Fruit Drying Process

Dried 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 drying process together.

First of all, let's take a look at how to make dried fruit at home. The first method we think of must be sun drying. 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 dried fruit. In fact, we can also use the oven to dry 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 dry.

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

1. Heat Pump Fruit Drying Room

According to our sales experience, the heat pump fruit drying room is the choice of most dried 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 Drying 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 drying room to circulate heating and drying the fruit, and the hot and humid air in the drying room is directly discharged to the outside of the drying room through the dehumidifier.

Components of Heat Pump Fruit Drying Room

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

Advantages of Heat Pump Fruit Drying Room

The advantage of this heat pump fruit drying 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 drying room is equipped with a computer control system, which can realize automatic temperature control. The drying temperature range of the heat pump dryer is 20-80°C. It has the advantages of strong drying capacity, better drying effect, simple operation, and 70% energy saving by adopting a heat pump system.

2. Continuous Mesh Belt Fruit Drying Machine

If the output of the drying room cannot meet your requirements, you can consider choosing this continuous mesh belt fruit drying 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 Drying Machine

Its main working principle is to spread the material evenly in the network. The material is moved in the dryer 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 drying. The operation temperature is 40-120 degree centigrade. And the dry cycle is 1-5 hours.

Components of Continuous Mesh Belt Fruit Drying Machine

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

Advantages of Continuous Mesh Belt Fruit Drying Machine

Its advantage is that the speed of drying 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.

3. All-in-one Fruit Drying Machine

This all-in-one fruit drying machine has a smaller output among the three fruit dryers. 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 Drying Machine

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

Components of All-in-one Fruit Drying Machine

The components of this all-in-one fruit drying 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 dry air, PP tray, Stainless steel tray, Supporting racks for trays.

Advantages of All-in-one Fruit Drying Machine

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

Fruit Drying Machine Price

The above three are the main fruit drying machines in the fruit drying industry. Regarding the price of these fruit drying machines, first of all, the fruit drying equipment is a customized machine. Different manufacturers have different production technologies and drying levels. The performance, efficiency, and configuration of the fruit drying equipment produced are different, so the price will naturally vary greatly.
The price of the commonly used fruit drying room is about 3,500-50,000 US dollars, and the price of the fruit mesh belt drying 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 drying process and the three types fruit drying machines. If you want to know more, or want to buy a suitable fruit drying machine, you are welcome to contact us at any time, and we will recommend the most suitable one for you according to your needs.
