Dehydrator Machines (Dryer Machines)

Fruits and vegetable dehydrators are very useful and profitable machines in industrial factories and dried products in little workshops. You can have them at various costs in different kinds of dehydrator machines.

The Fruit and Vegetable Chips Production Line is one of the production lines that can be measured with low-cost equipment and machinery.

Various kinds of fruit and vegetable dehydrators

Fruit and vegetable dehydrating machines are available in different sizes and capacities industrial and semi-industrial which we will discuss in this article.

Have you ever come across dried fruits in grocery stores, nuts stores and pastry shops?

Have you used dried leafy vegetables in different foods and drinks? Have you tried using dried onions?

Have you ever thought about how and with what machines these products are manufactured? Have you ever wondered why dried fruits or vegetables are expensive?

In this article, we are going to introduce the machines and their production lines while answering the above questions about dried fruits and vegetables.

Drying and storage of fruits and vegetables and their use in different seasons has long been common and people used drying methods to increase the shelf life of these products.

Today, due to the expansion of urbanization as well as the possibility of using different types of fruits in different seasons, we reuse dried fruits and vegetables and see high sales in this segment of food. The growing domestic sales market and export sales markets around the world are market segments that can be counted on.

Types of fruit and vegetable dehydrators

The dehydrators (dryers) are classified into several types in terms of the method and technology used, each with its performance and specificity, and is well suited for the specific job.

Keep in mind that the quality and quantity of input and output products are other factors that are important in different fruit and vegetable dehydrators. Sometimes you buy a specific machine to meet specific customization requirements, and after ordering, purchasing, installing, testing and getting started, you find that this type and model of dryer makes it possible to produce a custom one. Don't be fooled, so be careful in choosing dehydrators (dryers) and avoid consulting with experienced and caring consultants.

In the following, we will briefly refer to the various types of fruit and vegetable (dehydrator) dryers and their characteristics. Stay with us.

Types of Arad Machine (dehydrator) dryer by Usage:

• Household dryer

• Semi-industrial dryer

• Industrial dryer

Freeze Fruit Dryer

Freeze dryers or sublimation dryers are high-quality end products that produce excellent dry fruits and vegetables.

The cost of designing, manufacturing, maintaining and using these machines is very high and due to the low speed of production in this way, the price of the finished products is very high. If the cost of the product is high, the selling price will also be very high, resulting in a very limited market.

In freeze dryers, water extraction from fruits is carried out using a low-pressure water sublimation process, and the fruit and vegetable tissue is less damaged and produces a better quality product.

Industrial Microwave Dryers

This type of dryer uses microwaves to heat and remove water and moisture from fruits and vegetables. In this method the working speed is high and in a short period, the machine can output high output.

Microwave dryers are powered by electricity and have relatively high power consumption. As a result, electricity costs should also be considered. The high cost of manufacturing and operating these machines also makes the finished product costly. As a result, its sales price is very high and there is less justification for the customer to buy this product.

Solar dryers for fruits and vegetables

One of the newest and most advanced types of dryers is solar dryers for fruits and vegetables which are growing and expanding day by day. These (dehydrator) dryers, which usually work in two ways, use sunlight to provide the heat needed to drain the fruit.

The direct method is that the drying products are placed in a chamber above the glass and direct sunlight shines and the chamber is heated to remove moisture from the product and the product over time to dry.

In the indirect method, the (dehydrator) dryer is designed in such a way that the absorption chamber of the sun is separate from the (dehydrator) dryer chamber and the heat absorbed by the absorber causes the chamber air to heat up and causes the hot air to move upwards. Hot air enters the drying chamber at the bottom of the sunshine compartment, passing through the fruit and vegetables upstream and drying them out, eventually leaving the top dryer.

Solar dryers are a kind of fruit and vegetable dryers that can be used in different regions to produce a variety of products and produce very good products at low cost.

Industrial Fruit Dryers by Hot Air Method

One of the most widely used and best methods for producing dried fruits and vegetables is the use of hot air machines. These machines are one of the cheapest types of (dehydrator) dryers among the aforementioned dryers used to produce all kinds of dried fruits and vegetables.

In hot air dryers, there is a heat source that generates controlled moisture output from the fruit and vegetables. The machine's circulation system is the most sophisticated part of these machines. While generating heat at one point in the machine, the heat must be transmitted in a uniform, longitudinal, transverse, and vertical manner, and then returned to the furnace again.

Sources of heat generation in industrial fruit dryers

Sources of heat generation in industrial fruit (dehydrator) dryers are energy generated by burning gas or diesel or by producing electrical resistance that is designed according to power requirements. As the body of these machines is three-chambered and there is an industrial thermal insulation layer (such as rock wool and XPS) between the layers, the heat loss is close to zero resulting in very low fuel consumption as well and the workshop hall will not warm.

The heat generating system includes a very hot furnace, an industrial burner (gas or diesel or electric elements), a burner control system, a conduit and a smoke exhaust system, and other details here.

Convection system for hot air industrial dryer

In the air circulation system of these machines, relatively complex mechanisms such as blower and suction fans, special spoilers, walls and canals and so on. All of these are designed according to fluid mechanics and heat transfer science. Maximum performance is achieved by producing a perfectly uniform product that only professional designers and genuine machine makers can do.

Consider, a hot air cabinet (dehydrator) dryer with three cabins that is about 4 meters long, the furnace is at one end of the machine, and its heat generated must be distributed by heat transfer systems such that the fruit in the first and closest row to the furnace, dry the fruit with the longest distance to dry completely. This was a small example of the sensitivity of this work, so consider that this uniformity must be observed at the top and bottom of the machine as well as the front to back of the machine.

Industrial fruit dryer control systems

Control systems in industrial fruit and vegetable dryers include systems that must control temperature, time, humidity, etc. in the drying environment of the product. These systems include sensors, wiring, indicators, actuators, and so on.

These systems should be able to monitor the environment and conditions for a moment and act on the instructions given by the professional operator. For example, when humidity reaches a certain percentage, it has to decide that smart humidity system what to do.

Therefore, it should be a very intelligent and sensitive system that can produce a very high-quality and controlled product. If you know how to use this smart, all-digital system, you can produce a high-quality product with the exact standards you want.

All markers are digital, with ease of control, command and decision-making. The quality of the sensors and other parts of the control panel of the machine must be high so that the information provided by them can be trusted. For example, when the temperature indicator shows 50 degrees, the actual temperature should be exactly 50 degrees, otherwise, the product will not be as expected and will have a different shape, color, and humidity.

Hot air industrial dryer's body

Every single detail of these machines is important and each can have significant impacts on efficiency, safety, performance, ease of use, minimum fuel and energy consumption, and so on. Among the parts and details that may seem trivial but by far the most important part of the machine is its body.

The body of the machine comprises the main body of the machine, body panels, doors and hinges and knobs, boxes and flaps connecting various parts of the machine such as switchgear and torches, wheels and pedestals, and the wall and other details.

The body is usually three-walled in most parts, with two main bodies and one wall comprising spoilers, canals, and so on. The body comprises an industrial thermal insulation layer that can prevent heat loss and reduce fuel consumption as well as warming the outside environment.

High-quality wheels that can handle up to one ton of heavy machines have a good performance. Powerful chassis that can withstand constant weight as well as move with the crane and prevent the machine from being deformed.

Doors must have all the requirements of heat and insulation while being removable and keeping these features light. Door hinges and door handles are also important in terms of performance, comfort and safety.

Moisture insulation is another important factor that should be considered in the body of industrial fruit and vegetable dryers. The exterior of the machine is most often made of galvanized steel sheets and is covered with electrostatic or automotive paint which is highly resistant to moisture and has a good beauty.

The interior body of the machine is often made of galvanized sheets, which are stainless and suitable for this area. Consider, of course, what the machine is going to do and customize the body from stainless steel and galvanized sheets, and so on.

Production capacity of industrial dryers of fruits and vegetables

(Dehydrator) dryers are designed for use in various operating levels and a variety of Household, semi-industrial and industrial capacities. In large factories usually used for multiple machines. In general, it can be noted that the capacity of tunnel dryers is greater than cabinet dryers.

Usually, cabin dryers have an inlet capacity of about 100 to 400 kg each time. Continuous dryers, or tunnels, have a capacity of about one to two tons per shift.

In the other articles, we will introduce different types of dryers and discuss their input and output capacities in more detail.
