Tips(You can visit our FAQs page to learn more):

How long does it take to dry a batch of stuffs?
We can offer you drying time range and drying process of each stuff based on our experience at Deyang city. But you must to do trial drying and debugging equipment before production.
Deyang is located in mid-latitude and belongs to the subtropical humid monsoon area. Altitude is approximately 491m. Annual average temperature is 15℃-17℃; January is 5℃-6℃; and July is 25℃. Annual average relative humidity 77%
But there still are many factors influence drying time and drying process:
1. Drying temperature.
2. Humidity domestic and water content of stuff.
3. Hot air speed.
4. Stuffs properties.
5. Shape and thickness of stuff itself.
6. Thickness of material stacked.
7. Your propiaded drying process for make flavor food.
You can imagine that if you dry clothes outdoors, the clothes will dry quickly when the temperature is higher/the humidity is lower/the wind is stronger; of course, silk pants will dry faster than jeans; bedding will dry slower, etc.
But it has limits/ranges, for example, if temperature exceeds 100℃, stuffs will burn; if wind is too strong, stuffs will be blown away and won't dry evenly, etc.

Description of redfire series drying room

Our company has developed the Red-Fire series drying room which is highly acclaimed domestically and globally. It is designed for tray-type drying and features a unique left-right/right-left periodic alternating hot air circulation system. The generated hot air cycles to ensure even heating and rapid dehydration in all directions. Automatic temperature and humidity control significantly reduces energy consumption. This product holds a utility model patent certificate.

Advantages

1.The control system adopts PLC programming + LCD touch screen, which can set up to 10 segments of temperature and humidity settings. Parameters can be adjusted according to the different properties of the stuff that make the drying process is not affected by external environmental factors, ensuring excellent color and high quality of the finished product.
2.One button start for unattended operation, automation, The machine stops after finish set drying program. It can be equipped with a remote control system, mobile app remote monitoring.
3.Left-right/right-left 360° alternating hot air circulation, ensuring uniform heating of all stuffs in the drying room, avoiding uneven temperature and mid-process adjustment.
4.The circulation fan take a high-temperature resistant, high-airflow, long-life axial flow fan, ensuring sufficient heat and rapid temperature rise in the drying room.
5.Various sources can be used, such as air heat pumps, natural gas, steam, electricity, biomass pellet, coal, firewood, diesel, hot water, thermal oil, methanol, gasoline, etc., depending on the local conditions.
6.Modular drying room which consisted of a hot air generator + drying room + drying pushcart. Low transportation cost and convenient installation. It can be assembled by two people in one day.
7.The shells of hot air generator and drying room both are made of high-density fire-resistant insulation cotton + sprayed/stainless steel sheet which are beautiful and durable.

Description of belt dryer

The Belt dryer is a commonly used continuous drying equipment, which is widely used in the drying of sheet, strip, block, filter cake, and granular in the processing of agricultural products, food, pharmaceuticals, and feed production industries. It is particularly suitable for stuffs with high moisture content, such as vegetables and traditional herbal medicine, for which high drying temperatures are not allowed. The machine uses hot air as the drying medium to continuously and mutually contact with those wet stuffs, let the moisture to disperse, vaporize, and evaporate with heat, resulting in fast drying, high evaporation intensity, and good quality of dried products.
It can be divided into single-layer belt dryers and multi-layer belt dryers. The source can be coal, electricity, oil, gas, or steam. The belt can be made of stainless steel, high temperature resistant non-stick material, steel plate, and steel belt. Under standard conditions, it can also be designed according to the characteristics of different stuffs, the machine with the characteristics of small footprint, compact structure, and high thermal efficiency. Especially suitable for drying stuffs with high-moisture, low-temperature drying required, and need a good appearance.

Features:

Low investment, fast drying, and high evaporation intensity.
High efficiency, large output, and good product quality.
Standardized production, and the number of sections can be increased according to requirements.
Air volume, heating temperature, stuffs residence time, and feeding speed can be adjusted to achieve the best drying effect
Flexible equipment configuration with the use of mesh belt flushing system and stuff cooling system.
Most of air is circulates, savings energy significantly.
Unique air distribution device is providing more even hot air distribution, ensure consistent product quality.
The heat source can be steam, air energy pump, thermal ol, electric, or gas, biomass furnace.

Applications

This equipment is mainly suitable for drying small pieces of stuffs as well as sheet, strip and granular with good fiber and good air permeability. its very suitable for products such as vegetables and traditional medicine pieces that have high moisture content, cannot be dried at high temperatures, and require final shape of the stuff to be maintained. Typical materials include konjac, pepper, jujube, wolfberry, honeysuckle. yuanhu slices, chuanxiong slices, chrysanthemums, grass, dried radish, day lilies, etc.
