Spices Dryer

Under normal circumstances, spices are dried and then sold on the market. This is because the dried spices not only retain the original flavor of the spices, but also have a much longer storage time than fresh spices. Next, Baixin Machinery will share with you several spice dryers commonly used by spice manufacturers.

At present, there are four types of spice dryers on the market, which are continuous mesh belt spices dryer, heat pump spices dryer room, microwave spices dryer and all-in-one spices dryer. These four types of spices dryers have their own advantages, and the applicable drying requirements are also different. The specific information is as follows.

1.Continuous Mesh Belt Spices Dryer

The first is continuous mesh belt spices 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.

Working Principle of Continuous Mesh Belt Spices 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 spices. 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 Spices Dryer

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

Advantages of Continuous Mesh Belt Spices Dryer

Its advantage is that the speed of drying spices 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 Spices Dryer Room

This is heat pump spices 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 Spices 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 spices, 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 Spices Dryer Room

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

Advantages of Heat Pump Spices Dryer Room

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

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

Working Principle of Microwave Spices 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.

Components of Microwave Spices Dryer

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

Advantages of Microwave Spices 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 Spices Dryer

This all-in-one spices dryer has a smaller output among the four spices 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 Spices 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”.

Components of All-in-one Spices Dryer

The components of this all-in-one spices 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.

Advantages of All-in-one Spices Dryer

The new dryer All-in-One spices 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 spices dryer. Hot air only circulates inside and no energy is lost. The energy-saving is incomparable to traditional dryers. Gentle drying at middle and low temperature, Aroma, appearance, and bioactivity are largely retained.

The above are the four kinds of spice dryers produced by Baixin Machinery, and they are also the most common spice dryers on the market. They each have their own advantages and are suitable for drying various spices. In addition, our spices dryers can be customized according to customer needs. If you are interested in our spices dryers, please feel free to contact us. We will recommend the most suitable spices dryer for you according to your situation.
