Fruit Dehydration Process

Dehydrated fruit has always been very popular, it not only retains the nutrition of the fruit itself, but also prolongs the storage time of the fruit, and effectively avoids the economic loss caused by the rot and deterioration of the fruit. Today let us discuss the fruit dehydration process together.

First of all, let's take a look at how to make dehydrated fruit at home. The first method we think of must be sun dehydration. This method is very simple, just cut the cleaned fruit into slices of about one centimeter, then spread a layer on the tray, put it under the sun, turn over every five hours and leave in the sun for about three to five days to make dehydrated fruit. In fact, we can also use the oven to dehydrate the fruit at home. The process is also very simple, that is, put the sliced fruit on the baking tray, the oven temperature is 80℃-100℃, it takes about five hours to bake, and more observations should be made during the baking period, flip in time until the moisture is dehydrated.

However, we can easily find that the quality of dehydrated fruit made at home is not always as good as those sold in the market. Next, let's take a look at the fruit dehydration process of these dehydrated fruit manufacturers. 
Dehydrated fruit manufacturers generally use professional fruit dehydration machines, which not only saves manpower, but also can produce high-quality dehydrated fruit in large quantities. The following are three common fruit dehydration machines produced by our Baixin Machinery: heat pump fruit dehydration room, continuous mesh belt fruit dehydration machine, and all in one fruit dehydration machine. Next, I will introduce these three fruit dehydration machines in turn.

1. Heat Pump Fruit Dehydration Room 

According to our sales experience, the heat pump fruit dehydration room is the choice of most dehydrated fruit manufacturers, its output is 100-5000kg/batch, and the heat source can be electricity, coal, wood chips, natural gas, diesel oil, and propane, etc.

Working Principle of Heat Pump Fruit Dehydration Room

It adopts the principle of reverse Carnot cycle. It absorbs low-temperature heat energy in the air, and becomes high-temperature heat energy after efficient heat collection and integration of the heat pump system, which is transported to the dehydration room to circulate heating and dehydration the fruit, and the hot and humid air in the dehydration room is directly discharged to the outside of the dehydration room through the dehumidifier.

Advantages of Heat Pump Fruit Dehydration Room

The advantage of this heat pump fruit dehydration room is that it can quickly remove the water in the fruit without affecting the original color, shape and nutrient content of the fruit. The fruit heat pump dehydration room is equipped with a computer control system, which can realize automatic temperature control. The dehydration temperature range of the heat pump dehydrator is 20-80°C. It has the advantages of strong dehydration capacity, better dehydration effect, simple operation, and 70% energy saving by adopting a heat pump system.

Components of Heat Pump Fruit Dehydration Room

The components of this heat pump fruit and vegetable dryer room include: Heat Pump, Trolley Tray, Fan Frame with Fan(Axial Compressor Fan), Dryer Room Parts. 

2. Continuous Mesh Belt Fruit Dehydration Machine

If the output of the dehydration room cannot meet your requirements, you can consider choosing this continuous mesh belt fruit dehydration machine. It can achieve continuous production, and the output can reach 300-2000kg/h. The main heating methods are electric heating, steam heating, hot air heating, the heat source can be coal, wood chips, natural gas, diesel, propane, electricity, etc.

Working Principle of Continuous Mesh Belt Fruit Dehydration Machine

Its main working principle is to spread the material evenly in the network. The material is moved in the dehydrator by the operation of the machine, and the hot air draws out the water vapor of the food. so as to achieve the purpose of dehydration. The operation temperature is 40-120 degree centigrade. And the dehydrate cycle is 1-5 hours.

Advantages of Continuous Mesh Belt Fruit Dehydration Machine

Its advantage is that the speed of dehydration fruit is relatively fast, and it can work continuously and uninterruptedly, so as to achieve large-scale production. Other than that, it's very flexible, it's easy or without installation, so you don't have to worry about installation.

Components of Continuous Mesh Belt Fruit Dehydration Machine

The components of this continuous mesh belt fruit dehydration machine include: Homogenizer, Feeder Conveyor, Mesh belt fruit dehydrator host, Heat source,Air Intake System, Control panel, Observation door, Output conveyor.

3. All-in-one Fruit Dehydration Machine

This all-in-one fruit dehydration machine has a smaller output among the three fruit dehydrators. Its output is 100-1500kg/batch. The heat source is mainly electricity, and it can also be coal, wood chips, natural gas, etc.

Working Principle of All-in-one Fruit Dehydration Machine

Dehydration is take moisture away. But takes away the moisture temperature is not the most critical factor. The key for dehydration is depending on relative humidity within certain space, Baixin company took advantage of the dehydrate essence, originality developed a“Closed Cycle" dehydrator, changed the traditional heat pump dehydrator "bake" to “dehumidifier”.

Advantages of All-in-one Fruit Dehydration Machine

1. The new dehydration machine All-in-One fruit dehydration machine has a compact structure, great energy-saving, wide application, high dehydration quality, easy operation, simple installation, and movable.
2. It is the best dehydration equipment for small firms, dehydration experiments, and scientific research. The uses only connect the power to use, is the easiest operation heat pump fruit dehydration machine.
3. Hot air only circulates inside and no energy is lost. The energy-saving is incomparable to traditional dehydration machines.
4. Gentle dehydration at middle and low temperature, Aroma, appearance, and bioactivity are largely retained.

Components of All-in-one Fruit Dehydration Machine

The components of this all-in-one fruit dehydration machine include:Power jack, Water outlet, Exhaust air outlet, Supporting wheels, Controller(PLC control panel), Door lock, Observation window, Circulating Air Inlet, Outlet for hot and dehydrate air, PP tray, Stainless steel tray, Supporting racks for trays.

Fruit Dehydration Machine Price

The above three are the main fruit dehydration machines in the fruit dehydration industry. Regarding the price of these fruit dehydration machines, first of all, the fruit dehydration equipment is a customized machine. Different manufacturers have different production technologies and dehydration levels. The performance, efficiency, and configuration of the fruit dehydration equipment produced are different, so the price will naturally vary greatly.
The price of the commonly used fruit dehydration room is about 3,500-50,000 US dollars, and the price of the fruit mesh belt dehydration machine is about 30,000-100,000 US dollars. In addition to the basic equipment models, customized processing can also be carried out and quotes.

The above are the fruit dehydration process and the three types fruit dehydration machines. If you want to know more, or want to buy a suitable fruit dehydration machine, you are welcome to contact us at any time, and we will recommend the most suitable one for you according to your needs.
