How to Dry Herbs for Tea

The herbs used for making tea on the market are all dried herbs. This method can not only retain the original fragrance of the herbs, but also greatly prolong the storage time of the herbs, so it is very popular with people. Today, Baixin Machinery will share it with you how to dry herbs for tea.

Using professional drying equipment to dry herbs is the choice of most herb producers because it can achieve mass production and reduce labor costs. At present, there are four kinds of common herbal dryers, namely continuous mesh belt herb dryer machine, heat pump herb dryer room, microwave herb dryer machine and all-in-one herb dryer machine. The following is a detailed introduction of these herbal dryers.

1.Heat Pump Herb Dryer Room 

The first is heat pump herb 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.

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

Components of Heat Pump Herb Dryer Room

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

Advantages of Heat Pump Herb Dryer Room

The advantage of this heat pump herb dryer 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 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.

2.Microwave Herb Dryer Machine

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

Working Principle of Microwave Herb Dryer 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.

Components of Microwave Herb Dryer Machine

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

Advantages of Microwave Herb Dryer 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 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.

3.Continuous Mesh Belt Herb Dryer Machine

This is continuous mesh belt herb dryer 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 Herb Dryer 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 herb. so as to achieve the purpose of dryer. The operation temperature is 40-120 degree centigrade. And the dry cycle is 1-5 hours.

Components of Continuous Mesh Belt Herb Dryer Machine

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

Advantages of Continuous Mesh Belt Herb Dryer 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.

4.All-in-one Herb Dryer Machine

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

The components of this all-in-one herb dryer 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 Herb Dryer Machine

The new dryer machine All-in-One herb dryer machine 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 herb 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.

Herb Dryer Machine Price

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

The above are several drying equipment that can be used to dry herbs for tea. The drying temperature and drying time of these equipment can be adjusted, and the operation is simple. If you want to know more, you can contact us at any time. Tell us your needs.
