(For dry granules of size 1 To 3 mm, depends on type of product and sieve size.)

Granulation:
Mechanical process in which the product is crushed and pressed through a sieve with a specially shaped rotor to obtain a desired particle size. This process results in a narrow distribution spectrum as only the product having the right shape & size is passed through the sieve.

Oscillating rotor:
The oscillating motion of the rotor improves the granulating process. This sensitive handling of the product emulates the hand operation of an experienced pharmacist.

One important feature of the Oscillating Granulator is the continuous variation of the speed and force applied to the material. The back and forth motion of the rotor results in an even distribution of the material and also reduces fine particle generation.

Sruti offers perforated sheet sieves with perforation sizes ranging from 0.5 mm to 10 mm

The spraying system used for atomized film coating of tablet on conventional coating in pharmaceuticals food, Agro chemical and confectionery industries.

The spraying system is consists of Atomized spray nozzle, High Precise Peristaltic pump, Stand for Gun, Solution holding tank and automatic controls system. The complete system is work on based on auto coater machine technology for film coating.

In the past two decades, functional coating of small particles such as granules, pellets and mini-tablets has become an integral part of pharmaceutical development and production. However, the coating process introduced challenges concerning IPC and weight gain. Researchers typically work with theoretically calculated weight gain as well as trial and error experiments, supported by PSD measurements.

The traditional solution to this challenge derived from the tablet coating process, where tablets are usually counted in batches of 100 tablets, with repeated weighing during the process. The calculated average weight of one tablet shows when the target weight gain is reached.

But when particles had to be counted, the same procedure was impossible to follow due to the need to count thousands of particles.

The innovative solution to this problem came from DATAs Pellet Counter, which allows users to count large amounts of particles.

Oscillating Granulator is used for gentle homogenization, size reduction, grading and sieving of dry, sensitive powders and granules in pharmaceutical, chemical and food industries.

Oscillating Granulator has one rotor with five edges, which oscillate on horizontal axis at about 180 per minutes. There is one half round sieve mounted at the bottom of the rotor. Product is charged from the top through in feed hopper and material falls on the rotor lades. The particles are broken by a set of oscillating bars arranged in cylindrical form over a screen of suitable mesh. Due to the sharp edges on rotor, the downsizing of particle takes place and through sieve material gets pushed outward from the bottom opening.

A colloid mill is a machine that is used to reduce the particle size of a solid in suspension in a liquid, or to reduce the droplet size of a liquid suspended in another liquid. This is done by applying high levels of hydraulic shear to the process liquid. It is frequently used to increase the stability of suspensions and emulsions. The colloid mill is used for various applications such as Superfine grinding, homogenizing, emulsifying, dispersing, mixing and extracting of liquids, ointments and highly viscous products in pharmaceutical, cosmetics, suspensions & emulsion industry.

The product is fed to the hopper which leads the product into the gap between rotor and stator. The product is subjected to a high degree of shearing, cutting and rubbing between two metal toothed surfaces of rotor and stator and towards the discharge section. The processed product continuously leaves the mill through drain pipe if required, it can be re-circulated by three way cock and re-circulating pipe assembly.

Fluid Bed Processing involves fast drying, cooling and agglomeration of particulate materials. It is ideal for heat sensitive and non heat sensitive products in Pharmaceuticals, Chemicals and Biochemical, Food and Dairy Industries.

The Fluid Bed Dryer have a bed of solid particles which are fluidized by passing a stream of air upward through a specially designed perforated sheet. The upward velocity of air is so maintained so as to slightly lift the solid particles and set them in motion. This motion can be utilized to bring about mixing as well as forward movement of the solids particles. The air is heated and the process hot air evaporates the fluid and dries the solids. Fines get agglomerated to larger granules particles thus providing large size

The machine is designed with correct volume of bowl, air velocity, direction and the temperature of the clean inlet air is maintained throughout the fluidization, retarding and expansion chambers, filtration area, pitch of the perforations of the plate at the bottom of product container, the leak-proof fluidization space by proper sealing, material of the filters and process controls with electrical & pneumatically.

The uniform drying is achieved by exposing the full surface of every particles of the solid mass to the incoming high velocity hot air.

Option for the process parameters are controlled by using latest PLC controls with HMI touch screen thus making equipment operationally safe and eliminating the possibility of human error. The process consistency with batch records is maintained for every batch every time.

The equipment can be inbuilt CIP system gives a thoroughly cleaned equipment for every batch eliminating contamination of subsequent batches.

Tray Drying Ovens are used for drying of pharmaceutical powders, granules, Pigments, Food, Bakery, Electrodes, Chemical, and Plastic, etc in an effective and economical way by hot air re-circulation.

Tray dryer is an enclosed insulated chamber in which trays are placed on top of each other. Heat transfer is done by circulation of hot air by electric heaters or any other heating media. Blower fans are installed inside to ensure proper circulation and transfer of heat.

Table top Laboratory Multi Mill is used for wet and dry granulation in pharmacy colleges, R&D institutions and pharmaceutical industry for research and development of pharmaceutical products.

It is a self contained portable unit useful for granulating, pulverizing, mixing and size reduction. The Multi mill operates on the principle of variable force swing beaters having both knife and impact edges rotating within a selected screen to get the required size reduction.

The material is fed in the hopper, shredded and milled through beaters consisting of knife and impact edges. The rotation speed and direction of beaters could be adjusted through control panel. The material then passes through the cylindrical screen in spiral motion which helps keeping the temperature low and avoids chocking of material during the process. The material is collected in the container placed under the hopper.

In multi mill particle size reduction is done through impact in air, on material by blades moving at high speeds, inside a cylindrical hopper.

The Laboratory Vibro Sifter, due to its high capacity and compact size, is suitable for processing small batch of pharmaceutical materials and in research of pharmacy colleges, research and development laboratories.

The machine is embedded with complete S.S. Fabrication structure fitted with Vibro motor and 12" Sieve and movable on 3 Nos. castor wheel for easy movability.

It is designed on the principle of 'Gyratory Motion". The material is fed on to the centre of the screen and then travels on a spiral path to the periphery whilst the fine particles fall through. The material being screened is therefore drawn apart automatically and no additional force is exerted to separate coarser particles. The sieving is done gently and with little abrasion.

High Shear Mixer Granulator is a multi purpose processor equally suitable for high speed dispersion of dry powder, aqueous or solvent granulations and effervescent products and melts pelletization.
