Dryers in Food Industry

In the food market, dried food has always occupied an important position. The food drying industry has always had good development prospects. With the development of technology, the drying level of the food drying industry has become more and more specialized. Next, I will introduce the dryers in food industry produced by Baixin Machinery.

There are four types most common dryers in food industry, namely continuous mesh belt food dryer, heat pump food dryer room, microwave food dryer and all-in-one food dryer. These four types of food dryers have their own advantages, and the applicable drying requirements are also different. The specific information is as follows.

1.Continuous Mesh Belt Food Dryer

The first is continuous mesh belt food dryer. 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.

Components of Continuous Mesh Belt Food Dryer

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

Working Principle of Continuous Mesh Belt Food Dryer

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 dryer. The operation temperature is 40-120 degree centigrade. And the dry cycle is 1-5 hours.

Advantages of Continuous Mesh Belt Food Dryer

Its advantage is that the speed of drying food 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.

2.Heat Pump Food Dryer Room 

This is heat pump food dryer room. Its output is 100-5000kg/batch, and the heat source can be electricity, coal, wood chips, natural gas, diesel oil, and propane, etc.

Components of Heat Pump Food Dryer Room

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

Working Principle of Heat Pump Food Dryer 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 dryer room to circulate heating and dryer the food, and the hot and humid air in the dryer room is directly discharged to the outside of the dryer room through the dehumidifier.

Advantages of Heat Pump Food Dryer Room

The advantage of this heat pump food dryer room is that it can quickly remove the water in the food without affecting the original color, shape and nutrient content of the food. The food heat pump dryer 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.

3.Microwave Food Dryer

This one is microwave food dryer. Its output is 100-2000kg/h. The drying time is 2-5min.

Components of Microwave Food Dryer

The microwave food dryer mainly has six components,Microwave Chamber, Water Tower, PLC Control Panel, Feeding Part, Conveyor, Monitoring Window.

Working Principle of Microwave Food Dryer

Microwaves are electromagnetic waves at a frequency of 300 MHz to 300 GHz.The material in the heating medium in the molecules of water is a polar molecule. It is the rapidly changing under high-frequency magnetic field, its polarity orientation will be with the change of external electric field changes, resulting in molecular motion and friction between the effect, this field of the microwave field can be transformed into thermal energy within the medium, the temperature of the material increased, heating and puffing a series of physical and chemical processes, to achieve the purpose of microwave heating and drying. During the equipment is working the microwave generator produces the microwave. The materials enter into the heating chamber by conveyor. At this time, moisture and bacteria inside the material evaporate under the action of microwave energy to achieve unfreeze sterilization ripening fixing drying purpose.

Advantages of Microwave Food Dryer

1:Fast processing efficiency:
It takes about a few minutes to complete the process from feeding to discharging. The processing efficiency is fast and the effect is good。
2:Uniform drying effect。
The microwave dryer can make all parts of the material have the same effect.
3:Drying and sterilizing simultaneously, tunnel type design, cover small area, continuous production，
4:Clean and sanitary: it will not pollute the material, nor change the color, fragrance, and nutritional content of the material.

4.All-in-one Food Dryer

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

Components of All-in-one Food Dryer

The components of this all-in-one food dryer 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.

Working Principle of All-in-one Food Dryer

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”.

Advantages of All-in-one Food Dryer

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

Food Dryer Price

Regarding the price of these food dryer machines, first of all, the food dryer equipment is a customized machine. Different manufacturers have different production technologies and dryer levels. The performance, efficiency, and configuration of the food dryer equipment produced are different, so the price will naturally vary greatly.
The price of the commonly used food dryer room is about 3,500-50,000 US dollars, and the price of the food mesh belt dryer 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.

These are the dryers commonly used in the food industry. If you are interested in our food dryer, please feel free to contact us, we will give you more detailed information and recommend suitable ones according to your needs.
