The history of harvesting dried fruits, berries, mushrooms and vegetables is rooted in the distant past. Lacking devices and equipment for long-term storage of food, people have learned to store food for the winter by drying it in the fresh air. This method has been preserved to the present.
Its efficiency and labor costs are fully justified by the end result:
Everyone knows firsthand about the benefits of dried foods.But still, it should be noted that daily consumption of a small amount of such vegetables, berries, mushrooms, dried fruits provides the human body with the necessary vitamins and minerals, maintains its balance. Such ingredients have a significant effect on the gastrointestinal tract, the work of the cardiovascular system, and strengthening the immune system.

Due to the fact that drying products in natural conditions (in the sun) or using ovens has a number of inconveniences and disadvantages, scientists have developed special devices designed to dry various food products in comfortable conditions and with minimal labor costs.
In today's consumer markets there are a huge number of dehydrators of various configurations, specifications and price categories. Depending on the amount of dried fruits, berries, vegetables, mushrooms, meat consumed, as well as the number of family members and the level of the budget, each consumer can choose the best version of the device for use.
The range of products for which an electric dryer can be used is very wide. In most cases, housewives do not pre-prepare them, but in order to preserve the original color, aroma and taste, some of them resort to the following manipulations:
When carrying out such procedures, the development of microorganisms that spoil products is slowed down. But at the same time, it should be remembered that an attempt to restore food with the help of water will again resume their vital activity. Therefore, the use of these pre-treatment methods is effective when fruits, berries, vegetables, meat and mushrooms are consumed in dried form.
To accurately determine whether a particular product is sufficiently dried, it is necessary to allow it to cool completely. If the slice is still soft or sticky, then the procedure should be continued until these signs are completely eliminated.
To preserve the maximum amount of useful substances after drying, experts in the field of preparations advise fruits with vitamin C to be cut into larger portions, since when divided into small pieces, a significant loss occurs.
Vegetables containing vitamin A should then be stored out of the sun.
Experts also note that an increase in the sweetness of some berries and fruits after drying is a normal phenomenon, justified by loss of moisture and an increased concentration of sugar content.
An important condition for the long-term and high-quality use of dried fruits and other dried products is the complete absence of moisture in the containers where they are stored.Therefore, all jars and containers must be pre-treated at high or low temperatures. To do this, they are either placed in the oven for 20-30 minutes. at 75°C, or sent to the freezer for 48 hours. After such a procedure, the possibility of the appearance of food moths in them will be excluded.
To avoid the formation of yeast or mold fungi on dried slices, the container should be covered with tight lids. Otherwise, when the product is in the open air, there is a high probability of moisture getting into it. As a result - the loss of quality and taste characteristics.
There are some features for storing meat preparations. They are as follows:
Manufacturers supply two types of electric dryers to consumer markets: convective and infrared. Their difference lies in the method of removing moisture from the ingredients placed in the trays. In the first devices, this is done with the help of hot air, and in the second - with infrared rays.
These devices are a budget category of dehydrators, so they are widely popular among the middle class. Their device is quite simple and consists of an engine, one or two heating elements, a fan, mechanical or electronic control, a timer and a different number of trays.
The principle of operation of convective electric dryers is to supply hot air from the bottom up through mesh or lattice trays for the required amount of time.If there are two heating elements in the device, the temperature level is regulated by heating one and cooling the other. If there is only one heating element in the device, then the distribution of hot air, as well as the cooling of the heating element, is carried out using a fan. All representatives of convective dehydrators have thermostats of a simple type, which are responsible for maintaining the temperature at a given value.
The process of drying pieces of fruit, vegetables, meat or mushrooms takes place on special trays with a fine mesh. Hot air passes through them, absorbing the moisture contained in the products. Each subsequent layer is tightly attached to the previous one, which eliminates the leakage of air flow. The advantage of such devices is the ability to install additional trays. This increases the volume of processed raw materials in one session. At the same time, convective dehydrators have the disadvantage of significant energy consumption during long-term operation.
It should be noted that when using this type of electric dryers, the safety of vitamins is from 60% to 70%.
More expensive units for turning fresh products into dried ones use infrared rays in their work. Their effect occurs on the inside of the slices, in contrast to convective ones, which act only on the outer shell. Such electric dryers are applicable in restaurants and cafes where the processing of vegetables, fruits, mushrooms or meat requires a faster process. Also, thanks to infrared dehydrators, the vitamin reserve in dried fruits, vegetables, meat and other components is maintained at the level of 80-90%.
For electric dryers of this category, the efficiency is much higher and is about 85%, while in convective devices it is at the level of 50-70%. A distinctive feature of drying units based on the use of infrared rays is the low energy consumption throughout the entire process. And their disadvantage is their large size and high cost.
The process of drying various vegetables, berries, fruits, mushrooms, meat is not difficult. It begins with the preparation of cutting a certain type of food into plates no more than 0.5 cm thick. This is necessary so that the level of residual moisture in the slices is the same, and they dry evenly. The slices are then placed on the trays in a single layer. Light contact of the pieces with each other is allowed. When all pallets are filled, the unit is connected to a power source, set the time and required temperature on the timer (if available), and start the process.
At the end of the work, the cutting is allowed to cool and try. If the readiness is at the right stage, the pieces are collected and placed in a prepared container for further storage. Otherwise, the drying process is continued until the desired result.
There are not many positions that you should pay close attention to when choosing the optimal model. Giving priority to this or that quantity and value narrows the search circle and increases the likelihood of acquiring the most convenient and profitable dryer.
So, before going shopping, it is advisable to assume how many trays are needed for a full supply of ingredients for the winter period; how much time are willing to spend on the production of dried fruits, berries, vegetables, meat and mushrooms; how much from the family budget can be allocated for the purchase of a dehydrator. Having outlined approximate criteria, you can begin to search for a profitable offer.
Choosing from all the proposed models, first of all, it is recommended to focus on:
The standard number of trays in many models is about 5, but their maximum number can be up to 15 pieces. As described above, many dryer options have the ability to add multiple layers purchased separately from the main appliance.
The performance of the device depends on this indicator. The higher it is, the greater the volume of cuts can be dried in one process by increasing the fan speed and increasing the temperature of the heating element. This indicator shows the limit of the number of pallets that can be added to the main composition. Also, power determines the cost of energy resources necessary to ensure the efficient operation of the dryer.
Depending on the design of the dehydrator, the temperature controller can either work in three fixed positions "Low", "Medium", "High", or with the possibility of more precise adjustment of the required value. The minimum level of the value in all devices is at the level of 30 ° C, but the maximum can vary from 60 ° C to 95 ° C. But the best option is the presence of 70 ° C. This is the most common temperature for cooking many foods.
This is the only insignificant selection criterion, but it should not be neglected. Indeed, in small kitchens, every centimeter counts. Although the base area of the machine is almost the same in many models and ranges in diameter from 20 to 30 cm, a slight difference in size can play a cruel joke. The height is not so significant in choosing the best option, since it is easily adjusted by removing or adding the required number of pallets.
The price of dehydrators can range from 1000 rubles. up to 15000 rub. and higher. The main factors affecting the pricing of this category of goods are:
Some of the items listed are not so significant and you can do without them, thereby spending less money on the purchase.
