How to Dry Herbs in a Dehydrator

Due to the short storage time of fresh herbs, they can only be seen in the market during the corresponding season, so most of the time we see dried herbs on the market. Dried herbs not only prolong the storage time, but also prolong the sales time, and bring higher economic benefits, so drying herbs is the most effective way for herb manufacturers to increase the added value of products. Next, Baixin Machinery will share with you how to dry herbs in a dehydrator? How does a dehydrator work?

First of all, we need to know which herb dehydrators are commonly used on the market. At present, there are four kinds of herb dehydrators produced by our Baixin Machinery,which are continuous mesh belt herb dehydrator, microwave herb dehydrator, heat pump herb dehydrator, all-in-one herb dehydrator. These four kinds of herbal dehydrators are also common in the market. Next, let's take a look at how to dry herbs in these herb dehydrators in turn.

1.Continuous Mesh Belt Herb Dehydrator

The first is continuous mesh belt herb dehydrator. 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 Herb Dehydrator

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 , and the hot air draws out the water vapor of the herb. so as to achieve the purpose of dehydrator. The operation temperature is 40-120 degree centigrade. And the dehydrate cycle is 1-5 hours.

Components of Continuous Mesh Belt Herb Dehydrator

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

Advantages of Continuous Mesh Belt Herb Dehydrator

Its advantage is that the speed of dehydrated 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.Microwave Herb Dehydrator

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

Working Principle of Microwave Herb Dehydrator

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 dehydrated. 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 dehydrated purpose.

Components of Microwave Herb Dehydrator

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

Advantages of Microwave Herb Dehydrator

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 dehydrated effect.
The microwave dehydrator can make all parts of the material have the same effect.
3:Dehydrated 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.

3.Heat Pump Herb Dehydrator

This is heat pump herb dehydrator. 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 Herb Dehydrator

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 dehydrator to circulate heating and dehydrator the herb, and the hot and humid air in the dehydrator is directly discharged to the outside of the dehydrator through the dehumidifier.

Components of Heat Pump Herb Dehydrator

The components of this heat pump herb dehydrator include: Heat Pump, Trolley Tray, Fan Frame with Fan(Axial Compressor Fan), Dehydrator Parts.

Advantages of Heat Pump Herb Dehydrator

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

4.All-in-one Herb dehydrator

This all-in-one herb dehydrator has a smaller output among the four herb 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 Herb dehydrator

Drying is take moisture away. But takes away the moisture temperature is not the most critical factor. The key for dehydrated 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”.

Components of All-in-one Herb dehydrator

The components of this all-in-one herb dehydrator 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.

Advantages of All-in-one Herb dehydrator

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

The temperature of these herb dehydrators can be adjusted, and customers can adjust the appropriate temperature according to their own dehydration needs, which is very simple and labor-saving to operate. In addition, our herb dehydrators can be customized according to customer needs. If you are interested in our herb dehydrators, please feel free to contact us. We will recommend the most suitable herb dehydrator for you according to your situation.
