Since 1984, Midwest Freeze-Dry, Ltd. has been the industry leader using vacuum freeze-drying, freeze drying, vacuum thermal drying and other highly specialized methods of treatment for restoration and conservation of books, documents, files and other types of damaged materials. Our vacuum chamber can perform specialized drying including, vacuum freeze drying, freeze-drying, thermal drying, cryogenic drying and plasma fumigation solutions. We focus on both non-chemical methods of the vacuum freeze-drying process and our proprietary low cost, yet effective plasma vacuum chamber technology for drying wet materials, mold remediation, pest infestations, and odor removal.  Our vacuum freeze drying experience has enabled us to develop advanced cost-effective concepts which can be applied to your conservation and restoration needs. From schools to commercial buildings, our vacuum freeze drying and freeze drying services can handle your: water, fire, mold, or smoke damaged books, vellum books, textiles, wooden objects, documents, vellum documents, paper documents, artwork, memorabilia, photographs, comic books, CDs, DVDs, drugs and food to name a few.

We are a specialized and dedicated firm that uses the most up to date scientific methods to treat water damage without damaging ozone. We spend a large proportion of our time in the research and development of new non-chemical technologies to be applied to the restoration and conservation of water damaged books and documents and are consulted by other conservation professionals daily.

At Midwest Freeze Dry no ozone bleaching or environmentally dangerous chemicals are used in the vacuum freeze dry process to treat mold on leather books, vellum books, paper books, documents, artworks and textiles after water damage and there are no harmful gasses or waste to dispose. We have adapted a cost-effective, scientific, vacuum freeze drying method which is normally used in decaffeinating coffee to kill molds. Independent clinical tests prove that our vacuum freeze drying is capable of reducing molds by 95%. Our vacuum chamber is a cost-effective treatment that uses near and supercritical carbon dioxide which effectively destroys molds and bacteria after water damage. The vacuum freeze drying process is suitable for books, documents, archival records, art works and textiles. Our vacuum freeze drying method has taken us several years to develop. The vacuum freeze drying process is non-destructive and environmentally safe unlike other methods.

Freeze-drying is a technique by which material is frozen, then dehydrated by sublimation, with complete retention of form. In the first step before vacuum freeze drying, the water damaged documents and water damaged books are quickly frozen. This minimizes large ice blocks which can damage the paper in water damaged leather or vellum books, paper books, or documents. Sublimation is the process by which the contained water passes from a frozen to a gaseous state.

Frozen material is placed into a vacuum chamber where the freeze-drying process takes place. The time needed to completely dry materials varies according to the thickness of a volume, type of paper and the degree of saturation. Vacuum freeze drying is noninvasive and produces no chemical damage.

Normal freeze drying is a good second step if the water damaged textiles, water damaged books or water damaged documents being treated contain water but is not without its drawbacks. Freeze drying removes the water, but on its own, freeze drying is an unacceptable form of treatment for mold on books, papers, and documents after water damage. This is because mold has a protective mechanism within its life cycle which can help it to survive against such extremes as freezing and desiccation. When this occurs mold forms rough, thick walled protective coatings called zygosporangia which allow it to become metabolically inactive until such time that conditions improve (conditions where the temperature is warmer and there is more water). Many laboratory suppliers make use of this mechanism and commercially freeze dry mold samples to sell to researchers. So, normal freeze drying is not enough, further treatment is required.

Midwest Freeze Dry, Ltd.'s  innovation involves the process of decontamination which is continued using a series of other techniques. After vacuum freeze drying the material is treated with plasma. The plasma is generated using a dielectric field and a special mix of gases which are all contained in a customized vacuum chamber. 

Plasma is considered by physicists to be a fourth state of matter. It is a highly ionized neutral gas in which the number of free electrons is approximately equal to the number of positive ions. Particles present in the plasma such as ions and free radicals have a high activity and do the work on the moldy books, documents, papers, photographs, manuscripts, maps, slides, microfilm, microfiche, x-rays and books. Their high activity is related to the process pressure.

After plasma treatment the leather books, vellum books, paper books or documents are treated with carbonic acid. Carbonic acid (H2CO3) is a dibasic acid which is formed when carbon dioxide is dissolved in water. It is a chemical reaction which occurs in nature when rain water is formed.

Midwest Freeze Dry acknowledges that freeze drying alone does not kill mold. We believe that further treatment with supercritical and near supercritical CO2 is a satisfactory and environmentally safe mold treatment for materials such as water damaged documents and water damaged books. No ozone is used in any of our processes because our research has shown that paper is degraded by bleaching causing accelerated aging and subsequent fading and loss of tensile strength. It also reduces the life expectancy of vellum books, paper books, documents, paper, archival records, flight logbooks, art works and textiles.

Our new non-ozone process has been used to treat numerous libraries, collections, legal documents and as an alternative to replacement in insurance claims.

In addition to our unique non-ozone mold treatment, we provide a number of supporting restoration services.

Our team can ascertain the level of damage caused by fire, soot, smoke, water and mold to water damaged  leather books, water damaged  vellum books, water damaged paper books and water damaged documents, including on site assessment and can co-ordinate with your staff to ensure that your disaster response is timely, efficient and does not cause the situation to worsen, saving you time and money.   

We can co-ordinate with your staff to catalogue and to pack and safely ship all your books and documents.

At your request your books and documents can be clipped, cleaned and re-filed.

Take some time to explore our site and learn about the benefits of vacuum freeze drying as well as freeze drying, plasma fumigation and our other conservation/restoration methods. These useful and cost-effective tips will help you develop a disaster plan, as well as mitigate and manage your plan should an event occur.  You will also gain valuable insight into how our vacuum chamber is used to restore and/or conserve your valued items.
