The Principle and Application of Tray Dryer

The tray dryers are also called cabinet dryers. There are horizontally arranged trays and the material is spread out on that trays for drying. The air is heated using conduction or radiation and inserted into the trays. The heated air is useful to remove the moist vapors.

Principle:

The dryer chamber contains trays which are horizontally arranged in a column. The wet material to be placed on these trays in thin layers and with the use of circulating fan, the heated air is inserted vertically on the trays. The exhaust fan removes the wet air out of the chamber as fresh air is inserted. The air is equally distributed within the dryer with perforated plywood floor. The air does not bypass from the trays as they tightly fit into the cabinet.

Application:

The tray dryers are commonly used to dry food materials and it will dry on the food on the base of food type and the desired final moisture. Normally, it will take 10 or even 20 hours to dry the wet food products.

Sparkler Filter Press – A Standard Flow Type Filter Press Machine

The sparkler filter press is a standard filter press machine that is used to filter out solids from liquid slurry. The machine is mainly used in industries like pharmaceutical, chemical, food processing, cosmetic and beverages. This is one standard machine which is utilized in areas where the filtering process is important to complete the production process. All the solid liquid mixture which is produced by large liquid manufacturing industries are in the form of slurry or thick mud so it needs to be separated before being used.

There are so many sparkler filter press manufacturing industries available in the market. Different sizes are available as per the need of the customer and as per the nature of the liquid. The whole sparkler filter press is made out from standard quality stainless steel. The container is bolted with top cover to successfully complete the filtration process and it is sturdy enough to maintain and develop the pressure. The container has a number of horizontally placed filter plates with perforated supported screens, interlocking cups and filter media. The whole machinery stands out on a stainless steel trolley so the machine can be easily moved and can be attached to other machines.

The impure liquid centrally fed under high pressure from bottom inlet and goes to the top of each plate. It spreads equally on each filter plate. The solids remain on filter media and filtered liquid goes out the shell and then to the outlet. The sparkler filter press can provide almost 100% filtration of liquid which we cannot get from other filter press machines. With the use of air the cake can be dried at the end of the filtration process.

Fluid Bed Dryer Works on Fluidization

Introduction

Fluid bed dryer is widely used by pharmaceutical, chemical and foodstuff industries. It is used to dry materials with hot air and the process are called fluidization. The fluid bed dryer is constructed using S.S. 304 quality stainless steel material. The machine contains a horizontal bed where the fluid is lying for fluidization.

How it works?

In fluid bed dryer, the hot air inserted into the container using air blower. The air is heated using steam or gas at the bottom of the machine. As the air heated the material, it moves and expands in the container at a certain velocity and retain the turbulence in the product. The heat transfer is extremely high and uniform and the product dried fast without appreciable loss of heat.

Fluid Bed Dryer

Suitability

The fluid bed dryer requires less space compared to other dryers. It is very easy to operate and you can dried the material in a very less time. So, it gives high production rates. The fluid bed dryer is most suitable for drying granular, crystalline, coarse or similar material in pharmaceuticals, fine chemicals, dyes, food and allied products. It is not suitable for drying liquids or pasty materials.

Silent Features of Sparkler Filter Press and Zero Hold up Filter Press

Both sparkler filter and zero hold up filter presses are used to solid liquid separation. The constructions of both machines are same.  But they have different working mechanism. The sparkler filter press is also known as horizontal filter press because there are horizontally arranged plates in filter cartridge assembly. The zero hold up filter press known as reverse flow zero hold up filter press because it works in reverse manner compare to sparkler filter press. The machines have some important parts used in filtration process are as follows.

Filter Media – The area which collects the impure liquids

Liquor – The solution containing liquid and solids

Pump – Used to feed the slurry into filter press

Cake – The solids filtered out of the liquid

Sparkler Filter Press

Features of Sparkler Filter Press:

• The sparkler filter press stops water loss, corrosion, leak and waste getting out of from product.
•  The filter plates are available in two sizes: Deep and Shallow
