Herb Drying Machines

Herbs generally have a fixed growth cycle and picking time, and fresh herbs that have just been picked have a very short storage time. So in order to solve this problem, people dry the fresh herbs to prolong the storage time of the herbs. With the advancement of technology, traditional drying methods are gradually eliminated by herb drying manufacturers, and herb dryings that can not only mass produce but also save labor costs are selected. Next, I will share with you several herb dryings produced by Baixin Machinery.

At present, there are four types most common herb drying machines on the market, namely continuous mesh belt herb drying machine, heat pump herb drying room, microwave herb drying machine and all-in-one herb drying machine. These four types of herb dryings have their own advantages, and the applicable drying requirements are also different. The specific information is as follows.

1.Continuous Mesh Belt Herb Drying Machine

The first is continuous mesh belt herb 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.

Components of Continuous Mesh Belt Herb Drying Machine

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

Working Principle of Continuous Mesh Belt Herb Drying Machine

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

Advantages of Continuous Mesh Belt Herb Drying Machine

Its advantage is that the speed of drying herb 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 Herb Drying Room

This is heat pump herb drying 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 Herb Drying Room

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

Working Principle of Heat Pump Herb 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 herb, and the hot and humid air in the drying room is directly discharged to the outside of the drying room through the dehumidifier.

Advantages of Heat Pump Herb Drying Room

The advantage of this heat pump herb drying room is that it can quickly remove the water in the herb without affecting the original color, shape and nutrient content of the herb. The herb 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 drying 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 Herb Drying Machine

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

Components of Microwave Herb Drying Machine

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

Working Principle of Microwave Herb Drying Machine

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 Herb Drying Machine

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 drying 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 Herb Drying Machine

This all-in-one herb drying machine has a smaller output among the four herb drying machines. 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 Herb Drying Machine

The components of this all-in-one herb 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.

Working Principle of All-in-one Herb 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" drying, changed the traditional heat pump drying "bake" to “dehumidifier”.

Advantages of All-in-one Herb Drying Machine

The new drying machine All-in-One herb drying machine has a compact structure, great energy-saving, wide application, high drying quality, easy operation, simple installation, and movable. 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 herb drying machine. Hot air only circulates inside and no energy is lost. The energy-saving is incomparable to traditional drying machines. Gentle drying at middle and low temperature, Aroma, appearance, and bioactivity are largely retained.

Herb Drying Machine Price

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

These four are the most commonly used herb drying machines on the market. They each have their own advantages and are suitable for drying various herbs. In addition, our herb drying machines can be customized according to customer needs. If you are interested in our herb drying machines, please feel free to contact us. We will recommend the most suitable herb drying machine for you according to your situation.
