutical Industry: tablets, granules, capsules; low-sugar, sugar-free proprietary Chinese medicine granules; food: cocoa, coffee, milk powder, granular juices, seasonings, etc.; other industries: pesticides, feed, fertilizers, pigments, dyes Wait.
Product features
1. Drying speed is fast, the surface area of material liquid is greatly increased after atomization, and 95%-98% of water can be evaporated instantaneously in the hot air current. The drying time only needs ten seconds to several tens of seconds. It is especially suitable for the drying of heat sensitive materials.
2. All products are spherical particles, uniform particle size, good fluidity, good solubility, high product purity, and good quality.
3, the use of a wide range, according to the characteristics of the material, you can use hot air drying, you can also use cold air granulation, the adaptability of the material.
4, the operation is simple and stable, easy to control, easy to implement automated operations.
1. Control cabinet 2, infusion trolley 3, host 4, heat exchanger 5, sub-high efficiency filter 6, muffler 7, induced draft fan

Selection example: Each batch of treatment liquid extract amount I = 120kg (solid content is 30%), seed quantity II = 60kg, theoretical yield can be derived from I, II M = mI + mII = 120kgx30% +60kg = 96kg, working time T = 120kg/30kg/h = 4h, the boiling point can be found in the technical parameter column as the standard load range, so it is more appropriate to use the PGL-30 type to complete two batches per shift.
