– Case Study – Storage and haulage of powder products

SMAC distributer for Munters in Africa

The humidity in bulk silos, often causes problems.

The storage of dry bulk products can create problems such as reduced quality of the product, loss of production, blocked ducts, plant damage and need more regular maintenance. The result is lower production and higher costs of production.

Operators of silos or pneumatic conveying systems are aware of the negative effects of excessive humidity. These are difficult to combat as humidity levels change throughout the day and during different seasons.

To minimize the effects of this plugging, are added to the equipment devices such as vibrators, hammers, etc.

However, this does not solve the problem: the product is still sticking and transmission lines blocked.

Protection all year round

Munters offers a proactive solution to control the relative humidity and the dew point of the air. (The dew point is that temperature at which the humidity begins to condense on the walls or products.)

Munters desiccant dehumidifiers control humidity in both double-walled silos in single wall, effectively. Our equipment is used to prevent condensation and other moisture related problems.



Storage silos

Hygroscopic materials such as sugar, cocoa, starch, salt, chemicals, odors, etc. are stored in silos. A high content of moisture or condensation on the walls of the silo due to fluctuations in the outside temperature, causes the growth of bacteria and the product sticks on the walls of the silo. The humidity inside the silo is absorbed by the product, causing clumping and thereby causing problems in handling. These problems cause costly production downtime.

RH 65% or higher will support the growth of bacteria. Dehumidifiers keep the air inside the silo to a safe HR, preventing the appearance of health problems and handling during storage.

Dry bulk handling dehumidification


Many small manufacturers and final customers use Munters dehumidification systems to ensure the right conditions of moisture in the transport and storage of bulk products.

Munters Global client references are: Nestle, Taradellas House, Kraft Foods, Danone, Panrico, Gallina Blanca, Chocolates Valor, Radar Process, Solid System Technik and Buhler.

When hygroscopic ingredients and powders absorb moisture they become sticky and build up inside the conveying lines. The resulting flow problems slow the process, create sanitation concerns and eventually cause costly downtime.

Pre-drying the air using a Munters desiccant dehumidification system ensures that the products are transported in a dry environment. The result is quick and continuous problem-free conveying with no unscheduled production stops.

Many high volume manufacturing companies receive their ingredients by truck or by rail. Pre-drying the air used in their pneumatic conveying ensures that products are transported dry into the silos. Furthermore, the same dehumidified air used for conveying can be delivered into the silo or hopper, and will not cause the ingredients inside to solidify.

The Munters dry air system is the simplest, most precise way of achieving and controlling the accurate humidity conditions required.
