Fluid Bed Granulation Machine & Fluid Bed Pellet Coater Machine

Fluid Bed Granulation Machine & Fluid Bed Pellet Coater Machine

We are considered as the market leader when it comes to design the fluid bed drying machine, which also includes designing machines like the fluidized Bed Granulator Machine along with the Liquid Bed Pellet coating equipment as the FBD that we offer aids in the drying & cooling procedure used for heat-sensitive tablets and medicines with the help of reducing moisture of the tablet content within a specific period. Fluidized bed drying machine also plays a vital role in different industries like food, biochemical along with dairy product factories and pharmaceutical industries and every other industry where herbal manufacturing unit is required.
The granulation & pellet coating machine is specially designed in order to execute various coating operations on different types of granules & pellets that are used in various industries.


How Does Fluid Bed Dryer Work & What are Its Functions?

Shree Bhagwati Mechtech(India) Pvt. Ltd. is a leading manufacturer of the fluidized bed dryer. Fluidized bed dryer is an important part of pharmaceutical industries and is mainly used for the purpose of different processes like coating, cooling, agglomeration, coating, and drying including granulation of minute materials. Bhagwati Mechtech’s Fluid Bed Pellet Coater Machine is an excellent instrument for products sensitive as well as insensitive towards heat. It is utilized in a variety of industries due to its usability in various industries like Pharmaceuticals, Detergents, Nutraceuticals, Chemicals, Agrochemicals, Biochemical, Food, Herbals, Cosmetics, Biotech and various Pharma Institutes.

The fluid bed equipment can be categorized into different designs depending on the application as mentioned below:

1) Fluid Bed Drying & MixingProcess:

The Fluid Bed Granulator has a bedat the bottom of the instrument which contains minute particles which are passed to upper side through afluid. This fluidis further passed through perforated sheets which have been designed especially for this process. The velocity of air remains to an extent to move the particles to the upper portion and is again utilized for the movement of the particles to push forward towards the exit. Heated air is also passed through the particles to dry them by evaporating the moisture inside them. As a result fine particles are stuck together to larger particles which then end up as granules.

2) Fluid Bed Processor for Agglomeration and Granulation Processwith Top spraying System:

This process is utilized top form granules at the fluid bed from fine powder particles. The liquidated powder at the fluid bed uses materials such as binders or starch pest or a fluid. For performing the liquidation process the Fluid Bed Pellet Coater Machine uses a top spraying system installed with a nozzle for spraying and precise dosing peristaltic pump. The process continues till the bridges are formed in-between the particles. The powder does not get segregated since the powders are glued together at a micro-scale.

The formed granules have good solubility and are weak since no disturbance force acts on them. After the formation of granules, they are further dried using hot air. This technology used for granule formation is used for tableting & capsules due to their free flow properties, excellent solubility, dust-free, and good dispensability. The fluid bed processor is designed in such a manner that it can support different processes within a single instrument.

There are different factors which can be responsible for the choice of spray nozzle a manufacturer may include for top spraying processor like the processing option, the mode through which the instrument gets operation. It may be batch or a continuous production and many more.

3) Fluid Bed Equipment with Wurster Coater Bottom Spray for Pellet Coating or Granules Coating:

Pellet Coating is supported in the fluid bed pellet coater due to the support of fluid bed processorsystem in wurster processing to ensure smooth coating of tablets and granular particles. And the fluid bed granulation and fluid bed pellet coater machine can also handle various different processes too and is a cost-effective solution for its users.

The Fluid Bed Granulation machine is capable of handling the following mentioned processes:

  • Solvent or Aqueous based suspensions or solutions
  • Managed release coatings
  • Enteric Release coatings
  • Minute particle coatings
  • Active coatings

The Wurster process is used to apply a coating to the granules or pellets which have been passed through different process in the fluid bed pellet coater machine. The Wurster Coating process is performed in a hollow container in which the pellets enter from the bottom of the cylinder and pass through the spray guns. Here, the granules are coated and passed towards the top in a proper manner which maintains uniformity among the capsules. They are then passed to dry outside the chamber for another layer of coating in the fluid bed granulation machine. The controlled movement of all the granules assures uniformity in layering and provides quality results.

Advantages Of Fluid Bed Dryer

Firstly, our Fluid bed equipment is one of the most beneficial machines that have several advantages. One of the advantages of our fluid bed processor is that the machine has a single-unit system, which is useful in saving both labor cost and time. Another advantage is the higher rate of heat transfer option that our fluidized bed granulation machine provides. There are some other advantages like, the process is turn automated as soon as the machine starts working on adapting the system of the fluidized bed coating machine. Also, the drying system of the fluidized bed coater occurs uniformly which also helps in the process of preventing mottling.
