What is a dryer?

First of all, it is better to know what a dryer is and how it is used in the industry. The fruit dryer is one of the most used and profitable devices in the industry and industrial businesses, which can be purchased at a low cost.

Dryers can be used to dry all kinds of food and edible, pharmaceutical and chemical products. The price of these devices varies according to the capacity and type of device, and it does not have a fixed price, but it can be started with a small capital.

The dryer preserves and does not destroy nutrients in products and food. So you don’t need to worry about the loss of useful nutrients in dried products. These devices only dry the water and moisture inside the food and do not harm its texture.

A dehydrator is a device used to remove moisture from food such as fruits, vegetables, herbs and meat. By creating air flow or heat, this device evaporates the moisture in the food and causes them to dry.

Types of dryers:

• Home dryer: These types of dryers are designed for home use and have less capacity and power than the industrial type.

Industrial dryer: These types of dryers are used for commercial purposes and on a large scale and have high capacity and power.

Advantages of using a dryer:

• Increased shelf life: Drying food increases its shelf life and can be stored for a longer period of time without spoiling.
• Preservation of nutrients: In the drying process, many nutrients in food are preserved.
• Variety in diet: By using a dryer, you can use a variety of dried fruits and vegetables in your diet.
• Making healthy snacks: Dried fruits and vegetables can be a healthy alternative to unhealthy snacks.

How the dryer works:

Dryers work in different ways, but generally include the following steps:

1. Placing food in the trays of the machine
2. Temperature and time setting
3. Creating air flow or heat
4. Evaporation of moisture
5. Food drying

 

What are the advantages of using a dryer?

Today, dried fruit has become one of the delicious snacks, which is very popular among people due to its high nutritional value and has a special place in people’s diet. These fruits are usually dried in private machines that have their own advantages and disadvantages.

The important point in choosing these devices depends on its technical specifications, in fact, the more features built into the device, the higher its efficiency. Therefore, in buying a dryer, it is very important to pay attention to the performance of the device. Next, we want to examine the advantages of using a dryer.

• One of the most important advantages of using dryers is to prevent food waste and rotting .
• The second thing is related to the easy use of the device and you don’t need to take a special course to learn and set it up, just put the products on the tray and set the appropriate temperature and press the power button.
• The third advantage of using these devices is drying food in a large volume in a short period of time . Fruit drying devices can accommodate many fruits due to the trays used in several rows.
• If you want to preserve the nutritional value of the products you dry, we suggest you to use drying machines, because  the enzymes and nutritious vitamins of the products are not wasted and remain .

 

Disadvantages of using a dryer

In addition to its advantages, every device has its own disadvantages. One of the main disadvantages of using dryers is their high electricity consumption, and the production of abnormal sounds is another disadvantage of using these devices, which for some People are very annoying.

The color change of the fruits is one of the other defects of these devices, which is completely natural due to the application of high temperature to dry the fruits and preserves the nutritional value of the product.

It is important to note that in some factories, to prevent the color of the products from changing, sulfur compounds are added to them, which are very harmful and carcinogenic. Pay attention to these things when buying dried products so that you don’t get complications.

What products can be dried with a dryer?

From the past until now, drying and preserving fruits and vegetables has been common among people. To increase the shelf life of these foods and products, people dried them with traditional methods. But today, due to the development and progress of the industry and also the possibility of using all kinds of fruits in different seasons of the year, the sale of dried fruits and vegetables has become very prosperous.

Not only the domestic sales market of these products is growing, but the export market is also hot and profitable. In the continuation of the discussion, which products can be dried with a dryer, we can point to products such as all kinds of vegetables and fruits such as apples, peaches, apricots, etc., which are among the most popular dried fruits.

Checking all types of dryers

The drying machine is divided into several categories in terms of manufacturing technology and technique, and each one has its own performance and characteristics. Keep in mind that the quality of the input and output product is an important factor in fruit and vegetable dryers.

 

Freeze dryer

Freeze dryers are among the devices that improve the quality of final products and produce unique dried fruits and vegetables.

The cost of using and maintaining this device is very high, and this increases the price of the final product. If the cost of the product is high, its selling price is higher and as a result, it will have a very limited market.

In freeze dryers, fruit juice is drained using the sublimation process at low pressure, and the texture of the product is less damaged, and in the end, a higher quality product is produced.

 

A freeze dryer is a device used to dry food by freezing it. In this method, food is placed inside the device and a very low temperature is produced, usually around -40 degrees Celsius or lower.   The method of operation of the drying machine is by the freezing method in such a way that cold and dry air is produced inside the machine and transferred to the food. This cold air freezes the moisture in the food and the water in them turns into ice crystals. In the next step, the device evaporates the ice crystals by gradually increasing the temperature and it is removed from the food in the form of steam. This process is known as sub-steaming.

Freeze dryer is a device that is used to dry food by sublimation (direct conversion of solid to vapor without passing through the liquid state). This method is ideal for drying heat-sensitive materials such as fruits, vegetables, medicinal plants and some medicinal materials.

How the freeze dryer works:

1. Freezing: Foods are first completely frozen.
2. Pressure reduction: The pressure inside the device chamber is greatly reduced.
3. Sublimation: As a result of the pressure reduction, the ice in the food is directly converted into steam.
4. Drying: Water vapor is absorbed by a cooling system and directed out of the chamber, and as a result, the food is dried.

Advantages of using a freeze dryer:

• Preservation of quality: This drying method preserves the taste, color, smell and nutritional value of food.
• Retention of shape: Foods retain their shape and appearance after drying.
• Increased shelf life: Freeze drying increases the shelf life of foods and they can be stored for a longer period of time without spoilage.
• Reduction in volume: Foods lose their volume significantly after drying and their transportation becomes easier.

        Using a freeze drying machine has some advantages, including preserving the taste and nutrients of food, preserving the color and texture of food, and prolonging their shelf life . In this method, there is no need to use additives or sweeteners, and the food has a significantly smaller volume than in the raw state.   However, for optimal use of the freeze dryer, pay attention to the manufacturer’s instructions and appropriate safety and health tips. Also, observe the proper time and temperature for drying each type of food to get the best results.    

Microwave dryer

In this type of dryer, microwaves are used to heat and drain fruit and vegetable juice. This device has a very high working speed and can have a high output value in a short period of time. Because the microwave dryer is electric, it consumes a lot of electricity.

As a result, we must also consider electricity costs. The micro device has a high manufacturing and maintenance cost and ultimately increases the price of the product and has less economic justification for domestic customers.

A microwave dryer is a type of fruit and vegetable dryer that uses microwave technology to dry food. Using microwaves, this device evaporates the moisture of food and turns it into a dry and lasting one.   The working method of the microwave dryer is based on the principle of producing cylindrical microwaves. Food items are placed on a plate inside the device and microwave waves are applied to them. These waves cause vibrations in the water molecules in the food and evaporate the moisture. This moisture leaves the device in the form of steam, and the food remains dry and long-lasting.    

Solar dryer

One of the most up-to-date and newest product drying devices is the solar dryer for fruits and vegetables. In these dryers, sunlight is used to provide the required heat of the device. This device works in two direct and indirect ways.

The performance of the direct method is that all products that can be dried are placed in a container whose upper part is glass; with direct sunlight entering it, the container is heated and the water in it is removed and over time The fruit dries up.

But in the indirect method, the device is designed so that the heat absorption chamber is separate from the dryer chamber. In this method, the heat is absorbed by the absorbing part of the device and causes the air inside the chamber to heat up and the hot air moves upwards.

Finally, the hot air enters the product compartment and passes through them, causing them to dry. The solar dryer is a very good and popular type of fruit and vegetable dryer that can be used in different areas to produce high-quality products.

Hot air dryer

One of the most economical and widely used devices in this field are devices that work with the hot air method. These devices are the best option for drying fruits and vegetables at a very reasonable price. In this fruit drying machine, hot air causes moisture and water in fruits and vegetables to escape.

The motion circulation and air circulation system inside this device is the most complex part of it, which transfers the heat uniformly longitudinally and transversely and then returns it to the main furnace.

A hot air dryer is a device used to dry food such as fruits, vegetables and meat. Using hot and dry air, this device evaporates the moisture of the food and turns it into a dry and lasting one.   The working method of hot air dryers is that hot and dry air is produced by a fan inside the device and directed into the dryer. There are baskets or plates on which food is placed. Hot and dry air passes around the food and evaporates their moisture. Then the moisture is removed from the device in the form of steam.   Hot air dryers have different settings for temperature and drying time. By setting the right temperature and time, you can properly dry food to preserve its flavor, texture, and nutrients.   Using a hot air dryer has advantages such as ease and speed of drying, preservation of nutrients, long shelf life and versatility in drying all kinds of food. Also, by using a hot air dehydrator, you can dry and have seasonal fruits and vegetables available at times when access to them is limited.   must read … !   The properties of dried fruit and its 7 miracles for the human body
