Product Description:
The NESCO Professional Food & Jerky Dehydrator has more power than most dehydrators -- 700 watts -- which means faster drying time. You will have results in hours, not days. The top mounted fan with patented Converga-Flow action pressurizes air downward through the outer ring and horizontally across each individual tray, converging at the center, for fast, even drying. No need to rotate trays. The adjustable thermostat allows you to dry different foods at proper temperatures (95-155 F), providing the flexibility to produce the best drying results. As your needs grow, the Professional Food & Jerky Dehydrator can be expanded up to 12 trays.

Rating : - Nesco FD-75PR 700 Watt Food Dehydrator
I purchased this dryer a couple of months ago and am very pleased with the performance of this product. You may want to purchase more of the screens Nesco American Harvest Clean-A-Screen Tray as it only comes with 2 and there are 5 trays. These help prevent dried foods that have shrunken from falling through the grates of the trays. They are also needed for fruit leathers.

The book that comes with the dryer is good for a starter but not detailed enough. For instance, if you are wanting to dry fruit for storage the best pretreatment is a sulfite dip rather than ascorbic acid or honey. Sulfites are not recommended for people with asthma. Pretreating with an acidic solution or sodium metabisulfite, sodium sulfite or sodium bisulfite (USP or Reagant grade) helps keep light colored fruits from darkening during drying and storage, helps speed the drying process of certain fruits and enhances the destruction of harmful bacteria during drying.

The book does not provide very much detail on blanching vegetables, which is necessary to destroy enzymes in the tissues and also enhances the destruction of harmful bacteria. Different vegetables have different blanching times and over or under blanching may have an undesirable result as far as loss of color and flavor during drying or storage.

The book has many recipes and includes recipes for pet treats, drying crafts, dough ornaments and potpourri.
More information on drying fruits, fruit leathers, vegetables, jerkies as well as info on food storage can be found online at the National Center for Home Food Preservation.

A good dryer is a handy tool to have if you grow veggies and fuits and like to have storage of your own creations to enjoy later.
Or make healthy snacks and foods without corn syrup.

The things you will like about the dryer are the size, variable temperature settings, the dryer is on top, very easy to handle and clean and not too noisy. Like others have said, it would be nice to have an on/off switch and a timer.
