Hello, very happy with your question, based on the questions you asked, I have summarized the following points, I hope it will be useful to you.

The above is by Zhengzhou Junda Machinery Enthusiasm, 1, coal blocks,

The general calorie is 5000 kcal kg, which is the most widely used and cost-effective fuel in the past and present, but in the future, with the gradual tightening of environmental protection requirements, it is also a sand dryer fuel that is not expected to be very optimistic. It is also one of the most practical materials. Of course, coal is also divided into bituminous coal and anthracite, and most of the anthracite is selected for drying.

And it is necessary to do a good job of dust removal and exhaust gas treatment at the back end of the drying equipment.

Key features; The formalities are difficult to handle, ** not allowed. There is a cost advantage.

2. Gas, including natural gas, biogas, coal gas and all other combustible gases. The general heat is about 8500k kg, and the combustion efficiency is high. Air pollution is less, the overall cost** is slightly higher than coal, and it is affected by gas pipelines.

Key features; **Advocate. The cost is slightly higher than coal. However, it is limited by pipelines.

3. Biomass pellets.

It is a kind of fuel advocated in recent years, mainly made of wood chips and straw pellets. The high-quality pellets are pine wood chips, which are produced in the Northeast. The rest of the area is composed mainly of common wood pellets.

It is also pressed with straw. If it is used as fuel for a sand dryer. The cost is slightly higher than coal.

It's about the same as gas fuel. Not limited by pipelines.

Key features; **Advocacy, limited by sawdust resources, and a new resource, the production capacity may not be sufficient.

4. Heavy oil. Less fuel for sand dryers. However, individual areas are rich in raw materials and can be considered.

5. Electricity. The cost is higher. There is no production advantage. Not recommended.

Suggestion; In general production, two sets of combustion systems can be installed, one for environmental protection inspection and one for actual production. It is also possible to set it alone. It mainly depends on the actual situation in the customer's region.

The small grain dryer is used to dry wheat, corn, rice, beans and other grab-harvest grain crops. Users can choose dryers with different capacities according to the scale of agricultural production and the amount of grain drying process.

1. All drying machinery in China is still in the research and development stage, there is no unified classification method, generally can be divided into three categories: high temperature fast, low temperature slow and high and low temperature combination.

There are many types of high-temperature dryers, such as fluidized chute type, fountain type, drum type, circulating type, etc. Two of the representative ones are:

1) Fluidized chute type. The working principle is that the hot air is blown into the lower part of the fluidized chute by the fan, passes through the chute perforated plate at a higher flow rate, and blows the grain on the plate. The grain is blown by the hot wind and suspended and violently mixed with the hot wind, and rises, tumbles and forms a boiling state under the action of the wind.

Due to the slight downward inclination of the chute orifice, the grain is rolled towards the outlet by gravity during the rise and fall. The grain is in contact with the hot air and the heat exchange, the temperature rises quickly and uniformly, and the water evaporates continuously. Due to the rapid convective heat transfer in the fluidized layer, the time for the grain to flow through the chute is short (only about 1 minute), and the water content is reduced by about 1% through one pass. The outlet temperature is high, and the pile must be slowed down, and the moisture can be reduced by 1%.

The general rule is that the moisture decreases faster in the early stage and slower in the later stage. For the freshly harvested wet grain, it must go through 3 or 4 processes to achieve the required moisture content for storage or grain processing. This kind of dryer has a simple structure and low cost.

2) Recycling. Generally, mechanical cycle drying is used, and the method is relatively simple. During the operation, the rice is sent from the top to the fall, and enters the drying section after passing through the slow su section, and the dried grain is regularly discharged to the lower box by the grain discharge wheel, and is sent to the upper auger at the top of the dryer by the lower auger, and then evenly sprinkled in the slow su section for slow su, and then cycles again.

After many cycles of drying, it gradually reaches the storage standard. The circulating dryer has a high degree of mechanization, low labor intensity, good uniformity of drying, and the quality of grains is easy to guarantee.

Low-temperature dryer with stacking bed type and bin type. Dry the grains with hot air or natural air ventilation that is slightly higher than room temperature. As long as the thickness of the grain layer is selected appropriately and the grain layer is turned frequently, the drying effect is better, and it can be used for drying other agricultural products other than rice.

This type of dryer has low operating cost, easy operation and maintenance.

High and low temperature combination. It is a process in which high-moisture grains are dried quickly at high temperatures and then slowly dried at low temperatures to achieve a safe moisture content. It has the advantages of both high-temperature drying and low-temperature drying, and has advanced technology.

It can reduce energy consumption, save investment, reduce the grain burst rate, and improve grain quality.

Dryer structure:

All-in-one machine: the drying host and drying room are made into a container integral, including the drying room with a drying car and a drying tray Advantages: 1. Convenient and fast movement and transportation.

2. No need to debug and install, it has been tested before leaving the factory, and it can be used directly when it is connected to the power, and it can be used as a demonstration prototype and can be operated immediately.

3. There is no need for construction personnel and costs, saving construction time.

4. Sturdy and durable, not afraid of wind, sun and rain, suitable for outdoor use, and even dry products in the field.

5. Good sealing and heat preservation, so that the noise is smaller, the heat loss is less, and it is more energy-saving.

No matter how the output of the mobile grain dryer changes, the dryer can be designed as a single unit, with a small footprint and few ancillary equipment; No increase in the number of operators; Produced in the open air, no canopy required. Therefore, the higher the output, the lower the total investment cost of the system compared to the recirculating dryer, and the more obvious the advantages of high efficiency.

Adopt hot air permeable design, have a wide drying area, through the constant temperature ventilation device, automatic and rapid temperature regulation, hot air indirect heating makes the grain free of any pollution, to ensure that each grain is evenly dried, the color and smell are good, and the drying effect is of outstanding quality.

According to the relative movement direction of grain and air flow, the dryer can be divided into cross-flow, mixed flow, forward flow, reverse flow and forward and reverse flow, mixed and reverse flow, and forward mixed flow. Pure counter-flow dryer is produced and used very little, and it is mostly used with other airflow dryers, that is, it is used for the cooling section of downstream or mixed-flow dryers to form forward-counter-current and mixed-countercurrent dryers. The advantage of counter-current cooling is that the natural cold air energy can be fully in contact with the grain, which can increase the cooling rate and reduce the height of the cooling section appropriately.

The forward and counter-current, mixed and mixed flow dryers make use of their respective advantages to achieve high temperature and rapid drying, improve drying capacity, do not increase unit heat consumption, and ensure uniform grain quality and moisture content.
