Drying vegetables and fruits- an inexpensive and not very complicated way to preserve them. Such canned dried fruits are perfectly stored, do not require cool rooms and do not take up much space.

Plan. Dried fruits and vegetables are always in great demand among the population. Dried fruits are usually purchased in large quantities by food industry enterprises, schools, kindergartens, canteens, cafes and other catering establishments.

For the production of dried vegetables and fruits, it is advisable to purchase appropriate equipment. Fruit and vegetable dryers that ensure excellent quality of dried products are produced by some companies. One of them is “Feruza.” Manufacturers offer household drying cabinets “Vostok” and “Pichuga”, which use infrared rays that are completely harmless to humans and the environment. Such rays are well absorbed by the liquid contained in vegetables and fruits, but are not absorbed by the tissue of these products, and due to this, moisture is removed at a low temperature (40-60°C). With this processing, all useful substances, vitamins, aroma and even color are almost completely preserved. Drying time depends on the product itself, taking into account humidity and ambient temperature.

The fruit and vegetable dryer “SUKHOVEY” is used mainly for drying medicinal herbs, root crops, fruits, berries, mushrooms, which are blown with warm air during processing, and by quickly removing it from the working container with a fan, higher quality is ensured.

The Feruza company produces the industrial drying unit "Nadezhda" with a product load of up to 30 kg, semi-industrial drying cabinets "Universal" with a load of up to 70 kg, "Univesal-2", "Univesal-3" and a mini-complex for processing agricultural products using infrared drying (performs blanching, cleaning, washing, cutting, drying, grinding, packaging, as well as weighing; the price of this mini-complex depends on certain components).

For a full production cycle of dried products, you can purchase a set of equipment from the Elf-4M company (Ryazan). The characteristics of the following two models can be seen in the table:

You can purchase only the IPKS-064 drying module or the Universal drying cabinet from the Elf-4M company.

Drying cabinet ShS-1 can be purchased from Penzmash OJSC.
Before you start drying, the raw materials must be prepared: sorted, sorted, removed spoiled, unripe and over-ripe.

Fruits and vegetables are thoroughly washed in running water, inedible parts are removed (stems, skins of root vegetables, etc.), cut into circles, strips, strips, slices. To prevent the raw material from darkening during drying, keep it in a solution of salt or citric acid (5-10 g per 1 liter of water). Sliced ​​vegetables and fruits are blanched, laid out in a thin layer and dried in special cabinets.

When drying, a natural reduction in the weight of products occurs. The yield of dried products from 1 kg of raw materials is presented below:

Each type of fruit and vegetable has its own drying technology. For example, before drying, ripe beets and carrots are boiled for 20 minutes after the water boils, and then cut and dried. There are several drying methods for apples (depending on the varieties). Small pears can be dried whole, after boiling them in sugar syrup (100-150 g of sugar per 1 liter of water), and large ones can be dried cut into several parts. It is better to dry Hungarian plums (any kind can be used) in several stages with breaks. To prevent dried apricots from darkening during drying, they are fumigated with sulfur for 2-6 hours (2 g of sulfur per 1 kg of apricots), and then dried at temperatures up to 70 ° C. Some fruits and vegetables are dried immediately in cabinets at a certain temperature, others are first dried in the sun and then dried, others are first dried in cabinets for some time, then in the sun, then dried at a lower temperature again in cabinets.

You can purchase vegetables and fruits (in addition to your own) from summer residents, in villages, villages. In good years, apples, plums, carrots, chokeberries, as a rule, are sold very cheaply. If possible, buy fruits in the southern regions of the country. It is advisable to grow greens (dill, parsley, celery, etc.) on your own farm.

Dried fruits are not only a good remedy for vitamin deficiency in the cold season, but also a tasty ingredient that is added to baked goods, meat dishes, etc. The cost of dried fruits has always been high, which is why they are produced in many professional kitchens of restaurants, canteens, cafes, etc. yourself, using a fruit drying machine, which you can buy with delivery in the VitrinaStore online store.

Dryers are available in two types.

Convection drying for food

This is budget equipment intended for small catering establishments. The principle of operation of the device is to lay out pre-washed fruits, vegetables and berries on the trays of the device, then connect it to the power supply. To dry food evenly, it is necessary to change trays from time to time.

The working process in the device occurs when hot air is activated, evenly distributed throughout the internal space. At the same time, the products lose some of their vitamins, and their color and taste also change slightly.

Infrared dryers

When processing products, infrared rays are used here, having different lengths and penetrating into the thickness of the fruit, etc., up to 10 mm, being absorbed by the liquid contained in the pulp.

Vegetables and fruits can be eaten not only fresh - this is why special food is needed. There are several drying methods, and each method can be associated with its own group of special equipment.

Methods for drying vegetables and fruits

One of the first methods used in production was the conductive method. To bring the technology to life, a heated surface was needed, and nothing more - products that needed to be dried were placed on it and waited until enough moisture had left them. Today this method is practically not used, because it is extremely ineffective.

The product is heated unevenly, many nutrients are simply lost due to severe overheating of vegetables and fruits, so if you want to produce a high-quality product, you will have to abandon equipment that works according to this scheme.

The advantages of such an installation include the extreme simplicity of the device and low price (the latter is very important for beginning entrepreneurs with a small budget). But you shouldn’t focus on price alone, even if you have problems with money - a product of such low quality will take a very long time to pay for itself.

The thermoradial method of drying products is one of the most used in this area. Drying equipment for vegetables and fruits using this technology allows you to preserve maximum nutrients in the product. This is achieved due to the relatively low temperature at which drying is carried out.

In addition, with such drying, the product does not lose its attractive appearance and retains its natural, pleasant color - buyers will be much more willing to buy it.

After restoration, such vegetables and fruits do not lose their original taste - some respondents simply could not distinguish them, which indicates the high quality of the products obtained by processing fresh fruits in such drying equipment.

Infrared radiation is obtained from absolutely safe electric lamps or gas panels and screens. No harmful radiation comes from them, and all products after drying can be sent further without additional processing.

It is better to purchase specialized drying equipment for vegetables and fruits

Some people believe that any drying cabinet is suitable for drying vegetables and fruits, but this is not true - even if the cabinet is intended for use in the food industry, it is not a fact that it will cope with vegetables and fruits.

If you do not fully understand the difference, it is better to ask knowledgeable people working at specialized enterprises, or visit an exhibition (one of those organized by Expocentre) and go to the appropriate stands there.

Visiting such exhibitions is very useful, especially if you have not worked with this kind of equipment before - this way you will learn a lot about the field in which you are going to work, and you will be able to get to know representatives of the most famous companies producing such equipment.

Who is better to cooperate with in the supply of drying equipment for vegetables and fruits?

Here it is necessary to take into account several factors: price, popularity of the company, country of origin of the equipment and other additional points that will be discussed when drawing up the contract.

Don’t be afraid to ask and clarify everything that interests you about drying equipment for vegetables and fruits.

If you are just starting to promote your business and your budget is quite small, it is better to limit yourself to foreign companies of average fame or Russian manufacturers.

Select a price range in which the amount you are willing to spend on equipment will lie, and then begin to compare other parameters of the dryers offered to you.

Do not set the price too low - this way you will most likely receive absolutely poor quality drying equipment for vegetables and fruits, after which the goods cannot be sent further due to its complete unsuitability.

It is also unprofitable to buy equipment that is too expensive at the initial stages - after all, you do not know how quickly your enterprise will pay for itself, whether you will be able to stay afloat and whether you will get tired of all this activity before you get a tangible profit.

Expensive equipment from well-known manufacturers is justified in two cases: you have a large budget and you are confident of success, or you have occupied a large niche in this market for several years and are not going to retire in the near future.

If possible, ask around those who have already done this, visit a couple of forums and exhibitions, soberly assess the situation and only then decide what equipment and at what price you are willing to buy.
