In conventional or surface heating, the process time is limited by the rate of heat flow into the body of the material from the surface as determined by its specific heat, thermal conductivity, density and viscosity. Surface heating is not only slow, but also non-uniform with the surfaces, edges and corners being much hotter than the inside of the material. Consequently, the quality of conventionally heated materials is variable and frequently inferior to the desired result.

Imperfect heating causes product rejections, wasted energy and extended process times that require large production areas devoted to ovens. Large ovens are slow to respond to needed temperature changes, take a long time to warm up and have high heat capacities and radiant losses. Their sluggish performance makes them slow to respond to changes in production requirements making their control difficult, subjective and expensive.

Conversely, with microwaves, heating the volume of a material at substantially the same rate is possible. This is known as volumetric heating. Energy is transferred through the material electro-magnetically, not as a thermal heat flux. Therefore, the rate of heating is not limited and the uniformity of heat distribution is greatly improved. Heating times can be reduced to less than one percent of that required using conventional techniques.

Features :-

Microwave dryer is a dryer which uses microwave to reduce the moisture from raw material. Unlike other external heating drying, microwave dryer for spice can dry the raw material from internal and external at the same time. Using this method, microwave dryer for spice can save drying time and avoid the raw material becoming metamorphism or coking at the overheat environment. The drying effect is very good, especially for the heat sensitive food.

Conventional means of heating and drying do not compare to the efficiency of an industrial microwave dryer. Incorporating high capacity, state-of-the-art microwave drying and heating equipment ensures that your products maintain quality while you experience double to triple the throughput achieved with conventional heating equipment.

The Main components of Microwave Dryer for Spice:

1. Microwave generator system
2. Microwave box
3. Temperature controlling system
4. Humidity controlling system
5. Transmission system
6. PLC and touch screen control system
7. Humidity discharging system
8. Electrical cabinets
9. Cooling system
10. Hot air recycling and circulatory system

Applications:-
 
1. First, wet materials are put into the hopper of Airflow Dryer, then the heating generator generates hot air which mixes with wet materials and then is sucked into the drying pipes by the induced draft fan quickly.

2. The hot air going though the drying pipes, high temperature air contact with wet material, the moisture on the surface immediately began gasification, the surface temperature will gradually rise. The wet material gets fully dried during the drying process.

3. After the wet materials get dried, the dried materials are usually separated from the drying hot air with a cyclone collector.

Features :-

– The selection of Airflow Dryer models depends on the original moisture content of materials

– Airflow Dryer heat transfer coefficient is higher compared with the ordinary dryer

– Usually contact time is very short, most of the material only between 0.5-5s, the longest 5 minutes, therefore is suitable for drying heat-sensitive materials of low melting point, Airflow Dryer Contact time can be controlled.

– Airflow Dryer is simple, occupy smaller area, so it’s very convenient for smaller working site;

– Wide applicability, Airflow Dryer can be used for various powder materials, mainly sawdust, crushed straw, rice husk and so on.

– This Airflow Dryer can reduce moisture 20%-40% of the materials at one time with the advantages of lower consumption and high efficiency.

Applications:-
 
Industrial Hot Air Dryer for :
Fruits, Banana, Yam, Cassava, Apple, Papaya, Dried Fruits and Vegetables,
Pharmaceutical Products, Chemical Industry, Food Industry, Aquatic Products,
Traditional Medicines etc.

Features :-

– Excellent drying effect with yield of 100%.

– Maintains the original color and nature of materials.

– Hot air temperature 35º C – 260º C can be achieved depending on the mterial requirement.

– Multi Layer Drying.

– Economical Method of Drying

Applications:-
 
Industrial Hot Air Dryer for : Fruits, Banana, Yam, Cassava, Apple, Papaya, Dried Fruits And Vegetables,
Pharmaceutical Products, Chemical Industry, Food Industry, Aquatic Products,
Traditional Medicines etc.

Working Principle :-
 
The raw materials are evenly distributed on the conveyer belt through suitable mechanisms such as star distributor, swing belt, crusher or granulator, then the conveyer passes through the channel including several heating units. Each heating unit is equipped with air heater and circulation system. Each channel has one or several damp discharge systems. When the conveyer passes through it making the hot air will pass through the raw material from down to bottom and vice versa. In this way materials are dried evenly.

Features :-

– Hot air go through material layer from bottom to top and vice versa, it increases the contact area of material and hot air making the drying intensity.

– We adopt unique internal air blowing device which not only increases the relative speed of material and hot air and drying intensity but also makes the uniform drying of materials.

– It is fully enclosed structure. There are no outer air pipes except the dehumidifying air pipe making the improved heating efficiency and working condition

– It is easy to reach at all parts inside the main machine, making it easy for cleaning.

– The conveyor belt speed can be controlled to ensure the final moisture of products

Applications:-
 
Industrial Hot Air Dryer for : Fruits, Banana, Yam, Cassava, Apple, Papaya, Dried Fruits And Vegetables,
Pharmaceutical Products, Chemical Industry, Food Industry, Aquatic Products,
Traditional Medicines etc.

Working Principle :-
 
Autopack’s hot air circulating drying oven is equipped with low-noise & high temperature-resistant axial flow fan and automatic temperature control system. The whole circulating system is completely closed, which can improve the thermal efficiency from traditional 3-7% to current 35-45%, and the maximum thermal efficiency could be up to 50%.
The drying process is that the raw material is heated in the trays with hot air circulation, the wet moisture is taken out from material and is exhausted outside the drying chamber at the same time.

Features :-

– Hot air is circulated inside the oven to ensure a high drying efficiency and save energy.

– It uses enhanced ventilation and equipped with adjustable air distribution for uniform drying.

– It’s batch operation so can adjust process condition anytime. Thus can change product from time to time.

– Suitable for drying high-value product or small-batch product.

– Feed and dry material in tray, easy to load and unload.

– Low noise and steady operation, the temperature is controlled automatically.
