How to make a food dehydrator (food dryer machine) in this article, for those who want to start manufacturing these kinds of machines or get more information will be taught.

As you know, dried products such as fruits and vegetables, meat, herbs, etc. are gaining more and more fans and have high sales in the market. Therefore, the production of dried fruit is expanding as a professional business with industrial drying machines (dehydrating machines). For this reason, more manufacturers are trying to provide the best dryer available to producers of dried products.

In the continuation of this text, we will introduce the types and methods of manufacturing industrial dryers (dehydration machines).

Types of industrial food dryers

• Solar dryer
• Freezer dryer
• Micro dryer
• Hot air dryer

industrial food air dryer machine 

Industrial food air dryer machines are one of the most widely used and common dryers. The cost of manufacturing this machine is much lower than other dryers. Therefore the most number of food dryers that are manufactured are of this type.

Any type of food including fruits and vegetables, meat and seafood, chemicals and medicines, etc. can be dried by air food dehydrator machines.

In addition, the cost of producing dried products using air dryers is way lower than applying other types of dryers. so the application of these dehydrator machines is also cost-effective for producers.

How does an air food dryer work?

In the following, we will explain how does an air food dryer works?

This type of fruit dryer, as its name suggests, works by releasing hot air. In this method, a heat generation source is installed in this machine, which reduces the moisture of the product inside the machine by releasing heat. the air circulation system is one of the essential pieces of equipment for this type of dehydrator machine. this system, by making the hot air being circulated, makes the output product uniform and dehydrated to the desired amount.

Sources of energy in a hot air food dehydrator

Sources of energy production in a hot air food dehydrator (dryer) are gas, diesel, or electricity (which are designed according to the required power of the machine).

Dryers made by different manufacturers vary in terms of quality and efficiency, but it should be noted that the body of Arad machinery industrial food dryers is three-walled and has a layer of industrial thermal insulation (such as rock wool and sandwich panel) between Walls to reduce heat loss to almost zero. Therefore, the fuel consumption of Arad machinery dryers is very low and the surrounded environment will not get warm.

The heat generation system in these dehydrator machines includes very hot furnaces, industrial gas or diesel burners or electrical elements, burner control systems, ducts and exhaust systems produced by burning gas or diesel, and other details.

air fruit dryer convection system

In an industrial air fruit dryer, a convection system uses relatively complex mechanisms such as blower and suction fans, special spoilers, and walls, which are designed according to the sciences of Fluid mechanics and heat transfer, etc. More accurate and professional design of industrial drying machine systems maximizes the efficiency of the machine and minimizes energy loss and cost, as well as provides a uniform product.

For example, consider a 3-cabin dryer that is 4 meters long. The furnace is located at the bottom end of the machine and all the products placed on the trays, from the closest slice to the furnace to the farthest, should be dried evenly and to the desired extent. For this purpose, it is necessary to even out the heat inside the machine as much as possible so that all the slices inside it reach the same amount of heat.

control panel system of dryer machine

The control panel system of an industrial food dryer machine is intended to adjust the time, temperature inside of the machine, humidity level, and so on. This system includes sensors, wiring, indicators, actuators, and so on.

The control panel system of a dryer machine can have intelligent control and monitoring of the environment and conditions at the moment and make decisions according to the instructions given in advance by a professional operator.

For example, when the humidity of the machine reaches a certain percentage, it is decided what is the best way to dehumidify.

Therefore, the control panel system of industrial dryers must be very accurate, sensitive, and intelligent to provide higher quality products.

All Arad Machinery industrial dryers, equipped with digital control panels that control and apply for the program, are easily done in them.

The quality of the sensors and other parts of the panel should be high enough so that the information provided by them can be trusted. For example, when the temperature on the board shows 70 degrees, the actual temperature should be the same, otherwise, the final product will not be as we expected.

Body of Industrial food air dryer 

The body of an industrial air food and fruit dryer, like all other components of this machine, plays a very important role in its efficiency of that, which includes consuming as little energy as possible, providing high-quality products, ease of application, safety, etc.

As mentioned, the body of Arad Machinery dryers is three-walled, with two walls being the main body and one being spoilers, and so on.

The body of the Arad Machinery food dryer includes a layer of industrial thermal insulation that reduces fuel consumption and prevents heat loss and heating of the surrounded environment.

Arad machinery fruit dryers also include high-quality wheels that can withstand the weight of about one ton of the machine and have high efficiency and performance.

The chassis of Arad machinery food dehydrators are so powerful that they can withstand the high weight and are not damaged or deformed even when moving and transported by cranes.

The doors of industrial dryers must have all the conditions of heat preservation and insulation while they are movable. The lightness of the door is also very important.

Body material and paint quality used for the body of the machine plays an essential role in protecting against moisture.

The outer body of the Arad machinery food dryer is made of steel and the paint used is so resistant to moisture.

Material of the inner side of Arad machinery fruit dryers is made of galvanized or steel sheet, which is durable and stainless.

Production capacity of industrial food dryers

The production capacity of industrial food dryers is very different and varies depending on the size of the machine and the type of input product. Industrial machines manufactured by Arad Machinery, from the smallest models, ie minor, mini, and single-cabin cabinet dryers, to the largest model, ie industrial tunnel dryers, can dry the product from 10 kg to several tons per shift.

The capacity of food dryer machines and the amount of dry products depends on the size of the business. Small and Home Businesses require small cabinet dryers while large businesses may apply multiple three-cabin or six-cabin or tunnel dryers.

How to make a home food dehydrator

You may be wondering how to make a home food dehydrator. home food dryers are just as commonly used as industrial dryer machines and also are very efficient for low volume production.

Arad Machinery home food dehydrators are structurally very similar to industrial models and the same parts with the same features are used only in a smaller size.

Other types of food dehydrators:

Industrial solar food dryer

An industrial solar food dryer works in such a way that sunlight plays the main source to supply the energy needed to dehumidify and dry the product.

Drying food (dehydrating food) using solar dryers is done in two ways.

The first method, which is called the direct way, is that the product is placed in a container with a glass roof for drying, and with the sunlight, the container is heated. As it heats up, the water inside the product is drawn over time and dry.

The second method of drying products with solar dryers, which is also called the indirect way, is such that the container that absorbs the sun's heat is separated from the drying one. In this method, heat is absorbed by the absorber part of the container and causes the hot air to move upwards. Hot air enters the dryer part at the end of the sunshade and passes through the product on the way upwards and dries it, and finally leaves the highest part of the dryer.

The advantage of an industrial solar dryer is the low cost of drying the product.

industrial Freezing dryer machine

industrial freezing dryer machines which work in the freezing method are also called sublimation dryers that produce high-quality products.

In freeze dryers (freeze dehydrating machines) dehumidification of the product is done by sublimation of water at low pressure, the texture of fruits and vegetables is less damaged, and finally, a better quality product is produced.

One of the disadvantages of manufacturing and applying industrial dryers in the freezing method is the very high cost of designing, manufacturing, and maintaining the machine. Also considering that the freeze dryer machine dries the product at a low speed, it is not economical and causes an increase in the final price of the product.

Industrial microwave food dryer

waves in industrial microwave food dryer heat and remove moisture from fruits and vegetables and any other kind of products.

The speed of food drying in microwave dryers is very high and a large volume of the product can be dried in a short time.

One of the disadvantages of using a microwave dryer (microwave dehydrator) is that it is an electrical machine and consumes a considerable amount of electricity, which in turn increases the cost of final production. Of course, the cost of manufacturing these food dehydrator machines is very high, so we can say that these machines are not very economical.
