Working principle of mesh belt dryer

The continuous conveyor dryer is a batch and continuous production drying equipment. The main heating methods include steam heating and heat pump hot air heating.

The main principle of the industrial belt dryer is to spread the materials evenly on the mesh belt. The mesh belt is made of 12-60 mesh PET woven mesh belt, which is driven by the transmission device to move back and forth in the dryer. The hot air flows between the materials. Then, the water vapor is forced to be dehumidified and discharged through the dehumidification fan, thereby achieving the purpose of hot air drying.

Mesh belt dryer price

The mesh belt dryers currently on the market have different specifications and models, and the prices are also different. Therefore, when consulting the price of mesh belt dryers, you must first determine your own needs, and secondly, consider the heat source method and material of the equipment.

Only by clearly understanding your needs, required equipment configuration, etc., can we provide customers with corresponding equipment quotation information, or provide customers with dryer customization services.

In fact, there are many factors that affect the price of belt dryer machines. Generally, the size, material, heat source matching, equipment quality, production efficiency, after-sales service, manufacturer strength, etc. of the mesh belt dryer need to be considered.

• Size of the continuous belt dryer: The larger the equipment, the greater the material drying output, and the more expensive the mesh belt dryer is;
• Material style: Currently, polyurethane, color steel, baking paint, stainless steel, etc. can be used to produce continuous vacuum belt dryers. We can also choose according to our own production needs;
• Heat source matching: There are many heat source methods for mesh belt dryers. They can use gas, steam, electricity, heat pump air energy, coal, firewood, biomass pellets, etc. Different heat source methods have different matching heat exchangers. Likewise, the cost of equipment will naturally vary.

mesh belt dryer design

Here, RICHI will show you the principles and key elements of our engineer team’s design of mesh multi-layer belt dryers.

As drying technology accounts for an increasing proportion in life and production, people have put forward higher requirements for drying functions. Aiming at the common problems of existing drying equipment such as low heat utilization efficiency, serious pollution, and large floor space.

Therefore, in response to these problems, RICHI MACHINERY’s engineering team designed a mesh drying equipment with relatively complete functions. A versatile drying equipment should be able to meet the requirements of small footprint and easy maintenance.

RICHI mesh belt dryer can fulfill the above basic requirements to the greatest extent possible under the prerequisite of drying large quantities of feed, food, snacks, nuts and agricultural products.

So, how is a belt dryer with such obvious advantages designed and manufactured?

1. First of all, an excellent mesh belt dryer should have an efficient hot air circulation system.
   The design of the hot air circulation system directly affects the energy consumption and drying effect of the dryer. Through reasonable hot air circulation design, RICHI can make full use of the thermal energy of hot air, improve thermal energy utilization and reduce energy consumption. At the same time, good hot air circulation can also heat the materials evenly and improve the drying effect.
2. Secondly, the structural design of the mesh dryer is also very important.
   RICHI mesh belt type multi-layer dryer usually consists of upper and lower multi-layer mesh belts. Materials enter from the upper mesh belt and go out from the lower mesh belt after passing through the drying area.
   Therefore, the design and layout of the mesh belts have been carefully considered. Properly designed mesh belts can ensure smooth transportation of materials and avoid problems such as blockage and material leakage. At the same time, appropriate mesh belt tension adjustment can also ensure the stable operation of materials.
3. In addition, the temperature control of the continuous belt dryer is also a key element.
   The control of hot air temperature directly affects the drying speed and quality of materials. RICHI engineers have reasonably set up the hot air temperature control system to ensure that the hot air temperature fluctuates within an appropriate range to avoid adverse effects on materials caused by excessively high or low hot air temperatures.
   At the same time, the drying characteristics and needs of different materials should be taken into consideration and corresponding temperature adjustments should be made.
4. In addition, the durability and ease of maintenance of the mesh belt dryer are also important considerations.
   RICHI engineers select high-quality materials and components for customers to ensure the stability and reliability of the dryer during long-term operation. In addition, the reasonable establishment of equipment maintenance facilities such as inspection openings and cleaning openings can facilitate daily maintenance and cleaning work and extend the service life of the equipment.
5. Finally, the safety of the belt drying machine cannot be ignored.
   Reasonable safety protection facilities can prevent operators from accidents during operation. For example, RICHI engineers have installed overload protection devices, leakage protection devices, etc. to ensure the safety of the operation process. In addition, for flammable and explosive materials, corresponding fire prevention and explosion-proof measures should be taken to ensure the safety of the operating environment.

How to choose a belt dryer machine?

As can be seen from the above content, the multi-layer mesh belt dryer is a commonly used continuous drying equipment. It can be widely used in the feed industry, food, agriculture, grain, building materials, chemical industry and other industries. It is especially suitable for air-permeable materials.

For the drying of sheet, strip, and granular materials, pasty materials such as filter cakes can also be dried after being formed by a pellet machine or extruder machine. The quality of the multi-layer mesh belt dryer is largely Affects product quality.

For this reason, it is important to choose high-quality multi-layer mesh belt dryers and dryer manufacturers. So, for enterprises, how should they choose the appropriate multi-layer mesh belt dryer and dryer manufacturer?

• Output of mesh belt dryer.
  The customer first knows in his mind how much output he wants, and what is his hourly output requirement? Approximately what is the annual output?
• The temperature of the mesh belt dryer.
  The customer himself first tells the dryer manufacturer what he wants to dry? For example, drying feed and food is very different from drying fruits and vegetables.
• Number of layers of mesh belt dryer.
  The mesh belt dryer is a space-saving equipment. In order to meet the customer’s workshop requirements, we usually consider the size of the customer’s workshop to customize the number of layers of the dryer and try to save space.
• The length, width and height of the mesh belt dryer.
  When ordering a mesh belt dryer, customers should first measure the size of their workshop space and provide it to the manufacturer as one of the conditions for designing and manufacturing the dryer.
• Material of mesh belt dryer.
  The outer shell of the mesh belt dryer is generally made of carbon steel or stainless steel. Customers can choose the material of the dryer box according to their own situation. So far, hundreds of dryer equipment exported by RICHI are all made of stainless steel.
• Heating method of mesh belt dryer.
  When purchasing, customers should first consider whether they are suitable for electric heating and whether the electricity bill is appropriate? Is it a good deal? Are the environmental requirements high? Coal-fired heating? Natural gas heating or thermal oil heating? Steam heating? Hot air heating? . . . In short, customers should consider their own local energy conditions and even environmental protection requirements. Currently, the most common heat sources are natural gas and electricity.
• Drying effect of mesh belt dryer.
  Customers need to understand the drying purpose you want to achieve and what moisture content you want the materials to be dried to achieve.
