Roll dryer  working principle:

1.Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer.

2.When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.

3.This gas stream can either be moving toward the discharge end from the feed end , or toward the feed end from the discharge end.

4.The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer.

5.Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated.

6.When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type.

7.Often, indirect heated dryers are used when product contamination is a concern.

Roll dryer  features:

1.Air heating system is able to allow highly efficient removal of water from fresh harvested forage, and the maximum durability of dehydrated forage.

2.Non-pollution to the target materials guarantees minimal loss of their color,favor,and mutritional ingredients;

3.smoke collector working with the air heating system adopts water-recled wet-type collecting method,and ensure the exhausted gas to satify the environmental protection requirement as well as the lowest water consumption.

 

2.New Technology Description:

Five-Column Three-Effect Distillation Process

 

Our company designs and manufactures latestFive-Column Three-Effect Distillation equipment.This new process is promoted on the basis of traditional five-column differential-pressure column and mainly used for super-fine alcohol production.

The key of this process is the heating methods,the steam heats one column directly and transfers theheat to other 4 columnsto achieve three-effect thermal coupling and energy-saving effects.

In terms of electricityefficiency, it can save 50% electricity and avoid the repairing of circulating pumps and also extend the working life of there-boilers.

Double-Mash-Column Three-Effect Distillation Process

 

This process applies to the production of general-grade alcohol& fuel ethanol, and it was awarded Chinese national patent, it is the onlysuccessfulapplicationof double mash column & three-effect in the world,which produces general-grade alcohol.

This process is composed by mash column, rectification column and composite column. The composite column functions as mash column and rectification column.

The key of this process is the heating methods: the steam heats one column directly and transfers the heat to other 2 columns to achieve three-effect thermal coupling and energy-saving effects.

The advantage of this process is energy-saving;it saves over 40% steam

Q:What are the characteristics of the drum dryer?
The main body of the rotary drum dryer is a slightly tilted and rotatable drum, and the wet material is fed from one end thereof and passes through the inside of the drum and is dried in contact with the hot air or the heated wall in the cylinder. , Chemical industry, metallurgy, building materials and other industries have a wide range of applications. Rotary drum drying and other drying equipment compared to the production capacity, continuous operation and simple structure, easy operation and less trouble, low maintenance costs
Q:How to solve the dryer a series of failures
The moisture absorption capacity of the dryer is limited, so the moisture it adsorbs must be removed by regeneration. The process is: when the ambient air is inhaled, through a filter into the blower, and then be sent to a group of heaters. The heated air passes through the machine. When the temperature of the dryer rises, the adsorbed moisture is released. When the hot air to absorb water vapor to saturation, it was discharged into the atmosphere. The high temperature regenerative dryer must be cooled before returning to the dry loop to restore the moisture absorption function of the dryer.
Q:Frozen sublimation drying equipment which consists of several systems
the vacuum system: by the freeze-drying room, condenser, vacuum valves and pipes, vacuum equipment and vacuum instrument composition, the current vacuum equipment is extremely combination of three: the Roots pump, cryogenic condenser, and multi-stage steam ejector, which , Multi-stage steam ejector structure is simple, no mechanical power, easy maintenance, low failure rate, the material requirements are not high, usually need to set 4-5 level.
Q:What are the common drying methods?
In the actual production process, for high-humidity materials are generally as much as possible first with mechanical dehydration method to remove a large number of free water, and then take other drying methods for drying.
Q:What are the types of drying equipment?
According to the heating method, the dryer is divided into convection, conduction, radiation, dielectric and other types. Convection dryer, also known as direct dryer, is the use of hot dry media and wet material in direct contact with convection way to transfer heat, and the generated steam away; Conductive dryer also known as indirect dryer, which uses conduction The heat is transferred from the heat source through the metal wall to the wet material, and the resulting wet steam can be removed by means of reduced pressure suction, passing a small amount of purge gas or condensing it on a separately provided low
Q:The working principle of belt dryer
For the material temperature does not exceed 60oC requirements, can be used about 80oC dry gas. Multi-stage combination can better play the performance of belt dryer, and dry more uniform.
Q:How to choose the right drying equipment and drying technology
For non-hygroscopic materials, the moisture present in any environment remains on the surface and becomes "surface moisture" and is easily removed.
Q:What is a combination of drying equipment?
Combination drying equipment is a combination of two or more dry forms, the main material, mainly in series, that is, when the material has been through the drying equipment, two or more drying equipment, combined dry mainly to meet a The need for a drying process.
Q:What is the best drying equipment?
In the traditional horizontal fan-type dryer, the air flow only in the material surface flow, the drawback is the low heat transfer coefficient, poor heat utilization, material drying time is long.
Q:What are the basic types of common drying equipment?
Common types of common drying equipment (1) slime dryer slime dryer its working principle is as follows: moisture content of 25 to 40% of the wet slime first after a special material scrambling device after the break up by the belt The machine is transported to the feeder, and then the wet slime is fed into the drying drum by the feeder. The slime is spread under the drying drum, and the slag is evenly dispersed and fully communicated with the hot air to reach the heat transfer, Mass transfer of purpose.
