Thermal Solids Processing

Thermal solids processing technology innovations

In many dry material processing systems, thermal treatment of the bulk product is required. It is often necessary to heat the product during a production process, for example for crystallization, degassing, prevention of condensation, drying of internal or external moisture, or preparation for downstream thermal processing sections (such as extrusion). Bulk solids cooling is a common step in many industrial processes.

Whether it is volatiles removal, calcination, controlled atmospheres treatment, or something else, thermal processing technologies are bringing a lot of opportunities to add value to the common and specialized materials.

Thermal processing refers to changing the temperature of a material resulting in changing its state in some way. The thermal processing technology is used in heavy manufacturing industries for processing metals and materials, as well as for industries such as food and beverage, pharmaceuticals, chemicals, and many other applications.

Plate heating transfer technology has transitioned to the forefront of bulk-solids heating, cooling, and drying. It has found use in unlikely places such as polymers, chemicals, and even olive pits.

Plate heat exchangers offer indirect heat transfer because the two streams are separated. This means contamination between the stream being heated, cooled, or dried, and the effect of the heat transfer does not occur. Using bulk heat exchangers for heating or cooling material indirectly results in removing the risk of contamination and reducing the need for ventilation or dust collectors.

Heat exchanger industries

Bulk solids heat exchangers can be used in different multiple industrial sectors, such as the chemical industry for cooling fertilizers, the food industry for cooling sugar, coffee, and more. They can also be used in the metallurgical industry for cooling foundry sand, but also in the energy industry for heating vegetable seeds.

 

Bulk solid coolers are engineered to efficiently cool a variety of free-flowing bulk solids such as fertilizer, chemicals, plastics, dried biosolids, minerals, and many other types of granular, crystals and powders.

The basis of the bulk solids cooler technology is the gravity flow of product moving through a bank of heat exchanger plates cooled with water.

Bulk solids cooling generally occurs near the end of the processing sequence when powders or bulk solids must be cooled before storage or packaging to allow for safe handling and storage. Bulk solids cooling can be necessary if the production temperature is high, but the solids are processed downstream at a lower temperature.

The cooling process

The heart of the bulk solids cooler is the bank of exchanger plates. The product to be cooled moves slowly between the plates. Cooling water flows through the plates in counter flow and the product is cooled by conduction. Mass flow of the product is achieved using a discharge feeder mounted as an essential part of the exchanger below the plate bank.

Drying solid materials is one of the most common and important in the chemical process industries since it is used in essentially every plant and facility that manufactures solid materials, in the form of powders and granules.

Drying is defined as the removal of water or other liquids from a solution, suspension by vaporizing it. It is a complicated process that involves both heat and mass transfer simultaneously, together with physicochemical transformations. Drying occurs as a result of the vaporization of liquid by supplying heat to wet granules, feedstock, filter cakes. and so on. Based on the mechanism of heat transfer that is employed, drying is categorized into direct, indirect, radiant, and dielectric or microwave drying.

Solid Drying Methods

Where fluid bed dryers are the most popular choice, they mainly handle solid feeds composed of discrete particles. There are other popular methods for drying solids materials, such as flash, tray, rotary tray, and then the fluid bed dryers.

Experts for Thermal Solids Processing

Arie Srugo was born in 1960 to the late Yaakov Srugo, who established his first factory for the production of industrial machinery in 1954 in Argentina.Ltd. “. In the mid-1970s, the factory was moved to the southern town of Netivot. Arie Srugo was employed in the factory as a salesman from the age of 16 and “pumped” into it the knowledge regarding machines for industry from an early age. In 1981, after his release from regular service in the army, Arie Srugo joined the company and was appointed its VP of Marketing. As part of his role as VP of Marketing and as CEO of the company, Arie Srugo has accumulated vast knowledge regarding industrial equipment in general and mixing equipment in particular. The company under his management began to export its machines all over the world and gained a great reputation among the companies in Israel. As part of his extensive activity in the field, Arie Srugo engaged in consulting, characterization, process planning, and adaptation of various industrial equipment to the company’s many customers. In addition, the company engaged in the planning and management of entire projects that the PerMix company undertook. Here in fact began to accumulate vast knowledge and experience in the field of planning and management of projects in the field of process for industry. PerMix, headed by Arie Srugo, has also managed projects abroad in various and varied fields. Throughout PerMix’s years of operation, the company has grown from primarily manufacturing under OEM contracts, building some of the largest brands in the industry, to complete, turn-key processing lines under the PerMix name.
