INDUSTRIAL CORROSION PROTECTION

POLYPROPYLENE TRAYS FOR DRYERS

Manufactured by Plastic Fabricators

Drying trays spend a lot of time inside demanding process environments. They may be exposed to heat, chemicals and repeated handling, so the tray material matters just as much as its size.Plastic Fabricators manufactures polypropylene trays specifically for dryer applications. Such trays are produced as a single piece using polypropylene in a molding process, providing them with a robust build without any joints, which might weaken during normal usage. Such trays are capable of withstanding temperatures up to 140°C and are resistant to acids, alkalis, and corrosive substances. In addition, their smooth surface makes them easy to clean, while their non-stick properties prevent product loss during drying and crystallization processes.

The conventional tray has dimensions of 32" × 16" × 1.25", featuring 5 mm thick walls. Specialized sizes may be produced upon request. These trays are used in chemical plants, pharmaceutical manufacturing, API production and dye industries where conventional aluminium or FRP trays may not be the preferred option.

TECHNICAL DATA

WHAT ARE POLYPROPYLENE DRYING TRAYS?

Polypropylene drying trays are used to hold material during drying or crystallisation processes.

Unlike an ordinary plastic tray, a dryer tray has to deal with more than handling and storage. It may be exposed to elevated temperatures, chemical residues and repeated cycles of loading, unloading and cleaning.

These trays are moulded from polypropylene as a single piece. The construction is rigid and designed for regular factory use.

The standard size is 32 inches long, 16 inches wide and 1.25 inches high, with 5 mm thick walls.

One of the practical advantages of the PP surface is that material does not tend to stick as readily to it. That can make unloading easier and helps reduce the amount of product left behind after a drying cycle.

For plants handling corrosive materials, polypropylene also provides resistance to acids, alkalis and other corrosive chemicals.

Why Use PP Trays in Dryers?

🌡️

Handles high heat The trays are designed to work at temperatures up to 140°C. That makes them suitable for drying and crystallization processes where ordinary plastic trays would not be appropriate. Actual suitability should still be checked against the specific dryer cycle and operating conditions.

🧪

Acid and alkali resistant In chemical processing, the trays may come into contact with harsh substances. Polypropylene is acid, alkali, and chemical-resistant, which makes it a suitable material for most chemical and pharmaceutical drying processes.

🔩

Made in one piece The tray is made in one piece. There are no assembled sections or joints across the tray body, giving it a straightforward construction for repeated factory handling.

💪

Rigid and tough A dryer tray needs to hold its shape while being loaded, moved and placed inside the drying equipment. This makes the tray tough and rigid enough to withstand daily operations in an industrial environment.

🧼

Easier to clean The smooth PP surface is easily cleaned using water, making the cleaning process easier. This is more applicable when the tray is used again from one batch to another.

✨

Product doesn’t stick on the tray When products stick on the tray, it leads to more cleaning work and loss of product. The PP surface will reduce sticking, thus increasing the amount of product retrieved from the tray after the drying process.

💰

Value for money If a tray lasts through repeated handling and process exposure, there is no need for replacement often. The product is marketed as being more durable and cost-effective compared to the aluminum trays.

TEMPERATURE PERFORMANCE

DESIGNED FOR DRYING PROCESSES UP TO 140°C

Heat is one of the first things to consider when selecting a dryer tray.

The polypropylene trays supplied by Plastic Fabricators are designed to work up to 140°C.

That makes them suitable for a range of industrial drying and crystallization processes where temperature is a regular part of production.

The actual process temperature, duration of exposure and dryer cycle should be considered before finalising the tray. A tray that works for one process may not necessarily be suitable for a different temperature profile.

CHEMICAL RESISTANCE

WHEN THE TRAY COMES INTO CONTACT WITH PROCESS MATERIAL

Chemical plants and pharmaceutical manufacturers often deal with materials that can be hard on conventional tray materials.

PP provides resistance to acids, alkalis and corrosive chemicals.

This is one reason polypropylene trays can be a useful alternative to aluminium or other materials in suitable drying applications.

Chemical compatibility should still be checked against the actual substance being processed, particularly where the concentration, temperature or exposure time is high.

PP VS ALUMINIUM DRYING TRAYS

Aluminium trays have been used in industrial drying for years. But they are not necessarily the best fit for every process.

PP trays offer several practical differences:

They resist corrosion
● They handle acids and alkalis
● They are suitable for temperatures up to 140°C
● They have a smooth surface
● Product sticking is reduced
● They can be cleaned with water
● They are manufactured as one piece
● Custom sizes can be produced for bulk requirements

The right tray still depends on the dryer, material being processed and operating temperature.

Custom PP Dryer Tray Requirements

CHEMICAL INDUSTRY

A BETTER FIT FOR CORROSIVE PROCESS CONDITIONS

Chemical production often involves acids, alkalis and other corrosive substances.

A tray used in these processes needs to tolerate the material being dried as well as the heat involved in the drying cycle.

Polypropylene offers resistance to these chemical conditions, making PP trays suitable for many chemical drying applications.

The actual chemical should always be checked before selecting the tray material.

PHARMACEUTICAL & API APPLICATIONS

Drying is an important part of many pharmaceutical and API manufacturing processes.

Trays are loaded with material, placed into the dryer, removed after the cycle and then cleaned for reuse.

A nonstick surface of PP simplifies cleaning, while decreased product stickiness helps during the unloading process.

For pharmaceuticals, specific conditions of the process and material handling need to be verified prior to purchasing.
