Industrial Food Dryer: The Ultimate Guide Humans have been preserving food for ages. The process enhances the food's shelf life and prevents spoilage.In ancient times, open drying and salting were standard food preservation methods. However, food preservation techniques have evolved a lot over time.Today, advanced machines are utilized to minimize the growth of microorganisms in food. One such machine is – an industrial food dryer.Also known as a commercial food dryer, this food drying machine eliminates moisture from food. It can dry various types of foods on a large scale.If you want to buy a commercial dehydrator, this blog post is for you. It discusses the benefits, and applications of an industrial food dryer.Before we jump on these sections, let us learn why food preservation is crucial.Importance of Food Preservation and ProcessingProviding safe and wholesome food to nationals is a crucial yet challenging task for every country. It is not possible without a proper food processing and preservation system.Food preservation guarantees the availability of safe and quality food. It improves the shelf life of food and retains its nutrients for a long time. It naturally minimizes food wastage.Food preservation also has a significant role in making diverse foods available throughout the year.How Does an Industrial Food Dryer Work?The working of an industrial dryer machine may vary based on its model, design, and heat source. Nevertheless, the basic principle is the same in every food drying machine.Generally, an industrial dryer machine features a drying compartment. It is where food is put for drying. This compartment is a walled space that lets heat air come inside and dry food.The heat source for the machine can be natural gas, electricity, biofuel, steam, etc. The commercial dryer releases hot air into its chamber to dry the object inside. The air heat circulates throughout the chamber with the help of a blower or fan.Let us learn what makes an industrial dryer machine different from conventional preservation methods.What Makes Industrial Food Dryer Different from Other Preservation Methods?The demand for industrial food dryers is continuously growing. A report reveals that the global food dehydrators market may reach USD 3.51 billion by 2030. This estimated growth would happen with a CAGR of 6.12%Industrial Food Dryer vs. CanningCanning is one of the famous traditional food storage solutions. It involves sealing food in an airtight vessel.Canning can extend the shelf life of food up to 5 years under ideal circumstances. Unfortunately, the canning process is a time-taking process.Commercial food dryers remove moisture from food and stop the growth of bacteria. Furthermore, it is a quick process.Industrial Food Dryer vs. FreezingFreezing is another conventional method for food preservation. As the name indicates, the process involves preserving the food at freezing temperatures.It stops the growth of bacteria and enzymes. Furthermore, it also preserves the nutritional value of food.On the other hand, an industry food dryer preserves food by removing its moisture content. It is better in terms of drying efficiency and versatility.Industrial Dryer vs. RefrigerationThe refrigeration process works similarly to freezing. Food is not frozen entirely but rather refrigerated.Refrigeration maintains the quality of the food. However, it can’t preserve crops and grains. Moreover, refrigeration can’t preserve your food for a long time.An industrial food dryer can preserve fruits, vegetables, nuts, etc.Each food-preserving technology has different applications. They cannot take each other's place. Even industrial food dryers have various types and models. Let’s learn more about them.Types of Industrial Food DryersYou can find various types of industrial food dryers in the market. Each meets distinct food production needs.
