b. Clean and powerful high air volume hot air sulfur free rapid drying, simulating the principle of natural air drying, uniform drying, natural color of finished products, and excellent natural flavor retention. Natural medicinal properties last for a long time.

c. High efficiency, the drying efficiency is several times higher than various heat source air source heat pump drying rooms and ovens, and the drying time is equivalent to one sixth to one tenth of that of air source heat pump drying rooms. The batch processing pace is directly accelerated; Drying 1 ton of fresh material consumes less than one ninety percent of its electricity, reducing equipment procurement funds and labor costs.

d. The equipment has a large amount of disposable materials, making it easy to meet batch processing needs; Low purchase funds, excellent insulation performance of the equipment itself, and extremely low energy consumption.

e. Drying tasks are easier. Eliminating the three major steps of "layered loading, cart transportation, and unloading" greatly simplifies the tedious operation process, reduces manpower investment and operational steps, and improves overall work efficiency.

f. The non tube indirect heating hot air stove adopts boiler steel plate for the furnace core, which has strong corrosion resistance and a 40% increase in heat transfer speed. Its service life is several times longer than that of ordinary manufacturers providing fire tube stoves, and it benefits long-term from a single investment, reducing equipment replacement costs.

g. There is a wide range of heat source options, including coal, chopped wood, diesel, natural gas, electricity, and biomass pellets as fuel. One key ignition/one key shutdown/automatic feeding/automatic temperature control/digital display, the hot blast stove runs automatically according to the set program, and is equipped with energy-saving and consumption reducing heat sources that comply with relevant environmental policies.

Flat bed rapid dryer is a standardized drying machine developed to meet the economic development needs of rural and mountainous areas, serving the agricultural and sideline product processing industry for rural revitalization. It is commonly used for drying agricultural and forestry by-products, economic crops, and other items. In addition to drying grains and seeds such as rice, wheat, and corn, it can also dry various economic crops (such as cowpeas, star anise, pepper, grass fruit, radish, fungus, edible fungi, wild vegetables, Chinese medicinal materials, cotton, peanuts, chili peppers, walnuts, longan, melon seeds, ginger, garlic, taro, bamboo shoots, pumpkin, fig, lychee, banana slices, peach slices, red dates, apricots, preserved fruits, candied fruits, cowpeas, spices, etc.) and other items (noodles, bamboo chopsticks, bamboo curtains, mats, silkworm cocoons, etc.). It can be widely applied to grain stations, seed companies, supply and marketing cooperatives, traditional Chinese medicine companies, farms, pastoral areas and other units.

2. If it is only the drying of Chinese medicinal herbs and herbal slices leaves, flowers, and stems. Choose a flip board dryer (with manual and automatic options)

Using strong clean air and high air volume for rapid drying, the drying materials are produced according to the tea drying standard process equipment. They fall layer by layer in sequence without the need for hand contact, keeping the materials intact. Simulating the principle of outdoor natural air drying, the one-time loading capacity is large, the temperature can be adjusted freely, the temperature is divided into high and low zones, first in first out, uniform drying, and the drying efficiency is several times higher than various heat source air source heat pump drying rooms and ovens, greatly reducing the labor intensity and cost of drying. The drying time is greatly shortened, and the equipment purchase funds and labor costs are reduced. Short drying time maintains the natural color and excellent natural medicinal properties of the finished product.

3. If drying traditional Chinese medicinal materials and herbal decoction pieces in the form of flowers, thin slices (referred to as thick slices in traditional Chinese medicine), strips, large granules, rods and other materials, the purchase cost is relatively high and the degree of automation is high. Choose a mesh belt dryer.

Adopting multi-layer belt drying, a multi-layer mesh conveyor belt is installed in the drying oven. Under the drag of the reducer, the first layer of conveyor belt moves longitudinally in the drying oven, and the transmission mechanism makes the remaining layers move longitudinally back and forth. The feeding device evenly distributes the material on the first layer of conveyor belt. When the material reaches the end of the conveyor belt, it automatically flips to the next layer of conveyor belt, and the material runs alternately in reverse until the last layer is dried. After drying, the material is cooled by the cooling section and then transported by the discharge conveyor belt to the packaging area for automatic packaging

Every hour, tens of thousands of cubic meters of pure hot and dry air are forcibly sent into the drying body by a hot air fan, and the material is washed away to exchange heat with it, causing the free water on the surface of the material to obtain energy and vaporize, and then carried away by the cooled airflow. The moisture inside the material is transferred to the outside, and the moisture generated after heat exchange is forcibly discharged outside the machine by a specially set dehumidification fan. In this way, the material is gradually dried to the required standard. Due to the fact that the dried object is in a relatively static state inside the dryer and can be flipped multiple times during the drying process, it can not only dry fragile items but also ensure uniform drying.

The machine consists of a feeding system, a discharging system, a hot air duct, a hot air stove, a dryer, a transmission system, a deceleration system, a control system, etc.

4. The drum dryer is suitable for drying granular, flaky, and stem shaped materials that require frying (including roasting) and steaming. It is also suitable for root and stem medicinal materials such as Huangjiu, which can be dried and moistened in one.

5. Small household electric heating dryer

Capacity of 150 kilograms, low purchase cost, automatic temperature control, easy operation.

2、 Difference and Selection of Drying Machines

Flat bed dryer and mesh belt dryer. With the same daily processing capacity of 15 tons and the same quality and quantity of labor, the purchase cost of a flat bed dryer is more than 100000 yuan lower than that of a mesh belt dryer. The daily power consumption is less than one-third of that of a mesh belt dryer, and it can quickly dry thick and coarse pieces that cannot be dried by the mesh belt dryer, as well as granular and powdered agricultural materials that can be dried by stacking.

Flat bed dryer is suitable for manufacturers in the initial stage who fully control the cost of raw materials and processing costs. It is used year-round to process various varieties and shapes of agricultural and sideline products; The mesh belt dryer is suitable for receiving national special support funds, but with raw material costs as the main cost control, large-scale manufacturers specialize in producing and processing specific agricultural products for use.

3、 Selection of heat source for dryer

Due to its low heating value, the drying efficiency is much lower than other environmentally friendly heat sources (biomass pellets, natural gas), and the cost of use is also much higher than other environmentally friendly heat sources (biomass pellets, natural gas). Prioritize the use of biomass pellet fuels that meet national environmental protection requirements in the processing of low value-added agricultural products (produced throughout the country); Secondly, natural gas with higher usage costs can be chosen; When natural gas is inconvenient, electric heating is ultimately chosen.
